Question

jq点击事件为什么只执行一次

<script>
var list = $("#content").children();
var listt = $("#content").children().find('span');
var len = list.length;
var index = 0;
var interval = null;
$("#begin").on('click',type);
function type() {
if(this.running) return;
this.running = true;
this.remain = 5000 + Math.random() * 1000;
interval = setInterval(function() {
if(begin.remain < 500) {
clearInterval(interval);
} else {
listt[index].className = "";
list[index].className = "";
list[(index + 1) % len].className = "current";
listt[(index + 1) % len].className = "span";
index = ++index % len;
begin.remain -= 100;
}
}, 100)
}
</script>
