how to execute ajax output script

Question

I\'m getting an ajax output success data.

Where the data contains some html text and a script.

But the script is not executing, how can I execute the script.

Assuming you are not using JSON or jQuery, or any other library, and your AJAX call returns some HTML and/or javascript which is being added to your existing document (eg. using innerHTML), any javascript returned using AJAX will not execute in the browser - except for events on elements in the HTML.

So if your AJAX call returns , the js alert will work ok, but if your AJAX call returns it will not execute. In that case, you would have to parse the result to extract the javascript and execute it, using a function such as this:

function extract_and_execute_js(output_to_parse)
{    
    if(output_to_parse != '')    
    {    
        var script = "";
        output_to_parse = output_to_parse.replace(/]*>([\s\S]*?)<\/script>/gi, function(){if (output_to_parse !== null) script += arguments[1] + '\n';return '';});
        if(script) 
        {
            if (window.execScript)
            {
                window.execScript(script);
            }
            else
            {
                window.setTimeout(script, 0);
            }
        }
    }
}
