Question

getRowData function in jqgird,I notice that there is a selector look like "$("td", ind)",
I haven’t seen this before, and more weird, It got different results when worked in chrome and firefox.

I known first parameter means select all "td"s,but what’s the use of second parameter?

Answer 1

The second argument is the context, from the docs –

By default, selectors perform their searches within the DOM starting
at the document root. However, an alternate context can be given for
the search by using the optional second parameter to the $() function.

Internally, selector context is implemented with the .find() method,
so $(‘span’, this) is equivalent to $(this).find(‘span’).

From – http://api.jquery.com/jQuery/

So in your example the code will be searching for tds inside the ind object.
