IE中的单选按钮执行更改功能，但不显示为已检查的jquery

Question

我根据是否检查某些内容添加/删除类，并且它在firefox中运行正常，但IE不会显示复选框的值。触发更改/单击事件，但单选按钮实际上不显示选择，这会导致验证失败。知道发生了什么吗？

以下是更改css的js函数的代码：

function CheckHandlingUnit() {
    var flag = true;

    //Material Number
    if ($("#ContentPlaceHolder2_MatNum_TB").val() == "") {
        $("#ContentPlaceHolder2_MatNum_TB").addClass("TBDecoRed");
        $("#ContentPlaceHolder2_MatNum_TB").removeClass("TBDecoNone");
        flag = false;
    }
    else {
        $("#ContentPlaceHolder2_MatNum_TB").addClass("TBDecoNone");
        $("#ContentPlaceHolder2_MatNum_TB").removeClass("TBDecoRed");
    }

    //Description
    if ($("#ContentPlaceHolder2_Des_TB").val() == "") {
        $("#ContentPlaceHolder2_Des_TB").addClass("TBDecoRed");

        flag = false;
    }
    else {

        $("#ContentPlaceHolder2_Des_TB").removeClass("TBDecoRed");
