在我的表单中，根据所需的单选按钮选项显示新字段。我想仅在需要相应的单选按钮时才验证这些字段。
如果选择了第一个选项，则需要地址，城市，州和邮政编码。 如果选择第二个选项，则只需要日期 如果选择第3个选项，则需要上述所有字段。
我在这里发布了一个关于我迄今为止所有内容的小提琴：http://jsfiddle.net/aEgk8/1/
我想要做的是找出一种方法来编写规则，如果选中一个选项或另一个选项，则需要字段。像
这样的东西 address: {
required: "#ship-address:checked or #ship-both:checked"
},
city: {
required: "#ship-address:checked or #ship-both:checked"
}
我还需要更新选择的规则，因此仅在选中其中一个选项时才需要它们。我怎样才能做到这一点？这是我第一次尝试实现这样的东西，所以我愿意接受建议。
我在使用1.3.2库（我无法更改或删除）的网站上实现此功能，并且字段上的显示/隐藏将无法使用，因此我必须运行更新的库在平行下。当我只引用jQuery 1.3.2时，我的显示/隐藏功能不起作用。
这是我的代码：
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="http://jzaefferer.github.com/jquery-validation/jquery.validate.js" type="text/javascript"></script>
<script type="text/javascript">
jQuery.validator.setDefaults({
debug: true,
success: "valid"
});
</script>
<script>var $j = jQuery.noConflict(true);</script>
<script type="text/javascript">
$j(document).ready(function() {
$j.validator.addMethod("valueNotEquals", function(value, element, arg){
return arg != value;
}, "Please select a new shipping date.");
$j('#pancettaForm').change(function () {
$j('#address,#address2,#new-ship-date').hide();
if ($j('#ship-address').prop('checked')) {
$j('#address, #address2').show();
}
else if ($j('#ship-date').prop('checked')) {
$j('#new-ship-date').show();
}
else if ($j('#ship-both').prop('checked')) {
$j('#address, #address2, #new-ship-date').show();
}
});
$j( "#pancettaForm" ).validate({
rules: {
address: {
required: "#ship-address:checked"
},
newShip: {
valueNotEquals: "- Select -"
}
},
messages: {
updateShip: {
required: "Please tell us how you would like to update your order."
},
SelectName: {
valueNotEquals: "Please select a new shipping date."
}
}
});
});
</script>

答案 0 :(得分：0)
address: {
required: {
depends: function(element) {
return $('#ship-address').is(':checked') || $('#ship-both').is(':checked');
}
}
},
city: {
required: {
depends: function(element) {
return $('#ship-address').is(':checked') || $('#ship-both').is(':checked');
}
}
}
至于选择，我不确定你提到哪些，但基于依赖性，这个想法是一样的。
答案 1 :(得分：0)
我相信这可能是您正在寻找的选项（虽然我没有在您的jQuery版本中对此进行测试）：http://jqueryvalidation.org/category/methods/#example:-makes-details-required-only-if-#other-is-checked
来自jquery.validation文档：
示例：仅在选中#other时才需要制作详细信息。
<html>
<head>
<meta charset="utf-8">
<title>Makes details required only if #other is checked.</title>
<link rel="stylesheet" href="http://jqueryvalidation.org/files/demo/site-demos.css">
</head>
<body>
<form id="myform">
<label for="other">Check to make next field required</label>
<input id="other" type="checkbox">
<br>
<input id="details" name="details">
<br>
<input type="submit" value="Validate!">
</form>
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="http://jqueryvalidation.org/files/dist/jquery.validate.min.js"></script>
<script src="http://jqueryvalidation.org/files/dist/additional-methods.min.js"></script>
<script>
// just for the demos, avoids form submit
jQuery.validator.setDefaults({
debug: true,
success: "valid"
});
$( "#myform" ).validate({
rules: {
details: {
required: "#other:checked"
}
}
});
</script>
</body>
</html>
如果你有很多字段，这个解决方案虽然重复，但仍然比使用上面提到的depends方法更清晰。
答案 2 :(得分：0)
我认为只需添加,即可：
address: {
required: "#ship-address:checked, #ship-both:checked"
},
city: {
required: "#ship-address:checked, #ship-both:checked"
}
