GWT including external javascript file from module's manifest
提问by Giorgio
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)
所以我阅读了关于在模块清单 yourApplication.gwt.xml (http://code.google.com/webtoolkit/doc/latest/DevGuideOrganizingProjects.html) 中直接包含外部 Javascript 文件的文档
I have this javascript file called iscroll.js and stored in the war/ folder of the GWT project.
我有一个名为 iscroll.js 的 javascript 文件并存储在 GWT 项目的 war/ 文件夹中。
I added the line to the module's manifest of my GWT application:
我将这一行添加到我的 GWT 应用程序的模块清单中：
<script src="iscroll.js"/>
Then from the onModuleLoad()method I call this native JSNI method:
然后从onModuleLoad()我调用这个原生 JSNI 方法的方法：
private native void initJavascript() /*-{
$wnd.myScroll = new iScroll('jokeWrapperLabel');
}-*/;
Then when I run the code in the browser I keep getting "iScroll is undefined".
然后当我在浏览器中运行代码时，我不断收到“iScroll is undefined”。
Any idea what am I doing wrong?
知道我做错了什么吗？
This is the output of the "iScroll is undefined error"
这是“iScroll is undefined error”的输出

You need to place the JavaScript file in a public folder, see this stackoverflow answer on how that works: gwt and javascript filesand the call to iScroll(..must be $wnd.iScroll(...
您需要将 JavaScript 文件放在公共文件夹中，请参阅有关其工作原理的 stackoverflow 答案：gwt 和 javascript 文件以及对iScroll(..must的调用$wnd.iScroll(..。
