我有一些 JQuery，它使用 .trigger 事件来打开/关闭引导折叠容器，但在容器打开后立即滚动到元素时遇到问题。
容器打开后，我需要滚动到或聚焦当前的 "input[required]" 容器打开后。但我并没有这样做的乐趣。
下面是我在做什么的一个例子。
$(document).on("click", ".savechanges", function() {
$("input[required]").on("invalid", function(event) {
var collaspe = $(this).closest('.collapse').hasClass("in");
if (!collaspe) {
$(this).closest('.panel').find('img').trigger("click");
$(this).focus();
} else if (collaspe) {
$("input[required]").off();
} else {
console.log("Do Nothing");
return false;
}
});
});.container {
width: 75%;
}
.head {
background: #D9DBDE;
}
.panel-heading {
background-color: #D9DBDE;
padding: 20px;
margin-bottom: 10px;
border-radius: 0;
}
.panel-title {
font-size: 21px;
display: block;
width: 100%;
color: #4F5858;
line-height: 1.3;
font-weight: normal;
}
.panel-icon {
width: 30px;
padding: 5px;

有人知道如何完成这个或有什么建议吗？
最佳答案
你可以使用 scrollIntoView() DOM API 方法并从相关的引导事件中调用它:
$('#accordion').on('shown.bs.collapse', function (e) {
$('input:focus').prev()[0].scrollIntoView()
});

关于javascript - 在 .trigger(click) 事件后聚焦或滚动到输入元素，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39727451/
