[RPG/JS] Using setTimout
Posted: Wed May 31, 2017 5:20 am
Is it possible to use the setTimeOut javascript function within LongRange. What I'm trying to accomplish is that when a driver completes a delivery, the upload process would initiate in the event that the server is reachable. But in the event that the server is not reachable, I was trying to set up a periodical check so that when the server is reachable, then the upload would initiate. What I got doesn't work and it actually locks up LongRange I'm assuming is because I am closing the form so the driver can continue on.
Code: Select all
save = function () {
this.lrexec(
function () {
this.q_checkServerReachable(5);
},
function (reachable) {
if (reachable == true) {
// Delay 2 second to give current process time to finish
delay(2000);
} else {
delay(60 * 1000);
}
},
function () {
this.q_setProperty("RunOperation.Type", "CloseForm");
},
function () {
this.q_apply();
},
function () {
this.q_setProperty("RunOperation.Type", "CloseForm");
},
null
);
}
delay = function (delayTime) {
setTimeout(function () {
this.lrexec(
function () {
this.q_checkServerReachable(5);
},
function (reachable) {
if (reachable == true) {
upload();
} else {
delay(delayTime);
}
},
null
);
}, delayTime);
}
upload = function () {
this.lrexec(
function () {
this.console("Uploading...");
this.q_setProperties({
"RunOperation.Type": "PerformAction",
"RunOperation.Pgm": "MOR3598",
"RunOperation.Action": "",
"RunOperation.SendDBData": "Y"
});
},
null
);
}
) we would be able to have a "scheduled" process that would execute on a pre-determined schedule and not just based on the server re-establishing a connection. We have processes we want to kick off on a standard schedule even if the user is not actively doing anything in the app. If a delivery driver is driving across town for 30 minutes, we would like these "scheduled" processes updating/retrieving information from the server to occur anyway. Many native apps send alerts or notifications even when I am not using the app or when the device is in sleep mode so I'm wondering if there is any way at all to allow us to create similar background processes to run. Our processes would then check for server availability and act accordingly, but the process would activate on a predetermined schedule or frequency.
