AJAX :: Parsing A String Returned With Technology?
Dec 6, 2009
Through an AJAX implementation, I am receiving a SQL Query result that has:An object's attribute delimited by a comma.An entire object (database row) delimited by a colon.This is an example response to make it more clear for you.
What I am trying to achieve is placing all of this data into an array. I've set up a little test bed to try and get this to work; this is all I have so far:
var testString = "1,Jeremy,130,80;2,Lauren,370,300;3,Jeancarlos,200,200;4,Luke,330,70;5,Bloom,392,108";
var testArray = new Array();
testArray = testString.split(";");[code]....
get a multi-dimensional array that has information for each person. Example:
FinalArray[0][0] = 1
FinalArray[0][1] = Jeremy
FinalArray[0][2] = 130
I am trying out $.ajax instead of getJSON for debugging purposes. Because getJSON did not report an error in IE (6,7 or 8) and I am trying to figure out why a jQuery plug-in is not painting my returned images to the screen in IE but is in other browsers. So I tried this. Interestingly enough, it hits the error event in IE but not firefox, safari and the rest and I don't know why (this code works great and renders my data just fine in FireFox and the rest). I know my returned json is valid:
I don't know what else to do to troubleshoot why IE is having so much trouble with the returned JSON or just executing the function(data) using either getJSON OR this. I have set the headers not the cache also in the response. IE refuses to enter my function(data) on the response.
Same result. Firefox and the rest had no issue. IE still exited the $.ajax and my error method kicked in. No rhyme or reason whatsoever and I tried the IE Dev tools... nothing. About the only thing I get is this: Line: 163 Error: System error: -1072896658.Line 163 which is simply the line: function() { alert("An error has occurred. try again."); This has got to be the most f*d up situation I've been in and I need to get this working! I just cannot understand why IE can't parse a getJSON or $.ajax response, that is impossible or else there would be a huge meltdown with jQuery.
We have a Java and JSP environment and are looking at options for the client, such as using Ajax. It would be especially interesting to get comparisons (e.g., pros and cons) with applets or other approaches.
I have a form that I am using to generate an email with several user selected fields being part of it. As part of this form, I have a select box which allows the user to select which email addresses it should be sent to. The box works great except that the CGI script I'm sending the values to can only parse a single line for each field in the form. The issue comes into play when someone selects more than one value in the select box, the output of the select box seems to separate each value on a separate line using a line feed (or carriage return, I can't tell). The format that the CGI script needs is for a single line with each of these values separated by a comma. I'm confident that a javascript can do this fairly easily, but unfortunately, I am not very well versed in javascript. I've found a few code snippets on the web that I've mangled together, but since I don't really know what I'm doing, it isn't working out so good. I've included what I have in the form right now below (note that I've removed all of the other form data but the select box code to save space). Code:
I am doing a few tests with javascript and oop. but one failed so i falled back to the way i usually do this but it still isnt working properly. i am using $.post() but instead of returning whatever is echoed in the php file like it does with all my other scripts it returns the content of the file:
Isnt returned in var data but the whole file is returned as a string.
I am working on the HTML Code in which i write the 2 pages for SMS Sender & SMS Receiver in that from the SMS Sender when the user sends the SMS it lands on server URL as:[URL]The query is regarding the how to parse the content from the incoming Messgae & the content are shown on the Receiver side. by parsing the Sender Number & the message content from the URL & Receiver side URL is:[URL]how to write the Function for parsing the URL & seperating the SMS Sender & Message content
I wrote a .repeat(n) function for strings which seemed to work fine:
String.prototype.repeat = function(n) { // repeats the string n times if (n<1) return ""; if (n<2) return this; for (var aStr = [this];--n>0;) aStr.push(aStr[0]); return aStr.join(""); }
Only I was a little surprised to get "object" (instead of "string") when I tried: alert (typeof ("x".repeat(1)));
I fixed this by modifying ... if (n<2) return this+"";
I have to do something that looks an easy task, but I can't do it.I have a page with a div and an id= "livetimings" assigned to it, I want to show a table inside that div and update it every 20 seconds.I have a php script which prints the table and it works, I've tried that script by itself, now I'm trying to call it through an AJAX call in this way [code]inside the <body> tag I've put a setInterval() which starts the getTempi() every 20 seconds and it also works.The not working part is that nothing appears inside the div.I've put some alerts inside the JS code all of them before the req.open pop up, then nothing, so I think the problem is there, but I don't get it.script.php is in the same folder of the html page.The php script has an echo at the end which prints the html code for the table.
I have a string array in a class file that contains 5 values, which I need to display on the jsp page. but when I send it to the javascript it prints [Ljava.lang.String;@104f8b8 .what do i do about it. I am a new to javascript. Is there a way to get my array data from the response object.
I am really stuck in parsing a JSON string and take it's values. I got the json string as

How to Parse this and take the Results for further processing in javascript.... I am waiting to hear from you Soon..I am using jQuery for the purpose...
LISPPA (List Processing based on the Polymorphic Arrays) technology is a way to process dynamic data structures (lists, trees and more) without using pointers. LISPPA uses polymorphic arrays as a base of the data representation.
A very important example of polymorphic arrays is the variant arrays in such languages as Visual Basic, Object Pascal (Delphi) and other. The current implementation of LISPPA has been created on the base of extension of the ariant type. All languages of the paxScript scripting engine: paxPascal, paxBasic, paxC, paxJavaScript support LISPPA. Code:
Hi, I'm fairly new to AJAX, but I've been able to retrieve HTML and plain-text documents without any trouble. However, I haven't figured out how to retrieve it in XML format. Basically, here's the script that's supposed to retrieve and parse the data when you pass it the url of the page generating the XML data:
I'm trying to use it to load in an XML file and output some data. I followed a tutorial on it but my XML file isn't loading.[code]Now my thinking is that when the document loads, it alerts me that the jQuery is running, and it does this. I had hoped that after closing that alert, another one would show saying that the XML file has loaded - This would ensure that the function 'parseXML' has been called, but it does not return an alert or populate my#xml_addressbook div.My index page is at the root, and both my XML file and the javascript file are in a folder, as shown below.[code]
I'm building an application with a c#.net server and a good bit of jquery on the front end. I'm having trouble getting/parsing data from c#. In the C#, I am doing a db call to pull the information for all users, and putting it into xml format:
string xml = "<?xml version='1.0' encoding='utf-8' ?>"; xml += "<Users>"; while (res.Read()) {
[Code].....
When I run the application, I'm getting the 'in AjaxSucceeded [object XMLDocument]' alert, but I cannot get inside of the 'each' loop.
I have a <div> tag that contains a table of results returned using AJAX. I have an onmouseover on the div so that when the user is viewing the results the div stays visible. An onmouseout is also declared so that when the user goes off of the div, it will disappear after a few seconds. When the user clicks on an entry I perform some logic and close the div.
However the problem occurs when my AJAX returns too many results to display in the set size of my div. When this occurs my div becomes scrollable. When the user is interacting with the scrollable, it seems to fire the onmouseout event because the div disappears.
I'm currently working on a pretty straight-forward AJAX application. In this application, I get some XML, and then parse it. An example of what I'm working with is as such: <?xml version="1.0"?> <postRoot xml:lang="EN"> <post type="comment" date="January 1, 1970"> <user>athlon32</user> <content>Hello World</content> </post> </postRoot>
Now, I've been able to read the XML with XMLHttpRequest , my trouble is with parsing the results. I've tried tons of things, but I just can't seem to get the different child nodes. Now, let's say we have something like this: var xml = xhr.responseXML; var allPosts = xml.getElementsByTagName('post'); Could I use childNode to access user & content? And if so, how? I've tried many things, but nothing is working :/ Is there a better way to parse the results I get back from the server?
So I'm loading the div#my_events by prepend(data) where "data" is another well styled div. Is there anyway to animate this returned data. Unfortunately I can't just specify a unique ID on the incoming data. So I was wondering how else I might be able to address this data I'm returning.
It is basically a topic list, with a modal that sends jquery to add a topic to the database, and returns the topic from the database, hides the modal, and displays the last added topic at the top of the topic list. Now I'd like it to do something slightly fancy like animate the color of the background to bring the user's attention to it.
I define a "click" event on "a" tags in the ready part of a page. It fires just fine when I click on any "a" tag on the page. I then have a button which sets the content of a div using ajax. This content contains a couple of "a" tags. The issue now is that the "click" event does NOT fire when clicking on these tags. I suspect it is because they did not exist when the page was initially rendered. What is the "JQuery way" of dealing with an issue like this? Of course I cannot be the only one in the world who needs to return HTML with events from my ajax calls :-)
In this dumb example, I'm unable to match the 'data' returned variable with the value I assigned to it in php (I can't manage to enter my 'do stuff'), yet its value is 'ok' if I display it. I have no problem to retrieve html code from php and inject it in my pages, but I can't test it as a regular javascript string.
What's wrong in this ? What have I missed about the 'data' format ? Do I have to 'cast' data to a javascript string (and if so, how ?)
but this has not worked. the latter showed that jquery is inserted in the index. the main page that calls the button. jquery in a home can act on an ID loaded from another file with ajax?
I am currently using $.ajax to post to a Perl file that queries a webservice and returns XML. Running the Perl via command line confirms that XML is being returned with Content-Type: application/xml. However, regardless if I set the dataType parameter to "xml", "XML" or just use jQuery's intelligent guess, it appears that I am not getting any data returned to my function at all.
I've tried using the full $.ajax notation and the simplified $.get notation as follows:
and:
I have also tried using JQuery to perform a "GET" directly to the webservice which returns XML by default and still I get no data returned to my function.
Although I doubt it's browser-related, I have confirmed this in both Chrome (5.0.375) and Firefox (3.6.3).
I want to update an element in my DOM that contains Javascript code when an action X is performed and an AJAX response generated with new Javascript code that is one of the AJAX response variables.
The AJAX request is successfully returned, as is the Javascript JSON response variable. However, I'm having no luck updating the DOM element containing the old JS code with the new JS code. I'm performing these operations using JQuery.
