Question

 <table border="0"  class="commentbox">
   <tr>
     <td>
          <div id="comment-f78d0b00-a008-473d-b647-a4a103ee3778"></div>
         <input type="button" class='btnReply' id="reply-f78d0b00-a008-473d-b647-a4a103ee3778" value="Reply"/>

     </td>
 </tr>
</table>

  $(".commentbox .btnReply").live("click", function () {
            //  $(this).hide();
            // i = 1;
            id = $(this).attr("id").split("-")[1]
            alert(id);
            var strDiv = 
             "<input type='text' class='txtCmnt' id='txtReply-" + id + "' /> 
        <input type='button' class='btnSave' value='Save' id='btnSave-" + id + "' /> ";
            $("#comment-" + id).append(strDiv);


        });

i want the f78d0b00-a008-473d-b647-a4a103ee3778 to come after split rather alert is giving
f78d0b00

I have tried to change id = comment_ f78d0b00-a008-473d-b647-a4a103ee3778 and split

id = $(this).attr("id").split("_")[1],but it doesnt work.

Edited

Input – container-f78d0b00-a008-473d-b647-a4a103ee3778

Output after split f78d0b00-a008-473d-b647-a4a103ee3778

Answer 1

A slightly convoluted means of achieving your end-result:

// splits the supplied string by the hyphen '-' character
var string = 'comment-f78d0b00-a008-473d-b647-a4a103ee3778'.split(/-/);
    // removes the zeroeth/first element from the string array
    string.shift();
    // joins the remaining elements from the string back together
var newString = string.join('-');
console.log(newString);​

Edited to turn the above into a function:

function splitString(haystack, needle){
    if (!needle || !haystack){
        return false;
    }
    var string = haystack.split(needle);
    string.shift();
    return string.join(needle);
}

// the first argument is the string you want to work on,
// the second is the character you want to split on
// f is the variable that will hold the new string
var f = splitString('comment-f78d0b00-a008-473d-b647-a4a103ee3778','-');
console.log(f);​
