傻乎乎的用if嵌套写了一个带有0的 然后翻到最后一页看到别人的有0的 就那么几行 惭愧 都没想到别的方法
function clock(){
var time = new Date();
var altime;
if(time.getHours()<10){
if(time.getMinutes()<10){
if(time.getSeconds()<10){
altime = "0" + time.getHours() + ":" + "0" + time.getMinutes() + ":" + "0" + time.getSeconds();
}else{
altime = "0" + time.getHours() + ":" + "0" + time.getMinutes() + ":" + time.getSeconds();
}
}else {
if(time.getSeconds()<10){
altime = "0" + time.getHours() + ":" + time.getMinutes() + ":" + "0" + time.getSeconds();
}else{
altime = "0" + time.getHours() + ":" + time.getMinutes() + ":" + time.getSeconds();
}
}
}else {
if(time.getMinutes()<10){
if(time.getSeconds()<10){
altime = time.getHours() + ":" + "0" + time.getMinutes() + ":" + "0" + time.getSeconds();
}else{
altime = time.getHours() + ":" + "0" + time.getMinutes() + ":" + time.getSeconds();
}
}else {
if(time.getSeconds()<10){
altime = time.getHours() + ":" + time.getMinutes() + ":" + "0" + time.getSeconds();
}else{
altime = time.getHours() + ":" + time.getMinutes() + ":" + time.getSeconds();
}
}
}
document.getElementById("clock").value = altime;
}
setInterval(clock, 1000);
