Html function clear jquery code example

In a previous question, I asked how to remove useless SPANs from a string and the result was to use: This works great BUT in the above example, it doesn’t take into account the color. Solution 4: This function should do it: Basically just looping through all the spans (you can always be more specific with locking down the section of spans you want to loop through) and setting the font and color with the latest found value.

Clean up HTML with jQuery?

Using jQuery, how can I turn this:

Note the useless spans are removed BUT the color is maintained.

In a previous question, I asked how to remove useless SPANs from a string and the result was to use:

This works great BUT in the above example, it doesn’t take into account the color.

Can anyone think of an effective to handle this?

In case that you want to preserve the inherited color property, one option is using css method, for preventing conflicts/better performance, you can filter the elements that has no descendant span elements.

$('span').css('color', function() < return $(this).css('color'); >).unwrap(); 

For filtering span s that have no descendant span elements you can use .filter() method. (I haven’t tested the performance of it versus the previous snippet):

$('span').filter(function() < return !$(this).find('span').length; >).css('color', function() < return $(this).css('color'); >).end() .unwrap(); 

If you could list all the properties you want this way can work.

If you have a common container you can do:

var $container = $('.container-for-useless-spans'); // This is an array of the properties to grab. var properties_to_get = ['color', 'font-size']; // Grab the CSS properties from the deepest span since it'll have all the parents styling. var styles_to_copy = $container.find('span:last').css(properties_to_get); // Just grab the text from the container and apply the styles that were on the deepest span.. $container.html($container.text()).css(styles_to_copy); 
  Something   
 

Here is a quick demo: http://jsbin.com/IneXasOL/1/edit?html,js,output

I personally would just clean up the HTML, though. This is silly, especially considering how trivial it is for the browser to handle it as it is.

I’m going to try and implement a multi-purpose, pure-JS solution. This will apply to all elements that have no siblings (ie. wrappers of wrappers), however note that in some cases this WILL break your site’s layout. I will go into detail on this after the code. Also note that I do NOT encourage use of this code. This is more an exercise of my ability to do something.

(function() < var all = document.getElementsByTagName("*"), l = all.length, i, k; for( i=l-1; i>=0; i--) < // by going backwards, children are processed before parents if( !all[i].parentNode || all[i].parentNode.children.length != 1) continue; // element is only child, apply its styles to parent node and transfer children for( k in all[i].style) < if( all[i].style.hasOwnProperty(k) && all[i].style[k] && typeof all[i].style[k] == "string") < all[i].parentNode.style[k] = all[i].style[k]; >> while(all[i].firstChild) all[i].parentNode.appendChild(all[i].firstChild); // finally, remove current node all[i].parentNode.removeChild(all[i]); > >)(); 

All being well, this should produce the desired effect on the entire document.

I REPEAT: THIS IS BAD! You should be producing tidy HTML, and shouldn’t even be using the inline style attribute anyway. Separate content and format, or something like that, I dunno. I use the style attribute and I don’t care.

Anyways, this WILL break pages in some circumstances. For example, assume you have a list with a single item:

The code above will change it to:

Which is, for obvious reasons, invalid. This could maybe be fixed with an additional check, like so:

if( !all[i].pare . || all[i].nodeName != all[i].parentNode.nodeName) continue; 

ONE MORE TIME : This is NOT code you should be using for anything other than as an exercise!

This function should do it:

var font, color; $(span).each(function () < if ($(this).css('font-size')) < font = $(this).css('font-size');>if ($(this).css('color')) < font = $(this).css('color');>>); $(span).unwrap().addCss(); 

Basically just looping through all the spans (you can always be more specific with locking down the section of spans you want to loop through) and setting the font and color with the latest found value. At the end you unwrap all the spans and set the font-size and color to the values that would have last been encountered.

Writing clear jquery code

I have a html page with multiple buttons which all execute a jquery ajax code. At the moment I have created a click event handler for every button, but is there any cleaner method?

$(function() < $("#btn_id_1").click(function() < $.ajax(< url: 'url1', type: 'POST', . >> $("#btn_id_2").click(function() < $.ajax(< url: 'url2', type: 'POST', . >> $("#btn_id_3").click(function() < $.ajax(< url: 'url2', type: 'POST', . >> > 

Use data attributes and unobstrucive javascript:

My button My button My button My button 

As url for each button are different, then put data attribute for each button like below

 You can use comma seperator selector like below :

$("#btn_id_1, #btn_id_2, #btn_id_3").click(function() < $.ajax(< url: $(this).data('url'), type: 'POST', . >> 

Use attribute-selector is suitable for the context

$("button").click(function (event) < var href = event.srcElement.getAttribute("href"); $.ajax(< url: href, . >); >); 

Jquery clear() Code Example, // Remove all child nodes of the set of matched elements from the DOM // This method does not accept any arguments. $(«div.parent»).empty();

JQuery Masonry remove function example

I have implemented jQuery masonry to our site and it works great. Our site is dynamic and users must be able to add/remove masonry box’s. The site has an add example but no remove example. Our db is queried returning x number of items. Looping through they are loaded and displayed. Here’s a code sample: (we are use F3 framework and the F3:repeat is it’s looping mechanism.).

In the javascript code the item id number is unique and is passed into the function. It’s also the div id# to distinguish each box. I’ve tried various combinations and methods but can’t seem to get this to work.

Has anyone out there successfully removed an item and how did you do it? Thx.

Currently you appear to be passing a string full of html to the masonry remove method. Pass it the actual jQuery wrapped element by not including .html()

.empty()

Description: Remove all child nodes of the set of matched elements from the DOM.

version added: 1.0 .empty()

This method removes not only child (and other descendant) elements, but also any text within the set of matched elements. This is because, according to the DOM specification, any string of text within an element is considered a child node of that element. Consider the following HTML:

div class="container">
 div class="hello">Hello div>
 div class="goodbye">Goodbye div>
 div>

We can target any element for removal:

This will result in a DOM structure with the Hello text deleted:

div class="container">
 div class="hello"> div>
 div class="goodbye">Goodbye div>
 div>

If we had any number of nested elements inside , they would be removed, too.

To avoid memory leaks, jQuery removes other constructs such as data and event handlers from the child elements before removing the elements themselves.

If you want to remove elements without destroying their data or event handlers (so they can be re-added later), use .detach() instead.

Example:

Removes all child nodes (including text nodes) from all paragraphs
