jquery中For循环的问题

soft114 2017-02-26 10:49:05

想将下面程序中红色字体部分的xDatas值改成for循环（for (var i=1206;i<1278;i++）{ }），试了一直没成功，程序无法运行?
新人请指教，谢谢

var xDatas = []; for(var i = 1;i<100;i++) { xDatas.push(i); }

var xDatas = []; for(int i = 1;i<100;i++) { xDatas.push("i"); } 客户端这样写好像不行

我只在本机上实现，不在服务器上使用的，请教如何写呢？

你要搞清楚：<%%>里面的代码一般都是服务器端的代码，如jsp,asp等，服务器端的语言和客户端的js不一样的，要使用服务器端的数据，你可以类似这样 var xDatas=[]; <% for(int i = 1;i<100;i++){ %> xDatas.push("<%=%>"); <% } %> 或者ajax请求得到
