Javascript 如何使jquery表每10秒刷新一次?
我正在制作管理员门户,管理员可以在其中查看当前预订的总数,为此,我们必须每10秒自动刷新一次表,还有刷新按钮,更新表,我使用JQuery、Ajax、Json、Spring MVC,这里还有一个问题,当我点击按钮时,它会重复信息。因此,请帮助我使这两件事自动刷新Jquery表格数据库和按钮,它也刷新信息,而无需重复信息,提前感谢您的帮助和任何建议 注意:多亏了Prog和ChrisH619,这是一个工作代码Javascript 如何使jquery表每10秒刷新一次?,javascript,jquery,ajax,json,Javascript,Jquery,Ajax,Json,我正在制作管理员门户,管理员可以在其中查看当前预订的总数,为此,我们必须每10秒自动刷新一次表,还有刷新按钮,更新表,我使用JQuery、Ajax、Json、Spring MVC,这里还有一个问题,当我点击按钮时,它会重复信息。因此,请帮助我使这两件事自动刷新Jquery表格数据库和按钮,它也刷新信息,而无需重复信息,提前感谢您的帮助和任何建议 注意:多亏了Prog和ChrisH619,这是一个工作代码 <!DOCTYPE html> <html> &l

您应该创建一个通用函数,该函数将从数据库中获取所有数据,如下所示
function fetchData(){
$(".data-contacts-js tbody").empty(); // this will remove all <tr>.
$.get("http://localhost:8080/Hotels/reservation/getAllBookingDetails", function(data) {
$.each(data, function(i, contact) {
$(".data-contacts-js").append(
"<tr><td>" + contact.custId + "</td>" +
"<td>" + contact.custName + "</td>" +
"<td>" + contact.custMobile + "</td>" +
"<td>" + contact.custEmail + "</td>" +
"<td>" + contact.custAddress + "</td>" +
"<td>" + contact.Date + "</td>" +
"<td>" + contact.Time + "</td></tr>"
);
});
});
}
$(document).ready(function(){
setInterval(function(){
fetchData();
},10000); // this will call your fetchData function for every 10 Sec.
});
第三步:
为刷新
按钮单击事件
创建一个事件函数,并将此函数放入.ready()
函数中
$('#fetchContacts').click(function() {
fetchData();
});
