jquery - Calling a javascript function from another .js file

Question

I have two external .js files. The first contains a function. The second calls the function.

file1.js

$(document).ready(function() {

    function menuHoverStart(element, topshift, thumbchange) {

        ... function here ...

    } 

});

file2.js

$(document).ready(function() {

    setTimeout(function() { menuHoverStart("#myDiv", "63px", "myIMG"); },2000); 

});

The trouble is that this is not running the function. I need the two separate files because file2.js is inserted dynamically depending on certain conditions. This function works if I include the setTimeout... line at the end of file1.js

Any ideas?

The problem is, that menuHoverStart is not accessible outside of its scope (which is defined by the .ready() callback function in file #1). You need to make this function available in the global scope (or through any object that is available in the global scope):

function menuHoverStart(element, topshift, thumbchange) {
    // ...
}

$(document).ready(function() {
    // ...
});

If you want menuHoverStart to stay in the .ready() callback, you need to add the function to the global object manually (using a function expression):

$(document).ready(function() {
    window.menuHoverStart = function (element, topshift, thumbchange) {
        // ...
    };
    // ...
});
