setTimeout传参，我主要是做一个发送完验证码倒计时的功能，下面贴代码:
var timeout = 60;
function changeSendSmsButtonSecond(buttonId) {
timeout--;
if(timeout <= 0 ){
timeout = 60;
$(buttonId).text("获取验证码")
}else{
$(buttonId).text("重发(" + timeout + ")")
setTimeout(changeSendSmsButtonSecond, 1000,buttonId)
}
}
function changeSendSmsButton(buttonId) {
$(buttonId).text("重发(" + timeout + ")")
setTimeout(changeSendSmsButtonSecond, 1000,buttonId)
}
我用的语法是这样的 setTimeout(function, milliseconds, param1, param2, ...)
Processed:
0.013, SQL:
9
