//=========== html 下拉栏类

//根据一个数组生成一个下拉框

//功能:可以初始化为选中其中的一项,默认为第一项

下拉框: select

选项: option

选中的: selected

名字: name

ID: id

css 样式: class

项目标签:

标签值:

//----------------------------------------------------------------------------------------

$dbc=mysql_connect();

mysql_select_db("felonious",$dbc);//连接数据库

$q=mysql_query("select * from felonious",$dbc);//进行数据库操作

while($row=mysql_fetch_array($q))

{

$rows[]=$row;

}

$Item=array("NULL"=>"没有可选项","1"=>"ffff","2"=>"aaaaaaa");

$selected=array("10","15","20"); //单选时,第一个元素有效

$ds = new CxSelectDown();

$ds->dbitem=true;

$ds->itemvalue="auto_id"; //项的值,数据表里的字段名

$ds->itemlable="felonious";//项的标签,数据表里的字段名

$ds->multiple=false;

$ds->SetName("Test");

$ds->SetStyle("ClassName");

$ds->SetID("test");

$ds->SetDir("right");

$ds->SetAccKey("b");

$ds->SetDisabled(false);

$ds->SetSize(0);

$ds->SetItem($rows,$selected);

echo $ds->show();

//---------------------------------------------------------------------------------------

最简单用法

$ds = new CxSelectDown();

$ds->SetItem($Item);

echo $ds->show();

//----------------------------------------------------------------------------------------

根据从数据库取得的 row 生成一个下拉框

方法:

Setitem 设置项目数据参数 $rows 项目数组,$selected 当前选中的项目该值为项目的 value 或数组(在multiple时)

属性:

dbitem [true/false] default false

itemvalue 项目的值,只有 dbitem 是 true 时有效

itemlable 项目的标签,只有 dbitem 是 true 时有效

如果 dbitem 为 true 时方法 Setitem 的数据必须为用 mysql_fetch_array 取的数据

否则数组结构为 $Item=array("NULL"=>"没有可选项","1"=>"ffff","2"=>"aaaaaaa","value"=>"lable");

class CxSelectDown

{

//=========================

// 值标签

var $_NullItem=array("NULL"=>"没有可选项");

//=========================

var $dbitem=false; //如果是从数据库取得的数组还要设置下面几个参数

var $itemvalue; //项的值

var $itemlable;//项的标签

var $multiple=false; //多选,列表框
