将变量添加到href URL的末尾onClick JQUERY

Question

I feel like this should work, but doesn't. Not sure what I'm doing wrong.

function addURL()
{   
$(this).attr('href', function() {
return this.href + '&cylnders=12';
}   


<a onclick="addURL();" href="/search-results/?var1=red&var2=leather">Click this</a>

Answer 1

First, you are missing a bunch of brackets:

function addURL()
{
    $(this).attr('href', function() {
        return this.href + '&cylnders=12';
    });
}

Second, in your code "this" refers to the window, not the element. Try this instead:

<a onclick="addURL(this)" href="/search-results/?var1=red&var2=leather">Click this</a>

function addURL(element)
{
    $(element).attr('href', function() {
        return this.href + '&cylnders=12';
    });
}

Answer 2

Why don't you add an ID or Class to your link href to identify it through jquery? It seems like your link is triggered before you can add any data to href attribute.

<a class="datalink" href="/search-results/?var1=red&var2=leather">Click this</a>
<script>

$('.datalink').attr('href', function() {
return this.href + '&cylnders=12';

});

</script>

Answer 3

     function addURL()
      {
     var data=window.location+"&cylnders=12";
     alert(data);
     }

Try this concept. hope it will give you some solution.

Try this too

          function addURL()
          {
               window.location.href='/search-results/?var1=red&var2=leather&cylnders=12'
           }
