我目前正遇到一个问题,我的select2插件有时显示上次选择的选择框的结果。另外,当我第一次点击选择框或输入太快时,我也会得到g.results为null。我的代码如下。
window.currentField = ""; //current product field data
window.currentCategory = ""; //current product category data
//lets get some data from the hidden input for providing suggestions via ajax
$(".suggestive-entry").live('click',function() {
//alert("click called");
//alert("test");
window.currentField = $(this).siblings('input:hidden').attr('data-field'); //get the field attribute
// alert(window.currentField);
window.currentCategory = $(this).siblings('input:hidden').attr('data-category'); //get the category attribute
});
//formats select2 returned option
function format(item) { return item.term; };
//used for suggestive search fields
$(".suggestive-entry").select2({
createSearchChoice:function(term, data) { if ($(data).filter(function() { return this.term.localeCompare(term)===0; }).length===0) { return {id:term, term:term};} },
initSelection : function (element, callback) {
var data = {id: element.val(), term: element.val()};
callback(data);
},
multiple: false,
ajax: {
url: "includes/ajax/map-fields.php",
dataType: 'json',
data: function (term, page) {
//alert("suggestive called");
return {
q: term,
field: window.currentField,
ptype: window.currentCategory
};
},
results: function (data, page) {
return { results: data };
}
},
formatSelection: format,
formatResult: format
});
非常感谢任何帮助。

尝试为你的隐藏字段提供id,做这样的事情
data: function (term, page) {
//alert("suggestive called");
var data_field = $('#someId').attr('data-field');
var data_category = $('#someId').attr('data-category');
return {
q: term,
field: data_field,
ptype: data_category
};
}
