I have a link, which I want to make a DELETE request with JQuery with AJAX.

if(confirm("Are you sure?")) {
   $.ajax({
    url: $(this).attr("href"),
    type: 'DELETE',
    success: function(result) {
            // Do something with the result
        }
    });
}

result is a wad of Javascript I would like to run. How do I get it to run my returned script?

• javascript
• jquery
• ajax

• 2 Please don't do that. Don't return Javascript code, don't eval, just return some kind of identifier and let your Javascript decide what to do. – kapa Commented Jun 10, 2011 at 16:10
• @bazmegakapa Are you saying this for a separation of concerns purpose or is there a technical reason why this is a bad idea? – Drew Commented Jun 10, 2011 at 16:12
• eval should be avoided whenever possible. I don't think there is a real reason for returning a piece of code. You could return some kind of JSON, and define in your Javascript what should happen to it. – kapa Commented Jun 10, 2011 at 16:14

success: function(result) {
    eval(result);
}

Use the dataType: 'script' option

$.ajax({
    url: $(this).attr("href"),
    type: 'DELETE',
    dataType: 'script'
});

Or simply,

$.getScript($(this).attr("href")); // Won't use 'DELETE' http type

Check the javascript Eval method. It allows you to execute js code which is represented as a string.
