js传参数

Question

<% String teachername=request.getParameter("teachername");%>
window.parent.frames("main").location.href="account.jsp?user_id=teachername";
想让main框架显示account.jsp，并且传递user_id这个参数，这个参数是在jsp页面中接受到的变量teachername，不知道这个赋值给user_id应该怎么写？直接这样写不对，应该如何把变量teachername的值赋给user_id，传递给account.jsp呢？

Answer 1

window.parent.frames("main").location.href="account.jsp?user_id=<%=teachername%>";

Answer 2

window.parent.frames("main").location.href='account.jsp?user_id=<%request.getParameter("teachername");%>';

Answer 3

直接将teachername赋值给user_id的话，错误提示，无法识别teachername，teachername是在jsp中request接收到的，在js中不识别
<% String teachername=request.getParameter("teachername");%>

Answer 4

<% String teachername=request.getParameter("teachername");%>
var teachername = <%=teachername%>
window.parent.frames("main").location.href="account.jsp?user_id="+teachername;

Answer 5

if 有request才生成那个frame就行了

Answer 6

嗯 直接带入JSP 的变来那个给JS 就可以
