EDIT2: I'm trying to update my code with java, but it's not working (I suppose I miss something in controller):
$(document).ready(function() {
var listGraphic = new Array();
function addPhoto(u, d) {
$.ajax({
url: "aggiungiEpigrafe",
type: "POST",
data: {"graphicUrl": u, "graphicDesc": d},
success: function(data) {
var $url = $("<form:input>").attr({
path: "graphicUrl",
disabled: true
}).html(u);
var $desc = $("<form:input>").attr({
path: "graphicDesc",
disabled: true
}).html(d);
$("#listGraphic").append($url, "<br />", $desc, "<br /><br />");
$(this).dialog("close");
},
error: function(xhr, textStatus, error){
console.log(xhr.statusText);
console.log(textStatus);
console.log(error);
}
});
}
$("button#insertFoto").button().click(function() {
$('#insertPhoto').dialog("open");
return false;
});
$("#newPhoto").submit(function(e) {
e.preventDefault();
var url = $("#graphicUrl").val();
var desc = $("#graphicDesc").val();
listGraphic.push(url);
listGraphic.push(desc);
console.log(listGraphic);
addPhoto(url, desc);
$("#graphicUrl").val("");
$("#graphicDesc").val("");
if ($('#insertPhoto').dialog("isOpen")) {
$('#insertPhoto').dialog("close");
}
});
$('#insertPhoto').dialog({
autoOpen: false,
buttons: {
"Close": function() {
$(this).dialog("close");
},
'Insert': function() {
$("#newPhoto").submit();
}
}
});
});
EDIT1:
Following Twisty suggestion I uptaded the dialog in order to not have any form inside (since this dialog is already in a form): https://jsfiddle.net/e57sj6hp/18/
As Twisty was also commenting, I probably need ajax, but I have to understand how use it; I think I need to use serialize() or seralizeArray(), but I don't understand well how should the controller receive the json and use it.
I have a controller like this:
public String myMethod(#ModelAttribute MyObject object, ModelMap model){...}
The object include a List of photos, and two variables url and description:
List<Photo> photos;
String url;
String description;
each photo in the list is formed by an url and a description.
In my jsp I created a dialog with jquery where a user can put an url and a description, what I want to do is to add each value into a list and send it to the controller, then clean the dialog in order to allow another submission.
I have tried a lot of but can't understand how I should do it. I'm using the spring's form and I have tried many different ways, but I think that the problem is in my javascript code. Here's one example: https://jsfiddle.net/e57sj6hp/12/
In this example the input fields and the textarea inside the dialog aren't surrounded with spring's form tags, since I've append the result inside the div and I supposed that, at the moment of the submitting, the controller should receive the data inside the form:input just created.
Not familiar with Spring, so I may miss an element, but matching what you put in your example, I can offer some potential updates.
Working Example: https://jsfiddle.net/Twisty/e57sj6hp/16/
HTML Updated
<div id="insertPhoto" style="display:none" title="Insert a Photo">
<form id="newPhoto">
<label>Url:</label>
<br/>
<input id="graphicUrl" />
<br/> Description:
<br/>
<textarea rows="4" cols="20" id="graphicDesc"></textarea>
</form>
</div>
You cannot call form.reset() without a form element. I wrapped the the form elements in a form. This has the added benefit of now responding to the form being submitted, for example if the user enters a url and hits enter.
jQuery
$(document).ready(function() {
var listGraphic = new Array();
function addPhoto(u, d) {
var $url = $("<form:input>").attr({
path: "graphicUrl",
disabled: true
}).html(u);
var $desc = $("<form:input>").attr({
path: "graphicDesc",
disabled: true
}).html(d);
$("#listGraphic").append($url, "<br />", $desc);
}
$("button#insertFoto").button().click(function() {
$('#insertPhoto').dialog("open");
return false;
});
$("#newPhoto").submit(function(e) {
e.preventDefault();
var url = $("#graphicUrl").val();
var desc = $("#graphicDesc").val();
listGraphic.push(url);
listGraphic.push(desc);
console.log(listGraphic);
addPhoto(url, desc);
$(this)[0].reset();
if ($('#insertPhoto').dialog("isOpen")) {
$('#insertPhoto').dialog("close");
}
});
$('#insertPhoto').dialog({
autoOpen: false,
buttons: {
"Close": function() {
$(this).dialog("close");
},
'Insert': function() {
$("#newPhoto").submit();
}
}
});
});
Lots of little fixes and improvements here. I moved listGraphic out of the functions, so it can be updated more globally. This allows it to be updated and read from other callbacks.
I created the function to make it a little easier to repeat.
Now regardless of how the form is submitted, the array is updated and so is the page. The dialog is closed and it's form is reset.
UPDATE 1
See new jQuery: https://jsfiddle.net/Twisty/e57sj6hp/21/
jQuery
$(document).ready(function() {
function addPhoto(u, d) {
$.ajax({
url: "aggiungiEpigrafe",
type: "POST",
data: JSON.stringify({
"graphicUrl": u,
"graphicDesc": d
}),
complete: function(data) {
var $url = $("<form:input>").attr({
path: "graphicUrl",
disabled: true
}).html(u);
var $desc = $("<form:input>").attr({
path: "graphicDesc",
disabled: true
}).html(d);
$("#listGraphic").append($url, "<br />", $desc, "<br /><br />");
}
});
}
$("button#insertFoto").button().click(function() {
$('#insertPhoto').dialog("open");
return false;
});
$('#insertPhoto').dialog({
autoOpen: false,
buttons: {
"Close": function() {
$(this).dialog("close");
},
'Insert': function() {
addPhoto($("#graphicUrl").val(), $("#graphicDesc").val());
// Reset values
$("#graphicUrl").val("");
$("#graphicDesc").val("");
// Close Dialog
$(this).dialog("close");
}
}
});
});

I tried to create a drop-down menu using options binding in KnockOut JS (ko.plus to be precise). Things were running as expected until I mixed my solution up with this jsfiddle: http://jsfiddle.net/jnuc6y05/ in order to place a default option in the list. The problem lies in "HERE" (please see the code) where I get
error message
"TypeError: this.fieldStreetApallou is not a function"
As I said I had no problem, and I think mixing plain javascript with KO caused the situation. I tried to unwrap the editable with no luck since it resolves to undefined. Even ko.toJS does not do the trick (undefined again).
I don't have any serious experience with KO and furthermore with Javascript, and any help would be greatly appreciated.
PS: Reduced code provided
/////// HTML
<input data-bind="value: fieldStreetApallou, enable: fieldStreetApallou.isEditing" />
Rename
<div data-bind="visible: fieldStreetApallou.isEditing">
Confirm
Cancel
</div>
/////// Javascript
<script type="text/javascript">
ko.observableArray.fn.find = function(prop, data) {
var valueToMatch = data[prop];
return ko.utils.arrayFirst(this(), function(item) {
return item[prop] === valueToMatch;
});
};
var availableCompanies = [{
offset: 1,
name: "Company1"
}, {
offset: 2,
name: "Company2"
}
// ...more pairs here
];
//Default pairs for the drop-down menus
var selectedCompanyApallou = {
offset: 1,
name: "Company1"
};
var ViewModel = function(availableCompanies, selectedCompanyApallou) {
this.availableCompaniesApallou = ko.observableArray(availableCompanies);
this.selectedCompanyApallou = ko.observable(this.availableCompaniesApallou.find("offset", selectedCompanyApallou));
this.fieldStreetApallou = ko.editable("Initial value");
postStreetFieldToServerForApallou = function() {
$.ajax({
type: "PUT",
url: "http://www.san-soft.com/goandwin/addresses/" + 15,
contentType: "application/x-www-form-urlencoded; charset=utf-8",
data: "Address_id=15&Street=" + this.fieldStreetApallou() //<---- HERE!
}).done(function(data) {
alert("Record Updated Successfully " + data.status);
}).fail(function(err) {
alert("Error Occured, Please Reload the Page and Try Again " + err.status);
});
};
};
ko.applyBindings(new ViewModel(availableCompanies, selectedCompanyApallou));
</script>
I think you linked to the wrong JSFiddle.
Looks like this is not what you are expecting when postStreetFieldToServerForApallou is called by the button click. this in JavaScript is based on who called the function.
To work around it in this case, I like to set var self = this; at the top of the view model so self always points to the view model, then I replace all instances of this with self. This is really only needed on your HERE line, but it simplifies to use self throughout.
The fixed view model code:
var ViewModel = function(availableCompanies, selectedCompanyApallou) {
var self = this;
self.availableCompaniesApallou = ko.observableArray(availableCompanies);
self.selectedCompanyApallou = ko.observable(self.availableCompaniesApallou.find("offset", selectedCompanyApallou));
self.fieldStreetApallou = ko.editable("Initial value");
postStreetFieldToServerForApallou = function() {
$.ajax({
type: "PUT",
url: "http://www.san-soft.com/goandwin/addresses/" + 15,
contentType: "application/x-www-form-urlencoded; charset=utf-8",
data: "Address_id=15&Street=" + self.fieldStreetApallou() //<---- HERE!
}).done(function(data) {
alert("Record Updated Successfully " + data.status);
}).fail(function(err) {
alert("Error Occured, Please Reload the Page and Try Again " + err.status);
});
};
};
I'm having an issue with posting data via AJAX through a drag and drop interface. The data indeed is hitting my POST URL as defined, however, each and every time, the POST hits twice thereby causing the processing URL to handle the data again.
The premise of my application (at least this piece of it) was starting by basically using the code found at http://jsfiddle.net/UjQVw/2/ and to modify it for my needs.
I needed to have a container of items (in this case names) that were draggable to a user-defined number of divs on the opposite side of the screen -- whereby making 'room assignments' with a list of people.
Everything, except for the double POST is working well. If anyone can assist, I'd be most appreciative!
SAMPLE HTML CODE:
<div class="parent_list">
<h1>Registrants</h1>
<ul id="unplaced" class="group">
<?
foreach ($obj->function as $key => $value)
{
?>
<li data-group-id="0" data-post-id="<?=$value["rmid"]?>">
<?=$value["lname"]?>, <?=$value["fname"]?>
</li>
<?
}
?>
</ul>
</div>
<div class="lists">
<h1>Rooms</h1>
<ul style="display:none" id="new_list" class="group"></ul>
</div>
<input type="button" id='add' value="+ Add Room"/>
SAMPLE JS
<script>
var count = 0;
$("#add").click(function() {
count++;
var $clone = $("#new_list").clone();
$clone.attr({
id: count,
style: "" // remove "display:none"
});
$clone.find(".group").each(function(){
$(this).attr({
id: $(this).attr("id") + count
});
});
$(".lists").append($clone);
$('.group').sortable({
connectWith: '.group',
update: function(event, ui) {
var lodging = new Array();
$('.group li').each(function(i) {
var id = $(this).attr('data-post-id');
var group = $(this).parent().attr('id');
lodging.push(group+'_'+id);
});
console.log(event);
$.ajax({
type : "POST",
cache : false,
url : 'lodging_process.php',
data: {
'lodging[]': lodging
},
});
}
});
});
</script>
You could always buffer it with a boolean.
<script>
var sending = false; //Buffering variable
var count = 0;
$("#add").click(function() {
count++;
var $clone = $("#new_list").clone();
$clone.attr({
id: count,
style: "" // remove "display:none"
});
$clone.find(".group").each(function(){
$(this).attr({
id: $(this).attr("id") + count
});
});
$(".lists").append($clone);
$('.group').sortable({
connectWith: '.group',
update: function(event, ui) {
var lodging = new Array();
$('.group li').each(function(i) {
var id = $(this).attr('data-post-id');
var group = $(this).parent().attr('id');
lodging.push(group+'_'+id);
});
console.log(event);
if(!sending) { //Make sure we are not already sending a request
sending = true;
$.ajax({
type : "POST",
cache : false,
url : 'lodging_process.php',
data: {
'lodging[]': lodging
},
success: {
sending = false; //Upon finishing, allow another ajax command of this type
},
error: {
sending = false;
}
});
}
}
});
});
</script>
See if that works.
After the response by #John, I did some more testing and looking around and found this gem that's apparently stumped several others by me. As stated in the original question, the POST was indeed working...it was simply posting TWICE after each event. The reason for this is that there were changes in BOTH lists, thereby initiating the callback for EACH list that's affected.
Adding this simple if check as outlined here: https://forum.jquery.com/topic/sortables-update-callback-and-connectwith
update:function(e,ui) {
if (this === ui.item.parent()[0]) {
//your code here
}
}
has done the trick for me. Hope this information helps others with multiple callbacks using jQuery sortable and connectWith functions.
So...the new JS looks like this:
<script>
var count = 0;
$("#add").click(function() {
count++;
var $clone = $("#new_list").clone();
$clone.attr({
id: count,
style: "" // remove "display:none"
});
$clone.find(".group").each(function(){
$(this).attr({
id: $(this).attr("id") + count
});
});
$(".lists").append($clone);
$('.group').sortable({
connectWith: '.group',
update: function(event, ui) {
if (this == ui.item.parent()[0]) {
var lodging = new Array();
$('.group li').each(function(i) {
var id = $(this).attr('data-post-id');
var group = $(this).parent().attr('id');
lodging.push(group+'_'+id);
});
$.ajax({
type : "POST",
cache : false,
url : 'lodging_process.php',
data: {
'lodging[]': lodging
},
});
}
}
});
});
</script>
I have a collapsible part of my jQuery Mobile page that are generated from PHP output from a MS Sql databas and content render as I like it to so that part is ok.
in each section I create a form with 3 buttons and they are supposed to have unique Id:s.
All forms are also created to have a unique id created in runtime.
actions.php (renders out my elements into mobilepage i a DIV)
$counter=0; reset counter for ID:s
while (odbc_fetch_row($rs)){
// data output from Db to make like 10 collapsible with different data
$html = "";
$html = "<div data-role='collapsible-set' data-mini='true'>";
$html.="<div data-role='collapsible' data-mini='true'>";
$html.="<h3><span style=float:left;><img src='../_pic/$image' alt='$imageText' /> ".substr($Time,0,16)." $Area</span><span style='float:right;' class='ui-btn-up-c ui-btn-corner-all' cnt> $data </span></h3>";
$html.="<p>ID: $ID $Id $Status<br />$Status $Description)</p>";
$html.="<form method='post' action=''>";
$html.="<button value='action1' id='action1$counter' data-mini='true' type='Submit'>Take Action1</button>";
$html.="<button value='action2' id='action2$counter' data-mini='true' type='Submit'>Take Action1</button>";
$html.="<button value='action3' id='action3$counter' data-mini='true' type='Submit'>Take Action1</button>";
$html.="<input type='hidden' id='id$counter' name='id' value='$dataName' />";
$html.="</form>";
$html.="</div>";
$html.="</div>";
echo utf8_encode($html);
$counter++; //upcount to make Id:s unique
} //end While
Then I have this function that listens for a button that submit:
$(':submit').live('click', function() {
var button = $(this).val();
if (button == 'action1') {
$.ajax({
url: '../_php/Functions.php',
data: 'button=' + $(this).val()+'&id='+$('#id').val(),
async: true,
beforeSend: function() {
$.mobile.showPageLoadingMsg(true);
},
complete: function() {
$.mobile.hidePageLoadingMsg();
},
error: function (request,error) {
alert('error');
}
});
}
return false;
});
I cant seem to get another id than the first one since i need to make all ID:s unique in my forms and all I do now is to check: &id='+$('#id').val(). what I would like to have done is to link the button pressed-id number to my hidden field id-number so i get the right data out from it. As of now I only get the first form:s id evaluated...
If someone could point me in the right direction how to make that happen i´d be greatful.
functions.php (a switch statement is pre-testing for submit:ed action
function actions1(){
try {
if(isset($_GET['id'])){
do stuff with 'id'
}else{
do other stuff with 'id'
}
} catch(Exception $e) {
show error
}
}
If some part is unclear or if you feel I missed posting somepart - let me know. /thanks
Within event handlers this referes to the element
$(':submit').live('click', function(){
var id= this.id;
var button = $(this).val();
/* traverse within form to set hidden input, no need to worry about using ID's for them*/
$(this).closest('form').find('input[name=id]').val(id);
/* then in ajax */
data: 'button=' +button+'&id='+id,
})
Not full code....I left some of your code out for simplicity
You can use jQuery .attr() function to get an id or any other attribute value of an element.
$(':submit').live('click', function() {
var button = $(this).val();
var id = $(this).attr("id");
if (button == 'action1') {
$.ajax({
url: '../_php/Functions.php',
data: 'button=' + $(this).val()+'&id='+ id,
async: true,
beforeSend: function() {
$.mobile.showPageLoadingMsg(true);
},
complete: function() {
$.mobile.hidePageLoadingMsg();
},
error: function (request,error) {
alert('error');
}
});
}
return false;
});
The solution was to go by attributes name of my hidden input.
var id = $(this).closest("form").find(':hidden').val();
I have a Jquery UI autocomplete code that grabs data from an ajax request, as i grab the data the results are already put in the input box where the autocomplete is attached. my problem is i have a other data along the data that will be posted with the result of the autocomplete.
I had tried to grab all the i need and put it in a single string with delimeters so i can split() it on the client-side. I want to save the other data in a hidden text field

You idea is right, you must use a callback as the source parameter. I've put together an example here:
Demo on jsFiddle
If you read the documentation carefully it says:
The third variation, the callback, provides the most flexibility, and
can be used to connect any data source to Autocomplete. The callback
gets two arguments:
A request object, with a single property called "term", which refers
to the value currently in the text input. For example, when the user
entered "new yo" in a city field, the Autocomplete term will equal
"new yo".
A response callback, which expects a single argument to contain the
data to suggest to the user. This data should be filtered based on the
provided term, and can be in any of the formats described above for
simple local data (String-Array or Object-Array with label/value/both
properties). It's important when providing a custom source callback to
handle errors during the request. You must always call the response
callback even if you encounter an error. This ensures that the widget
always has the correct state.
So here is an example implementation I used in the demo:
$("#autocomplete").autocomplete({
source: function(request, response) {
$.ajax({
url: "/echo/html/", // path to your script
type: "POST", // change if your script looks at query string
data: { // change variables that your script expects
q: request.term
},
success: function(data) {
// this is where the "data" is processed
// for simplicity lets assume that data is a
// comma separated string where first value is
// the other value, rest is autocomplete data
// the data could also be JSON, XML, etc
var values = data.split(",");
$("<div/>").text("Other value: " + values.shift()).appendTo("body");
response(values);
},
error: function() {
response([]); // remember to call response() even if ajax failed
}
});
}
});
You can include a function on select. Within that function you can access the value and the label of the selected item and process as needed:
$('#input_id').autocomplete({
source:"www.example.com/somesuch",
select: function(event, ui){
var value = ui.item.value;
valueArray = value.split('whatever delimiter here');
//do what you will with the values
ui.item.value = ui.item.label; //This ensures only the label is displayed after processing.
}
});
FOUND THE PROBLEM:
Just needed to replace row.replaceWith with row.parent().parent().replaceWith().
I'm trying to update a WebGrid row with JQuery after I've clicked a submit button in a modal dialog, but the updated data just append the last column, not the whole row as I want.
Let's say I want the table to look like this after the update:
ID - Name - Phone number
But with my code it looks like this after the update:
ID - Name - ID - Name - Phone number
as it just replaces the last column with a new table within the last column with the updated data.
I'm getting the correct data as output, but in the wrong place in the row.
Please help! :)

You have set row to $(this) which is your case represents $("#event-edit-btn") ( btw i suggest using classes as identifiers, but it's not a problem ). Later on you replace your actual button with the new <tr> set but what you actually need to do is traverse to the tr parent of that button and replace it.
Change your live handler to:
$("#event-edit-btn").live("click", function () {
var url = $(this).attr('controller');
var row = $(this).closest('tr'); //or use some #id or .class assigned to that element
var id = $(this).attr('objectid');
$("#edit-event-dialog")
.data('id', id)
.data('url', url)
.data('row', row )
.dialog('open');
event.stopPropagation();
return true;
});
