我正在使用棱角分明。我的输入看起来像:
Preferences
基本上当这个改变时,我想要改变div的背景颜色。
我的控制器有一些看起来像这样的行:
<input class="form-control" type="text" ng-model="newBook.color">
然后我要改变div:
$scope.newBook = {};
$scope.newBook.color = "";
$scope.color = ->
return "background-color: " + $scope.newBook.color;
但是,我收到错误:<div ng-style="{{color()}}"></div>

我在这里为你做了一个例子:https://jsfiddle.net/chelogui/2h3hrj1x/
HTML:
<div ng-app="appTest">
<div ng-controller="contr as controller">
<input class="form-control" type="text" ng-model="controller.color" />
<div id="divTest" style="background-color: {{ controller.color }}"></div>
</div>
</div>
Javascript:
angular.module('appTest', [])
.controller('contr', [function () {
var self = this;
self.color = "red";
}]);
Css例证:
#divTest {
width: 100px;
height: 100px;
border: 1px solid black;
margin-top: 10px;
}

这是一个有效的example:
您需要更改color
功能才能执行此操作:
angular.module('myApp',[])
.controller('myFirst',['$scope',function($scope){
$scope.newBook = {};
$scope.newBook.color = "red";
$scope.color = function(){
return "{'background-color' : '"+$scope.newBook.color+"'}";
}
}])
检查一下:
angular.module('myApp',[])
.controller('myFirst',['$scope',function($scope){
$scope.newBook = {};
$scope.newBook.color = "red";
$scope.color = function(){
return "{'background-color' : '"+$scope.newBook.color+"'}";
}
}])
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="myFirst" ng-style="{{color()}}">Ajay</div></div>
