So I can't for the life of me understand JSON. I've looked through numerous links but nothing. If I have a Database and all I want to pull is:
How do I print that out to an HTML document using JSON. I don't get it. I think it puts it in an array but how does it get there? Do I just print it out like I would a normal javascript array? If this isn't quite the right place to post this I apologize but there wasn't an AJAX section.
I am new to Ajax and have a bit of a gap in my understanding. I have a status monitor that sets a JS function to run every second with setInterval. When the document loads, I will need to get data from the server asynchronously (I wont know the info before hand) and use that data to set id values to find them as nodes and change them later on.
The problem is as I see it, that the callback function I will use to grab the initial data is coming back via a JSON object. The callback function is done with javascript. So, how can I take the JSON data, or converted to javascript data and set my ID values when the document loads? If I change the values dynamically with the DOM, will those values be reliable enough to use as my other recurring functions find them and set their innerHTML properties?
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 am doing a project now i going to use ajax to retrieve coordinate from the json in html and pin the coordinate onto a point on the map using javascript but the problem is i am only able to use one point on the map can tell me what to add in ? or how should i change it with? it will be nice if u can change the code from the below and show me how

View 1 Replies View RelatedI 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?
so, the pseudo code: - on change of input contents, check to see if two input fields are set - if set, update a third field with "loading..." text and a loading gif - use ajax to send data to a url, and get a calculated json response - update the third field with the calculated response
I know I'm getting the correct response, according to firebug: {"pace":"10:00"}
the code:
$('#run_distance').change(function() {
if ($(this).val() != '' && $('#run_time').val() != '')
{
$('#run_pace').val('Calculating Pace…');
[Code].....
how to update the #run_pace input field with the json response.
Is there a way to print (sending to printer) the partial contents within the HTML file
Ex: Can i print content of div2 only?.
in my project I'm using following javascript code to print my page
<script language="javascript" type="text/javascript">
function CallPrint(strid)
{
var prtContent = document.getElementById(strid);
var WinPrint = window.open('','','letf=0,top=0,width=1,height=1,toolbar=0,scrollbars=0,status=0');
WinPrint.document.write(prtContent.innerHTML);
[Code]...
how can I know printing document is finished ?
I need to know this one. How can we get printer status using JavaScript and also how can we give MS word document print command using JavaScript.

View 14 Replies View RelatedNormally an SVG document is loaded/parsed/interpreted inside an HTML
document using an 'object' (or 'embed') element, although there are
supposedly other ways too. The problem is, the SVG document must be
static this way.
I want to use the DOM interface to build SVG dynamically inside an HTML
document. I am guessing I can build it inside HTML within an 'object' (or
maybe 'iframe'?) element.
My intentions/goals:
In Javascript, I construct an object 'embedSVG' which has properties and
methods for creating valid SVG elements and setting their attributes and
attribute values.
During construction, the SVG document is created with its root element.
During debugging in FF 2.0 (I'll work on an MSIE-compatible format later),
I am using the Mozilla DOM Inspector and comparing nodes when the
'object' element is loading a valid external SVG document, and when I am
appending the child representing the SVG document created by the DOM
functions.
However the child node (#document) does not specify 'svg' as the root
element, but instead 'HTML'. Something is not working.
Here is the relevant code in 'ScriptTest.html' which is the HTML in which
the SVG is supposed to be embedded. Below it is the relevant code for
'svglib.js' which is supposed to contain code for building the SVG
dynamically.
What this code is supposed to do is load the HTML page and execute the
anonymous script, and draw a navy blue-bordered yellow rectangle on a
blank page. This is similar to the example in the SVG 1.1 W3C
Recommendation on page 202 of the 719-page PDF.
I am getting an exception when embedSVG object placeInHTML() method is
called: NS_ERROR_DOM_HIERARCHY_REQUEST_ERR. I find in DOM Inspector in
spite of or after the exception that a document is placed as a child of
the object element, but it is HTML, with a default 'head', 'title',
'body' elements placed.
Where am I blowing it?

The problem with using HTML as a report writer is primarily the
unreliable page breaking.
However it is a rather handy way of writing reports with images

I could generate say 10 HTML pages of a maximum length to fit a page -

i'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?
