问题描述

我正在尝试在视图寻呼机中加载网络视图.

I am trying to load webviews in a view pager.

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = null;      
    v = inflater.inflate(R.layout.webview_layout, container, false);
    myWebView = (WebView)v.findViewById(R.id.webview1);
    WebSettings webSettings = myWebView.getSettings();      
    webSettings.setJavaScriptEnabled(true);
    webSettings.setAppCacheEnabled(true);
    webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
    myWebView.loadUrl("file:///android_asset/web/index.html");
    myWebView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageFinished(WebView view, String url) {
            myWebView.loadUrl("javascript:testFunction()");
        }
    }
}

加载页面后，在onPageFinished()中调用了一个javascript函数以正常速度滚动时，网页正在加载并执行 javascript.

After loading the page, a javascript function is called in onPageFinished() While scrolling at normal speed the webpages are loading and the javascript is executed.

但是在高速滚动时出现以下异常.

But while scrolling at high speed the following exception is occured.

> testFunction is not defined:1

testFunction() 是

testFunction() is 

function testFunction(){
    console.log("TestFuntion");     
}

请帮忙...

推荐答案

我已经解决了这个问题

只需设置 webChromeClient 并捕获错误并重新加载页面...

just set webChromeClient and catch the error and reload the page...

    myWebView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            isLoading = true;
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            myWebView.loadUrl("javascript:testFunction()");
        }
    });

    myWebView.setWebChromeClient(new WebChromeClient() {
        @Override
        public boolean onConsoleMessage(ConsoleMessage consoleMessage) {
            MessageLevel level = consoleMessage.messageLevel();
            if(level.ordinal() == 3) { // Error ordinal
                if(loading) {
                    myWebView.stopLoading();
                    myWebView.loadUrl(AppConstants.ARTICLE_PAGE_URL);
                }
            }
        }
        return false;
    }
