Ok, Im wondering if it is possible to transfer the reference of the object to the functions. If you dont understand what im trying to say, this might help:

Ok, Im wondering if it is possible to transfer the reference of the object to the functions. If you dont understand what im trying to say, this might help:

//so i declare the variable `Editor`
var Editor = new (function(e, d){
    this.edit = e;
    this.dyna = d;
    this.old = ""; //and set these variables inside the object

    this.update = function() {
        var ta = $(Editor.edit)[0].value, dy = $(Editor.dyna)[0].contentDocument;
        //what i want is to be able to refer to the variables (ie. "edit") without using "Editor."
        if (Edito开发者_如何学JAVAr.old !== ta) {
            $(dy).text(ta);
            Editor.old = ta;
        }
        window.setTimeout(Editor.update, 150);
    }

    return this;
})("editor","dynamic");

So for the update function, I want to be able to do something like:

this.update = function() {
    var ta = $(edit)[0].value, dy = $(dyna)[0].contentDocument;
    if (old !== ta) {
        $(dy).text(ta);
        old = ta;
    }
    window.setTimeout(update, 150);
}

And it gives me the variables(edit, dyna, old) from the Editor object. Thanks.


Why aren't you just using the this prefix. So this.edit[0].value?

Maybe I am missing something as it's late here...


this inside your function refers to the object of the anonymous base function you have created.

Use this.propertyName to access its properties.

var ta = $(this.edit)[0].value, dy = $(this.dyna)[0].contentDocument;
