正则表达式不适用于JSP Java中的数字

Question

what I want is If the enter text box value is in format or not (1-10 number hyphen number) i did this for one pattern matching /^[\\d]+([-][\\d]+)?$/g but it allows only 0-9(single digits) i not taking 11-20(double digits) I need to allow any type digits like 10-11 and how can i do this

var txt =  document.getElementById("txtShareCount").value;      
        if(txt.match(/^[\d]+([-][\d]+)?$/g)){       
            return true;
            }           
        else if(!txt.match( /^[\d]+([-][\d]+)?$/g)){
            alert("Pleae Enter Share count this(1-10) format");
            document.getElementById("txtShareCount").focus();
            return false;
            }
        else{return true;}

Here i'm posting the OP post as executable snippet to show his code is working perfect . i said in comment he didn't accept that . so only i'm posting this snippet .

1) Additionally i applied only trim()

 $('#ss').click(function(){ var txt = $("#txtShareCount").val(); if(txt.trim().match(/^[\\d]+([-][\\d]+)?$/g)){ alert("hi valid format "); } else if(!txt.trim().match(/^[\\d]+([-][\\d]+)?$/g)){ alert("Pleae Enter Share count this(1-10) format"); $("#txtShareCount").focus(); return false; } else{ alert("hi valid format "); } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="inputt"><input type="text" id="txtShareCount" name="myanswer" class="myinput"></div> <input type="button" id="ss" value="submit" >
