1. JSON.parse(jsonString): 在一个字符串中解析出JSON对象
| 1 2 3 | varstr = ‘[{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]‘;JSON.parse(str); | 
结果:

2. JSON.stringify(obj) : 将一个JSON对象转换成字符串
| 1 2 3 | varobj = [{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}];JSON.stringify(obj); | 
结果:
| 1 | "[{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]" | 
3. jQuery.parseJSON(jsonString) : 将格式完好的JSON字符串转为与之对应的JavaScript对象 
| 1 2 3 | varstr = ‘[{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]‘;jQuery.parseJSON(str); | 
结果:

4.JSON.parse()和jQuery.parseJSON()的区别:
有的浏览器不支持JSON.parse()方法,使用jQuery.parseJSON()方法时,在浏览器支持时会返回执行JSON.parse()方法的结果,否则会返回类似执行eval()方法的结果,以上结论参考jquery 1.9.1 得出:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 | parseJSON: function( data ) {    // Attempt to parse using the native JSON parser first    if( window.JSON && window.JSON.parse ) {        returnwindow.JSON.parse( data );    }    if( data === null) {        returndata;    }    if( typeofdata === "string") {        // Make sure leading/trailing whitespace is removed (IE can‘t handle it)        data = jQuery.trim( data );        if( data ) {            // Make sure the incoming data is actual JSON            // Logic borrowed from http://json.org/json2.js            if( rvalidchars.test( data.replace( rvalidescape, "@")                .replace( rvalidtokens, "]")                .replace( rvalidbraces, "")) ) {                return( newFunction( "return "+ data ) )();            }        }    }    jQuery.error( "Invalid JSON: "+ data );}, |
