Question

如何在此HTA表单上执行简单验证以确保输入数据并选择了一个选项？这应该很简单，我不确定我错过了什么。

任何答案或建议都将不胜感激。

感谢。

<html><head><title>Write data to text file</title>

<HTA:APPLICATION 
border="thin" 
borderStyle="normal" 
caption="yes" 
maximizeButton="no" 
minimizeButton="yes" 
showInTaskbar="yes" 
innerBorder="yes"
navigable="yes"
scroll="auto"
scrollFlat="yes" />


<script language="javascript">
window.resizeTo(480,150)


function Writedata()
{
var fso = new ActiveXObject("Scripting.FileSystemObject");


var write_id;
write_id = document.getElementById('write_id').value ;

alert('The data has been written to \n' + write_id);
var s = fso.OpenTextFile(write_id, 8, true);

s.WriteLine(document.getElementById('name_id').value);


s.Close();
}

</script>

我很难过，所以我在vbscript中重写了这个。

我已经包含了一些我所做的工作，以便您了解如何写入文本文件，并使用HTA验证您的表单。

vbscript：

Set wshShell = CreateObject( "WScript.Shell" )
strSender = wshShell.ExpandEnvironmentStrings( "%USERNAME%" ) ' Get the current Username


Dim Checkmark

Sub Validate

If form.Flag.checked = True Then ' Find out if your Checkbox is checked
    Checkmark = "*"
Else
    Checkmark = ""
End IF

If form.field1.value = "" Then                    ' Validate the form
    alert "Please enter an number!", "0", "Title"
ElseIf IsNumeric(form.field1.value) = False Then
    alert "Please enter a valid number!", "0", "Title"
ElseIf form.drop_down1.Value = "" Then
    alert "Please select a save location!", "0", "Title"
ElseIf form.field1.value < 100000 Then
    alert "Please enter a six digit number!", "0", "Title"
ElseIf form.field1.value > 999999 Then
    alert "Please enter a six digit number!", "0", "Title"
Else
    SaveData
End If

End Sub


Sub SaveData                    ' Write data to a text file
Set objFSO = CreateObject("Scripting.FileSystemObject")
If objFSO.FileExists(form.drop_down1.Value) Then
Set objFile = objFSO.OpenTextFile(form.drop_down1.Value, 8)
    strLine = form.field1.value & vbtab & Checkmark & vbtab & strSender  & vbtab & Now ' fields that will be written
    objFile.WriteLine strLine
    MsgBox "The Information was successfully written to the file.", "0", "Title"
    objFile.Close
Else
Set objFile = objFSO.CreateTextFile(form.drop_down1.Value) ' If file does not exist, create file
    strLine = form.field1.value & vbtab & Checkmark & vbtab & strSender  & vbtab & Now
    objFile.WriteLine strLine
    MsgBox "The Information was successfully written to the file.", "0", "Title"
    objFile.Close
End If
End Sub

HTML：

<form name="form">
<h2>Imput</h2>
<tr><td><lable>Data: </lable></td><td><input type="text" name="field1" size="25"></td>    </tr>
<tr><td><lable>Save Location: </lable></td><td><select name="drop_down1">
<option type="text" name="select" value="">Select an option</option>
<option type="text" value="SavePath1...">SavePath1</option>
<option type="text" value="SavePath2...">SavePath2</option>
<option type="text" value="SavePath3...">SavePath3</option>
</select></td><td><input type="checkbox" name="Flag" value="">Flag *</td></tr>
</table>
<input type="button" value="Submit" onClick="Validate">
<input type='reset' id='ResetFields' value='Clear Fields' />
</form>
