text string output stops after first space, js/html

I apologize in advance, this is the first Stack Overflow question I've posted. I was tasked with creating a new ADA compliant website for my school district's technology helpdesk. I started with minimal knowledge of HTML and have been teaching myself through w3cschools. So here's my ordeal:
I need to create a page for all of our pdf and html guides. I'm trying to create a somewhat interactable menu that is very simple and will populate a link array from an onclick event, but the title="" text attribute drops everything after the first space and I've unsuccessfully tried using a replace() method since it's coming from an array and not static text.
I know I'm probably supposed to use an example, but my work day is coming to a close soon and I wanted to get this posted so I just copied a bit of my actual code.
So here's what's happening, in example 1 of var gmaildocAlt the tooltip will drop everything after Google, but will show the entire string properly with example 2. I was hoping to create a form input for the other helpdesk personnel to add links without knowing how to code, but was unable to resolve the issue of example 1 with a
var fix = gmaildocAlt.replace(/ /g, "&nb sp;")
//minus the space
//this also happens to break the entire function if I set it below the rest of the other variables
I'm sure there are a vast number of things I'm doing wrong, but I would really appreciate the smallest tip to make my tooltip display properly without requiring a replace method.

function gmailArray() {
var gmaildocLink = ['link1', 'link2'];
var gmaildocTitle = ["title1", "title2"];
var gmaildocAlt = ["Google Cheat Sheet For Gmail", "Google 10-Minute Training For Gmail"];
var gmailvidLink = [];
var gmailvidTitle = [];
var gmailvidAlt = [];
if (document.getElementById("gmailList").innerHTML == "") {
for (i = 0; i < gmaildocTitle.length; i++) {
arrayGmail = "" + gmaildocTitle[i] + "" + "<br>";
document.getElementById("gmailList").innerHTML += arrayGmail;
}
for (i = 0; i < gmailvidTitle.length; i++) {
arrayGmail1 = "";
document.getElementById("").innerHTML += arrayGmail1;
}
} else {
document.getElementById("gmailList").innerHTML = "";
}
}
<div class="fixed1">
<p id="gmail" onclick="gmailArray()" class="gl">Gmail</p>
<ul id="gmailList"></ul>
<p id="calendar" onclick="calendarArray()" class="gl">Calendar</p>
<ul id="calendarList"></ul>
</div>

Building HTML manually with strings can cause issues like this. It's better to build them one step at a time, and let the framework handle quoting and special characters - if you're using jQuery, it could be:
var $link = jQuery("<a></a>")
.attr("href", gmaildocLink[i])
.attr("title", gmaildocAlt[i])
.html(gmaildocTitle[i]);
jQuery("#gmailList").append($link).append("<br>");
Without jQuery, something like:
var link = document.createElement("a");
link.setAttribute("href", gmaildocLink[i]);
link.setAttribute("title", gmaildocAlt[i]);
link.innerHTML = gmaildocTitle[i];
document.getElementById("gmailList").innerHTML += link.outerHTML + "<br>";
If it matters to your audience, setAttribute doesn't work in IE7, and you have to access the attributes as properties of the element: link.href = "something";.

If you add ' to either side of the variable strings then it will ensure that the whole value is read as a single string. Initially, it was assuming that the space was exiting the Title attribute.
Hope the below helps!
UPDATE: If you're worried about using apostrophes in the title strings, you can use " by escaping them using a . This forces JS to read it as a character and not as part of the code structure. See the example below.
Thanks for pointing this one out guys! Sloppy code on my part.

Why am I receiving a NaN on parsing an number in Javascript

I can't find why I'm receiving a NaN for printing a number out with javascript.
The following code I use is repeated elsewhere on the website and works fine.
The URL in question is: http://all-american-gold10.mybigcommerce.com/us-silver-eagles/
My code is as follows:
function setCheckPrice() {
$('.NormalPrice').each(function(key, val) {
var price = $(val).html().replace('$', '').replace(',', '');
var newPrice = parseInt(price) * .03;
var setPrice = Math.floor(price - newPrice);
var credit = '<small style="font-size: 20px !important;"> - credit card price</small>';
var check = '<p><em class="new-price">$' + setPrice +'<small style="font-size: 20px !important;"> - check price</small></em></p>';
$(val).append(credit);
$(val).prepend(check);
})
};
setCheckPrice();
My code takes a number found by a specific class name, does some math and spits in back out with some extra html to go along with it. I've tried to switch the ways I've outputted the code with append, prepend, before & after, but none seem to work? Any reason why this is acting so strange?

The price variable has additional html in it. You should consider having separate elements with a class that contains just the value that you need, and nothing else. As a quick fix, this change:
var price = $(val).val().replace('$', '').replace(',', '').replace(" ","");
get's me a value of 490 for price on that page, which is what you're looking for.

Get text between tags using javascript

I am trying to get prices from between span tags. I would like to have all prices in an array. I cant seem to get it to work, I am guessing my regex is incorrect.
I am looking for any span tags with the class 'amount', the tag has no other attributes set and only has one class. E.g. <span class="amount">£9.99</span>
var prices = resp.fragments['data'].match(/<span class=\"amount\">(.*?)<\/span>/g)
.map(function(val){
return val;
});
Output
[ '£9.99', '£100.00' ]

[ '£9.99', '£100.00' ]
* UPDATE *
Turns out it was an encoding with the ajax response resp.fragments['data'].
I was using regex as it is something I have not really used before in JS and thought I would have a play. I did look at many examples and after about 45 mins with no success I thought a fresh set of eyes would fix it.

Thanks for the helpful comment. Your one of those people if someone asked "Is there is a doctor in the house?", you would stand up and say "Sweet load there are loads of doctors out there".

While a regular expression could work for this, it might be easier to simply select the <span class='amount'> elements and map their innerHTML content to an array via the map() function:
// This would yield an array containing your values
var amounts = Array.prototype.slice
.call(document.querySelectorAll('span.amount'))
.map(function(a){ return a.innerHTML; });
You can see a working example of this demonstrated here.

Simplest method will be to add this to an invisible DOM object and then traverse it via DOM API
var text = '<span class="amount">£9.99</span><span class="amount">£9.99</span>'
//now append it to an DOM object
var wrapperDiv = "<div style='display:none' id='tmpDiv'>" + text + "</div>";
document.body.innerHTML += wrapperDiv;
var elements = document.querySelectorAll( "#tmpDiv amount" );
var output = Array.prototype.slice.call( elements ).map( function(val){
return val.innerText;
})
Another approach could be split the text by <span class="amount"> and get the value after first index
DEMO
var text = '<span class="amount">£9.99</span><span class="amount">£9.99</span>'
var output = [];
text.split('<span class="amount">').forEach( function(val, index) {
if (index > 0 )
{
output.push( val.replace( "</span>", "" ) );
}
});
document.body.innerHTML += JSON.stringify( output, 0, 4 );

You can use this instead.
var prices = document.getElementsByClassName('amount');
var price_array = [];
for (i= 0; i < prices.length; ++i) {
price_array.push(prices[i].innerHTML);
}
document.write(" | " + price_array);
<span class='amount'>£123</span>
<span class='amount'>£3</span>
<span class='amount'>£5</span>
<span class='amount'>£64</span>
You don't need to use regex or jQuery for this.

Calculating a number using a textbox

I've been trying to calculate a number using a number given by a user in a text box. I've been trying to use the following code. But when I try to test it, nothing happens. Is there something I'm missing? And is there a way that I can make the imprint variable global?
<form>
<p>How many products do you want
ingraved?<input id="imprint_amount" name="imprint_amount" type="text"/>
</p>
<p>Names to be Imprinted(one per
line)<TEXTAREA COLS=25 NAME="imprint_text" ROWS=5 WRAP=HARD style="resize:none;"></textarea>
</p>
<input onclick="imprint_price" type="button" value="Finish"/>
<p id="total_cost"></p>
</form>
<script type="text/javascript">
function imprint_price() {
var imprint_cost,
imprint_quality,
imprint_total;
imprint_cost = 10.99;
imprint_quantity = document.getElementById('imprint_amount');
imprint_total = $imprint_cost * parseInt(imprint_quantity, 10);
document.getElementById('total_cost') = "$" + imprint_total;
}
Thanks,
Traci

You will want to use the value property of that input element you are referencing in your variable:
… parseInt(imprint_quantity.value, 10);
For arbitrary HTML elements, you need to use textContent (or innerText to support old IE):
document.getElementById('total_cost').textContent = …;
Assigning to an expression as you did should have thrown a quite accurate exception, check your browser's error console for them.

Change your javascript to:
<script type="text/javascript">
function imprint_price() {
var imprint_cost,
imprint_quantity,
imprint_total;
imprint_cost = 10.99;
imprint_quantity = document.getElementById('imprint_amount').value;
imprint_total = imprint_cost * parseInt(imprint_quantity, 10);
document.getElementById('total_cost').innerHTML = imprint_total;
}
</script>
Working jsFiddle here http://jsfiddle.net/Zt38S/2/

In this line, you'll want to set the innerHTML of the element.
document.getElementById('total_cost').innerHTML = "$" + imprint_total;
This basically sets the text inside the <p></p> to be <p>$x.xx</p>.
And also this line should be
imprint_quantity = document.getElementById('imprint_amount').value;
which retrieves the value from the textbox.
Furthermore, when defining the variables, you wrote "quality". It should be
imprint_quantity,

imprint_quantity = document.getElementById('imprint_amount');
=
imprint_quantity = document.getElementById('imprint_amount').value();
Lemme know if that fixes it, a common enough mistake.

Unable to retrieve values from eBay API response using Javascript

I am trying to build a very simple tool for use at my work. I work for eBay and currently the tools available are cumbersome for the task. We are asked to compare text and images to check that sellers aren't stealing each others content. I am using the eBay Trading API and the sample HTML/CSS/Javascript code given when the developer account was created. Ultimately what I hope to achieve is a simple page that displays two items' photo and description next to each other. However, right now I am simply trying to edit the sample code given to display the start date of the auction.
My question is this: I am trying add a variable who's value is determined by a response from the API. some of these are provided in the sample however, when I add my own var starttime = items.listingInfo.startTime to the function and add the variable to the HTML table none of the data displays including those that displayed prior to my addition. Unfortunately I don't have more than a rudimentary understanding of javascript and so am unsure if I am even properly phrasing this question, let alone getting the syntax of my addition correct. What am I doing wrong?
below is the sample text with my addition of one declared variable (starttime) and one addition to the HTML table
<html>
<head>
<title>eBay Search Results</title>
<style type="text/css">body { font-family: arial,sans-serif;} </style>
</head>
<body>
<h1>eBay Search Results</h1>
<div id="results"></div>
<script>
function _cb_findItemsByKeywords(root)
{
var items = root.findItemsByKeywordsResponse[0].searchResult[0].item || [];
var html = [];
html.push('<table width="100%" border="0" cellspacing="0" cellpadding="3"><tbody>');
for (var i = 0; i < items.length; ++i)
{
var item = items[i];
var title = item.title;
var viewitem = item.viewItemURL;
var starttime = items.listingInfo.startTime;
if (null != title && null != viewitem)
{
html.push('<tr><td>' + '<img src="' + pic + '" border="0">' + '</td>' +
'<td>' + title + '' + starttime + '</td></tr>');
}
}
html.push('</tbody></table>');
document.getElementById("results").innerHTML = html.join("");
}
</script>
<!--
Use the value of your appid for the appid parameter below.
-->
<script src=http://svcs.ebay.com/services/search/FindingService/v1?SECURITY-APPNAME=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&OPERATION-NAME=findItemsByKeywords&SERVICE-VERSION=1.0.0&RESPONSE-DATA-FORMAT=JSON&callback=_cb_findItemsByKeywords&REST-PAYLOAD&keywords=iphone%203g&paginationInput.entriesPerPage=3>
</script>
</body>
</html>"

If you believe listingInfo is an property of individual items, and that it is an object that has the property startTime, then the proper syntax is:
var item = items[i];
var title = item.title;
var viewitem = item.viewItemURL;
var starttime = item.listingInfo.startTime;
You are currently referencing items which is the array of items, not an individual item.
Update
I looked into this via the URL you put in the comments. The solution to this particular problem is this:
var starttime = item.listingInfo[0].startTime;
I hope that helps. Please review the FAQ; Imho this question falls outside the scope of this site (the question is really quite narrow, and not likely to help anyone else). I recommend Mozilla Developer Network as a source for learning more about JavaScript.
