如何使用JQuery执行以下操作?
1.将消息插入div,其中id ="message"并使div可见.2.使消息可见3秒钟.3.删除div"message"的内容.4.隐藏div然后在必要时从步骤1开始.
先感谢您.
我是这样做的:
$.msg = function(text, style)
{
style = style || 'notice'; //<== default style if it's not set
//create message and show it
$('<div>')
.attr('class', style)
.html(text)
.fadeIn('fast')
.insertBefore($('#page-content')) //<== wherever you want it to show
.animate({opacity: 1.0}, 3000) //<== wait 3 sec before fading out
.fadeOut('slow', function()
{
$(this).remove();
});
};

你可以这样做:
var $messageDiv = $('#message'); // get the reference of the div
$messageDiv.show().html('message here'); // show and set the message
setTimeout(function(){ $messageDiv.hide().html('');}, 3000); // 3 seconds later, hide
// and clear the message
