再说说另外两个亲戚,setTimeout、setInterval 函数,它们也能接受字符串参数或者函数参数。当传递的是字符串参数时,setTimeout、setInterval 会像 eval 那样去处理。同样也需要避免使用这两个函数的时候使用字符串传参数。 eval 函数带来的问题总结如下: 函数变成了字符串,可读性差,存在安全隐患。 函数需要运行编译器,...

setTimeout() 的基本语法: setTimeout(function/code, delay, arg1, arg2, ...); function/code:必需。要执行的函数或一段代码的字符串。推荐使用函数,避免使用字符串形式的代码,因为使用字符串形式的代码会导致性能问题,并且不易调试。 delay:必需。延迟的毫秒数(1秒 = 1000毫秒)。 arg1, arg2, ...:...
