获取文本而不是选择元素

Question

有没有办法获取文本而不是选择元素上的值并创建存储以将其传递到$ this-＆gt; input-＆gt; post（'cols'）？

这是我的控制器

public function index() {
    $data['title'] = 'Reports';
    $data['content'] = 'reports';
    $this->load->view('layout/admin_layout', $data);
}

public function gen_custom_rep() {

    $c_dt_st = explode("/", $this->input->post('c_dt_st'));
    $c_dt_end = explode("/", $this->input->post('c_dt_end'));
    $dt_st = $c_dt_st[2] . '-' . $c_dt_st[0] . '-' . $c_dt_st[1];
    $dt_end = $c_dt_end[2] . '-' . $c_dt_end[0] . '-' . $c_dt_end[1];
    $ref = $this->input->post('list_of');
    $oprtn = $this->input->post('oprtn');
    $val = $this->input->post('val');
    $columns = array("$ref");
    $qry = "SELECT DISTINCT($ref) as ref_col";
    foreach ($this->input->post('cols') as $col_nm) {
        $col_res = $this->m_reports->exec_custom("SELECT DISTINCT($col_nm) as col_key FROM tbl_proj_details");
        foreach ($col_res as $c_res) {
            array_push($columns, $c_res->col_key);
            $qry = $qry . ",(SELECT $oprtn($val) FROM tbl_proj_details WHERE $ref = ref_col AND $col_nm='$c_res->col_key' AND (dt_approved BETWEEN '$dt_st' AND '$dt_end')) as col_$col_num";
            $col_num = $col_num + 1;
        }
    }
    $qry = $qry . " FROM tbl_proj_details";
    $data['res'] = $this->m_reports->exec_custom($qry);

在我的视图页面中。

下面。我刚编辑了我的帖子。 ：D有没有人知道如何从选定的选项中获取文本并将其放在变量中以将其传递到输入帖子上，以便我可以将其用作生成的Excel文件的列名

Answer 1

您可以使用

选择所选选项的文本

$('#cols').change(function(){ var selectedOptions = []; $('#cols option:selected').each(function(){ selectedOptions.push($(this).text()); }); alert(selectedOptions); });

以下是示例

＆＃13;

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="cols" id="cols" multiple>
           <option value"latest_update"> Lates Update</option>
           <option value"spin"> SPIN</option>
           <option value"status"> Status</option>
    </select>

＆＃13;

get '/' do
  template_output = erb :template
  "Here is the output from template: #{template_output}"
end

＆＃13;

＆＃13;
