JQuery :: Accessing An Element Within JSON Retrieved Data?
Apr 1, 2010
When retrieving JSON data I'm able to access individual elements using the $.each() function and iterate over them. However, how would I access just one element by its location and not by name? (i.e. data(0) not data.ID).
In the code below the second alert is executed before the first one making it show the "empty" content, and not the result from the .json file. Why, and how can I make it work? getjson.html file
Simple. The problem is that the effect works on elements already written in the main page, but not onthe elements that come from the asynchronized html! How can I apply the effect on the "new" code too?
The scenario is : I have to fire an ajax request, get the json values and populate the page using jQuery template.
I'm able to fire the ajax request and in the success function I'm getting the data also. But I'm not sure how do I proceed with the Nested JSON data that I have received. I am passing it to the .tmpl() function but nothing seems to be working.
Here is the json data that I receive :
{ "activity": { "date": [ {
[Code]....
It also gives me an error sometimes that says "c.tmpl is not a function" which is linked to the jquery.tmpl.min.js .
The below code posts a couple of vars to a php file which sends back a json object containing (in the test case) one object called 'faves' with 2 variables (let's say called var1 and var2). I can't seem to access the variables after the ajax call. The result is always an 'undefined' error message. I've tried:
I have a JSON structure in API.When I call the API in my code it returns as the same JSON .I have to print this JSON result as table with pagination in Javascript. The table should be dynamic with previous and next buttons and the table should populate the results according to the JSON and each page should have 20 entries and then the remaining entries should go on the next page and I should be able to go back and forth in the table using previous and next respectively.tell me the exact code of how to start with getting JSON from the API and then write the JSON data in the form of dynamic table with pagination.
I have a html file that I want to load, loop through the json data and for each json entry I want to add a new block of the html and insert the json data into the matching div/class of the html. json looks like this:
So for each json entry of name/age, I want to insert that into the html, and then add another row, until all json data has been fetched. After this I want to insert all of this into #box, which is just a divthat should contain that html. Looping like this obviously does not work, since I just keep replacing the same html through the loop.
it seems to be a problem if I need to access data() of the elements from another window, like for example $(anyElement,window.opener.document).data() which returns null when in fact there is some data actually stored. I heard that data is stored in the $.cache, which is window-related, so that's understandable, but how can I work around that?
Certain plugins that use $.data no longer work correctly because of that. E.g., I can't use linkselectmethods on linkselects located in the window.opener.document. Again, is there any workaround?
I'm trying to compare incoming JSON data to the existing data to see if there are any changes, but for giant objects like:
Code: [{"date":"2011-09-03 23:06:03","notifier_id":"1","type":"1","unread":"0"},{"date":"2011-09-05 00:37:46"}] if (JSON.stringify(oldData) == JSON.stringify(newData))
This doesn't seem to work. I've tried using:
Code: escape("'" + JSON.stringify(W.notification.list + "'")) but that ignores the objects properties and returns something like 22%5Bobject%20Object%5D%2C%5Bobject
I have 3 Jquery tabs on the form. Each tab contain same HTML Tables, I want to access the data in a Cell of a table in an active tab on the button click
in normal Case I use
var x=document.getElementById("searchResultTable").rows[10].cells; referenceNo=x[2].innerHTML;// get the value in the Cell alert( "x[2].innerHTML);
if i use this Code i get only the First Table data .All the Tabs Contains Same Table with Same Id and Name
In a project repeated blocks are identified by an <input type="hidden" value="x" /> field. To get an access to one of the block I wanted first access to that field. My first problem is there and I will explain it by a micro-project (tested with Firefox only)
Here is the HTML code : <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=utf8" /> <meta http-equiv="Content-Style-Type" content="text/css" /> <meta http-equiv="Content-Script-Type" content="text/javascript" /> <link rel="stylesheet" href = "index.css" type="text/css" /> <script type="text/javascript" src='Library/jquery-1.4.js'></script> <script type="text/javascript" src='index.js'></script> .....
And here the javascript code wher is the JQuery question //meta http-equiv content-type charset=utf8 function test(){ var $id = $('#curUnion').val(); var $objet = $('#toutesUnions > .pseudoFieldset').find('input[value=$id]'); var $test = $objet.val(); var $objet2 = $('#toutesUnions > .pseudoFieldset').find('input[value="1"]'); .....
With $id = "1" as shown by the Javascript debugger (in Firefox) where is the difference between find('input[value=$id]') and find('input[value="1"]') Giving the alert result => undefined / 1 If you want to test the micro project you will find it in the Test.zip joined. How to access the immediate parent pseudoFieldset to get its html code?
I am trying to access an element in a page using ID using jquery in when the document is ready.But the problem is the length is always 0 even if the script tag is in the head or right at the bottom of the page. The element is seen rendered when I see it using FireBug.an someone point out where I am making a mistake accessing the element
I think I have a varialbe scope problem here, but I can't figure it out. What I'm trying to do is extract a piece of data from a JSON file using a variable established earlier in the script as one of the keys.
When I run this script I get the alert that lets me know that the variable "theMappableItem" has been established correctly. I click "OK" in the alert box. Then in my console (in firebug) I see a line showing that the .json file has been gotten successfully. Next in the console is an error that says:
and i want to access the element dropSubPrd that is inserted on that ajax function, on the div FirstResult, but it will not work in $('document').ready because when the page load's that element isnt there.
I'm a complete newbie to JSON and I'm trying to make some sense out of itI think that what I want to achieve is fairly basic, but I have no clue where to begin. Here's my problem:I want to get the information from this JSON-string, fetch the value for realm_rank and display it within a header-tag in my html-code.
I have used getSON() successfully before but I am meeting with an issue which I don't seem to get a hold on. The data object returned is not populated correctly by getJSON(). Am I doing something wrong?
I am new to jquery and JavaScript in general and I want to access data in Google Spreadsheet. So at first I published a spreadsheet to be able to retrieve a JSON feed like mentioned here: Simple example of retrieving JSON feeds from Spreadsheets Data APINow I can get a JSON-File - the specific file is this: My Google Spreadsheet JSON
But I was not able to display any data as of now. My code looks like this: <!DOCTYPE html> <html><head> <title>the title</title> <script src="[URL]" type="text/javascript"></script> <script type="text/javascript"> jQuery(document).ready(function() { jQuery.noConflict(); // probably I need this because in the JSON-feed there are $t-objects jQuery.getJSON("[URL]", function listEntries(json) { var content = document.createTextNode(json.feed.entry[2].title.$t); jQuery("p.inhalt").append(content); });}); </script></head><body> <p class="inhalt"></p> </body></html> So if this looks like noob-code - it is. How the code should look like if a wanted to access the data in the spreadsheet?
I'm trying to update a table based on the results of a database query returned via JSON. My goal is to show the progress of a queue, removing entries that have completed. Firstly I need to populate a table with the results of the JSON. I have:
