jQuery Validator取决于方法未定义 [英] jQuery Validator depends method undefined

问题描述

Firebug向我显示以下内容:

Firebug is showing me the following:

从以下验证器初始化开始:

From the followin Validator initialization:

$("#surveyForm").validate({
    errorPlacement: function(error, element) { 
    if ( element.is(":radio") ) {
        error.appendTo ( '#' + element.attr('name') + '_multiError' ); 
        } else if ( element.is(":checkbox") ) {
        error.appendTo ( '#' + element.attr('name') + '_multiError' );
        } else {
        error.appendTo( element.parent() );
        }
},
    rules: {
     ans_23: {
         depends: function(element) {
           return $("#ans_22:checked")
         }
 }
   },
   debug: true
});

该规则基于规则此处下的第二个示例.

The rule is based on the second example under rules here.

所引用的HTML看起来像这样

The HTML being referenced looks like this

<td class='two_columns'>
<label>
<input type='radio' name='rad_22' id='ans_22' class='required' value='Yes'  />  Other
</label>
<input type='text' name='ans_23' id='ans_23' value='' class='' />
</td>

任何人都知道为什么depends方法将是未定义的吗?

Anyone know why the depends method would be undefined?

脚注:我还尝试使用规则添加方法(参见下文)进行此操作.当调用validate()并且ans_23没有获得"required"类时，该表单已经过验证，没有任何错误.

Footnote: I also tried doing this using the rule add method (see below). That form validated and threw no errors when validate() was called and ans_23 did not gain "required" class....

$("#surveyForm").rules("add", {
  ans_23: {
    required: "#ans_22:checked"
  }
});

推荐答案

我看到您的评论回复将我的评论转换为答案...所以去了:

I saw a comment reply from you to convert my comment to an answer... so here goes:

$("#surveyForm").validate({
    errorPlacement: function(error, element) { 
    if ( element.is(":radio") ) {
        error.appendTo ( '#' + element.attr('name') + '_multiError' ); 
        } else if ( element.is(":checkbox") ) {
        error.appendTo ( '#' + element.attr('name') + '_multiError' );
        } else {
        error.appendTo( element.parent() );
        }
},
    rules: {
     ans_23: {
         required: {
           depends: function(element) {
             return $("#ans_22:checked");
           }
         }
 }
   },
   debug: true
});
