angularjs - 返回JSONP时不执行HTTPpromise

Question

我试图从雅虎的api获得股票报价,我正在使用angular的$ http.jsonp方法.目标是当结果返回时,让应用程序转到这条路线:'/ stocks/show_stock'.我试图以两种方式做到这一点并且都不起作用1)我发表声明:

window.location = '/stocks/show_stock'

在包装JSONP响应的回调函数中2)我把语句:

$location.path '/stocks/show_stock'

在HTTPpromise回调中.(参见代码中的注释)

这是我的代码(在coffescript中):

#THIS IS THE CALLBACK FUNCTION THAT I SEND WITH THE JSONP REQUEST  
window.stock_quote_callback = (data)->
  console.log data #THIS WORKS AND I CAN SEE THE DATA RETURNED FROM YAHOO
  window.stock_quote_result = data.results
  alert 'I am in the callback'
  #THE STATEMENT BELOW DOES NOT WORK EVEN THOUGH I CAN SEE THE ALERT ABOVE
  window.location = '/stocks/show_stock'

angular.module('Services').service 'StockSupplier', ($http)->
  get_stock = (symbol)->
    q = 'select * from yahoo.finance.quotes 
        where symbol in ("'+symbol+'")
        &format=json&
        diagnostics=true&
        env=http://datatables.org/alltables.env&
        callback=stock_quote_callback'
    url = 'http://query.yahooapis.com/v1/public/yql?q='+q 
    $http.jsonp(url).then (data)->
      #THE CODE BELOW NEVER EXECUTES EVEN THOUGH RESULT IS RETURNED
      alert 'This should pop up when result returns'
      $location.path'/stocks/show_stock'

  {
    get_stock: (symbol)-> get_stock(symbol)
  }

先感谢您.
