I'm creating simple calculator but I have problem..

Question

I've done html, css,& js work... but I can't evaluate the numbers .
function e () {
var evalo = eval (document.fre.text.value)
document.fre.text.value = ; // help me
}

Answer 1

document.fre.text.value = evalo;

Answer 2

it's better if you do:
try {
var a = eval(b);
}
catch (err) {
alert(err);
}
so errors don't mess up the screen on mobile phones.

Answer 3

you haven't made it open for public yet. 😕

Answer 4

Thank you. I've done it last night
