When i tried testing only with data object it works fine Any help would be great.

  • Problem Fetching JSON Result with jQuery in Firefox and Chrome (IE8 Works)

    - by senfo
    I'm attempting to parse JSON using jQuery and I'm running into issues. Using the code below, the data keeps coming back null: <!DOCTYPE html> <html> <head> <title>JSON Test</title> </head> <body> <div id="msg"></div> <script src="http://code.jquery.com/jquery-latest.js"></script> <script> $.ajax({ url: 'http://datawarehouse.hrsa.gov/ReleaseTest/HGDWDataWebService/HGDWDataService.aspx?service=HC&zip=20002&radius=10&filter=8357&format=JSON', type: 'GET', dataType: 'json', success: function(data) { $('#msg').html(data[0].title); // Always null in Firefox/Chrome. Works in IE8. }, error: function(data) { alert(data); } }); </script> </body> </html> The JSON results look like the following: {"title":"HEALTHPOINT TYEE CAMPUS","link":"http://www.healthpointchc.org","id":"tag:datawarehouse.hrsa.gov,2010-04-29:/8357","org":"HEALTHPOINT TYEE CAMPUS","address":{"street-address":"4424 S. 188TH St.","locality":"Seatac","region":"Washington","postal-code":"98188-5028"},"tel":"206-444-7746","category":"Service Delivery Site","location":"47.4344818181818 -122.277672727273","update":"2010-04-28T00:00:00-05:00"} If I replace my URL with the Flickr API URL (http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?), I get back a valid JSON result that I am able to make use of. I have successfully validated my JSON at JSONLint, so I've run out of ideas as to what I might be doing wrong. Any thoughts? Update: I had the client switch the content type to application/json. Unfortunately, I'm still experiencing the exact same problem. I also updated my HTML and included the live URL I've been working with. Update 2: I just gave this a try in IE8 and it works fine. For some reason, it doesn't work in either Firefox 3.6.3 or Chrome 4.1.249.1064 (45376). I did notice a mistake with the data being returned (the developer is returning a collection of data, even for queries that will always return a single record), but it still baffles me why it doesn't work in other browsers. It might be important to note that I am working from an HTML file on my local file system. I thought it might be a XSS issue, but that doesn't explain why Flickr works.

  • Creating subtree from tree which is represented in xml - python

    - by Jay
    Hi I have an XML (in the form of tree), I require to create sub-tree out of it. For ex: <a> <b> <c>Hello</c> <d> <e>Hi</e> </a> Subtree would be <root> <a> <b> <c>Hello</c> </b> </a> <a> <d> <e>Hi</e> </d> </a> </root> What is the best XML library in python to do it? Any algorithm that already does this would also be helpful. Note: the XML doc won't be that big, it will easily fit in memory.

  • what is wrong: "value Parsers is not a member of package scala.util.parsing.combinator"?

    - by Nick Fortescue
    I've got the above odd error message that I don't understand "value Parsers is not a member of package scala.util.parsing.combinator". I'm trying to learn Parser combinators by writing a C parser step by step. I started at token, so I have the classes: import util.parsing.combinator.JavaTokenParsers object CeeParser extends JavaTokenParsers { def token: Parser[CeeExpr] = ident } abstract class CeeExpr case class Token(name: String) extends CeeExpr This is as simple as I could make it. The code below works fine, but if I uncomment the commented line I get the error message given above: object Play { def main(args: Array[String]) { //val parser: _root_.scala.util.parsing.combinator.Parsers.Parser[CeeExpr] CeeParser.token val x = CeeParser.token print(x) } } In case it is a problem with my setup, I'm using scala 2.7.6 via the scala-plugin for intellij. Can anyone shed any light on this? The message is wrong, Parsers is a member of scala.util.parsing.combinator.

  • javascript to select text from web page

    - by phil swenson
    I'm trying to write a bookmarklet that grabs any selected text on a web page and sends it to my website. It should (hopefully) work in Chrome, FFX, Safari, and IE. I did a search and found a function, but it doesn't appear to work. Here is the code: <html> <body> <div onClick=getSelText()>Click</div> <div>please select me</div> </body> <script language=javascript> function getSelText(){ var txt = 'nothing'; if (window.getSelection){ txt = "1" + window.getSelection(); } else if (document.getSelection) { txt = "2" + document.getSelection(); } else if (document.selection) { txt = "3" + document.selection.createRange().text; } else return; alert("selected text = " + txt); } </script> </html> when I select the text in the div "please select me" and hit the click div, I just get "selected text = 1" thanks

  • String Manipulation in C

    - by baris_a
    Hi guys, I am helping my nephew for his C lab homework, it is a string manipulation assignment and applying Wang's algorithm. Here is the BNF representation for the input. <sequent> ::= <lhs> # <rhs> <lhs> ::= <formulalist>| e <rhs> ::= <formulalist>| e <formulalist> ::= <formula>|<formula> , <formulalist> <formula> ::= <letter>| - <formula>| (<formula><in?xop><formula>) <in?xop> ::= & | | | > <letter> ::= A | B | ... | Z What is the best practice to handle and parse this kind of input in C? How can I parse this structure without using struct? Thanks in advance.

  • Wrap words in tags, keep markup

    - by spacevillain
    For example I have a string with markup (from html node): hello, this is dog "h<em>e<strong>llo, thi</strong>s i</em><strong>s d</strong>og" What is the most correct way to find some words in it (let's say "hello" and "dog"), wrap them in a span (make a highlight) and save all the markup? Desired output is something like this (notice properly closed tags) <span class="highlight">h<em>e<strong>llo</strong></em></span><strong>,</strong> <em><strong>thi</strong>s<em> i</em><strong>s <span class="highlight"><strong>d</strong>og</span> Looks the same as it should: hello, this is dog

  • Convert an XML object back into a string in ColdFusion

    - by jpmyob
    In ColdFusion, I can parse a string of XML formatted data into an XML Object using xmlParse(). How can I convert it back into a string? When I tried using toString() it throws an error that "it can't convert complex object to simple objects....", which is ironic because that's what it's supposed to do. I need to use XMLTransform() which requires the first argument to be an xml string. But I also need to use xmlSearch() to get a node to pass into my transform, and xmlSearch returns an xmlObject. So now I need to put that object back into xml string format to pass into xmlTransform.

  • PyParsing: Is this correct use of setParseAction()?

    - by Rosarch
    I have strings like this: "MSE 2110, 3030, 4102" I would like to output: [("MSE", 2110), ("MSE", 3030), ("MSE", 4102)] This is my way of going about it, although I haven't quite gotten it yet: def makeCourseList(str, location, tokens): print "before: %s" % tokens for index, course_number in enumerate(tokens[1:]): tokens[index + 1] = (tokens[0][0], course_number) print "after: %s" % tokens course = Group(DEPT_CODE + COURSE_NUMBER) # .setResultsName("Course") course_data = (course + ZeroOrMore(Suppress(',') + COURSE_NUMBER)).setParseAction(makeCourseList) This outputs: >>> course.parseString("CS 2110") ([(['CS', 2110], {})], {}) >>> course_data.parseString("CS 2110, 4301, 2123, 1110") before: [['CS', 2110], 4301, 2123, 1110] after: [['CS', 2110], ('CS', 4301), ('CS', 2123), ('CS', 1110)] ([(['CS', 2110], {}), ('CS', 4301), ('CS', 2123), ('CS', 1110)], {}) Is this the right way to do it, or am I totally off? Also, the output of isn't quite correct - I want course_data to emit a list of course symbols that are in the same format as each other. Right now, the first course is different from the others. (It has a {}, whereas the others don't.)

  • Reduce white space between lines of text

    - by user654466
    I am creating a webpage (first time) and i'm following as much of the CSS rules and tags as I can. However, I ran into a problem with white space. I've underlined the first line of text but now the second line seems to have drifted below. Is there a way to make it a bit more snug, i'd like the second line of text to be just below the above line. body,td,th { color: #000000; } body { margin: 0; padding: 0; padding-top: 6px; text-align: center; background-color: #FFFFFF; } #centered { width: 800px; /* set to desired width in px or percent */ text-align: left; /* optionally you could use "justified" */ border: 0px; /* Changing this value will add lines around the centered area */ padding: 0; margin: 0 auto; } .style3 { font-size: 32pt; color: #666666; margin-left: 0px; border-bottom: 3px double; } .style5 { margin-left: 390px; font-size: 32pt; color: #CCCCCC; } --> </style></head> <div id="centered"> <body> <p class="style3">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FIRST LINE OF TEXT</p> <p class="style5">INDENTED SECOND LINE</p> </body> </div> </body> </html>

  • FileHelpers cannot map converted field into destination array

    - by jaffa
    I have the following record (reduced for brevity): [DelimitedRecord(",")] [IgnoreFirst] [IgnoreEmptyLines()] public class ImportRecord { [FieldQuoted] [FieldTrim(TrimMode.Both)] public string FirstName; [FieldQuoted] [FieldTrim(TrimMode.Both)] public string LastName; [FieldQuoted] [FieldTrim(TrimMode.Both)] [FieldOptional] [FieldConverter(typeof(TestPropertyConverter))] public int[] TestProperty; } Converter code: public class TestPropertyConverter : ConverterBase { public override object StringToField(string from) { var ret = from.Split('|').Select(x => Convert.ToInt32(x)).ToArray(); return ret; } } So an example record could be: John, Smith, 1|2|3|4 It would expect the values 1,2,3,4 to expand and fill the TestProperty array. However, I'm getting the following exception: At least one element in the source array could not be cast down to the destination array type. I've tried to debug into the code and it seems to blow-up in the ExtractFieldValue() function inside FieldBase.cs where it tries to return out of the function. The following line seems to be the culprit: res.ToArray(ArrayType); It seems to expect the 'res' variable to be the destination type array, but it contains 1 element of the array itself. Can anyone suggest if I'm doing this wrong or a possible fix?

  • In Ruby Compare 2 lines in a log file which BOTH contain the SAME "WORD" but ONLY print out the line

    - by kamal
    here are sample lines Apr 9 11:53:26 skip [2244]: [2244] ab-cd-ef:cc [INFO] A recoverable error has occurred some other log lines .. .... Apr 9 12:53:26 skip [2244]: [2244] ab-cd-ef:cc [INFO] A recoverable error has occurred now the LATEST line would have to be one with the latest Date String, and THAT is the one that needs to be printed, plus the NEXT time the parser runs on the log file, somehow the previous LATEST line has to be compared with the Existing latest one, and it CAN e the case, that NOTHING Changed and the OLD line is STILL the latest one, OR there is a NEW line, but ONLY the NEW log line should be printed and NOT if there is NO NEW log Entry.

  • how to detect escape characters in a string

    - by mix
    Given a string named line whose raw version has this value: \rRAWSTRING how can I detect if it has the escape character \r? What I've tried is: if repr(line).startswith('\r'): blah... but it doesn't catch it. I also tried find, such as: if repr(line).find('\r') != -1: blah doesn't work either. What am I missing? thx!

  • Identifying individual values in a text box using Flash

    - by Jamash1989
    I want to identify specific strings in a text box from user input to add to a score variable, like so - if (userWords.text == firstWord) { score = score + 1; } The example given adds 1 to the score, but if a user adds a space then a second word the text box views it as a whole and not individual words, resulting in no values added to the score variable. The problem lies with the whole text box being viewed as one entire string. Instead, I want to split it up so word1 will add 1 to the score, word2 will add 1 to the score, etc. I am ultra confused with this problem, so thank you to anyone that may help.

  • What is the easiest way to loop through a folder of files in C#?

    - by badpanda
    I am new to C# and am trying to write a program that navigates the local file system using a config file containing relevant filepaths. My question is this: What are the best practices to use when performing file I/O (this will be from the desktop app to a server and back) and file system navigation in C#? I know how to google, and I have found several solutions, but I would like to know which of the various functions is most robust and flexible. As well, if anyone has any tips regarding exception handling for C# file I/O that would also be very helpful. Thanks!!! badPanda

  • How to use JQuery to truncate the contents of option tags?

    - by George
    Hello! Please take a look here: http://www.binarymark.com/Products/FLVDownloader/order.aspx What I am trying to do is to get rid of the prices inside the option tag. On that page you can see a drop-down box under Order Information, Product. I want to remove the prices from all the options that contain them in that box, so get rid of " - $75.98" for example. I am not used to JQuery, but I realize it would be possible - just not sure how to do it, so your help would be greatly appreciated. Thanks. George

  • Parser that accepts Scala Identifiers?

    - by Mirko Stocker
    I was wondering whether the standard Scala parser combinators contain a parser that accepts the same identifiers that the Scala language itself also accepts (as specified in the Scala Language Specification, Section 1.1). The StdTokenParsers trait has an ident parser, but it rejects identifiers like empty_?. (If there is indeed no such parser, I could also just instantiate the Scala parser itself, but that wouldn't be as lightweight anymore.)

  • Python/YACC Lexer: Token priority?

    - by Rosarch
    I'm trying to use reserved words in my grammar: reserved = { 'if' : 'IF', 'then' : 'THEN', 'else' : 'ELSE', 'while' : 'WHILE', } tokens = [ 'DEPT_CODE', 'COURSE_NUMBER', 'OR_CONJ', 'ID', ] + list(reserved.values()) t_DEPT_CODE = r'[A-Z]{2,}' t_COURSE_NUMBER = r'[0-9]{4}' t_OR_CONJ = r'or' t_ignore = ' \t' def t_ID(t): r'[a-zA-Z_][a-zA-Z_0-9]*' if t.value in reserved.values(): t.type = reserved[t.value] return t return None However, the t_ID rule somehow swallows up DEPT_CODE and OR_CONJ. How can I get around this? I'd like those two to take higher precedence than the reserved words.

  • How can I parse through a texutre in DirectX? (IDirect3DTexture9*)

    - by meds
    I've been trying to figure out how to parse textures in directx for two reasons: to write my own texture format and to manipulate data in existing IDirect3DTexture9 type textures. I've been looking at the IDirect3DTexture9::LockRect() function but I'm unsure how it works, are the void* pBits I get out of it in D3DLOCKED_RECT the data in the texture? Does that mean I can read it in by converting it to D3DXCOLOR or something? Really not sure where to go, any help would be appreciated!
