I'm having trouble displaying hidden inline content within a jQuery UI tooltip widget. Here's what I have so far:
$("a.tooltip").tooltip({
content: function() {
$('table').show();
return $('table');
}
});
The table in question is set to not display by default. The above code shows the table in the tooltip, however, if I hover off the link that activates the tooltip, and return to it, an empty tooltip displays, without my inline content. I suspect I want to invoke the destroy() method when mousing off the tooltip, but not sure where to put that exactly.
you need to rebind the content
$("a.tooltip").on('mouseenter', '.sourceItem', function(){
$(this).find('.table').show();
}).on('mouseleave', '.sourceItem', function(){
$('.tooltip').hide();
});
use jQuery which uses on functionality.place this in the ready event.

I have a web application created in asp.net. In which, I would like to show a div (which is hidden initially) when a button is clicked with a css transition.
Additional Request:
The div that is shown on button click, will have some content added to it dynamically at run time.
How this can be done?
Here is a variation of the script from #geevee which I tend to use a lot, the DIV will slide up or down with a close and open option. Note the 500 is the speed of execution in milliseonds, you can change that to what ever suits you.
$(function(){
$('#BUTTON_ID').click(function(){
if ($('#DIV_ID').css('display') =='none')
{
$('#BUTTON_ID').html('Show DIV');
$('#DIV_ID').slideDown(500);
}
else
{
$('#BUTTON_ID').html('Hide DIV');
$('#DIV_ID').slideUp(500);
}
});//end .click
});//end onload
Hope this helps
Plain Javascript:
document.getElementById('BUTTON_ID').addEventListener('click', function(){
document.getElementById('DIV_ID').style.display = 'block';
})
Alternatively, with jQuery:
$(function(){
$('#BUTTON_ID').click(function(){ $('#DIV_ID').show() });
});
replace BUTTON_ID and DIV_ID with real element IDs.
UPDATE:
if you want the div to be shown with transition, i'd recommend to use jQuery as following:
$(function(){
$('#BUTTON_ID').click(function(){ $('#DIV_ID').fadeIn() });
});
notice the .fadeIn() method, which can be replaced with .show(), .slideDown() and more. jQuery is fun.
UPDATE 2:
in order to inject dynamic content into the div, do as following:
$(function(){
$('#BUTTON_ID').click(function(){
$('#DIV_ID').html('<b>Hello, dynamic content!</b>');
$('#DIV_ID').fadeIn();
});
});
hope that helps.
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?! :(
I am trying to insert a button into HtmlEditor's ToolBar. Button should get selected text by mouse or keyboard and add '#' character at the start of that selected text for locating it as a url.
As i understand the best solution is creating a plugin for adding buttons into html editor toolbar. I found creation codes but the problem is; how can i get selected text? Ext-js version 2.2
And there is the code that provides to create a plugin for html editor toolbar button:
Ext.ns('Ext.ux.form.HtmlEditor');
Ext.ux.form.HtmlEditor.NewLine = Ext.extend(Ext.util.Observable, {
init:function (cmp) {
this.cmp = cmp;
this.cmp.on('render', this.onRender, this);
},
onRender:function () {
this.cmp.getToolbar().addButton([
{
iconCls:'newline', //your iconCls here
handler:function () {
this.cmp.insertAtCursor('<br> ');
},
scope:this
}
]);
}
});
You can get the selected text like this: window.getSelection()
That gives you a Selection object. If you want to get the text only: window.getSelection().toString()
but if you want to make stuff bold or something, you need to check if the selection is inside the editor. Everything you need for that is inside the selection object.
=> correction: the htmlEditor uses an iframe you can get the iframe window by the getWin function.
Note that this is only for modern browser (not < IE9) judging from the legacy Ext version you use, that might be an issue for you... but there are workarounds for IE.

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>
NOTE: - http://jquerymobile.com/demos/1.0rc2/docs/buttons/buttons-types.html
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 want to show a loading image before the content of the whole page is loaded. How to achieve this? I'm working in ASP.NET.
Thank you.

You would need to use Javascript to accomplish this. My preference is jQuery. jQuery has a function that executes when the page is fully loaded, so you could set your main content div to have a css property display:none, and then when the DOM is ready, you could use jQuery to show the content:
$(document).ready(function() {
$("#myContent").css("display", "block");
});
You should initially have the image showing in your HTML, and then hide it when the page loads, like this:
Javascript:
window.onload = function() {
document.getElementById('loadingImageIDHere').style.display = 'none';
};
EDIT: The OP tagged this question as 'javascript', NOT 'jquery'!!
My personal preference is to have a loading image displayed on every page in advance and then use jQuery to hide the image once the page has loaded. It's up to you whether you want to use $(document).ready or $(window).load.
// assumes you already have a DIV#preloader container on your page centered with a loading image inside
// of it
$(document).ready(function() {
$("#preloader").hide();
});
$(window).load(function() {
$("#preloader").hide();
});
