Display javascript variable in html

Question

I'm trying to display a variable with this code:

HTML:

<div id="MyEdit">Money</div>

JS:

var price1 = 0;
var current_value=document.getElementById("MyEdit").innerHTML;

if (current_value == "msc" or current_value == "phd") {
    price1 = 150;
}
else {
    price1 = 250;
}

document.getElementById("MyEdit").innerHTML = price1;

Any tips as to what I am doing wrong?

It's a var now, and the guy who answered told me to open a new one if it did not do what I needed. :P — Coolcrab

is the var price1 in global scope? does window.price1 contain the value when you access it from the console? — cschuff

Your if is wrong. There is no operator or. In javascript operator or is declared with ||

You can read more for logical operators here.

Try

var price1 = 0;

if ((current_value == "msc") || (current_value == "phd")) {
    price1 = 150;
}
else {
    price1 = 250;
}

Also i suppose that above this block of code you initialize somewhere current_value

price1 should be initialized even with the broken if

@cschuff price1 is initialized to 0. The OP dont gine the declaration of current_value which i suppose is somewhere above with the rest of the code

well, you are right. if setting the innerHTML is executed on the same 'thread' it will break. an uninitialized 'current_value' will not break anything though.
