问题描述
我有这种形式，输入的名称相同，但id相似(递增).
I have this form with inputs with the same name but similar (incremental) ids.
我希望表格验证人名是否存在，年龄必须是必填项.
I want the form to validate if there is a name on person, the age must be mandatory..
现在发生的是，只有第一个输入是强制性的.
What happens now is that only the first input is mandatory.
这是我的代码:
<html lang="en">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js"></script>
</head>
<body>
<form id="people">
<div class="section">
<input id="person1" name="person" class="person" type="text" placeholder="First Name" />
<input id="age1" name="age" class="age" type="text" placeholder="Age" />
</div>
<div class="section">
<input id="person2" name="person" class="person" type="text" placeholder="First Name" />
<input id="age2" name="age" class="age" type="text" placeholder="Age" />
</div>
<div class="section">
<input id="person3" name="person" class="person" type="text" placeholder="First Name" />
<input id="age3" name="age" class="age" type="text" placeholder="Age" />
</div>
...
<input type="submit" id="submit" name="submit" value="Add" />
</form>
<script type="text/javascript">
$(function(){
$('#people').validate();
$('#submit').click(function(){
$('[id^="person"]').each(function(){
if ($(this).val().length>0){
//alert($(this).val());
//alert($(this).parent().find('.age').val());
$(this).rules('add', {
required: true,
minlength: 2,
messages: {
required: "Specify the person name",
minlength: "Minimum of 2 characters"
}
});
$(this).parent().find('.age').rules('add', {
required: true,
number: true,
messages: {
required: "Must have an age",
number: "Specify a valid age"
}
});
}
});
});
});
</script>
</body>
推荐答案
jQuery Validator插件不支持即名即用的多个字段.您需要编辑插件的源代码，以按所需方式检查字段.
The jQuery Validator plugin doesn't support multiple fields with the same name out-of-the-box. You'll need to edit the source of the plugin to check the fields the way you want.
