通过JavaScript调整html标签和CSS样式

Question

My program generates the following html code. And I need to adjust it via client side scripting (jquery) in order to look exactly the code I have found extreme below. Please note I can't modify the code server-side. I need to remove ul and li tags while retaining the href links and tag names and add a css class. I also need to remove the given font size: 10px. I am not very expert in js so I need your help figuring out how to do that. I have tried some scripts including the following but it entirely removes all the li tags and their contents.

<script type="text/javascript">
var lis = document.querySelectorAll('.Zend_Tag_Cloud li');
    for(var i=0; li=lis[i]; i++) {
        li.parentNode.removeChild(li);
}
</script> 

The original code generated by my program:

<ul class="Zend_Tag_Cloud">
        <li>
            <a href="/content/article/tag/136/" style="font-size: 10px;">workout  definition</a>
        </li>
        <li>
            <a href="/content/article/tag/140/" style="font-size: 20px;">workout  plans for men</a>
        </li>
        <li>
            <a href="/content/article/tag/139/" style="font-size: 20px;">workout  program</a>
        </li>
        <li>
            <a href="/content/article/tag/141/" style="font-size: 20px;">workout  routines for beginners</a>
        </li>
        <li>
            <a href="/content/article/tag/138/" style="font-size: 20px;">workout  schedule</a>
        </li>
        <li>
            <a href="/content/article/tag/137/" style="font-size: 20px;">workouts at home</a>
        </li>
    </ul>

The final html code should look like the following:

<a class="in-the-news-bar__link" href="/content/article/tag/136/">workout  definition</a>
<a class="in-the-news-bar__link" href="/content/article/tag/140/">workout  plans for men</a>
<a class="in-the-news-bar__link" href="/content/article/tag/139/">workout  program</a>
<a class="in-the-news-bar__link" href="/content/article/tag/141/">workout  routines for beginners</a>
<a class="in-the-news-bar__link" href="/content/article/tag/138/">workout  schedule</a>
<a class="in-the-news-bar__link" href="/content/article/tag/137/">workouts at home</a>

Answer 1

What about this?

    var $zendTagCloudLinks = $(".Zend_Tag_Cloud").find("a")
        .addClass("in-the-news-bar__link")
        .removeAttr("style");

    $zendTagCloudLinks.insertAfter(".Zend_Tag_Cloud");
    $(".Zend_Tag_Cloud").remove();

Answer 2

This code converts each li to a div with the class stuff. It uses jQuery. Additionally, it removes the ul entirely (I believe, per your request).

<div class="restyle">

<ul class="Zend_Tag_Cloud">
    <li>
        <a href="/content/article/tag/136/" style="font-size: 10px;">workout  definition</a>
    </li>
    <li>
        <a href="/content/article/tag/140/" style="font-size: 20px;">workout  plans for men</a>
    </li>
    <li>
        <a href="/content/article/tag/139/" style="font-size: 20px;">workout  program</a>
    </li>
    <li>
        <a href="/content/article/tag/141/" style="font-size: 20px;">workout  routines for beginners</a>
    </li>
    <li>
        <a href="/content/article/tag/138/" style="font-size: 20px;">workout  schedule</a>
    </li>
    <li>
        <a href="/content/article/tag/137/" style="font-size: 20px;">workouts at home</a>
    </li>
</ul>

</div>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
newHtml = "";
$("div.restyle ul.Zend_Tag_Cloud li").each(function() {
    $(this).find("a").attr("style","").addClass("in-the-news-bar__link");
    newHtml += "<div class='stuff'>" + $(this).html() + "</div>";
});
$(".restyle").html(newHtml);
</script>

You can iterate over the list links - add the class and remove the style attribute and then prepend it to the parent div that contains the list (I called that #parentDiv) - note that removing the lis t structure will cause all the a's to display in a sequence on one line rather than on separate lines - so I also added a CSS rule to cause them to display:block.

 $(document).ready(function(){ $('.Zend_Tag_Cloud li a').each(function(){ $(this).addClass('in-the-news-bar__link').removeAttr('style'); $('#parentDiv').prepend($(this).parent().html()); }) $('.Zend_Tag_Cloud').remove(); }) 

 a{display:block} 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="parentDiv"> <ul class="Zend_Tag_Cloud"> <li> <a href="/content/article/tag/136/" style="font-size: 10px;">workout definition</a> </li> <li> <a href="/content/article/tag/140/" style="font-size: 20px;">workout plans for men</a> </li> <li> <a href="/content/article/tag/139/" style="font-size: 20px;">workout program</a> </li> <li> <a href="/content/article/tag/141/" style="font-size: 20px;">workout routines for beginners</a> </li> <li> <a href="/content/article/tag/138/" style="font-size: 20px;">workout schedule</a> </li> <li> <a href="/content/article/tag/137/" style="font-size: 20px;">workouts at home</a> </li> </ul> </div>

You could use something like the following. This solution is a bit more verbose, but doesn't require jQuery. Essentially, you put your list in a parent element (.Zend_Tag_Cloud--container) and the javascript finds the links and inserts them back into the container (removing original style and adding a class) overwriting the original ul. Depending on the context you are using this in, you will want to considering how to best namespace your class / ID names.

 var links = []; var container = document.querySelector('.Zend_Tag_Cloud--container'); var lis = document.querySelectorAll('.Zend_Tag_Cloud a'); for (var i=0; li=lis[i]; i++) { links.push(li); } container.innerHTML = ''; links.forEach(function(link) { link.style = null; link.className += " in-the-news-bar__link"; container.appendChild(link); }); 

 <div class="Zend_Tag_Cloud--container"> <ul class="Zend_Tag_Cloud"> <li> <a href="/content/article/tag/136/" style="font-size: 10px;">workout definition</a> </li> <li> <a href="/content/article/tag/140/" style="font-size: 20px;">workout plans for men</a> </li> <li> <a href="/content/article/tag/139/" style="font-size: 20px;">workout program</a> </li> <li> <a href="/content/article/tag/141/" style="font-size: 20px;">workout routines for beginners</a> </li> <li> <a href="/content/article/tag/138/" style="font-size: 20px;">workout schedule</a> </li> <li> <a href="/content/article/tag/137/" style="font-size: 20px;">workouts at home</a> </li> </ul> </div>

So we get a reference to the ul that we'll eventually replace with a document fragment. This document fragment contains the a we find within the ul . We will replace the ul with the fragment using jQuery's replaceWith() .

The document fragment acts as a container to hold the a we find until we're ready to insert the new markup. Document fragments are fast and appending our items to one allow us to perform a single DOM insertion for all of the found a .

end() allows us to "rewind" to the previous collection as once we performed find() we were working with a collection of a and not the original collection contained in $ul .

 $( function () { var $ul = $( 'ul' ), frag = document.createDocumentFragment(); $ul.find( 'a' ) .each( function ( i, item ) { frag.appendChild( $( item ).addClass( 'in-the-news-bar__link' ).attr( 'style', null )[ 0 ] ); } ) .end() .replaceWith( frag ); } ); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <ul class="Zend_Tag_Cloud"> <li> <a href="/content/article/tag/136/" style="font-size: 10px;">workout definition</a> </li> <li> <a href="/content/article/tag/140/" style="font-size: 20px;">workout plans for men</a> </li> <li> <a href="/content/article/tag/139/" style="font-size: 20px;">workout program</a> </li> <li> <a href="/content/article/tag/141/" style="font-size: 20px;">workout routines for beginners</a> </li> <li> <a href="/content/article/tag/138/" style="font-size: 20px;">workout schedule</a> </li> <li> <a href="/content/article/tag/137/" style="font-size: 20px;">workouts at home</a> </li> </ul> 

Answer 6

You can use $.each() to loop through the a tags, add the class, remove the style attribute, and append it to the document before the .Zend_Tag_Cloud list, then remove the list using $.remove()

 $('a').each(function() { $(this).addClass('in-the-news-bar__link').removeAttr('style').insertBefore('.Zend_Tag_Cloud'); }); $('.Zend_Tag_Cloud').remove(); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <ul class="Zend_Tag_Cloud"> <li> <a href="/content/article/tag/136/" style="font-size: 10px;">workout definition</a> </li> <li> <a href="/content/article/tag/140/" style="font-size: 20px;">workout plans for men</a> </li> <li> <a href="/content/article/tag/139/" style="font-size: 20px;">workout program</a> </li> <li> <a href="/content/article/tag/141/" style="font-size: 20px;">workout routines for beginners</a> </li> <li> <a href="/content/article/tag/138/" style="font-size: 20px;">workout schedule</a> </li> <li> <a href="/content/article/tag/137/" style="font-size: 20px;">workouts at home</a> </li> </ul>
