JSON.stringify() Acceptable - Send All Of The Data From These Objects To PHP
Apr 27, 2010
I'm working on a very Javascript heavy application, and we've set up a number of different Objects to handle the data on the page. Very often, we'll need to send all of the data from these objects to PHP. Right now, we're using JSON.stringify. Are there any issues with this? It seem's like it does exactly what we need, but are there any downsides?

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 am currently generating two different JSON objects from Coldfusion. I've read several things about how to merge JSON objects but they always modify the first object if it has the same Key. What I want to do is append the second objects contents to the end of the first objects contents under the same key.

Im having difficulty getting my form contents to send to my php page using ajax, jquery and json. The results just doesnt want to show.
My javascript, where I create the JSON object and try to send it through to the php page:
var JSONobj;
var JSONstr;
function createJSON(){
[code]....
What should happen is the firstname should be alerted. But the alert box doesnt even show and I find no errors using firebug...

whats the best way to pass a json string to the server.
if my jsonstring = {a:Ƈ',b:'sds',c:'sdg'}
could i send that to the server passing it as 1 variable like so:
url = /serverside.php?json=jsonstring
or would i have to break it down into something like this:
url = /serverside.php?a=1&b=sds&c=sdg

I have a web service that accepts application/json but returns HTML to place in a DIV. I am not having any luck configuring the .ajax call so that it both POSTs in a format accepted by the web service and does not attempt to validate the HTML response as JSON.
[Code]...
It would seem that I cannot have anything other than 'json' in the dataType, even though from the docs it appears that this only affects the interpretation of the response, changing it's value to 'html' causes the web service to reject the call. I've also tried a converter but perhaps I'm not using it properly. Is it possible to use jquery to post JSON and get back HTML? What configurations am I missing?

i just leanerd the existence of the ajaxSubmit jQuery plugin,im wondering if there is a way to use the JSON both to send and retrieve the requests .I mean, no the plugin have the option 'dataType',that is used to specify the format that the server will send back, but i need to send the form as jquery to the server.For example, if my form looks like:
<form name="mytest" action="mypage.php" method="get">
<input type="text" name="firstone" id="firstone" value="here some
text!" />[code].....

I've been pretty infatuated with JSON for some time now since
"discovering" it a while back. (It's been there all along in
JavaScript, but it was just never "noticed" or used by most until
recently -- or maybe I should just speak for myself.)
The fact that JSON is more elegant goes without saying, yet I can't
seem to find a way to use JSON the way I *really* want to use it: to
create objects that can be instantated into multiple instances without
prototyping. I've seen (and used) JSON for singleton object instances
-- this not a problem and this is how it works right out of the gate.
But given the following custom object written the past "normal" way, I
would like to write it in JSON format, and then be able to create new
instances from the one definition. Here's an example using the "old
way" most who have been writing JavaScript for years have seen:
function Two( x, y ) {
this.x = x;
this.y = y;
}
Two.prototype.sum = function () { return this.x + this.y }
Two.prototype.max = function () { return this.x this.y ? this.x :
this.y }
Two.prototype.min = function () { return this.x this.y ? this.y :
this.x }
Two.prototype.pow = function () { return Math.pow( this.x, this.y ) }
Now, I know I can get all "fancy" with the above and do either this:
Two.prototype = {
sum : function { return this.x + this.y },
max : function () { return this.x this.y ? this.x : this.y },
min : function () { return this.x this.y ? this.y : this.x },
pow : function () { return Math.pow( this.x, this.y ) }
};
Or this:
function Two( x, y ) {
// Properties.
this.x = x;
this.y = y;
// Methods.
this.sum = function () { return this.x + this.y }
this.max = function () { return this.x this.y ? this.x : this.y }
this.min = function () { return this.x this.y ? this.y : this.x }
this.pow = function () { return Math.pow( this.x, this.y ) }
}
(The later seems to work without prototyping...!)
But neither are really as close to pure JSON as I would like, so that
I can instantate those:
var hisPair = new Two( 11, 22 );
var herPair = new Two( 33, 44 );
What I'd like is a way in PURE JSON to be able to create the Two class
(as an example) using pure JSON. I've not seen anything yet on the
web that addresses this directly aside from some pages which require
you to include another JS to allow "deep embedding" of classes using
other helper "classes" (that are created the "old way" it seems), etc.
The best I've found so far on using pure JSON to create a class that
allows *multiple* instances is something like this:
function Two( x, y ) {
var class = {
x : x,
y : y,
sum : function { return this.x + this.y }
max : function () { return this.x this.y ? this.x : this.y }
min : function () { return this.x this.y ? this.y : this.x }
pow : function () { return Math.pow( this.x, this.y ) }
};
for (var element in class) this[element] = class[element];
}
Now *THAT* works, but it's still not as "pure" I would like. But it's
acceptable for now, I guess, since I *am* creating the entire "class"
as a JSON object, and I consider the outside function "wrapper" as the
necessary "constructor." But I keep wondering... There HAS to be a
better way.
I'm just wondering if anyone knows of a place that discusses JSON used
in situations like the above. Again, I've seen an ABUNDANCE of pages
and sites that discuss JSON in Singleton usage, but nothing that
discusses it as I am wanting here.

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:
{"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
html looks like this:
<div class="Name"></div><div class="Age"></div>
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.
var jsonData = {"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
$.each(json.Super, function() {
$('#box .Name').html(this.Name);
$('#box .Age).html(this.Age);
});

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.
<body>
If I launch the following URL I do get the results properly [url]
Here's a sample of what the result looks like:-
I don't get any results when I run my code page. What am I doing wrong?

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'm making this ajax call:
Code:
url = "/GeoAdaptaApp/geoLogger/logGuiEvents?json="+aLotOfJSONStuff;
encUrl = encodeURI(url,"UTF-8");
new Ajax.Request(encUrl, {
method: 'get',
onSuccess: this.sendQueueToServerSuccess( this,logConsole ),
[Code]...
The JSON string seems correct (I checked it with a validator) and it worked on an Ajax.updater (but i need a request now). Firefox keeps telling me:
[Code]...
The call always end up in the onFailure block. Full request here: [URL] It's very strange, Is there a better way to pass json objects to the server?

I'm trying to send data to 2 different functions using the same selectbox. 1 function only needs a "ID" as value like this:
Code HTML4Strict:
<select name="ccountry" onchange="getState(this.value)">
<option value="1">USA</option>
<option value="2">England</option>
</select>
The other one needs an url like this:
[Code]...
I have an idea, but not sure how to do it... If I use the last example and then somehow in my javascript function would be able to, like in php, extract the code=1 so I would get only the "1"...

I wonder, what is the simpliest way to send data to PHP script from Javascript? For example, user clicks some image and JS runs some PHP script in background (so browser keeps loaded page) which makes few MySQL queries etc.

I'm reading the content of a local binary file with the method mentioned here: [URL]
Then I'm getting the data as a string where each character represents the binary value. I have successfully sent that string with Mozilla's XmlHttpRequest's sendAsBinary method, but IE 7's version doesn't have that method...
Using the send method almost works, the only problem is that binary content can be represented as the asciicode 0. This means that the string read by sent is cut off as soon as it is encountered. That means that the part before the first NULL character (asciicode = 0) is successfully sent to the server.
The solution I have made right now is to increment each character's asciicode on the client side by one and decrement them on the server before converting the character to the binary representation. The downside with this is that the size of the data sent between the client and server gets larger than the original filesize. Ex: 8kb file grows to ~12kb.

I would like to send my form data to a php file but not to get any response. I want to send an ID so that PHP can do MySQL search and generate a PDF file. Problem seems to be that PHP is responding something back to HTML and that is messing my code. So I just want to send the data and run the scripit in PHP so that nothing is returned back to HTML.

The script below works, but only returns one headline/url from the html list.I am coming from a procedural background and know there must be a better way to pass all the urls and headlines (the link text) to my PHP script, which populates my database, but even after reading 'Jquery in Action' I am flummoxed.how to attack this problem? The .each portion of my script does not seem to work as I expect it to. I have also tried append, which would seem to be a solution ... really all I need is the "which" value from the url, so passing a simple array of those values to PHP would suffice.
<SCRIPT>
$("#latest-news button").click(function () {
$.each(function()[code]....

I have been using Ajax to send data to php scripts and I would like to send text data from a textarea of a form. Normally I send data to the script with the following code...
How can I send larger amounts of data to the php script? Can the url contain 750 characters? I think the limit is 255 characters.

The purpose of these scripts are to allow you to send forms using javascript. If your server doesn't support scripting languages like php or perl, or if you are unfamiliar with those languages, then this is an easy alternative for you.
When you send a form using the mailto: command, the data gets sent using the post method and in the process gets reformatted. When you receive the form data in your email it will contain hexadecimal characters, spaces will be replaced with + signs, and each value will be separated by an & sign.
You have two options when sending a form with javascript. Either you can reformat the data before it's sent. Thereby creating an email that is legible upon receiving it. Or you can reformat the data after you receive the email. I have posted both methods on this page.
Option 1: REFORMAT AFTER
Create your form using the following syntax:
<form name="NameOfYourForm" method="post" action="mailto:yourname@yourdomain.com">
<!-- your input tags go here -->
<input type="submit" value="Send">
</form>
Then download the attachment to this post. Open the file in your web browser. When you receive the email containing the form data, just select it all and copy it. Then paste the data into the "hexadecimal value" box. Click decode to convert it to ascii. Then click split to remove +'s and to split data onto multiple lines. Use the "add html" checkbox to make the output viewable in your web browser.
NOTE:
The first input tag that you use in your form will become the <title> if you use the html option. So if your first input tag is name="Name" value="Joe Smith" then the html title will appear as <title>Name: Joe Smith</title>.
