Question

我看到了很多回复，但都使用了$scope

我有几个ng-models有几个按钮来增加或减少值，我想只使用一个函数。

像这样：

＆＃13;

app = angular.module("myApp",[]);

app.controller("myCtrl", mainFunction);

function mainFunction(){
  scope = this;
  this.value1 = 3;
  this.value2 = 5;
  this.addOne = function (control) {
        if (scope.control <12){
            scope.control += 1;
        }
    }

    this.dimOne = function (control) {
        if (scope.control > 1) {
            scope.control -= 1;
        }
    }
  }

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp"  ng-controller="myCtrl as vm">

   <span>{{vm.value1}}</span>
   <button ng-click="vm.dimOne('value1')">-</button>
   <button ng-click="vm.addOne('value1')">+</button>
   <br />
   <span>{{vm.value2}}</span>
   <button ng-click="vm.dimOne('value2')">-</button>
   <button ng-click="vm.addOne('value2')">+</button>
  
</div>

＆＃13;

Answer 1

只需传递实际的model： -

<button ng-click="vm.dimOne(vm.value2)">-</button>

*.js

this.dimOne = function (control) {
    if (control > 1) {
        control -= 1;
        this.value2 = control ;
    }
}

Answer 2

由于您似乎传递了所需的字符串，只需更新您的功能：

package com.github.biniama

class TestController {

  TestService testService

  def index() {
    Integer result = testService.getData()
    render "Returned value is ${result}"
  }
}

另外......你的html应该是这个吗？

this.addOne = function (control) {
    if (scope[control] < 12) {
        scope[control] += 1;
    }
}

this.dimOne = function (control) {
    if (scope[control] > 1) {
        scope[control] -= 1;
    }
}

如何在没有$ scope的ng-click中将ng-model传递给函数
