Question

我希望在第二次选择后隐藏表单下拉，因为它已经在之前选择了第二个组合框。目前我是这样的。

$data['year'] = NULL;

但我需要的是在选择下拉列表1后变量消失。

以下是我的代码。

控制器

function carbyyear() {
    $arrCaryear = $this->modelRegister->loadcaryear();

    $arrcaryear[''] = 'Please Select';
    foreach ($arrCaryear as $caryears) {
        $arrcaryear[$caryears->year] = $caryears->year;
    }

    $data['year'] = $arrcaryear;

    $this->load->view('abc',$data); 
}

function ajax_car_make() {

   if (isset($_POST) && isset($_POST['year'])) {

        $year = $_POST['year'];
        $arrMakes = $this->modelRegister->loadcarmake($year);

        //print_r($arrModels);
        $arrmakes[''] = 'Please Select';
        foreach ($arrMakes as $makes) {
            $arrmakes[$makes->make] = $makes->make;
        }

        print form_dropdown('make',$arrmakes);

        $data['year'] = NULL;

        $this->load->view('abc',$data); 

        } else {
        redirect('site');
    }   
}

function ajax_car_model() {

   if (isset($_POST) && isset($_POST['make'])) {

        $make = $_POST['make'];
        $arrModels = $this->modelRegister->loadmodelfrombrand($make);

        //print_r($arrModels);
        $arrmodels[''] = 'Please Select';
        foreach ($arrModels as $models) {
            $arrmodels[$models->model] = $models->model;
        }

        print form_dropdown('model',$arrmodels);
    } else {
        redirect('site');
    }   
}

无需在ajax响应中加载视图

function ajax_car_make()
{
   if (isset($_POST) && isset($_POST['year'])) {
    $year = $_POST['year'];
    $arrMakes = $this->modelRegister->loadcarmake($year);
    //print_r($arrModels);
    $arrmakes[''] = 'Please Select';
    foreach ($arrMakes as $makes) {
        $arrmakes[$makes->make] = $makes->make;
    }
    echo form_dropdown('make',$arrmakes);

    } else {
    echo false;
}

}

更改$('#makecombox select').change(function () {

到

$('body').on('change','#makecombox select',function () {

如何在codeigniter中隐藏form_dropdown
