Question

我想在ng-repeat块中更改对象后，向ng-model对象添加属性“discountRate”。

选择选项后，ng-model会按预期更新。但“discountRate”不会作为属性添加。显然我错过了一些关于“范围”的东西。如果有人对此进行调查，我怎样才能将“discountRate”属性添加到ng-model中？

<form class="form-horizontal" ng-submit="addToInvoice()">
    <div class="form-group">
        <label for="inputService" class="col-sm-2 control-label">Service</label>
        <div class="col-sm-4">
            <select name="data.itemToSave" class="form-control" required="required"
                    ng-options="option.title for option in items.services track by option.id"
                    ng-model="data.itemToSave"></select>
        </div>
    </div>

    <div class="form-group">
        <label for="inputPrice" class="col-sm-2 control-label">Discount</label>

        <div class="readonly" data-toggle="buttons">
            <label class="btn btn-default" ng-class="{active: '!data.itemToSave.discountRate'}">
                <input type="radio" ng-model="data.itemToSave['discountRate']" value="0">0%</label>

            <label class="btn btn-default">
                <input type="radio" ng-model="data.itemToSave['discountRate']" value="10">10%</label>

            <label class="btn btn-default">
                <input type="radio" ng-model="data.itemToSave['discountRate']" value="20">20%</label>
        </div>


    </div>
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-4">
            <button type="submit" class="btn btn-default">Add to Invoice</button>
        </div>
    </div>
</form>

删除data-toggle="buttons"使其有效，无论是否有ui.bootstrap

ng-change,ng-click don't work with data-toggle="buttons" since v1.3.0
