Refactoring for each statement

Hi I have written a function that is used to change text in a table cell, the table displays members of a team but is not in a readable format, so i have to convert the string output into a read开发者_运维技巧able format.

This all works fine however I was wondering if anyone could help me re-factor this function as it seems abit crude ?

Jquery Code:

$(".membersName").each(function() {

   var memberName = $(this).text();
   var splitmemberName = memberName.split("=");
   var finalNameSplit = splitmemberName[1].split(",");
   $(this).empty();
   $(this).append(finalNameSplit[0]);


});

Any help or tips would be greatly appreciated. Cheers in advance

Looks fine to me! You could use RegExp instead, but I can't say that would be better. Although this:

$(this).empty(); 
$(this).append(finalNameSplit[0]); 

Could be shortened up to this:

$(this).empty().append(finalNameSplit[0]); 

Try this: http://jsfiddle.net/C9fMN/

$(".membersName").each(function() {
    $(this).text(function(i,txt) {
        return txt.split("=")[1].split(",")[0];
    });
});

No need to use .empty() this way, since you're replacing the text altogether.

In fact, this way, you really don't even need the call to .each():

http://jsfiddle.net/C9fMN/1/

$('.membersName').text(function(i,txt) {
    return txt.split("=")[1].split(",")[0];
});

just one:

$(".membersName").html(function(i, old) {
    var eqpos = old.indexOf("=");
    return old.substring(eqpos+1, old.indexOf(",", eqpos));
});​

Chaining can help you a bit in places, for example:

$(this).empty();
$(this).append(finalNameSplit[0]);

Can become

$(this).empty().append(finalNameSplit[0]);

Also, try caching $(this) for increased performance, i.e.

var $this = $(this);

Technically, you could amalgamate these lines:

var memberName = $(this).text();
var splitmemberName = memberName.split("=");
var finalNameSplit = splitmemberName[1].split(",");

Like so:

var finalNameSplit = $(this).text().split("=")[1].split(",");

Which means you could write it in one line of code:

$(this).empty().append($(this).text().split("=")[1].split(",")[0]);

Although your version is much more readable.
