EmberJS 路由器使用Replacestate更新URL

2018-01-04 10:51 更新

描述

它阻止在浏览器的历史记录中添加项目。您可以在路由的queryParams上指定此参数以配置哈希，并通过使用replace = true选择启用replaceState转换。

语句

Ember.Route.extend({
   queryParams: {
      queryParameterName: {
         replace: true
      }
   }
});

例子

<!DOCTYPE html>
<html>
   <head>
      <title>Emberjs Update URL with replaceState Instead</title>

   <body>
      <script type="text/x-handlebars">
         {{outlet}}
      </script>

      <script type="text/x-handlebars" data-template-name="index">
         <h2>Click to replaceState</h2>
         <button {{action 'change'}}>Replace State</button>
         {{query}}
      </script>

      <script type="text/javascript">
         App = Ember.Application.create();
            //declaring varialbe words with query parameter name
            var words = "tutorialspoint";
            App.IndexController = Ember.Controller.extend({
               queryParams: ['query'],
               actions: {
                  change: function() {
                     //assigning words value to the 'query' i.e. query parameter
                     this.set('query',words);
                  }
            }
         });

         App.IndexRoute = Ember.Route.extend({
            queryParams: {
               query: {
                  //assigning replace state as true
                  replace: true
               }
            }
         });
      </script>
   </body>
</html>
