function AdjustScale(){
scaleX = window.innerWidth / 1024;
scaleY = window.innerHeight / 768;
element = document.getElementById("IFM");
element.style.transform = "scale(" + scaleX + ", " + scaleY + ")";
}
I'm facing an issue with this piece of code. I'm unable to use variables in the scale function!
Any suggestions for resolving this problem?
One thing to note is that JavaScript does not support inline string variables. The only way to handle strings is by concatenating them:
Z.style.transform = "scale("+X+", "+Y+")";
When performing this concatenation, the numbers will be automatically converted into strings.
While there are options like using a custom sprintf-like format or replace methods, most of the time simple concatenation with + is sufficient and easier to implement.
To create the desired string, one can either concatenate using concats / plus or utilize String.prototype.replace.
Z.style.transform = "scale(" + X + "," + Y + ")";
Alternatively, a helper function can be used:
String.prototype.sFormat = function _simpleFormat( map ) {
var myString = this.toString(),
args = map instanceof Array ? map : Array.prototype.slice.call( arguments );
while( ~myString.indexOf( '%r' ) ) {
myString = myString.replace( '%r', args.shift() );
}
return myString;
};
Then proceed with:
Z.style.transform = "scale(%r, %r)".sFormat(X,Y);
Revise the following line:
Z.style.transform = "scale(" + X +", "+ Y + ")";
Perhaps you could consider using something along the lines of "setTransform(" +X+ "," +Y+ ")";
