JSP calls the processing result returned by another page.

Description: List page: a page with search criteria.
Selectlist page: displays the data results generated by the List Search conditions.
Because our data List displays two parts, 1: Search for the page part list page. 2: Data Page part selectlist page.
To list the implementation process of this function from the perspective of reverse thinking:
1: Add a hidden domain data for each record on the data page (selectlist page), and read the values in the hidden domain after the selection.
Example:

 

Code

< Input Type = "Checkbox" Name = "Key" ID = "<C: Out value =" $ {VO. checkmissionid }" /> "Value =" < C: Out Value = "$ {VO. checkmissionid }"   /> "Onclick =" setcheckvalue (' < C: Out Value = "$ {VO. checkmissionid }"   /> ',' < C: Out Value = "$ {VO. checkmissionid }"   /> ') ">
< Input Type = "Hidden" ID = "TD _ <C: Out value =" $ {VO. checkmissionid }" /> "Value =" < C: Out Value = "$ {VO. checkmissionid }" /> ">

 

2: On the data page (selectlist page), add the "obtain selected data" method.

 

Code

Function Getresultinfo (){
VaR Flag = False ;
VaR Values = "" ;
VaR Results = "" ;
VaR Name = ' TD _ ' ;
VaR Checkboxs = Document. getelementsbyname ( " Key " );
For ( VaR I = 0 ; I < Checkboxs. length; I ++ ){
If (Checkboxs [I]. Checked ){
Flag = True ;
Name = Name + Checkboxs [I]. value;
Name = Jtrim (name );
Values = Document. getelementbyid (name). value;
If (I > 0 )
{
Results = Results + ' , ' + Values;
} Else {Results = Values ;}

Name = " TD _ " ;
}
}
If (FLAG)
Return Results;
Else
Return   False ;
}

 

 

3: Add a call to obtain data on the list page and return the method on the call page:

 

Function Addselectedmission ()
{
VaR Results = Result. Window. getresultinfo ();
If (Results ){
Parent. Window. returnvalue = Results;
Parent. Window. Close ();
}
Else Alert ( ' Select a task! ' );
}

 

Explanation: The result object here is the selectlist page. Result. Window. getresultinfo (); is the method used to obtain data on the selectlist page.
The selectlist is embedded into the list page by frame. ItsCodeAs follows:

 

Code

< Tr >
< TD >   <! -- Ui structure begin "Information List rolling area" -->
< Div Class = "Contentdiv" >
<! -- Ui structure begin "Information List table" -->
< IFRAME Name = "Result" ID = "Result" Scrolling = "Yes" Width = "100%" Height = "100%" SRC = '/Techtask/missionInfo-result.do? Method = missioninfoselectlist & VO. worktype = <Bean: Write Name = "Missioninfoform" Property = "VO. worktype" /> 'Frameborder = 0> </ IFRAME >
<! -- Ui structure end "Information List table" -->
</ Div >
<! -- Ui structure end "Information List rolling area" -->   </ TD >
</ Tr >

 

4: Add a button on the list page to trigger the addselectedmission () method.

 

< TD Class = "Btnmain" Onclick = "Addselectedmission ()" > Add selected enterprise </ TD >

 

5: Add a method on the called page to call this list page. And process the returned results.

 

Code

Function Selectmission (){
VaR URL, OPS;
URL =   " /Techtask/missionInfo-result.do? Method = missioninfolist & selecttype = 1 " ;
Ops =   " Dialogheight: 600px; dialogwidth: 800px; center: Yes; resizable: Yes; Status: yes; " ;
VaR A = Window. showmodaldialog (URL, "" , OPS );
Document. getelementbyid ( " VO. checkmissionids " ). Value = A; // Process the returned results.
}

6: Add a button on the page to trigger this event:

 

< TD Class = "Btnmain" Onclick = "Selectmission ()"   > Select administrative task </ TD >
