Looping through an array of objects to display information

Looping through an array of objects to display information - javascript

I am on a Team Treehouse challenge.
My challenge is to create an array of objects which contains the students info, make a search database for it so when you search for the student, the student will appear.
The additional challenge is to print out the both students if there is 2 students of same name. I also tried adding another little challenge to list all students if user typed "list".
My code:
var message = '';
var student;
var search;
var list;
function print(message) {
var outputDiv = document.getElementById('output');
outputDiv.innerHTML = message;
}
function getStudentInfo (student) {
var report = '<h2>Student: ' + student.name + '</h2>';
report += '<p>Track: ' + student.track + '</p>';
report += '<p>Points: ' + student.points + '</p>';
report += '<p>Achievements: ' + student.achievements + '</p>';
return report;
}
while (true) {
search = prompt("Search Student records: Type a name [Martin] or [quit] to exit");
if (search === null || search.toLowerCase() === "quit") {
break;
}
for (var i = 0; i < students.length; i += 1) {
student = students [i];
if (search.toLowerCase() === student.name.toLowerCase()) {
message = getStudentInfo(student);
print(message);
break;
} else if (search.toLowerCase() === "list") {
list = '<h2>Student: ' + student.name + '</h2>';
list += '<p>Track: ' + student.track + '</p>';
list += '<p>Points: ' + student.points + '</p>';
list += '<p>Achievements: ' + student.achievements + '</p>';
print (list);
}
}
}
var students = [
{
name: 'Dave',
track: 'Front End Development',
achievements: 158,
points: 14730
},
{
name: 'Jody',
track: 'iOS Development with Swift',
achievements: '175',
points: '16375'
},
{
name: 'Jordan',
track: 'PHP Development',
achievements: '55',
points: '2025'
},
{
name: 'John',
track: 'Learn WordPress',
achievements: '40',
points: '1950'
},
{
name: 'Jordan',
track: 'Rails Development',
achievements: '5',
points: '350'
}
];

A couple of notable things:
This is poor use of a while loop and using while (true) tends to be error-prone leading to infinite loops. The point of having a prompt in a loop would be to continually expect additional input from the user, but since you break; out of every loop I don't believe that is your goal. You actually don't need a while construct at all.
You don't need so many variables to keep track of the program's state. It's fine to repeat students[i] twice rather than making a new variable for it, and you can store the user's input as toLowerCase() right away since that's all you'll ever be checking.
Unless multiple places in your code need to output to the UI, you don't need a separate function for outputting the message. You can just build up the message and output it at the end of the script. My hunch is that this build-up of the final output is your biggest point of confusion, and the extra function call adds to that.
Overall though, it looks like you were pretty close - the following code is actually shorter than what you had and mainly changes how the output message is built.
(function() {
var students = [
{
name: 'Dave',
track: 'Front End Development',
achievements: 158,
points: 14730
},

},
{
name: 'Jordan',

achievements: '5',
points: '350'
}
];
var i = 0;
var input = '';
var output = '';
function getStudentInfo (student) {
var report = '<h2>Student: ' + student.name + '</h2>';
report += '<p>Track: ' + student.track + '</p>';
report += '<p>Points: ' + student.points + '</p>';
report += '<p>Achievements: ' + student.achievements + '</p>';
return report;
}
input = prompt("Search Student records: Type a name [Martin] or [quit] to exit").toLowerCase();
if (input === 'quit' || input.length === 0) {
return; // or display some message to 'output'
}
for (i = 0; i < students.length; i++) {
if (input === 'list') {
output += getStudentInfo(students[i]);
} else if (input === students[i].name.toLowerCase()) {
output += getStudentInfo(students[i]);
}
}
document.getElementById('output').innerHTML = output;
})();

How do i stop iterating tough this array at "pgn[46]"?

How do i stop iterating tough this array at "pgn[46]"?
I want to be unable to go to the next move when i click the button. because this array will start back from 0 and if a piece is on the square it will move again. i need some more text to post this question here. I love you all, peace
$('#move1Btn').on('click', function () {
board.move(pgn[intpgnIndex])
})
var pgn = new Array()
pgn[0] = ""
pgn[1] = "e2-e4"
pgn[2] = "e7-e5"
pgn[3] = "f2-f4"
pgn[4] = "e5-f4"
pgn[5] = "f1-c4"
pgn[6] = "d8-h4"
pgn[7] = "e1-f1"
pgn[8] = "b7-b5"
pgn[9] = "c4-b5"
pgn[10] = "g8-f6"
pgn[11] = "g1-f3"
pgn[12] = "h4-h6"
pgn[13] = "d2-d3"
pgn[14] = "f6-h5"
pgn[15] = "f3-h4"
pgn[16] = "h6-g5"
pgn[17] = "h4-f5"
pgn[18] = "c7-c6"
pgn[19] = "g2-g4"
pgn[20] = "h5-f6"
pgn[21] = "h1-g1"
pgn[22] = "c6-b5"
pgn[23] = "h2-h4"
pgn[24] = "g5-g6"
pgn[25] = "h4-h5"
pgn[26] = "g6-g5"
pgn[27] = "d1-f3"
pgn[28] = "f6-g8"
pgn[29] = "c1-f4"
pgn[30] = "g5-f6"
pgn[31] = "b1-c3"

pgn[49] = ""
var intpgnIndex = 0;
function writeThing() {
if ( intpgnIndex == pgn.length ) intpgnIndex = 0;
intpgnIndex++;
}

I would check the value at the index and see if it is an empty string:
$('#move1Btn').on('click', function () {
var move = pgn[intpgnIndex];
if (move) {
board.move(move);
}
})

how can we display different legends container for same graph(sunburst drill down)? in Amcharts4

I was trying to add two legends containers for the same graph(sunburst drill-down). one on the left side and another on the right side of the graph.
After lots of research, I found the solution but it was for piechart not for sunburst drill down. I want the same solution for sunburst drill down.
Below is the Image of the solution which I found.

how to dynamically resize text in a vue component

I have built an application with different widgets you can drop into a dashboard. Each widget contains a component that a user would like to see (kind of like grafana if you've ever seen it).
Question: When the user drags the grid-item to increase or decrease the size, how do you update the html inside of my component to adjust to the size of the new item?
What I've tried:
attempted to wrap the p tags in an SVG and use viewport.
attempted to change my size to VW to dynamically scale by the viewport but the viewport is not of the component but of the entire spa.
I attempted to get the parent size using this.$parent and did some math to get the text size and dynamically assign it to a component but this was very messy. Also, the sizes displayed were not right.
Below is my code for my grid using the vue-grid-layout package
<grid-layout
ref="widgetGrid"
:layout.sync="widgets"
:col-num="12"
:row-height="verticalSize"
:is-draggable="editable"
:is-resizable="editable"
:is-mirrored="false"
:responsive="true"
:autoSize="editable"
:prevent-collision="false"
:vertical-compact="false"
:margin="[10, 10]"
:use-css-transforms="true"
#layout-updated="layoutUpdatedEvent"
>
<grid-item
:ref="`widget_${widget.i}`"
v-for="widget in widgets"
:key="widget.i"
:x="widget.x"
:y="widget.y"
:w="widget.w"
:h="widget.h"
:i="widget.i"
:static="!editable"
>
<template>
<component
:is="widget.WidgetType"
:setup="false"
:widgetConfig="widget.WidgetConfig"
></component>
</template>
</grid-item>
</grid-layout>
My component that I'm trying to resize the text for is below. It's a vue file and I've included styling.

If you'd like to resize the text size for your clock component, one solution is uses svg -> viewbox the one you already mentioned. But you need to use <text> instead of <p>.
Below is the demo:
Vue.component('v-clock',{
template:`
<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">
<text x="0" y="25" fill="red">{{date}}</text>
<text x="0" y="75" fill="red">{{time}}</text>
</svg>
`,
data() {
return {
time: '',
date: '',
week: ['SUN', 'MON', 'TUE', 'WED', 'THU', 'FRI', 'SAT'],
ticker: null
};
},
created() {
this.ticker = setInterval(this.updateTime, 1000);
},
mounted() {
this.showDate =
this.widgetConfig?.Settings?.find((x) => x.Key === 'ShowDate').Value ||
false;
this.showTime =
this.widgetConfig?.Settings?.find((x) => x.Key === 'ShowTime').Value ||
false;
},
methods: {
updateTime() {
let cd = new Date();
this.time =
this.zeroPadding(cd.getHours(), 2) +
':' +
this.zeroPadding(cd.getMinutes(), 2) +
':' +
this.zeroPadding(cd.getSeconds(), 2);
this.date =
this.zeroPadding(cd.getFullYear(), 4) +
'-' +
this.zeroPadding(cd.getMonth() + 1, 2) +
'-' +
this.zeroPadding(cd.getDate(), 2) +
' ' +
this.week[cd.getDay()];
},
zeroPadding(num, digit) {
let zero = '';
for (let i = 0; i < digit; i++) {
zero += '0';
}
return (zero + num).slice(-digit);
}
}
})
new Vue ({
el:'#app',
data () {
return {
size: 100
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.16/vue.js"></script>

Loop through array data in carousel not working

I'm trying to build a carousel in JS that uses an array to store my data.
I want my box on the left to show the value for "Client" and the box on the right to show the value for "Candidate".
I can't seem to get it working despite what I believe is all correct?
let testimonials = [{
client: "Raphel",
candidate: "male"
},
{
client: "Tom",
candidate: "male"
},
{
client: "Jerry",
candidate: "male"
},
{
client: "Dorry",
candidate: "female"
}
];
var i = 0;
function nextItem() {
i = i + 1;
i = i % testimonials.length;
return testimonials[i].candidate;
}
function prevItem() {
if (i === 0) {
i = testimonials.length;
}
i = i - 1;
return testimonials[i].client;
}
window.addEventListener('load', function() {
$('.client-box').html(testimonials[i].client);
$('.candidate-box').html(testimonials[i].candidate);
$('.left-btn').on('click', function(e) {
$('.client-box').html(prevItem());
$('.candidate-box').html(prevItem());
});
$('.right-btn').on('click', function(e) {
$('.client-box').html(nextItem());
$('.candidate-box').html(nextItem());
});
});
https://jsfiddle.net/cL5mok3f/

Fixing the code:
let testimonials = [{
client: "Raphel",
candidate: "male"
},
{
client: "Tom",
candidate: "male"
},
{
client: "Jerry",
candidate: "male"
},
{
client: "Dorry",
candidate: "female"
}
];
var i = 0;
function nextItem() {
i = i + 1;
i = i % testimonials.length;
return testimonials[i];
}
function prevItem() {
if (i === 0) {
i = testimonials.length;
}
i = i - 1;
return testimonials[i];
}
window.addEventListener('load', function() {
$('.client-box').html(testimonials[i].client);
$('.candidate-box').html(testimonials[i].candidate);
$('.left-btn').on('click', function(e) {
var prev = prevItem();
$('.client-box').html(prev.client);
$('.candidate-box').html(prev.candidate);
});
$('.right-btn').on('click', function(e) {
var next = nextItem();
$('.client-box').html(next.client);
$('.candidate-box').html(next.candidate);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="client-box"></div>
<div class="candidate-box"></div>
<input type="button" class="left-btn" value="Prev" />
<input type="button" class="right-btn" value="Next" />

To achieve expected result, use below option
Issue: PrevItem and nextItem methods are called twice on clicking left and right which creates inconsistent carousel
Code sample
let testimonials = [
{client: "Raphel", candidate: "male"},
{client: "Tom", candidate: "male"},
{client: "Jerry", candidate: "male"},
{client: "Dorry", candidate: "female"}
];
var i = 0;
$('.client-box').text(testimonials[0].client);
$('.candidate-box').text(testimonials[1].candidate);
function nextItem() {
i = i + 1;
if (i === testimonials.length) {
i = i % testimonials.length;
}
return testimonials[i];
}
function prevItem() {
if (i === 0) {
i = testimonials.length;
}
i = i - 1;
console.log("prev", i)
return testimonials[i];
}

Javascript - Fixing searching system?

Down below, there's two pieces of codes. For infinite scroll & search system. Everything works, but the problem with the search system is that, if I search something, then it messes up positioning of the cards or boxes. They should be on one line, if you search them, but those a bit up etc.. I also have added an picture about that. 2nd problem is that, I have an Infinite scroll on my site, but I think I would have to change the search system to search from JSON Data, so it would work correctly? By that I mean, You type something into search, click enter then it searches matches from the JSON and then shows them in that container. I hope I was clear enough about my problem and I hope someone can help me out to solve it :). Thanks to everyone! :)

Overview
First off, I have no visibility to the
...messes up positioning of the cards or boxes...
since I do not know what your CSS consists of so I simply made some guesses on that. I suspect it may be due to the actual rendering of your items somehow. To assist in this I removed all the CSS from the injected markup as injecting those "style" attributes is not best practice and frankly difficult to debug as you seem to have experienced. I made an attempt but you will need to adjust the CSS I have provided as it simply does not have all yours in it.
To assist with this, I simply did a "replace" with the current page rather than append each time and then face the challenge of end of scroll/start and deal with the search disruption of that.
I removed the injection of duplicate id on the button and instead used a class injection instead. This will resolve the issue of the invalid HTML which would cause unexpected results at some point that would be very difficult to debug.
The more difficult issue is the dynamic nature of your items array when searching the on-page object list. This I have addressed by creation of a "view candidate list called currentSearch which I have taken the liberty of adding to a name called myApp.data as myApp.data.currentSearch.
Speaking of the namespace, I did that to avoid multiple global objects. I also did that with my custom functions as a best practice.
Here is my sample markup that I used:
<div id="search">
<input id="SearchItemsFromList" type="text" />
</div>
<ul id="inventory">
</ul>
CSS
Here is the CSS which in great part was extracted from the style properties. I took the liberty of naming them poorly as first-style-thing class, second-style-thing etc. which simply coordinate to the injected sequence of elements. This has the additional benefit of reducing the injection string size as well.

Code:
About the code, note the items object which I simply made from reverse engineering your injection code and likely needs adjusted to your exact object properties.
Note the debounce function which addresses an issue where you might fire the scroll/mouse wheel events too often. I added a "throttle" which you might use instead, borrowed from here: https://remysharp.com/2010/07/21/throttling-function-calls Speaking of, I added the "wheel" event to the "scroll" event so that if you are at the top/bottom of the scroll the mouse wheel can also fire the scroll when no scroll actually occurs. I did not address other possible challenges such as the down/up arrow when the scroll is at the top/bottom; I will leave that up to you to address based upon your needs.
Note that upon a "search" event when typing, I reset the currentSearch list.
I left some console.log in place which you can remove - but allows you to see the page and some event fire logging.
Here is a sample so you can try this all out https://jsfiddle.net/MarkSchultheiss/hgfhh2y7/3/

Final note on the code, you have a quite long, difficult to maintain conditional which I replaced by added an array with the exclusions and then the code uses it with a filter: .filter(function(itemValue) {
return !!(myApp.data.excludes.indexOf(itemValue) == -1)
})
