有关angularjs中ng-repeat循环中ng-model的问题
我是angularjs的入门选手,现在在项目中遇见这样的一个问题 在angularjs中ng-repeat循环一个表单内容, 产生的多个表单内都使用相同名字的ng-model内容,根据angular的双向数据绑定的原因 改一个内容就会更新全部的,我想知道有没有好的解决方案。请各位大牛们给予解答。
循环代码
这是输入后的效果

Texeure是在全局scope下面的,而repeat里面有自己的scope,这个scope“继承”全局的scope。
input的model应该使用repeat里的scope有效的变量。
你可以这样写
<code><div ng-init="Texture = [{value : '牙膏',price : 10},{value : '牙刷',price : 1}]"> <div ng-repeat="item in Texture"> {{item.value}}:{{item.price}} <input type="text" ng-model="item.price"> </div> </div> </code>
不会的,ng-repeat
会对每个数组生成一个$$hashKey
,会定位到每个数组,所以改一个不会更新全部
