问题描述
我在静态表单中使用 Yii 用户端验证，它很棒.但我不知道如何为 ajax 加载的元素添加验证器.
I'm using Yii user side validation in static forms and it's great. But I don't know how to add validators for ajax loaded elements.
我有一个简单的表单小部件，我想通过 AJAX 将更多的输入字段加载到其中(小 jQuery 脚本没有问题).但我不知道如何为加载的元素添加 Yii javascript 验证器 - 我的意思是自动创建的 JS 验证器，如:
I have simple form widget and I would like to load few more input fields into it via AJAX (that's not problem with small jQuery script). But I don't know how to add Yii javascript validators for loaded elements - I mean auto created JS validators like:
<script type="text/javascript">
/*<![CDATA[*/
jQuery(function($) {
$('#newsletter-form-footer').yiiactiveform({'validateOnSubmit':true,'validateOnChange':false,'afterValidate':Form.handleByAjax,'attributes':[{'id':'NewsletterForm_emailaddress','inputID':'NewsletterForm_emailaddress','errorID':'NewsletterForm_emailaddress_em_','model':'NewsletterForm','name':'emailaddress','enableAjaxValidation':false,'clientValidation':function(value, messages, attribute) {
if($.trim(value)=='') {
messages.push(" VALIDATOR_REQUIRED");
}
if($.trim(value)!='' && !value.match(/^[a-zA-Z0-9!#$%&'*+/=?^_`{|}~-]+(?:.[a-zA-Z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?.)+[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?$/)) {
messages.push(" VALIDATOR_EMAIL");
}
}}]});
});
/*]]>*/
</script>
有什么方法可以添加或删除验证器吗?
Is there any way how to add or remove that validators?
推荐答案
这有点棘手...如果你想用 yiiactiveform 来做，你必须:
This is little bit tricky... If you want to do it using yiiactiveform, you have to:
- 向验证添加字段，或
- 从验证中删除字段
我的建议是:
创建您自己的 JavaScript 验证函数(您可能想在此处复制 yii 的验证代码)
Create your own JavaScript validation functions (you may want to copy yii's validation code here)
$('#newsletter-form-footer').submit(function() {
return MyValidator.validate();
});
当您将字段加载到表单中时
When you load a field into the form
//You have to get rulesORoptions
// along with fieldName from your ajax request.
MyValidator.add(fieldName, rulesORoptions);
当您从表单中删除字段时
When you Remove a field out of the form
MyValidator.remove(fieldName);
此处为 MyValidator 代码...
MyValidator code here...
var MyValidator = {
fields: {},
add: function(fieldName, rulesORoptions) {
this.fields[fieldName] = rulesORoptions;
},
remove: function(fieldName) {
delete this.fields[fieldName];
},
validate: function() {
var success = true;
for(var fieldName in this.fields) {
for(var rule in this.fields[fieldName]) {
if( eval('MyValidator.'+rule+'($("#'+fieldName+'").val())') == false ) {
$("#'+fieldName+'_em_").html("validation failed (some error text, rulesORoptions may contain error text )");
success = false;
}
}
}
return success;
},
/* Validation methods are here,
copy the javascript validation code from Yii
*/
email: function(value) {
if($.trim(value)!='' && !value.match(/^[a-zA-Z0-9!#$%&'*+/=?^_`{|}~-]+(?:.[a-zA-Z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?.)+[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?$/)) {
return false;
}
return true;
},
required: function(value) {
if($.trim(value)=='') {
return false;
}
return true;
},
number: function(value) {
if(/*copy yii validation code */) {
return false;
}
return true;
},
.....
.....
};
