要在单击 Enter 键时调用 VBScript 函数?

问题描述

我创建了一个 VBScript 函数 OnRefreshList()，单击刷新列表"按钮即可调用该函数.

I have created a VBScript function OnRefreshList() which is called on the click of a button "Refresh List".

Sub OnRefreshList ()

Initdatatable(false)

if ReadFilters() = false then
    msgbox "It is not possible to refresh the whole orders list. Please enter more filters"
    exit sub
end if

End Sub

刷新列表"按钮定义为

 <td class="button cmd" valign="center" nowrap id="cmdRefresh" onclick="OnRefreshList()" title="Refresh the order list">Refresh List</td>

当我点击按钮时，这个功能工作正常.

This function is working fine when I am clicking on the button.

现在我想在按下键盘上的 Enter 键时调用这个函数.

Now I want to call this function when I press the Enter key from the key board.

为此，我尝试更改以下代码段，但对我不起作用.

For this I tried to change the following piece of code but it didnt worked for me.

<td class="button cmd" valign="center" nowrap id="cmdRefresh" onKeydown="vbscript: if (event.keyCode==13) then OnRefreshList()" onclick="OnRefreshList()" title="Refresh the order list">Refresh List</td>

如果有人有答案，请帮助我.

Please help me if anyone has an answer to it.

推荐答案

您的 onKeydown 事件中没有正确的 VBScript 语句.应该是:

Your onKeydown event does not have a correct VBScript statement in it. It should be:

onKeydown="vbscript: if event.keyCode=13 then OnRefreshList()"

注意单个 = 符号和缺少括号(它们不是强制性的).如果您更熟悉 javascript:您可以混合使用 VBScript 和 Javascript:

Notice the single = sign and the lack of parenthesis (they are not mandatory). If you are more comfortable with javascript: You can mix VBScript and Javascript:

onKeydown="javascript: if (event.keyCode==13) OnRefreshList(); //this will work too!"
