json字符串、json對象、數組 三者之間的轉換

 

json字符串轉化成json對象

// jquery的方法 var jsonObj = $.parseJSON(jsonStr) //js 的方法 var jsonObj = JSON.parse(jsonStr)

json對象轉化成json字符串

//js方法 var jsonStr1 = JSON.stringify(jsonObj)

例如

例如：

<script type="text/javascript"> var jsonStr = '[{"id":"01","open":false,"pId":"0","name":"A部門"},{"id":"01","open":false,"pId":"0","name":"A部門"},{"id":"011","open":false,"pId":"01","name":"A部門"},{"id":"03","open":false,"pId":"0","name":"A部門"},{"id":"04","open":false,"pId":"0","name":"A部門"}, {"id":"05","open":false,"pId":"0","name":"A部門"}, {"id":"06","open":false,"pId":"0","name":"A部門"}]'; // var jsonObj = $.parseJSON(jsonStr); var jsonObj = JSON.parse(jsonStr) console.log(jsonObj) var jsonStr1 = JSON.stringify(jsonObj) console.log(jsonStr1+"jsonStr1") </script>

json對象轉化成數組

<script type="text/javascript"> var jsonStr = '[{"id":"01","open":false,"pId":"0","name":"A部門"},{"id":"01","open":false,"pId":"0","name":"A部門"},{"id":"011","open":false,"pId":"01","name":"A部門"},{"id":"03","open":false,"pId":"0","name":"A部門"},{"id":"04","open":false,"pId":"0","name":"A部門"}, {"id":"05","open":false,"pId":"0","name":"A部門"}, {"id":"06","open":false,"pId":"0","name":"A部門"}]'; // var jsonObj = $.parseJSON(jsonStr); var jsonObj = JSON.parse(jsonStr) console.log(jsonObj) var jsonStr1 = JSON.stringify(jsonObj) console.log(jsonStr1+"jsonStr1") var jsonArr = []; for(var i =0 ;i < jsonObj.length;i++){ jsonArr[i] = jsonObj[i]; } console.log(typeof(jsonArr)) </script>
