我正在研究一个类项目,并希望在将新记录推送到数据库时在表中显示最后5个firebase记录。这在我的页面加载时正常工作,但随着更多记录的添加,表格继续增大,直到我刷新页面。有什么建议?谢谢!
productDatabase.ref().limitToLast(4).on("child_added", function(childsnapshot){
//Grabs key from childsnapshot and sets it to variable
var key = childsnapshot.key;
//Store everything in variables from the "child" data
var product = childsnapshot.val().ProductName;
var datestamp = childsnapshot.val().DateAdded;
//Uploading the results to the HTML table
$("#producttable > tbody").prepend("<tr><td>" + product + "</td><td>");
