使用鼠标选择单个元素或一组元素。
如需了解更多有关 selectable 交互的细节,请查看 API 文档 可选择小部件(Selectable Widget)。
在某个 DOM 元素上或者一组元素上启用 selectable 功能。通过鼠标拖拽选择条目。按住 Ctrl 键,选择多个不相邻的条目。
<!doctype html> < html lang = "en" > < head > < meta charset = "utf-8" > < title >jQuery UI 选择(Selectable) - 默认功能</ title > < link rel = "stylesheet" href = "//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css" > < script src = "//code.jquery.com/jquery-1.9.1.js" ></ script > < script src = "//code.jquery.com/ui/1.10.4/jquery-ui.js" ></ script > < style > #feedback { font-size: 1.4em; } #selectable .ui-selecting { background: #FECA40; } #selectable .ui-selected { background: #F39814; color: white; } #selectable { list-style-type: none; margin: 0; padding: 0; width: 60%; } #selectable li { margin: 3px; padding: 0.4em; font-size: 1.4em; height: 18px; } </ style > < script > $(function() { $( "#selectable" ).selectable(); }); </ script > </ head > < body > < ol id = "selectable" > < li class = "ui-widget-content" >Item 1</ li > < li class = "ui-widget-content" >Item 2</ li > < li class = "ui-widget-content" >Item 3</ li > < li class = "ui-widget-content" >Item 4</ li > < li class = "ui-widget-content" >Item 5</ li > < li class = "ui-widget-content" >Item 6</ li > < li class = "ui-widget-content" >Item 7</ li > </ ol > </ body > </ html > |
让 selectable 条目显示为网格,使用 CSS 使得它们带有相同的尺寸且浮动显示。

写一个函数,在 stop
事件发生时触发,来收集被选中条目的索引值。呈现这些值作为反馈,或者以数据字符串形式进行传递。
