Javascript语法

Question

你说怎么办if (A == 0) OR (B == 0)？

Answer 1

只是为了讽刺:

if (A === 0 || B === 0)

Answer 2

if (A == 0 || B == 0) 

要么

if ((A == 0) || (B == 0)) 

查看Wikibooks上的控制结构和操作符

Answer 3

if (  A == 0  ||  B == 0 ) {
}

Answer 4

取决于你是指独家或包容OR :)

包容性OR:

if(A == 0 || B == 0) 
{ 
}

独家OR:

if(A == 0 && B != 0 || A != 0 && B == 0) 
{ 
}
