my text editor does not like this piece of code I am not sure why
<script type="text/javascript">
function randmg(){
var img = [
"banner1.png",
"banner2.png",
"banner3.png",
"banner4.png"
]
var maxImg = img.length;
var randNum = Math.floor(Math.random()*maxImg)
return img[randNum]
}
</script>
It says the error is in line four "var img - ["
I thought that i was the use/placement of var under the array but I have not been able to fix it
Changed to this
function randmg(){
var img = ["banner1.png","banner2.png","banner3.png","banner4.png"];
var maxImg = img.length;
var randNum = Math.floor(Math.random()*maxImg);
return img[randNum];
}
But still having the same issue
yes, you need to add a semicolen at the end of that array.
var img = [
"banner1.png",
"banner2.png",
"banner3.png",
"banner4.png"
];
You should have semicolons and the end of each statement:
function randmg(){
var img = [
"banner1.png",
"banner2.png",
"banner3.png",
"banner4.png"
]; //here
var maxImg = img.length;
var randNum = Math.floor(Math.random()*maxImg); //here
return img[randNum]; //here
}
Although they aren't required due to legacy reasons, they are strongly encouraged. In this case the code runs, but that is no reason to omit them.
Consider this rewrite:
var randmg = (function () {
var img = [
'banner1.png',
'banner2.png',
'banner3.png',
'banner4.png'
];
return function () {
return img[ Math.floor( Math.random() * img.length ) ];
};
})();
