这是《用AngularJS开发下一代Web应用》这本书里的一个例子,用来理解AngularJS的一些特性,MVC,其中输入框为Model,定义了ng-model后用来在输入框和item.quantity的值之间建立数据绑定关系,而{{}}这样的结构用来展现咱们在controller中定义的值。css
ng-repeat的意思是讲items的做用,不知道怎么说好,主要是用来循环提取items数组中每一个属性的值而后添加到dom中。html
button控件绑定的click事件用来移除当前行,ng-click在controller中定义,传入index的值用来达到移除的效果。chrome
前边这段话写的乱七八糟的。仅看成一个记录吧。segmentfault
