Sending child window’s value to parent window is one of the very common requirements for web developers. I also used it a lot, so decided to make a post for some of our beginners friends to Javascript. There are many ways you can send values of child window to parent window, however, I have described here two ways to send value from child window to parent.
Either you can send value through an argument to a function or you can directly set parent window’s object value from the client window. How to do it? that I have described below.
Find the below code to send value to parent window through an argument to a function. Write below code in your parent window.
<head>
<script language=”javascript” type=”text/javascript”>
function GetValueFromChild(myVal)
{
document.getElementById(‘mytxt’).value = myVal;
}
</script>
</head>
<body>
<input id=”mytxt” type=”text” />
</body>
Fig. 1
Here in fig 1, “mytxt” is a textbox object whose value will be received from the child window. “myVal” is argument of this function, this function will be called from the child window later.
Find the below code to be written in child window.
<head>
<script language=”javascript” type=”text/javascript”>
function SendValueToParent()
{
var myVal = document.getElementById(‘mytxt’).value;
window.opener.GetValueFromChild(myVal);
window.close();
return false;
}
</script>
</head>
<body>
Type text here and send it to parent window:
<input id=”mytxt” type=”text” />
<input id=”btn1″ type=”button” value=”Send Value to Parent”onclick=”javascript:return SendValueToParent();” />
</body>
Fig. 2
Here in fig 2, we are sending child window’s textbox value to the parent window’s function by calling “GetValueFromChild(myVal)”. “myVal” is the value of the child window’s textbox and will be sent to parent window as an argument by clicking “btn1” button.
You can also set parent window’s object value from the child window. You only need to do is, just write the below code in your child window only and there is no need to write any script in the parent window. Only you need is a textbox or any other object that can display the value of the parent window in browser.
Put the following code in child window to set parent window’s object value:
<head>
<script language=”javascript” type=”text/javascript”>
function SetValueInParent()
{
window.opener.document.form1.mytxt.value = document.getElementById(‘mytxt1′).value;
window.close();
return false;
}
</script>
</head>
<body>
Type text here and set it to parent window :
<input id=”mytxt1″ type=”text” />
<input id=”btn1″ type=”button” value=”Set Value in Parent”onclick=”javascript:return SetValueInParent();” />
</body>
Fig. 3
In fig 3, we have set the value of child window’s textbox object to parent window’s textbox object directly by using it’s ID property. I have called this function by clicking on “btn1” button.
