我终于弄明白了。
我尝试了 Javascirpt/jquery,但他们无法删除 tabindexes,因为页面尚未完全呈现 - 我的面板以编程方式放置在window.load
. 我所做的是利用RootPanel.class
gwt (已经在使用,但我不知道)。
任务:要摆脱所有带有 -1 值的 tabindex,为所有脚本标签添加 type="tex/javascript",为样式标签添加 type="text/css",并为所有 img 标签添加一个 alt。这些都是为了 html 验证。
我不确定这是不是最好的方法,它确实会增加加载速度,但客户坚持要我这样做。所以这里是:
RootPanel mainPanel = RootPanel.get(Test_ROOT_PANEL_ID);
Widget widget = (Widget) getEntryView();
mainPanel.add((widget));
// Enable the view disable the loading view. There should always be
// the loading panel to disable.
Element mainPanelelement = DOM.getElementById(Test_ROOT_PANEL_ID);
Element loadingMessage = DOM.getElementById(LOADING_MESSAGE);
Element parent = loadingMessage.getParentElement();
if(parent!=null)
{
//i had to use prev sibling because it is the only way that I know of to access the body //tag that contains the scripts that are being generated by GWT ex.bigdecimal.js
Element body = parent.getPreviousSibling().getParentElement();
if(body!=null)
{
NodeList<Element> elms = body.getElementsByTagName("*");
if(elms.getLength()>0)
{
Element element=null;
for(int i=0; i<=elms.getLength(); i++)
{
if(elms.getItem(i)!=null)
{
element = elms.getItem(i);
if(element.getTagName().compareToIgnoreCase("script")==0)
element.setAttribute("type", "text/javascript");
else if(element.getTagName().compareToIgnoreCase("style")==0)
element.setAttribute("type", "text/css");
else if(element.getTagName().compareToIgnoreCase("img")==0)
{
if(element.getAttribute("alt")=="")
element.setAttribute("alt", element.getAttribute("title")!=" " ? element.getTitle() : " " );
}
else
{
if(element.getTabIndex()<=0)
element.removeAttribute("tabindex");
}
}
}
}
}
}
DOM.setStyleAttribute((com.google.gwt.user.client.Element) loadingMessage, "display", "none");
DOM.setStyleAttribute((com.google.gwt.user.client.Element) mainPanelelement, "display", "inline");
// Change cursor back to default.
RootPanel.getBodyElement().getStyle().setProperty("cursor", "default");
}
