How do I use Javascript to delay visibility of a text box and then hide another box after the first becomes visible

Im very new to this and have reviewed other posts similar to this question. However, I'm finding that those solutions don't work for me.
Background: I'm working in Wix's Velo platform for Javascript. (forgive me if that's not the right technical terminology here)
My goal: When my website home page loads, I want one of the text boxes on the page (#text45) to NOT be visible until 5 seconds have passed. Then, when box #text45 is visible, I want another plain box (#box2) to turn to hidden.
I have found some examples like the one below: (not all code has been pasted and I realize some elements like div1 would need to change to my specific element names)
document.getElementById("div1").style.visibility = "visible";
}
setTimeout("showIt()", 5000);
However, I get an error code: Cannot find name 'document'. Do you need to change your target library? Try changing the 'lib' compiler option to include 'dom'.
When researching this, I found out that Velo cannot access the dom and elements can only be accessed via "$w".
Would someone be kind enough to set me in the right direction on how to accomplish the "goal" above? I would really appreciate it! Thank you in advance.

Here's how you would do it. Note, that it's good practice to change the IDs of your elements to more descriptive names, but I've stuck with the names you provided in your question.
Start by setting #text45 to hidden in using the Properties & Events panel.
Then use this code (note that your page might already have an onReady. If it's there an you're not using it yet, delete all the code on the page and replace it with this):
$w.onReady( () => {
setTimeout(() => {
$w('#text45').show();
$w('#box2').hide();
}, 5000)
} );

jQuery .attr Not Working Properly, Miss-Retrieving Links

This is a page I'm currently working on as a project
$(function() {
$(".modal-launcher, #modal-background").click(function() {
$(".modal-content, #modal-background").toggleClass("active");
$(".vid-1i").attr("src", "link1");
$(".vid-2i").attr("src", "link2");
$(".vid-3i").attr("src", "link3");
$(".vid-4i").attr("src", "link4");
$(".vid-5i").attr("src", "link5");
$(".vid-6i").attr("src", "link6");
$(".vid-7i").attr("src", "link7");
$(".vid-8i").attr("src", "link8");
//$('html').toggleClass('active').css('top', -(document.documentElement.scrollTop) + 'px');//
});
});
above the actual links are replaced just to display a quick idea of the bad jQuery.
In it, I am attempting to create my own popup launcher for videos; however, I am having trouble using jQuery to replace the "" src of an iframe element to a YouTube link. I am unable to figure out why the jQuery is not working. I understand that the jQuery is, of course, working properly, and that it is me who has written the code incorrectly, but here I am asking if anyone is able to figure out what it is I've done wrong, or what can be changed to make it work.
For some reason, the last video in the jQuery list is always the one retrieved.
Understand that the images are missing from the page due to them being local files and not network locations. Clicking above the captions that read like "Match One" will have the "intended" result, regardless if the image is showing or not.

Coming back to this and understanding more of JavaScript and jQuery, my problem was simply misunderstanding the code. In order to do something like this, one function per link would be more suitable.
function video1()
{
$("#popup, #modal-background").toggleClass("active");
$("#popup").prop("src", "https://www.youtube.com/embed/7h1s15n74r3all1nk");
document.getElementById('scroll').style.cssText ='overflow:hidden';
}
complementary html would look like this:
<div onclick="video1()"></div>
The previous code would run each line, effectively setting the last link as the source of the element. The new code is button independent, ensuring only one link belongs to each button.

Inline Editing But Instance Doesn't Exist

I have my own custom non-jQuery ajax which I use for programming web applications. I recently ran into problems with IE9 using TinyMCE, so am trying to switch to CKeditor
The editable text is being wrapped in a div, like so:
<div id='content'>
<div id='editable' contenteditable='true'>
page of inline text filled with ajax when links throughout the site are clicked
</div>
</div>
When I try to getData on the editable content using the examples in the documentation, I get an error.
I do this:
CKEDITOR.instances.editable.getData();
And get this:
Uncaught TypeError: Cannot call method 'getData' of undefined
So I figure that it doesn't know where the editor is in the dom... I've tried working through all editors to get the editor name, but that doesn't work-- no name appears to be found.
I've tried this:
for(var i in CKEDITOR.instances) {
alert(CKEDITOR.instances[i].name);
}
The alert is just blank-- so there's no name associated with it apparently.
I should also mention, that despite my best efforts, I cannot seem to get the editable text to have a menu appear above it like it does in the Massive Inline Editing Example
Thanks for any assistance you can bring.

UPDATE:
I'm showing off my lack of knowledge here, but I had never come across "contenteditable='true'" before, so thought that because I was able to type inline, therefore the editor was instantiated somehow... but now I'm wondering if the editor is even being applied to my div.
UPDATE 2:
When the page is loaded and the script is initially called, the div does not exist. The editable div is sent into the DOM using AJAX. #Zee left a comment below that made me wonder if there is some other command that should be called in order to apply the editor to that div, so I created a button in the page with the following onclick as a way to test this approach: (adapted from the ajax example)
var editor,html='';config = {};editor=CKEDITOR.appendTo('editable',config, html );
That gives the following error in Chrome:
> Uncaught TypeError: Cannot call method 'equals' of undefined
> + CKEDITOR.tools.extend.getEditor ckeditor.js:101
> b ckeditor.js:252
> CKEDITOR.appendTo ckeditor.js:257
> onclick www.pediatricjunction.com:410
Am I headed in the right direction? Is there another way to programmatically tell CKEditor to apply the editor to a div?
UPDATE 3:
Thanks to #Reinmar I had something new to try. The most obvious way for me to test to see if this was the solution was to put a button above the content editable div that called CKEDITOR.inlineAll() and inline('editable') respectively:
<input type='button' onclick=\"CKEDITOR.inlineAll();\" value='InlineAll'/>
<input type='button' onclick=\"CKEDITOR.inline('editable');\" value='Inline'/>
<input type='button' onclick=\"var editor = CKEDITOR.inline( document.getElementById( 'editable' ) );\" value='getElementById'/>
This returned the same type of error in Chrome for all three buttons, namely:
Uncaught TypeError: Cannot call method 'equals' of undefined ckeditor.js:101
+ CKEDITOR.tools.extend.getEditor ckeditor.js:101
CKEDITOR.inline ckeditor.js:249
CKEDITOR.inlineAll ckeditor.js:250
onclick
UPDATE 4:
Upon further fiddling, I've tracked down the problem being related to json2007.js, which is a script I use which works with Real Simple History (RSH.js). These scripts have the purpose of tracking ajax history, so as I move forward and back through the browser, the AJAX page views is not lost.
Here's the fiddle page: http://jsfiddle.net/jasonsilver/3CqPv/2/

When you want to initialize inline editor there are two ways:
If element which is editable (has contenteditable attribute) exists when page is loaded CKEditor will automatically initialize an instance for it. Its name will be taken from that element's id or it will be editor<number>. You can find editors initialized automatically on this sample.
If this element is created dynamically, then you need to initialize editor on your own.
E.g. after appending <div id="editor" contenteditable="true">X</div> to the document you should call:
CKEDITOR.inline( 'editor' )
or
CKEDITOR.inlineAll()
See docs and docs.
You can find editor initialized this way on this sample.
The appendTo method has different use. You can initialize themed (not inline) editor inside specified element. This method also accepts data of editor (as 3rd arg), when all other methods (CKEDITOR.inline, CKEDITOR.replace, CKEDITOR.inlineAll) take data from the element they are replacing/using.
Update
I checked that libraries you use together with CKEditor are poorly written and cause errors you mentioned. Remove json2007.js and rsh.js and CKEditor works fine.

OK, so I have tracked down the problem.
The library I was using for tracking Ajax history and remembering commands for the back button, called Real Simple History, was using a script called json2007 which was intrusive and extended native prototypes to the point where things broke.
RSH.js is kind of old, and I wasn't using it to it's full potential anyway, so my final solution was to rewrite the essential code I needed for that, namely, a listener that watched for anchor (hash) changes in the URL, then parsed those changes and resubmitted the ajax command.
var current_hash = window.location.hash;
function check_hash() {
if ( window.location.hash != current_hash ) {
current_hash = window.location.hash;
refreshAjax();
}
}
hashCheck = setInterval( "check_hash()", 50 );
'refreshAjax()' was an existing function anyway, so this is actually a more elegant solution than I was using with Real Simple History.
After stripping out the json2007.js script, everything else just worked, and CKEditor is beautiful.
Thanks so much for your help, #Reinmar... I appreciate your patience and effort.

Unable to fire Javascript Event using Watir and how to find element which does not have any attribute

I am new to watir and ruby. I have two questions for which I am unable to get the solution. I have googled and have still not got working solution. Any assistance will be of great help.
Question 1 : How to fire Javascript event.
The html is as mentioned below.
img onclick="javascript:previousScreen(1);" alt="Back" src="/WSWeb/images/someimage.gif"/
I have tried most of the solutions likes, fireevent etc. which was on Google. Please write me a piece of code which will work for the mentioned scenario.
Question 2 : How to click or validate if the element exists for html mentioned below.
Scenario 1 : This is the html text
input onclick="history.go(-1)" type="button" value="Back"/
Scenario 2 : <center> under this-> Text - Login Id. This is all what is present. This is a cell in a table which is in a frame. Please write me a code for both the scenarios.

Well, if you have two questions, post two questions. :)
If the page is public, post a link to it, that is the best way for us to help.
Regarding javascript events, see How to find out which JavaScript events fired?
You can click the button like this:
browser.button(:value => "Back").click
For the center element, you will have to provide more HTML. I am not sure what you need to do with it.

First of all, as to selecting elements that do not have an attribute, see the answers (all three) to this SO question asked a little while back: Accessing an element with no attributes in Watir
With regard to your specific examples/question here: If you refer to the watir wiki's listing of methods supported for selecting elements you will see that an image element (img tag) can be selected by the src. So for your first thing, just do this
browser.image(:src => '/WSWeb/images/someimage.gif').click
if for some reason the click method does not work, then you could try firing the onclick event directly
browser.image(:src => "/WSWeb/images/someimage.gif").fire_event('onclick')
For the second part, you will also notice that value can be used to select 'button' elements which includes input tags of type=button. thus to see if the button is there
browser.button(:value => 'Back').exists? #(will return true or false)
For the second scenario there, Watir does not currently support selecting by most formatting tags like center, so you would need to look at what element contained that text. You say it is a table cell (td) inside a frame (which I don't know how to identify since you provide no html) and if that is the case and I am understanding it right then
browser.frame(:how => 'what').cell(:text => 'Login Id').exists?
should work (presuming the text is actually 'Login Id' and not 'Login ID')

Click a button made from div with JavaScript?

In Google+, the button that is used to post a comment is made from a div:
<div role="button" id=":1vq.post" class="d-s-r tk3N6e-e tk3N6e-e-qc" aria-disabled="false" style="-webkit-user-select: none; " tabindex="0">Post comment</div>
I think I can click it with:
document.getElementById(":1vq.post").click();
But it says that the element have no attribute click, and I found that onclick is null. So how could I click the button with JavaScript?

EDIT: After a chat with wong2 who started this question and a lot of failed guesses for what this question is really about (the question is quite poorly written), what they are trying to do is to write a Greasemonkey userscript to make the enter key press the Post Comment button in Google+ streams. Since I don't have an invite into Google+ yet, I can't even see the relevant code so not much I can do. This question is not about putting anything related to Google+ in your own site - it's about trying to use Greasemonkey to modify the behavior of Google's site in your own browser.
Earlier attempts to help:
id=":1vq.post" is not a legal CSS id name. You can't use the ":" character in a selector name. This causes multiple issues because not only is it not a legal character, but it's also a meaningful character in the CSS selector syntax. So, I see that you have two issues.
First, your selector logic is not working. Second, as others have said, you can't just assign to click in this way with plain javascript (e.g. no framework).
If you change your selector logic to work correctly, you can get it to work properly (using jQuery) like this:
<div role="button" id="aPost" class="d-s-r tk3N6e-e tk3N6e-e-qc" aria-disabled="false" style="-webkit-user-select: none; " tabindex="0">Post comment</div>
$("#aPost").click(function() {
alert("I was clicked.");
});
And, you can see it in action in this jsFiddle: http://jsfiddle.net/jfriend00/Yfnc7/. Click Run and then click on the Post Comment.

click() applies only to elements like input and button.
http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-2651361
onclick would appear in 1990 and not at Google. They should be using addEventListener.
Try to set a breakpoint and see what function is called on click. Then call the function directly.
To trigger a click event handler one can use createEvent plus dispatchEvent.
See example: http://jsfiddle.net/DzVg9/
Note, that Google Plus may actually be using mousedown or mouseup events.

Are you sure you are acurately selecting the button with $(":1vq.post")? Perhaps you need to change it to $("#:1vq.post") or something like that (I'm not sure how JQuery handles the : and . characters).
