Ajax请求传递数组参数

var ids = [];
        var rows=$("#tt").datagrid("getSelections");
        for(var i=0; i<rows.length; i++){
            ids.push(rows[i].phonenumber);
            }
       $.ajax({
            async : false,
            cache : false,
            traditional: true,//防止深度序列化
            type : 'POST',

                ids:ids
            },
            url : "personalInfoController.do?SendMSG",// 请求的action路径
            error : function() {// 请求失败处理函数
            },
            success : function(data) {
