懸停時顯示div出現問題

Question

我在懸停時顯示div時遇到問題。

當我將鼠標懸停在div元素A ，將按照我的期望顯示div元素B 但是，當鼠標指針離開div元素A ， div元素B不會消失。

  $('.display_cal').hover(function () { $('.calender_category_div').css("display" , "block"); }); 

  .datespan{ display: block; } .calender_category_div{ position: absolute; top: 40%; left: 50%; z-index: 1050; background: #FFFFFF; padding: 10px 20px; display: none; } .calender_category_div ul{ padding: 0; } .calender_category_div ul a { color: #428bca; text-decoration: none; } .calender_category_div ul a:hover { color: #428bca; } .calender_category_div ul { color: #428bca; list-style-type: none; }

我缺少什么？

Answer 1

通過jQuery或CSS有兩個解決方案

更新 ：將p標簽更改為div

css的懸停效果：

.display_cal:hover  >.calender_category_div{
  display:block;
  }

它會為您提供toggle效果。

或使用jQuery

$(document).ready(function (){
  $('.display_cal').mouseover(function(){
    $('.calender_category_div').show();
    })
  $('.display_cal').mouseleave(function(){
    $('.calender_category_div').hide();
    })

  })

更新的示例：

 .datespan{ display: block; } .calender_category_div{ position: absolute; top:5px; right:-10; z-index: 1050; background: transparent; padding: 10px 20px; display: none; } .display_cal:hover >.calender_category_div{ display:block; } .calender_category_div ul{ padding: 0; } .calender_category_div ul a { color: #428bca; text-decoration: none; } .calender_category_div ul a:hover { color: #428bca; } .calender_category_div ul { color: #428bca; list-style-type: none; }

Answer 2

您需要在p內添加calender_category_div 。 將p替換為div標簽。 然后在css幫助下它將起作用。 無需編寫jquery

 .datespan{ display: block; } .calender_category_div{ background: #FFFFFF; padding: 10px 20px; display: none; } .calender_category_div ul{ padding: 0; } .calender_category_div ul a { color: #428bca; text-decoration: none; } .calender_category_div ul a:hover { color: #428bca; } .calender_category_div ul { color: #428bca; list-style-type: none; } .display_cal:hover .calender_category_div{display:block} 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js" type="text/javascript"></script> <div style="float: right;color: #17469e;" class="display_cal">12 october 2016 <div class="calender_category_div" > <ul> <a id="fl_ical" href="http://addtocalendar.com/atc/ical?f=m&e[0][date_start]=2016-12-02%2009%3A00%3A00&e[0][date_end]=2016-12-02%2018%3A30%3A00&e[0][timezone]=Pacific%2FPitcairn&e[0][title]=StartupBridgeIndia&e[0][description]=StartupBridge%20India%20conference%20aims%20to%20foster%20cross-border%20partnerships%20%26%20collaboration%2C%20and%20open%20up%20investment%2Facquisition%20opportunities%20for%20US%20Tech%20companies%20in%20India.%20The%20event%20is%20organized%20by%20TiE%20Silicon%20Valley%2C%20iSPIRT%2C%20and%20Stanford%20Center%20for%20International%20Development%20(SCID)%20and%20will%20be%20held%20on%20December%202nd%202016%20at%20Stanford%20University.&e[0][location]=SIEPR%2C%20Stanford%2C%20CA&e[0][organizer]=iSPIRT%2C%20TIE%20%26%20SIEPR&e[0][organizer_email]=rajan%40ispirt.in&e[0][privacy]=public" target="_blank"><li>iCalendar</li></a> <a id="fl_google" href="http://addtocalendar.com/atc/google?f=m&e[0][date_start]=2016-12-02%2009%3A00%3A00&e[0][date_end]=2016-12-02%2018%3A30%3A00&e[0][timezone]=Pacific%2FPitcairn&e[0][title]=StartupBridgeIndia&e[0][description]=StartupBridge%20India%20conference%20aims%20to%20foster%20cross-border%20partnerships%20%26%20collaboration%2C%20and%20open%20up%20investment%2Facquisition%20opportunities%20for%20US%20Tech%20companies%20in%20India.%20The%20event%20is%20organized%20by%20TiE%20Silicon%20Valley%2C%20iSPIRT%2C%20and%20Stanford%20Center%20for%20International%20Development%20(SCID)%20and%20will%20be%20held%20on%20December%202nd%202016%20at%20Stanford%20University.&e[0][location]=SIEPR%2C%20Stanford%2C%20CA&e[0][organizer]=iSPIRT%2C%20TIE%20%26%20SIEPR&e[0][organizer_email]=rajan%40ispirt.in&e[0][privacy]=public" target="_blank"><li>Google Calendar</li></a> </ul> </div> </div> 

Answer 3

這是您需要的：

$(".calender_category_div").mouseleave(function(){
    $(".calender_category_div").css("display", "none");
});
