One shouldn't use scriptlets in JSP, you can easily do it using struts2 tags.
不应在 JSP 中使用 scriptlet，您可以使用 struts2 标签轻松实现。
Change your Javascript in JSP as follows :
在 JSP 中更改您的 Javascript 如下：
function checkedRadioForDelete(f) {
var chx = document.getElementsByTagName('input');
for ( var i = 0; i < chx.length; i++) {
if (chx[i].type == 'radio' && chx[i].checked) {
var con = confirm("<s:text name="msg.confirm"/>");
if (con != true) {
} else {
f.action = "MyAction.action";
f.submit();
}
return true;
}
}
alert("<s:text name="msg.alert"/>");
return false;
}

Note: Updating my answer based on comments.
In your JSP page you can use scriptlets within javascript function (or tag)
function checkedRadioForDelete(f) {
var confirmMessage = '<%= properties.getProperty("confirm.message") %>';
var alertMessage= '<%= properties.getProperty("alert.message") %>';
var chx = document.getElementsByTagName('input');
for ( var i = 0; i < chx.length; i++) {
if (chx[i].type == 'radio' && chx[i].checked) {
var con = confirm(confirmMessage);
if (con != true) {
} else {
f.action = "MyAction.action";
f.submit();
}
return true;
}
}
alert(alertMessage);
return false;
}

You can load properties with javascript using messageResource.jslibrary created by me.
您可以使用我创建的messageResource.js库使用 javascript 加载属性。
1) Include messageResource.js.
1) 包含 messageResource.js。
<script src="messageResource.min.js"></script>
2) Change javascript as follows.
2）按如下方式更改javascript。
// initialize messageResource.js
messageResource.init({
// path to directory containing properties files
filePath : 'path/resource'
});
function checkedRadioForDelete(f) {
// get values from properties files
var confirmMsg = messageResource.get('msg.confirm', 'fileName');
var alertMsg = messageResource.get('msg.alert', 'fileName');
var chx = document.getElementsByTagName('input');
for ( var i = 0; i < chx.length; i++) {
if (chx[i].type == 'radio' && chx[i].checked) {
var con = confirm(confirmMsg);
if (con != true) {
} else {
f.action = "MyAction.action";
f.submit();
}
return true;
}
}
alert(alertMsg);
return false;
}

If anyone needs help for a Web Application, please see my answerthat explains the simplest method to read properties from a property file in the project directory. In summary, you will be able to populate some selected properties in hidden inputs and then read the hidden input value from JavaScript.
如果有人需要有关 Web 应用程序的帮助，请参阅我的回答，其中解释了从项目目录中的属性文件读取属性的最简单方法。总之，您将能够在隐藏输入中填充一些选定的属性，然后从 JavaScript 读取隐藏的输入值。
