function strToJson(str){
var json = eval_r('(' + str + ')');
return json;
}?>

Copy code

Don’t forget the parentheses on both sides of str. Method two, new Function form

function strToJson(str){
var json = (new Function("return " + str))();
return json;
}?>

Copy code

Method 3, use global JSON object

function strToJson(str){
return JSON.parse(str);
}?>

Copy code

Currently in IE8(S)/Firefox3.5+ /Chrome4/Safari4/Opera10 has implemented this method.

When using JSON.parse, you must strictly abide by the JSON specification. For example, attributes need to be enclosed in quotation marks, as follows: var str = '{name:"jack"}'; var obj = JSON.parse(str); // --> parse error The name is not enclosed in quotes. When using JSON.parse, an exception is thrown in all browsers and the parsing fails. The first two methods are fine.
