如何处理HTML表单中的文本？ [英] How to process text from HTML form?

问题描述

这可能是一个基本问题 -


我的网页上有一个表格如下：


< span id =" site_search">

< form name =" frmSearch"方法= QUOT;交"行动= QUOT;"风格= QUOT;保证金：0 0 0

15px">

搜索本网站：

< input type =" text" name =" search_field">< input name =" Go" type =" submit"

value =" Go" style =" font-family：Arial，Helvetica，sans-serif">

< / form>

< / span>< br />


当用户点击Go时，如何从这个表单中获取输入并使用它来填充另一个表单（在同一站点内的另一个页面上）按钮？

此外，如果表格为空，如何取消任何操作？

This may be a basic question -

I have a form on my web page that looks like this:

<span id="site_search">
<form name="frmSearch" method="post" action="" style=" margin: 0 0 0
15px ">
Search This Site:
<input type="text" name="search_field"><input name="Go" type="submit"
value="Go" style="font-family:Arial, Helvetica, sans-serif">
</form>
</span><br/>

How do take the input from this form and use it to populate another form (on
another page within the same site) when the user clicks the Go button?
Also, how do I cancel any action if the form is empty?

Thanks in advance.
