android - 如何从 webview 中删除类

Question

我正在尝试删除这个 div:

<div data-role="navbar" data-iconpos="bottom" class="ui-navbar" role="navigation">
    <ul class="ui-grid-b">
        <li class="ui-block-a">
            <a href="http://www.siverekhaber.net/mobil/galeriler.html" data-icon="camera"
               class="ui-link ui-btn ui-icon-camera ui-btn-icon-bottom">Galeri</a>
        </li>
        <li class="ui-block-b">
            <a href="http://www.siverekhaber.net/mobil/videolar.html" data-icon="video"
               class="ui-link ui-btn ui-icon-video ui-btn-icon-bottom">Video</a>
        </li>
        <li class="ui-block-c">
            <a href="http://www.siverekhaber.net/mobil/yazarlar.html" data-icon="edit"
               class="ui-link ui-btn ui-icon-edit ui-btn-icon-bottom">Yazarlar</a>
        </li>
    </ul>
</div>

我尝试覆盖 onPageFinished 方法:

@Override
    public void onPageFinished(WebView view, String url) {
        view.setVisibility(View.VISIBLE);
        final Animation fade = new AlphaAnimation(0.0f, 1.0f);
        fade.setDuration(200);
        view.startAnimation(fade);
        view.setVisibility(View.VISIBLE);
        mRefreshPbar.setVisibility(View.INVISIBLE);
        mRefreshBtn.setVisibility(View.VISIBLE);
        updateActionView();
        mWebview.loadUrl("javascript:(function() { " +
            "if (typeof(document.getElementsByClassName('ui-footer')[0]) != 'undefined' && document.getElementsByClassName('ui-footer')[0] != null){"+
            "document.getElementsByClassName('ui-footer')[0].style.display = 'none';"+
            "})()");
    }

但它不起作用。有什么问题？

您需要调用void 0 来阻止浏览器重定向到纯文本文件。

mWebview.loadUrl("javascript:if (typeof(document.getElementsByClassName('ui-footer')[0]) != 'undefined' && document.getElementsByClassName('ui-footer')[0] != null){document.getElementsByClassName('ui-footer')[0].style.display = 'none';} void 0");
