google-web-toolkit在圖像中添加alt屬性

嗨，我有一個圖像，它有箭頭。我想添加「alt」屬性。google-web-toolkit在圖像中添加alt屬性

這裏是我的類：

public interface DisclosurePanelArrows extends ClientBundle 
{ 

    public static final DisclosurePanelArrows INSTANCE = GWT.create(DisclosurePanelArrows.class); 

    @Source("disclosurePanelClosed.png") 
    ImageResource disclosurePanelClosed(); 


    @Source("disclosurePanelOpen.png") 
    ImageResource disclosurePanelOpen(); 

}

我把它用在這裏：（不工作）

closedImage = new ICMImage(DisclosurePanelArrows.INSTANCE.disclosurePanelClosed()); 
     openImage = new ICMImage(DisclosurePanelArrows.INSTANCE.disclosurePanelOpen()); 
closedImage.getElement().setAttribute("alt", "close test alt"); 
     openImage.getElement().setAttribute("alt", "open test alt");

我注意到，HTML標籤被編程創建和產生它的.gwtml文件。

唯一的js我發現鏈接到它是這是在WAR文件夾，所以我不知道。

function com_irondata_icmcase_ICMCase(){var O='',vb='" for "gwt:onLoadErrorFn"',tb='" for "gwt:onPropertyErrorFn"',hb='"><\/script>',Y='#',cc='../css/ICMCase.css',dc='../css/dummy.css',bc='../css/theme.css',Wb='.cache.html',$='/',Rb='3A2B8EBB69B48C7A8A7573A74E0C6812',Sb='59203CCA1EBBD79FD6BB80354E15F64D',Vb=':',nb='::',kc='<script defer="defer">com_irondata_icmcase_ICMCase.onInjectionDone(\'com.irondata.icmcase.ICMCase\')<\/script>',gb='<script id="',gc='<script language="javascript" src="',qb='=',Z='?',Eb='ActiveXObject',sb='Bad handler "',Tb='C3CB1347D72F2C0FB0DF18AB080081C2',Fb='ChromeTab.ChromeFrame',Ub='DDDD212960179CCBED9A98B8863C29E1',ec='DOMContentLoaded',ib='SCRIPT',fb='__gwt_marker_com.irondata.icmcase.ICMCase',jb='base',bb='baseUrl',S='begin',R='bootstrap',Db='chromeframe',ab='clear.cache.gif',P='com.irondata.icmcase.ICMCase',db='com.irondata.icmcase.ICMCase.nocache.js',mb='com.irondata.icmcase.ICMCase::',pb='content',X='end',Lb='gecko',Mb='gecko1_8',T='gwt.codesvr=',U='gwt.hosted=',V='gwt.hybrid',Xb='gwt/chrome/chrome.css',ub='gwt:onLoadErrorFn',rb='gwt:onPropertyErrorFn',ob='gwt:property',ac='head',Pb='hosted.html?com_irondata_icmcase_ICMCase',_b='href',Kb='ie6',Jb='ie8',Ib='ie9',wb='iframe',_='img',xb="javascript:''",fc='js/amathcontext.js',hc='js/amathcontext.js"><\/script>',ic='js/bigdecimal.js',jc='js/bigdecimal.js"><\/script>',Yb='link',Ob='loadExternalRefs',kb='meta',zb='moduleRequested',W='moduleStartup',Hb='msie',lb='name',Bb='opera',yb='position:absolute;width:0;height:0;border:none;alt=""',Zb='rel',Gb='safari',cb='script',Qb='selectingPermutation',Q='startup',$b='stylesheet',eb='undefined',Nb='unknown',Ab='user.agent',Cb='webkit';var l=window,m=document,n=l.__gwtStatsEvent?function(a){return l.__gwtStatsEvent(a)}:null,o=l.__gwtStatsSessionId?l.__gwtStatsSessionId:null,p,q,r,s=O,t={},u=[],v=[],w=[],x=0,y,z;n&&n({moduleName:P,sessionId:o,subSystem:Q,evtGroup:R,millis:(new Date).getTime(),type:S});if(!l.__gwt_stylesLoaded){l.__gwt_stylesLoaded={}}if(!l.__gwt_scriptsLoaded){l.__gwt_scriptsLoaded={}}function A(){var b=false;try{var c=l.location.search;return (c.indexOf(T)!=-1||(c.indexOf(U)!=-1||l.external&&l.external.gwtOnLoad))&&c.indexOf(V)==-1}catch(a){}A=function(){return b};return b}

我也試過這個solution但投入差異標籤

任何建議中高音？謝謝。

我找到了。經過8個多小時的苦苦掙扎之後。這是答案。

protected DisclosurePanel   disclosurePanel; 

    if(disclosurePanel.getElement().hasChildNodes()) 
     { 
      NodeList<com.google.gwt.dom.client.Element> imgs = disclosurePanel.getElement().getElementsByTagName("img"); 
      com.google.gwt.dom.client.Element elem = imgs.getItem(0); 
      elem.setAttribute("alt", " "); 
     }

假設ICMImage是一種com.google.gwt.user.client.ui.Image，然後怎麼樣setAltText？

否則，請顯示ICMImage的代碼，因爲您沒有顯示如何您使用的是ImageResource。
