I've got:
<th>First Name<span class="ui-icon ui-icon-arrowthick-1-s"></span></th>
When the user clicks on a th cell, I need to clear the span tag from every one of it's siblings.
$('th').click(function() {
var $th = $(this);
$th.siblings().each
Your question isn't very clear -- your title says remove the class, but your post says you need to clear the span tag? To remove the class you would use removeClass() in your each block. Otherwise to remove the entire tag you could use remove().
Edit
You could try this:
$('th').click(function() {
var $th = $(this);
$th.siblings().each(function() {
$('span').remove();
}
});

Im trying to use pass my car value to another function, which i have no idea how. i tried to place the whole function btn-info-add into .span8. But this it will execute twice on the 2nd time.
$(".span8").on("click", "table #trID", function() {
var car = ($(this).closest("tr").children("td").eq(1).html());
$('#myModal1').modal('show');
});
$("#btn-info-add").click(function() //button inside the modal
selectCourse(car); //execute ajax
});
var car; //car must be declared out of your function to be available for both functions
$(".span8").on("click", "table #trID", function() {
car = ($(this).closest("tr").children("td").eq(1).html());
$('#myModal1').modal('show');
});
$("#btn-info-add").click(function() //button inside the modal
selectCourse(car); //execute ajax
});
You can create a hidden element inside your dialog (input would be great) and assign it your desire value.
<div id="dialog" title="Basic dialog">
<p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
<input id="carvalue" type="hidden" value=""/>
</div>
Note that I created an input element (hidden, of course) which is going to store the value that I want to access later. After that, you can modify your code like this:
$(".span8").on("click", "table #trID", function() {
var car = ($(this).closest("tr").children("td").eq(1).html());
$("#carvalue").val(car); // Store value into hidden input
$('#myModal1').modal('show');
});
$("#btn-info-add").click(function() //button inside the modal
var car = $("#carvalue").val(); // retrieve value from input hidden
if(car != ""){
selectCourse(car);
}
});
This technique is commonly used in forms to pass additional information on AJAX calls. Your user will not notice its presence and you can keep working. Happy coding!
EDIT:
JQuery has a method called jQuery.data to store information into JQuery elements. So your values are going to be stored on the element itself. Your code will look like this:
$(".span8").on("click", "table #trID", function() {
var car = ($(this).closest("tr").children("td").eq(1).html());
jQuery.data("#btn-info-add", "car", car); // store data inside jQuery element
$('#myModal1').modal('show');
});
$("#btn-info-add").click(function() //button inside the modal
selectCourse(jQuery.data("#btn-info-add", "car")); //execute ajax
});
I hope it helps you. Happy coding!
Given a certain event (say, a button click), I'd like to disable Chosen.js for a specific select box.
Is this possible?
I had a similar requirement although it didn't require a button click, I just wanted to enable / disable Chosen for specific select boxes.
My solution is for each select element that you don't want to use Chosen with, add the CSS class 'no-chzn'. Then in chosen.jquery.js, add the following lines to the constructor (this is near line 533 in version 1.1.0):
$.fn.extend({
chosen: function(options) {
if (!AbstractChosen.browser_is_supported()) {
return this;
}
return this.each(function(input_field) {
var $this, chosen;
$this = $(this);
if ($this.parent().hasClass("chosen-disable")) { return; } // Just add this line!
chosen = $this.data('chosen');
if (options === 'destroy' && chosen) {
chosen.destroy();
} else if (!chosen) {
$this.data('chosen', new Chosen(this, options));
}
});
}
});
For example you have a select with class no-chosen and you do this:
$("select:not('.no-chosen')").chosen();
It means it takes all selects except the one with no-chosen class.
I have problem on my webpage,
I am adding an element in the document when the user clicks on a specific button.
the element is
<div class="draggableResizable">
Some text
</div>
script.js
$('#button').click(function() {
$("#pageWrap").append(element)
})
$('.draggableResizable').draggable().resizable()
Any suggestions are welcome.
Thank you.
Just restructure so you initialize the widgets after adding the element:
$('#button').click(function() {
//create an element
var $element = $('<div class="draggableResizable" />').text('some text');
//append it to the DOM
$("#pageWrap").append($element);
//make it "draggable" and "resizable"
$element.draggable().resizable();
});
Here is a demo: http://jsfiddle.net/ZSgBP/1/
You need to use the .on() or .live() function if you want to add events to an object after adding it to the DOM. If you don't want to use either of these functions, you can simply add the div to the HTML, then hide it on page load and call .show() on it.
I have a problem in my KnockoutJS application that I can't seem to figure out. Basically, I've bound a list to a 'ko.computed' method which allows me to filter items from the main list. I use this list for my main display to the user. On each item in my template, I have one ore more buttons that I need to render as JqueryUI buttons. I can't seem to find the way to redraw the buttons correctly in my model once the computed triggers a change.
Here is a very (very) simple example of a mock view model:
function List(items) {
var self = this;
self.allItems = ko.observableArray(items || []);
self.search = ko.observable('');
self.filtered = ko.computed(function(){
var search = self.search();
return ko.utils.arrayFilter(self.allItems(), function(item){
return item == search;
});
});
}
My view might look like this:
Search: <input type='text' data-bind='value: search' />
<ul data-bind='foreach: filtered'>
<li>
<span data-bind='text: $data'> </span>
<button>NOTICE</button>
</li>
</ul>
And here is how I initialize the display:
$(function(){
var vm = new List(['a', 'b', 'c', 'd', 'e', 'f', 'g']);
ko.applyBindings(vm);
$('button').button(); // <-- notice!
});
Note that everything works fine initially! I get the nice looking JqueryUI button when the page first displays... However, as soon as I enter a into the search box, the button loses it's style completely. I need to find a way to call $('button').button() again.
Is there an event or callback inside of Knockout.js that I could call to setup my ui buttons after the computed method is triggered?
Thanks in advance!
The reason the style is getting reset is because the dom element that the button was previously bound to has been destroyed.
You can solve this by creating a simple custom binding (not-tested)
ko.bindingHandlers.uibutton = {
init: function(element, valueAccessor) {
var $element = $(element), config = valueAccessor();
$element.button();
}
}
This can be added to your template with this addition
<button data-bind="uibutton: {}">NOTICE</button>
You can remove the call to $('button').button();
When using KO we can almost do without standard Jquery expressions altogether, often custom bindings allow us to do the same but with the possibility of more advanced things like reacting to observables etc.
Hope this helps
I have the following scenario:
I have a button\link with a image inside like this:
<button type="submit" id="myButton" class="button"><img src="../../Content/images/check.png" id="defaultImage" />
SaveData!!!</button>
We are OK here! Now what I need to do is:
I want on the click that the image change for a loading element that is previously loaded in the page like this:
<img id="loadingImage" src="../../Content/images/loader.gif" style="display: none;" alt="loading"/>
And then when the load complete turn back the old button image, I ended with this code:
function loader() {
var $button = $('#myButton');
if (btnState == '1') {
$button.find('img').hide();
$button.prepend($('#loadingImage'));
$('#loadingImage').css({ 'display': 'inherit' });
btnState = '0';
}
else {
$button.find('img').hide();
$button.prepend($('#defaultImage'));
$('#defaultImage').show();
btnState = '1';
}
}
This does the trick for ONE SINGLE button(since I pass its ID in the function) but, when I have for example a grid with a button on each line, I found inviable when managing a screen with many buttons do this for each of then. The main question is: How can I make this method general for all buttons/links on one specific class in the page?
The goal is: Click a button, get the image and change it and stop(can be manual). I just don't wanna have to Hook ALL buttons.
You should do something like this, it will prevent the user from double submitting:
$('.button').click(function(evt) {
evt.preventDefault();
var button = this;
hideButton(button);
$('ID or CLASS').load('AJAX FILE URL', function() {
//On success, show button remove image
showButton(button);
});
});
function hideButton(button) {
$(button).hide().after('<img src="../../Content/images/loader.gif" alt="loading"/>');
}
function showButton(button) {
$(button).next('img').hide();
$(button).show();
}
All of the code above should be in the $(document).load
Your HTML should look like:
<button type="submit" class="button"><img src="../../Content/images/check.png" />SaveData!!!</button>
There is no need for Id's now on anything.
