  com.google.gwt.core.client.ScriptInjector

public class ScriptInjector
extends java.lang.Object

Dynamically create a script tag and attach it to the DOM. Usage with script as local string:

   String scriptBody = "var foo = ...";
   ScriptInjector.fromString(scriptBody).inject();
 

Usage with script loaded as URL:

   ScriptInjector.fromUrl("http://example.com/foo.js").setCallback(
     new Callback() {
        public void onFailure(Exception reason) {
          Window.alert("Script load failed.");
        }
        public void onSuccess(Void result) {
          Window.alert("Script load success.");
        }
     }).inject();
 

TOP_WINDOW

public static final JavaScriptObject TOP_WINDOW

Returns the top level window object. Use this to inject a script so that global variable references are available under $wnd in JSNI access.

Note that if your GWT app is loaded from a different domain than the top window, you may not be able to add a script element to the top window.

Build an injection call for directly setting the script text in the DOM.

Parameters:

scriptBody - the script text to be injected and immediately executed.

fromUrl

public static ScriptInjector.FromUrl fromUrl(java.lang.String scriptUrl)

Build an injection call for adding a script by URL.

Parameters:

scriptUrl - URL of the JavaScript to be injected.
