我正在使用select2版本3.5.4。 我希望并排有两个select2下拉菜单。当页面第一次加载时,一个select2下拉列表有数据,而第二个select2下拉列表为空。一旦用户点击第一个select2下拉列表中的一个条目/选项,就应该对服务器进行ajax调用,并且应该使用ajax响应数据填充第二个select2下拉列表。我无法实现它。每当我尝试填充第二个下拉列表时,我会得到像
这样的错误Option 'data' is not allowed for Select2 when attached to a <select> element
Option 'ajax' is not allowed for Select2 when attached to a <select> element
我的代码就像,
HTML: -
<div class="form-group">
<label class="col-md-4 control-label" for="folderSelect">Files & Folders</label>
<div class="col-md-5">
<div class="select2-wrapper">
<select class="form-control select2" id="folderSelect" name="folderSelect">
<option></option>
<option th:each="folder : ${folders}" th:value="${folder}" th:text="${folder}"/>
</select>
</div>
</div>
<div class="col-md-5">
<div class="select2-wrapper">
<select class="form-control select2" id="fileSelect" name="fileSelect">
<option></option>
<option th:each="file: ${files}" th:value="${file}" th:text="${file}"/>
</select>
</div>
</div>
</div>
JS: -
$('#folderSelect').on("select2-selecting", function(e) {
var value = $(e.currentTarget).find("option:selected").val();
var data = null;
$.ajax({url: "test?value=" + value, success: function(result){
data = result;
return result;
}});
$("#fileSelect").select2({
/* ajax: { // Tried but didn't work
dataType: 'json',
url: 'test',
results: function (data) {
return {results: data};
}
}*/
/*data: function() { //Tried but didn't work
$.ajax({url: "test", success: function(data){
return data;
}});
}*/
});
//Tried but didn't work <br>
$("#fileSelect").select2('destroy').empty().select2({data: data});
});
