javascript - Regex to wrap in an anchor matched hashtags in description -

data model:

var sample = {desc: "i #cool #cool1234 hello world", tags:["cool", "cool1234"]} 

so able come function:

return sample.desc.replace(/#[a-z]+/g, "<a class=\"tags-in-details\" href=\"#/tab/myprofile-hashtags/$&\">$&</a>"); 

the problem function doesn't replace capitals "#cool" not linked , doesn't include numbers "#cool" linked without "1234".. in href desired url

href"#/tab/myprofile-hashtags/cool"  

instead of

href="#/tab/myprofile-hashtags/#cool" 

questions

1. what should regex upper case letters , numbers linked

2. how remove '#sign' in url (..url/cool instead of ..url/#cool)

screenshot app:

var sample = {desc: "i #cool #cool1234 hello world #notatag", tags:["cool", "cool1234"]};  var result = sample.desc.replace(/#(?:([a-za-z0-9]+))/g, function() {    var tag = regexp.$1;    if (sample.tags.indexof(tag) !== -1) {      return "<a class=\"tags-in-details\" href=\"#/tab/myprofile-hashtags/" + tag + "\">" + tag + "</a>";    }    return regexp.lastmatch;  });  snippet.log(result);
