  • Using jQuery, how do I way attach a string array as a http parameter to a http request?

    - by predhme
    I have a spring controller with a request mapping as follows @RequestMapping("/downloadSelected") public void downloadSelected(@RequestParam String[] ids) { // retrieve the file and write it to the http response outputstream } I have an html table of objects which for every row has a checkbox with the id of the object as the value. When they submit, I have a jQuery callback to serialize all ids. I want to stick those ids into an http request parameter called, "ids" so that I can grab them easily. I figured I could do the following var ids = $("#downloadall").serializeArray(); Then I would need to take each of the ids and add them to a request param called ids. But is there a "standard" way to do this? Like using jQuery?

  • How do I use Ajax and Jquery to get an array from PHP and post it?

    - by Jared
    Hello, I am using a separate PHP file as a configuration file for everything else on a basic ecommerce site. $product1["short"] = "product one"; $product1["menuimgslideshowsrc"] = "image/product1.jpg"; When I hover over a button, I want to get $product1["menuimgslideshowsrc"] and swap it out with an IMG SRC. I can do the swapping no problem, I need to know how to get the information stored in $product1["menuimgslideshowsrc"]. I assume I would use Ajax, but I am open to other ideas. Thanks in advance.

  • Creating a function to grab data from an Oracle database (array by ID)

    - by Nick
    I'm trying to create a function that will simply allow me to pass an SQL statement into it, and it will generate an array based on a unique ID I pass it: function oracleGetGata($query, $id="id") { global $conn; $sql = OCI_Parse($conn, $query); OCI_Execute($sql); OCI_Fetch_All($sql, $results, null, null, OCI_FETCHSTATEMENT_BY_ROW); return $results; }   For example I'd like this query $array = oracleGetData('select * from table') to return something like: [1] => Array ( [Title] => Title 1 [Description] => Description 1 ) [2] => Array ( [Title] => Title 2 [Description] => Description 2 ) [3] => Array ( [Title] => Title 3 [Description] => Description 3 )   Rather than what it's returning at the moment: [0] => Array ( [ID] => 3 [TITLE] => Title 3 [DESCRIPTION] => Description 3 ) [1] => Array ( [ID] => 1 [TITLE] => Title 1 [DESCRIPTION] => Description 1 ) [2] => Array ( [ID] => 2 [TITLE] => Title 2 [DESCRIPTION] => Description 2 )   I'd really appreciate any help with this, as the function would save me lots of time! Thank you.

  • Dimensions of a collection, and how to traverse it in an efficient, elegant manner

    - by Bruce Ferguson
    I'm trying to find an elegant way to deal with multi-dimensional collections in Scala. My understanding is that I can have up to a 5 dimensional collection using tabulate, such as in the case of the following 2-Dimensional array: val test = Array.tabulate[Double](row,col)(_+_) and that I can access the elements of the array using for(i<-0 until row) { for(j<-0 until col) { test(i)(j) = 0.0 } } If I don't know a priori what I'm going to be handling, what might be a succinct way of determining the structure of the collection, and spanning it, without doing something like: case(Array(x)) => for(i<-1 until dim1) { test(i) = 0.0 } case(Array(x,y)) => for(i<-1 until dim1) { for(j<-1 until dim2) { test(i)(j) = 0.0 } } case(Array(x,y,z)) => ... The dimensional values n1, n2, n3, etc... are private, right? Also, would one use the same trick of unwrapping a 2-D array into a 1-D vector when dealing with n-Dimensional objects if I want a single case to handle the traversal? Thanks in advance Bruce

  • How to move positions within an array?

    - by Jade Mulholland
    A program that simply moves array elements. Two variables: userInputVariable and blankSpaceVariable. I have a 2D array named table. Defined as table[userInputVariable + 1][6] I am printing out this array in a table format, and the far left column is numbered by whatever number the user entered at the beginning of the program. I then ask the user where they would like to enter a blank space within the array. This blank space acts like a divider for all the other information in the array. For example, if the user enters 10 at the start for the userInputVariable, and then enters 5 for the blank space. Once printed, the numbers should go like this: 1, 2, 3, 4, --, 5, 6, 7, 8, 9, 10. My plan has been to create a for loop and try to move all the numbers in the array back a position starting from the blank space variable. What I currently have, but does not work: for (int i = blankSpaceVariable; i < table.length - 1; i++) { table[i] = table[i + 1]; } table[blankSpaceVariable] = "--"; With my current code, the numbers go like this: 1, 2, 3, 4, 6, 7, 8, 9, 10 Tried completing this a few different ways also, but the other info within my 2D array didn't move with the numbers. So I thought that this approach can hopefully move all the info within my 2D array down, and make way for a blank section. All help is greatly appreciated!

  • How do I iterate over an Array field reflectively?

  • How can I start with <a href=" and have an array element here then end with </a>?

    - by Noor
    The thing im trying to do right now is pulling in multiple links from a textarea, We can pretend that a user inputs c:\pics\img01.jpg and in the next row he'll have the next imglink. I want to pull those links, I allready have the code for that: var entered = $('#filedir').val(); var lines = entered.split(/\r\n/); var opttext = ""; for(var i=0;i<lines.length;i++) { opttext += '< img src="' + lines[i] + '">< /img>'; } ? the problem is in the output which is: < img src="file:///C:/pics/img01.jpgc:/pics/img02.jpg">< /img> There should be two < img> elements.. Where am I going wrong? I've been at it for a bit over 2 hours now..

  • Selecting value from array results

    - by Swodahs
    Being new to learning PHP I am having trouble with understanding how to select/echo/extract a value from array result a API script returns. Using the standard: echo "<pre>"; print_r($ups_rates->rates); echo "</pre>"; The results returned look like this: Array ( [0] => Array ( [code] => 03 [cost] => 19.58 [desc] => UPS Ground ) [1] => Array ( [code] => 12 [cost] => 41.69 [desc] => UPS 3 Day Select ) [2] => Array ( [code] => 02 [cost] => 59.90 [desc] => UPS 2nd Day Air ) ) If I am only needing to work with the values of the first array result: Code 3, 19.58, UPS Ground --- what is the correct way to echo one or more of those values? I thought: $test = $ups_rates[0][cost]; echo $test; This is obviously wrong and my lack of understanding the array results isn't improving, can someone please show me how I would echo an individual value of the returned array and/or assign it to a variable to echo the normal way?

  • Java - Tile engine changing number in array not changing texture

    - by Corey
    I draw my map from a txt file. Would I have to write to the text file to notice the changes I made? Right now it changes the number in the array but the tile texture doesn't change.

  • Meta package / quick reference for command line string manipulation tools?

    - by Dylan McCall
    The latest version of the Scribes text editor lets us select some text, hit Alt+X, and then run an arbitrary command. For example, I can run the sort command and the selected text is replaced appropriately. This is quite useful but I am also not very well-versed in awk and the like. Is there something I can grab that will provide more of these commands like sort? Maybe a package with a whole bunch of handy, task-specific string manipulation commands?

  • How to properly override Drupal imagecache presets

    Say I need to override defaul presets, provided by Ubercart module.

Nothing works now. Where is the mistake?

  • NullReferenceException when accessing variables in a 2D array in Unity

  • RGB values from image into a one dimension array in c#

    I was wondering if there is a was a way to read rgb values from an image into a one dimensional array in C#. If it doesnt make sense, in java I would do something like this. int[] pixels; BufferedImage image = getClass().getResourceAsStream("asdfghjkl.png"); int w = image.getWidth(); int h = image.getHeight(); pixels = new int[w * h]; image.getRGB(0, 0, w, h, pixels, 0, w) ; So any help would be great, or if you can point me in the right direction, that'd be great

  • Handy Javascript array Extensions &ndash; distinct()

    The following code adds a method to javascript arrays that returns a distinct list of values. Array.prototype.distinct = function() { var derivedArray = []; for (var i = 0; i < this.length; i += 1) { if (!derivedArray.contains(this[i])) { derivedArray.push(this[i]) } } return derivedArray; }; and to demonstrate: alert([1,1,1,2,2,22,3,4,5,6,7,5,4].distinct().join(',')); This produces 1,2,22,3,4,5,6,7

  • Unable to Mount Seagate Array from Iomega

    - by GE Cardiff
    I am new to Ubuntu so please be kind! My (Windows based) Iomega Storcentre ix2-200 stopped working, with all my business data upon it. Iomega helpfully told me that I should get Fedora, remove the Seagate hard drives and recover the information by connecting via a USB / SATA cable. First I could not get Fedora to load (due to it needing an Internet connection before loading complete) so I got Ubuntu - much easier to load. Software seems fine, and in "Computer" there is an "Array" icon - this is clearly the Seagate hard drive I have connected. It will not, however, Mount. "Unable to mount location, can't mount file". Any help gratefully received! As a slight aside, I can't seem to find "terminal" in this version of Ubuntu?

  • Determining Whether a String Is Contained Within a String Array (Case Insensitive)

    About once every couple of months I need to write a bit of code that does one thing if a particular string is found within an array of strings and something else if it is not ignoring differences in case. For whatever reason, I never seem to remember the code snippet to accomplish this, so after spending 10 minutes of research today I thought I'd write it down here in an effort to help commit it to memory or, at the very least, serve as a quick place to find the answer when the need arises again.So without further adieu, here it is:Visual Basic Version:If stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase) Then ... Else ... End IfC# Version:if (stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase)) ... else ...Without the StringComparer.OrdinalIgnoreCase the search will be case-sensitive.

  • Removing mdadm array and converting to regular disks while preserving data

    - by Jeffrey Kevin Pry
    I have a 6 disk (2TB each) mdadm RAID 5 volume created in Ubuntu 12.04 Server. However, I'm moving to a different solution and want to "unraid" my disks but keep the data. Only 50% is in use. From what I can surmise I basically have to do this recursively for each physical disk. Fail the disk Format the failed disk Move a portion of files to the new disk. Reshape the array Shrink the logical volume md0 This seems like a very time consuming process. Is there an easier way to do this (automatically perhaps) without buying new disks to temporarily hold the data? I am also aware that during this processing my RAID volume will be degraded and vulnerable the entire time. I am not too concerned about this and will be using battery backup and moving the most important files off first. Thank you for your help!

  • Comparison between a value with static type Array and a possibly unrelated type Class

    I got this error: Comparison between a value with static type Array and a possibly unrelated type Class. After i modify the class to many classes (before that, everything is on 1 class (all of the functions)), but after i move everything to many classes (all the functions is not on 1 class), that error appear. How to solve this? I am using AS3 and as3isolib Library.

  • Whole map design vs. tiles array design

    - by Mikalichov
    I am working on a 2D RPG, which will feature the usual dungeon/town maps (pre-generated). I am using tiles, that I will then combine to make the maps. My original plan was to assemble the tiles using Photoshop, or some other graphic program, in order to have one bigger picture that I could then use as a map. However, I have read on several places people talking about how they used arrays to build their map in the engine (so you give an array of x tiles to your engine, and it assemble them as a map). I can understand how it's done, but it seems a lot more complicated to implement, and I can't see obvious avantages. What is the most common method, and what are advantages/disadvantages of each?

  • Regex: replace inner string

    - by AllenG
    I'm working with X12 EDI Files (Specifialy 835s for those of you in Health Care), and I have a particular vendor who's using a non-HIPAA compliant version (3090, I think). The problem is that in a particular segment (PLB- again, for those who care) they're sending a code which is no longer supported by the HIPAA Standard. I need to locate the specific code, and update it with a corrected code. I think a Regex would be best for this, but I'm still very new to Regex, and I'm not sure where to begin. My current methodology is to turn the file into an array of strings, find the array that starts with "PLB", break that into an array of strings, find the code, and change it. As you can guess, that's very verbose code for something which should be (I'd think) fairly simple. Here's a sample of what I'm looking for: ~PLB|1902841224|20100228|49KC15X078001104|.08~ And here's what I want to change it to: ~PLB|1902841224|20100228|CSKC15X078001104|.08~ Any suggestions?

  • How to access pixels of an NSBitmapImageRep?

    - by Paperflyer
    I have an NSBitmapImageRep that is created like this: NSBitmapImageRep *imageRep = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:waveformSize.width pixelsHigh:waveformSize.height bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:YES colorSpaceName:NSCalibratedRGBColorSpace bytesPerRow:0 bitsPerPixel:0]; Now I want to access the pixel data so I get a pointer to the pixel planes using unsigned char *bitmapData; [imageRep getBitmapDataPlanes:&bitmapData]; According to the Documentation this returns a C array of five character pointers. But how can it do that? since the type of the argument is unsigned char **, it can only return an array of chars, but not an array of char pointers. So, this leaves me wondering how to access the individual pixels. Do you have an idea how to do that? (I know there is the method – setColor:atX:y:, but it seems to be pretty slow if invoked for every single pixel of a big bitmap.)
