带有多个选择框的jQuery Validate插件

问题描述

我正在使用jQuery Validate来验证我的表单.问题是我有一个带有多个选择框的表单(动态数字)，并且它具有动态名称-> answers[$question['id']]

I'm using jQuery Validate to validate my form. The problem is that I have a form with multiple select boxes (dynamic number) and it has a dynamic name -> answers[$question['id']]

当您有一个固定的名称时，我已经看过一些脚本，您可以使用它来寻址所有输入字段，像这样.

I've seen some scripts when there's a fixed name you can use that to address all the input fields like so.

$('#form').validate({
    rules: {
        "answers[]" = "required"
    }
});

但是在我的示例中这是不可能的，有什么想法吗?谢谢！

But in my example this is not possible, Any ideas? Thanks!

推荐答案

首先，

不是"answers[]" = "required"

它是"answers[]": "required"

注意冒号代替等号.

$('#form').validate({
    rules: {
        "answers[]": "required"
    }
});

第二，这只会将required规则分配给具有name="answers[]"的单个字段.

Secondly, that would only assign the required rule to a single field with name="answers[]".

如果要使用name="answers[1]"，name="answers[2]"，name="answers[3]"等轻松地将此规则分配给多个字段，则需要执行以下两项操作之一...

If you want to easily assign this rule to multiple fields with name="answers[1]", name="answers[2]", name="answers[3]", etc., then you'll need to do one of two things...

1)内嵌声明required规则...

1) Declare the required rule inline...

使用class:

<input type="text" name="answers[1]" class="required" />
<input type="text" name="answers[2]" class="required" />
<input type="text" name="answers[3]" class="required" />

使用HTML5或

<input type="text" name="answers[1]" required="required">
<input type="text" name="answers[2]" required="required">
<input type="text" name="answers[3]" required="required">

还有jQuery:

$('#form').validate(); // initialize the plugin

2)或使用rules()方法将规则动态分配给以answers开头的name的所有字段:

2) Or assign the rule dynamically using the rules() method to all fields with a name starting with answers:

$('#form').validate(); // initialize the plugin

// assign the rules
$('input[name^="answers"]').each(function() {
    $(this).rules('add', {
        required: true
    });
});
