使用 Struts2 JQuery 日期选择器标签获取未捕获的 TypeError 错误
[英]Getting Uncaught TypeError errors using Struts2 JQuery datepicker tag
问题描述
I have a Struts 2 application with UI built using bootstrap and am trying to get JQuery datepicker working using struts2 jquery tag library.
我有一个带有使用引导程序构建的 UI 的 Struts 2 应用程序，并且正在尝试使用 struts2 jquery 标记库使 JQuery 日期选择器工作。 I am using <sj:head compressed="true" jqueryui="true" /> to include JQuery CSS and JS libraries.我正在使用<sj:head compressed="true" jqueryui="true" />来包含 JQuery CSS 和 JS 库。 Below is what gets included using sj:head :以下是使用sj:head包含的内容：
<script type="text/javascript" src="/struts/js/base/jquery-1.11.0.min.js"></script>
<script type="text/javascript" src="/struts/js/base/jquery.ui.core.min.js?s2j=3.7.1"></script>
<script type="text/javascript" src="/struts/js/plugins/jquery.subscribe.min.js?s2j=3.7.1"></script>
<script type="text/javascript" src="/struts/js/struts2/jquery.struts2.min.js?s2j=3.7.1"></script>
<script type="text/javascript">
$(function () {
jQuery.struts2_jquery.version = "3.7.1";
jQuery.scriptPath = "/struts/";
jQuery.ajaxSettings.traditional = true;
jQuery.ajaxSetup({
cache: false
});
jQuery.struts2_jquery.require("js/struts2/jquery.ui.struts2.min.js?s2j=3.7.1");
});
</script>
<link id="jquery_theme_link" rel="stylesheet"
href="/struts/themes/smoothness/jquery-ui.css?s2j=3.7.1" type="text/css"/>
Below is the code related to datepicker in JSP:下面是 JSP 中与 datepicker 相关的代码：
<%@ taglib prefix="sj" uri="/struts-jquery-tags"%>
<div class="form-group row">
<label class="col-sm-2 control-label">From</label>
<div class="col-sm-4">
<sj:datepicker id="fromDate" displayFormat="m/d/y" showOn="focus" name="startDate"></sj:datepicker>
</div>
<label class="col-sm-2 control-label">To</label>
<div class="col-sm-4">
<sj:datepicker id="toDate" displayFormat="m/d/y" showOn="focus" name="endDate"></sj:datepicker>
</div>
</div>
<script>
$(function() {
$("#fromDate").datepicker({
dateFormat: 'yy-mm-dd',
maxDate: 0,
changeYear: true
}).attr('readonly', 'readonly');
$("#toDate").datepicker({
dateFormat: 'yy-mm-dd',
maxDate: 0,
changeYear: true
}).attr('readonly', 'readonly');
});
</script>
The fields are getting displayed fine and seems to be working fine as well.这些字段显示得很好，似乎也工作正常。 However, I am getting the following errors in console:但是，我在控制台中收到以下错误：
Uncaught TypeError: Cannot set properties of undefined (setting 'version')

I cannot figure out what am I getting wrong here that is causing these errors.我无法弄清楚导致这些错误的原因是什么。 I tried removing the sj:head and instead included the libraries manually but that didn't work either.我尝试删除sj:head并手动包含库，但这也不起作用。

The wrong version of jQuery framework is loaded.加载了错误版本的 jQuery 框架。
<script type="text/javascript" src="/struts/js/base/jquery-1.11.0.min.js"></script>
Don't load jQuery library twice on the same page.
<script src="... ">
the second time you load it with第二次加载它
<sj:head/>
You should include <sj:head/> tag in the body of the <head> tag.您应该在<head>标记的正文中包含<sj:head/>标记。
If you use the <sj:head> tag then you can customize it to use different version of jQuery.如果您使用<sj:head>标签，那么您可以自定义它以使用不同版本的 jQuery。
