How do I show all radio buttons but only one dropdown. This shown dropdown is one that reflects the currently selected radiobtn?
Html:
<form ng-app="app" ng-controller="Ctrl">
<div class="color-pick" ng-repeat="(key, val) in productData.colors_and_sizes.data">
<input type="radio" name="colors" ng-model="myColor" ng-value="{{key}}" />{{key}}
<div class="size-pick">
<select ng-model="mySize" ng-options="size for size in val.sizes.split(',')"></select>
</div>
</div>
</form>
javascript:
var app = angular.module("app", []);
app.controller('Ctrl', function ($scope, $filter, $http) {
$scope.productData = {
"colors_and_sizes": {
"data": {
"Black": {
"sizes": "X Small, Small, Medium, Large, Xlarge, XX Large"
},
"Blue": {
"sizes": "X Small, Small, Medium, Large, Xlarge, XX Large"
}
}
}
};
});
Use the ng-hide or show directive on the div wrapping the select statement. The problem you're probably running into is that each ng-repeat iteration creates it's own scope, this means that each ng-model you create is completely independent.
You can see this here: http://jsfiddle.net/v2r9y6x2/ , when each select radio is clicked it prints a different value underneath itself, in both cases this is the value of ng-Model being set:
You can fix this by referring to the parent scope with $parent.property instead of just the property name. This will assign the value to the parent controllers scope and work as you expect.
<form ng-app="app" ng-controller="Ctrl">
<div class="color-pick" ng-repeat="(key, val) in productData.colors_and_sizes.data">
<input type="radio" name="colors" ng-model="$parent.myColor" ng-value="key" />{{key}}
<div class="size-pick" ng-show="$parent.myColor==key">
<select ng-model="$parent.mySize" ng-options="size for size in val.sizes.split(',')"></select>
</div>
</div>
myColor: {{myColor}}<br/>
mySize: {{mySize}}
</form>
