Link from one page to drop down in page two

I'm trying to create an <a> link in html page 1 that takes the user to html page 2. After html page 2 loads, I want a drop down function to execute. Essentially it is a link from html page 1 to drop down in html2.
I am not very good with javascript, but I've tried anything I could find so far and nothing works. The link between the pages works, but I cannot get the drop down function to execute on load of html page 2.
Any help would be greatly appreciated
HTML Page 1
<a class="link2index" href="index2.html#test" onclick ="f();return false;">Read more about technology hubs in South Africa</a>
<script>
function f(){
testwindow = window.load("index2.html#test"); //this is working to load but not to load the dropdown
//testwindow.addEventListener('click', myFunction38()); not working
//window.onload = myFunction38 ()
//testwindow.addEventListener('load', myFunction38()){
//document.getElementById("myDropdown38").classList.toggle("show");}; not working
//window.open('index2.html');
//window.somefunction = myFunction38(){
//document.getElementById("myDropdown38").classList.toggle("show");} not working
}
</script>
HTML Page 2 to where I'm targeting
<div class="dropdown">
<button id="test" onclick="myFunction38()" class="dropbtn">Cape Town</button>
<div id="myDropdown38" class="dropdown-content">
<a href="#">
<img src="media/capetown.jpg" alt="South Africa">
Cape Town-based Labsorganises digital and entrepreneurship bootcamps, and provides an investment of up to $20,000 for every social enterprise developed through their program.
</a>
</div>
</div>
<script>
function myFunction38() {
document.getElementById("myDropdown38").classList.toggle("show");
}
</script>

Basically you can use the window.onload function to run some JavaScript to dynamically add html to your body and show a "drop-down".
But since html2 can be reached in other ways(like bookmark or copy/paste into browser) and not just through hyperlink inside html1, you could also append some query string or fragment in html2 when it is loaded from html1 (append it to the href of a tag). Inside the onload function you can then check if the same exists and decide whether or not to show drop-down.
I will not be giving a code since the functionality is vaguely defined in the question. But this should help you solve it on your own.

Mimicking a click on a button inside an iframe. No errors, but no response

The code is currently set up in this way:
<div class="tradingview-widget-container">
<iframe src="https://theurl.com"></iframe>
Within the iframe (which has no ID assigned), there are buttons set up like this:
<div class="tv-tabs__scroll-box">
<div class="tv-tabs__tab js-timeframe-tab" data-timeframe="1d">1d</div>
<div class="tv-tabs__tab js-timeframe-tab" data-timeframe="1m">1m</div>
<div class="tv-tabs__tab js-timeframe-tab" data-timeframe="3m">3m</div>
</div>
The default option selected is not my desired selection, I want to be able to automatically have the script load the "1d" chart. Any clues on why my function isn't working?
jQuery(function($) {
$('.tradingview-widget-container > iframe').contents().find('[data-timeframe="1d"]').trigger("click")
});
I'm not getting an error, but the chart view is remaining the same. Do I need to set a POST request as well?
For reference, I am trying to implement this with this widget: https://www.tradingview.com/widget/market-overview/
Thanks in advance!

As #Rory McCrossan had said, the problem was not the JS query itself, but a security feature implemented by TradingView.

template insertion in a editor

Describing a scenario:
I am going through the code mentioned below.B asically I am trying to figure out how to program so that
when a user clicks on "Use Template" button , it gets inserted into an editor.
Page 1:
There are lot of templates present
When a user clicks on the "Use Template" button on , it gets inserted into an editor that is present in
the next page (Page 2).
Please find the code snippet below for the first two templates I am going through:
<div id="templatesWrap">
<div class="template" data-templatelocation="templateone" data-templatename="Template ONE" data-templateid="" >
<div class="templateContainer">
<span>
<a href="https://app.abc.com/pqr/core/compose/message/create?token=c1564e8e3cd11bc4t546b587jan31&sMessageTemplateId=templateone&sHubId=&goalComplete=200" title="Use Template">
<img class="thumbnail" src="templatefiles/thumbnail_010.jpg" alt="templateone">
</a>
</span>
<div class="templateName">Template ONE</div>
<p>
Use Template
</p>
</div>
</div>
<div class="template" data-templatelocation="templatetwo" data-templatename="Template TWO" data-templateid="" >
<div class="templateContainer">
<span>
<a href="https://app.abc.com/pqr/core/compose/message/create?token=c1564e8e3cd11bc4t546b587jan31&sMessageTemplateId=templatetwo&sHubId=&goalComplete=200" title="Use Template">
<img class="thumbnail" src="templatefiles/thumbnail_011.jpg" alt="templatetwo">
</a>
</span>
<div class="templateName">Template TWO</div>
<p>
Use Template
</p>
</div>
</div>
And so on ....
How does the link "https://app.abc.com/pqr/core/compose/message/create?token=c1564e8e3cd11bc4t546b587jan31&sMessageTemplateId=templatetwo&sHubId=&goalComplete=200" is inserting the template into the editor which is located on the next page? I haven't understood the token part and lot's of ID's present in the link
which I think are thereason behind inserting the template.
Has anyone come across such link before? Please advise.
Thanks
MORE CLARIFICATIONS:
Thanks for your answer.It did help me somewhat. I have few more questions:
Basically, I am using TinyMCE 4.0.8 version as my editor. The templates, I am using are from here:
https://github.com/mailchimp/email-blueprints/blob/master/templates/2col-1-2-leftsidebar.html
Some questions based on "Tivie" answer.
1) As you can see in the code for "2col-1-2-leftsidebar.html " it's not defined inside <div> tags unlike you defined it in <div> tags. Do you think that I can still
use it using "2col-1-2-leftsidebar.html " name?
2)I believe,for explanation purpose, you have included
`"<div contenteditable="true" id="myEditor">replaced stuff</div>`
and
<button id="btn">Load TPL</button>
<script>
$("#btn").click(function() {
$("#myEditor").load("template.html");
});
</script>
in the same page. Am I right? ( I understand you were trying to make an educated guess here, hence
just asking :) )
In my case, I have a separate page, where I have written code for buttons just like you wrote in editor.html like the following:
<button id="btn">Load TPL</button>. My button is defined inside <div class="templateContainer">.
Also, my templates are defined in a separate folder. So, I will have to grab the content(HTML Template), from
that folder and then insert into TinyMCE 4.08 editor. (Looks like two step process). Could you elaborate
on how should I proceed here?
More Question As of Dec 27
I have modifier my code for the template as follows:
<div class="templateName">Template ONE</div>
<p>
Use Template
</p>
Please note, I have added an additional id attribute for the following purpose.
If I go by the answer mentioned in the Tivia's post, is the following correct?
<script>
$("#temp1").click(function() {
$("#sTextBody").load("FolderURL/template.html");
});
</script>
My editor is defined like the following on Page 2 (Editor Page).
<div class="field">
<textarea id="sTextBody" name="sTextBody" style="width:948px; max-width:948px; height: 70%"></textarea>
</div>
I am confused, like, the script tag I have defined is in Page 1 where I have defined all the template related code
and the Page 2(Editor) page is a different page. It's simply taking me to Editor page (Page 2) and hence not working.
Please advise where I am wrong.
Thanks
MORE QUESTIONS AS of Jan 2
The problem Iam facing is as follows. Basically, for first template , I have the following code.
Code Snippet #1 where "Use "Template" button is present:
<div class="templateName">Template ONE</div>
<p>
Use Template
</p>
And the function suggested in the answer is as follows:
Code Snippet #2 where Editor is present:
<script>
$("#temp1").click(function() {
$("#sTextBody").load("FolderURL/template.html");
});
</script>
Since, I believe I first need to reach to that page after user clicks on "Use Template" button, where the editor is located, I have defined Code Snippet #1 on Page 1 and have defined the Code Snippet #2 and <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> as the very first two script tags in the Page 2 ( Editor Page). But still when I click on "User Template" button on Page 1, it's just letting me to next page and not loading the template into the editor.
Am I doing something wrong here? Please advise.
P.S. The problem I feel is somehow the click function on Page 2 is not getting activated with the temp1 id button mentioned on Page 1.
Thanks

Well, one can only guess without having access to the page itself (and it's source code). I can, however, make an educated guess on how it works.
The URL params follows a pattern. First you have a token that is equal in all templates. This probably means the token does not have any relevance to the template mechanism itself. Maybe it's an authentication token or something. Not relevant though.
Then you have the template identification (templateOne, templateTwo, etc...) followed by a HubId that is empty. Lastly you have a goalComplete=200 which might correspond to the HTTP success code 200 (OK).
Based on this, my guess would be that they are probably using AJAX on the background, to fetch those templates from the server. Then, via JScript, those templates are inserted into the editor box itself.
Using JQuery, something like this is trivial. here's an example:
template.html
<div>
<h1>TEST</h1>
<span>This is a template</span>
</div>
editor.html
<!DOCTYPE HTML>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
</head>
<body>
<div contenteditable="true" id="myEditor">
replaced stuff
</div>
<button id="btn">Load TPL</button>
<script>
$("#btn").click(function() {
$("#myEditor").load("template.html");
});
</script>
</body>
</html>
Edit:
1) Well, since those templates are quite complex and include CSS, you probably want to keep them separated from you editor page (or the template's CSS will mess up your page's css).
However, since you're using TinyMCE, it comes with a template manager built in, so you probably want to use that. Check this link here http://www.tinymce.com/wiki.php/Configuration:templates for documentation.
2) I think 1 answers your question but, just in case, my method above works for any page in any directory, provided it lives on the same domain. Example:
<script>
$("#btn").click(function() {
$("#myEditor").load("someDirectory/template.html");
});
</script>
I recomend you check this page for the specifics on using TinyMCE http://www.tinymce.com/wiki.php/Configuration:templates
EDIT2:
Let me explain the above code:
$("#btn").click(function() { });
This basically tells the browser to run the code inside the brackets when you click the element with an id="btn"
$("#myEditor").load("someDirectory/template.html");
This is an AJAX request (check the documentation here). It grabs the contents of someDirectory/template.html and places them inside the element whose id="myEditor"

Passing data from tab 1 to tab 2

I'm new to stackoverflow and I came here because I couldn't find clear answers to my problems with html and javascript.
I'm wanting to display an HTML page with 3 buttons and the buttons will execute 3 scripts onClick. I need tab#1 to talk to tab#2 to execute the code but I'm stuck on how I go about doing that - here's my HTML code:
<!DOCTYPE html>
<html>
<body>
<!-- START STAGE 1 -->
<script>
function stage1()
{
// Here I want to open up a new tab so I'd do:
window.open('http://webpage.com', '_blank');
}
</script>
<!-- START STAGE 2 -->
<script>
function stage2()
{
// From here, I want to execute some JavaScript to the new tab I've opened
}
</script>
<!-- START STAGE 3 -->
<script>
function stage3()
{
// Again, I want to execute another script on the new tab I've opened
}
</script>
<button type="button" onClick="stage1()">STAGE1</button>
<hr />
<button type="button" onClick="stage2()">STAGE2</button>
<hr />
<button type="button" onClick="stage3()">STAGE3</button>
</body>
</html>
I'd be very appreciated if someone could re-write this code and leave a space in the 3 's for my code to go to be executed on tab#2 from tab#1.
Thank you in advance! - Sorry, I'm a bit of a noob haha.
Cheers,

It won't be straightforward, but I think you could do it with a "proxy" page that displays the intended site (Twitter) in an iframe and runs the scripts you need when you pass a parameter in the address (e.g., proxy.htm?action=step2 ) or even use a separate dedicated proxy page (proxy2.htm) for each step.
But in order for this to work, I believe you need to use a custom name for the target of your anchor links (a target="proxy_twitter"), so all links open in the same tab.
A possible issue would be that the 2nd tab would reload the proxy page on each click, but maybe this can be avoided by changing the parameters to be hashtags (proxy.htm#action=step2).
I myself don't have any experience with this mechanism, but I've seen it used on some sites.

calling an external script and .load jquery conflict

I'm pretty sure this is another DOH! facepalm questions but as designer and not a programmer I need some help getting it right.
What I have is an index file calling local .html files via jQuery .load. Just like this:
(some tabs functionality not relative here - thus the link target call)
Lightbox</li>
<div id=lightbox">
<div class="load">
<script type="text/javascript">
$('.load').load('examples/lightbox.html');
</script>
</div>
</div>
I also have an external .js file that has a bunch of functions that handles some lightboxes among other things. Standard <script src="js/typography.js" type="text/javascript"></script>
Which contains:
$(document).ready(function(){
$(".open-lightbox").on("click", function(){
$('.lightbox').css('display','block');
});
$('.close-lightbox').click(function(){
$('.lightbox').css('display','none');
});
});
My problem is that if the externally called .html file has any elements dependent on the .js file ie. the lightbox popup it doesn't work.
something like :
LightBox Link
<div class="lightbox">
lightbox content
Close
</div>
If i move the html code right to the index page instead of the .load, no problem, same if I moved the JS as an inline <script>...</script> rather than calling it extrenally. Works fine in both cases.
My spidey sense tells me this has something to do with my function and .load not executing in the order I need them to, but my javascript copy/paste skills only go this far.
Can anyone tell me if I can make this combination work? I'd really appreciate it.
EDIT
Maybe I explained my self poorly so let me try and post a better example.
If my index code is as followed everything works: My lightbox pops up as intended.
<li>Link to open Tab Content</li>
<div id="thistabid">
<--Tab Content below-->
<div class="somehtmlpage-load">
LightBox Link
<div class="lightbox">
lightbox content
Close
</div>
</div>
<--End Tab Content-->
</div>
When the said tab is clicked the content inside "thistabid" show up. Whatever that content may be.
Now if i do :
<li>Link to open Tab Content</li>
<div id="thistabid">
<--Tab Content below-->
<div class="somehtmlpage-load">
<script type="text/javascript">
$('.somehtmlpage-load').load('examples/lightbox.html');
</script>
</div>
<--End Tab Content-->
</div>
The lightbox doesn't work. The content of lightbox.html is
LightBox Link
<div class="lightbox">
lightbox content
Close
</div>
Same as the html in the 1st example where everything works. The only difference it's being jQuery loaded rather than hard coded.
What I mean by "if the externally called .html file has any elements dependent on the .js file ie. the lightbox popup" is that if the html is part of the externally called file then the lightbox function isn't working. If it's hard coded it pops up like intended.
On 1st glance the .on seems like should be the solution but most likley my implementation of it is off the mark :/

The 'on' or the 'live' function needs to be applied through an element that exists on the page. Generally some parent of the actual element is used. Can you try something on the following lines with the correct references to the elements on your page:
<li>Link to open Tab Content</li>
<div id="thistabid">
<--Tab Content below-->
<div class="somehtmlpage-load">
<!--leave tab empty for now -->
</div>
<--End Tab Content-->
</div>
<script>
(function(){
$('.somehtmlpage-load').load('examples/lightbox.html');
//live or on needs to be applied to an element that exists on th page
$('#thistabid').on('click', '.open-lightbox', function(){
$('.lightbox').css('display','block');
});
$('#thistabid').on('click', '.close-lightbox', function(){
$('.lightbox').css('display','none');
});
})();
</script>

There seems to be a race condition between your load() and document ready.
To address this you'll need to:
either wait for the load() to complete before you attach the click events
or attach the click to the container of your load() step and use event delegation.
See this page and this other one for more information on how to use on() for delegation.
The code would look like this:
$(".somehtmlpage-load").on("click", ".open-lightbox", function(){
$('.lightbox').css('display','block');
});

Using a SSI solved my problem. I was trying to keep it all Local Drive friendly but it seemed to be causing more problems than anticipated.
Pick your favorite dev environment...I didn't run into any conflicts on either.
ASP - <!--#include file = "examples/lightbox.html" -->
PHP - <?php include 'examples/lightbox.html';?>
Just in case someone else runs into a similar problem.
