如何在gwt Uibinder中使用JavaScript [英] How to use JavaScript with gwt Uibinder
问题描述
我想在我用GWT编写的应用程序中执行JavaScript。
这是以普通HTML工作的代码：
< html>
< head>
< / head>
< body>
< ul>
< li>< / li>
< li>< / li>
< li>< / li>
< li>< / li>
< li>< / li>
< / ul>
< script src =jquery.js>< / script>
< script src =jquery.roundabout.js>< / script>
< script>
$（document）.ready（function（）{
$（'ul'）。roundabout（）;
}）;
< / script>
< / body>
< / html>
（假设 jquery.js 和<$ ）
我有一个 somePresenter code>（with someView.java 和 someView.ui.xml ），我希望上面的代码工作在 someView.ui.xml 。
我复制上面的代码粘贴到XML（除< html> 标签我有< g：HTMLPanel> 标签）
，但JavaScript没有似乎会被执行（我所看到的只是列表，因为它应该在脚本之前）。
如何让它工作？
相关问题：我可以使用GQuery来处理这个
（类似于：GQuery。$（）。getScript（jquery.roundabout.js）来加载外部js脚本）吗？
提前致谢
c>< script> 在UiBinder中，并期望看到它的加载和执行原因与你相同不要在JS中的 innerHTML 中放置< script> > HTMLPanel 和UiBinder将使用 innerHTML 内置）。
如果您需要动态加载脚本，查看 ScriptInjector ：
ScriptInjector.fromUrl（GWT.getModuleBaseURL（）+'jquery.js'）。inject（）;
我想GQuery使用 ScriptInjector 。
I want to execute JavaScript in my application which is written with GWT. This is the code that works in a regular HTML:
<html>
<head>
</head>
<body>
<ul>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
</ul>
<script src="jquery.js"></script>
<script src="jquery.roundabout.js"></script>
<script>
$(document).ready(function() {
$('ul').roundabout();
});
</script>
</body>
</html>
(Assume jquery.js and jquery.roundabout.js are in the same folder.)
I have a somePresenter (with someView.java and someView.ui.xml) and I want the above code to work in the someView.ui.xml.
I copy pasted the above code to the XML (except for <html> tag I have <g:HTMLPanel> tag)
but the JavaScript doesn't seem to be executed (all I see is the list as it should be before the script).
How can I make it work?
Related question: can I some how use GQuery for this (something like: GQuery.$().getScript(jquery.roundabout.js) to load external js script)?
Thanks in advance
You can't put a <script> in UiBinder and expect to see it loaded and executed for the same reasons you cannot put a <script> in a innerHTML in JS with the same expactations (simply because HTMLPanel and UiBinder will use innerHTML under-the-hood).
If you need to load scripts dynamically, have a look at the ScriptInjector:
ScriptInjector.fromUrl(GWT.getModuleBaseURL() + 'jquery.js').inject();
I suppose GQuery uses ScriptInjector or works similarly.
