var str = ‘{"name":"huangxiaojian","age":"23"}‘
var str = ‘[{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]‘; JSON.parse(str);
/*---------------------------------------------------------------------------------*/
2、JSON.stringify(obj) : 将一个JSON对象转换成字符串
var obj = [{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]; JSON.stringify(obj); "[{"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
var str = ‘[{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]‘; jQuery.parseJSON(str);
/*---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------*/
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：
parseJSON: function( data ) { // Attempt to parse using the native JSON parser first if ( window.JSON && window.JSON.parse ) { return window.JSON.parse( data ); } if ( data === null ) { return data; } if ( typeof data === "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 ( new Function( "return " + data ) )(); } } } jQuery.error( "Invalid JSON: " + data ); },
