部门表
dept_ID dept_name 1 Account 2 Finance 3 Marketing
这次我在代码中添加了一个对话框。
假设我的部门表只有3条记录。
我的要求如下:
- 单击第一个删除按钮，显示对话框，单击确定，显示部门 ID = 1
- 单击第二个删除按钮，显示对话框，单击确定，显示部门 ID = 2
- 单击第三个删除按钮，显示对话框，单击确定，显示部门 ID = 3
但是，无论我单击哪个按钮，我都会得到未定义的值。
有人可以帮助我吗？
最佳答案
$(this) 位于
var departmentID = $(this).next('input.departmentID').val();
不引用您的 DOM 对象，而是引用当前对话框。
首先创建对 DOM 对象的引用，稍后您可以使用该引用:
$(document).ready(function(){
$(".buttonsPromptConfirmDeleteDepartment").click(function(){
var $box = $(this);
...
...
click: function()
{
var departmentID = $box.parent().find('input.departmentID').val();
alert(departmentID);
}
...
...
});
});
