I see a syntax error in a closure definition. I've a JavaScript file, which has the following function. I'm loading the JavaScript file from another function and calling sampleFunction() from it. var sampleFuntion=function(obj){ //Statement here; }; But Firefox shows a syntax error for the first line, which is the function declaration/definition. I'm using Mozilla Firefox 29.0.1 on Windows 7. What is the actual error in the code? http://stackoverflow.com/questions/23904382/what-is-causing-the-syntax-error-i-see-in-firefox-developer-console javascript firefox firefox-developer-tools share|improve this question edited May 28 '14 at 20:31 Sebastian Zartner 7,29332956 asked May 28 '14 at 6:37 Rupam Datta 1,17611230 It's really hard to read the code in the screen shot. Can you post it as plain text? –Barmar May 28 '14 at 6:42 @Barmar Just edited. Please check now. –Rupam Datta May 28 '14 at 6:47 There is no syntax error, there... Are there any illegal characters around that function that aren't rendering? –Cerbrus May 28 '14 at 6:54 @Cerbrus Yes I also feel the same. There is no syntactical error. Also I rechecked for any illegal characters. –Rupam Datta May 28 '14 at 7:04 So, exactly what error is the console throwing? –Cerbrus May 28 '14 at 7:12 | show 1 more comment 3 Answers 3 active oldest votes up vote 2 down vote As the indicated script line doesn't contain any visual syntactical error, the problem is probably either an invisible illegal character within that line like e.g. a zero-width space. In that case just rewrite your function and ensure you replace everything up to the beginning of the file. Or the line number is incorrectly displayed within the console and the error is actually somewhere else. To test tha
in source code strings. When https://www.npmjs.com/package/syntax-error you type node src.js you get a friendly error report about exactly where the syntax error is. This module lets you check for syntax errors and report them in a similarly friendly format that wrapping a try/catch around Function() or syntax error vm.runInNewContext() doesn't get you. example var fs = require('fs');var check = require('syntax-error'); var file = __dirname + '/src.js';var src = fs.readFileSync(file); var err = check(src, file);if (err) { console.error('ERROR DETECTED' + Array(62).join('!')); console.error(err); console.error(Array(76).join('-'));} $ node check.jsERROR DETECTED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! /home/substack/projects/node-syntax-error/example/src.js:5 if (Array.isArray(x) res.push.apply(res, x); ^ParseError: Unexpected identifier--------------------------------------------------------------------------- methods var check = require('syntax-error') var err = check(src, file) Check the source code string src for syntax errors. Optionally you can specify a filename file that will show up in the output. If src javascript application error has a syntax error, return an error object err that can be printed or stringified. If there are no syntax errors in src, return undefined. err.toString() Return the long string description with a source snippet and a ^ under pointing exactly where the error was detected. attributes err.message short string description of the error type err.line line number of the error in the original source (indexing starts at 1) err.column column number of the error in the original source (indexing starts at 1) install With npm do: npm install syntax-error license MIT Private packages for the whole team It’s never been easier to manage developer teams with varying permissions and multiple projects.
