Fetching Data From Other Web Pages

May 14, 2005

Is there any way I could fetch data from another web page?

Things like current weather, and rate of exchange?

I would search the data for example by

-loading a web page somehow (IFRAME?)
-going through all <td> tags in it and
-if the <td> had a spesific text, like "weather in Fooland" then
-I'd jump to the next <td> tag and take the text inside it, that hopefully had the data I was looking for.

I used an IFRAME to load a web page. It's id is called "myiframe"

var myIframe = document.getElementById("myiframe")
var iframeBody = myIframe.body;
var paragraphs = iframeBody.getElementsByTagName("p");
document.write(paragraphs.length); //this writes 0!
the page I loaded on the IFRAME has paragraph elements right on body. Why can't I find them?

I tried using node iterator (document.createNodeIterator() ? ) too, but that didn't work at all! I tried it without the IFRAME too. If you have any guesses what it might be, please tell me. Should it work in Mozilla? Should I create the node Iterator only after the page has finished loading?

JQuery :: Fetching Data From Callback With $.ajax?

<span style="font-family: courier new,monospace;">Hello all,</span><br style="font-family: courier new,monospace;"><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">I've recently started with jQuery because I wanted to use it for posting details from an login form to a PHP script which should return whether the user is authenticated ox not.</span><br style="font-family: courier new,monospace;"> <br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">For this I use $.ajax, because of it's flexibility and I prefer to use it in this implementation. Reading (jQuery docs and examples) and searching a lot did not solve me on one issue: fetching the data in the callback to the global scope.

</span><br style="font-family: courier new,monospace;">
<br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">Here is the code:</span><br style="font-family: courier new,monospace;"><font style="font-family: courier new,monospace;" size="2"><script type="text/javascript">

how can I let the function that should check the message of the response know that 'msg' has been set?

JQuery :: Loading Image While Fetching Data?

Aug 11, 2010

Apologies if this is a fairly simple question! I'm fetching data (from a MySQL database), and would like to show an animated loading image while the data is being downloaded, and obviously then hide it when the data is fully downloaded. I've found plenty of tutorials describing how to achieve this is the other direction (i.e. when submitting a form) but I'm not sure how to adapt these to what I want.

Stops Working When Fetching Data From MySQL?

Aug 3, 2011

I have my doubts if this question belongs to the javascript side since it's all good until the data from MySQL comes in, but since the javascript is the one breaking I'll take my chances.

The external js (portada.js)

Code:
$(document).ready(function(){
var currentPosition = 0;
var currentPosition2 = 0;
var currentPosition3 = 0;

[Code]....

As you can see I have three divs with different slideshows (slideshow, slideshow2 and slideshow3), they have products that slide to the left. When I was testing to make sure it all looks good the sliding feature was working fine, but I lost this feature when the data was being retrieved from MySQL (at the moment on <div class="slide">).

JQuery :: Fetching Data From Another File And Use It For Changing The "img Src"?

Nov 10, 2011

I already know that i can change the src of an image-tag with jquery / javascript.BUT my problem is, that I try to load the new src-information from a dynamic html-sheet.So every 1 second the image src should be refreshed.

Some of my code:

<script src="jquery.js"></script>
<script>
var auto_refresh = setInterval(

[code]....

You can see in line 17 that it is no problem to show the fetched data from the other html-file in a div every 1 second.But I would like to change a picture dynamically.That means in detail:in the other html file stands either the value "0" or the value "1".This value should be fetched every 1 second (like the div-refresh) from the file.Then the value should be used as new src-name for the refreshing image, e.g.:fetched value = "1" => img src = "1.jpg" => [user can see a green light]fetched value = "0" => img src = "0.jpg" => [user can see a red light]How can I achieve this?

- How can I change the src name

- How can I refresh the image every 1 second with the new src name?

JQuery :: Load Html And Loop Through Json While Changing Html With Json Data?

Sep 11, 2010

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);
});

Compare Incoming JSON Data To The Existing Data?

Sep 9, 2011

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

Send Json As Ajax Request To Server

Aug 14, 2007

whats the best way to pass a json string to the server.

if my jsonstring = {a:&#391;',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

JQuery :: Passing JSON To Server For Ajax File Download?

Jun 14, 2011

I have this code:

var dataString = $.toJSON(data);
$.post(url, {dataValues: dataString}, function(res){
$('#secretIFrame').attr('src', url);
$('#secretIFrame').html(res);
});

Problem is, I can't access dataValues at the server side once I assign this same URL to the iframe.Is there any other way to POST JSON value through form submission without ajax? or any other way out, I am trying to download file that is based on some parameters and isn't a direct download link.

I am doing a password reset form using Jquery and PHP. If I try to submit an email id it should sent and email and report back the response text as success so that the user knows email has been sent. But I am stuck with JSON submit as I have an empty array to decode at the serverside. I am using minified version of json2.js from the official json.org website

Here is the code.
Code JavaScript:
var formdata = $("#log-box").serializeArray();
formdata = JSON.stringify(formdata);
var notifymsg;
alert(formdata);
$.ajax({
type: "POST",
url: "forgot-pass.php",
contentType: 'application/json',
data: formdata,
success: function(responsedata){
var some = responsedata.split("&");
$.each(some, function(index,value){
//alert("index="+index+"value="+value);
});
},
error: function(o, s, e){
alert("Form not posted
"+e);
}});
formdata alerted gives:
[{"name":"email","value":"ravi.k@gmail.com"},{"name":"acctype","value":"loginaccount"}]

PHP forgot-pass.php
Code PHP:
print_r($_POST);
Gives
Array(

AJAX :: Request + Pass Json Objects To The Server? - Firefox Error: No Element Found

Feb 8, 2010

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?

JQuery :: Getting Data From JSON File?

May 4, 2010

I think I have a varialbe scope problem here, but I can't figure it out. What I'm trying to do is extract a piece of data from a JSON file using a variable established earlier in the script as one of the keys.

When I run this script I get the alert that lets me know that the variable "theMappableItem" has been established correctly. I click "OK" in the alert box. Then in my console (in firebug) I see a line showing that the .json file has been gotten successfully. Next in the console is an error that says:
