webView.setWebChromeClient(new WebChromeClient() {
//获取网页的标题
@Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
setTitle(title);
}


//重写alert弹框
@Override
public boolean onJsAlert(WebView view, String url, final String message, JsResult result) {
WjLog.d("main", "onJsAlert:" + message);
runOnUiThread(new Runnable() {
    @Override
    public void run() {
        new AlertDialog.Builder(WebViewActivity.this)
                .setTitle("提示")
                .setMessage(message)
                .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        //webView.reload();//重写刷新页面
            }
        }).show();
    }
});
result.confirm();//这里必须调用，否则页面会阻塞造成假死
return true;
}
});
