使用select2插件，如果后台查找没有记录，不能返回null，要返回一个空数组，不然会报错：data is null
空数组形式为（firefox调试输出）：{"items":[],"total_count":0}
完整使用记录如下：
前台html标记：
<div class="form-group col-md-6"> <label for="supplier">供应商</label> <select name="supplier" id="supplier" class="form-control" > </select> </div>
前台JS
$(‘#supplier‘).select2({
theme: "bootstrap",
placeholder: "选择供应商",
allowClear: true,
ajax:{
url:"{:U(‘Supplier/getvalidSupplier‘)}",
dataType:"json",
delay:200,
data:function(params){
return {
q:params.term,
page:params.page
}
},
processResults:function(data,params){
params.page = params.page || 1;
return {
results: data.items,
pagination: {
more: (params.page * 10) < data.total_count
}
};
},
cache: false
},
//minimumInputLength: 1,
});
后台PHP TP3.22
public function getvalidSupplier(){ $q=I("q"); $page=intval(I("page"))<1?1:I("page"); $map[‘supplier|contractor|co_addr‘] = array(‘like‘,‘%‘.$q.‘%‘); $map[‘status‘]=1; $pageParas[‘pageLength‘]=10; $pageParas[‘pageStart‘]=($page-1)*10; $pageParas[‘orderField‘]=‘supplier‘; $arr = $this->getPageData($map,null,true,null,$pageParas); $i=0; $arr2=array();//重点在这里 foreach ($arr as $key => $row) { $arr2[]=array("id"=>$row[id],"text"=>$row[‘supplier‘]); $i++; } $this->ajaxReturn(array(‘items‘=>$arr2,"total_count"=>$i)); }
