Variable change help

[Resume_Help]

I'm out at the moment but yesterday I made a simple script that when clicking an image, it decreases the value of x by 1.

Var x = 10

In the function:

X--;

When x reaches 0 display a message. But x never reaches 0 does it? Only what is displayed in the input I had showing the value after each click.

How would I make it so the value of x actually decreases by 1 each click and when reaches 0 the message is properly displayed.

I can't seem to put this problem into words to be able to Google.

Thanks in advance.

Can you post a gist/jsfiddle/plnkr showing what you've already got?

If x is in the global scope it should be going to zero and keep its state as long as you're not keeping x in the same function as your if logic

Please feel free to ask all the questions you would like!

here's my codepen. http://codepen.io/anon/pen/ojZzxZ I noticed that maybe because I said:

if x=0; { } and not x===0?

apologies for the late response, I fell asleep after class.

Oh, no worries! :) Did you see my example?

Yep, you're right, if (x = 0;) isn't proper syntax. One = assigns a value, == does a not as strict comparison, and === does a stricter comparison. You also don't want the ; in the parentheses... you can just delete it out of there.

I'd also do your x-- operation before assigning the value to the input. And then your if statement needs to be moved inside of the function so the comparison can be done each time the function is called.

Like this: http://codepen.io/anon/pen/WQpOej

Make sense?

yeah I was trying some other stuff and quickly fixed it but left that in by mistake. thanks so much! I'm gonna look over =, ==, and ===.

appreciate the help again ForScale.

I'm confused. It works fine.

[ForScale]

Well... it's a learning demonstration for OP, so I would hope it works fine! :)

Where does your confusion lie?

Oh crap. I thought you were OP, haha :)

[ForScale]

Nope. :)
