I am new to Javascript and am just playing around trying to print a simple for loop to the HTML.
HTML:
<div id="hello"</div>
JS :
var text="";
for (var i=0;i<10;i++) {
document.getElementById("hello").innerHTML=text+i;
}
My problem is that this code only outputs the last iteration '9', and not '0123456789' which is what I want.
Now if i do document.write
it prints out the numbers fine but I heard this is bad practice so I just want to do it the correct way.
Thanks
It would be better to build your text content first and insert it into HTML element once (to save some time):
var text="";
for (var i=0;i<10;i++) {
text += i;
}
document.getElementById("hello").innerHTML = text;
You should use the addition assignment operator +=
that adds a value to a variable, so you're just missing +
before =
in :
document.getElementById("hello").innerHTML += text+i;
NOTE : Use textContent
instead of innerHTML
because you're appending just a text, check example bellow.
var text=""; for (var i=0;i<10;i++) { document.getElementById("hello").textContent += text+i; }
<div id="hello"></div>
