安卓的WebView不具有自定义加载JavaScript WebViewClient [英] android: webview not loading javascript with custom WebViewClient

问题描述

我有一个非常基本的的WebView 这工作，直到我尝试添加自定义的 webViewClient ，其中停止处理JavaScript的。难道我做错了什么？有另一种方式来摆脱在WebView中的地址栏和菜单选项的？

 浏览器=（的WebView）findViewById（R.id.webkit）;    WebSettings webSettings = browser.getSettings（）;
    webSettings.setJavaScriptEnabled（真）;    //取消注释此行，都将加载删除地址栏，还不停的JavaScript
    //browser.setWebViewClient(new InternalWebViewClient（））;    //即使在取消这条线将停止加载的JavaScript
    //browser.setWebViewClient(new WebViewClient（））;    browser.setWebChromeClient（新InternalWebChromeClient（））;
    如果（savedInstanceState！= NULL）{
        browser.restoreState（savedInstanceState）;
    }其他{
        browser.loadUrl（HTTP：//site.with.javascript）;
    }
 

解决方案

由于某种原因WebKit的运行JS不同于浏览器 - 我最终得到解决该问题，迫使一些JS与以下行运行该页面有后加载：

  browser.loadUrl（JavaScript的：的document.getElementById（'东西'）do.something（））;
 

I've got a very basic WebView which works until I try to add a custom webViewClient where it stops processing JavaScript. Am I doing something wrong? Is there another way to get rid of the address bar and menu options in the WebView?

    browser = (WebView) findViewById(R.id.webkit);

    WebSettings webSettings = browser.getSettings();
    webSettings.setJavaScriptEnabled(true);

    // uncommenting this line will remove address bar, but also stop JavaScript from loading
    //browser.setWebViewClient(new InternalWebViewClient());

    // even uncommenting this line will stop JavaScript from loading
    //browser.setWebViewClient(new WebViewClient());

    browser.setWebChromeClient(new InternalWebChromeClient());
    if (savedInstanceState != null) {
        browser.restoreState(savedInstanceState);
    } else {
        browser.loadUrl("http://site.with.javascript");
    }

解决方案

For some reason the webkit runs JS differently than the browser - I ended up getting around the issue by forcing some JS to run with the following line after the page had loaded:

browser.loadUrl("javascript:document.getElementById('something').do.something()");
