jQuery 是否有一个插件可以显示“消息栏”?就像 Twitter 的“密码错误”一样屏幕顶部的栏?

发布于 2024-09-04 15:10:23 字数 337 浏览 9 评论 0原文

Twitter会在屏幕顶部弹出一个消息栏,说“密码错误”,10秒后,它会向上滑动并消失。 Chrome 也使用这种方式显示“是否要保存密码”消息框。

jQuery 已经有一个插件可以做到这一点吗?它也适用于 IE 6 吗?因为通常情况下,相对于视口的显示(使用 position:fixed)在 IE 6 上不起作用。谢谢。

更新:感谢很好的解决方案 - 我故意希望它能够工作(1)即使用户向下滚动页面,它也会显示在窗口屏幕的顶部和(2)该栏可能会选择显示在窗口屏幕的底部(作为一个选项)...如果它可以在 IE 6 上运行,那就更好了...现在可怜的程序员...

Twitter will pop down a message bar at the top of the screen say "Wrong password" and after 10 seconds, it will slide up and disappear. Chrome also shows "Do you want to save the password" message box using such a way.

Does jQuery have a plug in to do that already? Does it also work in IE 6? Because usually, the display of relative to the viewport (using position: fixed) will not work on IE 6. thanks.

Update: thanks for the nice solutions -- I deliberately wanted it to work (1) even when the user has scrolled down the page, that it will show at the top of the window screen and (2) the bar might be chosen to display at the bottom of window screen instead (as an option)... and if it works on IE 6 then it is even better... poor programmers nowadays...

您只需几行代码即可完成此操作,如下所示:

​​​​function topBar(​​​message) {
  $("<div />", { 'class': 'topbar', text: message }).hide().prependTo("body")
      .slideDown('fast').delay(10000).slideUp(function() { $(this).remove(); });
}

然后只需为您使用的类提供一些样式,例如:

.topbar { 
    background: #990000; 
    border-bottom: solid 2px #EEE; 
    padding: 3px 0; 
    text-align: center; 
    color: white;
}​

您可以在此处查看工作演示,根据需要进行调整:) 这会动态创建一个

,将其添加到正文的顶部,因此没有时髦的定位不用担心,这在 IE6 中应该没问题。完成后,它将向上滑动并删除它创建的

进行清理。无论您需要什么,您都可以添加点击处理程序以立即将其删除等。

You can do this with just a few lines of code, like this:

​​​​function topBar(​​​message) {
  $("<div />", { 'class': 'topbar', text: message }).hide().prependTo("body")
      .slideDown('fast').delay(10000).slideUp(function() { $(this).remove(); });
}

Then just give the class you use some styling, for example:

.topbar { 
    background: #990000; 
    border-bottom: solid 2px #EEE; 
    padding: 3px 0; 
    text-align: center; 
    color: white;
}​

You can view a working demo here, tweak as needed :) This creates a <div> on the fly, adds it to the top of the body, so no funky positioning to worry about, this should be just fine in IE6. When it's finished it'll slideUp and remove the <div> it created to cleanup. You can add a click handler to remove it instantly, etc, whatever your needs are.

好吧,我尝试了一下,想出了这个不错的功能:

[ http://jsfiddle.net/2arVf/< 上的实时示例/a> ]

//
// Usage: sendMessage(message, yes_text, no_text, class_to_style, callback_yes, callback_no)  -- for yes/no
//    or: sendMessage(message, class_to_style[, timeout])  -- informative with optional auto-hide after timeout
//

var sendMessage = function(str,yes,no,my_class,callback_yes,callback_no) {

    clearMessageTimeout(); // clear the timeout so it doesn't accidentaly slide up

    if (typeof no == 'string') {   // check if this is a yes/no message

        $message.slideUp(0, function() {  // slide up if not already
            // scroll to the top so the user gets to see the message             
            $("html").animate({'scrollTop': 0}, 'fast', function() {    // then
                $message
                .unbind('mouseout').attr('class','')      // kill old classes
                .addClass(my_class)    // add our class styling
                .html([ str, '<br />', // create an array to add our
                                       // two handlers with #yes and #no IDs
                        '<button id="yes">', yes ,'</button>',
                        '<button id="no">' , no  ,'</button>'
                      ].join('')       // join the array and
                     )                 // insert message
                .slideDown(1000)       // slide the message down
                .find('#yes,#no')      // find #yes and #no
                .click(function() {    // add click handler to #yes and #no                            
                    var answer=$(this).attr('id');           // should be 'yes' or 'no'
                    $message.slideUp(1000, function() {      // slide up and
                        $("html").animate({'scrollTop': 0},  // scroll to top again and
                            eval('callback_' + answer)       // call our callback
                        );
                    });
                });     
            });        
        });

    } else {                  

        $message
            .unbind('mouseout')                // unbind previous mouseout
            .attr('class','')                  // kill old classes
            .addClass(yes)                     // add our class
            .html(str)                         // insert our message
            .slideDown(1000, function() {      // slide down the message
            $message.mouseout(function() {     // bind mouse out
                setMessageTimeout(function() { // with a timeout if the pointer comes back
                    $message.slideUp(1000);    // to slide back up
                }, 1000);                      // after 1 second
            });                           
        });

        if (typeof no == 'number') {       // if a timeout is specified
            setMessageTimeout(function() { // then it sets it
                $message.slideUp(1000);    // to slide up by itself
            }, no);                        // after x milliseconds
        }
    }
}

// Initialize messenger

$("<div></div>").prependTo('body').attr('id','message');

var $message = $("#message")
    .mousemove(clearMessageTimeout),
    message_timeout;

function setMessageTimeout(callback, time) {
    clearTimeout(message_timeout);
    message_timeout = setTimeout(callback, time);
}

function clearMessageTimeout() {
    clearTimeout(message_timeout);
}

示例:

$(".invoke_message").click(function(e) {

    sendMessage(

        [ 'Here I am, a message..',
          'I can be multiline',
          '<strong>and have any html</strong>',,
          'Do you like me?'
        ].join('<br />'),

        'Yeap','Nope',  // yes and no text

        'normal',       // normal class

        function() {    // yes callback
            sendMessage('Thank you. I\'ll be gone in 3 secs', 'happy', 3000);
        },

        function() {    // no callback
            sendMessage('OK, have it your way then. You need to mouseout me to make me leave', 'sad');
        }

    );

    return false;
});

CSS:

body {
    padding:0;
    margin:0;
}
strong {
    font-weight:bold;
}
#message {
    color:#fff;
    text-align:center;
}
.normal {
    background-color:#888;
}
.happy {
    background-color:#cc2;
}
.sad {
    background-color:#b44;
}

HTML:

<p>I'm the main page. I'll do some space if there is a message</p>
<p><a class="invoke_message" href="#">Click me</a></p>
.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br /><p><a class="invoke_message" href="#">Click me too</a></p>

Well I played around and came up with this nice function:

[ live example on http://jsfiddle.net/2arVf/ ]

//
// Usage: sendMessage(message, yes_text, no_text, class_to_style, callback_yes, callback_no)  -- for yes/no
//    or: sendMessage(message, class_to_style[, timeout])  -- informative with optional auto-hide after timeout
//

var sendMessage = function(str,yes,no,my_class,callback_yes,callback_no) {

    clearMessageTimeout(); // clear the timeout so it doesn't accidentaly slide up

    if (typeof no == 'string') {   // check if this is a yes/no message

        $message.slideUp(0, function() {  // slide up if not already
            // scroll to the top so the user gets to see the message             
            $("html").animate({'scrollTop': 0}, 'fast', function() {    // then
                $message
                .unbind('mouseout').attr('class','')      // kill old classes
                .addClass(my_class)    // add our class styling
                .html([ str, '<br />', // create an array to add our
                                       // two handlers with #yes and #no IDs
                        '<button id="yes">', yes ,'</button>',
                        '<button id="no">' , no  ,'</button>'
                      ].join('')       // join the array and
                     )                 // insert message
                .slideDown(1000)       // slide the message down
                .find('#yes,#no')      // find #yes and #no
                .click(function() {    // add click handler to #yes and #no                            
                    var answer=$(this).attr('id');           // should be 'yes' or 'no'
                    $message.slideUp(1000, function() {      // slide up and
                        $("html").animate({'scrollTop': 0},  // scroll to top again and
                            eval('callback_' + answer)       // call our callback
                        );
                    });
                });     
            });        
        });

    } else {                  

        $message
