JS將各值拼接JSON串小例

通過數組實現

最後調用JSON.stringify(data)方法

<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); 
  //注意要轉字符串
    alert(json);

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

</script>

<!--
    組成的json串：
    [{"group":0,"param":["one","two","three"]},{"group":1,"param":["one","two","three"]},{"group":2,"param":["one","two","three"]}]
