Question

As I’ve got errors in IE7 – I should to take a closer look at JS file – written before …(by others).

at this point I’m not sure about anything, so I’d like to ask you – from my point of view is this wrong (aslo spacing can cause problems, I think) – but it is done all over the site:

(function ($) {
    $(document).ready( function() {
          //the code
    });
})(jQuery);

oh and yes, the error in IE8:

HTML Parsing Error: Unable to modify the parent container element
before the child element is closed (KB927917) – which make me think
the JS is in error.

I know that this is a silly question, but thanks for your answer.

Answer 1

I’ve always seen it like this. This will wait until the document is loaded before running any scripts.

$(function() {
  //the code
});

If you need to use another library that would cause collisions with the $ that jQuery uses, use this

jQuery.noConflict();

Have a look at the $.noConflict() documentation here.
