Changing the href Attribute of an Anchor Tag Using JavaScript on Button Click

In web development, the need to dynamically modify the href attribute of an anchor ...jhhghj

Alternatively, you can prevent the page from scrolling using:

...jhhghj

or return false from the f1() function:

function f1() {
    document.getElementById("abc").href = "xyz.php";          
    return false;
}

...jhhghj

For a more unobtrusive approach, employ an external JavaScript file:

...jhg
...jhhghj

document.getElementById("myLink").onclick = function() {
    document.getElementById("abc").href = "xyz.php";
    return false;
};
