[SOLVED] Parsing JSON

[jjacquay712]

What is the best way to parse JSON from an ajax request? I have heard that using eval() can be insecure. Are the any other ways to do it? If so can you give an example?

 

                          Thanks, John

what do you mean parse JSON?...to get data from it?

 

thats extremely simple...its just like an array in PHP:

 

<script type="text/javascript">
Simple Array:
var data = {"key1":"value1", "key2":"value2"};
alert(data['key2']);//will alert "value2"

Multi-Dimensional Array
var data = {"key1":"value1", "key2":{"key1ofKey2":"value1extended", "key2ofKey2":"value2extended"}};
alert(data['key2']['key1ofKey2']);//will alert "value1extended"
</script>

Anything JavaScript-related will never be fully secured. Not PHP or anything will be 100% secured. It's fine to use eval IMO.

Do you mean your ajax call returns a string?

you could try json_parse() from json.org
