I've got a menu like:
<ul class="sub">
<li>New</li>
<li>Open</li>
<li>Save</li>
<li>Help</li>
</ul>
which is "animated" via css hover code (nothing special). The Open option kicks off a file open function (via a hidden "input type=file" control). That all works fine, but when I'm done with the "file open" dialog, the menu is still displayed (albeit briefly). Is there any way to have the menu disappear as soon as "Open" is clicked, and have that (disappearance) render on the screen even before the "open dialog" runs?
TIA
What you want to do is hide the submenu when the window blurs. Not sure if you're using a JS library, but it would simply be like below. Here's a generic jsfiddle: http://jsfiddle.net/rgthree/b6QSP/
window.onblur = function(){
// Where "submenu" is the sub menu to hide,
// however you're targeting it
submenu.style.display = 'none';
}
Add a click event listener for the 'Open' option:
var openLink = document.getElementById('open'); // replace 'open' with element's ID
openLink.addEventListener('click', clickHandler, false);
function clickHandler() {
var submenu = document.getElementById('submenu'); // replace 'submenu' with submenu's ID
submenu.style.display = 'none';
}

I'm using angular-foundation and trying to find a way to change the off-canvas menu icon when you open/close the menu. Currently I use:
<a class="right-off-canvas-toggle menu-icon"><span></span></a>
I'd like to replace the "menu-icon" with my own class, but I'm not sure how to hook into the close method. I tried adding an ng-click, but that won't fire on the close since an <a> tag is used to overlay the rest of the page for the close function. I figured based on that, using the off canvas would be the best method.
You can do so hooking into the open.fndtn.offcanvas and close.fndtn.offcanvas events, something like this:
$(document).on('open.fndtn.offcanvas', '[data-offcanvas]', function() {
var off_canvas_icon = $(this).find('.right-off-canvas-toggle');
off_canvas_icon.removeClass('menu-icon').addClass('close-icon');
});
$(document).on('close.fndtn.offcanvas', '[data-offcanvas]', function() {
var off_canvas_icon = $(this).find('.right-off-canvas-toggle');
off_canvas_icon.removeClass('close-icon').addClass('menu-icon');
});
I have a bootstrap page that lists items in a table. Each item has its own delete link that launches the modal.
<a href="#modalDel" data-idtodelete="<?php echo $value->id; ?>" class="deletelink">
Delete this item
</a>
...
jQuery("a.deletelink").click(function(event){
var id2del = $(this).data('idtodelete');
jQuery("#myModalLabel").html("Delete item: "+id2del); //works great
jQuery('#modalDel').modal('show');
});
I can pass data to the modal easily, but now I have to make the main button in modal to reflect the dynamic url and call to it (only) when this button is clicked
Any ideas? Thanks
PS: cannot use the hidden event for this, because modal can also be hidden with the cancel button. Also, modal should be closed after/before calling the dyn. delete url of main button
I'll hazard a guess at this. Haven't tested because I'm not really sure about the setup.
var $ = jQuery; // using as a shortcut
$('#modalDel').on('show',
function() {
// Composes delete URL with arguments
var dynUrl = composeUrl(args);
// assuming the modal button is an anchor element
$('#modalButton').attr('href', dynUrl);
// Also closes the modal box after being clicked
$('#modalButton').on('click',
function(e) {
$('#modalDel').modal('hide');
});
});
JScript
// Wait for the page and all the DOM to be fully loaded
$('body').ready(function() {
// Add the 'hover' event listener to our drop down class
$('.dropdown').hover(function() {
// When the event is triggered, grab the current element 'this' and
if ($(this).find('.sub_navigation').is(":visible")) {
// find it's children '.sub_navigation' and display/hide them
$(this).find('.sub_navigation').slideUp();
} else {
$(this).find('.sub_navigation').slideDown();
}
});
});
First of all here is the fiddle //
http://jsfiddle.net/Hv2HZ/
I am using wordpress to create my site...
(if that matters)
Someone helped me get the drop-down menu to work better.
But ever since I added the new JQuery script the link doesn't even work.
I tried hovering over it but no menu dropped.
When I hover on the fiddle it works.
Why is this?
And how can I fix this?! :(
How to disable/enable a button? which is not in a form , in a navBar. I'v tried some examples , all fail.
I'm changing my textarea text $("textarea").val(x); The text is changing , the problem it doesn't get auto re-size , I see the ugly scroll bar on the side , If I manually resize it , its OK... is there a method to force refresh or something like that?
Thanks
Update (TextArea):
If i click on the text area and then press any key -> it opens up as should be,
I'm trying to simulate it .. but fail , the binding is works , but the trigger for keypress/keydown doesn't , I tried some codes from googling, this should work , I think , mayb for nomral jQuery 1.6 , but not jQuery mobile.. My test are are on Chrome and iPhone 4
$('#textarea').bind('click', function() {
var e = jQuery.Event("keypress", { keyCode: 64 });
$(this).trigger( e );
});
UPDATE:
Link button example:
http://jsfiddle.net/gRLYQ/6/
http://jsfiddle.net/gRLYQ/7/ (Header button example)
JS
var clicked = false;
$('#myButton').click(function() {
if(clicked === false) {
$(this).addClass('ui-disabled');
clicked = true;
alert('Button is now disabled');
}
});
$('#enableButton').click(function() {
$('#myButton').removeClass('ui-disabled');
clicked = false;
});
HTML
<div data-role="page" id="home">
<div data-role="content">
Click button
Enable button
</div>
</div>

Links styled like buttons have all the same visual options as true
form-based buttons below, but there are a few important differences.
Link-based buttons aren't part of the button plugin and only just use
the underlying buttonMarkup plugin to generate the button styles so
the form button methods (enable, disable, refresh) aren't supported.
If you need to disable a link-based button (or any element), it's
possible to apply the disabled class ui-disabled yourself with
JavaScript to achieve the same effect.
Regarding your second question, you can cause a textarea to autogrow by triggering a keyup() event on it.
Considering your original example code, the following works for me:
/*Note: I'm using 'on' instead of 'bind', because that's what I've actually tested
with, but I'm pretty sure this will work with 'bind' as well*/
$('#textarea').on('click', function() {
//First we'll add some text to #textarea
$('#textarea').val('some dummy text to be added to the textarea');
//Then we trigger keyup(), which causes the textarea to grow to fit the text
$('#textarea').keyup();
});
Short and sweet version of the above, this time chained and with no comments:
$('#textarea').on('click', function() {
$(this).val('some dummy text to be added to the textarea').keyup();
});
Adapted from here.
I use a ASP.NET Menu control with Orientation=Horizontal. It is kind of irritating that the popout menus appear on mouseover, which causes it to show by accident if you move the mouse over the menu when you want to click on something right below the menu. Then the menu popout hides the element you actually wanted to click on!
Is it possible to change the functionality so that the popout requires a mouse click instead of mouseover?
Well, I found a solution myself (kind of a hack...).
This solution requires use of AJAX to capture the menu item onclick postback event, so it can be picked up client side in javascript before doing the actual postback when you click the menu item.
First, I override these functions that is defined by the Menu control
to ignore the menu popout in the mouseover event:
var activeMenuItem = null;
function Menu_HoverStatic(item) {
// Register the active item to be able to access it from AJAX
// initialize postback event
activeMenuItem = item
// Apply the style formatting on mouseover (colors etc).
// This was also called in the original Menu_HoverStatic function.
Menu_HoverRoot(item);
}
function Menu_Unhover(item) {
activeMenuItem = null; // This is the only difference to the original
var node = (item.tagName.toLowerCase() == "td") ?
item:
item.cells[0];
var nodeTable = WebForm_GetElementByTagName(node, "table");
if (nodeTable.hoverClass) {
WebForm_RemoveClassName(nodeTable, nodeTable.hoverClass);
}
node = nodeTable.rows[0].cells[0].childNodes[0];
if (node.hoverHyperLinkClass) {
WebForm_RemoveClassName(node, node.hoverHyperLinkClass);
}
Menu_Collapse(node);
}
// Then I added a renamed copy of the original `Menu_HoverStatic` function:
function Menu_ClickStatic() {
// Pick up the active menu item that is set in the
// overridden Menu_HoverStatic function.
// In the original, the item was input parameter.
var item = activeMenuItem;
// The rest is identical to the original Menu_HoverStatic.
var node = Menu_HoverRoot(item);
var data = Menu_GetData(item);
if (!data) return;
__disappearAfter = data.disappearAfter;
Menu_Expand(node, data.horizontalOffset, data.verticalOffset);
}
Then I snap up the onclick postback event in AJAX that is triggered by the menu. This must be done to cancel the onclick postback and display the menu popout instead.
// Get the Page Request Manager that provides all the .NET
var prm = Sys.WebForms.PageRequestManager.getInstance();
// Register postback event for asyncronous AJAX postbacks
if (prm) prm.add_initializeRequest(InitializePostback);
function InitializePostback(sender, args) {
var element = args.get_postBackElement();
//Check if the postback element is the menu
if (element.id == 'myMenu') {
// Name of the menu element that triggered is the postback argument
var postbackArguments = document.getElementById('__EVENTARGUMENT');
if (postbackArguments)
// Check on the menu item name to pick up only the menu items that shall
// trigger the popout (not the items that does an actual command).
if (postbackArguments.value == 'MenuTopItem1'
|| postbackArguments.value == 'MenuTopItem2'
|| postbackArguments.value == 'MenuTopItem3') {
// Abort and cancel the postback
prm.abortPostBack();
args.set_cancel(true);
Menu_ClickStatic(); // Call my own copy of the original function
return;
}
}
}
Note:
I found out the details about these functions by using the script viewer in Firebug.
The soluton provided above doesn't work in everone's case. One can also try this out, it worked in my solution-
var jq = jQuery.noConflict();
jq(document).ready(function () {
jq(document).on('click', '#ctl_id_Here', function () {
Menu_HoverStatic(this);
Menu_HoverRoot(this);
});
jq(document).on('click', '#ctl_id_Here', function () {
Menu_HoverStatic(this);
Menu_HoverRoot(this);
});
});
3 Steps:
Stop the current hovering effects:
On page load (or on ready), write following line: $('#Menu1').find('ul .level2').css('display','none');
Once you do that, it'll stop the hovering effect of that menu. But once you do that, then you would only be able to open the submenu by making it display block, so for that I wrote following lines, onclick of an image inside the menu: $('#Menu1').find('ul .level2').css('display','block');
Open the menu on click of an element: I don't think need to explain it. Just make menu display block on click of the identified element.
Close the opened menu: 2 ways to do it: First; Use property Disapperafter as below:
Second: Write below code to close it onclick of anywhere else on the screen:
$('body').click(function(evnt) {
if($(evnt.target).parents('table#menu').length == 0)
{
$('#MenuInvitePatient').find('ul .level2').css('display','none');
return;
}
else
{
return;
}
});
