我使用 ajax 验证来验证以下内容
<tr>
<td width="20" style='color: red'>
<img src="images/icon-star.png" width="16" height="16" />
</td>
<td id="lblCustomBillNo" style="width: 15%" class="searchCriteriaCellLbl">
The custom Bill Number
</td>
<td width="5" class="searchCriteriaCellLbl">:</td>
<td class="searchCriteriaCellVal">
<s:textfield id="customBillNo" name="customBillNo" size="20" maxlength="24" style="width: 200px" />
</td>
<td class="errorFlag" style="color: red" valign="middle">
<s:fielderror fieldName="customBillNo" />
</td>
</tr>
<tr>
<td width="20" style='color: red'>
<img src="images/icon-star.png" width="16" height="16" />
</td>
<td id="lblBillNo" style="width: 15%" class="searchCriteriaCellLbl">
<s:property value="%{getText('billNo')}" />
</td>
<td width="5" class="searchCriteriaCellLbl">:
</td>
<td class="searchCriteriaCellVal">
<s:textfield label="billNo" id="billNo" name="billNo" size="20" maxlength="24" style="width: 200px" />
</td>
<td class="errorFlag" style="color: red" valign="middle">
<s:fielderror fieldName="billNo" />
</td>
</tr>
<tr>
<td width="20" style='color: red'>
<img src="images/icon-star.png" width="16" height="16" />
</td>
<td id="lblCarrierNo" style="width: 15%" class="searchCriteriaCellLbl">
The carrier Number
</td>
<td width="5" class="searchCriteriaCellLbl">:
</td>
<td class="searchCriteriaCellVal">
<s:textfield label="carrierNo" id="carrierNo" name="carrierNo" size="20" maxlength="24" style="width: 200px" />
</td>
<td class="errorFlag" style="color: red" valign="middle">
<s:fielderror fieldName="carrierNo" />
</td>
</tr>
我对 gobal i18n 文件中的错误使用以下国际化
errors.required=${getText(fieldName)} requireddd
和这个验证文件
<validators>
<field name="customBillNo">
<field-validator type="requiredstring" short-circuit="true">
<param name="trim">true</param>
<message key="errors.required" />
</field-validator>
</field>
<field name="billNo">
<field-validator type="required" short-circuit="true">
<message key="errors.required" />
</field-validator>
</field>
<field name="carrierNo">
<field-validator type="required" short-circuit="true">
<message key="errors.required" />
</field-validator>
</field>
</validators>
我把这个javascript用来使用ajax验证
function validate(){
//document.all.loading.style.display = 'block';
var searchUrl = 'AddEnteringApproval_approval';
var params = '';
var elemArray = document.mainForm.elements;
for (var i = 0; i < elemArray.length;i++)
{
var element = elemArray[i];
var elementName= element.name;
if(elementName=='formAction')
continue;
params += '&' + elementName+'='+ encodeURIComponent(element.value);
}
params += '&struts.enableJSONValidation=true&struts.validateOnly=true';
createXmlHttpObject(); // this is my function that prepare ajax
sendRequestPost(http_request,searchUrl,false,params);
postValidation();
}
function postValidation() {
var form = $('#mainForm');
var text = http_request.responseText;
//clear previous validation errors, if any
StrutsUtils.clearValidationErrors(form);
alert(text)
//get errors from response
//var text = request.responseText;
var errorsObject = StrutsUtils.getValidationErrors(text);
//show errors, if any
if(errorsObject.fieldErrors)
{
StrutsUtils.showValidationErrors(form, errorsObject);
}
else
{
//good to go, regular submit
form.submit();
}
}
/* This is one of the functions that doesn't work using the simple theme, so I redefined it.
This can be changed to clear the previous errors, as it does in the commented example
cleaning the errors on divErrors.
As I am just showing the messages with alerts I don't need to clear anything,
but the method still need to be redefined, even if it is empty.
*/
StrutsUtils.clearValidationErrors = function(form, errors) {
//clear the div errors
//$('#divErrors').empty();
}
/* This method is responsible to show the messages.
The original versions works with the xhrml and css-xhtml theme but doesn't work with the simple theme
so I override the method with another implementation that shows the messages using alerts.
You can change the implementation to show the messages as you want,
but as the previous method this has to be redefined.
*/
StrutsUtils.showValidationErrors = function(form, errors) {
if(errors.fieldErrors)
{alert((errors.fieldErrors))
for(var fieldName in errors.fieldErrors)
{
alert("errors.fieldErrors[fieldName] " + errors.fieldErrors[fieldName]);
for(var i = 0; i < errors.fieldErrors[fieldName].length; i++)
{
alert('Field ->' + fieldName + '\nError -> ' + errors.fieldErrors[fieldName][i]);
}
}
}
};
但是当我执行代码时，我没有在警报消息框中显示有组织的 JSON 文本，字段名称与错误消息中的不同，第二个字段名称丢失，第三个字段名称被剪切（即 carrierNo 变为 rNo ）。
你能帮助我吗。我希望 JSON 错误中的字段名称与错误消息文本匹配
我只是想出了问题所在，但我不知道它为什么会发生以及为什么会发生。它总是删除前 6 个字符。为什么会这样
