JQuery :: Select A Tags With No Ul > Li >a Children?
Oct 7, 2010
I have about 13 ul li a items in a list and some have nested lists within them e.g. ul li ul li a and some don't. I want to prevent the default action on only a elements that have nested lists within them but not prevent default action for ones that don't. Here's an example of the markup.
[Code]...
However, instead, is there a way to tell jQuery to only apply this preventDefault to ul li a elements that have ul li a descendants/children (not sure of correct terminology here) so I can have the list items in any order?
I need to select the last children of parent elements
For example
<ul> <li></li> <-This will have the background #1a <li></li> <-This will have the background #1a <li><ul>
[Code]....
So I would need the last children. If there is no nested element then that is considered the last child. I have to write a jquery script to apply a background to the last children. A nested element can have a nested element and then that element's children will be considered the last ones so they will get the background but not the parents of those children. If the item has no children then that item will have a background.
So there are 3 different backgrounds. Each letter a, b c will represent a lighter tone compared to the previous color. C is lighter than B, B is lighter than A etc. So this will have to be a "smart" system in which the ul li will be updated and depending if it is the last one inhierarchyit will not have the arrow.
I have my website getting a value as a result of an ajax call. After that, I would like to insert that result (a string) into a tag. However, I would like to insert that result in a way that (1) it must have opacity = 0, then (2) it will slideDown() so the whole content list being pushed down using animation, and finally (3) change opacity = 1. Imagine this is just like a Facebook message list insert process The way I am planning to do this is to return the result string from ajax to opacity=0 first. However, I don't know how to use jQuery to select a tag from within a string. I know jQuery only select from the DOM. So how to do this?
I have some auto-generated code in a similar format to this:
<li class="item"> <a class="link1" href="#">Post Title</a> Text I want to remove <div class="content">
[Code].....
I want to select the line of text ("Text I want to remove" - with no HTML tags around it) and hide it using CSS (or remove it all together, if I can). I have tried using insertAfter to put a start <span> tag at the start of the line, and insertBefore to close the </span> tag at the end of the line (so I can apply CSS display:none; to it), but clearly JQuery doesn't work like that.
Is there another way to get rid of this line of text?
I need to remove the checkbox and label when a checkbox is selected. For example: I check the checkbox "flashlight". --> The checkbox and the text "flashlight" slowly fade away
I'm trying to select a line a text and format it, only problem is there are no tags around it other than a closing </p> tag and a <br /> tag after it. Please see below the line in bold text which I'm trying to surround with <h3></h3> tags. [code]...
I have several pages, all with multiple select boxes. Each select has a different name, but contains the same values (ok, not ok, fixed, needs fixing). I am trying to write a single script that will loop through each select box on the page, find all the 'not ok' values, then send the select box name, with the option value to a holding area (probably an array) which will be emailed to someone once all the pages have been entered by the user.
At this time, I am just trying to figure out the looping through one page of select boxes. The script is currently tied to an onclick event for the submit button.
I'm currently working with a bit of javascript to dynamically add <option>s into a select box. My code currently works fine in Internet Explorer, however in Firefox the dropdown only displays the first option in the list, and when clicked the other values aren't displayed.
Here is the code;
//ar_options is an array with the option to be displayed in.
for (count=0; count<number_of_options+1; count++) { document.forms['enquiry'].enquirytype.options[count] = new Option(ar_options[count],ar_options[count]); };
As I said - fine in Internet Explorer, but not in Firefox. I did discover some discussions about this, which were talking about an issue and workarounds but I couldn't get any of them to work. I have also tried simply using the document.write() function to output the HTML in the correct place. However this is just hte same, works in IE but not Firefox.
Can't seem to make it work, I have seen many examples but they are all just for 1 div tag. When i trymore than one it doesn't work anymore.The first one works, if i have more than 1 then the other don't work.
using the following jquery $(document).ready(function(){ $("#toggle-text").click(function () { var divvalue= this.value;
I've seen a variety of implementations around that enable selecting all or no checkboxes by using a checkbox to toggle that choice. However, I'm trying to find a way like this: I have two text links on my page: Select All, and Select None. How can I get those links to call a jquery function to select all or select no checkboxes in my form? As a little food for thought:
<head> $(function() { //function for selecting all or none...is there a way to make a single function that passes in a parameter to differentiate between selecting all or selecting none, or do I need a separate function for both?[code]....
I have a div containing many children all very different, each one as a different width. I need to get the width of all the children. I mean child1.width() + child2.width() + child3.width() etc... Of course as a new child can be added anytime I can not use the kind of things I put above.
I tried that among other things : $("div.mydiv").children().width(); But I only get the width ofthe first child.
just wondering if there is any way for the :contains to not look in children to find something? Tried $(':contains("$")');, but it returns everything. Was thinking of something like $(":not(':parent')").filter(':contains("$")');, but the console returns null (and even then it would exclude elements that have children and their text includes "$".)
Trying to make a script that looks through a page and finds the price on any page. The only way I could think of doing this relatively accurately is to search for all elements with "$" in the text, then get the one that has the largest height/width (That's problem #2, I think -- will deal with it once i get there :)
I'm trying to get an unordered list and its children as an HTML string on a mouseout event, but html()only selects the child elements:var theHtml = $('ul', this).html();I've tried using andSelf(), but that doesn't return the result I want:var theHtml =$('ul',this).and Self(). html();I can't choose $(this).html() as I need only the list.
Given the following markup <div id="menu"> <ul> <li><a id="home" href="#">Home</a></li> <li> <a id="about" href="#">About</a> <div>
About sub menu </div></li><li> <a id="products" href="#">Products</a> <div><h2>Books</h2> <ul><li>ColdFusion</li> <li>jQuery</li> <li>CSS</li> <li>HTML</li> <li>Groovy</li> <li>Hibernate</li> .....
How can I grab only the 1st level children of my node? I want direct decendents of menu only. My code below is grabbing all <li> which is going to be a problem. (function($){ $.fn.extend({ myplugin: function(options){ return this.each(function(){ // the object we are working with var obj = $(this); // get a list of menu items var menuItems = $('li',obj); }); }}); })(jQuery);
Taking the following markup <div id="menu"> <ul> <li><a id="home" href="#">Home</a></li> <li> <a id="about" href="#">About</a> <div>
About sub menu </div> </li> <li> <a id="products" href="#">Products</a> <div> <h2>Books</h2> .....
How can I grab the immediate li children only and not all of the li that fall in this object. The following gives me every single <li> which is not what I am looking for. (function($){ $.fn.extend({ myplugin: function(options){ return this.each(function(){ // the object we are working with var obj = $(this); // get a list of menu items var menuItems = $('li',obj); }); }}); })(jQuery);
It basically works, but only if I remove the code part where I first hide the children of the sidenav, but doesn't work when I want at default all children of the sidenav to be hidden and showed only if clicked a particular parent menu. 1. How can this be accomplished? 2. Also how can I hide the children of previous clicked parents when I click on another parent to chow it's children?
I am trying to assign a variable to a jquery object that is found using the children() and eq() methods. This is a simplified version of the html structure.[code]Here is the jquery code. All I want to do is assign an object to the variable and be able to manipulate the object through the variable. [code]Again this is a simplified version of my code but the structure is similar.
I have the following html and I'm trying to figure out how to delete the last rows the are children of div feed. I only want to leave a max of the first x rows. First I count them using $numdivs = $("#feed > div").size() - 1;. Then, I'm a bit lost on what to do next and have looked at the docs for children and thought of trying to traverse but can't seem to get it to work.
<body> <div id="search"> </div> <div id="feed"> <h2>Feed</h2> <div id="firstrow" class="row"/> <div id="1741946459" class="row">Test data for the first row</div> <div id="1741946327" class="row">Test data for the second row</div> <div id="1741939928" class="row">Test data for the blah row</div> <div id="1741939928" class="row">Test data for the blah2 row</div> <div id="1741939928" class="row">Test data for the blah3 row</div> </div> </body>
