Functions come up as undefined if I place them in the document.ready() function:
$(document).ready(function(){
function foo()
{
alert('Bar');
}
});
foo(); // Undefined
Why does this happen? I'm sure I'm just in need of some simple understanding :)
Not sure why defining the function with in the scope of ready() is important to you, but you can make it work by declaring foo up front:
<html><head>
<script type=text/javascript src=http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js></script>
<script>
var foo; // Here's the difference
$(document).ready(function(){
foo = function ()
{
alert('Bar');
}
});
</script></head><body>
<input type=button onclick=foo() value=Click me>
</body></html>
Obviously you can't call foo() from the inline script immediately after ready() because the ready() code hasn't yet run, but you can call the function later on.
Just make sure that nothing can try to call foo() before the ready() code has run (or make the initial declaration of foo() a harmless function).
