I am trying to parse a web page with JavaScript targeting list <li> without class.
<ul id="cartItems">
<li class="heading">
<li>...</li>
<li>...</li>
<li>...</li>
<li>...</li>
</ul>
Use querySelectorAll to get all li elements without a class.
var liWithoutClass = document.querySelectorAll('#cartItems > li:not([class])');
console.log(liWithoutClass);
document.write(liWithoutClass[0].textContent); // Output the first li
document.write('<br />' + liWithoutClass[3].textContent); // Output the last li
<ul id="cartItems">
<li class="heading">Heading</li>
<li>Element 1</li>
<li>Element 2</li>
<li>Element 3</li>
<li>Element 4</li>
</ul>
var elems = document.querySelector(".heading");
console.log(elems);
//Now we strip the class out like this:
elems.setAttribute(class, "none");
//Now we display the updated values below
console.log(elems);
// This won't work in Stack's editor, so you'll have to validate it against the page you want.
//Now, just grab the entire element by id from the page as below:
var updatedContent = document.getElementById("cartItems");
console.log(updatedContent);
//Again, stack's editor is limited, but overall this should work fine on your page.
<ul id="cartItems">
<li class="heading">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
<li>item 4</li>
</ul>

I have a menu in Wordpress that uses WP Menu system. All links are basically custom links that output the following (WP classes removed for brevity):
<ul>
<li>About
<ul>
<li>Section 1</li>
<li>Section 2</li>
<li>Section 3</li>
</ul>
</li>
<li>Services
<ul>
<li>Section 1</li>
<li>Section 2</li>
<li>Section 3</li>
<li>Section 4</li>
</ul>
</li>
</ul>
I'm trying to remove the domain part of the URL if the parent page is being viewed so if I were viewing the About page the links in the menu would change to:
<li>About
<ul>
<li>Section 1</li>
<li>Section 2</li>
<li>Section 3</li>
</ul>
</li>
<li>Services
<ul>
<li>Section 1</li>
<li>Section 2</li>
<li>Section 3</li>
<li>Section 4</li>
</ul>
</li>
</ul>
The problem I have with jQuery is that I cannot target each specific page because the pages will be unknown, I therefore need it to get the URL and match it with the correct part of the menu to change the links. I have tried this but its too specific:
if (window.location.href.indexOf("about") != -1) {
//do something
} else {
//do something else
}
EDIT
I only want to alter the links in the menu for the current page. The answers so far change all of the link in the menu, I just want to target the links found on the same page.
DEMO here
Firstly add a class sections to the ul element to make it easy to target.
<ul class="sections">
<li>Section 1
</li>
<li>Section 2
</li>
<li>Section 3
</li>
</ul>
Use .map() to replace the href for each anchor.
EDIT - based on your new update & I liked #Archer's update too. This should work.
$(".sections a[href* = '" + window.location.pathname + "/#']").map(function(){
var currentsection = this.href.split('/').pop();
this.href = currentsection;
});
Another option...
$(function() {
$("a[href*='" + window.location.pathname + "#']").attr("href", function() {
return "#" + this.href.split("#")[1];
});
});
This will find all the links with the current page and a # in them and fix the href value accordingly.
Try this,
$('a').each(function(){
// check the anchor tab href has location.href or not
if($(this).attr('href').indexOf(window.location.href) != -1)
{
// some code to replace location.href to blank
var href=$(this).attr('href').replace(window.location.href,'');
$(this).attr('href',href);
}
});
Alternatively, try this,
$('a').each(function(){
if(this.href.indexOf('#') != -1)
{
var href=this.href.split('#')[1];
this.href = '#'+href;
}
});
I'm trying to iterate through a list of elements and wrap them in a link tag. However, my list displays differently than I want to.
Here is what it should look like: http://jsfiddle.net/eMexU/
HTML
<div id="list" data-role="listview">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</div>
Here is what it looks like when I use $.each and wrapInner(): http://jsfiddle.net/zpFDa/1/
HTML
<div id="list" data-role="listview">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</div>
JS
$("#list li").each(function () {
$(this).wrapInner('')
});
The only way to do this, is replacing existing li with new ones and then call .listview('refresh') to apply styles / enhance markup.
Demo
$("#list li").each(function () {
var text = $(this).text();
$(this).replaceWith('<li>' + text + '</li>')
});
$('#list').listview('refresh');
What is a cool way to apply this? I need a script that exchange two < li>'s position in an < ul>.
It think that should be possible to achieve. Thanks for your response.
HTML
<div id="awesome">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
</ul>
</div>
Pseudo Javascript (JQuery)
$("#awesome ul li:eq(1)").exchangePostionWith("#awesome ul li:eq(3)");
HTML Result
<div id="awesome">
<ul>
<li>Item 1</li>
<li>Item 4</li>
<li>Item 3</li>
<li>Item 2</li>
<li>Item 5</li>
</ul>
</div>
You can use jQuery's .after() for moving elements around. I cloned one of them so the original can remain as a placeholder. It's like if you wanted to switch variables a and b, you'd need a third temporary variable.
$.fn.exchangePositionWith = function(selector) {
var other = $(selector);
this.after(other.clone());
other.after(this).remove();
};
Now your pseudocode $("#awesome ul li:eq(1)").exchangePositionWith("#awesome ul li:eq(3)"); isn't so pseudo :-)
$("ul li a").click(function () {
$(this).parent().insertBefore('ul li:eq(0)');
});
<ul>
<li><a>a</a></li>
<li><a>b</a></li>
<li><a>c</a></li>
<li><a>d</a></li>
<li><a>e</a></li>
<li><a>f</a></li>
</ul>
Is it possible to clone a specific < li> and put it above an other specific < li>?
Any clue would help me..?
HTML
<div id="main">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</div>
Pseudo Javascript (JQuery)
$('#main ul li:eq(3)').duplicateAndPutAbove('#main ul li:eq(2)');
HTML Result
<div id="main">
<ul>
<li>Item 1</li>
<li>Item 3</li> <!-- Item 3 was duplicated (or cloned) and then putted ABOVE Item 2 -->
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</div>
You were really close, you wanted clone and insertBefore (and remember that eq is zero-based):
$('#main ul li:eq(2)').clone().insertBefore('#main ul li:eq(1)');
Live example
$('#main ul li:eq(3)').clone().insertBefore('#main ul li:eq(2)');
Demo: http://jsfiddle.net/karim79/8LpuN/
var elem = $('li').contains('3').clone(); // make a copy
$('li').contains('Item 3').before(elem); // insert before the cloned element
$('#main ul li:eq(3)').clone().insertBefore('#main ul li:eq(2)');
The code expands and collapses a list in which list items can have sublists. Any ideas to refactor this code - especially the toggling part. Is it necessary to use closures here ?
$(function()
{
$('li:has(ul)')
.click(function(event){
if (this == event.target)
{
var that = this;
$('li:has(ul)').children().filter(':not(:hidden)').parent().each(function(x){
if(this != that)
toggleList(this);
});
toggleList(this);
}
})
.css({cursor:'pointer', 'list-style-image':'url(plus.gif)'})
.children().hide();
$('li:not(:has(ul))').css({cursor: 'default', 'list-style-image':'none'});
});
function toggleList(L)
{
$(L).css('list-style-image', (!$(L).children().is(':hidden')) ? 'url(plus.gif)' : 'url(minus.gif)');
$(L).children().toggle('fast');
}
EDIT:
The script works on the following HTML snippet (source: jQuery in Action). Actually I was trying to extend the script given in the book.
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>
Item 3
<ul>
<li>Item 3.1</li>
<li>
Item 3.2
<ul>
<li>Item 3.2.1</li>
<li>Item 3.2.2</li>
<li>Item 3.2.3</li>
</ul>
</li>
<li>Item 3.3</li>
</ul>
</li>
<li>
Item 4
<ul>
<li>Item 4.1</li>
<li>
Item 4.2
<ul>
<li>Item 4.2.1</li>
<li>Item 4.2.2</li>
</ul>
</li>
</ul>
</li>
<li>Item 5</li>
</ul>
Your code doesn't work for me in Safari. When I click on a sub-list, the top-list is toggled.
How about:
$(document).ready(function() {
$('li:has(ul)').click(function(event) {
$(this).css('list-style-image', $(this).children().is(':hidden') ? 'url(minus.gif)' : 'url(plus.gif)')
$(this).children().toggle('fast')
return false
})
.css({cursor:'pointer', 'list-style-image':'url(plus.gif)'})
.children().hide()
$('li:not(:has(ul))').click(function(event) { return false })
.css({cursor:'default', 'list-style-image':'none'})
})
