Answer 1

You don't necessarily need jQuery.(你不一定需要jQuery。)

JavaScript alone will do this.(只有JavaScript才能做到这一点。) var a = 2; var b = 3; var c = ((a < b) ? 'minor' : 'major'); The c variable will be minor if the value is true , and major if the value is false .(该c变量将是minor ，如果值是true ，且major如果值是false 。) This is known as a Conditional (ternary) Operator.(这被称为条件（三元）运算符。) https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Operators/Conditional_Operator(https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Operators/Conditional_Operator)
