js代码实现如下：

function DrawPolyline()

var mxOcx = document.all.item("MxDrawXCtrl");

mxOcx.focus();

var point1 = mxOcx.GetPoint(false,0,0,"\n 点取开始点:");

if(point1 == null)

return;

//mxOcx.PathMoveToEx(point1.x,point1.y,10,10,0.0);

mxOcx.PathMoveTo(point1.x,point1.y);

var point2 = mxOcx.GetPoint(true,point1.x,point1.y,"\n 点取下一个:");

if(point2 == null)

return;

var tmpobj = new Array();

//mxOcx.PathLineToEx(point2.x,point2.y,10,10,0.0);

mxOcx.PathLineTo(point2.x,point2.y);

var iCount = 0;

var id = mxOcx.DrawLine(point1.x,point1.y,point2.x,point2.y);

tmpobj[iCount] = id;

iCount = iCount + 1;

point1 = point2;

while(true)

var point2 = mxOcx.GetPoint(true,point1.x,point1.y,"\n 点取下一个:");

if(point2 == null)

break;

mxOcx.PathLineTo(point2.x,point2.y);

var id = mxOcx.DrawLine(point1.x,point1.y,point2.x,point2.y);

tmpobj[iCount] = id;

iCount = iCount + 1;

point1 = point2;

var i = 0;

for(;i < iCount;i++)

mxOcx.Erase(tmpobj[i] );

var lId = mxOcx.DrawPathToPolyline();

// 把新绘的pl线变成双线。

var param = mxOcx.Call("Mx_NewResbuf","");

param.AddLong(lId);

// 双线的宽度。

var lineWidth = 2;

param.AddDouble(lineWidth);

// 调用变双线函数。

var ret = mxOcx.CallEx("ExApp_MakeDoubleLine",param);

if(ret.AtString(0) == "Ok")

// 返回的绘制的双线对象id.

alert(ret.AtLong(1));

// 删除旧的pl线。

mxOcx.Erase(lId);
