json字符串、对象、数组之间的转换方法

json字符串转化成json对象

1.jquery的方法: var jsonObj =$.parseJSON(jsonStr)

2.js 的方法: var jsonObj =JSON.parse(jsonStr);    

json对象转化成json字符串

js方法var jsonStr1 =JSON.stringify(jsonObj)

<script type="text/javascript">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 = $.parseJSON(jsonStr);var jsonObj =JSON.parse(jsonStr)
        console.log(jsonObj)
     var jsonStr1 =JSON.stringify(jsonObj)
     console.log(jsonStr1+"jsonStr1")
    </script>

json对象转化成数组

<script type="text/javascript">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 = $.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>
