如何在Polymer中进行onchange事件 [英] How to make onchange event in Polymer

问题描述

我收到此消息 TypeError:document.addEventListener(...)不是函数

(document.addEventListener('polymer-ready',function($){
 console.log('ready')
   // top link
   $.each(decodeURI(location.pathname).split('/'), function() {
      $("#self").html(this+'');
   });

   // browser default lang
   default_lang = navigator.language /* Mozilla */ || navigator.userLanguage /* IE */;

   // does URL contain lang=xx ?
   $.each(decodeURI(location.search.substr(1)).split('&'), function() {
     var s = this.split('=');
     if (s[0]=="lang") default_lang = s[1];
   });

   // toplevel = earth
   $("#earth").click(
     function(e) {
        e.preventDefault();
        //location.href = "http://www.geonames.org";
     }
  );

  // entry point
  geo_click($("#earth"));
}))(jQuery);

有人可以告诉我这是怎么回事吗?

Can someone tell me what is wrong with that?

推荐答案

问题已解决！

function geoready(){
console.log('ready');
// top link
$.each(decodeURI(location.pathname).split('/'), function() {
  $("#self").html(this+'');
});

// browser default lang
default_lang = navigator.language /* Mozilla */ || navigator.userLanguage /* IE */;

// does URL contain lang=xx ?
$.each(decodeURI(location.search.substr(1)).split('&'), function() {
    var s = this.split('=');
    if (s[0]=="lang") default_lang = s[1];
});

// toplevel = earth
$("#earth").click(
    function(e) {
        e.preventDefault();
        //location.href = "http://www.geonames.org";
    }
);

// entry point
geo_click($("#earth"));
}

然后将其绑定到Polymer构造函数中:

And I bind that in the Polymer constructor:

 <script>
    Polymer({
        is: "geo-dropdown",
        ready: geoready
    });
</script>
