Javascript 获取单击编号的值以更新单击的数据

我们有一个表单，我们可以单击表单顶部的数字来加载相应的数据，更具体地说，我可以在数据库的表中有4个输入，当我单击数字2（数据的id）时，它就会加载数据。我们这样做了，但是现在我们想要更新单击的数据，直到现在我们还找不到一种方法来获取正确的numberid并将其放在update语句中

下面是单击的函数和UPDATE语句的代码

                $("#updateEdu").click(function () {
                    $("#idE").css("display", "none");
                    var r = parseInt($("#idE").val(), 10) + 1;
                    $("#idE").val(r);
                });
                $('[data-row-ide]').click(function (e) {
                    e.preventDefault();
                    var fileName = 'addCV.php?idEdu='; //"addCV.php" the name of this file in your project, the "?" starts the GET parameters, idWork= sets the key for the GET parameter  
                    var id = $(this).data('row-ide'); // this gets the id that we stored in the link's data attribute
                    var url = fileName + id; // then we add that id as the value for the "idWork" key
                    window.location = url; // esentially refresh this page with the id set as a GET parameter and make use of the logic we already have to load the info

要在jquery中获取elements属性的值，可以使用attr函数，如下所示：

$element.attr'attributeName'

所以你应该改变：

var id = $(this).data('row-ide');

进入

在函数$'[data row ide]'中，单击函数e{}

var id = $(this).attr('row-ide');
