如何将JavaScript对象文字的字符串转换为JavaScript对象文字？

Question

How can I convert the string...

"{ name: 'John' }"

...to an actual JavaScript object literal that will allow me to access the data using its keys (Ie varname["name"] == "John")? I can't use JSON.parse(), since the string is invalid JSON.

Answer 1

You could use eval().

var str = "{ name: 'John' }";
var obj = eval("(" + str + ")");

Answer 2

From the previous question

s="{ name: 'John'}";
eval('x='+s);

Answer 3

Example with new Function

 var str = "{ name: 'John' }"; var fnc = new Function( "return " + str ); var obj = fnc(); console.log(obj.name);
