本文实例讲述了JavaScript删除数组元素的方法。分享给大家供大家参考。具体分析如下：
JS中可以通过delete删除数组元素，但是删除后数组的大小不会改变
<script type="text/javascript">
<!--
var days = ["Sunday","Monday","Tuesday","Wednesday",
"Thursday","Friday","Saturday"];
document.write("Number of days:"+days.length);
delete days[4];
document.write("<br />Number of days:"+days.length);
//-->
</script>
输出结果
Number of days:7 Number of days:7
希望本文所述对大家的javascript程序设计有所帮助。
