以下代码适用于jsfiddle但不适用于localhost,你能帮帮我吗？ script src="/uploads/allimg/210615/210431DJ-0.jpg" type="text/javascript"/script script $('.puankontrol').change(function() { var x = $(this).val() * 1; if((x 1) ||
<script src="http://img.558idc.com/uploadfile/allimg/210615/210431DJ-0.jpg" type="text/javascript"></script>
<script>
$('.puankontrol').change(function() {
var x = $(this).val() * 1;
if((x < 1) || (x > 5))
{
$(this).val(3);
alert("Please enter value between 1-5!");
}
});
</script>
</head>
<body>
<form>
<input class="puankontrol" type="text" name="puan"/><BR>
<input class="puankontrol" type="text" name="puan"/><BR>
<input class="puankontrol" type="text" name="puan"/><BR>
</form>
<div id="other">
Trigger the handler
</div>
</body>
</html>
`
尝试$(document).ready(function(){
//change function declaration.
});
也使用< script type =“text / javascript”>用于添加脚本标记.
