jQuery 按 ID 和表单组验证

Question

我需要通过id验证而不是输入名称，因为我输入的名称是data[name]。我还有一条规则允许一个或两个字段。

我可以添加带有 id 的规则，但我不能合并这两个规则。有办法吗

<input id="email" type="email" class="form-control contact-method" name="data[email]" placeholder="Email">
<input id="phone" type="text" class="form-control contact-method" name="data[phone]" placeholder="Phone">

JS代码：

$('#requestDemo').validate({  // <- attach '.validate()' to your form
    debug: false,
    errorElement: "span",
    errorClass: "help-block",
    rules: {
        phoneInput: {
            require_from_group: [1, ".contact-method"]
        },
        emailInput: {
            require_from_group: [1, ".contact-method"]
        }
    },

我认为您面临的问题是 name 中的特殊字符，您可以在对象键等情况下使用字符串文字

jQuery(function($) {
  $('#requestDemo').validate({ // <- attach '.validate()' to your form
    debug: true,
    errorElement: "span",
    errorClass: "help-block",
    rules: {
      'data[email]': {
        require_from_group: [1, ".contact-method"]
      },
      'data[phone]': {
        require_from_group: [1, ".contact-method"]
      }
    }
  })
});

<form id="requestDemo" method="post" action="">
  <input id="email" type="email" class="form-control contact-method" name="data[email]" placeholder="Email">
  <input id="phone" type="text" class="form-control contact-method" name="data[phone]" placeholder="Phone">

  <input type="submit" class="button" value="Submit" />
</form>

Answer 2

I also have a rule to allow one or both fields.

当您未在 HTML 标记中的任何位置使用 contact-method class 时，我看不出您的 require_from_group 规则将如何运作。您需要添加此 class...

<input id="email" type="email" class="form-control contact-method" name="data[email]" placeholder="Email">
<input id="phone" type="text" class="form-control contact-method" name="data[phone]" placeholder="Phone">

I need to validate by id and not input name because my input name is data[name]

有两种解决方法...

When the name contains special characters like dots or brackets, you would simply surround the name with quotes...

jQuery(function($) {
    $('#requestDemo').validate({
        ....
        rules: {
           "data[email]": {
                require_from_group: [1, ".contact-method"]
            },
            ....

演示 1：http://jsfiddle.net/umgjLvhd/

使用 the .rules('add') method 而不是 .validate()...

声明规则

$('.contact-method').each(function() {
    $(this).rules('add', {
        require_from_group: [1, $(this)]
    });
});

注意：无论您如何声明规则，input 元素必须仍然包含唯一的 name属性。
