ajax的另一种成功和失败回调函数

function engline(){
    var oldmsg = $(‘#lineso‘).val()
    if(oldmsg == null || oldmsg == ‘‘ || oldmsg == undefined){
        alert(‘input content Please‘)
    }else{
    //alert(oldmsg)
        $.ajax({
            url:"http://127.0.0.1:8888/engline",
            data : {‘msg‘:oldmsg},
            type : ‘GET‘,
            timeout : 3000,
            // 成功回调
            success: function(data){
                if(data){
                    $(‘#linest‘).val(data)
                }else{
                    alert(‘not result‘)
                }
            },    
            //失败回调
            error: function(XMLHttpRequest, textStatus, errorThrown){
                //查看错误信息
                alert(XMLHttpRequest.status);
                alert(XMLHttpRequest.readyState);
