htmx - format date for browser locale - htmx

I've tried the following to format a date in the locale of the browser:
<script>document.write((new Date(2021, 4, 14)).toLocaleString().split(",")[0])</script>
However, based on this question Document.write clears page it seems like it is writing after the document stream is closed, thereby opening a new stream and replacing the content on my page.
Using htmx is there a recommended way of formatting dates to the browser locale?
Is there an htmx tag that allows me to execute this javascript safely?
This is the html I'm using to invoke htmx:
<div hx-get="/open_orders"
hx-trigger="load"
hx-target="this"
hx-swap="outerHTML">
<img class="htmx-indicator"
src="[[=URL('static', 'images/spinner.gif')]]"
height="20"/>
</div>

As you mentioned, document.write() does not play well with htmx. This is true for most front-end libraries/toolkits/frameworks that want to control what is displayed in the browser window.
Instead, there are a number of ways you could do this instead:
Try rendering the time on your server and simply displaying the value via htmx. This library works best when you put the server in charge whenever you can. I would recommend starting with this, if you can, instead of rendering a date via Javascript.
If you really need to update this information on the browser (for instance, to update the display as the data changes, write to a specific DOM element instead:
<span id="time"> </span>
<script>
document.getElementById('time').innerHTML = currentTime();
</script>
You can also hook in to a wide range of events that htmx triggers. This works well if you want to update information on the browser whenever htmx does something -- for instance, you can update the date/time displayed whenever htmx loads a new html fragment into the DOM.

aurelia: properly sanitizing innerHTML-bound data

I am perfectly aware that I can sanitize innerHTML-bound data using:
<div innerhtml.bind="someData | sanitizeHTML"></div>
However, based on my observations, this sanitization only removes <script> tags. It doesn't protect the user from event-driven content such as:
"Hi! I am some HTML-formatted data from the server! <button onclick="getRekt();">Click me for butterflies!</button>"
Is there a better way to prevent ANY type of javascript or event callbacks from being rendered on the element?
The sanatizeHTML value converter is a very simple sanitizer, and only remove the scripts tags. See the code here.
You can create your own value converter with a more complex santizer. Check this answer for more details about how to sanitize html in a browser.
But don't forget to never trust the browser, if you can it's better to sanitize the html in the server side before to send it to the browser to display it.

How to get Inspect Element code using Selenium WebDriver

I'm working in selenium with Firefox browser.
The Html code shown in View Source (CTRL+U) is different from the html code i see when inspecting the elements in Firefox.
When i run the driver.getPageSource() i only get the View source (CTRL + U) codes.
Is there is any way to access the Inspect element code instead of View source code?
I think your question is answered here.
The View Source html is what is sent by the server. I think of it as compile time html, or the initial state of the DOM.
The Inspect Element html could have been updated by ajax responses or javascript so will not necessarily be the same. I think of it as runtime html, or the current state of the DOM.
The GetAttribute() method queries the current DOM element state. You can return a particular html attribute value directly
webElement.GetAttribute("class")
or get the whole html string.
webElement.GetAttribute("innerHTML")
There are some fundamental difference between the markup shown through View Source i.e. using ctrl + U and the markup shown through Inspector i.e. using ctrl + shift + I.
Both the methods are two different browser features which allows users to look at the HTML of the webpage. However, the main difference is the View Source shows the HTML that was delivered from the web server (application server) to the browser. Where as, Inspect element is a Developer Tool e.g. Chrome DevTools to look at the state of the DOM Tree after the browser has applied its error correction and after any Javascript have manipulated the DOM. Some of those activities may include:
HTML error correction by the browser
HTML normalization by the browser
DOM manipulation by Javascript
In short, using View Source you will observe the Javascript but not the HTML. The HTML errors may get corrected in the Inspect Elements tool. As an example:
With in View Source you may observe:
<h1>The title</h2>
Whereas through Inspect Element that would have corrected as:
<h1>The title</h1>
getPageSource() always returns the markup obtained through View Source.

How to handle many bootstrap modals on a single html page

I would have 10 bootstrap buttons on a single html page.
Each button opens a ootstrap modal filled with a html fragmen via an ajax request.
<div class="modal fade" id="myModal"></div>
$('#myModal').modal();
Should I create 10 different divs with 10 different ids? Or even 10 different instances?
var dialogInstance1 = new BootstrapDialog({
title: 'Dialog instance 1',
message: 'Hi Apple!'
});
or
should I create ONE dialog?
I would expect kind of caching problems when I open modal1, then just when I open modal2 I see still for some miliseconds modal1 html fragment from a prvious ajax request.
And how should I create those modals? The samples should this:
$('#myModal').modal();
and the instantiation? This is very confusing.
Can someone please share his experience how to approach with many bootstrap modals?
I would expect kind of caching problems when I open modal1, then just when I open modal2 I see still for some miliseconds modal1 html fragment from a prvious ajax request.
Assuming you're referring to data-remote's caching, you will probably be able to disable that in Bootstrap v3.2.0 (see https://github.com/twbs/bootstrap/pull/13183/ ).
However, I'd still recommend against using data-remote since it doesn't give you much control. It:
doesn't provide or easily let you do any error handling
doesn't give any "loading..." indication
forces you have to generate modal HTML on the server side (as opposed to, e.g., returning JSON from the server and using client-side templating)
IMO, you should:
include just one instance of the blank modal markup
setup your own click event handlers on the buttons that summon your modal
initiate the AJAX request in your click event handler
use client-side templating to generate a corresponding modal using the results of the request
use $(...).modal() or $(...).modal('show') (depends on how your templating works) to show the modal after the templating completes

Work around to POST requirement

I need to be able give users a link to my site with a parameter that will control their experience on the destination page, but, of course, Moqui does not allow parameters to be passed as a GET transaction. What are ways that I can work around that? It needs to be something that can be sent in an email, via sms and audibly.
An error message would be helpful know exactly what you are running into, but it sounds like the constraint to mitigate XSRF attacks.
The error message for this situation explains the issue and the recommended solution: "Cannot run screen transition with actions from non-secure request or with URL parameters for security reasons (they are not encrypted and need to be for data protection and source validation). Change the link this came from to be a form with hidden input fields instead."
You can pass URL parameters to screens to be used in code that prepares data for presentation, but not to transitions for code that processes input. The solution is to use a hidden form with a link or button to submit the form (that can be styled as a link or button or however you want). This is slightly more HTML than a plain hyperlink with URL parameters, but not a lot more and there are examples in various places in the Moqui itself.
If you are using an XML Screen/Form you can use the link element to do this with the #link-type attribute set to "hidden-form" or "hidden-form-link" (which just uses a hyperlink styled widget instead of a button styled one). If the #link-type attribute is set to "auto" (which is the default) it will use a hidden-form automatically if link goes to a transition with actions.
In plain HTML one possible approach looks something like this:
<button type="submit" form="UserGroupMemberList_removeLink_0">Remove</button>
<form method="post" action=".../EditUserGroups/removeGroup" name="UserGroupMemberList_removeLink_0">
<input type="hidden" name="partyId" value="EX_JOHN_DOE">
<input type="hidden" name="userGroupId" value="ADMIN">
</form>
Note that the button element refers to the form to submit, so can be placed anywhere in the HTML file and the form element can be placed at the end or anywhere that is out of the way (to avoid issues with nested forms which are not allowed in HTML).

DHTML - Change text on page using input field

I need to create a code to change an example text to a user-defined value when the user types in an input field (Similar to the preview field when writing a question on Stack Overflow).
This needs to be achieved without the use of HTML5 or Flash as the users will be running IE8, not all will have Flash plug-ins installed.
As such I have started by looking at DHTML to achieve the desired effect. Currently I can change the example text when a user types in the input field but only to a pre-defined value ("Example" in the code below), how should I edit this code to display the user-defined value?
JS
function changetext(id)
{
id.innerHTML="Example";
}
HTML
<form>
Content:<input type="text" id="input" onkeyup="changetext(preview)" />
</form>
<p id="preview">No content found</p>
You need to have something like this in the function:
function changetext(id){
var info = document.getElementById('input').value();
id.innerHTML = info;
}
This js is not fully correct. I would highly recommend you start using a javascript library like jQuery. It makes this a menial task.
Edited:
jQuery will work in IE8 just fine. in jQuery you will not need to attach js to your input. The code would look like this.
$('#input').click(function(){
$('#preview).html(this.val());
});
It is a lot cleaner and doesnt have js in the html.
