在 struts 2 的对话框上显示错误消息? [英] Showing error message on dialogue box in struts 2?

问题描述

我在 Struts 2 中有一个登录表单，其中包含用户名和密码字段.我想要的是当用户提交表单并且如果它不是有效用户时，我想在对话框中显示错误消息(而不是在登录表单本身中显示错误消息).struts 2 中是否有任何可用的标签，或者有​​人可以指出类似的简短示例?

i have a login form in Struts 2 which has username and password field. what i want is when user submit the form and if it is not a valid user, i want to show the error message in a dialogue box (instead of showing the error message in login form itself). Is there any tag available in struts 2 for this or somebody can point me to similar kind of brief example?

推荐答案

把这个放在你的登录页面(你回到这里是正确的，登录无效?)

put this in your login page(you are returning here right, on invalid login?)

<script>
   <s:if test="hasActionErrors()">
        showDialog("<s:actionerror/>");
   </s:if>
function showDialog(msg){
  //your logic to show dialog goes here
}
</script>
