Syntax error: Illegal return statement in JavaScript

久未见 提交于 2019-12-03 09:17:30
I am getting a really weird JavaScript error when I run this code: <script type = 'text/javascript'> var ask = confirm('".$message."'); if (ask == false) { return false; } else { return true; } </script> In the JavaScript console it says: Syntax Error: Illegal return statement It occurs at return true; and return false; (I am echoing this javascript from a php function; the $message variable is one of the php parameters) What is wrong with my code? return only makes sense inside a function. There is no function in your code. Also, your code is worthy if the Department of Redundancy Department.

I'm running parallel processing in Python on Windows. Here's my code: from joblib import Parallel, delayed def f(x): return sqrt(x) if __name__ == '__main__': a = Parallel(n_jobs=2)(delayed(f)(i) for i in range(10)) Here's the error message: Process PoolWorker-2: Process PoolWorker-1: Traceback (most recent call last): File "C:\Users\yoyo__000.BIGBLACK\AppData\Local\Enthought\Canopy\App\appdata\canopy-1.5.4.3105.win-x86_64\lib\multiprocessing\process.py", line 258, in _bootstrap self.run() File "C:\Users\yoyo__000.BIGBLACK\AppData\Local\Enthought\Canopy\App\appdata\canopy-1.5.4.3105.win-x86_64

SQLCMD utility from BAT file - how to return ERRORLEVEL in case of syntax error

爷,独闯天下 提交于 2019-12-03 07:16:44
How can I get %ERRORLEVEL% from SQLCMD utility when some of .sql files contains syntax error? These files create stored procedures. They don't invoke "raiseerror", but they can conatin syntax error and I need to terminate the process. But it always returns %ERRORLEVEL% as 0. I tried use -b, -V and -m (and their combinations), but nothing worked for me as expected. Here's the code fragment of my BAT file. REM process all sql files in "SQL\scripts" folder and subfolders FOR /R "SQL\scripts" %%G IN (*.sql) DO ( sqlcmd -d %1 -S %2 -U %3 -P %4 -i "%%G" -b -V 1 echo %ERRORLEVEL% IF %ERRORLEVEL% NEQ

Why does 00.0 cause a syntax error?

问题 This is weird. This is what happens at the JavaScript console in Chrome (version 42.0.2311.135, 64-bit). > 0 < 0 > 00 < 0 > 0.0 < 0 > 00.0 X Uncaught > SyntaxError: Unexpected number Firefox 37.0.2 does the same, although its error message is: SyntaxError: missing ; before statement There's probably some technical explanation regarding the way JavaScript parses numbers, and perhaps it can only happen when tinkering at the console prompt, but it still seems wrong. Why does it do that? 回答1: The

Is there a Jade template syntax checker/validator?

这一生的挚爱 提交于 2019-12-03 06:02:39
I have some syntax errors in my Jade templates. Are there any tools that can help me debug? Found it. Use jade [fileName].jade to debug your Jade template. You can install the Jade tool with npm install jade --global . Adding this here because I still had to google. npm i -g pug-lint NOTE: jade has changed its name to pug web storm is a better tool for jade development ,it idents and corrects jade files 来源: https://stackoverflow.com/questions/14173144/is-there-a-jade-template-syntax-checker-validator

Dict merge in a dict comprehension

自闭症网瘾萝莉.ら 提交于 2019-12-03 05:55:41
In python 3.5, we can merge dicts by using double-splat unpacking >>> d1 = {1: 'one', 2: 'two'} >>> d2 = {3: 'three'} >>> {**d1, **d2} {1: 'one', 2: 'two', 3: 'three'} Cool. It doesn't seem to generalise to dynamic use cases, though: >>> ds = [d1, d2] >>> {**d for d in ds} SyntaxError: dict unpacking cannot be used in dict comprehension Instead we have to do reduce(lambda x,y: {**x, **y}, ds, {}) , which seems a lot uglier. Why the "one obvious way to do it" is not allowed by the parser, when there doesn't seem to be any ambiguity in that expression? It's not exactly an answer to your question

How can I check JavaScript code for syntax errors ONLY from the command line?

寵の児 提交于 2019-12-03 05:26:15
问题 JavaScript programs can be checked for errors in IDEs or using online web apps but I'm looking for a way to detect syntax errors alone . I've tried JSLint and JSHint and looked at their options but I haven't been able to find a combination that would exclude warnings and just shows the syntax errors. How do I check JavaScript code for syntax errors only from the command line? 回答1: I use acorn: $ acorn --silent tests/files/js-error.js; echo $? Unexpected token (1:14) 1 $ acorn --silent tests

Why does the expression (true == true == true) produce a syntax error?

和自甴很熟 提交于 2019-12-03 05:22:02
问题 Ruby : true == true == true syntax error, unexpected tEQ vs. JavaScript : true == true == true // => true vs. C : 1 == 1 == 1 // => 1 回答1: Association direction, which controls the order of operators having their arguments evaluated, is not defined for the == method, same as for === , != , =~ and <=> methods as well (all of which have the same precedence and form a separate precedence group exclusively). Documentation Thus evaluation order in case of multiple operators from the list mentioned

Syntax Error: Not a Chance

我们两清 提交于 2019-12-03 01:47:02
问题 I tried executed the following code in the python IDLE from __future__ import braces And I got the following error: SyntaxError: not a chance What does the above error mean? 回答1: You have found an easter egg in Python. It is a joke. It means that delimiting blocks by braces instead of indentation will never be implemented. Normally , imports from the special __future__ module enable features that are backwards-incompatible, such as the print() function, or true division. So the line from _
