当用户按下回车键时,我正在尝试从输入框中获取值。我不需要任何按钮。如何实现?
test.php
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
</head>
<body>
<form action="#" method="GET" enctype="multipart/form-data">
<center>
<input name="quan" align="middle" type="text" id="quan" placeholder="quan" title="If You Want Change Quantity Then Type Here" size="4">
</center>
</form>
<script type="text/javascript">
$(document).ready(function(){
var model=$('#quan').val();
console.log(model);
});
</script>
</body>
</html>
onChange()
事件,但这取决于你想对该值做什么。我会选择常规的表单提交
