JSON Accessing "numbered" Object Values?
May 10, 2011I guess I'm really thick, but I am going crazy with this JSON object:
Code:
var json={
"item":"random",
"results":{
"1":"test"

I guess I'm really thick, but I am going crazy with this JSON object:
Code:
var json={
"item":"random",
"results":{
"1":"test"
[Code]...
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 .
I've got the following code:
[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; ?>",
[code]....
What are the different methods of selecting some of the values in the json object below:
what different selecting methods can you use to get the date, or the views?
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).

It depends on being able to access properties of an object's linked objects (a bit oddly worded, sorry)...Problem is I'm not sure how to properly access those properties... see below please.

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.

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:

I have a javascript function that needs to access methods of a java
object(localTag). In my JSP I'm trying to include hidden fields for
the Strings returned from the getter method calls of the object like
so:
<html:hidden name="FrmCustomerHolding" property='<%=
"localTag.getTagName()" %>' />
<html:hidden name="FrmCustomerHolding" property='<%=
"localTag.getTagValue()" %>' />
If I can do something like this, what is the correct syntax and how do
I access this property in my javascript? When I have a hidden field
that is just a String, I access it in the javascript like
"document.getElementById("theString").value" and it works fine, but I
can't seem to find how to access the String value of a method call.
I seem to be rather bad at formulating my questions, so let me try another way; given the following:
DOM:
DOCUMENT

How do I get/set that textarea value?
I have the following code:
A = {
"value": "a",
};
B = A ;
B.value = "b";
alert (A.value); // => b
I expected A.value to be "a". how can I change values of a new object, without changing the parent-object?
i have a php page in which i have a listbox as below:
<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?
jquery code:
$.ajax({
url: "validate_livestock_form/index/",
type: 'POST',
dataType: "json",
data: form_data,
success: function(data) {
alert(data);

php page is echoing out:{"species":"Please select a species!"} I double checked the response from the php and firebug shows the same. On success alert is not alerting the JSON data instead, I'm receiving [object Object]. Why is that and how do what should I do to fix this?
What it is supposed to do is pull down the background image of my nav panel by setting the CSS height to match the length of the page. I got it to work in IE but it does not work in Opera or Firefox. I'm not sure how to access the correct object in Opera and FF.
To view the problem:
Well, I'm a new user so I can't post the link to the problem.
And here is the code:
I have an object that defines the default color, and then when the color is updated, the different css classes need to be updated as well. So here's what I was trying to do
var colorPicker = {
mainColor: "red",
backgroundColor: this.mainColor + "bkgd",
}
So problem 1 is I keep getting "undefined" returned for "this.mainColor". If I use colorPicker.mainColor, it hasn't been created yet so it throws an error.Problem two is if I update mainColor from another function, say to make mainColor = "green", then backgroundColor doesn't automatically update.
I am fairly familiar with the concept of Objects and their properties and methods, but javascript being object based as opposed to object oriented has me stumped on how to access an object's properties from an onclick event handler created for another object created within the original object.In the example below, I have a constructor function called anyObj. to which I pass an object reference to an element.
anyObj has 3 properties and one function increaseWidth()
increaseWidth() creates a new button with an onclick event handler and this is where I have a problem.The onclick function needs to increase the value of anyObj's this.width property. I originally had a line this.width += 10; in the onclick but quickly realised why this wasn't working because the this in the onclick function refers to the new button object and not the this.width property of anyObj.
The workaround I have used, and it works, is to make a copy of all the this.xxxxx properties. eg. width = this.width; and use the width variable in the onclick as you can see below. This "workaround" works fine but doesn't feel ideal to me.So, what I am asking advice on is, is there a better way to access the anyObj()'s properties from within the onclick function than the way I have done it? Obviously I would prefer to not have to make copies of all the anyObj() properties like I have to make them accessible to the onclick function.
Code:
function anyObj(divObj){
this.elem = divObj;
this.width = 50;

View 1 Replies View RelatedI'm a little puzzled over the possibility of accessing an array. I've declared the previd id - in the proxy.invoke call which works just fine (we have already implemented an .each loop which also works. My problem is this - after accessing the proxy.invoke function, the previd is populated correctly with push but after the call, we cannot seem to access the previd array to make a join to a string. Here's the basics of the code.
var previd = [];
proxy.invoke("validdateIDCard", p_caregiverid,

I have an object whose name is mural. I have assigned the name mural to the title of an anchor element. When user clicks and element I want to store the title of the anchor in a variable called sprite. I then want to access that object whose name corresponds to the sprite variable string.
Here is my code:
HTML Code:
var mural= new Object();
mural.top='0px';
mural.left=-'510px';
var stamps= new Object();
stamps.top='0px';
stamps.left=-'1886px';
var sprite=$(this).attr('title');
$(".image-holder").css("background-position",'sprite.top, sprite.left');
It's not working because the the variable sprite is just a reference to $(this).attr('title'), how do I make it reference the object? Oh and I know that .cc jquery statement probably wont work, I'm not sure yet of the correct way to have two values that don't need quotations in as the second argument.

I have just started to learn about JQuery and wanted to learn how to retrieve data from an API.

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?
