GWT包括来自模块清单的外部javascript文件

Question

So I read the documentation about including an external Javascript file directly in the module manifest yourApplication.gwt.xml (http://code.google.com/webtoolkit/doc/latest/DevGuideOrganizingProjects.html)

I have this javascript file called iscroll.js and stored in the war/ folder of the GWT project.

I added the line to the module's manifest of my GWT application:

<script src="iscroll.js"/>

Then from the onModuleLoad() method I call this native JSNI method:

private native void initJavascript() /*-{
  $wnd.myScroll = new iScroll('jokeWrapperLabel');
}-*/;

Then when I run the code in the browser I keep getting "iScroll is undefined".

Any idea what am I doing wrong?

This is the output of the "iScroll is undefined error"

您需要将JavaScript文件放在公共文件夹中，请参阅此stackoverflow答案，了解其工作原理： gwt和javascript文件以及对iScroll(..的调用iScroll(..必须是$wnd.iScroll(..
