1、js代碼部分

復制代碼 代碼如下:

<script type="text/javascript">
$(function() {

function albumName() {
var text = $("#album_name").val();
var counter = text.length;
$("#numtj var").text(counter);
$(document).keyup(function() {
var text = $("#album_name").val();
var counter = text.length;
$("#name_word").text(counter);
});
}
});
</script>

復制代碼 代碼如下:

<input type="text" maxlength="30">
<span><span>0</span>/30</span>
