1.什么叫原生ajax?
2.这种json数据为什么是要用ajax遍历?
我概念上的模糊把,总感觉有数据交互的基本都用ajax,再说下为什么说原生,因为好多人都依赖像jq之类的库自带的ajax,我已经改过来了。就是把这个json数据遍历出来,前端数据交互这块很缺失
@model-zachary: json数据遍历交给遍历器不就行了吗?数据交互ajax的确用的多,但是处理json数据和数据交互是两个概念,不能混淆哦!
@~扎克伯格: 但是一般数据交互的数据格式都是json的,那是不是根据调用数据的性质来看,是否用ajax?再白一点就是虽然都是json数据,异步用的多,比如表单,这个就用ajax,其他可以用普通的遍历,把信息轮询一遍就可以了,也就是同步的,对吗?那么我萌生出一个疑问,他们的json写法都一样吗?谢谢大神
@model-zachary: 1.如果单纯说前后端数据交互的话,ajax传后台data主要是key-value形式的,但是返回的datatype有很多:xml、html、script、json、jsonp、text;
2、"再白一点就是虽然都是json数据,异步用的多,比如表单,这个就用ajax,其他可以用普通的遍历,把信息轮询一遍就可以了,也就是同步的,对吗?那么我萌生出一个疑问,他们的json写法都一样吗?"不知所云。
3.个人建议:不要只看概念去遐想,多动动手自然都会明白。不要管是不是原生,你先会用人家的再说。
@~扎克伯格: 恩,我通过node搭建了一个本地服务器,正在模拟后台进行数据的通信,以表单的为例,谢谢。
其实这不太明白,很想帮助你的 兄弟
有没有这个转换
function show(i) {
$.ajax({
type: "get",
url: "http://localhost:32629/api/Default/GetStr",
success: function (d) {
var p = jQuery.parseJSON(d);
$(p).each(function (i, obj) {
var r = "<tr><td>" + obj.Cid + "</td><td>" + obj.Cname + "</td><td>" + obj.Cprice + "</td><td>" + obj.Cnowprice + "</td><td>" + obj.Csonnum + "</td><td>" + obj.CpicUrl + "</td><td><a href='#' onclick=del(" + obj.Cid + ")>删除</a></td></tr>";
$("#aaa tbody").append(r);
})
}
})
}
看一楼大侠及我的回复,可能是我的概念搞混淆了,有些数据,非异步虽然也是json格式,可以用普通的遍历遍历除数据来,异步,比如表单就用ajax,虽然数据交互用ajax比较多,但也要结合需求,对不,然后我想问下大侠,那个json格式我怎么引进来,像引入js那样吗?
@model-zachary: /// <summary>
/// 获取数据
/// </summary>
/// <returns></returns>
public string Getstr()
{
List<QQQ> list=bll.show();
string Json = JsonConvert.SerializeObject(list, new DataSetConverter());
return Json;
}
转成json格式
没太明白你想干什么,
遍历不是很简单?for(var key in jsondata){}
