Any of those help First of all, the function is called Anonymous self executing function.
Secondly, it is better to define your function the following way as the very well known library jQuery does:
(function(window) {
    // Define your function here
    var Cms = function () {
         // Function body
    };

    // Add the function to the window scope so that it can be accessed anywhere
   window.Cms = Cms;
})(window);
var Cms = function () {
    this.test = function () {
        console.log("Hello");
    };

    this.testAgain = function() {
        console.log("Hello again");
    };
};
// First create an object of Cms
var md = new Cms();

// Then call the methods
md.test(); // Hello
md.testAgain(); // Hello again
var Cms = function () {
    ...
    this.testAgain = function() {
        this.help = function() {
            console.log("help");
        };
    };
};

// Create object of Cms
var md = new Cms();

// Create object of testAgain
var x = new md.testAgain();

// Now call the function
x.help();
(function(window) {
    var Cms = function () {
         this.test = function () {
             console.log("Hello");
         };
         this.testAgain = function () {
             this.help = function() {
                 console.log("Help");
             };
         };
    };
    window.Cms = Cms;
})(window);

// Create the object
var md = new Cms();
// Call the function test
md.test(); // Hello

// Create the object of testAgain using object of Cms 
var x = new md.testAgain(); // Hello again

// Call the function help
x.help(); // Help
// Create a object
var Cms = {};
Cms.test = function() {
    console.log("Hello");
};

// Create a nested objects here
Cms.testAgain = {};

Cms.testAgain.help = () {
    console.log("Help");
};
Cms.test(); // Hello
Cms.testAgain.help(); // Help
(function(window) {
     var Cms = {};
     Cms.test = function () {
          console.log("Hello");
     };
     Cms.testAgain = {};
     Cms.testAgain.help = function () {
          console.log("Hello again");
     };

     window.Cms = Cms;
})(window);

// Directly call the functions
Cms.test(); // Hello
Cms.testAgain.help(); // Help
(function(window) {
     var Cms = {
         test: function () {
             console.log("Hello");
         },
         testAgain: {
             help: function () {
                 console.log("Hello again");
             },
         },
     };

     window.Cms = Cms;
})(window);

// Directly call the functions
Cms.test(); // Hello
Cms.testAgain.help(); // Help

passing arguments to JavaScript function inside input field vs. from inside function


Tag : javascript , By : ugufugu

wish helps you It makes your html markup easier to read (and your js code). It (moreso) decouples your code from your markup. An even better approach would be to bind an event listener to the input by targeting the id. That way you have NO js in your markup.
edit to respond to comment: I was referring to the 2nd example (calling a function) being better, but overall it's better to do event binding. There are various methods to do it, here is an example:
<input type="password" name="pw1" id="pw1"/>

// ...

document.getElementByID('pw1').onkeyup = function() { 
  // do stuff
}

How to trigger javascript function, inside a javascript function, by function's argument?


Tag : javascript , By : somebody

wish help you to fix your issue i want to run a function, inside another function dynamically... , You could simply test r and call each function as needed.
if (r === 'a') {
    a(s);
} else if (r === 'b') {
    b(s);
}
var commands = {
    a: function(item){
        alert("aA");
    },

    b: function(item){
        alert("bB");
    }
};

var x = function (r, s) {
    var command = commands[r];

    if (typeof command === 'function') {
        command(s);
    }
};

x('a', 'foo'); // alerts `aA`
x(a, 'foo'); // calls `a` as `r`, passing 'foo' along

Why does the function name inside a named function in JavaScript no longer refer to the function itself?

I hope this helps you . Consider the following named function: , When you do:
var g = f
var g = function () {
    return f.apply(this, arguments);
}

Function inside function vs function returns function in JavaScript


Tag : javascript , By : Philofax

will be helpful for those in need I am studying JavaScript and I can't understand this. ,
Out2(); outputs nothing in console. What I am doing wrong?
//  vv-------- These call `Out2`   
Out2()();
//    ^^------ These call the function referenced returned by `Out2`
var f = Out2(); // `f` is now a reference to the `In2` function
f();            // This calls `In2`

it helps some times The code starts out with var warper being declared.
And then warper variable equals a function inside a function? Why isn't it the usual call of function Warper(), but its inside another function?
