AngularJS ng-value 和 ng-model 不能一起工作 [英] AngularJS ng-value and ng-model do not work together

问题描述

我试图使用 ngvalue 为 textfield 赋值，而 textarea 具有该值，但是当我提交时，它识别为 textarea 为空.

I was trying to give a value to textfield using ngvalue and textarea has that value but it when I submit it, it recognized as textarea is empty.

 <textarea  ng-value="main.record.basic_info.application_letter"
            class="form-control" 
            ng-model="main.record.apply_job.cover_letter" 
            name="name" rows="15" cols="80" style="resize: none">
 </textarea>

推荐答案

这些指令不能一起使用

它还可以用于实现给定表达式与输入元素(例如 input[text] 或 textarea)的单向绑定，当该元素不使用 ngModel 时."

"It can also be used to achieve one-way binding of a given expression to an input element such as an input[text] or a textarea, when that element does not use ngModel."

您应该在控制器中设置此值，而不是使用 ng-value.

You should set this value in your controller rather than use ng-value.
