I want to intersperse the second with the first.
For illustration, I will use the simple example below as a basis:
<script>
n = 10;
for ( var i = 0; i < n; i++){document.body.innerHTML += i;}
for ( var i = 0; i < n; i++){c = String.fromCharCode(i+64);document.body.innerHTML += c;}
</script>
In short, I want to put the second loop inside the first, so that it gets 2 in 1 making it a compact but functional code.
Followed version with question edit :
for(var i=0; i<10; i++){
document.body.innerHTML += i + String.fromCharCode(i+64);
}Gives the same as:
for(var i=0; i<10; i++){
document.body.innerHTML += i;
document.body.innerHTML += String.fromCharCode( i + 64 );
}
If you were to make an array :
Two loops within each other would be better suited to make an array:
for(var i=0; i<10; i++){
for(var j=0; j<10; j++){
document.body.innerHTML += i + String.fromCharCode( j + 64 ) + ' ';
}
document.body.innerHTML += '<br>'; // quebra de linha pra facilitar a leitura
}
If you were to do sequential operations :
for(var i=0;i<20;i++){document.body.innerHTML+=i<10?i:String.fromCharCode(i+54);}That is, instead of two loops from 0 to 9, we have a 0 to 19.
If it is 0 to 9, the% ternary% will add i<10? to the page.
else, it will add i . Note that I changed to 54, to discount the difference of the position of the loop. If you do not want String.fromCharCode(i+54) , just use 55;
That is, instead of two loops from 0 to 9, we have a 0 to 19.
Just to stay more didactic, there follows a version of the first simpler version to read, but that works in exactly the same way:
for(var i = 0; i < 20; i++ ) {
if( i < 10 ) {
// Aqui faz a parte do 1o loop
document.body.innerHTML += i;
} else {
// Aqui faz a parte do 2o loop
document.body.innerHTML += String.fromCharCode( i - 10 + 64 );
}
} To understand the @ that is "hidden" in the first code, just see this question:
The language is different, but the operation of if is the same.
