Issues with JavaScript Shopping Cart
This Javascript code seems to have some underlying issue preventing it from functioning correctly. It would be great if we could simplify it as well :)
var computer = new Array();
computer[0] = "10001, Nvidia Geforce GTX 690, 1200";
computer[1] = "10002, Raedon HD 7950, 450";
computer[2] = "20001, Ivy Bridge i7 3770, 400";
computer[3] = "20002, Ivy Bridge i7 3770k, 420";
...
...
</form>
Here are some points to consider in order to possibly resolve the issue:
parseFloat instead of ParseFloat,computer[x/2] which could result in a decimal array index,innerHTML.(This is not the answer you're looking for.)
Let me propose a simplification, although there are a couple of things to keep in mind:
function check() {
setChecks(false);
}
function uncheck() {
setChecks(true);
}
function setChecks(checked) {
var leftSide = document.getElementById('table_container_left');
var inputs = leftSide.getElementsByTagName('input');
var textValue = checked ? "1" : "0";
var x;
for (x = 0; x < inputs.length; x++) {
if (inputs[x].type == 'text') {
inputs[x].value = textValue;
} else {
inputs[x].checked = checked;
}
}
}
You may also want to think about initializing arrays immediately and using objects. Additionally, the object containing the computers should be named appropriately as computers. It's not just one computer, it's multiple computers; plural.
var computers = [
{ id: "10001", name: "Nvidia Geforce GTX 690", price: 1200 },
{ id: "10002", name: "Raedon HD 7950", price: 450 },
// ...
];
When working with arrays, why not fully embrace their potential?
device[0] = [20001, "lorem ipsum dolor"];
device[1] = [20002, "ipsum lorem amet"];
