路径文件中的
Route::get('griev_reg_form/assembly/{district_id}', 'GrievanceRegisterController@assembly');
在控制器中
public function assembly($id){
$assemblyConstituency = AssemblyConstituency::where('dis_code', '=', $id)->orderBy(3)->get();
$options = array();
foreach ($assemblyConstituency as $assembly) {
$options += array($assembly->ac_code => $assembly->ac_name);
}
return Response::json($options);
}
在视图文件
中 $("#district").change(function() {
$.getJSON("griev_reg_form/assembly/" + $("#district").val(), function(data) {
var $assembly = $("#ac_problem");
$assembly.empty();
$.each(data, function(index, value) {
$assembly.append('<option value="' + index +'">' + value + '</option>');
});
// $("#station_id").trigger("change"); /* trigger next drop down list not in the example */
});
});
当我更改选择框时,出现错误名称&#34; HTTP500:SERVER 错误 - 服务器遇到阻止的意外情况 它来自履行请求。&#34;
答案 0 :(得分:0)
这是因为我没有在控制器中添加响应
use Response;
