请划过或点击下面带框的文本
看我这里一个DIV
提示在我的下面出现
提示在左边出现
提示出现2秒后会自动消失
提示可以有关闭按钮
不同担心页面放大缩小会位置会偏移哦
优点
- 1:兼容 各种浏览器
- 2:自己定义TIPS样式(颜色),CSS3渐进增强
- 3:多方向弹出提示
- 4:纯CSS+javascript(不包含任何图片)
- 5:体积超级小 CSS+js = 3k
参数配置
- ljtips(object).show(JSON)
- object: DOM对象ID(test1), DOM对象
-
json:{ content:提示的消息内容(必须), p:提示框位置(可选值top left bottom right),默认为right(可选), closeBtn:是否有关闭按钮(true false) 默认值(false)(可选), time:多少毫秒提示框消失(可选) }
使用说明
- 主要方法 .show(); .hide();.clear(); 一般你只需要使用show,hide;
- 使用1
- 首先实例化一个ljtips(var tips=ljtips('test1')); 然后使用tips.show(JSON)
- 使用2
- 在行内调用提示框"<div onclick=" ljtips(this).show(JSON); "></div>"
- 使用3
- 在JS里调用document.getElementById("test6").onmouseover = function(){ljtips(this).show({content:"这个框你关不掉了吧!没有关闭按钮!",p:'right'})};
var test1 = ljtips('test1');
document.getElementById("test1").onmouseover = function(){test1.show({content:"鼠标划过时候的TIPS...
兼容主流浏览器 IE 6 7 8 chorme Firefox Opera Safari"})};
document.getElementById("test1").onmouseout = function(){test1.hide();};
document.getElementById("test2").onfocus = function(){ljtips(this).show({content:"这个提示会在
input的上方!有个关闭按钮哦",p:'top',closeBtn:true})};
document.getElementById("test3").onmouseover = function(){ljtips(this).show({content:"我在下面出现了!不要认为会用到图片哦!",p:'bottom',closeBtn:true})};
document.getElementById("test4").onmouseover = function(){ljtips(this).show({content:"我可以在4个方向上",p:'left',closeBtn:true})};
document.getElementById("test5").onmouseover = function(){ljtips(this).show({content:"提示出现2秒后会自动消失",p:'bottom',time:2000})};
document.getElementById("test6").onmouseover = function(){ljtips(this).show({content:"这个框你关不掉了吧!没有关闭按钮!",p:'right'})};
document.getElementById("test7").onmouseover = function(){ljtips(this).show({content:"您可以放大或者缩小浏览器窗口!
他会跟随这个绝对位置,不会有丝毫偏差。",p:'right',closeBtn:true})};
