代码
 应该可以加个form表单，提交的服务器的数据input的多选框value值是使用“，”隔开的字符串
<script type="text/javascript">
function ChooseAll(sel, check) {
    var objtb = document.getElementById(sel);
    var num = objtb.getElementsByTagName("input");
    var check = document.getElementById(check);
    for (i = 0; i < num.length-1; i++) {
        if (num[i].tagName == "INPUT") {
   alert(num[i].value);
            if (check.checked == true)
            { num[i].checked = true; }
            else { num[i].checked = false; }
        }
    }
}
</script>
