我的動態添加的對象不會完全拾取樣式。 我有這些HTML對象:動態添加的對象不會在javascript中拾取樣式
<div id="cssmenu">
<ul id="buttonsDiv">
</ul>
</div>
我加入了幾個li元素:
for (var i = 0; i < numOfDays; i++) {
let j=i;
var newButton = $("<li class='active has-sub'><a href='#'><span> Day " + (i + 1) + "</span></a><ul id=button" + (i + 1) + "></ul></li>");
$("#buttonsDiv").append(newButton);
}
,並在單擊某個對象後,我想插入子菜單項:
function addEvents(attraction)
{
var newButton = $("<li><a href='#'><span>"+ attraction+ "</span></a></li>");
var ulChildren = document.getElementById('buttonsDiv').children;
var childrenLength = ulChildren.length;
for(var i = 0; i < childrenLength; i++){
if(ulChildren[i].children[1].id == day){
$(ulChildren[i].children[1]).append(newButton);
}
}
}
現在,當我「檢查」網絡上的元素時(他們正在添加),插入按預期工作。 但由於某種原因,它沒有得到正確的樣式,當我對對象進行硬編碼時,我得到了期望的效果。 它與DOM沒有識別我的新元素有關嗎?
任何人都可以指向正確的方向嗎?

小提琴會很好。從你所說的聽起來像CSS選擇器是不好的。動態DOM節點沒有理由違反CSS規則。你能創建一個工作片段並與我們分享嗎? – sospedra
也請添加樣式表的代碼。動態添加元素不應該有任何問題。 –
