前端js拼接Json字串,全
示例1:數組裡面含物件
<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);//JSON.stringify() 方法用於將 JavaScript 值轉換為 JSON 字串。 alert(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"]}]
示例2:物件裡面含陣列
var object = {}; var params = []; for(var i = 0; i < 3; i++){ var obj = {}; obj[i] = "abc"; params.push(obj); } object['name'] = 'jack'; object['age'] = 25; object['data'] = params; var json = JSON.stringify(object); console.log(json);
組成的json串:
{"name":"jack","age":25,"data":[{"0":"abc"},{"1":"abc"},{"2":"abc"}]}
