Please note that :

请注意:

setplacementdataValue()
getplacementdataValue()

These are methods and not variables.

这些是方法而不是变量。

So use them as :

所以使用它们:

setplacementdataValue([Your Array Input]);
console.log(getplacementdataValue());

Note the parenthesis.

注意括号。

Also in your set method, use a different input parameter name.

同样在set方法中,使用不同的输入参数名称。

var app = angular.module("myApp", []);

app.controller('PriorityPlacement', ['myplacementdata',
  function(myplacementdata) {
    myplacementdata.setplacementdataValue([1, 2, 3]);
    console.log(myplacementdata.getplacementdataValue());
  }
]);

app.controller('Overview', ['myplacementdata',
  function(myplacementdata) {
    console.log(myplacementdata.getplacementdataValue());
  }
]);

app.service('myplacementdata', function() {
  var placementdata = [];
  this.getplacementdataValue = function() {
    return placementdata;
  }
  this.setplacementdataValue = function(myplacementdata) {
    placementdata = myplacementdata;
  }
})

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
  <div ng-controller="PriorityPlacement">
  </div>
  <div ng-controller="Overview">
  </div>
</div>

First off try changing

首先尝试改变

myplacementdata.setplacementdataValue=response.Data;

 myplacementdata.setplacementdataValue(response.Data);

And where do u get the response.Data from?

你从哪里得到response.Data来自?

try using a factory instead. like so.

尝试使用工厂代替。像这样。

app.factory('myplacementdata', function () {
    var mydata = {

      placementdata = [],
      getplacementdataValue:function () {
         return mydata.placementdata; 
      },
      setplacementdataValue: function (data) {
        mydata.placementdata = data;
      }
    }
    return mydata;
});
