public JavaScriptObject inject()
public ScriptInjector.FromUrl setCallback(Callback<java.lang.Void,java.lang.Exception> callback)
Warning: This class does not control whether or not a URL has already been injected into the document. The client of this class has the responsibility of keeping score of the injected JavaScript files.
Known bugs: This class uses the script tag's onerror()
callback to attempt to invoke onFailure() if the
browser detects a load failure. This is not reliable on all browsers
(Doesn't work on IE or Safari 3 or less).
On Safari version 3 and prior, the onSuccess() callback may be invoked even when the load of a page fails.
To support failure notification on IE and older browsers, you should check some side effect of the script (such as a defined function) to see if loading the script worked and include timeout logic.
callback - callback that gets invoked asynchronously.public ScriptInjector.FromUrl setRemoveTag(boolean removeTag)
removeTag - If true, remove the tag after the script finishes
loading. This shrinks the DOM, possibly at the expense of
readability if you are debugging javaScript.
Default value is false, but this may change in a future
release.public ScriptInjector.FromUrl setWindow(JavaScriptObject window)
builder.setWindow(ScriptInjector.TOP_WINDOW);
window - Specifies which window to install in.
