我有一个用户列表,每个用户都有一个角色。
被选为“Líder”的用户不能有多个角色,只能“Líder”。
如果用户选择其他选项(女儿),则应禁用“Líder”选项。不是“Líder”的用户可以有多个角色。
以下是问题的模拟:jsfiddle
HTML:
<select class="selectpicker" id="funcao" multiple data-max-options="1">
<option value="lider">Líder</option>
<option value="conhecimento">Para Conhecimentor</option>
<option value="participante">Participante</option>
</select>
<br><br>
<select class="selectpicker" id="funcao" multiple data-max-options="1">
<option value="lider">Líder</option>
<option value="conhecimento">Para Conhecimentor</option>
<option value="participante">Participante</option>
</select>
<br><br>
<select class="selectpicker" id="funcao" multiple data-max-options="1">
<option value="lider">Líder</option>
<option value="conhecimento">Para Conhecimentor</option>
<option value="participante">Participante</option>
</select>
<br><br>
<select class="selectpicker" id="funcao" multiple data-max-options="1">
<option value="lider">Líder</option>
<option value="conhecimento">Para Conhecimentor</option>
<option value="participante">Participante</option>
</select>
JS:
$('select').change(function(){
var sel = $(this);
var data = sel.data('prev');
var val = sel.val();
var prev;
if(data){ prev = data.val; }
sel.data('prev', {val: val});
sel.nextAll().each(function(){
if(prev){
$(this).find("[value='" + prev+ "']").prop("disabled",false);
$('.selectpicker').selectpicker('refresh');
}
$(this).find("[value='" + val + "']").prop("disabled",true);
$('.selectpicker').selectpicker('refresh');
});
$('.selectpicker').selectpicker('refresh');
});

您可以使用以下代码检查效果 - jsfiddle
$('select').change(function() {
var sel = $(this);
disableThis(sel);
$('.selectpicker').selectpicker('refresh');
});
function disableThis(sel) {
var temSelecionado = false;
$("option[value='1']").each(function() {
if (this.selected) {
temSelecionado = true;
$(this).parent().each(function() {
$(this.options).each(function() {
if ($(this).val() != "1") {
$(this).prop("disabled", true);
}
})
});
}
else {
$(this).parent().each(function() {
$(this.options).each(function() {
if ($(this).val() != "1") {
$(this).prop("disabled", false);
}
})
});
}
});
}
