onsubmit ajax 验证问题

[shangxuan]

function checkAddEmployee() {
    var employeeID = $('#employeeID').val();
    var employeeLastname = $('#employeeLastname').val();
    var employeeFirstname = $('#employeeFirstname').val();
    var employeeRemark = $('#employeeRemark').val();
    var status;
    if ((employeeID === '' ) || (employeeLastname === '') || (employeeLastname === '')) {
        layer.msg('这是最常用的吧');
        return false;
    }

    $.ajax({
        type: "POST",
        url: checkAddEmployeeUrl, 
        data: {employeeID:employeeID, employeeLastname:employeeLastname,employeeFirstname:employeeFirstname, employeeRemark:employeeRemark},
        dataType: "json",
        success: function(data){
            status= (data.status);
            if (status==-1)
            {
                alert("false");
                return false;
            }
            else {
                alert("true");
                return true;
            }

        }
    });


}

上面的代码在FF 上运行返回的结果是 FALSE ，而在 360浏览器和Chrome 中结果却是 true，这是为什么呢？

应该怎么写呢？

你这个函数只有false或者undefined返回。。success回调的return没有意义，

   function checkAddEmployee() {
        var employeeID = $('#employeeID').val();
        var employeeLastname = $('#employeeLastname').val();
        var employeeFirstname = $('#employeeFirstname').val();
        var employeeRemark = $('#employeeRemark').val();
        var status;
        if ((employeeID === '') || (employeeLastname === '') || (employeeLastname === '')) {
            layer.msg('这是最常用的吧');
            return false;
        }
        var result;/////////////////
        $.ajax({async:false,///////////
            type: "POST",
            url: checkAddEmployeeUrl,
            data: { employeeID: employeeID, employeeLastname: employeeLastname, employeeFirstname: employeeFirstname, employeeRemark: employeeRemark },
            dataType: "json",
            success: function (data) {
                status = (data.status);
                if (status == -1) {
                    alert("false");
                    result = false;//////////////////
                }
                else {
                    alert("true");
                    result = true;//////////////////
                }

            }
        });
        return result;/////////////////

    }
