webview 不显示 javascript windows.open()
我有一个 WebView,其中显示我无法控制的网页内容。内容显示正常,但有生成弹出窗口的链接。执行此操作的 javascript 函数如下所示:
function getEntry(id) {
var win = window.open('', 'Booking',
'resizable=yes,scrollbars=yes,status=no,width=500,height=400');
win.document.location = '/some/url/1-' + id ;
}
我无法轻松更改此设置,如果负责我下载页面的人员更改它,我想我的应用程序会严重失败......
我的 WebView
活动中的设置如下所示:
_webview = new WebView(this);
setContentView(_webview);
final Activity activity = this;
_chromeClient = new MyChromeClient();
_webview.setWebChromeClient(_chromeClient);
//I experimented with changing user agent, in case that would have any effect, it didn't...
_webview.getSettings().setUserAgentString("Mozilla/5.0 (Windows NT 5.1; rv:9.0.1) Gecko/20100101 Firefox/9.0.1");
_webview.setWebViewClient(new MyWebViewClient());
_webview.getSettings().setJavaScriptEnabled(true);
_webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
_webview.getSettings().setSupportZoom(true);
_webview.getSettings().setBuiltInZoomControls(true);
_webview.getSettings().setDomStorageEnabled(true);
//Cache settings...
_webview.getSettings().setAppCacheMaxSize(1024*1024*8);
_webview.getSettings().setAppCachePath("/data/data/com.your.package.appname/cache");
_webview.getSettings().setAllowFileAccess(true);
_webview.getSettings().setAppCacheEnabled(true);
MyWebClient:
private class MyWebViewClient extends WebViewClient {
@Override
public void onLoadResource(WebView view, String url) {
Log.d("MyWebViewClient",url);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
showProgressDiag();
Log.d("MyWebViewClient","shouldOverride... : " + url);
view.loadUrl(url);
return true;
}
@Override
public void onPageFinished(WebView view, String url){
hideProgressDiag();
}
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
if(failingUrl.equals("file:///android_asset/html/error.html")){
hideProgressDiag();
Toast.makeText(_context, "Error! Check internet connection, or try again later...", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(_context, failingUrl, Toast.LENGTH_SHORT).show();
view.loadUrl("file:///android_asset/html/error.html");
}
}
}
MyChromeClient:
private class MyChromeClient extends WebChromeClient{
@Override
public void onProgressChanged(WebView view, int progress) {
Pdiag.setProgress(progress * 100);
}
}
当单击指向 javascript 函数的链接之一时,所发生的情况是 WebView
变为灰色,而不经过shouldOverrideUrlLoading()
。当我按下后退键时,应用程序退出,这意味着 WebView 的导航历史记录中没有放置任何内容。有时什么也没有发生,但随后 shouldOverrideUrlLoading()
do run 并从 Log.d()
我可以看到正确的 URL弹出窗口已提供给 WebView。
问题是,在极少数情况下它显示得很好,但我不知道如何重现它,也不知道它是否真的显示在弹出窗口中。
我迷失了......并且非常沮丧......想看一部糟糕的情景喜剧:(
编辑: 实际上,也许 URL 并不是那么正确......在 Firefox 中,URL 以“X<<<<”结尾但在我的 Log.d() 输出中,它以“X%3C%3C%3C%3C”结尾...我将调查是否可以更改它...
编辑2: 不,什么都没做...该 URL 与 Firefox 中的 URL 相同...
I have a WebView
in which i display web content which i have no control over. The content displays fine, but have links which spawn a popup window. The javascript function that does that looks like this:
function getEntry(id) {
var win = window.open('', 'Booking',
'resizable=yes,scrollbars=yes,status=no,width=500,height=400');
win.document.location = '/some/url/1-' + id ;
}
I can't easily change this, and if the people responsible for the page i download would change it, i guess my app would fail miserably...
My WebView
setup in the activity looks like this:
_webview = new WebView(this);
setContentView(_webview);
final Activity activity = this;
_chromeClient = new MyChromeClient();
_webview.setWebChromeClient(_chromeClient);
//I experimented with changing user agent, in case that would have any effect, it didn't...
_webview.getSettings().setUserAgentString("Mozilla/5.0 (Windows NT 5.1; rv:9.0.1) Gecko/20100101 Firefox/9.0.1");
_webview.setWebViewClient(new MyWebViewClient());
_webview.getSettings().setJavaScriptEnabled(true);
_webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
_webview.getSettings().setSupportZoom(true);
_webview.getSettings().setBuiltInZoomControls(true);
_webview.getSettings().setDomStorageEnabled(true);
//Cache settings...
_webview.getSettings().setAppCacheMaxSize(1024*1024*8);
_webview.getSettings().setAppCachePath("/data/data/com.your.package.appname/cache");
_webview.getSettings().setAllowFileAccess(true);
_webview.getSettings().setAppCacheEnabled(true);
MyWebClient:
private class MyWebViewClient extends WebViewClient {
@Override
public void onLoadResource(WebView view, String url) {
Log.d("MyWebViewClient",url);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
showProgressDiag();
Log.d("MyWebViewClient","shouldOverride... : " + url);
view.loadUrl(url);
return true;
}
@Override
public void onPageFinished(WebView view, String url){
hideProgressDiag();
}
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
if(failingUrl.equals("file:///android_asset/html/error.html")){
hideProgressDiag();
Toast.makeText(_context, "Error! Check internet connection, or try again later...", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(_context, failingUrl, Toast.LENGTH_SHORT).show();
view.loadUrl("file:///android_asset/html/error.html");
}
}
}
MyChromeClient:
private class MyChromeClient extends WebChromeClient{
@Override
public void onProgressChanged(WebView view, int progress) {
Pdiag.setProgress(progress * 100);
}
}
When clicking one of the links that points to the javascript function all that happens is that the WebView
turns grey, without going through shouldOverrideUrlLoading()
. When i hit the back key the app exits, meaning that nothing was placed in the nav history of the WebView
. Sometimes nothing happens, but then the shouldOverrideUrlLoading()
do run and from a Log.d()
i can see that the correct URL for the popup has been given to the WebView.
The thing is, on very rare occasions it shows up fine, but i have no clue how to reproduce it, and wether it actually shows in a popup.
I'm lost... And quite frustrated... Thinking of watching a bad sitcom instead :(
EDIT:
Actually, maybe the URL wasn't all that correct after all... In Firefox the URL ends with "X<<<<" but in my Log.d() output it ends with "X%3C%3C%3C%3C"... I'll investigate if i could change that...
EDIT 2:
Nope, didn't do anything... The URL is identical to the one in Firefox...

首先,您需要在
WebView
上进行以下设置:然后您需要附加一个覆盖
onCreateWindow
的WebChromeClient
。您实现此方法可以创建一个新的 Web 视图,并将其显示在对话框中:不要忘记将新的 Web 视图设置为
resultMsg
,将其发送到其目标并返回 true,如下所示API 文档。First of all, you need to set the following settings on your
WebView
:Then you need to attach a
WebChromeClient
that overridesonCreateWindow
. Your implementation of this method can create a new web view, and display it inside a dialog:Don't forget to set the new web view to the
resultMsg
, send it to its target and return true, as mentioned in the API documentation.请检查添加此 -
Please check with adding this -
