Called Upon Client Browsing Specifically Onpaste Image Copying Tutorial

Yesterday’s Called Upon Client Browsing Onpaste Image Copying Tutorial had us adjusting …

• a pre-existing iframe onload event scenario in our changed audio_card.htm Audio Card … and for today we have …
• create a new iframe onload event (via new onload=”checkit(this);” inline HTML onto the iframe HTML coding) scenario in our changed audio_card.htm Image Flipping and Flopping web application

… optional, but potential, use of image copying and pasting via the dual purpose (unchanged from yesterday) local file browsing HTML and Javascript inhouse helper …


var twaconto=null, twacontoiurl=null, twacontojurl=null;

if (twacontojurl) {
if ((twacontojurl.innerHTML + twacontojurl.title).indexOf('data:') == 0) {

Called Upon Client Browsing Onpaste Image Copying Tutorial

As promised at yesterday’s Client Browsing Onpaste Image Copying Tutorial, today, we start looking further than …

• yesterday’s “standalone” incarnation of our now potentially dual purpose “browsing and pasting” inhouse client browsing web application … to, today …
• “called upon” incarnation of our inhouse client browsing web application

… and, as we suspected, today’s first look was pretty salutary in proving “no one paradigm size fits all” with the number of scenarios a “called upon” incarnation of our inhouse client browsing web application can throw up.

Where we think the inhouse client browsing web application for this new “paste” functionality can flourish can be via what we like to call “client pre-emptive iframe” Javascript logic back at the caller, where we extend the code for that HTML iframe’s onload event …

take a new relevant photograph (on an iPhone, for instance) … and then easily …

… upload? Aren’t we worried about the iPhone device end of …

1. getting the image off the Camera app …
2. and then referencing in the Photos app …
3. via a long hover and choosing the Copy option

… will just fall upon deaf ears as far as our MacBook Air web browser use of the “One Image Website” webpage goes?

Well, read this “if an iPhone is connected to a MacBook Air can the copy buffer of the iPhone be transferred to the copy buffer of the MacBook Air?” ask …

Yes, if an iPhone is connected to a MacBook Air—or even just nearby—the copy buffer (clipboard) of the iPhone can be transferred to the copy buffer of the MacBook Air. Apple calls this feature Universal Clipboard.

It allows you to copy text, images, photos, and videos on your iPhone and instantly paste them onto your Mac (or vice versa).

Cute, huh?! If on the same network, and close, the iPhone and MacBook Air do not even need an Apple White Lead connection, necessarily, though we noticed it sped up the process!

One Image Website Onpaste Uploading Hashtagging Tutorial

You guessed it! Yesterday’s One Image Website Onpaste Uploading Tutorial‘s work was working just within the realms of those “first webpages” occurring within the “One Image Website” project paradigm, but that we needed to pass onto subsequent webpages this “new image uploaded” list as ….

• hashtagged data … but also …
• argumented data (ie. ? and & arguments) for those “first webpages” occurring within the “One Image Website” project paradigm …

… the reason being that document.referrer cannot be used to glean hashtagged data.

To most, it is still “undercover” trying out our “still at the Guinea Pig upload functionality thinking stage” Street Art “One Image Website” project.

Previous relevant One Image Website Onpaste Uploading Tutorial is shown below.

One Image Website Onpaste Uploading Tutorial

The onpaste event referencing work of the recent Using Document Writeln Onpaste Tutorial set us to thinking about the unwieldy nature of our “One Image Website” series of photographic projects ability to, on the fly, these days …

• take a new relevant photograph (on an iPhone, for instance) … and then easily …
• get some functionality on the “One Image Websites” (our Guinea Pig, here, being our Street Art project) to accept either …
  1. graphical image Copy into buffer via some Edit->Select All, Edit->Copy (eg. within an Image Editor desktop application) (combination) option Edit->Paste^d into a new HTML span contenteditable=true onpaste and onblur savvy events “uploading” helper … or …
  2. right click at first webpage (of one of these “One Image Website” projects) to get to a prompt window that can accept a data URI the likes of which Google Image Search (say, of “clipart”)->right click->Copy Image Address could glean for you as a representation of an image

Where’s the security and moderation here? Any upload operation needs to worry about that, huh?! Well, we limit it via IP address at this stage, in our Guinea Pig start to proceedings, and will monitor over time.

Let’s start, codewise with the pretty well self contained PHP block of code that is new for this work …

Using Document Writeln Onpaste Tutorial

Regarding yesterday’s Using Document Writeln Primer Tutorial you might wonder …

Why involve either/both textarea and div (contenteditable=true) elements as “containers” of content?

Well, with yesterday’s starting onblur (just) event gambit, it’s a very pertinent question, but, today, we introduce onpaste event work, and involving this event with the div element can have it distinguishing itself, able to accept graphical (eg. image) content. For example, the user can have their cursor placed into the div element and have been in an image editor having Edit->Select All^ed and Edit->Copy^ed graphical content, then that can be Edit->Paste^d into the div as graphical content.

As you might imagine, this opens a Pandora’s Box of possibilities regarding image sizing, but we apply inline CSS styling …


style='object-fit:contain;width:100%;height:100%;'


… to the img data URI^ed element within the div element that happens when graphical content is pasted into it, so that the graphical data is unlikely to spill too far outside the div bounds, assuming only one image is pasted, that is.

So feel free to try a changed using_writeln.html first draft Using (Document) Writeln web application for you to try yourself.

The other day we stumbled on some advice leading us to use …


document.writeln([html-content]);


… rather than our usual “go to” …


document.write([html-content]);

Called Upon Client Browsing Onpaste Image Copying Tutorial

As promised at yesterday’s Client Browsing Onpaste Image Copying Tutorial, today, we start looking further than …

• yesterday’s “standalone” incarnation of our now potentially dual purpose “browsing and pasting” inhouse client browsing web application … to, today …
• “called upon” incarnation of our inhouse client browsing web application

… and, as we suspected, today’s first look was pretty salutary in proving “no one paradigm size fits all” with the number of scenarios a “called upon” incarnation of our inhouse client browsing web application can throw up.

Where we think the inhouse client browsing web application for this new “paste” functionality can flourish can be via what we like to call “client pre-emptive iframe” Javascript logic back at the caller, where we extend the code for that HTML iframe’s onload event …

One Image Website Onpaste Uploading Device Copying Tutorial

Further to yesterday’s One Image Website Onpaste Uploading Hashtagging Tutorial you may be wondering about our original gambit statement wondering if regarding …

take a new relevant photograph (on an iPhone, for instance) … and then easily …

… upload? Aren’t we worried about the iPhone device end of …

1. getting the image off the Camera app …
2. and then referencing in the Photos app …
3. via a long hover and choosing the Copy option

… will just fall upon deaf ears as far as our MacBook Air web browser use of the “One Image Website” webpage goes?

Well, read this “if an iPhone is connected to a MacBook Air can the copy buffer of the iPhone be transferred to the copy buffer of the MacBook Air?” ask …

Yes, if an iPhone is connected to a MacBook Air—or even just nearby—the copy buffer (clipboard) of the iPhone can be transferred to the copy buffer of the MacBook Air. Apple calls this feature Universal Clipboard.

It allows you to copy text, images, photos, and videos on your iPhone and instantly paste them onto your Mac (or vice versa).

Cute, huh?! If on the same network, and close, the iPhone and MacBook Air do not even need an Apple White Lead connection, necessarily, though we noticed it sped up the process!

Given the “smarts” at this end, today, we turned to …

• argumented data (ie. ? and & arguments) for those “first webpages” occurring within the “One Image Website” project paradigm …

To most, it is still “undercover” trying out our “still at the Guinea Pig upload functionality thinking stage” Street Art “One Image Website” project.

One Image Website Onpaste Uploading Tutorial

The onpaste event referencing work of the recent Using Document Writeln Onpaste Tutorial set us to thinking about the unwieldy nature of our “One Image Website” series of photographic projects ability to, on the fly, these days …

• take a new relevant photograph (on an iPhone, for instance) … and then easily …
• get some functionality on the “One Image Websites” (our Guinea Pig, here, being our Street Art project) to accept either …
  1. graphical image Copy into buffer via some Edit->Select All, Edit->Copy (eg. within an Image Editor desktop application) (combination) option Edit->Paste^d into a new HTML span contenteditable=true onpaste and onblur savvy events “uploading” helper … or …
  2. right click at first webpage (of one of these “One Image Website” projects) to get to a prompt window that can accept a data URI the likes of which Google Image Search (say, of “clipart”)->right click->Copy Image Address could glean for you as a representation of an image

Where’s the security and moderation here? Any upload operation needs to worry about that, huh?! Well, we limit it via IP address at this stage, in our Guinea Pig start to proceedings, and will monitor over time.

Let’s start, codewise with the pretty well self contained PHP block of code that is new for this work …

… and then there is some new “fetch” and Ajax rich HTML and Javascript as per …

… that is “undercover” to most trying out our Street Art “One Image Website” project.

Using Document Writeln Onpaste Tutorial

Regarding yesterday’s Using Document Writeln Primer Tutorial you might wonder …

Why involve either/both textarea and div (contenteditable=true) elements as “containers” of content?

Well, with yesterday’s starting onblur (just) event gambit, it’s a very pertinent question, but, today, we introduce onpaste event work, and involving this event with the div element can have it distinguishing itself, able to accept graphical (eg. image) content. For example, the user can have their cursor placed into the div element and have been in an image editor having Edit->Select All^ed and Edit->Copy^ed graphical content, then that can be Edit->Paste^d into the div as graphical content.

As you might imagine, this opens a Pandora’s Box of possibilities regarding image sizing, but we apply inline CSS styling …


style='object-fit:contain;width:100%;height:100%;'


… to the img data URI^ed element within the div element that happens when graphical content is pasted into it, so that the graphical data is unlikely to spill too far outside the div bounds, assuming only one image is pasted, that is.

So feel free to try a changed using_writeln.html first draft Using (Document) Writeln web application for you to try yourself.

The other day we stumbled on some advice leading us to use …


document.writeln([html-content]);


… rather than our usual “go to” …


document.write([html-content]);


And so we wrote a “proof of concept” using_writeln.html first draft Using (Document) Writeln web application for you to try yourself.
