我试图根据“full_day”的值隐藏div类“hideme”如果“full_day”的值= 1,那么div类“hide me”必须向下滑动,如果不是,那么div类hideme一定不能可见的。我究竟做错了什么

(我只使用了这部分: hideme: ("Hello Hideme") 作为一个例子来使用 - 及时这将被其他输入字段替换,例如复选框和单选按钮)

.keyup 也可以,如果寻找整数删除引号

<div id="hideme">
 Hello Hideme
</div>

<input type='text' id="full_day"/>



$("#full_day").change(function(){

    if ($('#full_day').val() == 1) {   
        $("#hideme").hide("fast"); //Slide Down Effect
    }
    else {
        $("#hideme").show("fast");    //Slide Up Effect
    }
});

使用keyup事件而不是更改

$(document).ready(function(){
    $("#full_day").keyup(function(){
        if ($(this).val() == "1" ) {
            $("#hideme").slideDown("fast"); //Slide Down Effect
        } else {
            $("#hideme").slideUp("fast");    //Slide Up Effect
        }
    });
});
