javascript - Debugging in the absence of debuggers -

some of users have reported inability log in mobile devices, such nintendo 3ds , psp web browsers. personally, have 3ds , been able reproduce issue... haven't clue how prepare it.

basically, can determine something wrong ajax code, causing form submit wrong place in wrong format.

now, in past had errors chrome (turned out adware) able debug using developer tools, looking @ error console, , getting result there.

but how has no such debugging tools? it's not game consoles, steam in-game browser unable log in apparently faulty ajax code.

what steps, if any, can take start getting bottom of these errors, without utilize of built-in debugging tools?

i had similar issue when had debug app wasn't working on ipad didn't have access mac debug with. without knowing browsers you've mentioned, i'm hoping provide value:

1) firebug lite: https://getfirebug.com/firebuglite javascript version of firefox's debugger can add together webpage, , while not total featured, can provide insight errors experiencing

2) ye olde debug statements. instead of alerting them, typically append them container styled overflow:scroll can read through them trace

good luck!
