推荐答案

JAJANCHERIAN，

我认为无需获取文本框ID.您可以将文本框对象直接发送到您的函数.
例如:

Hi SHAJANCHERIAN,

I think no need to get Textbox id. you can sent the text box object directly to your function.
for example:

<script type="text/javascript">
function gettextboxobject()
{

}
</script>

<input type="text" id="textbox1" onblur="gettextboxobject(this)"  önfocus="gettextboxobject(this)" />

您可以直接获取文本框对象.

you can get the textbox object directly.

please reply if you want more.

您可以尝试查看DOM元素document.activeElement.据我所知，它不能在所有浏览器中一致地工作，但是它应该可以帮助您入门.

从这里开始，

You can try taking a look at DOM Element document.activeElement. As far as I remember, it doesn''t work consistently across browsers, but it should get you started.

From here on, Google[^] is your friend. I''m sure you''ll find something to help you
