Question

我有一个动态表，其中包含一些数据。在我的表中有一个名为Edit的选项，通过单击SideNav正在打开的编辑选项。我想从表中获取该特定行并想要放置这些信息进入我的身边。

我的HTML和JS文件在下面。

/index.html

<table class="table-bordered mytable">
                     <thead class="table-head">
                     <tr>

function editUser() {
    var par = $(this).parent().parent();
    var tdName = par.children("td:nth-child(1)");
    var tdEmail = par.children("td:nth-child(2)");
    var tdAddress = par.children("td:nth-child(3)");

    //want to edit/update userinformation through this "api/updateUser/v1:id" using put method 

}

function myDelete() {
    alert();
};

Answer 1

使用jquery

function myEdit(elem)
{
    $('#user_name').val($(elem).parent().parent().find('td:nth-child(1)').html());
    ...
    /* fill other fields */
}

Answer 2

这是完美而干净的解决方案：

$('tbody tr').click(
function(){
  var name = $(this).find("td:nth-child(1)").html();
  var email = $(this).find("td:nth-child(2)").html();
  var addr = $(this).find("td:nth-child(3)").html();
$('#user_name').val(name);
  $('#email_id').val(email);
  $('#address').val(addr);
});

如何使用jQuery，JavaScript和AJAX选择表行数据并将其发送到Edit Modal以获取更新数据？
