Issue with input field

[Kuzyo]

Hi, everyone. Have some problem, don’t know how to solve. I’m writing small application where I check word on screen with word that was entered in input field, after checking every next word I clears input field with s.inputField.value = “”;, but then after checking I have additional empty string before the entered word:

"word" === " word" // false

How I can empty input field in another way. Thanks for advice.

You could use replace function on the string and get rid off white-space.

Something like this: http://codepen.io/alenabdula/pen/gtdnl

Thanks, @Alen works like a charm. I can’t find courage to learn RegExp

I have found second variant, to set input defaultValue to “”.

@Kuzyo I need to take on RegEx myself. I think it’s essential to any programmer.

I found http://regexpal.com to be helpful.

Thanks for advice. Cheers…

We had a weird issue on a clients project where we were looking for a word and would get weirdness involved. (Later turns out it was due to their clients copy and pasting from a Word document.) If the situation could use it (like it is not incredibly too sensitive and you can afford to be lax) then indexOf is a viable work around until you find a better solution.

What is the actual application? Are you using this as a challenge (e.g., like a captcha)? Or are you just looking for a particular word in a larger string of input?

If it’s a challenge, I would argue that it should fail.

“word” is not the same as ” word”.

If you’re just looking for a particular word, then use a regex. They’re not scary, and your case is very simple:

/\bword\b/.test( ' word' );

it happened
