小程序如何使用linq.js,在小程序中引用linq.js后运行报错,第1张

我没用过linq.js,但我可以肯定的是这种前端框架肯定是不能用于小程序的。小程序虽然是基于浏览器内核的,但它的脚本是绕过网页DOM结构直接操作内核的,也就是说你在小程序中看到的界面并不是网页,所以这种操作网页DOM的js脚本都是不能用于小程序的

首先学习html基础,然后学习c#的语法( 包括基础语法和进阶语法,比如linq,反射等等framework3.5以后的新特性),.aspx的生命周期过程等等,刚开始可以拖控件开发,以后,可以自定义控件,在以后,学习css,学习js,掌握一个js库,比如jquery或者Ext,在以后,学习html5和css3,有个天轰穿的入门视频不错,楼主可以搜索来看

我的一个GridView操作文件,数据源是实体LIST,删改查功能都有了,你参考下
