form action参数传递的几种方式

<!--
个人认为form的default method 是 ”post“，action后的#/？相同的效果，“.”代表current folder。
<form action="#"<?php if (isset($_GET['sample'])) echo "&"; ?>&this.data_format.value name=format_form>
<?php
if (isset($_GET['sample']))
echo "<input type=hidden   name='sample' value=" . $_GET['sample'] .">";
// note the space before "/>"
?>
-->
<form action="#" method=get name=format_form>
   <?php
if (isset($_GET['sample']))
echo "<input type=hidden   name='sample' value=" . $_GET['sample'] .">";
   ?>

显示格式选择

<SELECT size=1 name="data_format" οnchange="submit()">

<OPTION value="0" <?php if ($format==0) echo "selected"; ?> >简略</OPTION>

<OPTION value="1" <?php if ($format==1) echo "selected"; ?> >详细</OPTION>

</select>

-----------------------------------------如何用js改变form的action属性值-------------------------

只要将form设定一个id如id=“form1”，然后在submit的时候调用js函数，在函数中引用=

"?margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px; color:rgb(69,69,69); font-family:'Microsoft Yahei',微软雅黑,Tahoma,Arial,Helvetica,STHeiti; font-size:14px; line-height:25px"> Eg:

<script lang="javascript">

function go()

{

var value=("T1").value;

="?cx="+value;

}

</script>

引用该函数的form：

<form method=post οnsubmit="go();">

我的方法：

if (document.form1.search_option1.value=="data" )

 {

document. = ""; //js control the form by id,not name

document.form1.search_option2. = 1;

document.form1.search_option2.options[0] = new Option("Dataset");

document.form1.search_option2.options[0].value = "Dataset_ID"; // 文本型value 必须用""

document.form1.search_option2.options[1] = new Option("位址");

document.form1.search_option2.options[1].value = "site";

document.form1.search_option2.selectedIndex = 0;

}

引用的form

<form action="b1_customer.php" method=post name="from1" >

        <SELECT onChange=checkSearch() size=1 name="search_option1" >xxxx</select>

<SELECT size=1 name="search_option2" >xxx</select>
