Very simply put : the line c开发者_C百科urrentItem.toggleClass('open');
doesn't seem to work.
More precisely, when inspecting the results with firebug, I can see the class "open" flashing (appearing and immediately disappearing) on the relevant element. So it's like the function is actually triggered twice (of course I only click once).
Can somebody explain me why this is and how to prevent it?
Here is my jQuery code :
$('div.collapse ul.radio_list li input[type=radio]').click(function (event) {
var currentTree = $(this).parent().parent().parent();
var currentItem = $(this).parent().parent();
var currentGroup = currentItem.attr('rel');
$(this).parents('ul').children('li').removeClass('select');
if ($(this).is(':checked')) {
currentItem.addClass('select');
}
currentItem.toggleClass('open');
var currentLevel = 0;
if (currentItem.is('.level1')) {currentLevel = 1;}
if (currentItem.is('.level2')) {currentLevel = 2;}
if (currentItem.is('.level3')) {currentLevel = 3;}
var nextLevel = currentLevel + 1;
currentTree.children('li').filter('li[rel ^=' + currentGroup + '].level' + nextLevel).animate({'height': 'show', 'opacity': 'show'}, 250).addClass('currentChild');
});
And here is a part of my HTML code, slightly simplified for better readability (not very pretty I know, but I only have a limited control on the HTML output) :
<div class="col_left collapse">
<ul class="radio_list" rel="7">
<li class="onglet level0" rel="group1">
<span class="onglet level0">
<input type="radio" />
<label>Services Pratiques</label></span>
<input type="hidden" value="1">
</li>
Thanks in advance.
Problem solved: the JS file was actually included twice in the HTML head, which caused the function to be triggered twice with each click.
I had a similar problem on my site, and I found that I had accidently duplicated the toggleclass hook all the way at the bottom, when first messing around with it. Oops! Make sure to look for double calls!
I had a similar problem doing this:
html:
<a>JS-link</a>
js:
$('a').click(function(event) {
... my stuff ...
# Forgot to do event.preventDefault(); !!
}
results in clicks being register twice!
I had the same issue and realized I had accidentally bound the function twice. I had originally meant to move the code from one javascript file to another but accidentally left the original in its place.
