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

<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);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"]}]-->
