jquery string to function convert

Question

is this possible?

I will change


var          


        

Answer 1

You would use eval() but what you are doing seems like a really bad idea:

var x = $('#id').attr('jq');
eval(x);

The reason this is bad, is you are not separating function from structure. HTML is meant to describe structure, not interactivity and function.

JavaScript is meant to provide that interaction and enhancement, but not structure. Using the jQuery inline like that is a violation of that separation. Just food for thought...

Answer 2

you can use new Function MDN

body:

<div id='MyFunc' func="alert('Hello!');" >On Load raise an Alert</div>

js:

var myFunc = myFunc || document.getElementById('MyFunc'),
        hello = new Function( myFunc.getAttribute('func'));
    hello.call(this);

give it a try:
