Question

我想在yii中设置唯一电子邮件ID的验证，但它无法正常工作，所以问题出在哪里。我的表单代码如下：

  <div class="row">
    <?php echo $form->labelEx($model1,'user_email'); ?>
    <?php echo $form->textField($model1, 'user_email', array('maxlength' => 300)); ?>
    <?php echo $form->error($model1, 'user_email', array('clientValidation' => 'js:customValidateemail(messages,this.id)'), false, true);
          $infoFieldFile1 = (end($form->attributes)); ?> 
    <p class="emailUniqueCheck" style="margin-left: 24%; color: red;">    
  </div>

我的ajax代码如下：

<script>
function customValidateemail(messages,id){
    var nameC= '#'+id;  
    var a = $(nameC).val();
    if (a == '') {
        messages.push('Email Id is empty.');
        return false;
    }
    var email = $("#Registration_user_email").val();
    $(".emailUniqueCheck").html('<img alt="Loader" src="/images/loading.gif" />');
    $.ajax({
            url:"<?php echo Yii::app()->request->baseUrl;?>"+"/Supplier/checkUniqueEmail?email="+a,
            data:'req=add_more',
            dataType:'html',
            type:'POST',
            async: false,
            success:function(resp){
                if(resp == 1) {
                $(".emailUniqueCheck").html("Email Already exists.");
                return false;
                } else {
                $(".emailUniqueCheck").html("Proceed.");    
                } 
            },
            error:function(er){
                alert("An error has occured, Please reload/refresh the page and try again.");
            }
        });
}

这里，vaidation适用于空电子邮件意味着if(a == '') { alert('bla bla'); }并且页面也不会在点击提交按钮时提交。（根据需要。）

对于ajax响应验证工作正常但只有return false;不起作用。并提交表格。我尝试了很多东西，但没有工作。任何人都可以帮助我吗？

//Since the call is not an asynchronous , you need to return false after ajax call

var isValid = false;
function customValidateemail(messages, id) {
var nameC = '#' + id;
var a = $(nameC).val();
if (a == '') {
    messages.push('Email Id is empty.');
    return false;
}
var email = $("#Registration_user_email").val();
$(".emailUniqueCheck").html('<img alt="Loader" src="/images/loading.gif" />');
$.ajax({
    url: "<?php echo Yii::app()->request->baseUrl;?>" + "/Supplier/checkUniqueEmail?email=" + a,
    data: 'req=add_more',
    dataType: 'html',
    type: 'POST',
    async: false,
    success: funsuccess(),
    error: funerr()
});
return isValid;
 }
function funsuccess(data, textStatus, jqXHR) {
if (data == 1) {
    $(".emailUniqueCheck").html("Email Already exists.");
    return true;
} else {
    $(".emailUniqueCheck").html("Proceed.");
}
isValid = true;
}
 function funerr(err) {  
 alert("An error has occured, Please reload/refresh the page and try  again;
isValid = true;
}

return false不适用于yii
