Ajax 包装方法,包含刷新

记录一个通用方法,包含刷新

//异步ajax请求，默认POST方法
formTool.ajaxAsync = function(json,url,method,func){
    url =  this.contextPath + url;
    if(this.isNull(method)){
        method = "POST";
    }else{
        method = method.toUpperCase();
    }
    var xhr = $.ajax({
        async: true,
        type: method,
        url: url,
		timeout:40000,
        data: json,
        beforeSend: function(request) {
        	//请求之前调用的函数
            layer.load(0, {
                shade: [0.2,'#fff'] //0.1透明度的白色背景
            });
        },
        error: function(result) {
            layer.closeAll('loading');
            if(result.status == 401){
                layer.msg('登陆认证失败，请重新登陆!');
                window.location.href = formTool.isPc == true ? formTool.pcLogin : formTool.mobileLogin;
            }else{
                layer.msg('服务器异步请求失败!', {icon: 2, time: 2000});
            }
        },
        success: function(result) {
            layer.closeAll('loading');
            if(typeof func == "function"){
                func(result);
            }
        },complete:function (XMLHttpRequest,status) {
            layer.closeAll('loading');
            if(status=='timeout'){
                layer.msg('请求超时，请重试', {icon: 2, time: 2000});
                xhr.abort()// 超时后中断请求
            }
        }
    });
};

　　调用方法:

 //测试
            formTool.ajaxAsync({"sid": sid,"publishTime":pass}
                ,"/working/pulishYearSynchroData"
                ,"POST",function(result){
                    //回调
                    if (result.code == 0) {
                        layer.msg(result.msg);
                        search();
                    } else {
                        layer.msg(result.msg, {icon: 2});
                    }
                    layer.close(indexel);
            });
