Javascript & Build 8000-5628

[[email protected]]

Hi All

I installed Build 8000-5628 on the 2nd January and I am having problems that it won't execute javascript that has been working for the last 5 years

Two examples are below, I have recalculated all the controls on my UX taken sanitize off with no success I have loaded backups of the UX but still no joy.

Does anybody have any ideas of what I might try?

Andy

{dialog.Object}.setValue('Pay_Type','Cash');

var _ok = function() {
{dialog.object}.runAction('PayOnLine');
};

var _err = function() {
THE FUNCTION IS ALWAYS ENDING UP HERE AND ALERTING THAT IT DID NOT RESPOND
alert('server did not respond');
{dialog.object}.runAction('PayOffLine');
};

//wait up to 2000 milliseconds before calling either the _ok or _err callback function
{dialog.object}.serverIsAvailable(2000,_ok,_err);

 data = lObj._rData;
var html = '',
sttl = 0;
for (var i = 0; i < data.length; i++) {
html += '<LEFT><SMALL> ' + data[i].PRICE +' ' + data[i].NAME + '<br>'
sttl += +data[i].PRICE;
};



var _d = {"name": vStore,"Add1": vAdd1,"Add2": vAdd2,"City": vCity,"Pcode": vPostCode,"vat": vVAT,"paid": vTen,"Change": vChange,"Subtotal": vSub};

var _h = '<center><BIG>' + _d.name + '<br>';
_h += '<center><Small>' + _d.Add1 + '<br>';
_h += '<center><Small>' + _d.Add2 + '<br>';
_h += '<center><Small>' + _d.City + '<br>';
_h += '<center><Small>' + _d.Pcode + '<br><br>';

//footer part
var _f = '<BOLD><SMALL><LEFT>Sub Total VAT Total<br>';
_f += '<BOLD><SMALL><LEFT>' + _d.Subtotal + ' ' + _d.vat + ' ' + vTot + '<br>';
_f += 'Paid: ' + _d.paid + '<br>';
_f += 'Discount:' + vS_Dic + '<br>';
_f += 'Change: ' + vChange + '<br>';

 1
var dt = new Date().toDateString();
_f += 'Date: '+ dt + '<br>';
_f += 'Order: '+ vOrder + '<br>';
_f += 'Payment: '+ vpayment + '<br>';
_f += 'Discount:'+ vApplyDisc + '<br>';
//_f += 'Date: ' + dt.toFormat('dd/mm/yyyy') + '<br>';
_f += '<LINE><SMALL><LEFT>Thank you for your purchase. Please retain for your records. ';
_f += '<SMALL><LEFT> Please ensure you use the correct charging equipment for your device, mobile phone and tablet chargers can be dangerous.';
_f += '<br><CUT><DRAWER>';

//put it all together

var vReceipt = '<LOGO2>' + _h + html +'<br>' + _f
//alert(vReceipt);

CODE FAILS HERE
var sApp = startApp.set({
"action":"ACTION_SEND",
"type":"text/plain",
"component": ["pe.diegoveloper.printing"],
},
{"EXTRA_TEXT":vReceipt /*dataToPrint*/
});
sApp.start(function() { /* success */
console.log("PRINT OK");
},
function(error) { /* fail */
alert(error);
});

Yep ... I've run into lots of these type of issues in build 8000.
Another property you can try is turn off 'Temporarily lock event handlers' under the Advanced section.
Also turn on 'Pre-render component at design time' if it isn't on already.

Have you stepped through your code in a debugger? What error is shown in the browser console?

Hi Mike

This is what I see

Uncaught ReferenceError: cordova is not defined
at <anonymous>:1:1

This is the code I have in the Javascript functions, which has worked for five years but now it has stopped, has something changed Javascript is just not my thing, It's for printing to a receipt printer (ESC/POS) the startApp is in the code below

cordova.define("com.lampa.startapp.startapp", function(require, exports, module) {
/**
com.lampa.startapp
https://github.com/lampaa/com.lampa.startapp

Phonegap plugin for check or launch other application in android device (iOS support).
bug tracker: https://github.com/lampaa/com.lampa.startapp/issues
*/

var exec = require('cordova/exec');

module.exports = {
/**
* Set application params
*
* @param {Mixed} params params, view documentation https://github.com/lampaa/com.lampa.startapp
* @param {Mixed} extra Extra fields
* @param {Function} errorCallback The callback that is called when an error occurred when the program starts.
*
*/

set: function(params, extra) {
var output = [params];

if(extra != undefined) {
output.push(extra);
}
else {
output.push(null);
}

return {
start: function(completeCallback, errorCallback) {
completeCallback = completeCallback || function() {};
errorCallback = errorCallback || function() {};

exec(completeCallback, errorCallback, "startApp", "start", output);
},
check: function(completeCallback, errorCallback) {
completeCallback = completeCallback || function() {};
errorCallback = errorCallback || function() {};

exec(completeCallback, errorCallback, "startApp", "check", output);
},
go: function(completeCallback, errorCallback) {
completeCallback = completeCallback || function() {};
errorCallback = errorCallback || function() {};

exec(completeCallback, errorCallback, "startApp", "go", output);
}
}
},
/**
* extra values
*/
getExtras: function(completeCallback, errorCallback) {
exec(completeCallback, errorCallback, "startApp", "getExtras", []);
},
getExtra: function(extraValue, completeCallback, errorCallback) {
exec(completeCallback, errorCallback, "startApp", "getExtra", [extraValue]);
},
hasExtra: function(extraValue, completeCallback, errorCallback) {
this.getExtra(extraValue, completeCallback, errorCallback);
}
}

});

Any luck figuring this out?

if you cant use a nightly build go back pre 8000 to many issues in 8000

Hi

No I did not, I replaced the code with code just checking if I was online, I could not get the {dialog.object}.serverIsAvailable() to work consistently, I am also finding that on the AJAX callback setup I am having to uncheck the "Check Server is Available" if I don't it is timing out and reporting that my server is not online

[RustyB]

I've been having trouble with serverIsAvailable as well. Several users throughout the country are getting the message even when in a good coverage area. I figured it was something with AT&T. The funny thing is we are running version 7564 for IIS and have not updated recently. I did install 7902 when it came out for testing but never moved to it.

Hi

I am in the UK so nothing to do with AT&T this side of the pond

the server time is set to 2000 never going to happen change to 6000

the server time is set to 2000 never going to happen change to 6000

Thanks Pete. I considered changing the default time. My concern is if the client is not getting a response in 2 seconds, then they must not have a very good connection to begin with. Do we want to attempt a sync over a poor connection? Previously we found that if a user has a list they are trying to sync and that list contains a picture, if the sync fails, then all the edits are not persisted to the file system (in our case an Android tablet). Then if the user closes the app, all their edits are lost. We were having users losing work at an alarming rate. Checking serverIsAvailable first seems to have almost completely fixed this problem for us.

[RustyB]

Andy, I am seeing with some users that serverIsAvailable constantly fails even when in a good coverage area. But putting their tablet in airplane mode and then taking it out solves the problem and serverIsAvailable works after that. It is like the tablet is stuck in some type of offline mode even though it is not offline (I am able to offer remote support to the tablet fine).

Has you are anyone else noticed this behavior? I've noticed this in the past. As a work around I used to run code {dialog.Object}._setSimulatedOnlineStatus('on') which would kind of trick the tablet into thinking it was online before trying a sync. This doesn't seem to be as effective anymore.
