//树图拉伸

   jQuery(function ($){

                 var doc = $(document), dl = $(".side-tree"), dc = $(".tree-content");

                 var sum = dl.css("left") + dc.width() +

                    $(".tree-handler").mousedown (function (e) {

                       var tree = $(this);

                       var deltaX = e.clientX-(parseFloat(tree.css("left")) || parseFloat(tree.prop("clientLeft")));

                       doc.mousemove(function (e){

                          var lt = e.clientX - deltaX;

                          lt = lt < 188 ? 188 : lt;

                          dl.width(lt-86)//目录树宽

                          $(".tree-handler").css("left",dl.width()+42);//拖动把手位置

                          var treeConLeft = $(".tree-handler").css("left");//右侧内容区位置

                          var reg = new RegExp("px","g");

                          treeConLeft = treeConLeft.replace(reg, "");

                          treeConLeft = treeConLeft-26 +"px";

                          $(".tree-content").css("margin-left",treeConLeft)

                       });

                    })

                 doc.mouseup (function(){

                    doc.unbind("mousemove");

                 });

                 doc[0].ondragstart = doc[0].onselectstart = function (){

                    return false;

                 };

              });

});
