JQ's ajax package

JQ's ajax encapsulation 
function Ajax(opt){
     var isdefult=opt.isdefult||"need"; // Determine whether this function is needed to judge, or to judge after the data returned by the page request is returned 
    $.ajax({
        url: 'http://haha/'+opt.url, // The path of the data interface 
        dataType:'json' ,
        type: opt.type ||"get", // The default method of the request is get 
        data:opt.param||"", // The default parameter of the request is empty 
        async:opt.async|| true , // Whether it is Asynchronous, the default is asynchronous 
        timeout: 10000 ,
        success: function (res) {
             
            if (isdefult=="need"){ // Determine whether this function is needed to judge, or after the data requested by the page comes back 
                if (res.code==0){ // According to Judging by the return of your own project 
                    opt.successBack instanceof Function&&opt.successBack(res.data); // successful function, see the value of your own project 
                }
                 else {
                    console.log(res.msg)
                }
            }
            else
            {
                opt.successBack instanceof Function&&opt.successBack(res);
            }
     },
        error: function(xhr, type, errorThrown){
            console.log(JSON.stringify(xhr));
            console.log(type);
            console.log(errorThrown);
        }
    });
}
See what you like. You can choose to extend it to jquery, or it can be a function.
