Question

I have one line of code that is throwing an error that I don’t care about. I need to hide it from the console. I don’t want to use a custom error handler and return false, because I want to see all other errors.

I’ve tried a try / catch, but the error still shows up in the console:

try{
    //the erroneous line of code
}catch(err){ }

I’ve also tried fiddling window.onerror right before the erroneous line, and fiddling it back right after, and the error still shows up in this case as well:

window.onerror = function(){ return false; }
//erroneous line of code
window.onerror = function(){ return true; }

Any help would be appreciated.

Answer 1

try catch is the one to use

b=a; // gives an error in the console
try {
  a = x; // does NOT give an error in the console
}
catch(e) {
  document.getElementById('error').innerHTML='ERROR: '+e.message;
}  

I only get

a is not defined

in the console in my fiddle

I do not get the SECOND error in the console. Not even after commenting out the first error just in case it possibly blocked further processing.
