splitting a string in js where a pattern DOES NOT match?

Question

i am trying to split a TextArea value where a pattern does not match

the text is like following:

Some Good Tutorials
http://a.com/page1
http://a.com/page2
Some Good Images
http://i.com/p1
http://i.com/p2
Some Good Videos
http://m.com/p1
http://m.com/p2

now i want to get only the links from the text so a better solution would be to split the whole string in an array of strings where the a line is not a url and then from amongst this array split each string with "\n"

edit:

okay i found a solution, i can find lines which does not begin with http:// or https:// and replace them with a good place holder after than i can get the links though i am weak in regex so can someone tell me how to do this in javascript?

Answer 1

Match the pattern. don't split with it.

value=value.match(/http\:\/\/.+/g)

(.+matches everything to the end of a line)

Answer 2

solved finally!

here is the code

function split_lines() { var oText = $('linkTxtArea').value;    removeBlankLines(); // a hepler function to remove blank linkes>    oText = oText.split("\n"); // first split the string into an array
for(i=0;i<oText.length;i++) // loop over the array  {       if( !oText[i].match(/^http:/) ) // check to see if the line does not begins with http:
    {           oText[i] = oText[i].replace(oText[i],"!replaced!"); // replace it with '!replaced!'         }   }

    oText = oText.toString().split("!replaced!");// now join the array to a string and then split that string by '!replaced!'   for( i = 1; i<oText.length;i++)     {       oText[i] = oText[i].replace(/^,/,"").replace(/,$/,"");// there were some extra commas left so i fixed it    }   return oText; // done }
