When using AngularJS (ng1), TypeScript, and PhoneGap on iOS, the <select> element may display the incorrect option, even though the model contains the correct one

framework: Angular 1

platform: iOS

On iOS, using a <select> element will cause the view to display the next <option> in the list once one is chosen, while the model will contain the correct value.

If the <select> element is pressed again, the option that the view was showing will be presented as the currently selected option. When selecting a different option, the view and the model seem to align correctly.

Creating Arrays in TypeScript:

ConfigureHairOptions() {
    this.HairOptions.Options.push({ Id: 0, Value: "Blonde" });
    this.HairOptions.Options.push({ Id: 1, Value: "Black" });
    this.HairOptions.Options.push({ Id: 2, Value: "Red" });
    this.HairOptions.Options.push({ Id: 3, Value: "Gray" });
    this.HairOptions.Options.push({ Id: 4, Value: "White" });
    this.HairOptions.Options.push({ Id: 5, Value: "Bald" });
    this.HairOptions.Options.push({ Id: 6, Value: "Brown" });
    this.HairOptions.Options.push({ Id: 7, Value: "Sdy" });
}

HairOptions is of type Selector:

interface Option {
    Id: number;
    Value: string;
}
class Selector {
    Options: Array<Option>
    Selected: Option;

    constructor() {
        this.Options = [];
    }
}

The views are bound like this:

<select ng-model="ctrl.HairOptions.Selected"
        ng-options="option.Value for option in ctrl.HairOptions.Options track by option.Id"
        class="lg-select">
</select>

The pickers that appear in browser and Android do not have this issue. I am not sure what is causing this problem on iOS. By default, nothing is selected which creates a blank value in the list, but this is not present when pressing the <select> element a second time. I suspect this is due to the platform, but I am unsure of the solution.

Answer №1

One suggestion is to consider incorporating a null option into your code:1

<select ng-model="ctrl.HairOptions.Selected"
        ng-options="option.Value for option in ctrl.HairOptions.Options track by option.Id"
        class="lg-select">
     <option value="" disabled>Select HairOption...</option>
</select>

This will prevent the blank value from being added and removed dynamically.
