獲得一個小三角形上垂直標籤效應

Question

這裏是我的 JsFiddle

$(document).ready(function() { 
$('.content #tab1, .content #tab2, .content #tab3, .content #tab4').css('display','none'); 
$('.vertical-tab').click(function() { 
    custom_reset(); 
    $(this).css('background-color','#fff'); 
    var currentId = $(this).attr('id'); 
    $('.content').find("#" + currentId).css('display','block'); 
}); 
}); 
function custom_reset() { 
$('.vertical-tab').css('background-color','#abcdef'); 
$('.content #tab1, .content #tab2, .content #tab3, .content #tab4').css('display','none'); 
} 

在點擊選項卡上，我想一個小左三角形出現在標籤的中心被點擊。我如何得到這種效果。

CSS

//display the div as a triangle 
border-bottom: 10px solid transparent; 
border-top: 10px solid transparent;

width: 0px;

您可以使用

$(this).html("<img class='triangle' src='path/to/triangle.png'>");

Answer 3

<li> 
    <a href="#" class="vertical-tab" id="tab1"></a> 
    <img id="triangle" src="/path"/> 
</li> 

#triangle{ 
    position: absolute; 
    display:none; 
    z-index:1000; 
    margin-top:-60px //as per the position you want to place the image at 
} 

$('.vertical-tab').click(function() { 

    //your code as it is.. 

    var currentId = $(this).attr('id'); 

    $(this).siblings('#triangle').show() //add this statement 

    //your code as it is.. 

}); 

/*add #triangle in function custom_reset*/ 

$('#triangle,.content #tab1, .content #tab2, .content #tab3, .content #tab4').css('display','none');
