javascript - 怎样才能点击按钮是获取到该条新闻的数据id值，并让新闻里的字段以内容方式在单个页面显示出来

Question

新闻列表和查看代码：

exports.list = (req,res,next) => {
    let sql = "select * from exihibition";
    util.getConn().queryAsync(sql).then((result) => {
        res.render("admin/exihibitionlist.html",{exihibitions:result});
    }).catch((err) => {
        res.send("error");
    });
}

exports.show = (req,res,next) => {
    let sql = "select * from exihibition where id = ?";
    util.getConn().queryAsync(sql,这里要怎么写才能取到该条新闻的id值).then((result) => { 
        res.render("admin/exihibitionshow.html",{exihibitions:result});
    }).catch((err) => {
        res.send("error");
    });
    
}


数据传输代码：

var exihibitionlist = {

url : "/exihibition/list",
class : "page",
render : function(){
    return $_ajax({
        url : "/exihibition/list",
        type : "get"
    });
}

}
var exihibitionshow = {

url : "/exihibition/show",
class : "page",
render : function(){
    return $_ajax({
        url : "/exihibition/show",
        type : "get"
    });
}

}
