我是 PHP 和 JavaScript 的新手。我想验证表单,如果表单输入字段正确,则将其发送到 php 外部脚本。我试过这样的事情:
<head>
<script type="text/javascript">
function Validate(){
var x=document.forms["form"]["firstname"].value;
var y=document.forms["form"]["lastname"].value;
var z=document.forms["form"]["age"].value;
if(x==null || x=="") {
alert("Input name!");
} else if(y==null || y=="") {
alert("Input surname!");
} else if(z==null || z=="") {
alert("Input age!");
} else {
// IS IT POSSIBLE TO SEND FORM HERE FORM VARIABLES TO PHP SCRIPT?
}
}
</script>
</head>
<body>
<form name="forma" action="validate.php" method="post" onSubmit="return Validate()">
Firstname: <input type="text" name="firstname">
Lastname: <input type="text" name="lastname">
Age: <input type="text" name="age">
<input type="submit">
</form>
</body>
</html>
