How to parse JSON easily?
I have some JSON encoded strings and I need to easily parse them. Any ideas how to do this? I am a noob i开发者_C百科n javaScript and I can't do it myself. I read that parsing json is really hard.
Please help!
JSON is valid Javascript, so you can eval() it:
var data = eval(json);
However it's safer to use JSON.parse()
[docs], when this function is available:
var data = JSON.parse(json);
So you could do something like this:
if (window.JSON) {
data = JSON.parse(json);
} else {
data = eval('('+json+')');
}
Note the use of parenthesis in eval(). See @CMS's comment and this.
You could also use an existing library, like this one (adds JSON.parse on browsers that do not have it).
If you are using jQuery, use $.parseJSON()
[docs].
JSON.parse()
is defined in most Javascript environments these days.
try to take a look at http://www.json.org/js.html. You need something like:
var myObject = JSON.parse(myJSONtext, reviver);
