JQuery :: Classic ASP And JSONP Output - Return Data
Jun 25, 2011
I found this post: [URL] It explains exactly what I want to do. The person who had the problem seemed to have sorted it out but as my knowledge is not to great I am not to sure what he is getting at. I tried various things but to no avail. All I want to do is return data to a calling javascript using type get and datatype jsonp. If I simply Response.Write "[(""id"": ""123""}]" then nothing happens. So whatever the thread I revered to above is doing it seems to be going in the right direction.
I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?
Relatively new to jQuery but have a problem with getting data to display.Using a webform with 2 forms. User slects and inputs data into the first form, clicks a button then using jQuery .ajax submits the serialized data to a php script. The script processes the input into multiple paragraphs of text which is based on the input from the first form.The data is returned to the webpage and displayed in a text area (of the 2nd form) where the user can edit it to fine tune the wording. The 2 forms are displayed in different tabs so it is easy to move back and forward between the 2 forms.
The problem occurs when the user goes back to the first form and enters or selects different text and then click the submit button to generate a whole new text for insertion into the textarea on the second form. For certain fields the modified text is displayed.However if the whole of the text in the textarea is deleted, then the user clicks the submit button to re-generate the text content area then nothing at all is ever interted into the textarea. If have user alert to check that data is returned from the php handler and this text is correct. BUT when I click on the tab to see the textarea (id is "draftrec") there is no text inserted. The relevant function is below and the line that should insert the text into the textarea is:
I am writing a small data entry screen that will post the form data to a page and return a message. But i cannot get the Success or Error functions working properly.
Here's the code where strData is the posted querystring of:
I'm not sure whether it should be in a form and using the onsubmit or click of a button.
I've got an ajax call that runs a password verification. The username/password work fine but I can't get the php to send data to to the AJAX, instead it just echoe's the result in an alert box code...
I have my code php like that: <?php //Get the data from system and return in EU format function ShowDate() { $Date = date("d"."/"."m"."/"."Y"); return $Date; } //Get the time from system function ShowTime() { $Time = date("H".":"."i"); return $Time; } ?>
Now I have two input box <html> <head> </head> <body> Type the date:<input name="txtdate" type="text" class="input" id="txtdate" title="e.g dd/mm/yyyy" value="<?php echo ShowDate(); ?>" size="9" maxlength="10"> <br> Type the time:<input name="txttime" type="text" id="txttime" value="<?php echo ShowTime(); ?>" size="5" maxlength="5"> <br> London: Friday May 21 2010 05:12:00 <br> New York: Friday May 21 2010 00:12:00<br> Hong Kong: Friday May 21 2010 12:12:00<br> Tokyo: Friday May 21 2010 13:12:00<br> </body> </html>
So.... the important is the user can interactive with the date. If I change the date or time all this values will be change as well. Someone knows how can I do this? The field txtdate I will get from a calendar plugin (javascript) that I already put in my code.
I'm using jquery to pass trough data to another page where I want to insert and delete a record. But the problem is that jquery only inserts or deletes the records and not both together. I use following code: For jquery: $(document).ready(function(){ $("#btnAddPayment").click(payment); }); //example 1 function payment(){ $.ajax({ type:"POST", url: "acceptPaymentExecute.asp", dataType: "application/x-www-form-urlencoded", .....
objRS = objConn.execute(strInsertPayment) objRS = objConn.execute(strDeleteMemberPayment) objRS.close() set objRS = nothing objConn.close() set objConn = nothing The queries work but not together. If I comment the insert statement, my page executes the delete statement. I already tried to call another object for my delete statement but it does the same.
So I'm currently working on a ASP.NET Webforms site and I've run in to a small problem. On my .cs file I have the following Webmethod
[WebMethod] public static string IsJobEditable(int jobid){ try{ string isEditable = "false"; JobsBLL jbl = new JobsBLL(); int jobStatusId = jbl.GetJobStatusId(jobid); //If the jobs is either waiting or being edited it is okay to edit it if(jobStatusId == Convert.ToInt32(ConstantsUtil.JobStatus.Waiting) || jobStatusId == Convert.ToInt32(ConstantsUtil.JobStatus.Edit)){ isEditable = "true"; }return isEditable; }catch (Exception ex){ throw ex; }}
This function in this case will ALWAYS return TRUE as a string. On Aspx page I have the following $(function () { $.ajax({ type: "POST", url: "Coordination.aspx/IsJobEditable", data: "{jobid:" + jobid + "}", contentType: "application/json; charset=utf-8", dataType: "text", success: function (result) { alert(result);
//This is written out in the alert {"d":"true"} I want this in a variable as a string so I can do a check on it before I do some other actions. The format is not a String so I cannot split on it to retrieve the "true" part. }, error: function (err, result) { alert(err); } });});
As you can see in the comments the value I get back in the Callback method is in to me a weird format. The type is unknown and I need this value to be able to proceed with my entire method surrounding the small portion of the Javascript. Where to access the result variable / data as a var or anything else that will let me put it into a var (as a string).
Not sure if this is the correct forum as it covers data retrieved from mysql in a .js file...
I need to grab the last 5 rows from my database (2 fields per row) and list all 5 in a table but from within a .js file that I can externally link to.
I can manage the php / mysql and the output to a .php page but how can this be contained within a .js file?
I believe it is possible but after 2 days of searching on google I'm appealing for assistance.
I realise this could be done with a php include or iframe but that isn't an option and the only way available to import this data is via an external javascript script.
I have an application that is using Classic ASP, SQL server and cookies. But unless the user goes all the way through the application and the details are removed, they stay in the database.
How can I detect when they close the browser or move away to another web url. I have several pages in my app, so I dont want any unload event firing when I change pages.
Only when I move to another website completely or close the browser.
All the code I've seen on the net so far will fire if i change url's. Oh and I need to be able to access the Session's data in order to remove it from the database.
I stumbled on this problem while testing StatusNet for our next release; we use jquery.form's .ajaxForm() to do various AJAX form submissions, including the primary message-sending form which includes a file upload control.
We've not seen problems before, but since upgrading from an old Form plugin version 2.17 to 2.49 a couple months ago, I've noticed our development branch no longer works properly in Opera: the actual submission goes fine, but we're unable to access the XML return data (which usually contains HTML fragments to put back into the UI).
I have a test case which demonstrates this at [URL] (source of the main page & submit handler are included there), using current jQuery 1.4.4 and jquery.form 2.52.
Under Firefox 4.0b10 and other browsers, the forms submit correctly, and we can read nodes and text out of the returned XML just fine.
But on Opera 11.00 and 10.63, the submission goes through but we get back an HTML document containing only "<head></head><body></body>". On Opera 9.63, it also includes the text "Blank page."
I tried to trace this down in jquery.form's history, and the trouble seems to have started around 2.39 with a commit ironically titled "iframe load fix (mostly for Opera)", which changes the event handling for forms submitted via iframe: from that version on, a 'load' event handler is added directly as an onload attribute on the iframe's source, whereas previously it was added with attachEvent or addEventListener.
It looks to me like the iframe is throwing a load event for the "about:blank" page, instead of for the submission.
I can revert back to 2.17 or another working version for now, but I'd like to make sure this is fixed upstream;
I'm very new to jQuery, only picked it up yesterday, so there is very little I understand at the moment. I have a website on which I would like to display a real time, time-series chart displaying results from a database that is constantly updated. how to pull live data from my database and display it in an alert box on my sight. One of the replies said I should use jquery to achieve this.
I am trying to build a webpage quotation form that collects the relevant data then outputs the calculated quote details to a table for an assignment. I know how to build the form and the table so they can be filled filled but i am stuck big time trying to work out best way to output the data on to the table and hide the original form in the process.
Read the first reply below first/instead, it's probably more helpful than this one
There's a lot of talk about AJAX these days and it seems to me it's turning into a hammer for a lot of problems that aren't really nails. If you want your pages to call home but don't want to have to deal with XML parsing and extremely spotty browser support, here's a very simple way to effect communication from Javascript to the server. The server can only (easily) communicate back on the next page hit with this method, but as a one way conduit from client to server post page rendering it can hardly be beat.
I've set it up with a really simple case that keeps track of the total time each user spends looking at a page in ten second increments. I have, for clarity (I hope) stuck it all in one PHP file, but it'll work the same with any server side language:
<?php // this block isn't really too well coded or useful, it's intended more as a simple proof of concept if (isset($_GET['ip']) && ip2long($_GET['ip']) !== false) { // if there's a GET variable (this.php?ip=something) and it appears to be a valid ip... $fname = sha1($_GET['ip']) . '.time' if (file_exists($fname) && strpos(($pre = file_get_contents($fname)), '=')) { // if we have a file and it looks like it might be in the right format, increment the value contained therein list($ip, $time) = explode('=', $pre); file_put_contents($fname, $ip . '=' . ($time + 10)); } else { // else just write it in and hope for the best file_put_contents($fname, $_GET['ip'] . '=10'); } /* //actually returning an image here can help get the loading message out of browser's status bars
header('Content-type: image/gif'); fpassthru('small.gif'); */ } else { ?> <html> <body onload="javascript:setTimeout('serverTick();', 10000);"> <script language="javascript"> var ip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>' // give the javascript an ip or a hash or something to pass back that will be reasonably unique
function serverTick() { setTimeout('serverTick();', 10000); // call this function again in 10 seconds var notshown = new Image(); notshown.src = '<?php echo $_SERVER['PHP_SELF']; ?>?ip=' + ip; // calls this file in attempt to preload an image, instead triggering the above block of PHP } </script> </body> </html> <?php } ?>
This will work in far more browsers than AJAX will, and it's not subject to any domain restriction, it can post to another server without generating security exceptions. It may be possible to get data back in the body of the image and it's definitely possible to get data back coded as image dimensions, if you want to push this method a little further.
Currently I was able to load remote JSON (php) file using JSONP protocol. However, how to do if my remote file is static? In the doc, it said: you can load JSON data located on another domain if you specify a JSONP callback, which can be done like so: "myurl?callback=?". But since my remote file is a static text file, how can I specify the callback in the output dynamically? In fact, I also wonder if it is possible to control the random callback name by modifying jquery source code...
I'm trying to use $.ajax to make a JSONP call, but the callback function is never executed.I have debugging code in my server that acknowledges that a request is received, but that never runs.The same URL works fine if I paste it into the address bar of my browser.
Im trying to figure out if a public picasaweb userid exists or not. Its a pure client app, so no server-side proxies. The 1st method works only on FF & Chrome.
I am building a library of functions which call this function, so I cannot have the data processing done within the success function, I need to extract the data itself.
I am trying to develop a iGoogle-like dashboard that uses JSONP to get the content of each widget from other (trusted) sites.Each widget is a div that will take care of getting its content using $.ajax() and use the callback to update the div with the html content returned with JSONP.The problem I have happens only in Firefox (I'm using 3.6.3):when a site is unavailable or takes longer to return the JSONP content for a widget, it seems that the callback for the other widget does not get executed. All the widgets stay in the "loading" state although I'm sure they have all received the answer.What's puzzling is that if I hit the "stop" button of Firefox, the content of the other widgets get displayed (ie. their displaying callbacks get executed).
If the calls are asynchronous, what prevents Firefox from executing the callbacks for the other widgets once the response is received?Do you have any idea of what's happening and if there's some way around this?
I have some jQuery making ajax requests that works just fine if the server returns a 200 but whenever it returns any error HTTP status none of the events fire. It's happening on more than one request to different servers but I'll just include one example for now:
The request gets made just fine, I can see the response in the net console in firebug and it returns the data I want with a 500 when I do not complete the form correctly. However, it does not fire either the error or the complete function when I get this status, and the ajaxResponse.responseText is undefined when it is logged to the screen. When the form is completed and the request is successfull the success function fires just fine.
