my sapUI5 app only jumps once into my print method

this is my very first question on Stackoverflow. I am currently developing a print function in my sap ui5 app to print out certain UI controls. I've got the function from here: http://embed.plnkr.co/jjyEPa1updkjBiNZqumS/preview
However, during runtime, when I click on the print button, my app only jumps to the method once and executes it correctly (to print). But after that, I can press the printbutton as often as I want, nothing happens and I can't find out why.
what the method does: i replace the body with a temporary body, which only contains the elements to be printed and execute window.print(). afterwards i insert the original body content again. Of course I use the UI controls to grab the HTML tags.
onPrintChart: function(oEvent){
var oTarget = this.getView(),
sTargetId = oEvent.getSource().data("targetId");
if (sTargetId) {
oTarget = oTarget.byId(sTargetId);
}
if (oTarget) {
var $domTarget = oTarget.$()[0],
sTargetContent = $domTarget.innerHTML,
sOriginalContent = $(document.body)[0].innerHTML;
$(document.body)[0].innerHTML = sTargetContent;
window.print();
$(document.body)[0].innerHTML = sOriginalContent;
} else {
jQuery.sap.log.error("onPrint needs a valid target container [view|data:targetId=\"SID\"]");
}
}

I managed to do it in a different, more elegant way without using a temporary body. I used CSS to hide all irrelevant elements (display: none) and keep only the relevant element for printing.
Apparently ui5 hung up when replacing the original body temporarily with another body. I noticed that ALL buttons didn't work anymore, not only the print button.

JavaScript only being called once in Squarespace

I have some custom JavaScript on my SquareSpace site that manipulates Product titles beyond what you can do with SquareSpace's default style editor. It works when initially loading the page (https://www.manilva.co/catalogue-accessories/) but if you click on any of the categories on the left, the styling resets to the default.
I'm assuming the JavaScript is being overwritten by the SquareSpace style, but I can't figure out why. Perhaps I'm calling the function in the wrong place?
Any suggestions would be helpful.
Thanks!
Current code:
document.querySelectorAll(".ProductList-filter-list-item-link".forEach(i=>i.addEventListener("click", function()
{
var prodList = document.querySelectorAll("h1.ProductList-title");
for (i = 0, len = prodList.length; i < len; i++)
{
var text = prodList[i].innerText;
var index = text.indexOf('-');
var lower = text.substring(0, index);
var higher = text.substring(index + 2);
prodList[i].innerHTML = lower.bold() + "<br>" + higher;
});

The source of your problem is that your template has AJAX loading enabled. There are currently a couple generally-accepted ways to deal with this as a Squarespace developer:
Disable AJAX loading
Write your javascript functions in a
manner that will run on initial site load and whenever an "AJAX load" takes place.
Option 1 - Disable AJAX:
In the Home Menu, click Design, and then click Site Styles.
Scroll down to Site: Loading.
Uncheck Enable Ajax Loading.
Option 2 - Account for AJAX in Your JS
There are a number of ways that developers approach this, including the following, added via sitewide code injection:
<script>
window.Squarespace.onInitialize(Y, function() {
// do stuff
});
</script>
or
<script>
(function() {
// Establish a function that does stuff.
var myFunction = function() {
// Do stuff here.
};
// Initialize the fn on site load.
myFunction();
// myFunction2(); , etc...
// Reinit. the fn on each new AJAX-loaded page.
window.addEventListener("mercury:load", myFunction);
})();
</script>
or
<script>
(function() {
// Establish a function that does stuff.
var myFunction = function() {
// Do stuff here.
};
// Initialize the fn on site load.
myFunction();
// Reinit. the fn on each new AJAX-loaded page.
new MutationObserver(function() {
myFunction();
// myFunction2(); , etc...
}).observe(document.body, {attributes:true, attributeFilter:["id"]});
})();
</script>
Each of those works for most of the latest (at time of writing) templates most of the time. Each of those have their advantages and disadvantages, and contexts where they do not work as one might expect (for example, on the /cart/ page or other "system" pages). By adding your code within the context of one of the methods above, and ensuring that the code is of course working in the desired contexts and without its own bugs/issues, you will have your code run on initial site load and on each AJAX page load (with some exceptions, depending on the method you use).

Your problem is the page does not reload when clicking a button on the left, just some elements are removed, added and replaced. The changed elements will not be restyled. You will need to re-run your JavaScript after one of those buttons is clicked. Perhaps something like this:
document.querySelectorAll(
".ProductList-filter-list-item"
).forEach(
i=>i.addEventListener(
"click", ()=>console.log("hello")
)
)
where you replace console.log("hello") with whatever resets your formatting.

div is filled dynamically with html after main page loads- how to determine it has been loaded

I inherited a project where a page is loaded, then code attached to that page fills in a div with dynamically generated html - it basically fills an existing div with a html string.
This string contains links to images, etc.
I want to tell when all the images, etc have loaded- I cannot seem to get any jQuery standard checks
to work - ie I have tried attaching $(window).load() after the dynamic stuff has been inserted.
I am wondering if I should write $(window).load() dynamically as well, or if there is any other
method- ie $("#thediv").load (doesn't seem to work. I cannot query all the new html for image tags, etc-
too much stuff is being put in.

The $(window).load() doesn't work for dynamic content as far as I know. You can use the .load event for each image separated. Here's an example:
var container = $("<div> ... Stuff ... </div>");
var images = container.find('img');
var imageIdx = 0;
images.load(function(){
imageIdx++;
if (imageIdx == images.length){
callback();
}
});
Where callback() is the function that runs after all images where loaded.

From my comment: window load applies to the initial page load only. Not dynamic loading of content within it. Attach load handlers to each loaded image element and count them.
This is the shortest version I could come up with for you:
// After HTML load finishes
var img = 0;
var imgCount = $("#thediv img").load(function(){
if (++img == imgCount){
// We are done loading all images!
}
}).length;

$(window).ready() only applies to the content within the HTML file and you can only use load to attach an onload event handler to a specific image (not a container), something like this might work for you.
window.ImageLoadHandled = false;
window.ImageLoadCount = 0;
function ImageLoadHandler() {
// guard against calling this function twice
if(window.ImageLoadHandled) return;
window.ImageLoadHandled = true;
// All images have loaded || timeout expired...
}
$("#myAjaxedDiv img").load( function() {
window.ImageLoadCount++;
if( window.ImageLoadCount == $("#myAjaxedDiv img").length ) {
// all images in #myAjaxedDiv have loaded
ImageLoadHandler();
}
});
// if images haven't loaded after 5 seconds, call the code
setTimeout( ImageLoadHandler, 5000 )
The only problem with this is that if an image fails to load for whatever reason, the code will never be hit, which is quite risky. To counteract this I'd recommend creating a setTimeout() method to call your code after a few seconds timeout in-case there is a problem loading images (client or server side) and I've also taken #TrueBlueAussie's correction into account in the edit.
Your alternative is to preload the images with your HTML page

Load javascript in html within content pane

I have an html file that I want to be loaded from various pages into a dijit.contentpane. The content loads fine (I just set the href of the contentpane), but the problem is that javascript within the html file specified by href doesn't seem to be executed at a consistent time.
The final goal of this is to load an html file into a contentpane at an anchor point in the file (i.e. if you typed in index.html#tag in order to jump to a certain part of the file). I've tried a few different methods and can't seem to get anything to work.
What I've tried:
1.
(refering to the href of the dijit.contentpane)
href="page.htm#anchor"
2.
(again, refering to the href of the dijit.contentpane -- didn't really expect this to work, but decided to try anyways)
href="#anchor"
3. (with this last try inside the html specified by href)
<script type="text/javascript">
setTimeout("go_to_anchor();", 2000);
function go_to_anchor()
{
location.href = "#anchor";
}
</script>
This last try was the closest to working of all of them. After 2 seconds (I put the delay there to see if something in the dijit code was possibly loading at the same time as my javascript), I could see the browser briefly jump to the correct place in the html page, but then immediately go back to the top of the page.

Dojo uses hashes in the URL to allow bookmarking of pages loaded through ajax calls.
This is done through the dojo.hash api.
So... I think the best thing you can do is use it to trigger a callback that you write inside your main page.
For scrolling to a given position in your loaded contents, you can then use node.scrollIntoView().
For example, say you have a page with a ContentPane named "mainPane" in which you load an html fragment called "fragment.html", and your fragment contains 2 anchors like this :
-fragment.html :
Anchor 1
<p>some very long contents...</p>
Anchor 2
<p>some very long contents...</p>
Now say you have 2 buttons in the main page (named btn1 and btn2), which will be used to load your fragment and navigate to the proper anchor. You can then wire that up with the following javascript, in your main page :
<script type="text/javascript">
require(['dojo/on',
'dojo/hash',
'dojo/_base/connect',
'dijit/layout/BorderContainer',
'dijit/layout/ContentPane',
'dijit/form/Button'],
function(on, hash, connect){
dojo.ready(function(){
var contentPane = dijit.byId('mainPane');
var btn1 = dijit.byId('btn1');
var btn2 = dijit.byId('btn2');
btn1.on("Click", function(e){
if (!(contentPane.get('href') == 'fragment.html')) {
contentPane.set("href", "fragment.html");
}
hash("anchor1");
});
btn2.on("Click", function(e){
if (!(contentPane.get('href') == 'fragment.html')) {
contentPane.set("href", "fragment.html");
}
hash("anchor2");
});
// In case we have a hash in the URL on the first page load, load the fragment so we can navigate to the anchor.
hash() && contentPane.set("href", "fragment.html");
// This callback is what will perform the actual scroll to the anchor
var callback = function(){
var anchor = Array.pop(dojo.query('a[href="#' + hash() + '"]'));
anchor && anchor.scrollIntoView();
};
contentPane.on("DownloadEnd", function(e){
console.debug("fragment loaded");
// Call the callback the first time the fragment loads then subscribe to hashchange topic
callback();
connect.subscribe("/dojo/hashchange", null, callback);
});
}); // dojo.ready
}); // require
</script>

If the content you're loading contains javascript you should use dojox.layout.ContentPane.

Google related bar - how to keep from showing up on my website

A new "google related" bar shows up at the bottom of my website. It displays links to my competitors and other things like maps, etc. It is tied in with users using the google toolbar. If anyone has any ideas on how I can disable from displaying on my web side I would sure appreciate it.

Taken from http://harrybailey.com/2011/08/hide-google-related-bar-on-your-website-with-css/
Google inserts an iframe into your html with the class .grelated-iframe
So hiding it is as simple as including the following css:
iframe.grelated-iframe {
display: none;
}

Google removed div and frame names and put everything to important so original answer no longer works on my site. We need to wait for the iframe to be created and then hide it by classname. Couldn't get .delay to work, but this does...today anyway.
$(document).ready(function() {
setTimeout(function(){
$(‘.notranslate’).hide();},1000);
});

Following javascript code tries to find the google related iframe as soon as the window finishes loading. If found, it is made hidden, else an interval of one second is initialized, which checks for the specified iframe and makes it hidden as soon as it is found on page.
$(window).load(function (){
var giframe = null;
var giframecnt = 0;
var giframetmr = -1;
giframe = $("body > iframe.notranslate")[0];
if(giframe != null)
$(giframe).css("display", "none");
else
giframetmr = setInterval(function(){
giframe = $("body > iframe.notranslate")[0];
if(giframe != null) {
clearInterval(giframetmr);
$(giframe).css("display", "none");
} else if(giframecnt >= 20)
clearInterval(giframetmr);
else
giframecnt++;
}, 1000);});

Find the parent DIV element that contains the stuff in the bar. If it has an id or name attribute, and you can control the page CSS then simply add a rule for the element, i.e. if you see something like
<div id="footer-bar-div".....
then add a CSS rule
#footer-bar-div {display:none ! important}
This will not work if the bar is inside an iframe element, but even in that case you should be able to hide it using javascript, but you will need to find the name/id of the frame, i.e.:
var badFrame = document.getElementById('badFrameId').contentWindow;
badFrame.getElementById('footer-bar-div').style.display='none';
if the frame has a name, then instead you should access it with:
var badFrame = window.frames['badFrameName']
There is also a chance that the bar is generated on-the-fly using javascript. If it is added to the end of the page you can simply add a <noscript> tag at the end of your content - this will prevent the javascript from executing. This is an old trick so it might not always work.
