在JavaScript中,逻辑 AND 运算符用双和号(&&)表示

1 var bTrue = true;
2 var bFalse = false;
3 var bResult = bTrue && bFalse;

  下面的真值表描述了逻辑AND运算符的行为:

运算数 1 运算数 2 结果
true true true
true false false
false true false
false false false

  

  需要说明的是:逻辑AND运算的运算数可以是任何类型的,不止是Boolean值,如果某个运算数不是原始的Boolean型值,逻辑AND运算并不一定返回Boolean值

逻辑AND运算符的运算行为如下:

  1. 如果一个运算数是对象,另一个是 Boolean 值,返回该对象。
  2. 如果两个运算数都是对象,返回第二个对象。
  3. 如果某个运算数是 null,返回 null。
  4. 如果某个运算数是 NaN,返回 NaN。
  5. 如果某个运算数是 undefined,发生错误。
  6. 如果两个运算数都是boolean类型,则返回boolean值

  与Java中的逻辑AND运算相似,JavaScript 中的逻辑AND运算也是简便运算,即如果第一个运算数决定了结果,就不再计算第二个运算数。对于逻辑AND运算来说,如果第一个运算数是false,那么无论第二个运算数的值是什么,结果都不可能等于true。
  考虑下面的例子:

1 var bTrue = true;
2 var bResult = (bTrue && bUnknown); //发生错误
3 alert(bResult); //这一行不会执行

  这段代码在进行逻辑 AND 运算时将引发错误,因为变量 bUnknown 是未定义的。变量 bTrue 的值为 true,因为逻辑 AND 运算将继续计算变量 bUnknown。这样做就会引发错误,因为 bUnknown 的值是 undefined,不能用于逻辑 AND 运算。
    如果修改这个例子,把第一个数设为 false,那么就不会发生错误:

1 var bTrue = false;
2 var bResult = (bTrue && bUnknown); //不会发生错误
3 alert("bTrue && bUnknown的结果是:"+(bResult));//输出 "false"

  在这段代码中,脚本将输出逻辑AND运算返回的值,即字符串"false"。即使变量 bUnknown 的值为 undefined,它也不会被计算,因为第一个运算数的值是 false。

运行结果:
