Javascript Regular Expressions in RegEx -

here's problem. want replace "document 1", "document 12" strings in text hypertext link :

<a onclick="gotodocument(document7);">document 7</a> 

i tried code :

var reg=new regexp("((document )[a-za-z0-9/.]+)+\s(\w+)","gi"); var chaine= *thetext*;   var socle_contenu = chaine.replace(reg, "<a onclick=\"alleraudocument('$1');\"'>" + '$1' + "</a>"); 

the result :

 <a onclick="gotodocument(document 7);">document 7</a> 

as can see, problem space in onclick function.

i tried delete space want keep space human reader. couldn't make it.

i tried "document " , number in $1 , $2, in order contacatenate 2 variables need. tried :

var reg=new regexp("((document )\s(\w+))+", "gi"); 

but doesn't work ! can tell me how setup regular expression ?

thanks !

you use callback function replace. allows further manipulation of matches:

var s = 'document 12 more text document 7 end';  var re = new regexp(/(document\s?\d+)/gi);  s = s.replace(re, function($1){      return "<a onclick=\"alleraudocument('" + $1.replace(' ', '') + "');\">" + $1 + "</a>"; });
