Question

alert("Your ID is"+randomString());



if ($('#txtAgree').is(':checked')) {
        alert("You have succesfully submitted the form Thank You:");
        var params = $("#payuForm").serialize();

        $.ajax({
            type: "POST",
            url: "admin/api/process_pay.php",
            data: params,
            dataType: "json",
            success: function(response) {
                //alert("yes");
                alert("Your ID is"+randomString());
                refreshAdd();

            }
        });
    } else {
        alert("Please Select terms and conditions:");
        return false;
    }




    // return true;
} catch (ex) {
    alert("Error -> : " + ex.message);
}
});




function randomString() {
var chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz";
var string_length = 8;
var randomstring = '';
for (var i=0; i<string_length; i++) {
    var rnum = Math.floor(Math.random() * chars.length);
    randomstring += chars.substring(rnum,rnum+1);
}
document.randform.randomfield.value = randomstring;
}

这里我通过警报调用javascript函数。我想要每个表单提交的唯一键，并通过ajax调用执行表单。以上是我的代码。在这里，我通过警报调用javascript函数。我想要每个表单提交的唯一键，并通过ajax调用执行表单。以上是我的代码。

function randomString() {
var chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz";
var string_length = 8;
var randomstring = '';
for (var i=0; i<string_length; i++) {
    var rnum = Math.floor(Math.random() * chars.length);
    randomstring += chars.substring(rnum,rnum+1);
}

return randomstring; //was missing in your code
}

您没有从函数

返回randomstring
