javascript - 使用jquery单击删除按钮后更改行背景颜色

Question

嗨，我有一个表格，在单击该按钮后，该列中有一个删除按钮，该行将突出显示为红色。我一直在尝试一些不同的东西，但它只是不起作用。如何在 ConfirmBox() 方法中更改行的颜色？先感谢您.......................

             <table id="loanSignatoriesTable" class="table table-striped table-bordered bg-light">
                        <thead class="bg-blue">
                            <tr>
                                <th>Emp No.</th>
                                <th>Employee Name</th>
                                <th>Rank</th>
                                <th>Designation</th>
                                <th>Group/Department</th>
                                <th>Signatory Type</th>
                                <th>Default</th>
                                <th>Status</th>
                                <th>Modified Date</th>
                                <th>Action</th>
                            </tr>

                    CallButtonEvent();

您可以在函数参数中传递当前元素对象，然后在函数体中您可以访问调用元素的父 '<tr>' 元素，然后更新其 CSS 属性。使用以下代码更新 ajax 中的渲染属性：

 "render": function (data, type, full, meta) {

                        return '<center>'
                            + '<a href="#" name="idapplication" OnClick="return ConfirmBox(this,' + 
                            data.Id + ');" value="Delete" > Delete <a/>'
                            + '<br/>'
                            + '<a href="#" name="idedit" OnClick="EditItem(' + data.Id + ');" 
                         value="Edit" > Edit <a/>'

                            + '</a>'
                        '</center >';
                         }
                        },

使用以下更新您的功能

function ConfirmBox(Elem, RefID) {

        document.getElementById("hiddenRefID").value = RefID;
        setTimeout(function () {
            if (confirm("Are you sure you want to delete this record?")) {
                let parentTRElement = $(Elem).closest('tr').css('background', 'red');
                $(parentTRElement).css("background-color", "red");
                CallButtonEvent();
            }
            else {

            }
        }, 1);

    }
