本文實例講述了JavaScript刪除數組元素的方法。分享給大家供大家參考。具體分析如下：
JS中可以通過delete刪除數組元素，但是刪除后數組的大小不會改變
<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>輸出結果
Number of days:7Number of days:7
希望本文所述對大家的javascript程序設計有所幫助。
