Accessing functions in javascript

Hi Experts,

I want to access functions defined in javascript file (foo.js) from sample.js  file. These javascript files reside in the same folder.

[subtitle]foo.js[/subtitle]

function foo() {

}

foo.ftype.Isempty=function(){

}

//Returns a value in specific format

foo.Telformat=function(param){

}

//Returns true / false

foo.ValidateTel=function(param){

}

//Returns true / false

foo.Isnumber=function(param){

}

[subtitle]sample.js[/subtitle]

function testall (someparam)
{

//Here I need to call foo.js file helper functions

}

Open in new window

to use function from another file you need to load it with your browser

<script src="/path/to/same/folder/foo.js"></script>
<script src="/path/to/same/folder/sample.js"></script>

Open in new window

Basically foo.js contains generic functions that  will return boolean / some values.So in the sample.js file I have a function called testall and  want to invoke generic fucntions.

sample.js

function testall (someparam)
{

//Here I want to invoke / call the functions defined in the foo.js file 

}

Open in new window

I did n't get you. I am c# developer ,suppose if I have a class (common.cs) and have methods for  Format,reverse of string,Isnumber etc. I can invoke these methods in other classes .In sample.cs file  to access common methods , I will  instantiate common class and pass parameters to these  methods as required.In javascript ,How can I achieve this?

In JavaScript you must load the script in the page before the script using the fonction inside. You don't have to do anything else. Don't need to have a référence inside simple.JS.

@leakim971 is correct.  Javascript methods are different than something like C#.  C# (for web pages) runs on the server.  Javascript runs in the browser.  When a web page is opened that contains javascript, the browser must load all of the files because javascript itself isn't allowed to directly access files on the client or the server.  It can only work with what the browser has loaded.

Mat be my question is not clear,let me put in this way actually I am doing model validation in angularjs and checking  user input is valid or not.Suppose if user enter's invalid data in the text box and  have a function in sample.js file that takes input data from form and checks valid or invalid.To do this I want to invoke common  methods(IsNumber,ValidateTel etc) and return true (no msg) or false (Show error msg in the UI).In this case, I don't have to do anything?

This page http://docs.angularjs.org/tutorial/step_02 shows part of how angularjs is used.  It show including the necessary javascript files in the web page so that the application code has access to the functions that are needed.  You do have to include the necessary files in script links so they will be loaded by the browser and be available.
