jQuery 验证器不验证 onkeyup

Question

在阅读了一堆问题并对其应用“解决方案”后，我发现 jQuery 验证器未验证 onkeyup。默认情况下，应该如此。我通过下载新文件来确保源代码没有被修改，什么都没有。

版本:jquery 1.10.2

Validation code:

/* check form */
$("#registerForm").validate({
/*  rules: {
    primaryPhone: {skip_or_fill_minimum: [2,'.firstPhoneSet']},
    contactPrimary: {skip_or_fill_minimum: [2,'.firstPhoneSet']},
    secondaryPhone: {skip_or_fill_minimum: [2,'.phoneNum2']},
    contactSecondary: {skip_or_fill_minimum: [2,'.phoneNum2']}
  }*/
    onkeyup: function(element)
    {
      $(element).valid();
    },
    errorElement: "span",
    rules: 
    {
        birthMonth: 
        {
          skip_or_fill_minimum: [3,'.dob']
        },
        birthDay: 
        {
          skip_or_fill_minimum: [3,'.dob']
        },
        birthYear: 
        {
          skip_or_fill_minimum: [3,'.dob']
        },
        resume: 
        {
          required: true,
          extension: "txt|doc|docx"
        },
        gender: 
        {
          required: true
        },
        ohlWhy:
        {
          required: true,
          wordCount: ['30']
        },
        coping:
        {
          required: true,
          wordCount: ['20']
        },
        intensity:
        {
          required: true,
          wordCount: ['20']
        }
    }
});

注意:

我已经尝试过运行此代码而无需

onkeyup: function(element)
{
  $(element).valid();
},

我还有一个 addClassRules 方法调用:

jQuery.validator.addClassRules({
  field: 
  {
    required: true,
    minlength: 2
  },
  zip: 
  {
    required: true,
    digits: true,
    minlength: 5,
    maxlength: 5
  },
  years: 
  {
    required: true,
    digits: true,
    minlength: 1,
    maxlength: 2
  },
  phoneNum: 
  {
    required: true,
    phoneUS: true
  },
    phoneNum2: 
  {
    required: false,
    phoneUS: true
  },
  dropList: 
  {
    required: true
  },
  dob: 
  {
    date: true,
    required: true
  },
});

什么也没有。这是我在另一个问题上找到的解决方案，但这给了我错误:

未捕获类型错误:对象 [object Object] 没有方法“有效”

这看起来很奇怪，因为 .valid() 是一个验证器方法。

HTML 有很多输入字段:

<form id="registerForm" action="index.cfm" method="post">
    <fieldset>
      <legend>Basic Information</legend>
      <div class="insets">
          <label class="control-label" for="fName">First Name: </label>
          <input type="text" name="fName" id="fName" class="field" value="<cfoutput>#session.fName#</cfoutput>" /><br />
          <label class="control-label" for="lName">Last Name: </label>
          <input type="text" name="lName" id="lName" class="field" value="<cfoutput>#session.lName#</cfoutput>" /><br />
          <label class="control-label" for="nick">Nickname: <span class="optional">*optional</span></label>
          <input type="text" name="nick" id="nick" value="<cfoutput>#session.nick#</cfoutput>" /><br />
      </div>

    <input type="hidden" value="2" id="volType" name="volType" />

          </label>

          <label class="radio inline" for="contactSecondaryNo">
            <input type="radio" name="contactSecondary" id="contactSecondaryNo" value="no" <cfif IsDefined("session.contactSecondary") AND session.contactSecondary EQ "no">checked</cfif> />No
          </label>

        </div>
      </fieldset>

      <!--- if rcc or web --->
      <div class="form-actions" id="non-shlButton"> 
          <button type="submit" style="float:right;" class="btn btn-success">Continue to Step 2 &#187;</button>
      </div>

      <!--- if shl --->
      <div class="form-actions" id="shlButton">
          <button type="submit" style="float:right;" class="btn btn-primary">Submit My Application</button>
      </div>
    </div> <!--- end show after choice --->
  </form>

所以我的问题是:为什么我的脚本只验证 onfocusout 和 onsubmit ？ (当它是同一类型的多个问题的解决方案时，为什么我会收到该错误？)

Answer 1

将其添加到验证器配置中:

onkeyup: function( element, event ) {
        if ( event.which === 9 && this.elementValue(element) === "" ) {
            return;
        } else {
            this.element(element);
        }
    },

它覆盖了插件的 onkeyup 函数。它应该有效。

现在验证插件以不同的方式工作。它首先等待用户输入文本，然后验证它，当某个字段被验证一次时，onkeyup 就可以正常工作。
