chrome.extension.sendRequest（）;麻烦

Question

contenescript.js

var someText = 'some text to show1';
chrome.extension.sendRequest({'action' : 'openMyTab','text': someText});

background.html

function onRequest(request, sender, callback) {
        if (request.action == 'openMyTab') {
    alert(" Inside onRequest with  " + request.text);
        }
      };

chrome.extension.onRequest.addListener(onRequest);

这很好用。正如预期的那样，会发出警告信息。

但是将 contentscript.js 更改为类似的内容。

Wordlistonilne.Selector.dblClick = function(){
  var st = Wordlistonilne.Selector.getSelected();
  if(st!=''){
 myMethod('openMyTab',st);
  }
}


function myMethod(action,message){
 alert("myMethod : action = " + action + "message = " + message);
 chrome.extension.sendRequest({'action' : action,'text': message});
}

$(document).ready(function(){
  $(document).bind("dblclick", Wordlistonilne.Selector.dblClick);
});

我通过操作和消息获得警报。但是chrome.extension.sendRequest似乎没有用。
