I want to set the src of an image to the return value of a function call. Here is what I am doing now:
<img src="get_src()" alt="can't display picture" />
and the script is:
function get_picA() {
return "picA.png";
}
But it doesn't work.
You can't set it like that.
You can change the value with javascript:
<img id="image" src="picB.png" alt="can't display picture" />
document.getElementById("image").setAttribute("src","picA.png");
You can't do it that way. The src attribute doesn't interpret javascript.
You may do it like this:
<img id="picA">
<script type="text/javascript">
function get_picAPath(){
return "picA.png";
}
document.onload = function(){
document.getElementById('picA').src= get_picAPath();
};
</script>
