JS将各值拼接JSON串小例

通过数组实现

最后调用JSON.stringify(data)方法

[html] view
plain copy

<div id="json" style="width:100%;height:50px;background-color:yellow">  

  

</div>  

  

<script>  

      

    var  params = [];  

    for(var i = 0; i < 3; i++){  

        var param = [];  

        param.push("one");  

        param.push("two");  

        param.push("three");  

        params.push({"group":i,"param":param});  

    }  

      

    var json = JSON.stringify(params); 
  //注意要转字符串

    alert(json);  

      

    var jsonElem = document.getElementById("json");  

    jsonElem.innerHTML = json;  

      

</script>  

  

<!--  

    组成的json串：  

    [{"group":0,"param":["one","two","three"]},{"group":1,"param":["one","two","three"]},{"group":2,"param":["one","two","three"]}]
