Question

我有一个PHP表单，其动作链接是另一个PHP页面，它将用户输入的数据添加到数据库中，然后将它们重定向到另一个页面。

我正在尝试在将PHP表单发送到其操作页面之前显示弹出窗口。我面临的问题是，无论何时按下提交/创建按钮，弹出窗口都会显示一秒钟，然后自动消失。

通过故障排除，我发现问题出现在表单标签中，因为当按钮超出其完美表现的形式时。

我的代码：

<?php
session_start();
?>


<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<style>
#dialogoverlay{
    display: none;
    opacity: .8;
    position: fixed;
    top: 0px;
    left: 0px;
    background: #FFF;
    width: 100%;
    z-index: 10;
}
#dialogbox{
    display: none;
    position: fixed;
    background: #000;
    border-radius:7px; 
    width:550px;
    z-index: 10;
}
#dialogbox > div{ background:#FFF; margin:8px; }
#dialogbox > div > #dialogboxhead{ background: #666; font-size:19px; 
padding:10px; color:#CCC; }
#dialogbox > div > #dialogboxbody{ background:#333; padding:20px; 
color:#FFF; }
#dialogbox > div > #dialogboxfoot{  }
#dialogbox > div > #dialogboxfoot2{ }
</style>
<script>
function CustomAlert(){
this.render = function(dialog){
    var winW = window.innerWidth;
    var winH = window.innerHeight;
    var dialogoverlay = document.getElementById('dialogoverlay');
    var dialogbox = document.getElementById('dialogbox');
    dialogoverlay.style.display = "block";
    dialogoverlay.style.height = winH+"px";
    dialogbox.style.left = (winW/2) - (550 * .5)+"px";
    dialogbox.style.top = "100px";
    dialogbox.style.display = "block";
    document.getElementById('dialogboxhead').innerHTML = "Are you sure?";
    document.getElementById('dialogboxbody').innerHTML = dialog;
    document.getElementById('dialogboxfoot').innerHTML = '<button

    document.getElementById('dialogboxfoot2').innerHTML = '<button

}

似乎你想＆＃34;暂停＆＃34;提交直到用户确认或取消他的请求？很像肯定（）会做什么？

然后它比这更复杂，你必须＆＃34;取消＆＃34;提交首先返回＆＃34; false＆＃34; （比如onclick =＆＃34; Alert.render（＆＃39;您即将创建一个新组。＆＃39;）;返回false＆＃34;或者通过调用event.preventDefault（）（并将事件添加到你的参数）

然后你需要确定你的＆＃34;确认＆＃34;按钮所以它做了一些事情：通过重新提交表单（这次让它去）或者通过重定向或任何其他方法。
