In your jsfile.js file, please correct the following points which I have mentioned as comments on the following code.
function cart(id1)
{
var id=id1;
alert("enterd "+id);
document.getElementById("disp").innerHTML ="hi";
$.ajax({
url:"/add.php ",
method:"POST", //First change type to method here
data:{
item_id: id,
},
success:function(response) {
document.getElementById("disp").innerHTML =response;
},
error:function(){
alert("error");
}
});
}
Change it and try
type:"POST" -> method: "POST"
If your jquery version is >= 1.5 use it this way.
$.ajax({
url: "add.php",
method: "POST",
data: { item_id: id},
}).done(function(response) {
......
}).fail(function( jqXHR, textStatus ) {
......
});
Load Jquery Before your JS file.
