用JQuery在网页中实现分隔条功能的代码

Javascript代码如下，将该代码保存成JS文件后在HTML中引用。

jQuery.noConflict(); 
jQuery.fn.extend({ 
jsplit: function (j) { 
return this.each(function () { 
j = j || {}; 
j.Btn = j.Btn || {}; 
j.Btn.oBg = j.Btn.oBg || {}; 
j.Btn.cBg = j.Btn.cBg || {}; 
var jun = { MaxW: "600px" 
, MinW: "260px" 
, FloatD: "left" 
, IsClose: false 
, BgUrl: "" 
, Bg: "#fff" 
, Btn: { btn: true 
, oBg: { Out: "#333", Hover: "orange" } 
, cBg: { Out: "#333", Hover: "orange"} 
} 
, Fn: function () { } 
} 
j.MaxW = parseInt(j.MaxW) || parseInt(jun.MaxW); 
j.MinW = parseInt(j.MinW) || parseInt(jun.MinW); 
j.FloatD = j.FloatD || jun.FloatD; 
j.IsClose = j.IsClose != undefined ? j.IsClose : jun.IsClose; 
j.BgUrl = j.BgUrl || jun.BgUrl; 
j.Bg = j.Bg || jun.Bg; 
j.Btn.btn = j.Btn.btn != undefined ? j.Btn.btn : jun.Btn.btn; 
j.Btn.oBg.Out = j.Btn.oBg.Out || jun.Btn.oBg.Out; 
j.Btn.oBg.Hover = j.Btn.oBg.Hover || jun.Btn.oBg.Hover; 
j.Btn.cBg.Out = j.Btn.cBg.Out || jun.Btn.cBg.Out; 
j.Btn.cBg.Hover = j.Btn.cBg.Hover || jun.Btn.cBg.Hover; 
j.Fn = j.Fn || jun.Fn; 
var antiD = j.FloatD == "left" ? "right" : "left"; 
if (j.MinW > j.MaxW) { 
var amax = j.MaxW; 
j.MaxW = j.MinW; 
j.MinW = amax; 
}; 
var _self = this; 
var Close = false; 
jQuery(_self).css({ position: "relative", float: j.FloatD, overflow: "hidden", padding: "0px" }); 
jQuery(_self).wrapInner("<div class='jsplit-c' style='top:0px;z-index:9999;zoom:1;width:100%;overflow:hidden;position:relative;height:100%'></div>"); 
jQuery(_self).children(".jsplit-c").append("<div class='jsplit-e' unselectable='on' style='background:#fff;height:100%;width:6px;top:0px;-moz-user-select:none;" + antiD + ":0px;position:absolute;cursor:e-resize;overflow:hidden;z-index:10000;'><div class='jsplit-e-handle' unselectable='on' style='height:40px;width:100%;top:50%;margin-top:-20px;left:0;position:absolute;cursor:pointer;-moz-user-select:none;'></div></div>"); 
var dw = jQuery(_self).width(); 
var jsplitc = jQuery(_self).children(".jsplit-c"); 
var jsplite = jsplitc.children(".jsplit-e"); 
var jsplith = jsplite.children(".jsplit-e-handle"); 
if (j.Btn.btn == false) { jsplith.css({ display: "none" }) }; 
if (jQuery.browser.msie) { document.execCommand("BackgroundImageCache", false, true); } 
if (dw > j.MaxW) { jQuery(_self).css({ width: j.MaxW }); } 
if (dw < j.MinW) { jQuery(_self).css({ width: j.MinW }); } 
jsplite.css({ background: j.Bg, "background-image": j.BgUrl, opacity: 0 }) 
if (j.IsClose != false) { 
jsplith.css({ background: j.Btn.cBg.Out, "background-image": j.BgUrl }) 
_selfclose(); 
} else { 
jsplith.css({ background: j.Btn.oBg.Out, "background-image": j.BgUrl }) 
} 
jsplith.hover(function () { 
if (Close == false) { 
jQuery(this).css({ background: j.Btn.oBg.Hover, "background-image": j.BgUrl }) 
} else { jQuery(this).css({ background: j.Btn.cBg.Hover, "background-image": j.BgUrl }) } 
}, function () { 
if (Close == false) { 
jQuery(this).css({ background: j.Btn.oBg.Out, "background-image": j.BgUrl }) 
} else { jQuery(this).css({ background: j.Btn.cBg.Out, "background-image": j.BgUrl }) } 
}) 
jQuery(_self).hover(function () { if (Close == false) jsplite.stop().animate({ opacity: 0.85 }, 200) }, function () { if (Close == false) jsplite.stop().animate({ opacity: 0 }, 2000) }) 
jsplite.mousedown(function (e) { 
j['Fn'] && j['Fn'].call(_self); 
var screenX = e.screenX, w = jQuery(_self).width(); 
jQuery(document).mousemove(function (e2) { 
curW = j.FloatD == "left" ? w + (e2.screenX - screenX) : w - (e2.screenX - screenX); 
if (curW >= j.MaxW) { curW = j.MaxW; }; 
if (curW <= j.MinW) { curW = j.MinW; }; 
jQuery(_self).css({ width: curW }); 
dw = curW; 
}); 
jQuery(document).mouseup(function () { 
jQuery(document).unbind(); 
}); 
if (Close == true) { 
jQuery(this).css({ cursor: "e-resize", opacity: 0.8 }); 
jQuery(_self).animate({ width: dw }, 200); 
Close = false; 
}; 
return false; 
}); 
jsplite.dblclick(function () { 
if (Close == false) { 
_selfclose(); 
}; 
return false; 
}); 
jsplith.click(function () { 
if (Close == false) { 
_selfclose(); 
}; 
return false; 
}); 
function _selfclose() { 
jsplite.css({ cursor: "pointer", opacity: 1 }); 
jsplith.css({ background: j.Btn.cBg.Out, "background-image": j.BgUrl }); 
jQuery(_self).animate({ width: "6px" }, 400); 
Close = true; 
} 
}); 
} 
});

按以下步骤修改HTML文件：
1. 增加对JQuery和刚刚生成的jsplit.js文件的引用。

<script language='javascript' src='jquery-1.4.4.min.js'></script> 
<script language='javascript' src='jsplit.js'></script>

2. 为要被拖动大小的DIV或TD定义ID。

<table> 
<tr> 
<td id="tt" style="background:#999999">test</td> 
<td style="background:#009999" width="400">test Table</td> 
</tr> 
</table>

3. 增加Javascript调用Split。

<script type="text/javascript"> 
$(document).ready(function(){ 
jQuery('#tt').jsplit(); 
}); 
</script>

这样就实现了客户端的分隔条的功能，如下图所示：
