The issue arises when the AngularJS function is unable to properly update due to a

When I create a dropdown menu using ng-repeat, my function fails if the JSON data is in string format, but works fine with integers.

HERE IS AN EXAMPLE

As you can observe, the chart uploads successfully with the year selected from the dropdown as an integer value, like "year": 2011

However, when it comes to the quarter dropdown, having "quarter": "1" causes issues with updating, while "quarter": 2 functions properly.

<select class="YearSelector" ng-model="selectedyear" ng-change="sampleDropDown()">
      <option ng-repeat="year in filterOptions.stores |  unique: 'year'">
        {{ year.year }}</option>
    </select>
    Quarter:
    <select class="QuarterSelector" ng-model="$parent.quarter" ng-change="sampleDropDown()">
      <option ng-repeat="quarter in filterOptions.stores | unique: 'quarter'">
        {{ quarter.quarter }}</option>
    </select>

My function:

$scope.sampleDropDown = function(){
myChart.data = getData(data, $scope.selectedyear, $scope.quarter);
myChart.draw(500);

}

Answer №1

It appears that the formatting of your HTML code is causing the option values to have an extra carriage return. This issue can be observed by adding a console.log statement like the one below:

function getData(data, year, quarter) {
  console.log("year value '" + year + "'") ;

When viewing the console, you will notice:

"year value '
        2011'"

To resolve this problem, try adjusting your HTML option tags to be all on a single line, for example, when handling the quarter information:

<option ng-repeat ...>{{ quarter.quarter }}</option>

Another alternative could be utilizing Angular's ngOptions directive instead of combining option elements with ng-repeat.

Answer №2

I believe @charlietfl is suggesting that you simply convert your strings to numerical values.

 $scope.sampleDropDown = function(){
    myChart.data = getData(data,  parseInt($scope.selectedyear), parseInt($scope.quarter));
    myChart.draw(500);
  }

In my opinion, the issue appears to be related more to the myChart.draw function rather than Angular itself.
