javascript - ajax and php error : Undefined index: userid in my case -

-

मैं गलत कहां गया? 

  $ http ({url: "php / loaduser .fp? Userid = user_id ", विधि:" प्राप्त ", डेटा: {'user_id': '1'}})। सफलता (कार्य, डेटा, स्थिति, हेडर, कॉन्फ़िगरेशन) {mydata = []; mydata = data; Console.log (mydata);})। त्रुटि (फ़ंक्शन (डेटा, स्थिति, हेडर, कॉन्फ़िग) {// $ scope.status = स्थिति; चेतावनी (स्थिति);});   
 मेरे php  
  $ _GET ['user_id'] गूंज;   
 यह अपरिभाषित सूचकांक: user_id   
 
 
 आपका कॉल होना चाहिए जैसा कि  
  $ http ({url: "php / loaduser.php", विधि: "प्राप्त करें", डेटा: {'user_id': '1'}})   
 या फिर आप उपयोग कर सकते हैं  
  $ http ({url: "php / loaduser.php? User_id =" + user_id, विधि: "GET"})   
 दूसरी विधि में आप सीधे यूआरएल के माध्यम से  user_id  पारित कर रहे हैं, जबकि पहले इसे आप एक चर ढंग से भेज रहे हैं

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...
