jQuery ajax调用未呈现html

Question

I am making an ajax call to the database server to get the image as a base64 encoded string, the server is returning the base64 encoded image correctly I did check this in firebug, I need to use this encoded string as an hyper reference of an anchor on a page.

here is my client code

$.ajax({
        url: '../Handlers/ImageHandler.ashx',
        data: { ID: imageId },
        type: 'GET',
        dataType: 'text/plain',
        success: onAjaxSuccess,
        error: onAjaxFail
    });

function onAjaxSuccess(result) {
    var anchor = document.getElementById('hlImage0');

    var base64Image = 'data:image/png;base64,' + result;
    anchor.href = base64Image;
}

The problem here is the anchor element hlImage0 is not setting the href property and nothing is rendered on the page from the onAjaxSuccess callback.

Answer 1

Image balise have on href attribute !

Try changing anchor.href by anchor.src instead !
