The Portlets in Plone are quite handy but I'd like to be able to provide some method to users to be able to temporarily hide/show the portlets column. That is, by clicking a button, the portlets column should collapse and you see the content page in full width. Then clicking again and the portlets panel on the left expands and the main content page width shrinks to accommodate.
I've observed the HTML ID of the portlets column is "portal-column-one" and I tried adding a button to the page that runs javascript to set the visibility property of that element to "hidden" but this seemed to have no effect. I was able to go into Firebug and add style="visibility:hidden;" to the "portal-column-one" element and it had the effect of making the region invisible w/o resizing the page.
I am using Plone 4.1. I have the site configured with navigation portlet on all pages except the main page which has Navigation, Review List and Recent Changes.
So it seems it must be possible to embed some javascript in the page (I was thinking of adding this to the plone.logo page which I've already customized). But I guess its more complicated than the few stabs I've made at it.
Thanks in advance for any advice.
Solution (Thanks to input from Ulrich Schwarz and hvelarde):
The solution I arrived at uses JavaScript to set CSS attributes to show/hide the Portlets Column (Left side) and expand the content column to fill the space the porlets column filled.
I started by customizing the Plone header template to add a link for the user to toggle the view of the Porlets column. I also put the necessary javascript functions in this header.
To customize the header, go to the following page (need to be logged in as Admin of your Plone site):
http://SERVER/SITE/portal_view_customizations/zope.interface.interface-plone.logo
Where:
SERVER is the address and port of your site (e.g. localhost:8080)
SITE is the short name of your Plone Site
To create this page:
Go to Site Setup (as Admin)
Go to Zope Management Interface
Click on "portal_view_customizations"
Click on "plone.logo" (or at least this is where I choose to put the button so it would be located just above the navigation Portlet)
Add the following to the page:
<script>
function getById(id) {
return document.getElementById(id);
}
function TogglePortletsPanel() {
var dispVal = getById('portal-column-one').style.display
if( dispVal == "none") { // Normal display
SetPortletsPanelState("inline");
} else { // Full Screen Content
SetPortletsPanelState("none");
}
}
function SetPortletsPanelState(dispVal) {
var nav = getById('portal-column-one');
var content = getById('portal-column-content');
if( dispVal == "none") { // Normal display
nav.style.display='none';
content.className='cell width-full position-0';
// Set cookie to updated value
setCookie("portletDisplayState","none",365);
} else { // Full Screen Content
nav.style.display='inline';
content.className='cell width-3:4 position-1:4';
// Set cookie to updated value
setCookie("portletDisplayState","inline",365);
}
}
function InitializePortletsPanelState() {
var portletDisplayState=getCookie("portletDisplayState");
//alert("portletDisplayState="+portletDisplayState)
if (portletDisplayState!=null) SetPortletsPanelState(portletDisplayState);
}
function setCookie(c_name,value,exdays) {
//alert(c_name+"="+value);
// cookie format: document.cookie = 'name=value; expires=Thu, 2 Aug 2001 20:47:11 UTC; path=/'
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var exp= ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + escape(value) + exp + "; path=/";
}
function getCookie(c_name) {
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++) {
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name) return unescape(y);
}
}
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {oldonload(); }
func();
}
}
}
addLoadEvent(InitializePortletsPanelState);
</script>
<a style="font-size:50%;" href="javascript:TogglePortletsPanel();">Toggle Portlets Panel</a>
6. Save the page
Notes:
I got the names of the plone div elements using Firebug.
I also used Firebug to experiment with different settings to speed up prototyping. For example, editing the HTML inline to verify settings do as expected.
There is a slight but of delay until the Left Portlet panel is hidden. This is only obvious on Safari for me (which is probably due to how fast it is) but not on Firefox or IE.
Maybe it's just a matter of setting the right property: you want display:none, not visibility:hidden.
But even then, the content area will probably not reflow automatically, you'll need to (dynamically) change the class on it as well.
Specifically, you'll need to put classes width-full and position-0 on portal-column-content, instead of width-1:2 and position-1:4.
This must be achieved client side by javascript (jquery).
You must first read documentation about the css grid framework used by plone: deco.gs. The website is down so, git clone this repo: https://github.com/limi/deco.gs and open pages in a webbrowser
Note: you just have to change css classes on the containers.
Try adi.fullscreen, it respects Plone's css-structure as Ulrich Schwarz thoughtfully mentioned.

I have homepage which is created by using multiple small template pages in wordpress. I have set menus on it . now i want to go on particular section/ template using menu. like if i press contact menu button then it should go smoothly downwards of homepage where the contact template has been called. I am using "Page scroll to id" plugin of wordpress but its not working. I have also seen that this plugin work when the page is created by dashoard page. Please help me , how can i navigate to my template page/section using this plugin. If any other plugin is there , please tell me about it . i will try to use that too.
Thanks
To create smooth scroll on link click follow the below steps :
Step 1: Add section ids in menu href including #section1 from admin section Appearance >> Menu .
Step 2: Create section or div with id name section1.
<div id="section1"></div>
Step 3: Paste the below code under your custom js file.
$(document).ready(function(){
// Add smooth scrolling to all links
$("a").on('click', function(event) {
// Make sure this.hash has a value before overriding default behavior
if (this.hash !== "") {
// Prevent default anchor click behavior
event.preventDefault();
// Store hash
var hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll
// The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
$('html, body').animate({
scrollTop: $(hash).offset().top
}, 800, function(){
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
});
} // End if
});
});
I hope it will helps you.
How can I set scrolling = "no" at the iframe podio-webform-frame?
Unfortunately it's possible in fully-conforming HTML5 with just HTML and CSS properties
view the automatic iframe generated by podio
Podio Webforms' iframe attributes are not customisable beforehand, but you can manipulate the attributes on it using, for example, JQuery.
Take a look at this SO answer for more info: https://stackoverflow.com/a/10083740/2904025
Example from Marcelo's code:
$('.podio-webform-frame').on("load", function() {
$('.podio-webform-frame').attr("scrolling", "no");
});
$("iframe").each(
function(index, elem) {
elem.setAttribute("scrolling","no");
}
);
I can recommend this solution, worked for me (compared to the one above which did not work). You can also add more attributes, just add a new line in that case, e.g.
elem.setAttribute("height","1159");
I have multiple DIV elements on my page with the class "grid-item-container"
I want to make the background-color of each one different. I will set an array of 5 different colours that can be set.
There is a script available here that seems to do this: http://jsfiddle.net/VXG36/1/
$(document).ready(function() {
var randomColors = ["green","yellow","red","blue","orange","pink","cyan"];
$(".random").each(function(index) {
var len = randomColors.length;
var randomNum = Math.floor(Math.random()*len);
$(this).css("backgroundColor",randomColors[randomNum]);
//Removes color from array so it can't be used again
randomColors.splice(randomNum, 1);
});
});
I cannot however get it to run on my page. Is there something in this script that needs to be amended to make it Wordpress friendly?
Kind regards
Dave
You might wan't to wrap it in something like this:
jQuery(document).ready(function($) {
// Inside of this function, $() will work as an alias for jQuery()
// and other libraries also using $ will not be accessible under this shortcut
});
The jQuery library included with WordPress is set to the noConflict() mode (see wp-includes/js/jquery/jquery.js). This is to prevent compatibility problems with other JavaScript libraries that WordPress can link. Read more about it in Codex here.
Also, change $(.random) to $(.grid-item-container), this targets the class of your div.
I've coded a script for this web page.
That allows me to use the thumbnails on the right hand side in order to switch the 'main video'.
All appears to work fine, however if you play one video and then switch to another, and then switch BACK to the video that was originally playing, then the volume is muted when you continue watching it.
I have noticed that you can get around it by clicking the volume tool inside the player, but the average user most likely won't figure this out.
I've tried using the setVolume() method on something like:
$('#media video')
But FF tells me that the method doesn't exist. Could this be because I'm just trying it from within one of my other js files whereas the media player script itself is setup with Wordpress? I'm using the WP plugin you see.
Has anyone else had this issue?
Here is my .js that switches the videos if that helps:
$(document).ready(function() {
// swap media
$('#media-feed .thumb a').click(function() {
var mediaId = $(this).prev('input').val();
$('#media .content').each(function() {
if($(this).css('display') == 'block') {
$(this).fadeOut(350);
}
});
$('#media-' + mediaId).delay(500).fadeIn(350);
return false;
});
// swap sidebar detail
$('#media-feed .thumb a').mouseenter(function() {
var mediaId = $(this).prev('input').val();
$('#media-feed .detail').each(function() {
if($(this).css('display') == 'block') {
$(this).slideUp(125, function() {
var currentDetail = $('#media-detail-' + mediaId);
currentDetail.slideDown(125, function() {
currentDetail.css('display', 'block');
});
});
}
});
return false;
});
});
Also another problem I'm having is in Internet Explorer (all versions). See above, where I said about switching from one video to another, in other browsers the videos automatically pause when you click on another thumbnail. However in IE the videos continue to play. So basically, you'd have to pause the video and THEN change main video by clicking one of the thumbnails. Again, not very user friendly.
Does anyone know of a way I can get it to function like in other browsers? I can see that even IE doesn't have this problem on this page where the Fancybox plugin is used.
So that makes me think there must be a way to solve it in IE on the home page.
If anyone has any advice on this too that would be great!
Thanks.
I have a page for an internal app that displays document images streamed from a document storage system using a web service. The problem I am having is that when a user does their search they may get hundreds of hits, which I have to display on one large page so they can print them all. This works fine in Firefox, but in IE it stops loading the images after a while so I get a hundred or so displayed and the rest just have the broken image symbol. Is there a setting somewhere that I can change this timeout?
If the issue is indeed a timeout, you might be able to work around it by using a "lazy load" script and adding new images to the document only after existing images have loaded.
There are a lot of ways to do this, but here's a simple example I threw together and tested. Instead of this:
<img src="image001.jpg" />
<img src="image002.jpg" />
<img src="image003.jpg" />
<img src="image004.jpg" />
<!-- Etc etc etc -->
You could do this:
<div id="imgsGoHere">
</div>
<script type="text/javascript">
function crossBrowserEventAttach(objectRef, eventName, functionRef)
{
try {
objectRef.addEventListener(eventName, functionRef, false);
}
catch(err) {
try {
objectRef.attachEvent("on" + eventName, functionRef);
}
catch(err2) {
// event attachment failed
}
}
}
function addImageToPage()
{
var newImageElement = document.createElement("img");
newImageElement.src = imageArray[nextImageNumber];
var targetElement = document.getElementById("imgsGoHere");
targetElement.appendChild(newImageElement);
nextImageNumber++;
if (nextImageNumber < imageArray.length) {
crossBrowserEventAttach(newImageElement, "load", addImageToPage);
crossBrowserEventAttach(newImageElement, "error", addImageToPage);
}
}
var nextImageNumber = 0;
var imageArray = new Array();
imageArray[imageArray.length] = "image001.jpg";
imageArray[imageArray.length] = "image002.jpg";
imageArray[imageArray.length] = "image003.jpg";
// .
// .
// .
// Snip hundreds of rows
// .
// .
// .
imageArray[imageArray.length] = "image999.jpg";
addImageToPage();
</script>
Each image is added to the page only after the previous image loads (or fails to load). If your browser is timing out, I think that will fix it.
Of course, the problem might actually not be a timeout, but rather that you're running out of memory/system resources and IE is giving up. Or there might be an IE DOM limitation like Sra said.
No final solution, but some hints...
I think the ie Dom hangs up. I,ve seen this in other cases. I needed simply to show the images and used a js which loads the image the time they came into focus, but that want work if you directly hit print I think. Can you use the new css ability to store imagedata directly instead of links. That should solve your problem. I am not quite sure but I think it is supported since ie 7
My guess is that you have to work around the IE setting, the easiest way to do it is simply not showing images that are not loaded or replacing them with a default image:
your html:
<img src="http://domain.com/image.jpg" />
your js:
$('img').load(function(){
// ... loaded
}).error(function(){
// ... not loaded, replace
$(this).attr('src','/whatever/default.jpg');
// ... not loaded, hide
$(this).hide();
});
That is a problem with microsoft. Unfortunately, this is a setting that would have to be changed on every single computer, as there is no remote way to alter it. To change it on your computer, try opening regedit and adding the RecieveTimeout DWORD with a Value of (#of minutes)*6000. Hope this helps-CodeKid1001
Edit: Sorry about that, I forgot to put in the file path:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings
I used something similar to laod HD pictures as a background using ASP Pages
But i used jQuery to handle the images and its loading. This is a sample for 1 image but with a bit of tweaking you can load dynamically
myImage = new Image();
$(myImage).load(function ()
{
$(this).hide(); //Stops the loading effect of large images. can be removed
$('.csBackground li').append(this); //Append image to where you need it
$(myImage).show();
}).attr('src', settings.images[0]) //I pass an array from ASP code behind so 0 can be 'i'
.error( function { checkImages(); } ) //try and relaod the image or something?
So instead of changing the timeout- just try and reload the images on error.
Otherwise i only found a solution that is client specific (HTTP Timeout)
