[英]How can I adjust the color of an html element based on a certain js value smoothly and efficiently?
[英]How can I change the value of an element smoothly?
這是我的代碼:
$('button').on('click', function(){ $('div').html('<p>something new!</p>').fadeIn(1000); });
div{ border: 1px solid gray; text-align: center; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div> <p>something<p> </div> <br> <button>change div's value</button>
如您所見,我使用了fadeIn()
來使替換值操作變得平穩。 但是更換仍然很快發生。 我如何對其施加效果?
您可以在更改html
之前添加.hide():
$('button').on('click', function(){ $('.d').hide().html('<p>something new!</p>').fadeIn(1000); });
div{ border: 1px solid gray; text-align: center; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="d"> <p>something<p> </div> <br> <button>change div's value</button>
淡入淡出之前,只需將其隱藏即可:
$('div').hide().html('<p>something new!</p>').fadeIn(1000);
像這樣嗎?
$('button').on('click', function(){ var replacingDiv = $('div.replace'); $(replacingDiv).fadeOut(500); setTimeout(function(){ $(replacingDiv).html('changed').fadeIn(1000); }, 500); });
div{ border: 1px solid gray; text-align: center; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="replace"> <p>something<p> </div> <br> <button>change div's value</button>
