In developing a website, I have a section structured like so:
<ul id="preview-tabs" class="row nav nav-tabs">
<li>Main</li>
<li>Alternative 1</li>
<li>Alternative 2</li>
</ul>
With corresponding CSS:
#preview-tabs {
border-bottom: 1px solid #8E9753;
}
And finally the Javascript:
$('#preview-tabs a').click(function (e) {
e.preventDefault();
$(this).tab('show');
});
Now somewhere along the way I might need to change the ID of the UL to something like design-tabs and would have to remember to update the corresponding CSS and Javascript to maintain the functionality.
My question: is there a tool that keeps track of this relationship and can either
1) Alert me that some linked code needs to be updated OR
2) Do the update of the code automatically. Sort of like the Refactor feature for Java in Netbeans
Not that I know of though what you could do so that if you did update it then you wouldn't need to change your css is you could add a class to it instead of an id then target the element that way.
you should use ctlr+shift+R to replace a selected with another text.

I have this menu:
What I want to do: when I click the image button on the right (#sub-menu) I want it to open the sub-menu (.sports2).
this is a sub-item html code for an example:
<a href="#"><li> Golf
<img src="strokesmenu.png" id="sub-menu" />
<ul class="sports2">
<li>British Open</li>
<li>Masters</li>
<li>PGA Championship</li>
<li>US Open</li>
</ul>
</li></a>
Why this code isn't working for me?
$('#sub-menu').click(function(){
//$('.sports2').slideToggle("slow");
$(this).find('ul>li').slideToggle(slow);
})
first of all, <li>British Open</li> this structuring is so wrong I cannot even describe it how wrong it is.
convert it to the <li>British Open</li> if you want to make click-able while li try using below css or similar to that
ul li a {
display: inline-block;
width:100%;
height:100%;
}
also there must be only one item with one id having multiple item is against the W3C rules and clicking the little icon is not so user friendly. so instead give class to main item li and hanle the click with that one.
$('li.main').click(function(){
$(this).find('ul').slideToggle('slow');
})
apparently you cannot do that so you have to bind it to the img first change id to the class e.g. class="sub-menu"
$('li img.sub-menu').click(function(){
//$(this) -> img .next() -> ul
$(this).next().slideToggle('slow');
})
now the $(this).find('ul>li').slideToggle('slow'); should work but it will open every li and might cause some problem issues.
instead I suggest using $(this).find('ul').slideToggle('slow'); so the list can be opened/closed. you see the animation differences by trying it and choose the best one for you.
EDIT FOR CLICK BUG:
well not sure if I get it right but as I understand in some cases you need to redirect the page in others open the sub menu.
in that case you can check if the li has submenu or not the following code should do the trick.
$('li.main').click(function(){
if ($(this).has("ul")) // if has submenu
$(this).find('ul>li').slideToggle('slow');
else
// your redirect code.
})
I'm using wordpress 3.5 and create menu with submenus. It's structured like this:
<ul class="menu">
<li id="menu1">Menu 1</li>
<li id="menu2">Menu 2</li>
<li id="menu3" style="z-index:100;">
Menu 3
<ul class="submenu">
<li id="submenu1">submenu1</li>
<li id="submenu2">submenu2</li>
<li id="submenu3">submenu3</li>
</ul>
</li>
</ul>
The problem is the menu with submenus, it's automatically attached a z-index with value 100. I don't want it to be like that because it gives me trouble on adding lavalamp effect to those menus.
I tried to edit the z-index by using jquery just after the menu is created using wp_nav_menus simply like this:
jQuery(document).ready(function(){
jQuery("#menu3").css("z-index", "0");
});
But unfortunately, it doesn't work. How can I remove that inline css style?
Use the removeAttribute method, if you want to delete all the inline style you added manually with javascript.
element.removeAttribute("style")
Reset z-index to initial value
You could simply reset the z-index to it's initial value causing it to behave just like the li would without the style declaration:
$(function(){
$('#menu3').css('z-index', 'auto');
});
You can go vanilla and use plain javascript (code should run after your menu html has loaded):
// If you're going for just one item
document.querySelector('#menu3').style.zIndex = 'auto';
Remove style attr
You could use jQuery to remove the style attributes from all your list:
Note: Keep in mind this will remove all styles that have been set to your element using the style attribute.
$(function(){
$('#menu3').removeAttr('style');
});
Or vanilla:
// Vanilla
document.querySelector('#menu3').style = '';
If you want remove all inline styles, Pranay's answer is correct:
$("#elementid").removeAttr("style")
If you want to remove just one style property, say z-index, then you set it to an empty value:
$("#elementid").css("zIndex","")
From the jQuery documentation (http://api.jquery.com/css/):
Setting the value of a style property to an empty string — e.g. $('#mydiv').css('color', '') — removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's .css() method, or through direct DOM manipulation of the style property.
This is what I consider a better approach because it only removes the z-index style instead of the whole style attribute. Here is a working Fiddle.
//As commented by #DA this is enough
$("#elementid").css("zIndex","")
//this could be useful in another situation so I will leave it :)
$(document).ready(function () {
$('#menu3').attr('style', function(i, style){
return style.replace(/\z-index\b[^;]+;?/g, '');
});
});
Hope it helps.
I am having very specific case where I needed to split the data into two different lists in html. Like this:
<ul id="first_list">
<li ref="1">The quick brown</li>
<li ref="2">My father works</li>
</ul>
And the second list is like:
<ul id="second_list">
<li ref="1">jumps over the lazy dog</li>
<li ref="2">at the Ministry of Defense</li>
</ul>
So as you can see I from the "ref" attribute I know which <li> element from the second list is a continuation of which <li> element from the fist list.
Now I need to enable the jQuery UI sortable() to those lists but when I reorder the first I need the second reordered too. I tried using handle but it doesn't works because it looks like the handle element needs to be inside the element which is moved but these two are at a different places in the page.
I do believe that you should have shared some of your code (what you've tried), and I'm assuming you are familiar with Sortable plugin that you are using. You should run the below code on success event of Sortable so as soon as you sort any LI, the other list will be sorted too. Anyways,
Try this:
//This line stored the LIs in a temp variable and remove it
var $cachedList = $('<div />').html($('#second_list').html());
$('#second_list > li').remove();
//This line loads up the first UL's LIs and replaces the content for each LI
//using $cachedList.
$('#second_list').html($('#first_list').html()).find('li').each(function () {
$(this).html($cachedList.find('li[ref="'+$(this).attr('ref')+'"]').html());
});

I have built a simple dropdown list which I populate with various links. It contains about 50 items, so I wrapped it in a div to make it scrollable. Problem is, when I mouseout, I lose the whole list, unless the first two list elelments are showing. I have constructed this dropdown as a submenu, with the first two links as the 'container' of sorts.
I somewhat understand why I am losing the entire list, but can't figure out how to make the top links reapear on mouseout.
$('.myMenu > li').bind('mouseover', openSubMenu);
function openSubMenu() {
$('.myMenu').css('overflow','auto');
$('.myMenu').css('height','400px');
$('.ulMenu').css('visibility', 'visible');
};
$('.myMenu > li').bind('mouseout', closeSubMenu);
function closeSubMenu() {
$('.myMenu').css('overflow','hidden');
$('.myMenu').css('height','20px');
$('.ulMenu').css('visibility', 'hidden');
}
}
</script>
<div id="menu">
<ul class="myMenu">
<li id="li_left"> Application </li>
<li id="li"> Hover For Listing
<ul id="tasksUl" class="ulMenu">
</ul>
</li>
</ul>
</div>
I think you also have to post your .css for the list. I think you got a menu and you wanna open a list on hovering <li id="li"> Hover For Listing
You are setting a
$('.myMenu').css('height','20px');
and I don't get why you would do that. Also your .css styles are pretty much deprecated.
Check the fiddle here: http://jsfiddle.net/eR2y9/1/
Works like a charm. There is no need for you to add a height for the menu because it's dynamically adjusting depending on the amount of entries inside. Also if set to display none it's not taking any space away.. If you have further questions or if I misunderstood your problem feel free to reply to my post and I will find a solution for ya.
I'm sure this will be a simple question but I still struggle with DOM selectors in Jquery so here is a model of my html code:
<fieldset class="product-options" id="product-options-wrapper">
<ul class="options-list">
<li><a href>Item1.1</a></li>
<li><a href>Item1.2</a></li>
<li><a href>Item1.3</a></li>
</ul>
...other html items here
<ul class="options-list">
<li><a href>Item2.1</a></li>
<li><a href>Item2.2</a></li>
<li><a href>Item2.3</a></li>
</ul>
</fieldset>
Now how do I select all of the 'li a' items in both lists (or X number of lists) with class name .options-list and bind them with a click function.
Currently I have:
$('fieldset#product-options-wrapper ul.options-list > li a').bind('click', function(e) {
//code here
});
And it only gets the first options-list.
Thanks, greatly appreciated!
EDIT: If i click on a Item2.X list item first, then it will grab that options list. But as soon as I click on the Item1.x list items it disregards the second .options-list
If you are going to bind to each li element, you should bind it to the ul element instead (helps greatly with performance when there are a lot of events).
$('.options-list', '#product-options-wrapper').bind('click', function(e)
{
e.preventDefault();//In case you don't want to go to a different page
var clicked = e.target;//The href that was clicked
/* If you only want this to happen if the a tag was clicked, add the following line
if(clicked.tagName == 'A')*/
//Rest here
});
How about $('.options-list a').bind('click', function(e) { });?
You can use delegate in this case to make it even simpler. Try this
$('#product-options-wrapper ul.options-list').delegate('li > a', 'click', function(e) {
//code here
});
Your method seems sound to me. I created a test fiddle using your HTML (and an extra anchor to prove that it won't get the click added) and your JS (with minor modifications).
http://jsfiddle.net/chrisvenus/esZxH/1/
The selector you had did work but since you said you wanted the a to be a direct child of the li (or at least I read it that way) I slightly tweaked it in my version above. ARe you sure its not just your function is not doing quite what you want while executing or can you confirm that your click function isn't being run at all?
