如何使用新的详细信息删除现有的详细信息 [英] How to remove already existing details with the new one

问题描述

我使用ionic来显示列表中所选项目的小描述。这里的问题是当选择列表中的item1时它显示其描述，但同时当选择列表中的item2时，它也显示前一个和第二个的描述。我尝试了很多方法，但不能错过这个错误。

Im using ionic to display a small description of the selected item from the list. The problem here is when the item1 from list is selected it displays its description but at same time when the item2 from the list is selected it displays the description of previous one and second one also. I tried many ways but couldn't over come the mistake.

  $scope.items=[];
  $scope.carList = [{ value: "Bmw", description: "Its bmw" },
  { value: "Mercedes", description: "Its Mercedes" },
  { value: "Honda", description: "Its Honda" }];
  $scope.select_item = function (key) {
  $scope.items.push(key);

}

scope.items = [];

scope.items=[];

scope.carList = [{value： Bmw，description： 它的bmw}，
{值： Mercedes，description： 其梅赛德斯}，
{值： Honda，描述： 其本田}];

scope.carList = [{ value: "Bmw", description: "Its bmw" }, { value: "Mercedes", description: "Its Mercedes" }, { value: "Honda", description: "Its Honda" }];

scope.select_item = 功能（键）{

scope.select_item = function (key) {
