How to modify javascript to have html result instead of show out the html code in a comment system?

Currently,
when i input test,
the comment system directly show my typing, "test"
Modify to,
I would like the modify the javascript code that when i input test,
it convert to html result "test" (a hyperlink to "#").
How can i modify following code? Many thanks!
function fetchComments(leaveRequestId) {
$('#existingComments').html(lang_Loading);
params = 'leaveRequestId=' + leaveRequestId;
$.ajax({
type: 'GET',
url: getCommentsUrl,
data: params,
dataType: 'json',
success: function(data) {
var count = data.length;
var html = '';
var rows = 0;
$('#existingComments').html('');
if (count > 0) {
html = "<table class='table'><tr><th>" + lang_Date + "</th><th>" + lang_Time + "</th><th>" + lang_Author + "</th><th>" + lang_Comment + "</th></tr>";
for (var i = 0; i < count; i++) {
var css = "odd";
rows++;
if (rows % 2) {
css = "even";
}
var comment = $('<div/>').text(data[i]['comments']).html();
html = html + '<tr class="' + css + '"><td>' + data[i]['date'] + '</td><td>' + data[i]['time'] + '</td><td>' +
data[i]['author'] + '</td><td>' + comment + '</td></tr>';
}
html = html + '</table>';
} else {
}
$('#existingComments').append(html);
}
});
}
<div id="existingComments">
<span><?php echo __('Loading') . '...';?></span>
</div>

var comment = $('<div/>').text(data[i]['comments']).html();
You're explicitly escaping the data from the Ajax request so that it shows up as text and isn't treated as HTML source code.
If you don't want to do that, then just don't do it!
(Do be careful not to expose yourself to stored XSS attacks though)

$('#existingComments').html(html);

How to get rid of many IFs and make a system to differ elements?

In this piece of code you can see a JSON request that fetches some data. I need some help to check certain opportunities of minimizing the code and getting iterations with FOR instead of many IFs. Also, it would be nice if you advise anything on the differentiation system (how to make elements differ from each other)
<script type="text/javascript">
function deleteRow0() {
$('p.row0').remove();
};
function deleteRow1() {
$('p.row1').remove();
};
function deleteRow2() {
$('p.row2').remove();
};
function deleteRow3() {
$('p.row3').remove();
};
function deleteRow4() {
$('p.row4').remove();
};
</script>
<script type="text/javascript">
function hello2() {
//GETTING JSON INFO
$.getJSON("https://rawgit.com/Varinetz/e6cbadec972e76a340c41a65fcc2a6b3/raw/90191826a3bac2ff0761040ed1d95c59f14eaf26/frontend_test_table.json", function(json) {
$('#table-cars').css("display", "grid");
for (let counter = 0; counter < json.length; counter++) {
$('#table-cars').append("<p class='row" + counter +" main-text'>" + json[counter].title + "<br/>" + "<span class='sub-text'>" + json[counter].description + "</span>" + "</p>"
+ "<p class='row" + counter +" main-text'>" + json[counter].year + "</p>"
+ "<p id='color" + [counter] + "' class='row" + counter +" main-text'>" + json[counter].color + "</p>"
+ "<p id='status" + [counter] + "' class='row" + counter +" main-text'>" + json[counter].status + "</p>"
+ "<p class='row" + counter +" main-text'>" + json[counter].price + " руб." + "</p>"
+ "<p class='row" + counter +" main-text'>" + "<button class='delete' onclick='deleteRow" + [counter] + "()'>Удалить</button>" + "</p>");
// COLOR TEXT REPLACEMENT
if ($('p#color0').text("red")){
$('p#color0').text("").append("<img src='red.png'>");
}
if ($('p#color1').text("white")) {
$('p#color1').text("").append("<img src='white.png'>");
}
if ($('p#color2').text("black")) {
$('p#color2').text("").append("<img src='black.png'>");
}
if ($('p#color3').text("green")) {
$('p#color3').text("").append("<img src='green.png'>");
}
if ($('p#color4').text("grey")) {
$('p#color4').text("").append("<img src='grey.png'>");
}
// STATUS TEXT REPLACEMENT
if ($('p#status0').text("pednding")) {
$('p#status0').text("").append("Ожидается");
}
if ($('p#status1').text("out_of_stock")) {
$('p#status1').text("").append("Нет в наличии");
}
if ($('p#status2').text("in_stock")) {
$('p#status2').text("").append("В наличии");
}
if ($('p#status3').text("out_of_stock")) {
$('p#status3').text("").append("Нет в наличии");
}
if ($('p#status4').text("in_stock")) {
$('p#status4').text("").append("В наличии");
}
}
});
}
</script>
I expect this to be something like:
1) Iteration: For each p.row(i) {
compare it to many color (json.color)};
2) Any suggestion on differentiation system (i.e. changes in the FOR section, so it gives something easier to work with, not just simple p.row(n)). Of course, if it is possible.

I'm not going to rewrite the entire script, but in principle it would be something like this:
for (i = 0; i < 5; i++) {
var colors = ["red", "white", "black", "green", "grey"];
if ($('p#color' + i).text() == colors[i]){
$('p#color' + i).text("").append("<img src='" + colors[i] + ".png'>");
}
}
#Evik Ghazarian has a quality solution for the Text Translation portion of your script. Since this is the accepted answer, he allowed me to copy his solution so that the answers would be together:
function getTranslate(input) {
var inputMap = {
"pednding": "Ожидается",
"out_of_stock": "Нет в наличии",
"in_stock": "В наличии"
}
var defaultCode = input;
return inputMap[input] || defaultCode;
}
for (let i = 0; i < 5 , i ++){
var text = $("p#status"+i).text();
$("p#status"+i).text("").append(getTranslate(text));
}
Dynamic Iteration Counters
#Barmar mentioned in the comments below that the for loops that set a max iteration via i < 5 should actually be rewritten dynamically. I'll leave it to the OP to decide the best way to do this, but a good example might be something like i < json.length as used in the OP's original for loop.

First of all your code won't work because you are setting the text rather than comparing it. Second, you don't need to compare: just set the img src to text. Like below:
REMEMBER THIS IS FOR COLOR TEXT REPLACEMENT PART OF YOUR QUESTION
for (let i = 0; i < 5 , i ++){
let color = $("p#color"+i).text() + ".png";
$("p#color"+i).text("").append("<img src=" + color + ">");
}
FOR TEXT TRANSLATION YOU CAN USE:
function getTranslate(input) {
var inputMap = {
"pednding": "Ожидается",
"out_of_stock": "Нет в наличии",
"in_stock": "В наличии"
}
var defaultCode = input;
return inputMap[input] || defaultCode;
}
for (let i = 0; i < 5 , i ++){
var text = $("p#status"+i).text();
$("p#status"+i).text("").append(getTranslate(text));
}

Add new line using jQuery concat

Through ajax response I'm passing array data from controller to blade.
On Ajax success I'm looping through array with 2 elements and concatenating string to display later on in my bootstrap popover.
success: function (data) {
var content = "";
var num = 1;
for (var i = 0; i < data.length; i++) {
content = content.concat(num + "." + " " + data[i]);
num++;
}
$("#content").popover({content: content});
}
Result:
I would like to add new line, so that each item or "artikel" would be displayed in new line e.g. :
1.Artikel...
2.Artikel...
I tried to add "\n" (as below) or html break but nothing works, it only appends as string.
content = content.concat(num + "." + " " + data[i] + "\n");

Use this:
content.concat(num + "." + " " + data[i] + "<br/>");
And this:
$("#content").popover({ html:true, content: content });

Insert "and" before the last element jquery

var swTitle = {};
var favorite = [];
$.each($("input[name='Title']:checked"), function() {
favorite.push($(this).val());
console.log($("input[name='Title']:checked"));
});
swTitle.domain = favorite;
var List = {};
for (var m = 0; m < favorite.length; m++) {
var swTitleObj = [];
$.each($('input[name="' + swTitle.domain[m] + '"]:checked'), function() {
console.log(swTitle.domain[m]);
swTitleObj.push($(this).attr("class"));
console.log(swTitleObj);
});
List[swTitle.domain[m]] = swTitleObj;
}
var swSkillData = " ";
$.each(List, function(key, value) {
console.log(key + ":" + value);
swSkillData += '<li>' + key + '&nbsp' + ':' + '&#160' + value + '</li>';
});
Output will be like:
Fruits:Apple,Banana,Orange,Grapes
I want my output be like:
Fruits:Apple,Banana,Orange & Grapes
I have an array of keys and values separated by commas. I want to insert "and" and remove the comma before the last checked element. Kindly help me out with this issue.

I think you can reduce your code, with an option of adding and before the last element like,
var inputs=$("input[name='Title']:checked"),
len=inputs.length,
swSkillData='',
counter=0;// to get the last one
$.each(inputs, function() {
sep=' , '; // add comma as separator
if(counter++==len-1){ // if last element then add and
sep =' and ';
}
swSkillData += '<li>' + this.value + // get value
'&nbsp' + ':' + '&#160' +
this.className + // get classname
sep + // adding separator here
'</li>';
});
Updated, with and example of changing , to &
$.each(List, function(key, value) {
console.log(key + ":" + value);
var pos = value.lastIndexOf(',');// get last comma index
value = value.substring(0,pos)+' & '+value.substring(pos+1);
swSkillData += '<li>' + key + '&nbsp' + ':' + '&#160' + value + '</li>';
});
Snippet
var value ='Apple,Banana,Orange,Grapes';var pos = value.lastIndexOf(',');// get last comma index
value = value.substring(0,pos)+' & '+value.substring(pos+1);
console.log(value);

Here is an easy and customizable form of doing it.
(SOLUTION IS GENERIC)
$(document).ready(function() {
var ara = ['Apple','Banana','Orange','Grapes'];
displayAra(ara);
function displayAra(x) {
var str = '';
for (var i = 0; i < x.length; i++) {
if (i + 1 == x.length) {
str = str.split('');
str.pop();
str = str.join('');
str += ' and ' + x[i];
console.log(str);
$('.displayAra').text(str);
break;
}
str += x[i] + ',';
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Fruits : <span class="displayAra"></span>

str = str.replace(/,(?=[^,]*$)/, 'and')
I solved my own issue. I replaced my last comma with "and" using the above regex. Thanks to Regex!!!

adding a class to an element depending on a Json feed

Hit a slight bump on something.
So I have a spreadsheet feed coming through via json.
Once they are loaded, if they contain a certain word, I want an elment that is already on the page to do something.
Having some trouble.
Here is my code:
/*feed*/
function displayContent(json) {
var len = json.feed.entry.length
var divtag = ''
for (var i=0; i<len; i++) {
divtag += [
'<div id=' +' tooltipwrap' + i + '>' +
'<span style="font-size:22px; font-weight:600;">',
json.feed.entry[i].gsx$studentname.$t + ' ' +
'<span class="hide" style="font-size:18px; font-weight:300;">',
json.feed.entry[i].gsx$classlevel.$t
+ '</span>' + '<span id=' + 'tooltipside' + i +'>' +
json.feed.entry[i].gsx$gender.$t + '-' +
'</span>',
'</div>'
].join('');
}
document.getElementById('tipswrap').innerHTML = divtag
}
/* what I wanted to do */
if ($('#tooltipside0').html() === "Senior") {
$("#test1").addClass('no');
}
Here is the JSFiddle

Pay attention to the tabulation. Right now your code is hard to read because you have failed to do so.
Here:
var len = json.feed.entry.length
var divtag = ''
you are missing semi-colons. You have to put semi-colon at the end of any operation, like this:
var len = json.feed.entry.length;
var divtag = '';
Semi-colons serve as operation separators.
Here:
divtag += [
'' +
'',
json.feed.entry[i].gsx$studentname.$t + ' ' +
'',
json.feed.entry[i].gsx$classlevel.$t
+ '' + '' +
json.feed.entry[i].gsx$gender.$t + '-' +
'',
'</div>'
].join('');
You have multiple problems:
You have failed to put your html attributes into quotes, so the resulting html will be invalid. Also, you have used comma instead of plus at the last concatenation.
CONCLUSION: You are obviously not ready to implement this code, because:
- You lack Javascript syntax knowledge
- You lack HTML syntax knowledge
- You do not pay attention to tabulation
As a consequence, your main problem is not what the question states, namely, how to add a class to an element depending on JSON feed. Your main problem is that you lack Javascript and HTML education. Please, follow some tutorials to be able to solve a problem and after that try again to solve your problem. If you fail to do so, then you will have at least an educated guess.

After adding the content to tipswrap add the condition
document.getElementById('tipswrap').innerHTML = divtag; //$('#tipswrap').html(divtag)
if ($.trim($('#tooltipside0').html()) === "Senior") {
$("#test1").addClass('no');
}
Demo: Fiddle

I recommend you add a class to all of your rows called student and then from there use this javascript:
function displayContent(json) {
var len = json.feed.entry.length
var divtag = ''
for (var i = 0; i < len; i++) {
divtag +=
'<div class="student" id="tooltipwrap'+i+'">'+
'<span style="font-size:22px; font-weight:600;">'+
json.feed.entry[i].gsx$studentname.$t +
'<span class="hide" style="font-size:18px; font-weight:300;">'+
json.feed.entry[i].gsx$classlevel.$t +
'</span> '+
'<span id="tooltipside'+i+'">'+
json.feed.entry[i].gsx$gender.$t + '-' +
'</span>'+
'</span>'+
'</div>';
}
document.getElementById('tipswrap').innerHTML = divtag
}
jQuery(document).ready(function($) {
$('.student').each(function() {
if ($(this).text().toLowerCase().indexOf("senior") >= 0)
$(this).addClass('senior');
});
});
Here's a demo
