这样写对不对

function getDate(url, type, param, sucCallBack) {
$.ajax({
url: url,
type: type,
data: param,
async: false,
success: sucCallBack,
error: function(xhr, ajaxOptions, thrownError){

    }  
});  

getDate("http://app.xindun.org/app/x222/redit/tracce", "get", {p1:"授信",p2:"京东",p3:"自研京东认证",rocess:"开始-曝光、开始-点击"},function(data){  

});  

}
