我想根据数组值创建一个动态 select2 下拉列表并禁用下拉列表中的选项。当我在当前选择框中选择该选项时，该选项将在其他选择框下拉列表中被禁用。 这是我的代码
var selectArray = [{id: 0, value: 'test'}, {id: 1, value: 'test1'},{id: 2, value: 'test2'}, {id: 3, value: 'test3'},{id: 4, value: 'test4'}, {id: 5, value: 'test5'}];
var data = [{id:1, text: 'value1'},{id:2, text: 'value2'},{id:3, text: 'value3'},{id:4, text: 'value4'},{id:5, text: 'value5'}];
$.each(selectArray, function( index, value ) {
var html = '<li class="m-b-20"><select id="select_id_'+ value.id +'" class="select2-option"></select></li>';
$('#selectbox').append(html);
});
$(".select2-option").select2({
minimumResultsForSearch: -1,
data: data
});ul li {
list-style: none;
}
select {
width: 200px;
}
.m-b-20 {
margin-bottom: 20px;
}<html>

我找到了用于显示的解决方案，并在下拉列表中隐藏了选项。
var selectArray = [ {id: 1, value: 'test1'},{id: 2, value: 'test2'}, {id: 3, value: 'test3'},{id: 4, value: 'test4'}, {id: 5, value: 'test5'}];
var data = [{id: '', text: '--none--'}, {id:'1', text: 'value1'},{id:'2', text: 'value2'},{id:'3', text: 'value3'},{id:'4', text: 'value4'},{id:'5', text: 'value5'}];
$.each(selectArray, function( index, value ) {
var html = '<li class="m-b-20"><select id="select_id_'+ value.id +'" class="select2-option"></select></li>';
$('#selectbox').append(html);
});
$.fn.select2.amd.define('select2/data/customAdapter', ['select2/data/array', 'select2/utils'],
function (ArrayAdapter, Utils) {
function CustomDataAdapter ($element, options) {
CustomDataAdapter.__super__.constructor.call(this, $element, options);
}
Utils.Extend(CustomDataAdapter, ArrayAdapter);
CustomDataAdapter.prototype.updateOptions = function (data) {
this.$element.find('option').remove();
this.addOptions(this.convertToOptions(data));
}
return CustomDataAdapter;
}
);
var customAdapter = $.fn.select2.amd.require('select2/data/customAdapter');
$(".select2-option").select2({
dataAdapter: customAdapter,
minimumResultsForSearch: -1,
data: data
});
function autoFillSelectedData() {
var selects = $('select.select2-option');
var selectedSelect2value = [];
for (var i = 0; i < selects.length; i++) {
selectedSelect2value.push(selects[i].value);
}
for (var i = 0; i < selects.length; i++) {
$.each(data, function(idx, val) {
if(val.id != "" && selectedSelect2value.indexOf(val.id) != -1 && val.id != selects[i].value) {
data[idx].disabled = true;
} else {
data[idx].disabled = false;
}
});
$('select#'+ selects[i].id).data('select2').dataAdapter.updateOptions(data);
$('select#'+ selects[i].id).val(selectedSelect2value[i]);
}
}
$("select").on("change", function () {
autoFillSelectedData();
});ul li {
list-style: none;
}
select {
width: 200px;
}
.m-b-20 {
margin-bottom: 20px;
