CAD关于标注样式删除标注样式（com接口网页版）

在删除标注样式前，最好判断图上有没有标注对象正在使用该样式，如果有的话就不要删除文字样式

js代码如下：

function DelDim() {var winWidth = 440;var winHeight = 140;var winLeft = (screen.width - winWidth) / 2;var winTop = (screen.height - winHeight) / 2 - 20;var str = 'dialogHeight:' + winHeight + 'px;dialogWidth:' + winWidth + 'px;dialogTop:' + winTop + 'px;dialogLeft:' + winLeft + 'px;resizable:yes;center:yes;status:no;'var rt = window.showModalDialog("Gettext.htm?tmp=" + Math.random(), "输入图层名", str);var txt;if (typeof (rt) == "undefined") {return;} else {var arr = rt.split(",");txt = arr[0];}var database =mxOcx.GetDatabase();database.CurrentlyDimstyleName = "Standard";//返回数据库中的样式表对象var DimStyleTable = database.GetDimStyleTable();//得到样式表表中的样式对象var DimStyleRec = DimStyleTable.GetAt(txt, false);if (DimStyleRec == null)return;//删除对象DimStyleRec.Erase();alert("成功删除标注样式");}
