本文向大家介绍jQuery bt气泡实现悬停显示及移开隐藏功能的方法,包括了jQuery bt气泡实现悬停显示及移开隐藏功能的方法的使用技巧和注意事项,需要的朋友参考一下

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:

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},
});
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);
});

附:jQuery.bt.min.js插件完整代码如下:
