表单元素的写法及与后台php的交互

1、
<select class="textEnaSty" name="Port" size="1" onchange="ObtainIPAddr_Enable(this.value)">
<option value="120">Hello</option>
<option value="240">World</option>
</select>

2、页面上不显示，会将内容提交到后台
<input name="Port" type="hidden" value="hello">

3、radio 选项互斥
<input class="textEnaSty" name="FaultResume" type="radio" value="0" checked>

4、php 使能checked的用法
<?php
$Checked="checked"; //勾选上
$Checked=""; // 未勾选
?>

<input name="Port" type="checkbox" value="1" checked>Hello

5、php 使能的 disabled的用法
<?php

$Enable = "disabled";  //disabled = 0 不给用户输入
$Enable = "enabled"; //enabled = 1 给用户输入
?>

<input name="Port" type="text" onChange=GetPmCenterEnable() <?=$Enable; ?> value="1">Hello

6、表单以数组方式提交

   

<style type="text/css" media="screen">
    .tableStyle1{
          /*背景 红色*/
          background-color:#F00C99;
           /*文本*/
           text-align:justify;
          /*字体*/
           font-family:Georgia,serif;
           font-style:normal;
           font-size:10px;
           font-weight:bolder;
           /*黑色*/
           color:#000F0B; 
          /*定位*/
           margin:auto;
           border-width:50px; 
           border-style:solid;
           /*粉红 如果不设则为灰色*/
           border-color:#CE1AD4;
           border-color:transparent;
           padding:50px;

    }
    .tdStyle1{
        /*背景 浅绿*/
        background-color:#09D6F8;
        /*文本*/
        text-align:center; 
        /*字体*/
        font-family: Times,Sans-serif,Fantasy;
        font-style:normal;

        /*字体浅灰*/
        color:#40308A;
        font-size:20px;
        /*定位*/
        margin:auto;
        border-style:none;
        border-width:5px;
        /*粉红*/
        border-color:#DE2AD3;

        /*border:1px solid #FFFFFF;*/
     /*   border-1px;
        border-style:solid;
        border-color:#FFFFFF;*/
      /*  padding:0px;*/

    }
   .inputStyle{
        font-size:15px;
        color:#F51515;
        padding:0px;
   }
