[英]how to pass data from controller to jquery (Ajax) in codeigniter
控制器代碼
$rates['poor'] = 10;
$rates['fair'] = 20;
$this->load->view('search_result2', $rates);
//I have tried this in many ways but at least It executes the "success" in ajax file only with above way. other ways I have tried ex :-
//$this->output->set_output(json_encode($rates));
//echo json_encode($rates);
我需要將此費率數組傳遞給ajax
js代碼
$.ajax({
type:'POST',
url:'some url',
data:{'adID':adID},
//dataType:'JSON', // when I uncommented this it displays nothing. when commented it displays "undefined" on the label below i have created
success:function(rates){
$('#rate_val').html('<label>'+rates.poor+'</label>');
//I have tried this in many ways ex :-
// $('#rate_val').html('<label>'+rates['poor']+'</label>');
// $('#rate_val').html('<label>'+rates[0]+'</label>');
}
});
這會在標簽上顯示“未定義”。 我無法獲取從控制器傳遞來的數據。 請幫忙 ?
dataType:'JSON'
echo
或set_output
將輸出設置為json rates.poor
或rates['poor']
調節器
public function post_url()
{
$rates = array();
$rates['poor'] = 10;
$rates['fair'] = 20;
$this->output->set_output(json_encode($rates));
}
阿賈克斯
<script>
$.ajax({
type:'POST',
url:'POST_URL',
data:{'adID':adID},
dataType:'JSON',
success:function(rates){
$('#rate_val').html('<label>'+rates.poor+'</label>');
}
});
</script>
$data['a']='100';
$data['b']='200';
echo json_encode(array('success'=>$data));
jQuery的
<script>
$.ajax({
type:'POST',
url:'POST_URL',
data:{'adID':adID},
dataType:'JSON',
success:function(rates){
var data = jQuery.parseJSON('['+response+']');
$('#rate_val').html('<label>'+data.succcess.a+'</label><label>'+data.succcess.b+'</label>');
}
});
</script>
我相信它可以按您的意願執行。
