Javascript 使用ng repeat动态多表单插入,每个表单都有动态文本框来获取值
我正在使用ng form和ng repeat进行动态表单插入,并尝试使用该表单中的文本框来存储多个动态值。 这是我的密码:Javascript 使用ng repeat动态多表单插入,每个表单都有动态文本框来获取值,javascript,angularjs,angularjs-scope,Javascript,Angularjs,Angularjs Scope,我正在使用ng form和ng repeat进行动态表单插入,并尝试使用该表单中的文本框来存储多个动态值。 这是我的密码: Want to add Ingredients : <button ng-click="showIngredientForm = !showIngredientForm" ng-class="{'red' : showIngredientForm}">{[{toggleText}]}</button> <div ng-show="showIn

欢迎任何类型的帮助,因为这将帮助我和其他程序员…您在输入类型中使用单个对象作为
ng model
,而使用具有多个键和值的对象,如ng model=“itemToAdd.ingredientName[formToAdd.ingrediend]”
这将为id创建一个唯一的键wrt,并将输入文本值分配给该键,从而避免在下一个表单字段中重复出现相同的值
添加track by
以跟踪列表中的对象,这将帮助我们在添加新字段时创建新的ng model
对象关键点
