I've been working with classes in a manner that I believe only works with the prototype.js (or prototype.lite.js) scripts, so a solution for this problem may be difficult or impossible to apply elsewhere. With that warning, here it is:
I'm looking for a way to list all class-based elements in the same way that one could list elements of a certian class (document.getElementsByClassName("aClass") ). Take, for example, this script:
<script type="text/javascript" src="prototype.js"></script>
<script type="text/javascript">
fighter = Class.create();
fighter.prototype = {
initialize: function(health, name) {
this.name = name;
this.health = health;
},
output: function() {
alert(this.name);
}
};
window.onload = function() {
a = new fighter(100,"Bob");
b = new fighter(200,"John");
c = new fighter(300, "Billy");
}
var a, b, c;
</script>
Note: this script was written entirely in-post, so I cannot test it and appologize if there are any scripting errors. The <html><body> etc. tags are not present for simplicity.
What I'm looking for is a way to list a, b, and c without having to place them into an array when I initialize them - in other words, by calling functions like this:
alert( document.getElementsByType("fighter").length );
I can't seem to find anything online that illustrates this capabilitiy in javascript. Is this even possible?
Thanks ahead of time :) -
Still havent figured out a way to do it, but if anyone's interested the 'lame' way works great.
Define an array at the root level so it's accessible anywhere in the code. Say
var fighters = new Array();
and then just go fighters(fighters.length) = new fighter(blabla);
