Multiple if checks to 1 variable

[Guest]

Is there another way to code this? Comparing a variable (var1) to multiple values.

if(var1 != array[0] && var1 != array[1] && var1 != array[2]) {}

Is there some other way to code that? Like if(var1 != (array[0] && array[1] && array[2]) ) {}

I know that doesn't work, but is there another way to code it?

If you are checking the entire array then you could use....

if(array.indexOf(var1) == -1) {  }

indexOf() checks to see if var1 exists in the array and if it does not it will return -1,   otherwise it returns the index of the array holding the value of var1

Another wonderful leading answer. Wasn't looking for array checking specifically but that works fine just fine.

if( new Array( valueX, valueY, vallueZ ).indexOf( var1 ) > -1 ) { }

Had a feeling so did a test, new Array().indexOf() takes significantly longer then manually doing var1 == var2 || var1 == ... so gonna have to stick with the original for now.

looped 10k times

~25ms: new Array( 1, 2, 3, 4, 5 ).indexOf(3)

~10ms: myArray.indexOf(3)

~1ms: 1== 1||1== 2||1== 3||1== 4||1== 5

But thanks for the info, I enjoy learning new ways to do things.
