JQuery :: Downloading Application/json File Instead Of Handling It?
Jun 1, 2009
Currently I'm developping an application with RoR and jQuery. Is the first time I try to use this wonderful library so I'm still a little naive Right now I'm having a problem that I have no idea how to solve. Documentation, google, etc have been useless for me in this point (probably because I'm not searching the right terms) So I'm creating an invitation system: simply, a form where you put an email address and when you hit submit it makes an ajax call. The server should answer with some data such 'how many invitations the user have left', possible errors and (if in development enviroment) the url for the invitation (debuggin purposes), everything coded in json.
The problem is that sometimes when sending an invitation firefox pops me up with a download dialog suggesting to save an "application/json" file with all the data that the server processed. My jQuery script should be taking care of handling it and it is not. I have told Rails to render the answer in json format: render :json => message.to_json message is a hash with a format similar to {:error => "There was an error, sorry", :invitations_left => current_user.invitations_left} And I have also specified jQuery the type expected in the return of the call:
I have a feeling that the solution to my problem is stupidly simple, but crawling through Google has provided me with none.
I'm trying to handle the login process on one of my clients' site using the AJAX functionality provided by jQuery.
Here is the $.ajax() call in question:
$.ajax({ "cache": false, "complete": function() {
[Code]....
I have already set the Content-Type header of the response to application/json, which made no difference. I also tried text/html and text/plain, but in these cases Internet Explorer shows the JSON as HTML or plain text in the browser window... *sigh*
Googling also gave me the suggestion to just use text/plain and eval() the response myself, but I remember reading elsewhere that this is pretty unsafe. I am unsure on the specifics on this, though.
When I clicked on the download link on the homepage (for both production and development version), the file opened in the browser (see image) but it didn't download.
I am having a problem with a script that I am writing and I believe it is centered within a piece of jQuery code. I have some code like this (simplified slightly):
actually i am working on a project "random password generator". What basically is to be done in this project is to generate user password for the username randomly he has provided. Then, this password is to be stored in a text file in the following manner
UserName Password ABCD JU12H6 Sdjksj HJudfdsfd
Now my problem is that every time I just try to generate a new password, either a new file is made or the heading is rewritten again and again or if I just try to change the variables true and false, then the username and password headings are not printed. Please help. If someone knows how to do this using if-else method then please tell me, how it can be done? The code is attached.
I have the following code below, and its giving me an error saying: "The system cannot find the file specified". <html> <script language="javascript" type="text/javascript"> function start_ccm(){ var wsh = new ActiveXObject('WScript.Shell'); wsh.exec("C:Program FilesWorkDynamics TechnologiesccmApplicationsccmMercury.exe") }
</script> </head> <body> <input id="Button1" onclick="start_ccm()" type="button" value="START" /> </body> </html> There is nothing wrong with the location, but my best guess are the spaces in the file path.
I've got a pc which will hold some log files, and I want to get them onto my server.Rather than use a combination of batch scripts, ftp, and cron jobs, I thought I'd try using an hta htpertext application on the local machine, to upload the log file. So I'm trying to do a hta file that will upload a specified file via a self-submitting (javascript), then close itself, but I'm having 2 problems:1. Specifying the file name as the value of the file in the form doesn't seem to have any effect. The form comes trhough with a blank field.2. On submitting the form to the server, it opens an IE window to view the returned page (even if it's blank). If I ran the script every 10 minutes or whatever, the screen and memory would soo get full.Here' s the code I'm using:
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).
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:
I have a form that asynchronously submits to a PHP file. The PHP file returns the following: PHP Code: echo json_encode($array);
In my Console, I see the following: Response: {"groupname":"XYZ Group","id":4} How do I display that JSON code through jQuery code?
Here's the jQuery code I have so far: Code: $.post("addgroup.php", { groupname:f.groupname }, function(data){ $("#groups tr:last") .clone(true) .insertAfter("#groups tr:last") .html("<td class='tbldata'>"+ /* Returned JSON data (groupname) */ +"</td><td class='tbldata'> /* Returned JSON data (id) */ </td>");
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.
Scenario:i have a user form, and want to modify user details. all user details are from json file. Prob:how can i modify external json file with its updated user details? or what available function to be used?
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.
How can Iload and parse a json file saved in our remote serverfrom my local machine? I can load and parse the copy I saved in my local machine, but I can notwork with the remote copy. The following is the code I tested:
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?
I am doing a JSON request to get data back from a PHP file. On the return of that data, I am using a for loop to go through the data and post it up using JS. Here is my code:
for (var x = 0; x < data.length; x++) { //create a container for each comment var div = $("<div>").addClass("entry round").appendTo("#characters"); //add author name and comment to container $("<div>").addClass("details").appendTo(div); $("<span>").addClass("main-armory button").appendTo("div.details"); }
Now, what is happening, because there is 10 entries being posted, my JS is looking at the class that is being put together (main-armory button) and making it so that class appends every run through. So, I want one entry for main-armory button and I am getting this:
And then, when it goes down to the next entry, it has 9 spans, and then the next entry has 8 spans, and it continues all the way down. What is going on here that I am missing? I know that I am not clearing a variable properly or something is wrong within my loop.
I'm working on a research project and a research partner has provided me with a massive file with data I need to be able to analyze from his website (which aggregates the data I'm interested in from internet sources). I've tried importing the .JSON file into excel, but it's awkward and figuring out an effective way to delineate the data has proven nearly impossible (for example, using ':' doesn't work because in one of the fields I need to study, colons appear, so mid-data field it gets cut-off). Is there any program, technique, or converter to take the JSON file and organize the data into something resembling a spreadsheet? My ultimate destination/goal: I need to sample the data, but only for a couple variables (or I guess I should say fields as in JSON format/lingo each variable contains a couple fields of interest that I need to compare with similar fields from different variables as well as a number of null values/fields), for my data analysis. I need to get the data into some sort of spreadsheet-type format or something that is visually, if not functionally, similar that would allow me to figure out how many datapoints I have in the relevant categories and to randomly sample them. So, to summarize, is there any way to transform the tree-like json file into something column/row oriented automatically, because the JSON file is 35mb, and there's no way I could organize/extract the data I need by hand?
I need to download and read one *.json file in my javascript. Do you know about some library or the best how to do that? The best would be be if the solution would work in all web-browsers.
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.
i have a Json file which is called/summoned from a jscript file which is in turned called from an html file. So the html calls the jscript and then the script calls the json file.
The problem is that only the text of my json file (the other text displays cool) displays incorrectly spanish characters with accents and stuff. So I dont know how to set the charset of the json file. I dont know if i have to do it in the json file or in the jsprit file i already set the charset of the jscript on my html file like this:
