ajax传参在ie8中的问题

    /*获取隐藏域数据，并将数据转为数组*/
        var Ids = x.val();
        var eachParamer = Ids.substring(0,Ids.length-1).split(",");
        $.ajax({
            url: m+"/selfprogram/selfProgram/showParam?paramIds="+Ids,",
            type: "post",
            dataType:"json",
            data:{"paramIds":Ids},
            success: function (data) {
                var obj = eval(data);           .......

参数传递，在chrome下好着，但在ie8下报错，不能传中文

解决办法如下：

 function queryByParam(x,y,z,m){
        /*获取隐藏域数据，并将数据转为数组*/
        var Ids = x.val();
        var eachParamer = Ids.substring(0,Ids.length-1).split(",");
        $.ajax({
            url: m+"/selfprogram/selfProgram/showParam",
            type: "post",
            dataType:"json",
            data:{"paramIds":Ids},
            success: function (data) {
                var obj = eval(data);
                var str = "";        ....
