GoodsMange.js:
$(function(){
$(".layui-nav-child").on("click", "dd", function(){
var sId = $(this).data("id"); //獲取data-id的值
window.location.hash = sId; //設置錨點
loadInner(sId);
});
function loadInner(sId){
var sId = window.location.hash;
var pathn, i;
switch(sId){
case "#addGoods": pathn = "addGoods.jsp"; i = 1; break;
case "#delGoods": pathn = "deleteGoods.jsp"; i = 1; break;
case "#updGoods": pathn = "updateGoods.jsp"; i = 1; break;
default: pathn = "empty.jsp"; i = 0; break;
}
$("#content").load(pathn); //加載相對應的內容
var sId = window.location.hash;
}
loadInner(sId);
$(".layui-nav-child dd").eq(i).addClass("current").siblings().removeClass("current"); //當前列表高亮
});
然后大家必須要注意，因為是在div標簽中加載其他jsp中的內容，所以要加載的jsp不能有和父頁面相同的標簽。比如<html> <head><body>等等。
addGoods.jsp:

<script>
function showImg(){

var re = new FileReader();
re.readAsDataURL(file);
re.onload = function(re){

}
}
</script>
在script標簽加上：
form.render();
即可。
每一次加載該頁面，js都會進行一次渲染，這樣的話就不會出現js渲染失效或者js加載失敗等問題。
弄了一下午才弄出來的，如果對入坑的小伙伴有幫助就關注一下就好啦。
