How to delete an entry using JavaScript?
✍: Guest
The "delete" operator removes an array element, but oddly does not change the size of the array.
<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>
This produces
Number of days:7
Number of days:7
