我正在使用Bootstrap-Multiselect功能；我想在单击“x”时取消选择一个选项。 这是我正在寻找的一个简单示例。
$(document).on("click", '#remove', function(a) {
var tag = this.getAttribute("value");
$('#tags').find('[value=' + tag + ']').prop('selected', false);
});<html>

<div value='Php' id='remove'>x</div>

这可以通过取消选择所有然后获取所选值并从中删除目标标记并重新选择其余部分然后最后刷新选择来实现:
$(document).on("click", '#remove', function(a) {
var tag = this.getAttribute("value");
var values = $('#tags').val();
if(values){
$('#tags').selectpicker('deselectAll');
$('#tags').selectpicker('val', values.filter(function(e) {return e !== tag }));
$('#tags').selectpicker('refresh');
}
