问题描述
大家好，
我有一个javascript程序，用于删除文件，如下所示，
hi all,
I have a javascript program to delete a file as follows,
var fileSystem = new ActiveXObject("Scripting.FileSystemObject");
var fileName = fileSystem.GetFile("D:/hi.xml");
fileName.Delete();
如果在指定的位置不存在"hi.xml"，那么脚本将给出错误消息找不到文件"，并且该脚本将停止执行.但是在这里，我想继续执行.是否有任何方法可以检查加载是否成功?
我该如何移动?
请帮助我
if "hi.xml" is not there in that specified location, then the script is giving an error message as "file not found", and it stops the execution.but here i want to continue the execution.is there any method to check whether the loading is success ot not?
how can i move with this?
please help me
推荐答案
使用try catch
Use try catch
try
{
//Run some code here
}
catch(err)
{
//Handle errors here
}

尝试一下
Try this
<html>
<body>
<script language="JScript">
<!--
function remove()
{
var myObject;
myObject = new ActiveXObject("Scripting.FileSystemObject");
var f = myObject.GetFile("c:\\test.txt");
f.Delete();
}
//-->
</script>
Delete file "mytest.txt".
<form name="myForm">
<input type="Button" vvalue="Delete File" onClick='remove()'>
</form>
</body>
</html>
谢谢
