Pass value from child to parent window
Java example program to pass value from child window to parent window
We can pass values from a child window in Html to the parent window. This can be done very easily. Here is the program that takes the value from the child window and then pass it to the parent window. To explain this example we have made two HTML files as follows:
- Parent.html : It calls the child window for taking the input value that will be further passed to the parent window and parent window also displays the passed value.
- child.html : This the child widow which will be open when we open it from the parent window and will take the value to pass it on to the parent window.
Here is the code for both of the HTML files as follows:
Parent.html
| <html> <head> <title> Parent Window </title> </head> <body> <form method=post name="form"> <table border=0 cellpadding=0 cellspacing=0 width=550> <tr> <td> <font size=2>Show Text</font> <input type="text" name='parent_name' size='8'> <a href="javascript:void(0);" name="newWindow" title="Child Window" onClick="window.open('child.html','newWindow','width=550, height=170,left=150,top=200,toolbar=no,resizable=false')"> Open child window </a> </td> </tr> </table> </form> </body> </html> |
child.html
| <html> <head> <script langauge="javascript"> function post_value(){ opener.document.form.parent_name.value = document.frm.child_name.value; self.close(); } </script> <title>Child Window</title> </head> <body> <form name="frm" method=post action=''> <table border=0 cellpadding=0 cellspacing=0 width=250> <tr> <td align="center"> Input Text : <input type="text" name="child_name" size=12> <input type="button" value="Submit" onclick="post_value();"> </td> </tr> </table> </form> |
When we will run the parent file it will look like this:
By clicking on the link "Open Child window" link will open child window as
Here we have to insert or input text which is to be passed to the parent window.
Click on the submit button.
Here is the full code of both files. You can download it.
