Javascript 中,数字 0 为假,非0 均为真 在条件判断运算 == 中的转换规则是这样的: 如果比较的两者中有布尔值(Boolean),会把 Boolean 先转换为对应的 Number,即 0 和 1,然后进行比较. 如果比较的双方中有一方为 Number,一方为 String时,会把 String 通过 Number() 方法转换为数字,然后进行比较. 如果比较的双方中有一方为 Boolean,一方为 String时,则会将空字符串""转换为 false,除此外的一切字符…

1. 条件测试的表达式 1. [ expression ]  :注意这个中括号的前后都有一个空格 2. [[ expression ]] 3. test expression 2.条件判断的类型 1. 整数测试 2. 字符测试 3. 文件测试 3. 整数比较 -eq:测试整数是否相等 还有一些其它操作如下. 4. 命令的逻辑关系 逻辑与 &&, 第一个为假,第二个不会判断 逻辑或 ||,第一个为真,第二个不会判断 如果用户user20不存在,则添加一个user20.前面为真,后面就执行us…
