JS「for in」error IE7/8

Question

我正在使用jQuery驗證插件爲我的網站中的某些表單。但是其中一種形式的驗證不適用於IE7和8，但其他形式使用相同的驗證腳本。我試圖調試，發現問題出在showErrors部分，當我通過使用「for in」JS循環errorMap時，show object不支持錯誤。任何想法如何得到修復？

下面是HTML我有

<form name="donate" id="form1" action="https://www.xxxx.xxx.xx/api/help" method="POST" target="_top">  
      <input type="hidden" name="face" id="faceinput" style="clear: both; margin:0; padding:0;"> 
      <input type="hidden" name="image" id="imageinput" style="clear: both; margin:0; padding:0;"> 
      <h3>Thank you for helping! </h3> 
      <h4>Please fill out the following details.</h4>  
      <label>Name: </label> 
      <input type="text" name="fullname" id="fullname" class="required" /> 
      <div class="clearfix"></div> 
      <label>Email: </label> 
      <input type="text" name="email" id="email" class="required email" /> 
      <div class="clearfix"></div> 
      <label>Amount: </label> 
      <input type="text" name="amount" id="amount" class="required number minStrict" /><input type="button" id="submitBtn" value="Donate" /> 
      <div class="clearfix"></div> 
      <div id="error" style="display:none;"> 
       Oops! The minimum amount to donate is $6. Don't wish to donate? Please click on the close button on the top right hand corner instead. 
      </div> 
     </form> 

的JavaScript

$('#form1').validate({ 
       onkeyup: false, 
       focusInvalid: false, 
       rules : { 
        amount : { 
         required : true, 
         number  : true, 
         minStrict : 5 
        } 
       }, 
       messages : { 
        fullname: "Please fill out your name", 
        email: {required:"Please fill out your email address",email:"Invalid email address"}, 
        amount: {required:"Please fill out amount to donate",number:"Invalid amount",minStrict:"Minimum amount is 6$"} 
       }, 
       showErrors: function(errorMap, errorList) { 
        alert('here'); 

        for(error in errorMap){ 
         alert(error); 
         /*if(error=="fullname" || error=="email" || error=="amount"){ 
          //if(errorMap[error]=='Minimum amount is 6$') { 
           //$('div#error').show(); 
          //} 
          //else { 
           $(':text[name='+error+']').val(errorMap[error]).addClass('error');//append err msg in all text field and hightlight 
           $('div#error').hide(); 
          } 
         }*/ 
        } 
       } 
      }); 

$('#submitBtn').click(function(){ 
      if($("#form1").valid()){ 
       alert('here'); 
       $('div#error').hide(); 
       $('#form1').submit(); 
      } 
     }); 

錯誤

SCRIPT438：對象不支持此屬性或方法 validate.js，行26字符5

通過添加var error來修正...

的（在errorMap VAR誤差）{//

Answer 1

我不知道爲什麼，但使用

for(var error in errorMap){ 

似乎張貼在評論解決您的問題...
