使用Javascript不工作在web视图活动 [英] Javascript not working in a WebView Activity
问题描述
我有一个活动,刚一的WebView ,其中包含HTML,CSS和Javascript code。
似乎有与在访问问题 Javascript的以视图的屏幕尺寸。 LogCat中说:
(标签:Web控制台):未捕获的类型错误:不能调用方法'的getWidth'未定义
在文件:///android_asset/Prospekte/grund/html5-player/js/epaper-mobile.js:20
当我考虑了JS文件,有:变种F = this.body.getWidth();
有奇怪的是,有时候code工作。该电子纸显示良好。但大多数时候有这个错误。
的setContentView(R.layout.prospekt_layout);
最后活动活动=这一点;
mWebView =(web视图)findViewById(R.id.prospekt_webview);
mWebView.getSettings()setJavaScriptEnabled(真)。
mWebView.getSettings()setDomStorageEnabled(真)。
mWebView.setWebChromeClient(新WebChromeClient(){
公共无效onProgressChanged(web视图来看,INT进度){
activity.setProgress(进度* 1000);
}
});
mWebView.setWebViewClient(新WebViewClient(){
@覆盖
公共无效onReceivedError(web视图来看,INT错误code,字符串描述,字符串failingUrl)
{
//处理错误
}
@覆盖
公共布尔shouldOverrideUrlLoading(web视图查看,字符串URL)
{
view.loadUrl(URL);
返回true;
}
});
mWebView.loadUrl(文件:///android_asset/Prospekte/modKachel/mobile.html);
的布局是:
< XML版本=1.0编码=UTF-8&GT?;
<的LinearLayout
的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:layout_height =match_parent
机器人:layout_width =match_parent
>
<的WebView
机器人:ID =@ + ID / prospekt_webview
机器人:layout_width =900px
机器人:layout_height =900px
/>
< / LinearLayout中>
我改变了web视图的大小,因为我认为这可能是solution..but它要么与DP没有工作。
有人有想法?
你的web视图设置此设置以及
WebSettings设置= webView.getSettings();
settings.setDomStorageEnabled(真正的);

更新: 或者加入这可能帮助:
webView.loadDataWithBaseURL(假://fake.com,MyString的,text / html的,UTF-8,NULL);
I have an Activity that has just a WebView, which contains HTML, CSS and Javascript Code.
It seems that there's a problem with the access of Javascript to the screen size of the view. LogCat says:
(Tag: Web Console): Uncaught TypeError: Cannot call method 'getWidth' of undefined
at file:///android_asset/Prospekte/grund/html5-player/js/epaper-mobile.js:20
When I look into the js-file, there is: var f=this.body.getWidth();
There curious thing is that sometimes the code works. The epaper is shown well. But most time there's this error.
setContentView(R.layout.prospekt_layout);
final Activity activity = this;
mWebView = (WebView) findViewById(R.id.prospekt_webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setDomStorageEnabled(true);
mWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
activity.setProgress(progress * 1000);
}
});
mWebView.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
// Handle the error
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
});
mWebView.loadUrl("file:///android_asset/Prospekte/modKachel/mobile.html");
The layout is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent"
>
<WebView
android:id="@+id/prospekt_webview"
android:layout_width="900px"
android:layout_height="900px"
/>
</LinearLayout>
I changed the size of the webView cause I thought that this could be the solution..but it's no working with dp either.
Someone has in idea?
Set this setting as well for your webView:
WebSettings settings = webView.getSettings();
settings.setDomStorageEnabled(true);

Update: or adding this might help:
webView.loadDataWithBaseURL("fake://fake.com", myString, "text/html", "UTF-8", null);
