How to save a variable, using AJAX, a database mySQL using Coldfusion?
I have a jquery script that takes a background color of an image using AJAX. I would like to save the variable, var rgba = e.rgba () on a MySQL database. The person who created the script says to use: $.post("color.php",{rgba:reba});) to save a database with AJAX. How to save the var rgba using coldfusion to do CF?
The script:
< script >
;(Function($){
$. fn.canvasify = function (f) {/ / faster than dynamically converting one pixel at a time}
return this.map (function () {}
If {(this.nodeName=="IMG)"}
var canvas = $("< canvas >')
This.SRC = this.src / / IE fix
$(this) .one ('load', function () {}
Canvas.Attr ({width: this.width,:this.height}) height})
Canvas [0]. GetContext ('2d'). DrawImage(This,0,0,this.) Width, this. Height)
$(this) .replaceWith (canvas)
})
return the canvas [0]
} else {}
return this
}
})
}
function Rgba (rgba) {}
This.RGBA = rgba
this.toString = function() {return "rgba (" + Array.prototype.join.call (this.rgba, ',') + ")"}
}
$. {Event.prototype.RGBA = Function ()}
var x = this.offsetX | (this.pageX - $(this.target) .offset () .left),.
this.offsetY = y | (this.pageY - $(this.target) .offset () .top).
nodeName = this.target.nodeName
If (nodeName = "CANVAS")
return new Rgba (this.target.getContext('2d').getImageData(x,y,1,1) .data)
ElseIf (nodeName = 'IMG') {}
var canvas = document.createElement ("canvas")
Canvas.Width = 1
Canvas.Height = 1
canvas.getContext('2d').drawImage (this.target, x, y, 1, 1, 0, 0, 1, 1)
return new Rgba (canvas.getContext('2d').getImageData (0,0,1,1) .data)
} otherwise return null
}
(}) (jQuery)
{$(function()}
$("figure").append ("< class p =" rgba">" ")
$('img').canvasify ravishing (demo))
$('img').click (demo)
function {persons
var rgba = e.rgba (),
digit = $(this) .parent)
Figure.CSS ('background-color', RGBA). Find ("p"). Text (RGBA)
}
});
< /script >
< style >
{p.RGBA}
background: white;
color: black;
border: 1px solid red;
min-height: 20px;
}
< / style >
Here's some pseudocode
AJAX
...
$data = {RGBA: $rgba, var1 = $var1, var2 = $var2, etc.};
...
var ajaxResponse = $.ajax({)
type: 'POST',
URL: '.. '. /.. /dir/settings.CFC? Method = saveBGColor,
contentType: "application/json; charset = utf-8 ",
data: JSON.stringify ($data).
etc.
});
Settings.CFC

How to save an Image on a Sql database without losing the Vision Info?
Hello
is it possible to save an image with the info of the vision in a Sql Server 2005 database? I tried the method of ImagetoArray and saved table in a varbinary field, but the info of the vision is lost.
Kumi-
You can do something like this (assuming that you already have the Image):
imageString of object = null;
CWIMAQFlattenOptions options = new CWIMAQFlattenOptions();
Options. Type = CWIMAQFlattenTypes.cwimaqFlattenTypeImageAndVisionInfo;
axCWIMAQVision1.FlattenImage (Image, options, imageString Ref);
Byte [] imageData = imageString (byte []);and then imageData will hold the content of the image. You can pass this to CWIMAQVision.UnflattenImage () to restore the data.

My MacBook Pro doesn't start then you want to erase and reinstall iOS. Before doing this I want to back up all my files. If I connect to imac via FireWire I can view all the files, but how can I save it it?
If your MacBook will start in target disk Mode, follow the instructions on how to set up and use...
Share files between two computers with target - Apple Support disk mode
But you do not want to share files, just to save them. You can make a "clone", using disk utility. For cloning utility purposes use a program likeSuperDuper! or double clone.

Somehow, I downloaded and installed Adobe alleged DC update for the existing acrobat Reader installed on my laptop.
DC app has been a disaster for me in terms of generation of convoluted navigation and extra work.
In addition, I do NOT trust or want an application based on a cloud because of the deep and hard-learned risk, privacy and security, as well as the occasional loss of connectivity online and access, what urgent needs can get GROUND in terms of use of such an external cloud-based application.
Issues related to the:
[1] how to save a PDF downloaded and open directly on my laptop, a report file to save the file in the cloud and then copying it in the folder of the laptop? This process in several steps inside the DC is a frustrating PITA, as Adobe Acrobat Reader has been sufficient for my needs.
can [2] Alternatively, I remove CD and install the latest version of Adobe Acrobat Reader, which is thin and easier to use for my needs and much, much more secure?
Thank you very much in advance for the help and deliberate in a timely & the readers attention. Today is Tuesday, November 3, 2015.

Hi stephenf95557665,
(1) you can simply save the file on your computer as allows you to save in the older version of the player, it is not necessary to register I your cloud of document.
If you save the file to the document cloud, you will be able to access any system from anywhere.
(2) If you still think earlier version users need, then they can probably uninstall the last being & reinstall the old version using this link http://get.adobe.com/reader/enterprise/
Kind regards

Look at the script on the FPDF under 'Scripts' site below
2002-12-25 Olivier Table with MySQL First you must download the file of fpdf.php since the site under the downloads"" section.
Copy the first block of coding 'Source' from the example script and save it under-
mysql_table.php
Next copy the second code block and insert it into a new document in DW, modify the code as shown in red below and save it as pdf_output.php - make sure that the paths to include the mysql_table.php and the (fpdf.php file which is included in the mysql_table.php file) are correct.
Also change the connection to your database in the code below.
require('mysql_table.php');
class PDF extends PDF_MySQL_Table
{
function Header()
{
//Title
$this->SetFont('Arial','',18);
$this->Cell(0,6,'Database Data',0,1,'C');
$this->Ln(10);
//Ensure table header is output
parent::Header();
}
}//Connect to database
mysql_connect('server','login','password');
mysql_select_db('db');$pdf=new PDF();
$pdf->AddPage();
//First table: put all columns automatically
$pdf->Table('SELECT No, Calon, ID, Jurusan, Undi FROM candidates order by Undi desc');
$pdf->Output();
?>If you have set up properly and navigate to - pdf_output.php - it should produce a pdf of the extracted data in your database.
A draw back is it uses mysql and mysqli - which is not an immediate problem, as long as you do not mix mysql and mysqli - as this is a stand alone page, it should be ok. (and of course as long as your server still supports the mysql extension)
