How to change href of <a> tag on button click through javascript

Without having a href, the click will reload the current page, so you need something like this:

<a href="#" onclick="f1()">jhhghj</a>

Or prevent the scroll like this:

<a href="#" onclick="f1(); return false;">jhhghj</a>

Or return false in your f1 function and:

<a href="#" onclick="return f1();">jhhghj</a>

....or, the unobtrusive way:

<a href="#" id="abc">jhg</a>
<a href="#" id="myLink">jhhghj</a>

<script type="text/javascript">
  document.getElementById("myLink").onclick = function() {
    document.getElementById("abc").href="xyz.php"; 
    return false;
  };
</script>

Exactly what Nick Carver did there but I think it would be best if used the DOM setAttribute method.

<script type="text/javascript">
    document.getElementById("myLink").onclick = function() {
        var link = document.getElementById("abc");
        link.setAttribute("href", "xyz.php");
        return false;
    }
</script>

It's one extra line of code but find it better structure-wise.


remove href attribute:

<a id="" onclick="f1()">jhhghj</a>

if link styles are important then:

<a href="javascript:void(f1())">jhhghj</a>

Here's my take on it. I needed to create a URL by collecting the value from a text box , when the user presses a Submit button.

<html>
<body>

Hi everyone

<p id="result"></p>

<textarea cols="40" id="SearchText" rows="2"></textarea>

<button onclick="myFunction()" type="button">Submit!</button>

<script>
function myFunction() {
    var result = document.getElementById("SearchText").value;
	document.getElementById("result").innerHTML = result;
	document.getElementById("abc").href="http://arindam31.pythonanywhere.com/hello/" + result;
}		
</script>


<a href="#" id="abc">abc</a>

</body>
<html>
