jQuery UI Autocomplete控件下拉列表固定高度

2017-04-11 15:13 501 查看

jQuery ui Autocomplete控件下拉列表高度默认是自适应的，有多少数据就会加载出来多少行。以下是给下拉列表设置一个默认高度并添加滚动条的解决办法。

在样式里添加以下代码

.ui-autocomplete {
max-height: 150px; //默认最大高度150像素
overflow-y: auto; //添加滚动条
/* 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; //解决IE6下不识别max-height
}
