E / Web控制台（8272）：未捕获的Ref​​erenceError：函数名没有定义：1，同时加载webviews视图中的寻呼机 [英] E/Web Console(8272): Uncaught ReferenceError: functionName is not defined:1 while loading webviews in a View Pager

问题描述

我试图加载webviews在视图中的寻呼机。

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，一个JavaScript函数被调用 onPageFinished（） 而在正常的速度滚动的网页加载并执行JavaScript的。

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.

但在高速滚动时下列异常发生。

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

我对这个修复

刚刚成立webChromeClient和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;
    }
