Bind input value to ng-click button (send value as parameter)
提问by btmach
I'm trying to bind the value from an input field to the parameter of my method on ng-click. Here's what I got, but it doesn't work, and I am not too sure if it's possible to do it this way?:
我正在尝试将输入字段中的值绑定到我在 ng-click 上的方法的参数。这是我得到的,但它不起作用,我不太确定是否可以这样做?:
<input type="text" name="name" value="{{post.PostId}}" />
<button ng-click="getById(post.PostId)"></button>
<h1>{{post.Title}}</h1>
$scope.getById = function (id) {
console.log(id);
return $http.get('/api/Post/' + id);
}

You should use ng-model
directive for your input element.
您应该ng-model
为输入元素使用指令。
Markup
标记
<input type="text" name="name" ng-model="post.PostId" />
<button ng-click="getById(post.PostId)"></button>
<h1>{{post.Title}}</h1>
This will take care of 2-way model binding to your property post.PostId
. Your ng-click
directive will pick up the correct value entered in input element.
这将处理到您的 property 的 2-way 模型绑定post.PostId
。您的ng-click
指令将选取在 input 元素中输入的正确值。
