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.

JQuery :: Create Copy Of File On Server Change It And Create Download Link On Page?

Dec 16, 2011

I have files on the server: .txt, .xml, .config, and "no extension" - all editable with notepad.

User will write some input, it will be added to file in specific place.

I need an ability to change element value in file (in one of them - depends what user choose) (or it even can be some trigger word it-self like CHANGE_ME for not to use attributes)

Create a temporary copy of edited file and create a unique temporary link to it.

I don't know what to start from.... For now I know how to make XHR, but what to do with other extensions?

Have no idea how to save the NEW file (a copy of original file) on server , and create a UNIQUE link ,and delete the file right after it was downloaded.

I can find a specific word in xml file, but how to change it?[code]...

JQuery :: Form Malsup - IE7 "File Download - Security Warning" On Ajax File Upload ?

Dec 15, 2010

I implemented Malsups jquery form and use it for ajax file uploads. Works fine in FF, but in IE as soon as the ajax has completed the upload IE gives me a File Download box - Security warning. If I click on save it save thereturnedJson object (I do JS call onsuccessto get a file list and display it). If I click cancel or save on the popup has same effect the file still gets uploaded but just looks ugly.

How can I get rid of this? All coming form the same domain, calling from the same domain. This is on a python django project and I am testing it on the dev server.

Its pretty basic jquery nothing to exciting, don't get why IE would cause.

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: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

JQuery :: Get Json File With Ajax?

Jun 1, 2010

How can I get the json that this url generates?[URL]... It returns a json object as a file to download, I've tried getting the data as jsonp, but it needs a callback in the feed, but I can't generate it cause the server which generates the code is external.

[Code]...

Couldnt make it work using the get method. And using other data type just would make the incoming data as null (even including ?callback=? in the url).

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 :: Json Considered The Better File Format For Loading Data Via AJAX?

Aug 14, 2011

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?

Ajax :: Modification - Function To Load Text File Information From The Server

Sep 24, 2011

I have been successfully using the following "myAjax" function to load text file information from the server.

ajax.js:

After I load the text file, I store the text "records" into an array by doing something like this:

Where the '}' character is my record delimiter. It could just as easily be ' ' or ' ' or the like.

Again, I am not having any problems doing it this way as it suits my current needs.

Now the question(s)

1. Does the call to read the text data from the external file always read in the entire contents or can I read one line or delimited record at a time and store it to the array directly without the text storage?

2. If the text is always read completely (my suspicion), can I safely delete the "TextInformation" after I convert to the array format? Is there any memory penalty for doing it this way as the text information can be somewhat lengthly and I don't like the idea of having doubled memory usage when I only need the information in array format anyway?

This is the idea I am considering, but I don't know if there are drawback to this method of if there is a better way to accomplish the task.

ajax.js:

AJAX :: Passing Values As Array To Php File?

Aug 9, 2011

Over in this thread, someone suggested a solution to an issue I was having when attempting to send multiple values per select box to a php file. You can review my original post here for reference:

[URL]

The problem is, when I change my form names to be arrays (i.e. age[] vs. age), it broke my Ajax script. I copied the original script from w3schools, and I don't really know much about javascript/Ajax to know what it is that I need to do to fix this.

Here is my Ajax script:

Code:

<script type="text/javascript">
function showResult(name,age,gender,ethnicity,facility)
{
if (name=="" && age=="" && gender=="" && ethnicity=="" && facility=="")

[Code]....

Now, when I leave my field names without the [], the script works MAHvalously. However, as soon as I add in the [] to the field names, and also update the vars to be age[].value instead of age.value, etc, it breaks.

Javascript To Find Fastest Download Site/server??

Nov 2, 2001

Is it possible, using client-side JavaScript, to test a series of download sites to see which is most likely to be the fastest file download site for a user?

I wondered whether JavaScript could download a portion of a file, or alternatively a small sample image file, just to test the download speed of each site, then report to the user the fastest, next fastest, and so on.

JQuery :: Download File In Background?

Jul 16, 2010

Is there a way to get jQuery to download a js file in the background without parsing it? I have a CMS with a login form, which may take the user 3-5 seconds to fill in the data. I am thinking that if I can pre-load my js scripts which are used after the login page, then this will make things quicker after they login. Can this, and should this, be done?

XMLHttpRequest: Script Works To Request XML File On Server But Not On External Server

Oct 2, 2010

I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page.

The script works fine when the requested XML file is stored on the same server as the script.

The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers?

Javascript Code

window.onload = initAll;
var xhr = false;
function initAll() {
document.getElementById("makeTextRequest").onclick = getNewFile;

data: formdata,
success: function(responsedata){
var some = responsedata.split("&");
$.each(some, function(index,value){
//alert("index="+index+"value="+value);
});
},
error: function(o, s, e){
