本文实例讲述了jQuery bt气泡实现悬停显示及移开隐藏功能的方法。分享给大家供大家参考，具体如下：
SEOver","click"],contentSelector:"$(this).next().html()",positions:["left","bottom"],fill:"#FFD97A",strokeWidth: 0,shadow: true,shadowOffsetX: 3,shadowOffsetY: 3,shadowBlur: 8,shadowColor: "rgba(0,.9)",shadowOverlap: false,noShadowOpts: {strokeStyle: "#999",strokeWidth: 2},});
var hideDelayTimer = null;
var hideDelayTimer2 = null;
$("div.bt-content").live("mouSEOver",function(e){
if (hideDelayTimer) clearTimeout(hideDelayTimer);
if (hideDelayTimer2) clearTimeout(hideDelayTimer2);
});
$("div.bt-content").live("mouSEOut",function(e){
if (hideDelayTimer) clearTimeout(hideDelayTimer);
hideDelayTimer2 = setTimeout(function(){
$("div.bt-wrapper").remove();
},100);
});
$("img.eq-message").mouSEOver(function(){
if (hideDelayTimer2) clearTimeout(hideDelayTimer2);
if (hideDelayTimer) clearTimeout(hideDelayTimer);
}).mouSEOut(function(){
hideDelayTimer = setTimeout(function(){
$("div.bt-wrapper").remove();
},100);
});
代码如下:
