Removing all elements of an array in JavaScript
Removing all elements by making length zero.
We care read the number of elements in an array by using length property and we can set the length to zero. Here it is used to empty the array. <script type="text/javascript">
var scripts = new Array();
scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";
scripts[4] = "SQL";
document.write(scripts.join(","));
document.write("<br>--Now after emptying --<br>");
scripts.length=0; // Emptying all elements
document.write(scripts.join(","));
</script>
By re-declaring the array to new variable.
scripts = [];var scripts = new Array();
