You could use slice :
var val = $("#txtValue").val(),
txt = val.slice(-1) === ',' ? val.slice(0, - 1) : val;
$(".value").append(txt).attr("class", "values");

或使用正则表达式：
var str = 'Apple, Banana,'.replace(/,$/, '');

var string = "Apple,Banana,"; var lastIndex = string.lastIndexOf(","); if((string.length - 1) == lastIndex){ console.log(string.substring(0,lastIndex)); }

Another solution but regexp is a good method i think.
<html>
<head></head>
<body>
<script>
//Make a .trim() before
var stuff = "Apple, Banana,";
var result = (stuff.substr(stuff.length-1, 1) == ",")? stuff.substr(0, stuff.length-1):stuff;
alert(result);
</script>
</body>
</html>
