Question

我对ajax表单提交有一些问题

$("#send").on("click", function() {

$.ajax({
            type: "POST",
            url: "ads_process.php",
            data: $("#ads").serialize(),
            success: function(){
                if(data == "true") {
                    $("#ads").fadeOut("fast", function(){
                        //$(this).before("<p><strong>Success! Your message has been sent, thanks!</strong></p>");
                        setTimeout("$.ads.close()", 2000);
                        });
                    }
                }
            });
        });

一个页面有数据列表，有一个注释按钮，当它点击弹出窗口打开时。我写评论和提交，但问题是，父页面刷新我不想刷新父页面我只想提交数据，插入数据库和弹出窗口将被关闭和数据将显示在父页面上。

任何人都可以帮助我

Answer 1

通过使用prevent default，您可以停止表单刷新页面，如下所示： http://api.jquery.com/event.preventDefault/

$("#send").on("click", function(events) {
    events.preventDefault();
    $.ajax({
                type: "POST",
                url: "ads_process.php",
                data: $("#ads").serialize(),
                success: function(){
                    if(data == "true") {
                        $("#ads").fadeOut("fast", function(){
                            //$(this).before("<p><strong>Success! Your message has been sent, thanks!</strong></p>");
                            setTimeout("$.ads.close()", 2000);
                            });
                        }
                    }
                });
            });

Answer 2

试试此代码

$("#send").on("click", function(e) {
e.preventDefault();
$.ajax({
            type: "POST",
            url: "ads_process.php",
            //Specify the datatype of response if necessary
            data: $("#ads").serialize(),
            success: function(data){
                if(data == "true") {
                    $("#ads").fadeOut("fast", function(){
                        //$(this).before("<p><strong>Success! Your message has been sent, thanks!</strong></p>");
                        setTimeout("$.ads.close()", 2000);
                        });
                    }
                }
            });
        });

首先让我这样说：
你绑定了一个事件监听器，但DOM可能还没有准备好，但是：将你的代码包装在$(document).ready(function(){});回调中然后：setTimeout("$.ads.close()", 2000);是不好的做法。 setTimeout应该传递对函数对象的引用，而不是字符串，将其替换为：

setTimeout(function()
{
    $.ads.close();
}, 2000);

接着
实际上，您需要preventDefault事件，以防止其默认行为被执行。虽然这并不能阻止事件通过dom传播/冒泡。如果单击的元素是提交按钮，则表单可能仍会被提交（并且页面将被刷新）。
要阻止这种情况发生，请同时调用preventDefault()和stopPropagation()，或者（因为您使用的是jQuery），您只需返回false，这与调用这两种方法完全相同

但是，在您的情况下，我会将事件处理程序附加到表单，并侦听submit事件：

$(document).ready(function()
{
    $('#form').on('submit', function(e)
    {
        $.ajax({
            type: 'post',
            url: 'your/url',
            data: $(this),
            success: function(data)
            {//do stuff
                console.log(data);
            }
        });
        return false;
        //or
        e.preventDefault();
        e.stopPropagation();//strictly speaking, not required here
    });
});

当客户端使用击键（如输入）提交表单时，应禁用正在提交的表单。
