EmberJS 路由器將控制器的屬性映射到不同的查詢參數(shù)鍵

2018-01-04 10:52 更新

描述

控制器具有將綁定到查詢參數(shù)的默認(rèn)查詢參數(shù)屬性，并且您可以將控制器屬性映射到不同的查詢參數(shù)鍵。

語(yǔ)句

Ember.ArrayController.extend({
   queryParams: {
      queryParamName: "Values"
   },
   queryParamName: null
});

            queryParma: Ember.computed.oneWay('query'),

                  addQuery: function() {

               }
            });

輸出

讓我們執(zhí)行以下步驟，看看上面的代碼如何工作：

將上面的代碼保存在routing_map.html文件中
在瀏覽器中打開此HTML文件。

以上內(nèi)容是否對(duì)您有幫助：
