How to remove all HTML from JSON Response
Question
I use json for php javascript . But when javascript call back , it show HTML Every Where .
Code:
$('#buyNow').click(function(){
$('#loading').html('<i class="fa fa-spinner fa-pulse fa-3x fa-fw margin-bottom"></i>');
$('#group-pay').hide();
var nameproduct = $('#myModalLabel1').text();
$.get(base_url+"dashboard/shop",{ buy: idProduct },function(data){
var obj = $.parseJSON(data);
alert(data);
if(obj.Code == 200){
$('#loading').html('<div class="alert alert-success">Success <strong>'+nameproduct+'</strong></div>');
$('#group-pay').show();
}else{
$('#loading').html('<div class="alert alert-danger">Error</div>');
$('#group-pay').show();
}
});
});
And my PHP:
$vatpham = $_REQUEST['buy'];
if($vatpham >= 400 && $vatpham <= 609)
{
$json = array("Code" => "200");
echo json_encode($json);
}
Error Reponse Show is:

In codeigniter controller class, create one method to only have a code producing json and returning it, and never load any view from that method :
// dashboard/shop
public function shop () {
// in this method should only returned jSON respond
// instead of any view
$vatpham = $_REQUEST['buy'];
if($vatpham >= 400 && $vatpham <= 609)
{
$json = array("Code" => "200");
echo json_encode($json); //<--- only return this
}
// remove below code if have, or create another method to only return
// json respond
$this->load->view('somefilename', $data);
}
Or if you cant remove that, you need to replace all the html content and leave behind JSON, but this solution are not wise :
$.get(base_url+"dashboard/shop",{ buy: idProduct },function(data){
// remove all the HTML content that start with `<` till the end
var obj = JSON.parse( data.replace( /\<.+/ig,'') ); // or $.parseJSON( data.replace( /\<.+/ig,'') );
