How to pass data from Parent html window to pop-up window

问题

I am trying to pass some data from parent window to pop up window in html.

Below is my code-

<html>
<head>
<script type="text/javascript">
function init()
{
    popupWin = window.open('','popupWin','');
    popupWin.document.writeln('<html><head><title>test</title></head><body><form><input type="text" id="popupTextBox"/></form></body></html>');
    popupWin.document.close();
    popupText = popupWin.document.getElementById("popupTextBox");
    parentText = document.getElementById("parentTextBox");
}
function transferText()
{
    popupText.value = parentText.value
}
</script>
</head>
<body>
<input type="text" id="parentTextBox"/>
<input type="button" onclick="init();"/>
</body>
</html>

But somehow I am not able to pass that textbox data to popup window with the above code. Is there any problem with this?

In general, I am trying to pass some data from parent window to popup window.

回答1:

You forgot to call transferText()
After calling transferText() the text was transferred...

<html>
<head>
<script type="text/javascript">
function init()
{
    popupWin = window.open('','popupWin','');
    popupWin.document.writeln('<html><head><title>test</title></head><body><form><input type="text" id="popupTextBox"/></form></body></html>');
    popupWin.document.close();
    popupText = popupWin.document.getElementById("popupTextBox");
    parentText = document.getElementById("parentTextBox");
    transferText();
}
function transferText()
{
    popupText.value = parentText.value
}
</script>
</head>
<body>
<input type="text" id="parentTextBox"/>
<input type="button" onclick="init();"/>
</body>
</html>
