I am making an app, the user can either select an item or use their camera to get the qr code which translates into an item's ID.
The problem is that I think some JQuery is messing with my scope from working properly.
I have to get the QR code by listening to an innerHtml change, once it changes (DOMSubtreeModified) the following occurs.
var index = 0;
$('#result').one('DOMSubtreeModified', function(e) {
var code = "";
if (e.target.innerHTML.length > 0) {
code = e.target.innerHTML;
$scope.ToRun(code);
}
});
$scope.ToRun = function(code) {
for (i = 0; i < $scope.plantList.length; i++) {
if ($scope.plantList[i].plantcode == code) {
index = i;
break;
}
}
$scope.currentPlant = $scope.plantList[index];
$scope.plantDetails = false;
$scope.searchDetails = true;
}
For some reason the following does not have any effect on my ng-classes. As when an item is selected I hide the input dialogs, and show the result one.
$scope.plantDetails = false;
$scope.searchDetails = true;
But when a user selects the item manually it works just perfectly. (the items have an ng-click on it)
$scope.viewPlant = function(plant) {
$scope.currentPlant = plant
$scope.plantDetails = false;
$scope.searchDetails = true;
};
And the above works fine, with the ng-click. So why won't my new function that listens for an innerHtml change work?
HTML snippet
<div ng-class="{ 'hidden': searchDetails }">
<!-- CHOOSE INPUT TYPE -->
<div class="form-group" style="margin-bottom:0px">
<div class="btn-group btn-group-justified">
<div class="btn-group">
<button type="button" class="btn btn-default" ng-click="digits = false; qr = true">Plant Code</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-default" ng-click="digits = true; qr = false">QR Code</button>
</div>
</div>
</div>
<br />
<!-- QR CODE INPUT -->
<div ng-class="{ 'hidden': qr }">
<img id="blah" src="./images/placeholder.png" />
<span class="btn btn-default btn-file">
<i class="glyphicon glyphicon-camera"></i>
<input type="file" onchange="readURL(this);handleFiles(this.files)">
</span>
<div id="result">xxxxxx</div>
<canvas id="qr-canvas" width="800" height="600"></canvas>
</div>
<!-- MANUAL SELECTION INPUT -->
<div ng-class="{ 'hidden': digits }">
<input ng-model="search.$" style="width:100%; font-size:30px; text-align:center" placeholder="Plant Code" />
<div style="overflow: auto; max-height:250px">
<table class="table table-striped" style="background-color:lightblue">
<tr ng-repeat="plant in plantList | filter:search" ng-click="viewPlant(plant)" style="cursor:pointer">
<th>{{plant.name}}</th>
<th>{{plant.plantcode}}</th>
</tr>
</table>
</div>
</div>
<div>
</div>
</div>
<div ng-class="{ 'hidden': plantDetails }">
// results - this should appear when one of the above is entered.
// works for manual selection, but not qr code
</div>
Just confused on why my QR input will not fire off the change-class options to hide the searchDetails div and show the plantDetails div
EDIT: Doing a small test, it seems that my class variables are indeed not updating at all. I just put the values at the bottom of my page and they do not update when hitting the block of:
$scope.plantDetails = false;
$scope.searchDetails = true;
