我用分层次电路图仿了一个振荡器,现在想把它封装起来,以后可以直接用“place part”的方法调用它,500) {this.resized=true; this.width=500; this.alt='这是一张缩略图,点击可放大。\n按住CTRL,滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/68/1986281220153332.gif');}" onmousewheel="return imgzoom(this);">但发现提示错误,
ERROR -- Less than 2 connections at node N02143
ERROR -- Node N02143 is floating
应该怎样封装才好呢,请高人指点~~~~~~~
