jquery - 如何使用 jQuery 设置输入字段的值

Question

我想在输入字段中显示当前时间。我使用了 id local-time。但在输入字段中，没有显示当前时间。

Current Time : <input type="text" id = "local-time" value= ""/>

<script>
setInterval(function() {
var local = new Date();
var localdatetime = local.getHours() + ":" + pad(local.getMinutes()) + ":" + 
pad(local.getSeconds());

$('#local-time').html(localdatetime);
}, 1000);

function pad(t) {
var st = "" + t;

while (st.length < 2)
st = "0" + st;

return st;  
}
</script>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

只需编辑脚本:将 html 更改为 val

<script>
setInterval(function() {
var local = new Date();
var localdatetime = local.getHours() + ":" + pad(local.getMinutes()) + ":" + 
pad(local.getSeconds());

$('#local-time').val(localdatetime);
}, 1000);

function pad(t) {
var st = "" + t;

while (st.length < 2)
st = "0" + st;

return st;  
}
</script>
