我有一个 JSP 页面。我正在使用struts2。这是我的 JSP 页面
如您所见，上面有一个表格，另一个手风琴显示了一些项目。显示组件列表的组件。并有一个添加按钮。当我单击添加按钮时，它将调用一个 Ajax 调用并返回 HTML，我将其设置为DIV并将其显示为弹出表单。
输入数据后，单击保存，它将调用 Ajax 并保存到数据库。然后它将重定向到另一个动作以获取更新的列表并将列表返回给 ajax。我在组件选项卡中显示的结果。
这是工作。现在，在弹出表单中，一些字段是必需的，如果不输入这些字段，它将调用动作类（动作验证器.xml 文件用于验证所需字段。）并将返回错误，但作为其 ajax 调用，结果数据将在组件选项卡内设置。
（此处显示的错误消息是另一个表单的错误。但此表单也会显示相同的错误消息。在该错误消息下方，表单也会显示。所有将在组件选项卡内）我希望显示错误结果以相同的弹出形式。
jQuery 阿贾克斯
$(document).on('click', ".saveRow", function(){
var formId=$(this).closest("form").attr("id");
var form = $("#"+formId);
var htmlId=formId;
htmlId=getDivId(htmlId);
form.submit(function () {
$('.saveRow').html('Saving...').fadeIn();
var urlAction=form.attr('action');
var dataFields=form.serialize();
callActionUsingAjax(urlAction, dataFields, function (data) {
var ajaxActionResult=ajaxResult(data);
setHTMLContent(ajaxActionResult,htmlId);
$('.popUpForm').dialog("close");
});
return false;
});
});
function callActionUsingAjax(urlAction, dataFields, callback)
{
$.ajax({
type: "post",
url: urlAction,
data: dataFields,
success: function (data) {
callback(data);
}
});
}
function ajaxResult(data)
{
var ajaxResult= $('<div/>').html(data),
$ajaxContent = ajaxResult.find('#ajaxContent');
var ajaxActionResult=$('<div/>').html($ajaxContent);
ajaxActionResult.find('#ajaxContent').removeClass("crudItems");
ajaxActionResult.find('#resultContent').removeClass("includestyle");
ajaxActionResult.find('#ajaxContent').find("#footer").remove();
return ajaxActionResult;
}
function setHTMLContent(ajaxActionResult,htmlId) {
$("#"+htmlId).html(ajaxActionResult);
$("#"+htmlId).height(315);
}
alert(data);如果我用整个 html 文本给它警报，那么在 ajax 成功中。我试过了，它用"undefined"alert(data.redirect)发出警报。
我的 struts.xml
<action name="saveDimComponent"
class="com.vxl.appanalytix.webapp.action.DimComponentAction"
method="save">
<result name="input">/WEB-INF/pages/dimComponentForm.jsp</result>
<result name="cancel" type="redirectAction">dimComponents</result>
<result name="delete" type="redirectAction">dimComponents</result>
<result name="success" type="redirectAction">dimComponents</result>
</action>
（即，如果输入结果，它应该显示有错误的弹出表单）
