我有一个ajax调用,该调用获取动态数据并将其放置在select2中,如下所示:
$.ajax({
type: 'get',
url: '/api/?stuff='+c,
dataType: "json",
success: function (response) {
// If select2 is already defined, we destroy it and rebuild it with the new data
if(typeof $(".select2edit").data('select2') !== 'undefined') {
$(".select2edit").select2('destroy').select2({ data: response, width: '100%', closeOnSelect: false });
} else {
$(".select2edit").select2({ data: response, width: '100%', closeOnSelect: false });
}
}
});
我使用PHP创建响应,然后在发送响应之前将其转换为JSON:
$old_emplacement = '';
$results = array();
$i = -1;
while($array_campaign = tep_db_fetch_array($campaign)){
if ($array_campaign['name'] != $old_emplacement) {
$i++;
$results['results'][$i]['text'] = $array_campaign['name'];
$old_emplacement = $array_campaign['name'];
$c = 0;
}
$results['results'][$i]['children'][$c]['id'] = $array_campaign['id'];
$results['results'][$i]['children'][$c]['text'] = $array_campaign['c_name'];
$c++;
}
$results['pagination']["more"] = true;
因此产生以下JSON格式:
{
"results": [
{
"text": "Name 1",
"children" : [
{
"id": 1,
"text": "Text 1.1"
},
{
"id": 2,
"text": "Text 1.2"
}
]
},
{
"text": "Name 2",
"children" : [
{
"id": 1,
"text": "Text 2.1"
},
{
"id": 2,
"text": "Text 2.2"
}
]
}
],
"paginate": {
"more": true
}
}
当select2初始化并加载时,我得到一个No results found.
。而且我不知道为什么。就documentation来说,这是正确的格式,而other questions似乎可以证实。任何想法可能出在哪里?
还应注意,我的select2位于模式内部的表单中,这是html:
<select name="xx[]" id="edit-xx" name='xx' class="form-control select2edit" multiple>
</select>
答案 0 :(得分:1)
问题出在我的PHP代码生成的格式上。我将结果发布在这里,供尝试使用PHP生成select2 optgroup格式的任何人以及我自己的参考文献:
$old_emplacement = '';
$results = array();
$i = -1;
while($array_campaign = tep_db_fetch_array($campaign)){
if ($array_campaign['name'] != $old_emplacement) {
$i++;
$results[$i]['text'] = $array_campaign['name'];
$old_emplacement = $array_campaign['name'];
$c = 0;
}
$results[$i]['children'][$c]['id'] = $array_campaign['id'];
$results[$i]['children'][$c]['text'] = $array_campaign['c_name'];
if(in_array($array_campaign['id'], $campaigns_array)) {
$results[$i]['children'][$c]['selected'] = true;
}
$c++;
}
