Common page Jump methods in HTML/jsp

First:
<Script language = "JavaScript" type = "text/JavaScript">
Window. Location. href = "login. jsp? Backurl = "+ window. Location. href;
</SCRIPT>

Second:
<Script language = "JavaScript">
Alert ("return ");
Window. History. Back (-1 );
</SCRIPT>

Third:
<Script language = "JavaScript">
Window. navigate ("Top. jsp ");
</SCRIPT>

Fourth:
<Script language = "JavaScript">
Self. Location = "top.htm ";
</SCRIPT>

Category 5:
<Script language = "JavaScript">
Alert ("illegal access! ");
Top. Location = "XX. jsp ";
</SCRIPT>

 

Sixth:

Servlet jump --> request. getrequestdispatcher ("/WEB-INF/pages/error. jsp"). Forward (request, response );

 

7:

Because the above redirects are all under webroot, or the complete URL address is known. if HTML or JSP is stored in the WEB-INF, in the case of struts, you can get the complete URL address by configuring the struts path, do not use struts to achieve page Jump under the WEB-INF...
