在C/S系统中有专门的分隔条控件，很方便实现，但在Asp.net中却没有。本文介绍了一种使用JQuery技术实现分隔条的功能。
Javascript代码如下，将该代码保存成JS文件后在HTML中引用。
jsplit 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" "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></div>"); jQuery(_self).children(".jsplit-c").append("<div unselectable='on' + antiD + ":0px;position:absolute;cursor:e-resize;overflow:hidden;z-index:10000;'><div unselectable='on'></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">test</td> <td 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：
