使用AngularJS在ng-options中添加“％”后缀

Question

我希望使用ng-options在数组的选项中包含％符号。

以下是代码：

$scope.load_percentages = [0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50];

<select ng-model="loaddata.loadPercent" ng-options="loadpercentnumber as {loadpercentnumber + '%' +} for loadpercentnumber in load_percentages track by loadpercentnumber"> 
</select>

但是错误就像错误一样

Answer 1

不要使用支架：

ng-options="loadpercentnumber as loadpercentnumber + '%' for loadpercentnumber in load_percentages track by loadpercentnumber"

Answer 2

你几乎做对了。 使用：

<select ng-model="loaddata.loadPercent" name="loadPercent" ng-options="o as o+'%' for o in load_percentages"> 
</select>

请参阅this JSFiddle example。

Answer 3

尝试使用此代替实际的%符号：%
