I have an original html like below:
-- <html>
<head/>
<frameset>
<frame>
<html>
<head>
</head>
<body>
</body>
</frame>
<frame>
<html>
<head>
</head>
<body>
</body>
</frame>
<frame>
<html>
<head>
</head>
<body>
</body>
</frame>
</frameset>
</html>
I must use GWT for this original html. I can use GWT.create() and CssResource.ensureInjected() to inject css into top <head>. Because the injected css is not available for frame, I have to inject these css into frame. I don't know why the following code doesn't work:
ClientBundle globalClientBundle = GWT.create(GlobalClientBundle.class);
globalClientBundle.css().ensureInjected();
NodeList<Element> frameNodeList = document.getElementsByTagName("frame");
int length = frameNodeList.getLength();
logger.info("frame size=" + length);
for (int i=0; i<length; i++) {
FrameElement frameElement = (FrameElement)frameNodeList.getItem(i);
logger.info("Frame(id=" + frameElement.getId() + ", name=" + frameElement.getName() + ")");
Document ownerDocument = frameElement.getOwnerDocument();
HeadElement head = ownerDocument.getHead();
if (head != null) {
StyleElement styleElement = ownerDocument.createStyleElement();
HeadElement.as(head).appendChild(styleElement);
String cssText = globalClientBundle.css().getText();
styleElement.setInnerHTML(cssText);
logger.info("Inject css into frame");
}
}
The above code is executing well. But I cannot see any <style> in html code.
Thanks,
David
