In general... How can I make a call on a function of an external java script file?
More specific...
- In the head tag i have
<script type="text/javascript" src="JScript/FontSize.js"></script>
The external javascript file, (that i would like to call)
FontSize.jscontains the following functions.function checkCookie() function setCookie(c_name, value, expiredays) function getCookie(c_name) function increaseFontSize() function decreaseFontSize()`The FontSize.js is located at the
~/Jscript/directory
I guess the body on load should contain something like
<body onload="/JScript/Fontsize.js/checkCookie()">
Of course nothing works as it should because, i do not know how to make the call to a function to an external js file

Reset to default 13You just call it as if it were local :)
<body onload="checkCookie()">
Or, do it in script:
window.onload = checkCookie;
When you declare a function and it's not in another object/namespace, it's just globally available, and you can call it as if it immediately preceded your current code. By default these functions will be on the window object, you can see a short demo here.
For example (doesn't matter where this function's defined, external or not):
function myFunc() { alert('hi'); }
myFunc();
window.myFunc(); //same call, unless there's *another* myFunc in a local-er scope
