问题描述
控制器代码
$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);
我需要将此费率数组传递给Ajax
i need to pass this rates array to ajax
js代码
$.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>');
}
});
这将在标签上显示未定义。我无法获取从控制器传递来的数据。请帮忙吗?
this displays "undefined" on label. I can't get the data I have passed from controller. please help ?
推荐答案
- 取消注释
dataType:'JSON'
- 使用
echo
或set_output
将输出设置为json控制器 - 使用
rates.poor
或rates ['poor']
来自ajax
- Uncomment
dataType:'JSON'
- Set output as json with
echo
orset_output
from controller - Get item with
rates.poor
orrates['poor']
from ajax
控制器
public function post_url()
{
$rates = array();
$rates['poor'] = 10;
$rates['fair'] = 20;
$this->output->set_output(json_encode($rates));
}
Ajax
<script>
$.ajax({
type:'POST',
url:'POST_URL',
data:{'adID':adID},
dataType:'JSON',
success:function(rates){
$('#rate_val').html('<label>'+rates.poor+'</label>');
}
});
</script>
