1、准备好需要用到的图标。
2、新建html文档。
3、书冲况艳写hmtl代码。
<center>
<a href="javascript:" id="ahover" tooltips="这里是hover的tips">鼠标滑过自动显示</a> <a href="#" id="aclick" tooltips="<img src='a.png'>">点击显示提示信息</a>
</center>
4、书写css代码。
<style>
* { margin: 0; padding: 0; }
body { padding: 200px; font-size: 12px; background-color: #f0f0f0; }
.tooltips { border-width: 1px; border-style: solid; position: absolute; display: none; border-radius: 3px; opacity: 0; filter: alpha( opacity = 0); z-index: 999; }
.tooltips p.content { padding: 5px; }
.tooltips .triangle-front, .tooltips .triangle-back { width: 0; height: 0; overflow: hidden; border-width: 8px; border-style: solid; position: absolute; border-color: transparent; top: 100%; left: 50%; margin-left: -8px; }
.tooltips .triangle-back { margin-top: -1px; }
.yellow { border-color: #c7c08d; background-color: #fffac3; }
.yellow .triangle-front { border-top-color: #c7c08d; }
.yellow .triangle-back { border-top-color: #fffac3; }
a { padding: 5px; margin-right: 20px; border: 1px solid #cc00dd; }
</style>
5、书写并添加js代码。
<script src="jquery-1.10.2.min.js"></script>
<script>
$.fn.extend({
hoverTips : function (){
var self = $(this);
var sw = self.get(0).switch;
if( !sw ) {
sw = true;
var content = self.attr("tooltips");
var htmlDom = $("<div class='tooltips'>")
.addClass("yellow")
.html("<p class='content'>"
+ "<p class='triangle-front'>"
+ "<p class='triangle-back'>");
htmlDom.find("p.content").html( content );
}
self.on("mouseover"毙互,function(){
$("body").append( htmlDom );
var left = self.offset().left - htmlDom.outerWidth()/2 + self.outerWidth()/2;
var top = self.offset().top - htmlDom.outerHeight() - parseInt(htmlDom.find(".triangle-front").css("border-width"));
htmlDom.css({"left":left,"top":top - 10,"display":"block"});
htmlDom.stop().an 良巨 imate({ "top" : top ,"opacity" : 1},300);
});
self.on("mouseout",function(){
var top = parseInt(htmlDom.css("top"));
htmlDom.stop().an imate({ "top" : top - 10 ,"opacity" : 0},300,function(){
htmlDom.remove();
sw = false;
});
});
},
clickTips : function (){
var self = $(this);
var sw = self.get(0).switch;
if( !sw ) {
sw = true;
var content = self.attr("tooltips");
var htmlDom = $("<div class='tooltips'>")
.addClass("yellow")
.html("<p class='content'>"
+ "<p class='triangle-front'>"
+ "<p class='triangle-back'>");
htmlDom.find("p.content").html( content );
}
self.on("click",function(){
$("body").append( htmlDom );
var left = self.offset().left - htmlDom.outerWidth()/2 + self.outerWidth()/2;
var top = self.offset().top - htmlDom.outerHeight() - parseInt(htmlDom.find(".triangle-front").css("border-width"));
htmlDom.css({"left":left,"top":top - 10,"display":"block"});
htmlDom.stop().an imate({ "top" : top ,"opacity" : 1},300, function(){
setTimeout(function(){
htmlDom.stop().an imate({"top":top - 10 ,"opacity" : 0},300,function(){
htmlDom.remove();
sw = false;
})
},2000)
});
})
}
});
$("#ahover").hoverTips();
$("#aclick").clickTips();
</script>
6、代码整体结构。
7、查看效果。
