机器人的WebView跳过的JavaScript即使setJavascriptEnabled（真）和WebChromeClient [英] Android webview SKIPS javascript even with setJavascriptEnabled(true) and WebChromeClient
问题描述
（使用三星Galaxy Tab和Android 3.0，这是为了工作，每一个3.0+平板电脑，就像它在他们的浏览器，只是没有web视图）
(using Samsung Galaxy Tab and Android 3.0, this is intended to work on every 3.0+ tablet, like it does in their browsers, just not webview)
我有一个CSS和jQuery加载罚款，浏览器，浏览器的Android和iOS设备的网页，但是Android的WebView拒绝一贯加载它。
I have a page with CSS and jQuery that loads fine in browsers, android browsers and iOS devices, but android webview refuses to load it consistently.
我已经缩小的问题它只是跳过的JavaScript负载（通过复制一些的WebView的JavaScript应用程序演示该问题）。这是为什么？
I've narrowed down the problem to it simply skipping javascript on load (by replicating the problem with some webview javascript demo apps). Why is this?
下面是完整的HTML测试code

HERE IS THE COMPLETE TEST HTML CODE

和这里是我把它叫做：
myWebview.loadUrl("file:///android_asset/myPage.html");
myWebview.getSettings().setJavaScriptEnabled(true);
myWebview.setWebChromeClient(new WebChromeClient());
这三个调用的顺序不会影响结果。
The ordering of these three calls doesn't effect the result.
myWebview.getSettings().setJavaScriptEnabled(true);
myWebview.setWebChromeClient(new WebChromeClient());
myWebview.loadUrl("file:///android_asset/myPage.html");
有一件事我注意到的是，如果你给它时间（通过暂停在调试器断点的应用程序），那么的JavaScript会更一致加载。这使我试图使应用程序加载速度慢一些牵强的实验，但这是真的不想要的用户体验。我真的希望的Android的WebView真的不是移动开发的IE6。
One thing I've noticed is that if you give it time (by pausing the app with a breakpoint in the debugger) then the javascript will more consistently load. This led me to some farfetched experiments of trying to make the app load slower, but this is really not the desired user experience. I'm really hoping that Android webview really aren't the IE6 of mobile development.
补充资料：
如果您删除＆LT;脚本＆GT; 标签包含所有的jQuery，那么页面加载所有的CSS格式的快。一旦jQuery是添加，没有加载在所有。
If you remove the <script> tags that contain all of the Jquery, then the page loads quickly with all of the CSS formatting. As soon as the Jquery is added, nothing loads at all.
我还发现了一些遇到相同问题的其他问题，很多置之不理或没有确凿的答案是什么OP是寻找：（
I have also found several other questions that encounter the exact same problem, many go unanswered or have no conclusive answer to what the OP was seeking :(

建议？让我们得到的这条底线！ Android的文件说，web视图有一定的局限性，但我不知道该限制的，因为人们将HTML CSS JS应用服务所有的时间！
suggestions? lets get to the bottom of this! The android documentation says the webview has limitations but I don't know where that limit is, since people make HTML CSS JS apps all the time!
推荐答案
答案是JavaScript需要在HTML页面＆LT内的功能;脚本＆GT; 部分然后需要与被注入
webview.loadUrl（JavaScript的：yourJavascriptFunction（））webview.setWebviewClient后（新WebviewClient（）{公共无效onPageFinishedLoading（）{... // JS注射这里}）;
The answer is that the javascript needs to be in functions within the HTML page <script>sections and then needs to be injected with
webview.loadUrl("javascript:yourJavascriptFunction()") after webview.setWebviewClient(new WebviewClient(){ public void onPageFinishedLoading(){ ...//js injections here });
