how to ignore errors in phantomjs

Question

I have a web crawler and I use phantomjs to parse pages, I want to get the html, but I always get this type of errors in the output before the html code

ReferenceError: Can't find variable: collapse_content_selector    http://staticloads.com/js/toggle.js?v=2013.10.04:135 TypeError: 'undefined' is not a function (evaluating '$('[placeholder]').placeholderLabel()') 

how can I stop that

The easiest way is to add an error handler to phantom.onerror or webpage.onerror. These callbacks are invoked when there is a JavaScript execution error (in the page or in your script).

page.onError = function(msg, trace) {     var msgStack = ['ERROR: ' + msg];     if (trace && trace.length) {         msgStack.push('TRACE:');         trace.forEach(function(t) {             msgStack.push(' -> ' + t.file + ': ' + t.line + (t.function ? ' (in function "' + t.function + '")' : ''));         });     }     // uncomment to log into the console      // console.error(msgStack.join('\n')); };
