我有一个这样的php条件:
<?php
if($numResults > 0)
{ ?>
<button id="unfollow" class="button"> unfollow </button>
<?php }
else
{ ?>
<button id="follow" class="button"> follow </button>
<?php } ?>
但是如果条件转到"else 语句",我想要一个 jquery 事件处理程序,以便当用户单击"关注"时,按钮淡出,"取消关注"淡入
我试过这个,但它只会淡出
"关注"按钮,而不会淡出"取消关注"按钮$('#follow').click(function()
{
$("#follow").fadeOut("slow");
$("#unfollow").fadeIn("slow");
});
有什么建议吗?
<!-- Unfollow button -->
<button id="unfollow"
style="display:<?php echo ( $numResults > 0 ? 'none' : 'block' ); ?>"
class="button">Unfollow</button>
<!-- Follow Button -->
<button id="follow"
style="display:<?php echo ( $numResults > 0 ? 'block' : 'none' ); ?>"
class="button">Follow</button>
你应该把它们都放在页面上,其中一个最初淡出。它在这里工作。http://jsfiddle.net/TzkGT/
<button id="follow" class="button"> follow </button>
<button id="unfollow" class="button" style="display: none;"> unfollow </button>
$('.button').click(function(){
$("#follow").fadeToggle("slow");
$("#unfollow").fadeToggle("slow");
});
$('#follow').click(function()
{
$("#follow").fadeOut("slow",function(){
$("#follow").text("unfollow").fadeIn("slow");
});
});
试试这个
<?php
if($numResults > 0)
{ ?>
<button id="unfollow" class="button"> unfollow </button>
<?php }
else
{ ?>
<button id="follow" class="button"> follow </button>
<button id="unfollow" class="button"> unfollow </button>
<style>
#unfollow { display:none;}
</style>
<?php } ?>
Js
$('#follow').click(function()
{
$("#follow").fadeOut("slow");
$("#unfollow").css("display","block");
$("#unfollow").fadeIn("slow"); // this may not require if you don't want effect
});
