此功能可以帮助您控制多个 Ajax 请求,并且它具有超时功能,可以在 ex 后将标志状态返回为 0。10 秒(如果服务器响应时间超过 10 秒)
var Request_Controller = function(Request_Name = '', Reactivate_Timeout = 10000)
{
var a = this;
a.Start_Request = function(){
if(window.Requests == undefined){
window.Requests = {};
}
window.Requests[Request_Name] = {'Status' : 1, 'Time': + new Date()};
}
a.End_Request = function(){
if(window.Requests == undefined){
window.Requests = [];
}
window.Requests[Request_Name] = undefined;
}
a.Is_Request_Running = function(){
if(window.Requests == undefined || window.Requests[Request_Name] == undefined){
return 0;
}else{
var Time = + new Date();
// Reactivate the request flag if server take more than 10 sec to respond
if(window.Requests[Request_Name]['Time'] < (Time - Reactivate_Timeout))
{
return 0;
}else{
return 1
}
}
}
}
要使用它:
var Request_Flag = new Request_Controller('Your_Request_Name');
if(!Request_Flag.Is_Request_Running()){
Request_Flag.Start_Request();
$.ajax({
type: "POST",
url: "/php/auth/login.php",
data: $("#login-form").serialize(),
success: function(msg) {
//stuffs
},
complete: function() {
Request_Flag.End_Request();
}
});
}
