I'm a little bit confused with Angular and ng-options
.
I have a simple array and I want to init a select with it. But, I want that options value = label.
$scope.options = ['var1', 'var2', 'var3'];
<select ng-model="myselect" ng-options="o for o in options"></select>
What I get:
<option value="0">var1</option>
<option value="1">var2</option>
<option value="2">var3</option>
What I want:
<option value="var1">var1</option>
<option value="var2">var2</option>
<option value="var3">var3</option>
So I tried:
<select ng-model="myselect2" ng-init=0 ng-options="options[k] as v for (k,v) in options"></select>
<select ng-model="myselect3" ng-init=0 ng-options="b as b for b in options"></select>
(But it didn’t work.)
My form is submitted externally, which is why I need 'var1' as the value instead of 0.
This question is related to
angularjs
ng-grid
ng-options
you could use something like
<select ng-model="myselect">
<option ng-repeat="o in options" ng-selected="{{o==myselect}}" value="{{o}}">
{{o}}
</option>
</select>
using ng-selected you preselect the option in case myselect was prefilled.
I prefer this method over ng-options anyway, as ng-options only works with arrays. ng-repeat also works with json-like objects.
You can use ng-repeat
with option
like this:
<form>
<select ng-model="yourSelect"
ng-options="option as option for option in ['var1', 'var2', 'var3']"
ng-init="yourSelect='var1'"></select>
<input type="hidden" name="yourSelect" value="{{yourSelect}}" />
</form>
When you submit your form
you can get value of input hidden.
<select ng-model="option" ng-options="o for o in options">
$scope.option will be equal to 'var1' after change, even you see value="0" in generated html
If you setup your select like the following:
<select ng-model="myselect" ng-options="b for b in options track by b"></select>
you will get:
<option value="var1">var1</option>
<option value="var2">var2</option>
<option value="var3">var3</option>
