In the IFRAME pop-up window, send data back to the parent page [call the js method of the parent page and simulate the send-back event of the call button]

There is now a parent page. The IFRAME embedded window (page B) appears when you click the button, for example:

The function we want to implement is to send the selected information from the pop-up window B to homepage a and process the information when you click OK.

 

First, define the following function for sending back on page:

<Script Type= "Text/JavaScript">

FunctionRebind (ID ){

_ Dopostback ('Ctl00 $ pagebody $ linkbutton1', ID );//Simulate the send-back event of the call button and input a value. Obtain the Client ID of the button.

Tb_remove ();//How to close the pop-up window

}

</Script>

< ASP : Linkbutton ID= "Linkbutton1" Runat= "Server" Onclick= "Linkbutton#click"> </ASP:Linkbutton>

In the background of page A, click the button to send back the event:

//Bound question name

Protected VoidLinkbutton#click (ObjectSender,EventargsE)

{

IntCdid =Int. Parse (request. Form ["_ Eventargument"]. Tostring ());// QuestionID, which is the parameter of the frontend sending back.

/* Processing Method */

}

 

Event triggered when you click OK on page B:

//OK

Protected VoidButton#click (ObjectSender,EventargsE)

{

StringId = hfepid. value;//Obtain the selectedIDValue

StringSTR ="Window. Parent. rebindpaper ('"+ ID +"');";//Call the parent page binding method

Scriptmanager. Registerstartupscript (This. Page,Type. GetType ("System. String"), STR, STR,True);

}

In addition, you can also use the ajaxpro control to call the server-side functions from the client. For details, see:
