您的模型函数始终为return FALSE，因为您无法获取数据，并且在foreach() loop和model中的controller中使用了两次<?php function getvariance() { $this->db->select('name, IFNULL( quantity, 0 ) AS quantity'); $this->db->from('products'); $q= $this->db->get(); if ($q->num_rows() > 0) { return $q->result(); } else { return FALSE; } }数据你的代码错了。这将是

<强>模型

function getallvariance() {
    $this->load->model('products_model');// load your model
    $variance = $this->products_model->getvariance();
    if($variance){

    $output = '<tbody>';

    foreach ($variance as $row) {

        $output .= '<tr><td colspan="10" class=" sorting_1">' . $row->name . '</td></tr>';
    }
    $output .= '</tbody>';
    }else{
    $output="error";
    }

    echo $output;
}

 var goToProfileVar = String()
 var goToProfileVar2 = String()

func goToCell103(cell: mainCell)
{
    var goToCell103:mainCell? = cell as mainCell
    var indexPath: NSIndexPath  = self.resultsTable.indexPathForCell(goToCell103!)!

    goToProfileVar = cell.usernameLbl.text!
    goToProfileVar2 = cell.objectid.text!
           println("\(goToProfileVar) first.")
    println("\(goToProfileVar2) first.")



}


override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {



    if (segue.identifier == "goToProfile8") {
        var svc = segue.destinationViewController as! generalProfileLast;
        svc.dataPassed = goToProfileVar}

   else if (segue.identifier == "goToLikers1") {
        var svc = segue.destinationViewController as! likers;
        svc.dataPassed = goToProfileVar2}

    else if (segue.identifier == "goToComments1") {

    else if (segue.identifier == "goToComments2") {

        svc.dataPassed = goToProfileVar2}

      println("\(goToProfileVar) second.")
     println("\(goToProfileVar2) second.")

}

ajax没有显示HTML数据
