前端js拼接Json串

前端js拼接json串

示例1：数组里面含对象

<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);
</script>

组成的json串：[{"group":0,"param":["one","two","three"]},{"group":1,"param":["one","two","three"]},{"group":2,"param":["one","two","three"]}]

示例2：对象里面含数组

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);

组成的json串：{"name":"jack","age":25,"data":[{"0":"abc"},{"1":"abc"},{"2":"abc"}]
