Hey guys, I am just wondering if it is possible to call a javascript function inside a JQuery plugin? I want to call a function inside my jquery file if a certain condition is met.

JavaScript

var displayMessage = function (objNotification) {

              this.hello = function () {
                   alert('Condition met!');
               }

               var json = JSON.parse(objNotification);
//this is where I call my plugin where I pass a JSON object. I want to call the function hello in here?
               notification(json);
           };

Thanks in advance guys.

Yes, this is possible and not even a problem. The function to be called should be created as a function object before (in time order, not in the order of the code text) calling, that's all. This is scripting, very relaxed in this respect.

Just call it; what are you waiting for, my approval? :-)

What is the error ?
Do you see any error in console tab of FireBug in FireFox ?

Sergey Alexandrovich Kryukov 21-May-13 14:10pm

In the code you've shown, you never call this function. We cannot help you with your code if you not showing the exact code which cases the problem.

He yes just says hello is underfined or not an object

Sergey Alexandrovich Kryukov 21-May-13 14:08pm

Define it. Make an object (assign). Run under the debugger to see in what line, run again and examine the offending object. Take care about it.

Ok define, ver hello = function () {
alert('Condition met!');
}

in my plugin I call

this.hello();
error: Object doesnt support method or property 'hello'

Sorry its been a really long day:), I know im probably just calling it wrong in the plugin?

Sergey Alexandrovich Kryukov 21-May-13 14:27pm

Please see:


hello = function() {
    alert("...");
}

hello(); // not this.hello();

You could do this.hello() (someObject().hello()) if you made it a member of some object:

someObject = "anything to initialize it";
someObject.hello = function() { // yes, you can add any member to any object
    alert("...");
};

// ...

someObject.hello(); // the call of the member function
