Angular to control printing , no. of times? - angularjs

Question

I do have a print Service developed using angular js,
Is there any efficient way that I can mention the no.of times.
Currently I can loop through this code and call n number of times
PrintService.printElement("printThisElement");
Print service code
function printElement(elem) {
var printSection = document.getElementById('printSection');
// if there is no printing section, create one
if (!printSection) {
printSection = document.createElement('div');
printSection.id = 'printSection';
document.body.appendChild(printSection);
}
var elemToPrint = document.getElementById(elem);
//clones the element you want to print
var domClone = elemToPrint.cloneNode(true);
printSection.innerHTML = '';
printSection.appendChild(elemToPrint);
$timeout(function(){
window.print();
}, 0);
window.onafterprint = function() {
printSection.innerHTML = '';
}
};
Can I loop thru this ?
$timeout(function(){
window.print();
}, 0);

Answer 1

Not sure of your question but from what I understand, your PrintService can be called from various controllers within your app. And you want to control the number of times this method can be called.
You can use a global variable, and check its value inside the PrintService.printElement("printThisElement"); method. If the value exceeds your limit, return an error.
var myApp = angular.module('myApp', []);
myApp.value('test', 0);
myApp.factory('PrintService ', ['test', function (test) {
this.printElement = function () {
//check 'test' value and then run print code
//test++ if printing
}
}]);

$timeout does not loops the function, $timeout used to execute the code inside it only once after a time out.
Instead use a variable to loop using if condition.
HEre is an example:
var count = 0;
function myFunction() {
count++;
if(count > 5)
{
return; // you can either return or execute any other code.
}
else
{
window.print();
}
}
