Prototype startsWith OR

Question

Hi Guys,

I am trying to use Prototype and startsWith but I want to check a number of values and little confused how to do this.

Basically have this code:

if(Category.startsWith("[Test1] " || "Test " || "Test2 ")) { some stuff }

It doesn't appear to be working and just wondering what I am doing wrong ?

Answer 1

You need to do them individually:

if(Category.startsWith("[Test1] ")
   || Category.startsWith("Test ")
   || Category.startsWith("Test2 ")) {
    // some stuff
}

In JavaScript, the expression

"[Test1] " || "Test " || "Test 2 "

...evaluates to "[Test1] ", because || returns the first "truthy" operand.

Answer 2

if(Category.startsWith("[Test1] ")
    ||Category.startsWith("Test ")
    ||Category.startsWith("Test2 ")) 
{ 
    //some stuff
}
