JavaScript刪除陣列元素的方法_javascript技巧

本文實例講述了JavaScript刪除陣列元素的方法。分享給大家供大家參考。具體分析如下：

JS中可以透過delete刪除數組元素，但是刪除後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:7
Number of days:7

希望本文所述對大家的javascript程式設計有所幫助。
