我正在尝试使用以下代码在 android webview 中显示包含 HTML 和 javascript 的页面。但这似乎不起作用。任何人都可以帮助我。
公共(public)类 MainActivity 扩展了 ActionBarActivity {
WebView browser;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.activity_main);
browser = (WebView) findViewById(R.id.webView);
browser.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
browser.setWebViewClient(new Callback());
browser.getSettings().setJavaScriptEnabled(true);
loadTime();
}
void loadTime() {
String page = "<html>"
+"<head>"
+"<title>chat window</title>"
+"<script type=\"text/javascript\">"
+ "var bccbId = Math.random(); document.write(unescape('%3Cdiv id=' + bccbId + '%3E%3C/div%3E'));"
+" window._bcvma = window._bcvma || [];"
+" _bcvma.push([\"setAccountID\", \"423771628801258096\"]);"
+" _bcvma.push([\"setParameter\", \"WindowParameters\", \"vr=&vi=&ve=" + gblQnbVars["gUserEmail"] + "&vp=" + gblQnbVars["gMobileNum"] + "&vn= "+ gblQnbVars["gCustomerFirstName"]+ "&lc=\"]);"
+"var bcLoad = function(){"
+ " if(window.bcLoaded) return; window.bcLoaded = true;"
+" var vms = document.createElement(\"script\");"
+"vms.type = \"text/javascript\";"
+" vms.async = true;"
+" vms.src = ('https:'==document.location.protocol?'https://':'http://') + \"vmss.boldchat.com/aid/423771628801258096/bc.vms4/vms.js\";"
+"var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(vms, s);"
+"};"
+"if(window.pageViewer && pageViewer.load) pageViewer.load();"
+" else if(document.readyState==\"complete\") bcLoad();"
+" else if(window.addEventListener) window.addEventListener('load', bcLoad, false);"
+" else window.attachEvent('onload', bcLoad);"
+ "function FireBoldChat() {"
+" try {"
+ " _bcvmw.chatWindow({"
+ "type: \"chat\","
+ "rdid: \"\","
+ "cwdid:\"1504531236710990857\","
+ "ve:\"<%=visitor email%>\","
+ "vp:\"<%=visitor phone%>\","
+ "vn:\"<%=visitor name%>\","
+ "embed: true"
+ "});"
+" } catch (e) {"
+"setTimeout(FireBoldChat, 500)"
+" }"
+" };"
+" </script>"
+"</head>"
+"<body onload=\"FireBoldChat();\">"
+"</body>"
+"</html>";
System.out.println(page);
browser.loadDataWithBaseURL("x-data://base", page,
"text/html", "UTF-8",
null);
}
private class Callback extends WebViewClient {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
loadTime();
return(true);
}
}
每当我在默认浏览器中加载我的这个网页时，它都能完美运行。我哪里做错了。
最佳答案
loadData() 的文档说
Note that JavaScript's same origin policy means that script running in a page loaded using this method will be unable to access content loaded using any scheme other than 'data', including 'http(s)'. To avoid this restriction, use loadDataWithBaseURL() with an appropriate base URL.
现在您确实使用了 loadDataWithBaseURL()，但是您的基本 URL 是 x-data://base 但您尝试从 http(s) 加载脚本://vmss.boldchat.com。我认为这可能会导致您的问题。
