function findLongestWord(str) {

  var longest = 0;
  var changedStr = str.split(' ');

for(var i = 0; i < str.length; i++){

}  
 console.log(changedStr[i].length);
}
findLongestWord("hel00 yoiii cool");

VM168:9 Uncaught TypeError: Cannot read property 'length' of undefined
at findLongestWord (<anonymous>:9:28)
at <anonymous>:11:1

Why am i getting the message on the bottom?

i am using the console in chrome to type in the function

Brad

@bradtaniguchi

@zootechdrum Your console log uses i, but its outside of the for loop

so there is no i, thus i is undefined

Idk about your error tho, seems like its related to something else. Something might not be coming as expected ( can you printout str before the for loop?)

Cesar Gomez

@zootechdrum

the main thing i want to do is get the length of the index that var i is on. For whatever reason I get an error saying cant get length of unde

@bradtaniguchi

Brad

@bradtaniguchi

Oh ok yea

Cesar Gomez

@zootechdrum

I tried this too

function findLongestWord(str) {

var longest = 0;
var changedStr = str.split(' ');

for(var i = 0; i < str.length; i++){
changedStr[i].length;
}

}

findLongestWord("hel00 yoiii cool");

Brad

@bradtaniguchi

My original mention of this code: changedStr[i].length doesnt work

I think your string.length is off by 1

Cesar Gomez

@zootechdrum

function findLongestWord(str) {

  var longest = 0;
  var changedStr = str.split(' ');

for(var i = 0; i < str.length; i++){
  changedStr[i].length;
}  

}

findLongestWord("hel00 yoiii cool");

let me see

Brad

@bradtaniguchi

if your string was coolthe length is 4, but if you do changeString[4] its undefined, as thats the 5th spot

Cesar Gomez

@zootechdrum

i think you might be on to something lo

Brad

@bradtaniguchi

But then i < str.length wont work :/

so I might be wrong :/

Just double checked, it should work, BUT I noticed your trying to update the changedStr variable.

That's incorrect, since if you provide just 1 word, but your checking against the length of the string it will break

so your example has changedStr = ['hel00', 'yoii', 'cool']; so its length is just 3

but the str length is like 15 or so

Hello, does anyone know how to make a checkbox dropdown menu and checkbox dropdown submenu alltogether? I'm having a difficult time. :(

Brad

@bradtaniguchi

@UnorthodoxThing Are you using a framework or trying to do this from scratch?

can someone help me ... i screwed up again .. i'm trying to get the "Search Wikipedia" button to the right of the form and put them in the center of the page under the title..... :worried:

grid system is confusing me :anguished:

Caroline Rozali

@hyfyline

@bradtaniguchi What do you mean by a 'framework'? I think mostly from scratch. I tried learning from a video online. I also be CSS and HTML only. This is what I've got so far... https://codepen.io/UnorthodoxThing/pen/oENvEX

Brad

@bradtaniguchi

@UnorthodoxThing Well if you mean you want to make a dropdown with checkboxes in it I think you will need to create it from scratch using JS and css

If you don't or cant use JS for this, then you probably have to rely more on what html provides ( they have a multiselect option for select)

@JoEeeezy_twitter let me see

i changed it since @bradtaniguchi i ended up copying this code and modifying it https://i.imgur.com/XgEaWb3.png

i'm not sure if it works because of the form-inline class but i could've swore i've tried that before...

Brad

@bradtaniguchi

If the form tag scares you, you can always change it to something else.

JoEezy

@JoEeeezy_twitter

i think it's just that i'm confusing it with the input tag

@jdbrann

@khaduch Wow that was some great feedback and things I can look up and read up on more. I kinda feel I rushed in to making the page and maybe bit off more than I can chew without seeking out more training first but your feedback did a great job of highlighting some of the misses (I took notes down to look up your suggestions/"how to do...")that will help me grow and that is what I needed! Thanks!!!

Brad

@bradtaniguchi

@JoEeeezy_twitter Just remember the form tag will try to "submit" to a backend if the user hits enter, or clicks on a button that isn't type="button"

JoEezy

@JoEeeezy_twitter

@bradtaniguchi thanks , i was wondering why the button kept refreshing the page even though i hadn't set it up in js yet :smile:

// Twitter Button    
    $("#twitter").on("click", function() {
        $("#tweetit").attr("href", 'https://twitter.com/intent/tweet?text=' + "\"" + 
        $("#quotetext").text() + "\" " + " -" + $("#author").text());
