I am fairly new to javascript and I am wondering how I would load a text file that has a JSON formatted array stored in it?I can pass the array directly to the page via php though I want to be able to store the data and save on calls to the database and of course load the data dynamically to the page.
Is Json considered the better file format for loadind data via Jquery AJAX? I am going to use it either way, but from a cutting edge stand point, is JSON looked at a more cutting edge since it loads faster. 2. And for that matter is anyone using css3 and E4X? All these seem to require the latest versions of all browsers. Since my goal is to be cutting edge I was thinking to do some stuff in the above listed that require only the latest browser if it is detected, if not use what works in most all browsers? What are cutting edge web app developers really doing at this time?
My plan was to insert an HTML string from a JSON file into the DOM. As an example for the format, see [url]. I was wondering how I could get the parse.text['*'] inserted into the DOM.

I am trying to create a playlist from the youtube data api using jquery's getjson method. I can get other nodes from the feed, but I can't get the media title for some reason. This is the feed:and this is the code that I'm using:
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:
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 have some DIV elements having some ID and content in it .. for example
I have submit button when I click this ... I should generate a JSON data structure like this
I need to POST this on submit button clicking.... I have seen some serializeArray() function but it works well for form based elements, I have created some string based structure in which I am printing the single quotes and double quotes like this fashion by creating a array and pushing itvar result = new Array();
Is there any short cut to create JSON with this datas ...
<script type=text/javascript> function hide_tooltip(){ var hp = document.getElementById("tooltipper"); hp.style.left=0; hp.style.top=0; hp.style.width=1; hp.style.height=1; hp.style.padding=0; hp.style.border=0; hp.innerHTML=""; } function show_tooltip(event,wid,ht,txt){ var vp=document.getElementById("tooltipper"); vp.style.border="1px solid black"; vp.style.left=event.clientX+25; vp.style.top=event.clientY-1; vp.style.width = wid; vp.style.height = ht; vp.style.padding=10; vp.innerHTML=txt;

Is there any way to insert a NewLine in the text string to control the formatting of the text in the window??
I have a dynamically-generated menu, that resides in an unordered list. I want to be able to change the font styling for only one of the items (make 'contribute' red instead of blue). I thought it might be possible to explore the UL through DOM, and then write some css inline if the string matches. Does this make sense, and if so, anyone have any thoughts on how I would do this?
I have thought about using the standard email checker pattern but we have had problems in the past so looking to check if the string follows these simple rules.
has no spaces, has a character/s at the start followed by an @ then has a character/s followed by a (dot) then another character/s
i.e a@a.a aa@aa.aa aaa@aaaaaaaaa.aaa
i am not sure how the standard pattern works but feel that it may be to complex which causes some email address to fail.
I use $.getJSON for all my ajax stuff and it works beautifully but there is one particular situation where I use an iframe hack to do an ajax file upload and even though the returned value is a json object (created with PHP), jQuery treats it like a string. I'm using json2.js right now and it does the trick but I don't like including that much extra code because of one rare situation. So my question is, be it with $.getJSON or by specifying 'json' as the expected return type of an ajax request, jQuery *seems* to be able to convert into json. The string returned is already a json object, I just need jQuery to be able to treat it like one. I've tried wrapping it in a jQuery object but no use. (and I really don't want to go down the eval() path)...
I am slowly working through learning/writing a JS project.here is the core issue.:
var pt =<? echo json_encode($prt);?> alert(pt) // for diagnostic purposes
json is flattening the PHP array to be used in the script.However, the alert shows me that I only get {[ ,which is just before the first set of double quotes.JS quits at the double quotes, leaving me with an undefined array.How do I fix this?
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'm a beginner in Jquery and I have a big doubt, follow at bellow the code to be better viewed: The method below is static and Static methods do not work with instance, For this reason I passed the 'nameLabel' that the typeis Label by parameter, however I need to catch the exception and show it to the user.
But I'm using Jquery and this method is used in a Ajax Request and I use the Json to pass the datas, how showed below: var idCliente= $("#<%= txtIDCliente.ClientID %>").val(); var nomeLabel = $("#<%= lblMensagem.ClientID %>"); var poligonal = "{ idCliente: " + idCliente + ", + lblMensagem: " + nomeLabel + " }"; But the problem is that I need to pass in my Json the nomeLabel with Label, but always a problem happen, because the same is showed like 'indefined'. How to solve this situation?
I have a string that is like [{"carePacks": [{"businessCode":"J1PS","description":"HP 1"}],"coveragePeriod":12}, {"carePacks":[{"businessCode":"J1PS", "description":"HP s"}],"coveragePeriod":13}]. How to convert it to a json structure and how to get data from the data structure, like get "HP 1".
I am really stuck in parsing a JSON string and take it's values. I got the json string as
