TreeSelect,ztree开发的树形下拉选择框插件,支持ie8+,谷歌,火狐,360等浏览器
现在升级2.0名字由原来的DrawMultipleTree改为TreeSelect.js
api更加丰富。结构更加清晰
- 兼容ie8以及各大主流浏览器
- 低侵入式使用
- 使用简单方便
- 继承了ztree高效渲染
1. 引入jquery,ztree,TreeSelect等js和css文件

4.api列表
获取选中文本get selected text value
1 2 | var obj=$( "#yourContentId" ).treeSelect(options); obj.text(); |
获取选中值
1 2 | var obj=$( "#yourContentId" ).treeSelect(options); obj.val(); |
js给组件赋值
1 2 | var obj=$( "#yourContentId" ).treeSelect(options); obj.val([1,2,3,4,5,6,7]); |
默认选中值
方式1:
通过给dom元素设置属性checks来进行设置,格式为:checks="1,2,3,4,5"
例如:
1 2 | < textarea style = "width: 300px;overflow:hidden;" **checks** ="1,11,2,23" type = "text" readonly> </ textarea > |
方式2:
通过optios配置实现配置项为:checks
例如:
1 | $( "#yourContentId" ).treeSelect({checks:[1,2,3],.....}); |
