JSP page Pass Value

Function:

Page A1 pass a value: ZSDWH, to the B page, then to the C page, then the C page then return the value to b page, b page back to the A1 page.

Page A2 pass a value: YWZX, to the B page, then to the C page, then the C page then return the value to b page, b page back to the A2 page.

(This is only for example A1-->B--C;C-->B-->A1)

Steps:

One, A1 page, value: ZSDWH assigned to RequestType

Second, according to the Struts configuration file, find the Shiftnetflowinfo method in the background action,

Third, add code in method Shiftnetflowinfo:

String RequestType = Request.getparameter ("RequestType");//Accept the value of RequestType from the foreground page: ZSDWH

Request.setattribute ("RequestType", RequestType);//Bring the value back to the foreground page after this method executes (temporarily named B page here)

Iv. based on the struts configuration file, find the page that jumps after the last method execution: shiftnetflowinfo.jsp

In the B page (shiftnetflowinfo.jsp), add the following code:

Vi. find the Snfhistory method in the background action based on the struts configuration file

Seven, add code in method Snfhistory:

String RequestType = Request.getparameter ("RequestType");//Accept the value of RequestType from the foreground page: ZSDWH

Request.setattribute ("RequestType", RequestType);//Bring the value back to the foreground page after this method executes (temporarily named C page here)

Eight, according to the Struts configuration file, find the last method to jump after the page: snfhistoryinfo.jsp

Nine, in the C page (snfhistoryinfo.jsp) Add the following code (too long to intercept the diagram, paste the code directly):

<c:if test= "${requesttype== ' ZSDWH '}" >
<input type= "button" name= "button" id= "button" value= "return" class= "Submit" onclick= "window.location.href=" <SKC: Go name= "shiftnetflow_shiftnetflowinfo" defaulturi= "shiftnetflow.do?requesttype=zsdwh" ></skc:go> "/>
</c:if>

Comments:

The last requesttype=zsdwh of the second line of code is to bring the value back to the background action method: Shiftnetflowinfo

According to the Struts configuration file:

　　

Bring the value back to page B (shiftnetflowinfo.jsp)

Ten, in the B page, add Judgment method, if the value equals ZSDWH, click the Back button, according to the struts configuration file, will execute method: Getshiftnetflowsheettoedit

<c:if test= "${requesttype== ' ZSDWH '}" >
<input type= "button" name= "button" id= "button" value= "return" class= "Submit" onclick= "window.location.href=" <SKC: Go name= "Shiftnetflow_getshiftnetflowsheettoedit" defaulturi= "getshiftnetflowsheettoedit.do" </skc:go> "/ >
</c:if>

PS: Resolved, two pages (page A1, page A2), call the same method to jump to the same page (page b), click the Return button, you can jump back to the original page.
