How can I parse the returned data to get a specific element if the returned data is just an html page?
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.
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).
I want to send data to a database by a classic asp page. This page returns xml which I want to parse on the client.

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:
$("textarea#draftrec").html(data).show();
//------------------------------------------------------
$("form#form1").submit(function(e){
[code]....
If I have this:
$.post('/admin/duration', $str, function(data){
var jsonData = eval('(' + data + ')');
return jsonData.TIME;
});
How do I get the return value from the function to use afterwards? I know this must be simple. I'm just not seeing it.
JSON.parse: unexpected end of dataat line var data = JSON.parse(json);Is the syntax correct?the code used is:For the code below i am getting this error :
$(document).ready(function(){ $("#button1").click(function(){
$.post(
'script_1.php',
[code]....
I wonder if i can make the variable data which is [data] in jQuery.post( url, [data], [callback], [type] ) dynamic. for instance, this is the form i want to send,
PHP Code:
<form action="send_xml.php" method="post" enctype="multipart/form-data" id="form_send"><input type="checkbox" id="var_1" class="checkbox"/><input type="checkbox" id="var_2" class="checkbox"/></form>

Is it possible to return Query results from a jquery $.ajax POST call?It seems as though it will only return one value. What am I missing? [code]
View 1 Replies View RelatedI am returning the following to $getJSON() and not getting any results:
{"QC":["x","y","z"],"RM":[{"DEFAULT":"default_project1"},{"DEFAULT2":"default_project2"},{"DEFAULT":"default_project3"}]}
In the "RM" array there are three objects, each a single name/value pair. The name of the array[0] object ("DEFAULT") is identical to the name of the array[2] object. No results are returned by the getJSON call. Since each object is a separate array value, there shouldn't be any object name collision problems. Note that if I change the name of the array[2] object to "DEFAULT3", the data structure is handled properly.
Using the [url]. I am not able to find the documentation on usage of parse option in [url]
How to add details like what goes into data,value and result name/value pairs and when to use it.
I am developing a web application in java (jsp's and servlets). For the project I am working on I will need to develop an html data entry screen and the code to load data into the screen, and then save the data back to the back-end database.
How to do the following:
Read the data out of the database (JDBC, no problem) in a servlet.
Put the data into the appropriate form for returning to the data entry screen, which will be a jsp. (Is JSON the right choice for passing the data from the servlet to the jsp?)
In the jsp, parse the returned data and populate the HTML form elements (text fields and combo boxes). When a button is clicked, pull the data out of the form elements and return to a servlet for saving back in the database.
I'm trying to access data from a .txt file, and parse that data with jQuery. My .txt file is written like this:
&month=November&day=Tuesday&hour=15
If I use jQuery.get() I do see the data but I want to parse through that data so I can get name and value pairs. This is what I used:
<script type="text/javascript">
jQuery.get('http://www.example.com/test.txt', function(data) {
alert(data);
});
Why is it necessary to eval or parse JSON data?If it is legal JS, why couldn't I just name the file in the src attribute of a <script> statement?
View 4 Replies View RelatedI have been struggling with a form wizard all day. I'm using jquery stepy (form wizard) along with validation plugin. To cut a long story short, my first step is to get MySQL connection from form controls details. On submit ('next' button) a check is made on an empty hidden control ('hid').
rules: {
hid: {
required: function(){
return checkDBData();
},
messages: {
hid:
{required: 'SQL not available'},
...(etc)...
So, if the function checkDBData passes, false should be returned, so that the form can progress to the next step. If the connection details fail, true is returned so that an error msg is posted.
Here's the checkDBData function:
function checkDBData(){
var host = $('#mysql_host').val();
var username = $('#username').val();
var password = $('#password').val();
var dbname = $('#dbname').val();
$.post("install/sqlcheck.php",
{"host": host,"username": username, "password": password, "dbname": dbname},
function(msg){
if(msg.required == false){
return false;
}else{
return true;
}},
"json"
);
}
The return values don't find their way back to the rules. However, if I hard code false and true to the function...
function checkDBData(){
var host = $('#mysql_host').val();
var username = $('#username').val();
var password = $('#password').val();
var dbname = $('#dbname').val();
$.post("install/sqlcheck.php",
{"host": host,"username": username, "password": password, "dbname": dbname},
function(msg){
if(msg.required == false){
return false;
}else{
return true;
}},
"json"
);
return false; //or return true for testing purposes
}
This works. I assume it's due to the asynchronous nature of the ajax call.
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...
View 2 Replies View RelatedBefore 1.4, it is possible to return an unique ID with jQuery.data(elem), now seems does not work.

The new api must need a key, what is the key then?
I just want an unique ID by inputing an element, why I need such a key?
I am trying to make an ajax POST request but its not working. Code below:
var _HOMEDIR = "http://localhost/personal/index.php/home/";
$(document).ready(function() {
$("form").submit(function() {
var str = $("form").serialize();
[Code]....
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.

<?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>

<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">

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.
Does anyone know where I can find an ASP server side script written in
JavaScript to parse text fields from a form method='POST' using
enctype='multipart/form-data'? I'd also like it to parse the filename.
<form name='form1' method='POST' enctype='multipart/form-data'
action='sub.asp'>
<input type='text' name='title1' value='value1'>
<input type='file' name='file1'>
</form>
I found a great ASP VBScript for uploading files, but the rest of my
Web site is coded in ASP using JavaScript and I can't figure out a way
to immediately pass the text fields already parsed from server side
VBScript to server side JavaScript.
My ASP code looks like this:
<script language="JavaScript" runat="server">
//I would like to add JavaScript to parse the text field and
filename of file1 here.
</script>
<!--The 3rd party document below parses all fields from the message
content and uploads any file fields it encounters.--->
<!--#include file="aspinclude/upload.asp"-->
<script language="JavaScript" runat="server">
//Add record here (title1, filename from file1).
</script>
I'm a total JS/jQuery newbie, and I'm having a problem using jQuery's load() to POST data to a remote PHP script and rewrite a DIV with whatever the server sent back.
Using a proxy in between, I can see that the JS script isn't sending anything, so I guess there's something wrong in the JS code I send to the browser [code]...

I have some radio buttons and do a jquery post on click. Something like this: $.post("method", { value: value }, function(data) { alert(data); }); the value data does have the correct result, but my problem is the page doesn't refresh to that data.
View 2 Replies View RelatedI am new to all this but making good progress and having fun in the process. I have written quite a bit over recent weeks (including a few $.post / $.ajax calls) for various sites/applications but this one is really puzzling me. Here is a snippet of code that is causing me problems.
[Code]....
The problem is that execution jumps from line 2 to line 6 ... ignoring the function(data) and I am not sure why. I get the correct value of "team" arriving at the perl script .... and the perl writes the correct json back. I just can't think where else I need to look to debug this - as I said, I have done something similar 5-6 times over the last few weeks - all without a problem. So I am sure I am doing something stupid here.
I want to POST data to my personal website[code]...
If i run the code from my localhost it doesn't return anything
