javascript - Match a string using a regular expression -

-

मेरे पास निम्न स्ट्रिंग है 

  name = cvbb & source = Mamma + Mia & startdate = 2014-03-24   
 मैं नियमित अभिव्यक्ति के साथ नाम से संबंधित मान से कैसे मेल कर सकता हूँ, अर्थात् स्ट्रिंग "cvbb"  
 / [^ name]  = [^ & Amp;]  / मैचों = सीवीबीबी लेकिन मुझे केवल सीवीबीबी चाहिए   
 
 
 यह ऐसा लगता है कि आप URL पैरामीटर मान प्राप्त करना चाहते हैं? इस मामले में आप इस फ़ंक्शन का उपयोग कर सकते हैं:  
  फ़ंक्शन getParameterByName (नाम) {name = name.replace (/ [\ [] /, "\\ [")। Replace (/ [\ ]] /, "\\]"); var regex = नया RegExp ("[\\? & amp;]" + name + "= ([^ & amp; #] *)"), परिणाम = regex.exec (location.search); रिटर्न परिणाम == नल? "": डिकोडुरिक घटक (परिणाम [1] .replace (/ \ + / g, "")); } Var value = getParameterByName ('शुरुआती');   
 यह  2014-03-24  नामित एक var में  मान     डाल देगा

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] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
