我的问题是每当我点击'ForgetPassword'或'ResetPassword'时，应该调用相应的java脚本函数，而是指向loginvalidation.jsp？这是什么问题...... ??

Answer 1

看起来pwd（）是你正在调用的函数吗？

<input type="radio" name="pwdissue" onclick="pwd(this)" value="forget"/>Forget Password

哪个重定向到loginpagevalidation.jsp

function pwd(pwdissue){
    var pwddecision=pwdissue.value;
    //alert(pwddecision);
    window.open('loginpagevalidation.jsp?option='+pwddecision,target="_self");
}

我错过了什么吗？

Answer 2

您的pwd函数会打开一个'loginpagevalidation.jsp'窗口;那就是你说不想要发生什么？

那些应该是链接，而不是单选按钮。你真的在JSP中做SQL工作吗？由于各种原因，这不应该通过任何人的代码审查:(

为了将来参考，最好只包含与问题实际相关的代码，而不是整个页面的源转储。我删除了一些不重要的HTML。

Answer 3

这是javascript函数pwd taht调用url loginpagevalidation.jsp，因此您的函数确实被执行，但也会立即重定向到新的url。这不是你想要的吗？
