我一直在使用这个自定义 Bootstrap 选择插件 BSMultiselect 。我需要在页面加载后使用 jQuery/Javascript 选择一些选项。
API 文档不太清楚如何执行此操作。我尝试过的是:
var bsMultiSelect = $('#facilityFilter').BsMultiSelect();
bsMultiSelect.updateOptionSelected(0);
这实际上没有任何作用。
最佳答案
为了选择一个选项，您需要首先设置 selected更新 bsMultiSelect 之前的属性。
代码片段:
$(function () {
var $multiSelects = $("select[multiple='multiple']");
$multiSelects.bsMultiSelect();
// set the selected attribute...
$multiSelects.find('option').eq(0).prop('selected', 'selected');
// ....so, update the bsMultiSelect
$multiSelects.data('DashboardCode.BsMultiSelect').updateOptionSelected(0);
});.row {
background: #f8f9fa;
margin-top: 20px;
}
.col {
border: solid 1px #6c757d;
padding: 10px;
