Sorry for by bad english.

Oh! Just fill the color by scanning the barcode. Scanning 1 time, fill the color in the top of image. Second time, second image. So I need to count with user click or scanning time. Thank you so much!

I try to replace this. The loading dissappear but it only runs

if (number==1){
checkcolor();
alert('number1');
}

but does not run
if (number==2){
checkcolor();
alert('number1');
}
.. Thank you so much!

here is the JS Code

var number=localStorage.getItem("number");

if (number==1){
checkcolor();
alert('number1');

}

if (number==2){
checkcolor1();
alert('number2');

}
