控制台不必要的错误消息是否会减慢网页速度?

问题描述

我正在使用 Handsontable 在我的网页中显示一些表格并且它工作正常,但是随着时间的推移,当客户端将页面挂起时,页面会累积错误,例如

(我无法上传图片,但消息是这样的)

387 handsontable.full.min.js:34 Uncaught TypeError: Cannot read property 'querySelector' of null
    at t.overlayContainsElement (handsontable.full.min.js:34)
    at n.value (handsontable.full.min.js:34)
    at n.value (handsontable.full.min.js:40)
    at n.value (handsontable.full.min.js:40)
    at HTMLdivelement.<anonymous> (handsontable.full.min.js:40)
    at HTMLdivelement.i (handsontable.full.min.js:34)

它是否会导致页面变得比初始慢?

这是我的代码中handsontable的部分


function table(data){
try {
    document.getElementById('data_view').innerHTML = null;
    const container = document.getElementById('data_view');
    hot = new Handsontable(container,{
    licenseKey: 'non-commercial-and-evaluation',data: data,//rowHeaders: true,colHeaders: 
 ['Area','WorkStation','Stepname','Commit','TechNode','Moves','WIP','Running','Hold','MTAS','Delta to Commit','Remarks','Delta to Commit'],//editor: false,columns: function(column) {
    var columnMeta = {};
    if (column === 0) {
      columnMeta.data = 'AreaName';
    } else if (column === 1) {
      columnMeta.data = 'workstation';

通常这不是网站性能的问题,只是它不美观或不专业。您应该尝试修复错误或寻找其他解决方案。
