問題描述圖片描述瀏覽器報錯，（找不到className，是這個意思嗎？），應該怎么解決呢。還有一個問題，傳入的值為元素，元素是個什么定義呢？相關代碼這是前端頁面特性分支集成分支歷史版本這是common.jsfunctionhasClass(elementone,cName){if(!elementone||elementone.className==null){returnfalse;}return!!elementsone.className.match(newRegExp("(\\s|^)"+cName+"(\\s|$)"));}functionaddClass(elementOne,cName){if(!hasClass(elementOne,cName)){elementOne.className+=""+cName;//這里是common.js第96行};}functionremoveClass(elementOne,cName){if(hasClass(elementOne,cName)){elementOne.className=elementOne.className.replace(newRegExp("(\\s|^)"+cName+"(\\s|$)"),"");//replace方法是替換};}這是方法的調用:functiononloadTable(){varBranchTypeID=getCookie("BranchTypeID");varfeatureLi=document.getElementById("featureLi");varintegrationLi=document.getElementById("integrationLi");varpublishedLi=document.getElementById("publishedLi");varFeature=document.getElementById("Feature");varIntegration=document.getElementById("Integration");varPublished=document.getElementById("Published");if(BranchTypeID==1){//為這個類移除屬性addClass(featureLi,"active");removeClass(integrationLi,"active");removeClass(publishedLi,"active");$("#featureA").attr("aria-expanded","true");$("#integrationA").attr("aria-expanded","false");$("#publishedA").attr("aria-expanded","false");addClass(Feature,"active");removeClass(Integration,"active");removeClass(Published,"active");}if(BranchTypeID==2){//為這個類移除屬性removeClass(featureLi,"active");addClass(integrationLi,"active");removeClass(publishedLi,"active");removeClass(Feature,"active");addClass(Integration,"active");removeClass(Published,"active");$("#featureA").attr("aria-expanded","false");$("#integrationA").attr("aria-expanded","true");$("#publishedA").attr("aria-expanded","false");}if(BranchTypeID==3){//為這個類移除屬性removeClass(featureLi,"active");removeClass(integrationLi,"active");addClass(publishedLi,"active");$("#featureA").attr("aria-expanded","false");$("#integrationA").attr("aria-expanded","false");$("#publishedA").attr("aria-expanded","true");removeClass(Feature,"active");removeClass(Integration,"active");addClass(Published,"active");}setInterval("checkPipelineStatus()",10000);}
