[英]Writing a custom validation rule
I'm needing to write my own javascript rules to validate a form. 我需要编写自己的JavaScript规则来验证表单。
I have a field named code
and I need a special validation to it: This field have exactly 13 positions. 我有一个名为code
的字段,我需要对其进行特殊验证:该字段正好有13个位置。 The first and second are letters and the last and penultimate one are letters too. 第一个和第二个是字母,最后一个和倒数第二个也是字母。 The other positions (3-11) are numbers. 其他位置(3-11)是数字。 So, how can I validate this field with these conditions? 那么,如何在这些条件下验证此字段?
<html>
<head>
<script type="text/javascript"
src="javascript/jquery-1.8.2.min.js" >
</script>
<script type="text/javascript"
src="javascript/jquery.validate.min.js" >
</script>
</head>
<body>
<form id="meu_form" action="" method="post" >
Code:<br />
<input type="text" name="code" id="code" /><br />
<input type="submit" value="Save" />
</form>
</body>
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('#meu_form').validate({
rules:{
code:{
required: true,
minlength: 13
maxlength: 13
}
},
messages:{
code:{
required: "Required field.",
minlength: "Exactly 13 length."
}
}
});
});
</script>
</html>
使用正则表达式:
/^[A-Z]{2}[0-9]{10}[A-Z]$/i
