variable inside another variable

Question

hi there i wanted to put this:

document.write("y = " + i);

inside another variable, like this:

s=s+"\"y = \" \+ i";

but now, i variable is not variable, just a plain text.

how can i fix this? output would be

document.getElementById("output").innerHTML=s;

thank you

Answer 1

You do not pass to s string a variable - just text i . Try with:

s=s+"y = " + i;

You can also convert it to:

s += "y = " + i;
