How to Change the Href Attribute For a Hyperlink Using Jquery

How to change the href attribute for a hyperlink using jQuery

Using

$("a").attr("href", "http://www.google.com/")

will modify the href of all hyperlinks to point to Google. You probably want a somewhat more refined selector though. For instance, if you have a mix of link source (hyperlink) and link target (a.k.a. "anchor") anchor tags:

<a name="MyLinks"></a>
<a href="http://www.codeproject.com/">The CodeProject</a>

...Then you probably don't want to accidentally add href attributes to them. For safety then, we can specify that our selector will only match <a> tags with an existing href attribute:

$("a[href]") //...

Of course, you'll probably have something more interesting in mind. If you want to match an anchor with a specific existing href, you might use something like this:

$("a[href='http://www.google.com/']").attr('href', 'http://www.live.com/')

This will find links where the href exactly matches the string http://www.google.com/. A more involved task might be matching, then updating only part of the href:

$("a[href^='http://stackoverflow.com']")
   .each(function()
   { 
      this.href = this.href.replace(/^http:\/\/beta\.stackoverflow\.com/, 
         "http://stackoverflow.com");
   });

The first part selects only links where the href starts with http://stackoverflow.com. Then, a function is defined that uses a simple regular expression to replace this part of the URL with a new one. Note the flexibility this gives you - any sort of modification to the link could be done here.

Change the href for a hyperlink by using its value jQuery

$("a").filter(function(){
return $(this).text() == 'Accept';}).attr('href', 'http://www.accept.com');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><a href="Accept.php">Accept</a>

Change link href via jQuery

$("#quicktabs-tab-galeri-1").attr("href", new_href);

That should do the trick for you.

Problems with the code fragment

First off, it is not a full document but a code fragment, as such it doesn't include appropiate headers. We can disregard this understanding that the provided code belongs to a larger document.

The following problems are present in such code fragment:

The img tags require a non-empty src attribute and a alt attribute.
The a tags require a valid url value in their href attribute.
There doens't seem to be a closing tag for <a href="http://">
And finally thig thing that doesn't make sense <li<a href="http://google.com/home/inner_links">

Now, this is beyond the question, but given that you have the following fragment:

<div class="main-menu">
    <ul><li<a href="http://google.com/home/inner_links"></a></li></ul>
</div>

We can see that you have closing li and ul tags. So I would expect that you were trying to do as follows:

<div class="main-menu">
    <ul><li><a href="http://google.com/home/inner_links"></a></li></ul>
</div>

Solution

The code I'm suggesting to use to edit the href values is the following:

$('.branding').find('img').parent().attr('href', 'newhref');

That is selecting the parents of all the img that are inside elements with class "branding", and setting the href attribute of them.

Demo with original code fragment

$('.branding').find('img').parent().attr('href', 'newhref');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="branding">
  <a href="http://google.com">
<img class=" preload-me"/>
  </a>
  <a href="http://google.com">
<img class=" preload-me"/>
  </a>
  <a href="http://">
<div class="main-menu">
<ul><li<a href="http://google.com/home/inner_links"></a></li></ul>
</div>
</div>
