javascript 实现的文件拷贝
刚学习js，做了个文件拷贝练习，只在IE下实现了，火狐不好用，有待改进........
代码如下，仅供参考.
FileCopy.html
<html><head><title>FileCopy LX</title><script type="text/javascript" src="FileCopy.js"></script></head><body><div align="center"><h1><font color="#00eeff">File Copy</font> </h1><hr color="#0099ff"/></div><br/><div><table align="left"><tr><td><font size="5">Choose Folder CopyFrom: </font></td><td><input type="text" name="pathFrom" id="pathFrom" value ="" size="100" /><input type="button" name="btnSelectPath" id="btnSelectPath" value ="Chose Folder" /> <hr color="#A4D3EE"/></td></tr></table></div><br/><br/><br/><br/><div><table align="left"><tr><td><font size="5">Choose Folder CopyTo:&nbsp;&nbsp;&nbsp; </font></td><td><input type="text" name="pathTo" id="pathTo" value ="" size="100" /><input type="button" name="btnSelectPath" id="btnSelectPath" value ="Chose Folder" /> <hr color="#A4D3EE"/></td></tr></table></div><br/><br/><br/><hr color="RGB(250,120,120)"/><div ><div ><font color="#436EEE"><b>Please write the name of files you wanted to copy to the table</b></font></div><input type="button" name="clearTable" id ="clearTable" value="clear talbe" /><table id = "myTable" border="1" width="40%" bordercolor="#BCD2EE" cellpadding="0" cellSpacing="0" align="center"><tr ><td align="center">the name of the files must be contains the Extension </td></tr><tr><td><input type="text" name="file" id="file0" value="" size="100"/></td></tr><tr><td><div align="right" ><input type="button" name="addRow" id="addRow" value="addRow" /></div></td></tr></table></div><hr color="RGB(250,120,120)"/><div align="right" ><input type="button" name="btnRun" id="btnRun" value="Run" /></div></body></html>

FileCopy.js
