How to pass data to a jQuery dialog button

Question

I created a php/javaScript automatisation of our form creation. Thus, when a dialog is created the button are added dynamicly and correctly, but I cannot access the JSON object in the function trigged on the click of the button.

Here is a exemple (The alert does not work, is not display):

aButtons[oGeneratedFormButtons[x].label] = function(){ alert(oGeneratedFormButtons[i].label); });

Can I pass data to the function or is there a way to know which button has been clicked.

Here is a simple sample : http://jsfiddle.net/DavidLaberge/h4Cgp/13/

try using closure like this:

for (var x = 0; x < JSON.length; x++) {
    aButtons[JSON[x].label] = (function() {
        var i = x;
        return function() {
            alert(i);
            alert(JSON[i].label);
        }
    })();
}

Here is fiddle.

@David, my example is using closure feature of javascript. You can find needed info [here](http://stackoverflow.com/questions/111102/how-do-javascript-closures-work/111200#111200) – Molecular Man Jul 22 '11 at 12:44

Are you sure that the problem is not that you are using a different variable (i instead of x) inside the function? Because oGeneratedFormButtons[x].label should be accessible inside the function if it's accessible outside it.

aButtons[oGeneratedFormButtons[x].label] = function(){ alert(oGeneratedFormButtons[x].label); });

Sorry for the typo, I forgot to change it after testing different ways that I could think about. – David Laberge Jul 22 '11 at 11:28
@David the alerto doesn't work means that it alerts undefined or that there is no alert?You should also post the rest of your code. – Nicola Peluchetti Jul 22 '11 at 11:32
