<form action="" method="post" autocomplete="off">

<input type=submit id="submit">
在上面的代码中，我想在Javascript的帮助下重定向页面，但是window.location = 'dws_Support.php'在else部分不起作用，但是当我们在else部分发出警告时，它会显示但不会重定向到'dws_Support.php'。请帮助。
尝试使用window.location.href='dws_Support.php'
你不需要用javascript重定向表单，问题来自于你的属性操作表单，所以使用以下代码:
<script src="js/jquery.js"></script>
<script>
$(document).ready(function() {
$("#submit").click(function() {
var value = document.getElementById("txt_sketch_no").value;
var process_id = document.getElementById("process_id").value;
var length = value.length;
if (length <= 0) {
alert("Please Enter the sketch card");
window.location = 'sketch_screen.php';
} else {
window.location = 'dws_Support.php';
}
});
});
</script>
</head>
<body style="background-color: #73C5E1" >
<div class="container">
<div class="alert alert-success" id="alert_box">
<input type="hidden" name="process_id" id="process_id" value="12">
<label> Enter the Sketch Card No : </label>
<input type="text" id="txt_sketch_no" name="txt_sketch_no">
<input type = "submit" id="submit">
</div>
</div>
</body>
这是您的失败:您正在收听click，但submit事件的形式刹车您的逻辑。这是固定的:
$(document).ready(function() {
$("form").on('submit', function(e) {
e.preventDefault();
var value = document.getElementById("txt_sketch_no").value;
var process_id = document.getElementById("process_id").value;
var length = value.length;
if (length <= 0) {
alert("Please Enter the sketch card");
window.location = 'sketch_screen.php';
} else {
window.location = 'dws_Support.php';
}
});
});
很高兴你找到了答案，但是你的编码没有问题，你只是错过了返回false;重定向后. .
<script src="jquery-1.4.js"></script>
<script type="text/javascript">
<!--
$(document).ready(function() {
$("#submit").click(function() {
var value = document.getElementById("txt_sketch_no").value;
var process_id = document.getElementById("process_id").value;
var length = value.length;
if (length <= 0) {
alert("Please Enter the sketch card");
window.location = '/sketch_screen.php';
return false;
} else {
window.location = 'dws_Support.php';
return false;
}
});
});

希望这能解决你的问题。:)
