Javascript-javascript error tolerance code

Javascript-javascript error tolerance code 1, symptom description
When an error occurs in javascript code execution on the page, the browser displays an error message.

2. Block js errors

Sometimes, after a project is launched, we need to make the browser ignore js errors. You can add the following code to the script tag, so the page will no longer display the error message.

Window. onerror = function () {return true ;}

Note: In this case, the error prompt is ignored. If a js error occurs, the following js execution will still be blocked.
