试试这个   这对我有用

function discount(){
alert('hi');
 $.ajax({
        url: "<?php echo base_url();  ?>/index.php/home/give_form",
        dataType: 'json',
        type: "POST",
        data: {cityy: city},
        success: function(response) {
            alert(response)
        },
    });
}

Answer 2

更改您的ajax网址

url: "<?php echo base_url();  ?>" + "index.php/home/give_form"

到

 url: <?php echo base_url();  ?> + "index.php/home/give_form"

Answer 3

试试这个

function discount(){
alert('hi');
var base_url = window.location.origin;
jQuery.ajax({
   url: base_url + "/index.php/home/give_form",
   type: "post",
   data: "cityy="+city,
   success: function(response) {
   alert(response);
 }
});
