index.html 引入标签:

<script src="./js/seajs.min.js"> </script>
<script>
seajs.config({
alias: {
"jquery": "./../js/jquery-3.2.1.min.js"
}
})
seajs.use('./mainjs/seajstest.js');
</script>

路径也正确然而没卵用,看了几遍才知道,jquery要用cmd 语法包一层的: define(function (require, exports, module) { //jquery 源码直接复制进去

})

what a fuck
