用JavaScript显示和隐藏浏览器聊天框 [英] Show and hide a browser chat box with JavaScript
问题描述
.chat_txt
或时,不执行该功能。 chat_new_input
是否可以这样做?
// JavaScript显示/隐藏函数
$('。hidden_box')。live(click,function(){showChat(this);});
$('。active_box')。live(click,function(){hideChat(this);});
$('。chat_txt')。click(function(event){
event.preventDefault();
});
以下是DIV的语法:
< div id =chat_system_msg_lpclass =chat_box clickable_box hidden_box>
< div id =chat_system_msg_nickclass =chat_name> system_msg< / div>
< ul id =chat_system_msg_txtclass =chat_txt>
< li id =46>嗨访客。我们建议您以
的顺序登录/注册,以获得Live-Pin< / li>的所有优势。
< / ul>
< form class =chat_new_messagename =new_msg>
< input type =textplaceholder =输入您的消息...
class =chat_new_input>
< / form>
< / div>
使用
$ b $($ {code $ c'$'''''''')('click','.hidden_box:not(.chat_box)',function(){showChat(this);});
如果您使用的是jQuery 1.7+。旧的jQuery:
$('body')。delegate('。hidden_box:not(.chat_box)','click' ,function(){showChat(this);});
同样的另一个。
编辑—我应该进一步解释 .live()
API是一个坏主意,从1.4左右的 .delegate()
函数绝对是首选。您仍然可以使用相同的选择器live,但除非您使用的是旧版本的jQuery,否则不要使用。
I am making a browser chat window in Javascript. I want to execute the function that shows and hides the chat when you click the chatbar, but not execute the function when you click on .chat_txt
or .chat_new_input
Is it possible to do this?
//JavaScript Show/Hide Function
$('.hidden_box').live("click", function(){ showChat(this); });
$('.active_box').live("click", function(){ hideChat(this); });
$('.chat_txt').click(function(event) {
event.preventDefault();
});
Here is the syntax for the DIV:
<div id="chat_system_msg_lp" class="chat_box clickable_box hidden_box">
<div id="chat_system_msg_nick" class="chat_name">system_msg</div>
<ul id="chat_system_msg_txt" class="chat_txt">
<li id="46">Hi visitor. We suggest you to sign in/sign up in order
to have all the benefits from Live-Pin </li>
</ul>
<form class="chat_new_message" name="new_msg">
<input type="text" placeholder="Enter your message..."
class="chat_new_input">
</form>
</div>
Use
$('body').on('click', '.hidden_box:not(.chat_box)', function() { showChat(this); });
if you're on jQuery 1.7+. Older jQuery:
$('body').delegate('.hidden_box:not(.chat_box)', 'click', function() { showChat(this); });
Similarly of course for the other one.
edit — I should have explained further. The .live()
API was kind-of a bad idea, and since around 1.4 the .delegate()
function was definitely preferred. You could still do it with "live" using the same selector, but don't unless you're on a really old version of jQuery.
