Which is equivalent, but more idiomatic for eval () in jQuery?

Question

What is equivalent to making this call eval('('+responseText+')')in jQuery? I also understand that it is evalnot so safe, so I am looking for something more secure and more idiomatic in jQuery.

Answer 1

Do you really want to execute Javascript code (which will be unsafe to some extent), or are you trying to parse JSON from a string into an object?

If the first, eval () will still be your best bet.

a) JS-:

b) JSON:

$.parseJSON( json )

Answer 4

By design, jQuery intends to improve browser implementation. Since there is no problem with how various browsers implement it eval, it is not processed by jQuery.

Answer 5

$.globalEval()?

The documentation says that it behaves very differently than eval(), but its closest match is if you want to pass your grades through jQuery.
