After loading iframe, perform contentDocument operations.

 

How can I operate the elements in contentDocument after loading the corresponding aspx in iFrame?

Ideas:

First, determine whether the readyState of iframe is in the completed state. If yes, perform the corresponding operation. Otherwise, the recurrence will continue after a certain interval of time using the method itself.

 

RestoreViewState ()

{

If (iframe. readyState = "complete ")
{

Handling iframe. contentDocument
}

Else

{

SetTimeOut ('restoreviewstate () ', 100)

}

}

 

 

The Code is as follows:

 

Function restoreViewState (id)

{

Var myArray = document. getElementById (id). value;

Frame = document. getElementById ("iframe ");

If (frame. readyState = "complete ")

{

// Alert (myArray );

Var controls = myArray. split ("&");

For (I = 0; I <controls. length; I ++)

{

Control = controls [I];

Var controlInfo = control. split (",");

If (frame. contentDocument. getElementById (controlInfo [0])! = Undefined)

{

Frame. contentDocument. getElementById (controlInfo [0]). value = controlInfo [1];

}

}

}

Else

{

SetTimeout ("restoreViewState ('" + id + "')", 10 );

}

}
