I have an html form that I'd like to be able to edit.When I access the form I'd like for the "old" data to be displayed. I can read data into a php array and echo onto the form, but I'd like to use JSON.I use JSON other places in the app, but always read into a div.I use JQuery for the app.
On a page, I have a javascript json output that is generated through PHP. So, for instance, it would look like this:
Code: var upny_iniresults = { // "q_id" : "65977", // "q_txt" : "What is your favorite genre of Music?", "q_cdata" : [
And then PHP code that generates the JSON. I loop through a question, scan for the results (survey site) and display it as json data. Works perfectly. Basically, the JSON is important because I have existing functions that work with that data (display survey results of that question/etc)Here's the question.How can I generate the same Json output, so it can be read by my other jquery functions (Created by a previous developer, I am a PHP guy) by using Jquery POST as well as a query string. The idea is something like:
Code: $.post("create_json_results_for_this_question.php", $("#firstform").serialize()); # Firstform is the name of the form that is submitted.
So, would a jquery POST allow the JSON to load in my browser (which I will activate during a click function) just as my PHP json output works or is there another way? I just want to simulate the same effect, but be able to USE the jquery querystring that I have, which is:
$("#firstform").serialize());
because this lets me return survey results of a previously submitted question.My last q. was too convoluted and I realized my dilemma is just the json output.
The below code posts a couple of vars to a php file which sends back a json object containing (in the test case) one object called 'faves' with 2 variables (let's say called var1 and var2). I can't seem to access the variables after the ajax call. The result is always an 'undefined' error message. I've tried:
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 have a php-loop to read an xml file (id and comment). Now to my question, must i write the Script into the loop or can i assign via a parameter (or whatever) in the header Script?
Im trying to validate a form (easy) and POST it to a third party WCF service. I am able to validate and POST data to the service, but its returned data (in table format) keeps opening in a blank page with their url in the browser address bar. Can't have that, I need to grab the returned data and .append it to a div on my page. Here is what I have that FAILS
<script type="text/javascript"> $(document).click(function() { //cancel form
I use $.getJSON for all my ajax stuff and it works beautifully but there is one particular situation where I use an iframe hack to do an ajax file upload and even though the returned value is a json object (created with PHP), jQuery treats it like a string. I'm using json2.js right now and it does the trick but I don't like including that much extra code because of one rare situation. So my question is, be it with $.getJSON or by specifying 'json' as the expected return type of an ajax request, jQuery *seems* to be able to convert into json. The string returned is already a json object, I just need jQuery to be able to treat it like one. I've tried wrapping it in a jQuery object but no use. (and I really don't want to go down the eval() path)...
I'm a complete newbie to JSON and I'm trying to make some sense out of itI think that what I want to achieve is fairly basic, but I have no clue where to begin. Here's my problem:I want to get the information from this JSON-string, fetch the value for realm_rank and display it within a header-tag in my html-code.
I'm a beginner in Jquery and I have a big doubt, follow at bellow the code to be better viewed: The method below is static and Static methods do not work with instance, For this reason I passed the 'nameLabel' that the typeis Label by parameter, however I need to catch the exception and show it to the user.
But I'm using Jquery and this method is used in a Ajax Request and I use the Json to pass the datas, how showed below: var idCliente= $("#<%= txtIDCliente.ClientID %>").val(); var nomeLabel = $("#<%= lblMensagem.ClientID %>"); var poligonal = "{ idCliente: " + idCliente + ", + lblMensagem: " + nomeLabel + " }"; But the problem is that I need to pass in my Json the nomeLabel with Label, but always a problem happen, because the same is showed like 'indefined'. How to solve this situation?
I have a string that is like [{"carePacks": [{"businessCode":"J1PS","description":"HP 1"}],"coveragePeriod":12}, {"carePacks":[{"businessCode":"J1PS", "description":"HP s"}],"coveragePeriod":13}]. How to convert it to a json structure and how to get data from the data structure, like get "HP 1".
I have a very simple PHP script that returns JSON like this: {"question":"What day is it?"}
And I'm trying to call it from another page using Ajax. My code looks like this: var url = "/test.php"; $.get(url, function(data){ $.each(data, function(i, value) { alert(value); }, "json" ); });
When I run it I get each character printed out one at a time in a separate alert. And then when I used this line of code: alert(typeof data); It tells me that 'data' is a string. Shouldn't it be a JSON object?
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.
I'm trying to parse a Json string received by $.getJSON(). I can receive the string but firebug gives me an "invalid label" error. I think it is because the string is an hash array with a number as first label, but I'm not sure. This is the string:
{"15":{"id":15,"x":0.4589937586135409,"y": 0.8324914620560137,"z":-0.9435707004102728,"rawData":"1256204002860 13 -442866538 18392602 647462767 314 1777206957 -1664784174 "}} and this is the non-working code:
I am using a framework, which returns invalid JSON Strings like:
/* { "myobject" : "test"} */
The error is the comments before and after the json string. This has been invented for security reasons. As the www says returning JSON directly is somehow discouraged because it can be exploited. I am not a security expert at all but would like to go conform with this recommendation. However, now I get this string above with header type "application/json" Can I somehow hook into jQuery and tell it to remove /* */ from the json string by default before parsing the json and breaking it into objects?
I have a basic HTML form with a button that submits the form via jQuery's $.post to a processor. That processor returns the identical form, including any errors below any of the elements e.g. input, textarea, etc. The response also has a new submit button to submit the form once more, however, because I'm retrieving a giant string with HTML elements and because jQuery already loaded, that new submit button doesn't do anything. How can I parse jQuery's response for that button and assign a handler so that when the button is pushed, it submits the form again?
I have to do something that looks an easy task, but I can't do it.I have a page with a div and an id= "livetimings" assigned to it, I want to show a table inside that div and update it every 20 seconds.I have a php script which prints the table and it works, I've tried that script by itself, now I'm trying to call it through an AJAX call in this way [code]inside the <body> tag I've put a setInterval() which starts the getTempi() every 20 seconds and it also works.The not working part is that nothing appears inside the div.I've put some alerts inside the JS code all of them before the req.open pop up, then nothing, so I think the problem is there, but I don't get it.script.php is in the same folder of the html page.The php script has an echo at the end which prints the html code for the table.
I am slowly working through learning/writing a JS project.here is the core issue.:
var pt =<? echo json_encode($prt);?> alert(pt) // for diagnostic purposes
json is flattening the PHP array to be used in the script.However, the alert shows me that I only get {[ ,which is just before the first set of double quotes.JS quits at the double quotes, leaving me with an undefined array.How do I fix this?
