Why doesn't jquery fadeIn() work with .html()?
提问by Edward Tanguay
When you click you a checkbox I want the message to fade in slowly.
当您单击一个复选框时，我希望消息慢慢淡入。
Why doesn't .fadeIn() work in this example?
为什么 .fadeIn() 在这个例子中不起作用？

No fadeIn is done because the #message element is visible, hide it, add the content and fade it in:
没有淡入是因为 #message 元素是可见的，隐藏它，添加内容并淡入：
$('#message').hide().html("You clicked on a checkbox.").fadeIn('slow');

after analize this problem, that I have to solve, this is my code, that works to use fadeout, change html and fadein
在分析这个问题之后，我必须解决，这是我的代码，可以使用淡出，更改 html 和淡入淡出
$("#div_big_picture").fadeOut('slow',function(){
$(this).html("<img src='" + str_to_load + "' height='800px' />")
}).fadeIn("slow");

No idea why but I've had trouble chaining this before. You can get the effect you want by using this less elegant code:
不知道为什么，但我之前在链接它时遇到了麻烦。你可以通过使用这个不太优雅的代码来获得你想要的效果：
google.load("jquery", "1.3.2");
//run when page is loaded
google.setOnLoadCallback(function() {
$('.checkboxList .row').css('color','red');
$('.checkboxList input').attr('checked', true);
$('.checkboxList input').bind('click', function() {
$('#message').hide(); //just in case
$('#message').html("You clicked on a checkbox.");
$('#message').fadeIn('slow');
});
});
