jQuery UI Autocomplete控制元件下拉列表固定高度
阿新 • • 發佈:2019-01-08
jQuery ui Autocomplete控制元件下拉列表高度預設是自適應的,有多少資料就會加載出來多少行。以下是給下拉列表設定一個預設高度並新增滾動條的解決辦法。
- 在樣式裡新增以下程式碼
.ui-autocomplete {
max-height: 150px; //預設最大高度150畫素
overflow-y: auto; //新增滾動條
/* prevent horizontal scrollbar */
overflow-x: hidden;
}
/* IE 6 doesn't support max-height
* we use height instead, but this forces the menu to always be this tall
*/
* html .ui-autocomplete {
height: 150px; //解決IE6下不識別max-height
}
