Han*_*nth 3 vbscript batch-file hta
如何将退出状态从HTA(vbscript)返回到调用批处理文件？
我的批处理文件代码
@echo OFF
echo Configuring Test...
call AppConfigurationEditor.hta
call TestConfigurationEditor.hta
1.如果用户点击第一个HTA上的CANCEL按钮,我不想运行第二个HTA.
2.Batch脚本调用/立即显示第二个HTA,而不是等到第一个HTA关闭.
HTA没有实现将错误级别返回给调用者进程的方法.
WScript.Quit不能使用.lenguage引擎vbscript/javascript/...是相同的,但是实例化引擎的主机对象不是习惯性的Windows脚本主机,它是一个浏览器对象,所以WScript对象不存在.
window.close方法不能使用.它可以关闭hta,但不会给出返回值.
使用hta将值返回给调用进程的常用方法是将此值保存在文件或注册表中.然后调用进程可以检索所需的值.
如果需要errorlevel,则没有直接的方法.但是可以实施间接方法.只需使用WMI检索正在运行的进程列表,找到当前的hta,并为此进程调用Terminate方法,该方法允许设置退出值.

</STYLE>
<SCRIPT language="Javascript">
function closeWithErrorlevel(errorlevel){
var colProcesses = GetObject('winmgmts:{impersonationLevel=impersonate}!\\\\.\\root\\cimv2').ExecQuery('Select * from Win32_Process Where Name = \'mshta.exe\'');
var myPath = (''+location.pathname).toLowerCase();
var enumProcesses = new Enumerator(colProcesses);
for ( var process = null ; !enumProcesses.atEnd() ; enumProcesses.moveNext() ) {
process = enumProcesses.item();
if ( (''+process.CommandLine).toLowerCase().indexOf(myPath) > 0 ){
process.Terminate(errorlevel);
}
}
}
function closeHTA(value){
// test close of window. Use default value
if (typeof value === 'undefined') value = 0;
try { closeWithErrorlevel(value) } catch (e) {};
}
</SCRIPT>
</HEAD>
<BODY>
<button onclick="closeHTA(0);">close application 0</button>
<button onclick="closeHTA(1);">close application 1</button>
<button onclick="closeHTA(2);">close application 2</button>
</BODY>
<script language="Javascript">
window.attachEvent('onbeforeunload',closeHTA);
</script>
</HTML>
然后你可以从批处理文件中调用它
start "" /wait testCloseHTA.hta
if errorlevel 2 (
echo option 2 has been selected
) else if errorlevel 1 (
echo option 1 has been selected
) else (
echo option 0 has been selected
)
