Javascript - a problem with a two-step text input word conversion

Here I am making a word conversion tool which changes a certain word X into Y, or X to Y to Z by using javascript.
Progress: HERE
Here is the entire javascript:
var conversion = {
"one":"two",
};
var conversion2 = {
"two":"three",
};
var maxLength = Object.keys(conversion)
.reduce((a, b) => a.length > b.length ? a : b)
.length;
function convert (text) {
var converted = "";
var cur = 0;
while (cur < text.length) {
var testedPhoneme;
var symbol = undefined;
for (var length = maxLength; length > 0; length --) {
testedPhoneme = text.substr(cur, length);
if (conversion[testedPhoneme]) {
symbol = conversion[testedPhoneme];
break; // stop the loop
}
}
if (symbol) {
converted += symbol;
cur += testedPhoneme.length;
}
else {
converted += text[cur]
cur++;
}
}
return converted
}
var maxLength2 = Object.keys(conversion2)
.reduce((a, b) => a.length > b.length ? a : b)
.length;
function convert2 (text) {
var converted2 = "";
var cur2 = 0;
while (cur2 < text.length) {
var testedPhoneme2;
var symbol2 = undefined;
for (var length = maxLength2; length > 0; length --) {
testedPhoneme2 = text.substr(cur2, length);
if (conversion2[testedPhoneme2]) {
symbol2 = conversion2[testedPhoneme2];
break; // stop the loop
}
}
if (symbol2) {
converted2 += symbol2;
cur2 += testedPhoneme2.length;
}
else {
converted2 += text[cur2]
cur2++;
}
}
return converted2
}
function onInputTextChange(txt) {
var outputTextareaElem = document.getElementById("output_textarea");
var div = document.createElement("div");
var outputHtmlEntities = convert(txt);
div.innerHTML = outputHtmlEntities;
outputTextareaElem.value = div.innerText;
}
function onOutputTextChange(txt) {
var outputTextareaElem2 = document.getElementById("output_textarea2");
var div = document.createElement("div");
var outputHtmlEntities2 = convert2(txt);
div.innerHTML = outputHtmlEntities2;
outputTextareaElem2.value = div.innerText;
}
In the page that I made so far, there are three <textarea>s; Input, Output and Output2.
Currently, thanks to this piece of code;
var conversion = {
"one":"two",
};
var conversion2 = {
"two":"three",
};
If one is typed into Input, Output renders two. If two is manually typed into Output, three gets rendered in Output2.
Here is the problem, I want to render three in Output2 only through typing one into Input, but a direct two-step conversion seems unavailable yet. In other words, Input > Output (one > two) and Output > Output2 (two > three) conversion is available, but Input > Output > Output2 (one > two > three) is unavailable.
What needs to be done to solve this? Any help would be appreciated.

Ok, not exactly what you asked, but I could do something that works
Here is the example : https://jsfiddle.net/alias_gui3/8knw57u0/94/
how to use it :
to add new characters OR new languages/scripts
just complete the dictionnary :
var dictionnary = [
{
latin: "u",
japanese: "う",
emoji: "👋"
// add any script for every characters
},{
latin: "ku",
japanese: "く",
emoji: "👀"
},{
latin: "tsu",
japanese: "つ",
emoji: "🤖"
}
// add any character with the same format
]
to add new textareas :
give your textarea a recognizable id (eg. id="cyrillic")
then connect your textarea with this method:
// connect your textareas below !!
addTextArea(
document.querySelector("#latin"),
"latin"
);
addTextArea(
document.querySelector("#japanese"),
"japanese"
);
addTextArea(
document.querySelector("#emoji"),
"emoji"
);
// add new textarea with a new language here
then all the connections are done, you can edit all your textareas, if they recognise a character they will translate it in all the other textareas
full code
var dictionnary = [
{
latin: "u",
japanese: "う",
emoji: "👋"
// add any script for every characters
},{
latin: "ku",
japanese: "く",
emoji: "👀"
},{
latin: "tsu",
japanese: "つ",
emoji: "🤖"
}
// add any character with the same format
]
// calculate the max length for each language :
var max = {}
dictionnary.forEach(
char => {
Object.keys(char).forEach(script => {
max[script] = max[script]
? char[script].length > max[script]
? char[script].length
: max[script]
: char[script].length
})
}
)// now max contains the maximum length of sequence
// for each language
function findSymbol (
originSymbol,
originScript,
destinationScript
) {
for (var i = 0; i < dictionnary.length; i++) {
var char = dictionnary[i];
if (char[originScript] === originSymbol) {
return char[destinationScript]
}
}
return false // if not found
}
function translate (
text,
originScript,
destinationScript
) {
var cur = 0;
var translated = "";
var maxLength = max[originScript]
while (cur < text.length) {
var testedPhoneme;
var symbol = false;
for (var length=maxLength; length > 0; length--) {
testedPhoneme = text.substr(cur, length);
symbol = findSymbol(
testedPhoneme,
originScript,
destinationScript
)
if (symbol) {
break; // stop the loop
}
}
if (symbol) {
translated += symbol;
cur += testedPhoneme.length;
}
else {
translated += text[cur];
cur++;
}
}
return translated
}
var textareas = []; // the list of your textareas
function addTextArea(element, originScript) {
textareas.push({
element: element,
script: originScript
})
element.addEventListener("input", function (e) {
signalTextChanged(element, originScript)
});
}
function signalTextChanged (
originElement,
originScript
) {
var originText = originElement.value;
textareas.forEach(function (textarea) {
if (textarea.element !== originElement) {
var translated = translate(
originText,
originScript,
textarea.script
)
textarea.element.value = translated;
}
})
}
// connect your textareas below !!
addTextArea(
document.querySelector("#latin"),
"latin"
);
addTextArea(
document.querySelector("#japanese"),
"japanese"
);
addTextArea(
document.querySelector("#emoji"),
"emoji"
);

I'm not sure if I fully understand what you're trying to achieve here
There are some duplications in your code, what if you'll have 10 fields for output, will you create a special function for each of them?
Try to simplify things.
One way would be to loop through all of your lists as follows:
Put all your conversation in a list
var lists = [conversion, conversion2];
Add isInNextList function to check if your text is a key in the next list
function isInNextList(index, key) {
if (lists.length < index) {
return false;
}
return Object.keys(lists[index]).includes(key);
}
change your onInputTextChange function as follow:
function onInputTextChange(txt) {
var index = 0;
var text = txt;
while (isInNextList(index, text)) {
var outputTextareaElem = document.getElementById(
'output_textarea_' + index
);
var div = document.createElement('div');
text = lists[index][text]; //next key
index++;
div.innerHTML = text;
outputTextareaElem.value = div.innerText;
}
}
change your output textarea's ids to contain the index
id="output_textarea_0"
id="output_textarea_1"
There are other improvements that can be made like:
Creating the output fields dynamically,
Clear output fields etc.

Onclick event in JS shows results for a second before automatically resetting form

This is a simple quiz/questionnaire, that'll display results of the quiz on submission. It shows the results, but only for about half a second before resetting the page. I would also like for the page to show an alert if the user says they're under 18 when the quiz is submitted; it wouldn't keep them from seeing the answers, but just giving them a message.
function checkAge() {
if(age<18) {
alert("Always make sure you have adult supervision while caring for and handling any venomous arachnid.");
} }
function generateAnswers() {
var choice1score = 0;
var choice2score = 0;
var choice3score = 0;
var choice4score = 0;
}
var chosenAnswers = document.getElementsByTagName('result');
for (i=0; i<chosenAnswers.length; i++) {
if (chosenAnswers[i].checked) {
// add 1 to that choice's score
if (chosenAnswers[i].value == 'choice1') {
choice1score = choice1score + 1;
}
if (chosenAnswers[i].value == 'choice2') {
choice2score = choice2score + 1;
}
if (chosenAnswers[i].value == 'choice3') {
choice3score = choice3score + 1;
}
if (chosenAnswers[i].value == 'choice4') {
choice4score = choice4score + 1;
}
}
}
var maxscore = Math.max(choice1score,choice2score,choice3score,choice4score);
var resultBox = document.getElementById('result');
if (choice1score == maxscore) {
resultBox.innerHTML = "Asian Forest Scorpion"
}
if (choice2score == maxscore) {
resultBox.innerHTML = "Deathstalker Scorpion"
}
if (choice3score == maxscore) {
resultBox.innerHTML = "Desert Hairy Scorpion"
}
if (choice4score == maxscore) {
resultBox.innerHTML = "Emperor Scorpion"
}
}
This is where I put the code:
https://codepen.io/cryceks/pen/vjgzOZ

Use:
event.preventDefault();
This prevents the webpage from reloading and therefore clearing form data

Js & Jquery:Understanding a search code with JSON request

i have a js search in my page that i don't get perfectly how does work because i don't know 100% js and jquery. As far as i think the code takes the input and search match with a link to a database that returns a JSON value depending on what name you put on the link (?name="the-input-name-here"), then, the code parse the json and determinates if the name of the input it's a valid surname and if it is the check if it has a running page, if it has redirects you to that page. If the input is a valid surname but doesn't have a running page it redirects you to "landing-page-yes.html". If the input isn't a valid surname it redirects you to "landing-page-no.html".
I need help to understand how the code does this in order to make a simplify version. How that call to another url database is parsed by the js ? How can i think something similar with a backend and ajax ? I need to understand 100% what this code does and i'm kinda lost.
THANKS !

Illustrator JavaScript only works once - won't toggle

I'm writing a script which changes the colours of a stick-man's arms and legs. Once "he" is selected, it effectively just mirrors the colours:
//Declare and initialize variables
var msgType = "";
var app;
var docRef = app.activeDocument;
var testColor = docRef.swatches.getByName("CMYK Green");
var leftColor = docRef.swatches.getByName("LeftColor");
var rightColor = docRef.swatches.getByName("RightColor");
function sameColor(CMYKColor1, CMYKColor2) {
"use strict";
var isTheSameColor;
if ((CMYKColor1.cyan === CMYKColor2.cyan) && (CMYKColor1.magenta === CMYKColor2.magenta) && (CMYKColor1.yellow === CMYKColor2.yellow) && (CMYKColor1.black === CMYKColor2.black)) {
isTheSameColor = true;
} else {
isTheSameColor = false;
}
return isTheSameColor;
}
// check if a document is open in Illustrator.
if (app.documents.length > 0) {
var mySelection = app.activeDocument.selection;
var index;
// Loop through all selected objects
for (index = 0; index < mySelection.length; index += 1) {
// Switch left and right colours
if (sameColor(mySelection[index].strokeColor, leftColor.color)) {
mySelection[index].strokeColor = rightColor.color;
}
if (sameColor(mySelection[index].strokeColor, rightColor.color)) {
mySelection[index].strokeColor = leftColor.color;
}
if (sameColor(mySelection[index].fillColor, leftColor.color)) {
mySelection[index].fillColor = rightColor.color;
}
if (sameColor(mySelection[index].fillColor, rightColor.color)) {
mySelection[index].fillColor = leftColor.color;
}
}
}
It works, but it only works once (i.e. I can't toggle the change again). If I undo the change and try again it works again. Why is this?

After a lot of head-scratching / debugging it turns out that it was changing the CMYK values to be not quite the same (by a tiny fraction).
Changed the following:
if ((CMYKColor1.cyan === CMYKColor2.cyan) ...
to:
if ((Math.round(CMYKColor1.cyan) === Math.round(CMYKColor2.cyan)) ...
and it works fine now.

javascript countdown with showing milliseconds

I want to do a count down and want to show like format as Minutes:Seconds:Milliseconds. I made a count down with jquery plug-in countdown but it shows just Minutes:Seconds format.
Is there any way to make it right?
Many Thanks!

Hi guys I have developed a code for my self use the following code
counter for 20 seconds
var _STOP =0;
var value=1999;
function settimer()
{
var svalue = value.toString();
if(svalue.length == 3)
svalue = '0'+svalue;
else if(svalue.length == 2)
svalue = '00'+svalue;
else if(svalue.length == 1)
svalue = '000'+svalue;
else if(value == 0)
svalue = '0000';
document.getElementById('cn1').innerHTML = svalue[0];
document.getElementById('cn2').innerHTML = svalue[1];
document.getElementById('cn3').innerHTML = svalue[2];
document.getElementById('cn4').innerHTML = svalue[3];
value--;
if (_STOP==0 && value>=0) setTimeout("settimer();", 10);
}
setTimeout("settimer()", 10);

Try this: http://jsfiddle.net/aamir/TaHtz/76/
HTML:
<div id="timer"></div>
​
JS:
var el = document.getElementById('timer');
var milliSecondsTime = 10000;
var timer;
el.innerHTML = milliSecondsTime/1000;
timer = setInterval(function(){
milliSecondsTime = milliSecondsTime - 1000;
if(milliSecondsTime/1000 == 0) {
clearTimeout(timer);
el.innerHTML = 'BOOOOM';
}
else {
el.innerHTML = milliSecondsTime/1000;
}
},1000);
​

If you want to make your own timer.
read this earlier question
How to create a JQuery Clock / Timer

Try setting the format parameter - http://keith-wood.name/countdownRef.html#format
On further reading, this plugin doesn't do milliseconds. At this point, you either have to edit the actual plugin code or find a new plugin.

I completely agree with #Matt Ball's comment.It may also cause the browser to crash.
Why don't you try this solution instead
jQuery 1 minute countdown with milliseconds and callback

I did it like this (generic counter from N to X (X > N)):
var dynamicCounterAddNewValue = 20;
var currentDynamicUpdater;
function dynamicCounterForValueForControlUpdater(_updaterData) {
_updaterData.from += dynamicCounterAddNewValue;
if (_updaterData.from > _updaterData.to) {
_updaterData.from = _updaterData.to;
}
_updaterData.c.html(_updaterData.from.toString());
if (_updaterData.from < _updaterData.to) {
currentDynamicUpdater = setTimeout(
dynamicCounterForValueForControlUpdater,
10,
{
c: _updaterData.c,
from: _updaterData.from,
to: _updaterData.to
}
);
}
else {
clearTimeout(currentDynamicUpdater);
}
return;
}
// _c -> jQuery object (div,span)
// _from -> starting number
// _to -> ending number
function dynamicCounterForValueForControl(_c, _from, _to) {
clearTimeout(currentDynamicUpdater);
dynamicCounterForValueForControlUpdater(
{
c: _c,
from: _from,
to: _to
}
);
return;
}
EDIT: Updated version (more flexible - for N elements one after another):
(input element is Array of elements for making them dynamic-counts)
var dynamicCounterTimeout = 10;
var currentDynamicUpdater;
function odcArray(_odca) {
this.odca = _odca;
return;
}
function odc(_c, _from, _to) {
this.c = _c; // $('#control_id')
this.from = _from; // e.g. N
this.to = _to; // e.g. M => (M >= N)
var di = parseInt(_to / 45, 10);
if (di < 1) {
di = 1;
}
this.dynamicInc = di;
return;
}
function dynamicCounterForValueForControlUpdater(_odca) {
if (
_odca.odca === null
||
!_odca.odca.length
) {
clearTimeout(currentDynamicUpdater);
return;
}
var o = _odca.odca[0];
o.from += o.dynamicInc;
if (o.from > o.to) {
o.from = o.to;
_odca.odca.shift(); // Remove first element
}
o.c.html(o.from.toString());
currentDynamicUpdater = setTimeout(
dynamicCounterForValueForControlUpdater,
dynamicCounterTimeout,
_odca
);
return;
}
function dynamicCounterForValueForControl(_odca) {
clearTimeout(currentDynamicUpdater);
// SETUP all counters to default
for (var i = 0; i < _odca.odca.length; i++) {
_odca.odca[i].c.html(_odca.odca[i].from.toString());
}
dynamicCounterForValueForControlUpdater(
_odca
);
return;
}
