我正在尝试在WebView中运行网页。我正在加载的页面中有javascript,它可以在我的桌面浏览器上运行,但在android模拟器中不起作用。在模拟器中,我收到此错误:
09-13 18:29:18.496 32087-32087 / com.gamesmart.gamesmart I / chromium:[INFO:CONSOLE(91)]“未捕获的TypeError:无法读取未定义的属性'getAttribute'”,来源:{{ 3}}(91)
我在页面上运行的JavaScript如下所示:
<script>
window.onload = function(){
var items = document.querySelectorAll('a.item');
for(var i = 0; i < items.length; i++){
var item = items[i];
item.addEventListener('click', function(event){
event.preventDefault();
window.JSInterface.playGame(items[i].getAttribute('href'));
});
}
}
</script>
然后我正在运行的Java看起来像这样:
public class MainActivity extends AppCompatActivity {
private WebView webView;
private WebViewClient client;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
JavaScriptInterface jsInterface = new JavaScriptInterface(this);
// Setup the WebView
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
webView.setWebChromeClient(new WebChromeClient());
webView.setInitialScale(1);
webView.getSettings().setAllowFileAccess(true);
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setDomStorageEnabled(true);
webView.addJavascriptInterface(jsInterface, "JSInterface");
// Load a default URL into the webview
webView.loadUrl("http://dev.gamesmart.com/mobile");
}
}
我错过了什么吗?
答案 0 :(得分:0)
尝试替换此
window.JSInterface.playGame(items[i].getAttribute('href'));
用这个
window.JSInterface.playGame(item.getAttribute('href'));
