推荐答案
在您的jsfile.js文件中，请更正我在以下代码中作为注释提及的以下几点.
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", // Second add quotes on the value.
},
success:function(response) {
document.getElementById("disp").innerHTML =response;
},
error:function(){
alert("error");
}
});
}
