How to add value in href from JSON

i'm trying to create table from JSON.
I need to add a value from JSON in tag
function drawProjectRow(rowProject) {
var row = $("<tr/>")
$("#projectListTable").append(row);
row.append($("<td><a href = MY URL PLUS VALUE from rowProject.key> " + rowProject.key + "</a></td>"));
}

Here you can see the value is being rendered ,
var rowProject=2;
console.log("<td><a href ='MY URL"+rowProject+"'> " + rowProject + "</a></td>")
You can do that
row.append("<td><a href ='MY URL"+rowProject.key+"'> " + rowProject.key + "</a></td>");
Or you can follow template literals

Coolest way to handle this in JavaScript
"<td><a href = MY URL PLUS VALUE from rowProject.key> " + rowProject.key + "</a></td>"
to
`<td>${rowProject.key}</td>`;

Missing ) after argument but only for a long string

I am using JavaScript to fill a <div> tag with other <div>s. It has been working until I changed an identifier used inside a onclick event. The old identifier (index) was just a small number from 0-1000, but the new identifier (id) is a uuid.v4() generated string that looks like this:
f5ec8170-e75c-4a93-9997-1a683b7d2e00
I have the exact same code for index and the id. But whenever I click on the button which is suppose to activate the function call with the id as an argument it gives me:
Missing ) after argument
Which does not happen when I click on the button which does the same thing with index as an argument instead of id.
My code:
var id = messages[i].id;
var index = 0;
var newElement =
'<div class="fullMessage" id="fullRightMessage' + i + '">'+
'<h6 class="textMessage">' + messages[i].comment + '</h6>' +
'<button class="likeButtonMessage" onclick="likeClicked(right, ' + index + ', 1);">LIKE</button>' +
'<button class="dislikeButtonMessage" onclick="likeClicked(right, ' + id + ', -1);">DIS</button>' +
'<h4 id="scoreright' + i + '" class="messageScore">' + messages[i].score + '</h4>' +
'</div>'

You do not enclose the uuid with quotation marks. Before it worked because your id was a clean integer which doesn't need them.
Exchange the line with id to
'<button class="dislikeButtonMessage" onclick="likeClicked(right, \'' + id + '\', -1);">DIS</button>' +

Your previous ID was interpreted as an int, which is the reason why it worked.
Your new ID is a string, requiring you to enclose it in quotation marks:
onclick="likeClicked(right, \'' + id + '\', -1);"
This is because this is not valid code:
likeClicked(right, f5ec8170-e75c-4a93-9997-1a683b7d2e00, -1)

Why won't my button delete?

document.getElementById("roster").innerHTML += "<button onclick=\"doSomething()\">+</button>\n" +
"<span onClick=\'$(this).remove();" +
"$(this).prev().remove();" +
"oiDelete(\"" + str + "\");" +
"removeCost(\"" + str + "\");" +
"selectedItem(\"" + str + "\");" +
"frDelete(\"" + str + "\")\';>" +
str + "</span><br>";
So this goes inside a Javascript function I'm working on. What it's supposed to do is create clickable text regions (spans) that disappear when clicked as well as generate a button right before the clickable text that is supposed to be removed when the text is clicked. I can get the text to disappear just fine, but I can't get the darn button to go away.
The code being generated is:
<button onclick="doSomething()">+</button>
<span onclick="$(this).remove();
$(this).prev().remove();
oiDelete("Marneus Calgar");
removeCost("Marneus Calgar");
selectedItem("Marneus Calgar");
frDelete("Marneus Calgar")" ;="">Marneus Calgar</span>
Why is it generating ="" at the end of the opening span tag? why is the button not deleting properly? is $(this).prev().remove() not the correct option?

If we cast aside best practice, this is the working code.
document.getElementById("roster").innerHTML += "<button onclick=\"doSomething()\">+</button>\n" +
"<span onClick=\'$(this).prev().remove();" +
"$(this).remove();" +
"oiDelete(\"" + str + "\");" +
"removeCost(\"" + str + "\");" +
"selectedItem(\"" + str + "\");" +
"frDelete(\"" + str + "\")\'>" +
str + "</span><br>";
The reason why your code doesn't work is because you are removing the span which has onclick function on the fly. It means it can't reach the $(this).prev().remove() bit.
I hope it makes sense.
If you want to go an extra mile, you should put $(this).remove(); after the frDelete() function. Otherwise those 4 functions that you call will never be called.

You messed up quotation marks and of course - call self-remove code at the end (!)
And one tip - encapsulate these additional function in one procedure - it help to keep code cleaner.
document.getElementById('roster').innerHTML += '<button onclick=\'doSomething()\'>+</button>' +
'<span onClick="doCalls(); $(this).prev().remove(); $(this).remove(); ">' + str + '</span><br>';

Javascript creating a li element and assigning text to data-attribute is being truncated

In javascript I am creating a li element as per below which contains only the problem I am seeing.
The data-videoUrl is showing the full url, so all good there.
The issue is the entry.link and entry.title, while debugging, I verified the strings are within quotes. i.e. "This is a pod cast." The data-videoTitle and data-videoDesciption are being truncated though. i.e. "This" will show from the previous example.
I'm not sure what is occuring in the latter two data assignments as I've verified the text is not double quoted etc. What is occuring with the html5 data elements? I can provide a more complete example if needed.
var podItem = document.createElement("li");
podItem.innerHTML = entry.title
+ "<a data-videoUrl=" + entry.link + " "
+ "data-videoTitle=" + entry.title + " "
+ "data-videoDescription=" + entry.contentSnippet + " "
+ "</a>";
document.getElementById("podCastList").innerHTML += podItem.innerHTML;
Here is a the html being generated.
<a data-videourl="http://rss.cnn.com/~r/services/podcasting/studentnews/rss/~3/d3y4Nh_yiZQ/orig-sn-060614.cnn.m4v" data-videotitle="CNN" student="" news="" -="" june="" 6,="" 2014="" data-videodescription="For" our="" last="" show="" of="" the="" 2013-2014="" school="" year,="" cnn="" takes="" a="" look="" back,="" ahead,="" and="" at="" stories="" making="" ...="" <=""></a>
I'm sure there's something I'm not fully understanding. Why would the first data element get the text correctly, and the next two data elements break up the text as in: [data-videotitle="CNN" student="" news=""]. The text is a straight forward sentence quoted i.e. "CNN student news..."
Why would videoUrl work correctly and the other two not?

You need to add some quotes around the attributes...
podItem.innerHTML = entry.title
+ "<a data-videoUrl=\"" + entry.link + "\" "
+ "data-videoTitle=\"" + entry.title + "\" "
+ "data-videoDescription=\"" + entry.contentSnippet + "\" "
+ "</a>";
You'll also want to make sure you escape any quotes that are inside the attributes as well.

Javascript Parameter Passing Not Working

The code dynamically creates a listview which works but i want to make it so when a listview item is clicked it sends the a url paramater to another method. When i set a paramater it doesnt alert the paramater, but when i give no parameter it works.
var output =
"<li onclick='openURL()'><h3> Module Code: " +
results.rows.item(i).module
+ "</h3>Room: "
+ results.rows.item(i).room +
"</li>";
The above works - No parameter in openURL();
var output =
"<li onclick='openURL('" + results.rows.item(i).url + "')'><h3> Module Code: " +
results.rows.item(i).module
+ "</h3>Room: "
+ results.rows.item(i).room +
"</li>";
The above doesnt work - I have done alert(results.rows.item(i).url) and it has a value.
function openURL(url) {
alert("opening url " + url);
}
Could someone explain what i'm doing wrong, i've been trying to solve the problem for hours.
Cheers!

You are using single quotes to open the HTML attribute, you can't use it as JavaScript String because you'll be closing the HTML attribute, use double quotes:
var output =
"<li onclick='openURL(\"" + results.rows.item(i).url + "\")'><h3> Module Code: " +
results.rows.item(i).module
+ "</h3>Room: "
+ results.rows.item(i).room +
"</li>";
