I'm trying to figure out why my code isn't functioning properly. Is there a mistake I'm not seeing?
window.onload = function randomizeColor() {
var links = document.getElementsByTagName('a');
var colors = new Array("green","red","blue");
var randomColor = colors[Math.floor(colors.length * Math.random())];
for (var i = 0; i < links.length; i++) {
links[i].style.color = randomColor;
}
}
'randomColor' -> randomColor.
Replace the quoted string with a variable. Make sure each link gets a random color by generating the color within a loop:
for (var a = 0; a < links.length; a++) {
var randomColour = colours[Math.floor(colours.length * Math.random())];
links[a].style.color = randomColour;
}
To reduce the delay between color setting and link parsing, attach a DOMContentLoaded event, or insert the code at the end of the <body>:
<a>Test</a>
...
<a>Test</a>
<script>
(function() { // <-- Anonymous function to avoid global scope pollution
var links = document.getElementsByTagName('a');
var colours = ["green", "red", "blue"];
for (var a = 0; a < links.length; a++) {
var randomColour = colours[Math.floor(colours.length * Math.random())];
links[a].style.color = randomColour;
}
})();
