DHtmlX中combo的基础使用

DHtmlX中combo的使用

combo:比select高级的下拉框

3步创建简单combo

1.连接样式和脚本

<link rel="STYLESHEET" type="text/css" href="dhtmlxCombo/dhtmlxcombo.css" >
<script type="text/javascript" src="dhtmlxCombo/dhtmlxcombo.js"></script>

把css和js放在dhtmlxCombo文件夹下

(也可以直接连CDN,也就是连接官网上，只需要改 href=”http://cdn.dhtmlx.com/edge/dhtmlx.css”
src=”http://cdn.dhtmlx.com/edge/dhtmlx.js”
)

2.body定义容器(通常用div,select也可以)

<select  id="combo_1" name="combo_1">
    <option value="1">a00</option>
    <option value="2">a01</option>
</select>

或

<div id="combo_1" name="combo_1"></div>

3.根据id创建combo

<script type="text/javascript">
  //当容器为select时
  //var myCombo = dhtmlXComboFromSelect("combo_1","combo_1");
  //当容器为div时
  var myCombo = new dhtmlXCombo("combo_1","combo_1");
</script>

注:一定要在容器加载完后再new combo

Combo构造器

new dhtmlXCombo(parent,name,width,type,index,filter,xml,readonly);

parent HTML元素的id，它将用作用途·父类(或对象本身)
name HTML元素的name
width combo的宽度,像素(px)为单位(String)
type combo选项使用的类型(可选)
index
filter
xml
readonly

加载数据

用combo.addOption(value,label,css,img_src);

value (String) 选项的id
label (String)选项的值
css (String)附加的样式(可选)
img_src (String)选项图标图像的路径
