I am working on a small code snippet.
The Issue:
I want to have a couple of buttons, that on click load content into a div, using ajax.
I can get it working absolutely fine, with say images, and text. But cannot load with css and js.
Example: the index page:
<input type="button" onclick="example_ajax_request()" value="Click Me!" /> | <input type="button" onclick="example_ajax_request2()" value="Or Me!" />
<div id="example-placeholder">
<p>Placeholding text</p>
</div>
<script type="text/javascript">
function example_ajax_request() {
$('#example-placeholder').html('<p><img src="images/loader.gif" width="220" height="19" /></p>');
$('#example-placeholder').load("fat.html");
}
</script>
<script type="text/javascript">
function example_ajax_request2() {
$('#example-placeholder').html('<p><img src="images/loader.gif" width="220" height="19" /></p>');
$('#example-placeholder').load("joined_today.html");
}
</script>
The page joined_today.html is a full blown webpage ( which contains a div element ) only, and shaows AMCHARTS. Which obviously utilise js inc Raphael.
Anyhoo, the issue arises, from any webpage with headers, html and body tags. The script above doesnt render these.
So what am i doing wrong. Seemingly, we can only load into div id example_placeholder content that doesnt include JS, or CSS
Is there a better way.
Essentially our scenario is this ( I want to avoide iFrames )
We have web page, and a content div, with 3 buttons above the div.
On click of each button, the div gets loaded with a chart ( using amcharts js version )
On click of another button , another chart gets loaded inplace of the first chart, etc etc
Perhaps I am going about this wrong, any help appreciated.

You need to insert the <style>, <link> and <script> tags in another place, e.g. <head> or end of <body> with something like:
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'somescript.js';
document.getElementsByTagName('head')[0].appendChild(script);
One potential problem is to check whether a file (css or javascript) has been inserted. You may need to maintain a global list to check whether a file is already included.
Take a look at this source for "DOM-based On-Demand JavaScript".
Easy way to do this: load the js and CSS files on the parent page.

I'm trying to include my Adsense code from a file called sda.html located in the home folder of the server.
I'm using this code to include it:
<div w3-include-html="../../sda.html" class="section_title text-center"></div>
from this source: https://www.w3schools.com/howto/howto_html_include.asp
but idk I feel there's something wrong.
btw my site is only HTML and js, so if there is any other better option I'll be glad to hear it.
I also checked this one down:
<!--#include virtual="/menu.shtml" -->
but I didn't use it, since I have no clue how my next server will operated. so I skip it.
and this one here:
<object data="../../sda.html"></object>
I prefer this one, but I have no control of the look of it, I couldn't center or anything
the smaller the code the better it is.
Does sda.html contains only adsense code or whole part of the page?
The includeHTML function from w3school is not very good. I suspect the issue you are having is that that function uses innerHTML to set content and innerHTML doesn't execute <script> tags with content: check "Security considerations" on MDN page.
To workaround this you can do the following: remove <script> tags from sda.html and then, once you imported HTML run window.adsbygoogle.push({}) for each new ad unit. Example:
Add adsbygoogle.js tag in of your page:
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
Insert ad into a div with id div-with-ad.
const divWithAd = document.querySelector('#div-with-ad');
divWithAd.innerHTML = `
<ins class="adsbygoogle"
style="display:block; text-align:center;"
data-ad-format="fluid"
data-ad-layout="in-article"
data-ad-client="ca-pub-0123456789101112"
data-ad-slot="9876543210"></ins>
`;
adsbygoog.push({});
Let me preface by saying this is all in relation to a Wordpress page. My knowledge of JS is lacking at best and the concept of installing/loading/enqueueing a function on one area of the site and then calling that function in another area of the site is a something that makes sense to me in my head but is very new to me in practice and might need a little explaining.
I have two separate javascript files that I would like to load on a single page, but toggle visibility/display of either based on radio button input. The JS is provided by a 3rd party and is offsite. Their provided code is this:
<script src="https://toolkit.rescuegroups.org/j/3/FzemP6HU/toolkit.js"></script>
and
<script src="https://toolkit.rescuegroups.org/j/3/4ANRW3x8/toolkit.js"></script>
Each file presents a separate set of filtered results from their database. How can I incorporate both onto a page but only have one or the other showing based on a radio button form input? I would like the page to start off with nothing visible (hopefully giving time for both JS to load in the background while the user selects an option) and then show one or the other depending on what they selected.
You can see a single one of these in action at http://pricelesspetrescue.org/adoptable-dogs/. I'm trying to incorporate the use of an additional file on that same page based on input from the user and only showing one or the other rather than both.
I have tried to manage the following
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js'></script>
<script type='text/javascript'>
function displayForm(c) {
if (c.value == "2") {
jQuery('#claremontdogContainer').toggle('show');
jQuery('#chdogContainer').hide();
}
if (c.value == "1") {
jQuery('#chdogContainer').toggle('show');
jQuery('#claremontdogContainer').hide();
}
};
</script>
<label>Please select a location to view:</label>
<form>
<input value="1" type="radio" name="formselector" onClick="displayForm(this)"></input>Chino Hills
<input value="2" type="radio" name="formselector" onClick="displayForm(this)"></input>Claremont
</form>
<div style="display:none" id="chdogContainer">
<script src="https://toolkit.rescuegroups.org/j/3/FzemP6HU/toolkit.js"></script>
<script type="text/javascript">
</script>
</div>
<!-- If I uncomment this second block the whole thing breaks
<div style="display:none" id="claremontdogContainer">
<script src="https://toolkit.rescuegroups.org/j/3/4ANRW3x8/toolkit.js"></script>
<script type="text/javascript">
</script>
</div>
-->
This gets pretty close to what I need. The problem I have is the second script load seems to conflict with the functions they provide in the script. It will display the initial result but does not carry any of the functionality that it should have. http://pricelesspetrescue.org/test-page/ Nothing is clickable inside those results and should be.
Been searching through various similar posts and the wordpress codex and...and...I just haven't been able to come up with anything that seems close enough to what I'm looking for to make the answer click in my head.
Edit: It seems that if I only load one of the scripts in either what I have above or the suggested answer below, all functionality is present when loaded. It's the loading of the second toolkit script that is breaking the page. I'm guessing one would need to be loaded then unloaded before loading the second for it to work. Any ideas?
The toolkit.js file you linked adds some common scripts to the DOM (via document.write function, which is not a good solution - see here: http://www.jameswiseman.com/blog/2011/03/31/jslint-messages-document-write-can-be-a-form-of-eval/), then populates an array (toolkitObjects) with a series of variables that are custom per file and finally loads some other scripts.
It also seems that each file loads a div with a specific class containing all the pets, and each div is identifiable by a specific class ( "rgtk-SOMEID" ) and therefore can be shown/hidden via javascript.
Here is an example of what you can obtain using the div class:
http://jsbin.com/loneyijuye/edit?html,output
I have a contenteditable div where you type javascript which gets outputted into an empty script tag.
<div contenteditable="true" id="script-generator"></div>
<div id="save-script">Save</div>
<script type="text/shorthand" id="script">
</script>
So you write your script in the div, click save and I have some JS which gets the html of the contenteditable div and adds it to an empty script tag.
$('#save-script').click(function() {
var script = $('#script-generator').html();
$('#script').html(script);
});
So far this works. But the generated script has no effect. The browser must not recognise the script because it wasn't there on page load? How do I make the script take effect without reloading the page?
Note: The type/shortand on the script is because I'm using a plugin which converts shortand words into actual Javascript. So the user would just need to write shorthand into the contenteditable div, and the plugin would convert that to JS. This might be adding to the problem?
I don't think it works to modify an existing <script> element. If you want the script to be executed you need to add a new element.
$('#save-script').click(function() {
var script = $('#script-generator').html();
$("#script").text(script);
ShortHand.parseScripts();
});
Correct - you need to create the script tag to have it execute after load.
$('head').append($('<script />', {html: script}));
...which means you can remove your empty script tag.
I have set up a test that's similar to what you have been looking for. Take a look and see if that helps.
Working Demo
Test code:
<div id="script" style="display:none">
alert(4+4);
</div>
<input id="sLoad" type="button" value="Load/Execute Script" />
$('#sLoad').click(function(){
//You may want to append to the head
$('<script/>').append( $('#script').html() ).appendTo('#script');
});
I have the following piece of Javascript:
//Clear out container
var container = document.getElementById("buy");
while (container.lastChild)
{
container.removeChild(container.lastChild);
}
and further down, the piece of HTML on which it operates:
<div id="buy" class="itemGroup" />
<canvas id="drawArea" width="200" height="200">
Your browser does not support HTML5 Canvas.
</canvas>
However, the Javascript code removes the canvas, unless the buy div uses start and end tags i.e.
<div id="buy" class="itemGroup">
</div>
Why is this? I thought the two, from an XML point of view, are equivalent? Using Chrome 29.0.1547.76 m on Windows 7.
Thanks in advance!
This is not a more complete answer than the comments already given per se, but I just can't add a comment to your post. Anyway, there are some tags which are not self closing and 'div' is one of them - which actually makes sense if you think about it. Semantically speaking, why are you making a 'division' if there's nothing in it?
Another tricky one is 'script'. Even if you are linking to an external script file in your page, you cannot use
<script type="text/javascript" src="example.js" />
this just doesn't work. Another one is 'textarea'. This renders any html after it useless!
<textarea cols="5" rows="5" />
Take a look at some other ones: http://xahlee.info/js/html5_non-closing_tag.html
I have been searching about this subject now for quite a few days. And could not find a working or conclusive answer.
What I want to do, is to simply display the (styled) summary of the latest blog entry (from the blog page on my own site) in a div container on the front page of my site (which is not my blog). All active links of that mirrored blog entry ideally lead to the appropriate section of my blog page. That is however not a must, as long as the entire entry can link to the blog page.
Each blog entry summary on the blog summary page has a unique ID, sorted by numbers (e.g. unique-ID-51 (latest) unique-ID-50 (the one before) etc.)
I was thinking of doing so with the document.getElementById JS command.
I would have to point the JS function to a relative location (../blog_folder/blog_summary.html) with maybe the .window.location.assign
command, than grab the (styled) contents of the latest element and display that on my front page.
But I have no idea how that code would look in reality. Can you point me in the right direction?
Thank you !!!!!!!

You could add jQuery to your page and use a simple construction:
$('.result-container').load('path/to/your/file.html #id_of_element_to_fetch');
An example chunk of code:
...
<body>
<div class="result-container">There will be your content from some file.</div>
<p>
<a class="result-loader" href="#"></a>
<script type="text/javascript">
$(".result-loader").click(function() {
//Replace path/to/your/file.html and #id_of_element_to_fetch with appropriate values
$('.result-container').load('path/to/your/file.html #id_of_element_to_fetch');
return false;
});
</script>
</p>
</body>
...
And that string somewhere inside the <head> tag:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.min.js"></script>
An example chunk of code with an autostart feature:
...
<body>
<div class="result-container">There will be your content from some file.</div>
<p>
<a class="result-loader" href="#"></a>
<script type="text/javascript">
$(document).ready(function() { //Launches the code below right after the initialization event
//Replace path/to/your/file.html and #id_of_element_to_fetch with appropriate values
$('.result-container').load('path/to/your/file.html #id_of_element_to_fetch');
return false;
});
</script>
</p>
</body>
...
I assume you are using a hidden iframe?
This for example will thet the height of the style.. there are other things in the style
this.container.getElementsByTagName("YOUuniqueID")[0].style.(STYLE)
But you have to put an unique ID in the iframe
Try and use the built in debuggers in IE or Chrome to find what you want...
You can take a look at this for maybe some more info(its for cross domain) but there could be something taht helps you. You might even consider using jquery to access that data.
