我想只在用户确认时执行一些脚本
像这样的示例代码
if 'confirm' is clicked, then $confirm = true;
if($confirm)
{
some script
}
else
{
other script
}
?>
有两个按钮'确认'和'丢弃'。如果单击确认,则$ confirm = true;

假设您有两个这样的按钮
<input type="button" name="confirm" id="confirm" value="confirm">
<input type="button" name="discard" id="discard" value="discard">
您可以使用jquery事件处理程序来获取单击哪个按钮
$(document).ready(function() {
$("#confirm").on('click',function(){
alert('Confirm clicked');
//If you need to communicate with the server the do an ajax call here
});
$("#discard").on('click',function(){
alert('Discard clicked');
//If you need to communicate with the server the do an ajax call here
});
});
您可以检查HERE

您可以使用php,使用环境php变量提取字段状态,您只需制作一个公式并将一些数据发送到您的webserver脚本文件。
<?php
$confirm = $_POST["name_of_the_button"]
if(isset($confirm))
{
some script
}
else
{
other script
}

我用两个文件制作了它:
文件:form.php
<html>
<head>
<title>Button test</title>
<script type="application/javascript">
function ajaxObj()
{
var xmlHttp=null;
try
{
// Browsers Firefox, Opera 8.0+, Safari;
xmlHttp=new XMLHttpRequest();
}
catch(e)
{
try
{
// Browser Internet Explorer;
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e)
{
try
{
// Other browsers
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e)
{
// Your browser does not suport XMLhttp object
alert('Your browser does not suport XMLhttp object');
return false;
}
}
}
return xmlHttp;
}
function doQuery(id)
{
xmlHttp=ajaxObj();
if(xmlHttp==null)
{
alert('Your browser does not suport XMLhttp object');
return;
}
xmlHttp.open("POST","check.php",true);
var send = 'id='+id;
xmlHttp.onreadystatechange=function()
{
if (xmlHttp.readyState==4 && xmlHttp.status==200)
{
document.getElementById("output").innerHTML=xmlHttp.responseText;
}
}
xmlHttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlHttp.send(send);
}
</script>
</head>
<body>
<button id="confirmed" name="button" onclick="doQuery(this.id)">Confirm</button>
<button id="declined" name="button" onclick="doQuery(this.id)">Decline</button>
<div id="output"></div>
</body>
</html>
文件check.php:
<?php
$action = $_POST["id"];
$confirm = false;
if($action=="confirmed")
$confirm = true;
else if($action=="declined")
$confirm = false;
else {}
?>

如果你使用javascript然后使用belo: -
if(window.confirm("please confirm"))
{
return true;
// or do Your operation.
}
else{
return false;
// or do Your operation.
}
否则你可以使用jquery。

<input type="button" name="confirm" id="confirm" value="confirm">
<input type="button" name="discard" id="discard" value="discard">
$(document).ready(function() {
$("input:button").on('click',function(){
if($(this).id == 'confirm'){
// put your script here
}else{
// put your script here }
});
});
