[英]jQuery How to add a class to a div if another div has specific class
if any of the webpage elements has is-open class, add open class to another div.如果任何网页元素具有is-open class,请将open class 添加到另一个 div。 doesn't work不起作用
is-open is added to div's each time a modal or tab is opened on the page.每次在页面上打开模式或选项卡时,都会将is-open添加到 div。
<script>
if($(".is-open").length){
$(".blur-screen").addClass("open");
} else {
$(".blur-screen").removeClass("open");
}
</script>
The code in your script runs immediately (before is-open is added to a div, because that only happens if a modal or tab is open, which probably doesn't happen immediately when page is loaded).脚本中的代码会立即运行(在将 is-open 添加到 div 之前,因为只有在模式或选项卡打开时才会发生这种情况,这可能不会在加载页面时立即发生)。
what you need to do is to call a function that will check it every time a modal/tab is opened您需要做的是调用 function 每次打开模式/选项卡时都会检查它
function checkIsOpen() {
if($(".is-open").length){
$(".blur-screen").addClass("open");
} else {
$(".blur-screen").removeClass("open");
}
}
when modal/tab opens:当模态/标签打开时:
checkIsOpen();
Try this,试试这个,
if($("div").hasClass('is-open')){
$(".blur-screen").addClass("open");
} else {
$(".blur-screen").removeClass("open");
}
