美化演示教程简介浏览器自带的alt和title提示太丑了，所以我们需要美化一下，百度有许多，不过对我们这些小白来说很难。第一步放以下js到公用js里面var sweetTitles = { x: 10, y: 20, tipElements: "a,span,img,div ", noTitle: false, init: function() { var b = this.noTitle; $(this.tipElements).each(function() { $(this).mouseover(function(e) { if (b) { isTitle = true } else { isTitle = $.trim(this.title) != '' } if (isTitle) { this.myTitle = this.title; this.title = ""; var a = "<div class='tooltip'><div class='tipsy-arrow tipsy-arrow-n'></div><div class='tipsy-inner'>" + this.myTitle + "</div></div>"; $('body').append(a); $('.tooltip').css({ "top": (e.pageY + 20) + "px", "left": (e.pageX - 20) + "px" }).show('fast') } }).mouseout(function() { if (this.myTitle != null) { this.title = this.myTitle; $('.tooltip').remove() } }).mousemove(function(e) { $('.tooltip').css({ "top": (e.pageY + 20) + "px", "left": (e.pageX - 20) + "px" }) }) }) } }; $(function() { sweetTitles.init() });第二步css也是/*tips*/ .tooltip { font-size:12px; position:absolute; padding:5px; z-index:100000; opacity:.8; font-family:Microsoft Yahei } .tipsy-arrow { position:absolute; width:0; height:0; line-height:0; border:6px dashed #000; top:0; left:20%; margin-left:-5px; border-bottom-style:solid; border-top:0; border-left-color:transparent; border-right-color:transparent } .tipsy-arrow-n { border-bottom-color:#666 } .tipsy-inner { background-color:#666; color:#FFF; max-width:200px; padding:5px 8px 4px 8px; text-align:center; border-radius:3px }
