如何在提交前创建确认弹出式提醒？

Question

当用户点击按钮时，我想将Are you sure you want to delete this comment?作为弹出提醒。那怎么样？

$('button').on('click', function(){

    // show a alert to the user contains "Are you sure you want to delete this comment?"

    if ( /* he pressed "yes" */ ) {
        var id = $(this).attr('id');
        deleteComment(id);
    } else {
        // nothing happens
    }
});

Answer 1

$('button').on('click', function(){

if (confirm("Do you really want to delete?")) {
    var id = $(this).attr('id');
    deleteComment(id);
} else {
    return false;
}
});

Answer 2

超级简单！只需将确认对话框分配给变量

即可

"select top 10 CustomerID from CustList"

由于js是同步的，它将逐行运行代码！确认对话框将在运行后阻止任何内容。

Answer 3

$('button').on('click', function(){

    answer = confirm("Are you sure?")

    if (answer == true) {
        var id = $(this).attr('id');
        deleteComment(id);
    } else {
        // nothing happens
    }
});

Answer 4

这个概念与上面三个答案相同。它将改变您实现逻辑的方式。

$('button').on('click', function(){

   if (confirm("your dialog here") === true ) {
    var id = $(this).attr('id');
    deleteComment(id);
   } else {
    // nothing happens
   }
});
