We left off a while back discussing the various built-in Date Objects that JavaScript has to offer. Prior to that we talked about String Objects and JavaScript Events. Here and now, we are going to go over the Array Objects, which we can use to manipulate arrays. We will start off by viewing a table of them and the definitions of each. After that we will begin with the concat() method and try our best to work our way through the remaining thirteen.
JavaScript: Array Objects - Using Pop() to Assign a Value to a Variable (Page 4 of 5 )
You can also use the pop() function to assign a value to a variable, like so:
<html>
<body>
<script type="text/javascript">
var bboys = new Array(3);
bboys[0] = "Greg";
bboys[1] = "Bobby";
bboys[2] = "Peter";
yeah=bboys.pop();
document.write(yeah);
</script>
</body>
</html>
Here we have the result:
Peter
Push() Damn You Push!
Just as we use pop() to remove an element, we use push() to add one (or more) elements to the right side (or end) of an array and then print out the modified array length. Here is an example in which a Brady nightmare comes true and Michael Jackson joins the family:
<html>
<body>
<script type="text/javascript">
var bboys = new Array(3);
bboys[0] = "Greg";
bboys[1] = "Bobby";
bboys[2] = "Peter";
document.write("Behold the Brady Boys: " + "<br />");
