我一直在寻找一种方法来检查var theBody = document.body;
var element = document.createElement("p");
element.id = "status";
element.style.cssText = "float:right; color:red";
element.textContent = "Waiting...";
theBody.insertBefore(element, theBody.firstChild);
function replyToMessage(aMessageEvent) {
if (aMessageEvent.name === "hey") {
document.getElementById("status").textContent="Message received.";
safari.self.tab.dispatchMessage("gotIt","Message acknowledged.");
}
}
safari.self.addEventListener("message", replyToMessage, false);
是否已被用户或超时人员关闭。我真的听不懂。
这是我到目前为止所得到的,
Snackbar
这是一种解决方法,我一直在寻找准确的监听器。我不需要任何解决方法,例如设置Scaffold.of(context)
.showSnackBar(SnackBar(content: Text("Title")))
.closed
.then((reason) {
// snackbar is now closed
});
的{{1}},然后在持续时间过去之后再听。
答案 0 :(得分:0)
请参阅下面的完整示例
我只是用public class AdresMap : ClassMapping<Adres>
{
public AdresMap()
{
this.Table("Adres"); //Your table name
this.Id(c => c.Id, c =>
{
c.Generator(Generators.Native);
c.Type(NHibernateUtil.Int64);
c.Column("Id");
c.UnsavedValue(0);
});
Set(x => x.Chauffeurs, c =>
{
c.Key(k =>
{
k.Column("Id");
k.ForeignKey("AdresId");
});
c.Inverse(true);
c.Cascade(Cascade.None);
},
r => r.OneToMany(o => { }));
this.Property(x => x.Straat );
// ... other properties
}
}
包装了library(dplyr)
df %>%
group_by(age = ifelse(age %in% c('70+', '70-79', '80+'), '70+', age)) %>%
summarise(across(`2020`:`2017`, sum, na.rm = TRUE)) -> result
result
的内容,如果用户按下返回按钮,它将删除快餐栏。
默认情况下,它将指定aggregate(.~age, transform(df,
age = ifelse(age %in% c('70+', '70-79', '80+'), '70+', age)),
sum, na.rm = TRUE)
原因
导入“ package:flutter / material.dart”;
