在发送请求之前编辑href链接

Question

I have this code :

<a class="myLink" href='http://www.website.it/'>Link</a>

<script type="text/javascript">
    var stringToSend = "";
    $('.myLink').click(function() {
        stringToSend="?param=1";
    }); 
</script>

and, as you can see, I'd like to add stringToSend to the href (so the request will be at http://www.website.it/?param=1 ).

How can I do it?

Answer 1

Just modify the href with new href and you are done.

$('.myLink').click(function() {
    $(this).attr("href", this.href + "?param=1");
});

Answer 2

You should also prevent the default behavior like this:

var stringToSend = "";

// Use this to actually navigate to the changed Uri
$('.myLink').click(function(event) {
    event.preventDefault();
    stringToSend = "?param=1";
    window.location.href = $(this).attr('href') + stringToSend;
}); 

// Use this just to change the Href, without navigating to uri
$('.myLink').click(function(event) {
    event.preventDefault();
    stringToSend = "?param=1";
    var newUri = $(this).attr('href') + stringToSend;
    $(this).attr("href", newUri);
});

Answer 3

When clicking, you could stop the current URL, and navigate to another:

var stringToSend = "";
$('.myLink').click(function() {
    stringToSend="?param=1";
    window.location.href = $(this).attr('href') + stringToSend; // navigate to new URL
    return false; // abort navigation to URL from <a>
}); 

Answer 4

Just set the window.location on your click, and return false to prevent the default behaviour.

A such:

<a class="myLink" href='http://www.website.it/'>Link</a>

<script type="text/javascript">
    var stringToSend = "";
    $('.myLink').click(function() {
        window.location.href = this.href + "?param=" + stringToSend;
        return false;
    }); 
</script>
