1.json类型的字符串转换为json对象及取值
1 var jsonString = '{"bar":"property","baz":3}'; 2 var jsObject = JSON.parse(jsonString); //转换为json对象 3 alert(jsObject.bar); //取json中的值
2.json对象转为json类型的字符串
var json = [Object obj]; var st = JSON.stringify(json); //转换为json类型的字符串
alert(st) //可以看到json对象里面的字段名
3.json数组类型的字符串转换为json及取值 和json对象转换为转换为json字符串
//json数组类型字符串取值 var jsonStr = '[{"id":"01","open":false,"pId":"0","name":"A部门"},{"id":"01","open":false,"pId":"0","name":"A部门"},{"id":"011","open":false,"pId":"01","name":"A部门"},{"id":"03","open":false,"pId":"0","name":"A部门"},{"id":"04","open":false,"pId":"0","name":"A部门"}, {"id":"05","open":false,"pId":"0","name":"A部门"}, {"id":"06","open":false,"pId":"0","name":"A部门"}]'; var jsonObj = JSON.parse(jsonStr);//转换为json对象 for(var i=0;i<jsonObj.length;i++){ alert(jsonObj[i].id); //取json中的值 } console.log(jsonObj) var jsonStr1 = JSON.stringify(jsonObj) console.log(jsonStr1+"jsonStr1")
