我不想将模态对话框添加为有关如何使用网站的信息框。我已经完成代码，它可以工作，但我的问题是，我的浏览器中有多个选项卡，而我的模式对话框位于默认选项卡中。当我更改选项卡并再次返回默认选项卡时，模式对话框再次显示。我只想在打开网站时显示一次模态对话框。

$(document).ready(function () {
$('#memberModal').modal('show');

最佳答案
问题终于解决了。
$(document).ready(function() {
var yetVisited =sessionStorage['visited'];
if (!yetVisited) {
$("#Modal").modal("show").on("shown", function () {
window.setTimeout(function () {
$("#Modal").modal("hide");
}, 20000);
});
// open popup
sessionStorage['visited'] ="yes";
}
});
感谢 Patrick 和 ProEvilz。
