Question

I’m trying to compare the value of some data from an ajax request (json) against a predefined number, and then output some HTML as a result.

Basically, if x is > than y, show ‘this’.

I’m saving the bits I need from the ajax request as:

var x = [];
var y = [];
var z = [];

I believe these are arrays (not sure if this has an impact when I get to my problem in a moment?)

Then I’d like to compare x, y and z against some preset numbers and output something as a result. Here’s what I’ve got so far…

if(x > '3') {
    //do some stuff
}
else if(x > '2') {
    //doing something else
}
else if(y > '5') {
    //do this other thing
}
else if(z == '20') {
    //do that
}
else {
    //do the rest
}

This isn’t working because some of the values are double digit numbers, so I think I have to use parseInt, which I’ve tried, like this…

if(parseInt(x, 10) > '3') {
    //do some stuff
}
else if(parseInt(x, 10) > '2') {
    //doing something else
}
else if(parseInt(y, 10) > '5') {
    //do this other thing
}
else if(parseInt(z, 10) == '20') {
    //do that
}
else {
    //do the rest
}

However, this isn’t working but it’s not giving me any errors either. I’m pretty sure a switch statement would be better too but I have a feeling it’s not that which is causing the problem.

I’m a designer struggling to get to grips with jquery so please excuse my naivety, any help greatly appreciated. Thanks in advance.

Answer 1

as you initially said, the problem is that you are comparing an array with a number, compare a array’s index which is numeric to a number..
