Question

我有一个使用php生成内容的表，该表调用＆＃34; tab1＆＃34;并且有一个名为Id的搜索按钮，带有＆＃34; cmdsearch＆＃34;。点击搜索后，我的内容似乎无法隐藏。我的代码到目前为止

$(document).ready(function() {

    $( "#datepicker" ).hide();
    $( "#datepicker2" ).hide();
    $( "#datepicker" ).datepicker({dateFormat: 'yy/mm/dd'});
    $( "#datepicker2" ).datepicker({dateFormat: 'yy/mm/dd'});
    $("#category").on('change',function(){
        if($("#category").val() == 'ORIGINAL_DEADLINE'){
        $( "#datepicker" ).show();
        $( "#datepicker2" ).show();
         $( "#datepicker2" ).show();

             }else{
               $( "#datepicker" ).hide();
               $( "#datepicker2" ).hide();
     }      
    $("#cmdsearch").click(function(){

        $("#tab1").hide();
    });
});
});

这是我的HTML代码

 <?php  
    // session_start();  

    // if (!isset($_SESSION['username'])) {  
        // header("Location: login.php");  
        // exit;  
    // }
// $username=$_SESSION['username'];

 ?>

您在更改事件处理程序中注册了click事件侦听器，因此除非您更改#category的值，否则不会添加单击处理程序。此外，它有可能会添加多个点击处理程序（每次更改category的值时都有1个新处理程序）

$(document).ready(function () {

    $("#datepicker").hide();
    $("#datepicker2").hide();
    $("#datepicker").datepicker({
        dateFormat: 'yy/mm/dd'
    });
    $("#datepicker2").datepicker({
        dateFormat: 'yy/mm/dd'
    });
    $("#category").on('change', function () {
        if ($("#category").val() == 'ORIGINAL_DEADLINE') {
            $("#datepicker").show();
            $("#datepicker2").show();
            $("#datepicker2").show();

        } else {
            $("#datepicker").hide();
            $("#datepicker2").hide();
        }
    });
    //should be outside of the change event hanlder
    $("#cmdsearch").click(function (e) {
        e.preventDefault();//prevent the form submit since the button is inside a from 
        $("#tab1").hide();
    });
});

但它可以简化为

$(function () {

    var $dtps = $("#datepicker, #datepicker2"); //use a class selector to simplify this

    $dtps.hide().datepicker({
        dateFormat: 'yy/mm/dd'
    });
    $("#category").on('change', function () {
        $dtps.toggle(this.value == 'ORIGINAL_DEADLINE')
    });
    //should be outside of the change event hanlder
    $("#cmdsearch").click(function (e) {
        e.preventDefault();//prevent the form submit since the button is inside a from 
        $("#tab1").hide();
    });
});

演示：Fiddle

注意：由于按钮的类型为submit，并且位于表单内，因此单击按钮的默认操作是提交按钮，因为您需要执行自定义操作以通过调用来阻止它event.preventDefault()或将按钮类型更改为button（如<input type="button" id="cmdsearch" name="cmdsearch" value="Search" />）

单击搜索按钮时jquery隐藏div
