在C/S系統(tǒng)中有專門的分隔條控件，很方便實(shí)現(xiàn)，但在Asp.net中卻沒(méi)有。本文介紹了一種使用JQuery技術(shù)實(shí)現(xiàn)分隔條的功能。
Javascript代碼如下，將該代碼保存成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" ? "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;
      }


    });
  }
});

按以下步驟修改HTML文件：
1. 增加對(duì)JQuery和剛剛生成的jsplit.js文件的引用。

 <script language='javascript' src='http://www.gimoo.net/t/1902/jquery-1.4.4.min.js'></script>
<script language='javascript' src='http://www.gimoo.net/t/1902/jsplit.js'></script> 

2. 為要被拖動(dòng)大小的DIV或TD定義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調(diào)用Split。

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

這樣就實(shí)現(xiàn)了客戶端的分隔條的功能，如下圖所示：

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持綠夏網(wǎng)。
