Im writing my own plugin, and want to be able to run some user-code.

So to simply things, Ive just written a simple POC:-
function tcDialog() {
    var onCloseFunction = function () { alert('hi'); };

    function onClose($tmpFunction) {
        onCloseFunction = $tmpFunction;
    }
    
    function runMe() {
        onCloseFunction();
    }
}

$(document).ready(function () {
    var viewJob = new tcDialog();
    viewJob.onClose(function () { alert ('hi2'); });
    viewJob.runMe();
});

Open in new window

I have been looking at using the eval function, but have lots of forums saying dont use it, but cant see an alternative.

Anyone available to point me in the right direction of fixing my code to run the function as a variable?

Thank you in advance.

function tcDialog() {
    this.onCloseFunction = function () { alert('hi'); },
    this.onClose=function(tmpFunction) {
    this.onCloseFunction = tmpFunction;
    },
    this.runMe=function() {
        this.onCloseFunction();
    }
}

$(function () {
    var viewJob = new tcDialog();
    viewJob.onClose(function () { alert ('hi2'); });
    viewJob.runMe();
});

Open in new window

you shouldn't use eval.  What Randy has provided will work for you.
