alert(str.split(",")[1])
...
alert(str.split(",")[str.length-1])
啥意思

Answer 2

<script>
var str = '45,47,24,40,63,94,90,86,61,106,';
var arr = str.match(/\d+/g);
alert(arr);
</script>

Answer 3

<script>
var str = '45,47,24,40,63,94,90,86,61,106,';

Answer 4

这就是啥意思的问头
var str = "45,47,24,40,63,94,90,86,61,106,";
alert(str.split(",",6))

Answer 5

var str = "45,47,24,40,63,94,90,86,61,106";alert(str.split(",")[0])
alert(str.split(",")[1])
alert(str.split(",")[2])
alert(str.split(",")[3])

Answer 6

稍微优化一点
var str = "45,47,24,40,63,94,90,86,61,106";
var arr = str.split(",");for (i=0; i<arr.length; i++) {
    alert(arr[i]);
    if (i == 5) return;
}

Answer 7

去掉,的前六个还是用,分的前六组?
<script>
var str = '45,47,24,40,63,94,90,86,61,106,';
//前六个
var f6 = str.replace(/,/g,'').slice(0,6);
alert(f6);//前六组
var f6g = str.split(',').slice(0,6);
alert(f6g.join('\n'));
</script>
