Here Mudassar Ahmed Khan has explained how to pass value from child popup window to parent page window using JavaScript.

The child popup window must be opened using JavaScript window.open function. And in such case we can access the parent page controls using JavaScript window.opener instance.

In this article I will explain how to pass value from child popup window to parent page window using JavaScript.

The child popup window must be opened using JavaScript 

window.open function. And in such case we can access the parent page controls using JavaScript 

window.opener instance.

 

Parent Page

Inside the Parent Page I have placed a TextBox which is read-only and a button to open the child popup window using the 

SelectNameJavaScript function.

      
           
        
                 
            Name:         
                 
                    
                 
                    
            
       
      

Popup Child Window Page

The Popup Child Window Page has a DropDownList to choose the name of the person and a button which when clicked calls the 

SetNameJavaScript function.

This function uses the reference of 

window.opener property and finds the 

Parent Page txtName TextBox using 

document.getElementById method of JavaScript and sets the value selected through the DropDownList to it.

In similar way you can access other controls too of the Parent Page from the Child Popup Window Page
