Hi all,
i try to set up an iframe in a jsp(portal.jsp) and wrap a
lzx(webtop.lzx) in it. However, in webtop.lzx, when i try to call the
outer user-defined js funtion through callJS, it failed to execute my
function.
webtop.lzx:
<canvas>
<attribute name="webtopView"/>
<handler name="onwebtopView">
LzBrowser.callJS("webtopChangedView", null, "summary/full");
</handler>
<view height="100" bgcolor="blue" name="webtop">
<button name="mybutton" text="button">
<handler name="onclick">
Lz.setCanvasAttribute("webtopView", "summary");
</handler>
</button>
</view>
</canvas>
portal.jsp:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd
">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf8" />
<title>Portal</title> <script language="javascript"
type="text/javascript"> function webtopChangedView(view) {
if (view == "summary") {//change widget to summary size
alert("Summary:" + view);
}else { //change widget to standard size
alert("standard:" + view);
}
}
</script>
</head>
<body>
Portal view
<iframe src="webtop.lzx" width="100%" height="700px"> </iframe>
</body> </html>
but if i changed LzBrowser.callJS("webtopChangedView", null,
"summary/full") to call a primitive window function like
LzBrowser.callJS("window.open", null, "summary/full"), it did execute,
so my question is how to invoke outer use-defined js function in an
iframe wrapped lzx. I couldn't get help from both reference guide or
openlaszlo forum. Thanks for your time.
Regards.
