Question

i am trying to put context path for an image in HTML.<img src="/MyWeb/images/pageSetup.gif">

Here /MyWeb is the ContextPath which is hardcoded. How can i get dynamically.

i am using as <img src=contextPath+"/images/pageSetup.gif">but image is not displaying. Is there any option.

You can’t write JavaScript in the src attribute. To do what you want, try some code like this:

var img = new Image();
img.src = contextPath + "/images/pageSetup.gif";
document.getElementById('display').appendChild(img);

Here the target; the place where you want to display the image, is a div or span, with the id display.

Demo

With HTML, you’ll have to take some extra traffic of producing an error, so you can replace the image, or you can send some traffic Google’s way. Please do not use this:

<img src='notAnImage' onerror='this.src= contextPath + "/images/pageSetup.gif" '>

Demo

Do not use this.
