我的任务
分享请问newWindow.document.execCommand('saveas',....)如何限制弹出的对话框只能是htm格式，不能选择txt格式？
类似csdn保存文章，由于保存为txt有问题，所以只想保存为htm，能否限制保存的文件类型啊？
...全文
请发表友善的回复…

将上面的 cDialog.Filter改为你自己需要的 cDialog.Filter="HTM Files (*.htm,*.html)|*.htm,*.html"

1.使用CommandDialog作为选择对话框
2.使用FSO对象来写文件
<OBJECT id=cDialog codeBase=http://activex.microsoft.com/controls/vb5/comdlg32.cab
height=0px width=0px classid=CLSID:F9043C85-F6F2-101A-A3C9-08002B2F49FB></OBJECT>
<SCRIPT language=javascript>
function SaveDocument(){
cDialog.CancelError=true;
try{
cDialog.Filter="HTM Files (*.htm)|*.htm|Text Files (*.txt)|*.txt"
cDialog.ShowSave();
var fso = new ActiveXObject("Scripting.FileSystemObject");
var f = fso.CreateTextFile(cDialog.filename, true);
f.write(document.body.innerHTML);
f.Close();
sPersistValue=document.body.innerHTML;}
catch(e){
var sCancel="true";
return sCancel;}
}
</SCRIPT>
<BUTTON onclick=SaveDocument();>保存</BUTTON>
2.使用FSO对象来写文件
<OBJECT id=cDialog codeBase=http://activex.microsoft.com/controls/vb5/comdlg32.cab
height=0px width=0px classid=CLSID:F9043C85-F6F2-101A-A3C9-08002B2F49FB></OBJECT>

catch(e){

return sCancel;}

没反应？不会吧
cDialog.Filter="HTM Files (*.htm,*.html)|*.htm,*.html"
改正一下 ，改为cDialog.Filter="HTM Files (*.htm,*.html)|*.htm;*.html"
cDialog.Filter="HTM Files (*.htm,*.html)|*.htm,*.html"
改正一下 ，改为cDialog.Filter="HTM Files (*.htm,*.html)|*.htm;*.html"
