我有一个表格,我列出了一些带有输入的产品,基本上我想要的是在另一个更改时更改输入值,这里是<tr>
:
<tr ng-repeat="bought_product in vm.bought_products track by bought_product.id">
<td>
{{ bought_product.name }}
</td>
<td>
<input type="number" class="form-control"
min="1" max="1000" placeholder="#"
ng-model="bought_product.quantity">
</td>
<td>
<div class="input-group">
<span class="input-group-addon">$</span>
<!-- This is the input where I'll insert a price -->
<input type="number" class="form-control no-spin"
min="1" max="1000" placeholder="#" ng-change="vm.calculateVatPrice(bought_product.price)"
ng-model="bought_product.price">
</div>
</td>
<td>
<div class="input-group">
<span class="input-group-addon">$</span>
<!-- This input will automatically be filled -->
<input type="number" class="form-control no-spin"
min="1" max="1000" placeholder="#"
ng-model="bought_product.vat_price">
</div>
</td>
</tr>
答案 0 :(得分:1)
您必须更换
ng-change="vm.calculateVatPrice(bought_product.price)"
通过
ng-change="vm.calculateVatPrice(bought_product)"
在你的vm.calculateVatPrice函数中你必须像这样计算和设置vat_price
calculateVatPrice = function (product) {
product.vat_price = product.price * 1.18;
}
当然,您必须用实际的业务逻辑来替换它来计算增值税价格。
所以诀窍是交出对产品对象的引用并相应地更新值。
