jQuery bt气泡实现悬停显示及移开隐藏功能的方法
本文实例讲述了jQuerybt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：
jQuery.bt.options.closeWhenOthersOpen=true;
$("img.eq-message").bt({
trigger:["mouseover","click"],
contentSelector:"$(this).next().html()",
positions:["left","bottom"],
fill:"#FFD97A",
strokeWidth:0,
shadow:true,
shadowOffsetX:3,
shadowOffsetY:3,
shadowBlur:8,
shadowColor:"rgba(0,0,0,.9)",
shadowOverlap:false,
noShadowOpts:{strokeStyle:"#999",strokeWidth:2},
});
varhideDelayTimer=null;
varhideDelayTimer2=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);
});
