JQuery :: Accessing Nested JSON Values And Using It In Template?
Oct 13, 2011
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 .

Server-side code returns a JSON representation of a query like this:
{"recordcount":3,"columnlist":"messageid,messagetext,dateposted,firstname,lastname","data":{"messageid":[3,2,1],"messagetext":["hello? is this thing on???","what? why?","Hello, and welcome!"],"dateposted":["{ts '2010-12-05 11:32:51'}","{ts '2010-12-05 11:32:17'}","{ts
'2010-12-05 09:44:30'}"],"firstname":["Mortimer","Tom","Waldo"],"lastname":["Who","Dickenharry","Emerson"]}}
Makes sense, and jQuery converts it to the equivalent javascript object when it comes back in an AJAX response, but I'm having trouble using that with the template plugin. It apparently expects an array of individual objects, each with a field for each query column.The server response is an object containing recordcount, columnlist, and data members, where 'data' is an object keyed by column name, whose values are arrays with the data for each record. It's equivalent, in a familiar format, and a much more concise representation than the javascript for an array of individual objects, since it doesn't repeat the column names for each row, but it's not the same.

I guess I'm really thick, but I am going crazy with this JSON object:
Code:

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).

I've got the following code:

I was just wondering how will I be able to access the content of the data variable in script.template.php?
The other problem is that when I use the $.getJSON method (instead of just $.get), the script doesn't appear to get called.

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:
console.log(data.var1)console.log(data.faves.var1)
console.log(var1)
All to no avail. Can anyone tell me what I'm doing wrong here? I have checked with FireBug that all the data returned is good and well-formed etc.
$(function() {
$.post("<? echo base_url(); ?>test.php", {
id: "<?php echo $id; ?>",

I have a form that allows for dynamic field creation. Basically, you click the + button, and an addition row of fields (2 text fields) are created. The area that is dynamically created is wrapped by a <div id>, within which is, and this might be bad practice so please feel free to mock me , another few nested div id's. It looks something like this:
Code:
Each time you hit the +, it creates a new div id beneath the "Adds" id.
What I'd like to do is see the values of the id's "row_fqdn" and "row_ip". Is there a quick way to access the values of nested id's?
I found a workaround but it seems pretty messy and drawn out, something like this:
Code:
I'm looking for a way to do something like this:

But that doesn't work.

I have a form which has a few submit buttons, all named SubmitButton so I can pass the clicked button's value through to the submission processor and then act according to which button is pressed. However on the jquery form submit even, I also want to check certain things before I fire the submission off. As the button isn't a "conventional" input I can't check the document object to see which one was clicked, so I need to check the form contents that are about to be submitted, can I do this from the submission event or will I have to bind to each button individually?

I have just started to learn about JQuery and wanted to learn how to retrieve data from an API.
I used the Flickr example provided here [url] and just changed the relevant code to point to the 500px api.

If I launch the following URL I do get the results properly [url]
Here's a sample of what the result looks like:-

i can't sucessfully get the values out of the <select> and <option> elements in my HTML page. This is really annoying because i am using the same code as i always use. And infact, it is identical to the code in a previous project (a Product Quote Calculator). It should work, but for some reason it doesn't. The Error Console is telling me that that element's value is "null". However, i have used the DOM Inspector, and it is not a null value (as the Value="3" is set - the DOM inspector also verifies this). There is another problem, but i'll leave that for another posting *grin*. I'll still be working on that one until someone gets back to me on this problem. Anyways...here's the code:
the code is actually a bit long, so i added it as an attachment. maybe it will fit into a post window.

<title>Sketch Book v1.0</title>

<script Language="JavaScript">
var SketchDataFolder = "c:data.txt";

I am undertaking an assignment where I have to create a webpage that reads values from a database, and generate the appropriate amount of sliders (scroll bars) according to the number of database entires. The webpage functions like this: On index.php load, it reads all the slider values from the database and automatically generates and sets each slider to that value On setting each individual slider to a new value by adjusting the slider, the code automatically updates the slider value in the database via AJAX.
So far I have gotten both functionalities to work successfully. There is just one problem with the 2nd functionality. I can only get one slider value to save to the database at a time. I know how to fix the problem, I just do not know to achieve it. I shall now illustrate via snippets of code:

<select NAME="scopeid[]" id="scopeid[]" class=sel1 multiple size=4>
<? while ($qrrs=mysql_fetch_assoc($qrrid)) { ?>
<option value="<?=$qrrs['scopeid']?>" <? if($db->isinarray($scopeid,$qrrs['scopeid']) ){ print " selected "; } ?>><?=$qrrs['scopedescription']?></option>
<? } ?>
</select>
<input type="button" name="add" value="Add" class=button onclick="Add()" style="width:40">
how do i pass the values of listbox[] to javascript?
below is my javascript:
function Add() {
Obj=(document.getElementById("scopeid[]"));
alert(Obj.value);
}
alert gives me only the last selected value and not the entire values. i.e if the user has selected 2 ,3 and 4th option, it gives me value of only 4th item instead of all three. how to do it?

I'm using the plugin jquery-tmpl. Is there a way to specify a callback after a template is run? I want to do something like
<script id='itemTemplate' type='text/html'>
