hey guys why isnt the sort being applied to the last array
``````
function largestOfFour(arr) {
var iteration = 0;
var largestNum = 0;
var ans = [];

for(var i = 0;i <= arr.length-1;i++){
arr[i].sort();
ans.push(arr[i]);
}

return ans;
}

largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);``````

@zootechdrum it does, that is the way `sort()` work. you have to define `sort(function (a, b) { return a > b}` to get it properly sort.

@gauravsinghaec `var data = json;` is redundant. You could just use `json`, or change the parameter name to `data`. No need for the extra variable.

</ul>
<input name="searchTxt" type="text" id="searchText">
<button onclick="list()">Press</button>

</html>``````
``````function list() {
var ul = document.getElementById("list");
var li = document.createElement("li");
var text = document.getElementById("searchText").value;
var crea = li.appendChild(document.createTextNode(text));
ul.appendChild(li);
}

function deleteQ() {

var parent = document.getElementById('list');

}

};``````

Im trying to delete the li created element ....

Sweet Coding :)
@SweetCodingInc
Apr 04 2018 07:32
@JavierPons In what order you want them deleted?
It will only work for the first time
once you delete the default li, it will not work as there will be no element with `id="element1"`
Javier Pons
@JavierPons
Apr 04 2018 07:37
@SweetCodingInc I want to delete li after I have created a new one
Sweet Coding :)
@SweetCodingInc
Apr 04 2018 07:42
so you want to have only 1 li at any given point in time?
Sorry, I'm not able to understand this behavior properly
if you want to delete the li in the reverse sequence, you can refactor your `deleteQ` function like
``````function deleteQ() {
var parent = document.getElementById('list');
var children = parent.getElementsByTagName('li');
var childToRemove = children[children.length - 1];
if(childToRemove){
parent.removeChild(childToRemove);
}
}``````

@SweetCodingInc it's actually your code in the pen :smile: ... i'm trying to make it so the first element's text changes to searchText , and then after that it adds the new li's
i got it to change the text ... but it still adds the same new li too
Sweet Coding :)
@SweetCodingInc
Apr 04 2018 08:20
lol.... this is just entirely meaningless :P
``document.getElementById("element1").id = "element1"``
i think you wanted to do `==` instead
and even in that case, it's pointless
JoEezy
Apr 04 2018 08:21
oh god
Sweet Coding :)
@SweetCodingInc
Apr 04 2018 08:21

anyway..

but it still adds the same new li too

So you want, at most, only 2 li elements at any point in time?

I'm still unable to understand what you're trying to do
JoEezy
Apr 04 2018 08:23
actually i was trying to make it so instead of adding an li under element1 to the list , it changes element1's innerHTML instead, and it only starts adding li's after element1 changed

Apr 04 2018 08:33
@SweetCodingInc you there? i was able to get it to work by just copying some of your code around but i was wondering if you know of a better way to do this? I only did it this way to kind of show you what i mean: https://codepen.io/yaezah/pen/aYjXoR
Sweet Coding :)
@SweetCodingInc
Apr 04 2018 08:34
I see... So it will update the first li on first time.. and then onward it will keep adding new lis
JoEezy
Apr 04 2018 08:35
yes :smile:
Sweet Coding :)
@SweetCodingInc
Apr 04 2018 08:39
I'd do it like this
``````function list() {

if(!text) return;

var element1 = document.getElementById("element1");

var parent = document.getElementById("list");
var children = parent.getElementsByTagName('li');
var li = document.createElement("li");
var crea = li.appendChild(document.createTextNode(text));

if(element1){
element1.id = "changed";
element1.textContent = text;
} else {
parent.appendChild(li);
}
}``````
no need to do anything if textbox is empty

@JoEeeezy_twitter PRO Tip : change all `var`s to `let` and you improve on space complexity ;)
because the variables in the else part, you want them created only when control goes into else section.
with var, they will be created and hoisted, regardless of their requirement.

@habibatify_twitter You should compare strokes to par not to specific numbers.
Because of how comma works
`if (par == 4, strokes == 6)` will only really test `strokes == 6`because the value of the comma operator expression is the last value in the comma list

Hi Guys, Is there anyway to avoid manually set state loading true and false for every ajax request in React JS
``````handleSubmit = e => {
e.preventDefault();

const tagData = JSON.stringify(this.state.value.map(x => x.value));
const tagOptions = JSON.stringify(this.state.value);
const tagDataVm = {
tagData,
tagOptions
};

Post(env.tagCreate, tagDataVm)
.then(res => {
if (res.status === statusCode.Success) toastr.success("Create success");

})
.catch(() => {
});
};``````

@ngohungphuc in reactJS you must always first change the state and on the basis of state change the behaviour of your UI. I don't think there is anyway you can do it manually without changing states, otherwise it is simply like using Jquery.

I can't seem to hit 39 in the third sub array.

@zootechdrum with `if (j === 3)` you will always push the number to biggest num before it checks the last number
do the number check first then push it
@ezioda004
Apr 04 2018 15:34
@zootechdrum You can perhaps do a check in `j === 3` between `arr[i][j]` and `checkNumber` and push the bigger one in the array also in `for(var j = 0; j < arr.length;j++)` the condition should be `arr[i].length`

Please help me to look at this code. To implement the rotation diagram, there is a bug but I do not know how to change it.
let flag=true;
\$(".pagerbox li").click(function () {
let index = \$(".pagerbox li").index(".pagerbox li")
n = index;
})
function move() {
n++;
if (n === \$(".imgbox img").length) {
n = 0;
}
if (n < 0) {
n = \$(".imgbox img").length - 1;
}
}
``````    \$(".next").click(function () {
if(flag){
flag=false;
move();
}
})
\$(".prev").click(function () {
if(flag){
flag=false;
n -= 2;
move();
}
})
let t = setInterval(move, 3000);
\$("#banner").mouseleave(function () {
t=setInterval(move, 3000);
})
\$("#banner").mouseenter(function () {
clearInterval(t);
})
\$(".imgbox img").on("transitionend",function(){
flag=true;
})``````

@rajkumart08_twitter I have taken a look at your code and have found the reason
@rajkumart08_twitter there are a few issues also, there is more than one element with the id 'checkIDGrid' - you should only use an id once on your page, the same id shouldn't be given to multiple elements.
Now, the reason why your code isn't working is because the element with id checkIDGrid is dynamically added to the page, you can't attach event handlers like that to dynamically added elements.
@rajkumart08_twitter here is something you might find useful https://stackoverflow.com/questions/15090942/event-handler-not-working-on-dynamic-content
@rajkumart08_twitter you have to add the event handler to a parent element, so it can be caught when it propagates down the DOM

Hi everyone, Q- is it a good practice to always use the CSS text-transform property when I want my text on the website to be in capital letters or are their instances where i should just capitalize with capslock directly in the html document? I want my name capitalized in the main header of my website (above the nav block) - should i use CSS? Thanks!
Aga
@aga87
Apr 04 2018 19:37
im guessing the css.
Apr 04 2018 19:41
@aga87 I would use CSS if the data is dynamic, otherwise whats wrong with just capitalizing the text?
