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?
View 2 RepliesI have a JSON data structure that I'm pulling in VIA an AJAX call. What I want to be able to do is click a button/link and be able to save this data structure to disk, but I'm not really sure how to go about this. I've been experimenting with the following:The link has the following format "<a href='data:application/json, " + data_structure + "'>Click here!</a>" I've been able to replace data_structure with text and /json to /rtf, which gives me a pop-up 'SaveAs' dialog box, and when I open the file, it has my text in there. However, if I do data_structure, I just get [Objectobject], which is telling me that I'm passing in the object, but that's basically it, I need to expand it out? I'm not really sure how to do that...Which leads me to calling a perl script. So I make an ajax call like so:
$.ajax({
'dataType': 'JSON',
'type': 'GET',
[code]....
I think I have a varialbe scope problem here, but I can't figure it out. What I'm trying to do is extract a piece of data from a JSON file using a variable established earlier in the script as one of the keys.
When I run this script I get the alert that lets me know that the variable "theMappableItem" has been established correctly. I click "OK" in the alert box. Then in my console (in firebug) I see a line showing that the .json file has been gotten successfully. Next in the console is an error that says:
[Code]...
I have a form that asynchronously submits to a PHP file. The PHP file returns the following:
PHP Code:
echo json_encode($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>");
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?
View 2 Replies View RelatedI 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:
<div class="details"><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span><span class="main-armory button"></span></div>
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.
well i'm kind of new to this website and scripting with javascript but i am wondering: in a client side .js file i have some coding which results in a string which is stored in a variable called exportData
now i want that string to be written into a text file on a server but how do i do that? it is not local on the client's pc and i can't find how to do it anywhere..
how to load an XML file into a DOM. I can get it done in IE, but in mozilla I am missing something. Here is what my loadXML() function looks like:
function loadXML(){
try {
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.onreadystatechange = verify;
hasFile = xmlDoc.load(info.XMLDocument);
if (hasFile){
xmlObj = xmlDoc.documentElement;
allTopics = xmlObj.getElementsByTagName("topic");
}}
catch(e) {
xmlDoc = (new DOMParser()).parseFromString(document.getElementById('info').innerHTML, 'text/xml');
hasFile = true;
allTopics = xmlDoc.getElementsByTagName("topic");
if (hasFile){
allTopics = xmlDoc.getElementsByTagName("topic");
alert(allTopics[0].firstChild.getAttribute("name"));
}}}
Where verify is another function. The try part works for IE, but the catch part doesn't work for Mozilla. I am not finding any information as to really use an XML DOM properly in Mozilla. I'm trying to get allTopics to be a handle on the same thing in both the "try" and the "catch".
is there a way of sending data inputted into a form inside a chunk, to an ASP form on a completely external page (i.e on a different, unrelated site)?This is the code I have for the form chunk:
Code:

I have a JSON structure in API.When I call the API in my code it returns as the same JSON .I have to print this JSON result as table with pagination in Javascript. The table should be dynamic with previous and next buttons and the table should populate the results according to the JSON and each page should have 20 entries and then the remaining entries should go on the next page and I should be able to go back and forth in the table using previous and next respectively.tell me the exact code of how to start with getting JSON from the API and then write the JSON data in the form of dynamic table with pagination.

I have just started to learn about JQuery and wanted to learn how to retrieve data from an API.
I used the Flickr example provided here [url] and just changed the relevant code to point to the 500px api.

If I launch the following URL I do get the results properly [url]
Here's a sample of what the result looks like:-
I don't get any results when I run my code page. What am I doing wrong?
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 working on a project where the jquery/design guru was fired and I am trying to pick up the pieces. Long story short, the project offers surveys to visitors. They click on a submit button (really just a css #id that looks like a button)
Code:
This then loads JSON that is generated via PHP during onload.
A sample of the json:
Code:
I load this json upon page load but I have a problem. On the home page, we have many questions and the json needs to be loaded with a MYSQL query (as of now) such as Select choices from questions where ID = 'question_id'
Here's my dilema. Upon button submit, the json is loaded through a function that animates. It works perfectly, but since I cannot pass the question id to the PHP script that creates the MYSQL query, I can't DYNAMICALLY load the JSON after a vote, only the data BEFORE a vote
I try to load it through an external PHP page but it never loads. For instance:
Code:
So I am able to vote upon submission of 'button' upny_sresbtn1 That works just fine. The problem is the JSON of /return_results.php DOES NOT LOAD. Only the json that loads upon onload, not the return_results.php + formData loads. Oddly enough, when I use the same function, above, with another submit form (one with a form and a bunch of select options, it loads the json from return_results properly) :/
It's supposed to load this function (upny_loadRJSON)
Code:
See the bold part? That's the animate function, which is:
Code:
The part that displays the results, before animation, is below:
Code:
The dilema is upny_iniresults.q_cdata is the json loaded upon first visit to the site. I am trying to get it to read the res_json JSON output from the return_results.php which is posted to upon submission. THAT never works. Instead, only the onloaded json loads. The process, from animation/etc DOES work just not for the JSON data I want.
I'm new to js/jquery and this forum so please forgive my potentially off-scope js/jquery remarks. I've been running a lot of toggles to show, hide, etc... divs and other HTML elements. It's making my application incredibly nice navigation wise.
Now to put myself in my users shoes. Say one user toggles on and off the things they want and don't want until they are satisfied with all the content of the screen. (That is by the way the nature of my application. A user loads in various variables via PHP and other means and when satisfied, a PDF is generated for them containing all their preferred content.)
Because: When a user is at a point where all the content they are viewing is worthy of a PDF, it is also worth saving that HTML 'view' (classes switched, variable adjusted, etc...). I would call it 'Save this workspace' or something along those lines.
I don't have a direct question per se but am more interested in the views of others who have similar thoughts and moreover, what relationship has jQuery had in helping employing some method?
I tried to pass the external JSON object on validate method. But It's not working.
Here is my sample code:
I wrote a script to generate links to some pictures that I need to
regularly update our site with. Is there a way to write a script that
just saves the pics to a directory on my pc so I dont have to right
click on every link and do a save picture as...? I can't link
directly to the pics from our site because our site is https and the
site the pics are on are http so the user gets the security warning
box every time a pic loads. Code:
I would like to code a couple of scripts for saving various data into cookies, and then post them to e-mail through a cgi script. To be more clear, I want to save some questionare's answers given through a series of html pages, to cookies. When (and if) the last question is answered, send all the answers to an e-mail address.
View 8 Replies View RelatedI've been working on my code for some time but I know I'm missing the ability to save the completed time card entry to a file. Can someone assist me with the scripting code for this.I would like the user to be able to specify the location. I have search the forum and I have not found any question like this which surprises me. Please forgive me if I have posted in the wrong area.Currently I have no Java Script code to show for this part of my project because I'm completely stuck. But I have my unfinished XML code that is not pretty because I plan on using a style sheet to enhance. But here is the code for you to get and Idea of what i'm attempting.
Code:
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html
[code]....
//-----10% Off Coupon-----
if (coupon=="N110"){
form.PRICE.value=-(moneyFormat(fTotal * .10)-1);
form.ID_NUM.value="N110";
form.NAME.value=" Craft Month Promo 10% Off";
location.href=location.href;
return true;
}
I want to replace the .10 with an external peice of data, so users can change the amount with having to open the script. Sorta like those early marquees' where the marquee text was inserted from a text file.
im working on a web application that generates dynamic data. My question is: i want users to be able to save the generated data, but not the whole web page, just a table in the web page that holds this data. I searched and found out that showing a "save as" dialog box is possible with javascript, with a method like: onclick="javascript: document.execCommand('SaveAs',Ƈ',null);. However, i coulnd't find out how to change the document object (or is it possible?) or a trick to print just the table of dynamic data.
I tried to cover the table with <div id="myData"></div> and use onclick="javascript: myData.execCommand('SaveAs',Ƈ',null); but as you might guess, it didn't work and gave this error message: "object doent support this property or method". Indeed i dont have any idea what div tag can and can't do, so it was just a meaningless try. By the way, i want to add that i can't use iframes just because of program design issues.
Anyway, do you have any suggestions?
I am working on a project in which I will have to generate a .html file and save it to the user's hard drive.
View 5 Replies View RelatedI'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"}]

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
I have an ASP page that displays, along with other data, a list of items that refer to a specific element in a database. Instead of adding an Add button, I would like to display a text box below the last item in the list to have the user input any new data. Once they enter the data and hit Enter, the data they enter should then be added to the list and another text box added beneath this item (just as forms and tables in Access do). However, I'm not sure how to implement this functionality.
