问题在标题中描述。我有一个 Bootstrap 4 模式和一个带按钮的输入字段的弹出窗口。在 IE 11 中一切正常，但在 Firefox 中输入失去焦点。
弹出窗口：
$('[data-toggle="popover"]').popover({
container: "body",
sanitize: false,
content: function () {
return $("#choose-user-popover-content").html();
}
}).on('shown.bs.popover', function () {
$('#ExecutorSNPSearchStr').focus();
});
弹出框 html：
<div id="choose-user-popover-content" style="display: none;">
<div class="row">
<div class="col">
<div class="input-group">
<input type="text" class="form-control" id="ExecutorSNPSearchStr" aria-describedby="ExecutorSNPSearchStrAddon"/>
<div class="input-group-append" id="ExecutorSNPSearchStrAddon">
<button class="btn btn-sm btn-outline-info w-3" type="button">
<i class="fas fa-search"></i>
</button>
<button class="btn btn-sm btn-outline-danger w-3" type="button">
<i class="fas fa-trash-alt"></i>
</button>
</div>
</div>
</div>
</div>

谁能告诉这是什么原因，以及如何解决这个问题？
UPD： 我在一个单独的 html 文件中重新创建了这种情况。
$(function () {
$('[data-toggle="popover"]').popover({
sanitize: false,
content: function () {
return $("#PopoverContent").html();
}
});
}).on('shown.bs.popover', function () {
$('#ExecutorSNPSearchStr').focus();
});

有一个简单的错误，你有
tabindex="-1"在你的模式中，所以你的输入焦点被它删除了。对于引导程序 4
模式 + 输入弹出窗口
