Requirement is to show dialog box on click of a button.I have created dialog box using jQuery UI. Please find the code here http://jsfiddle.net/M4QM6/32/.
ISsue is i have single function for creating dialog box, how can i show multiple dialog box within same page with each dialog box displaying different data,
When i click on dialog2 button, i need to show a dialog box which has textArea and a submit button.Please suggest.
Below is the sample code:
$(function() {
$("#dialog").dialog({
autoOpen: false,
resizable: true,
width:"750",
height:300,
modal: true,
buttons: {
"Close": function() {
$(this).dialog("close");
}
}
});
});
You could go a couple routes. Since your need for dialog content is pretty specific (textarea control - first dialog pops second dialog - etc), I would hard-code the needed divs on the page. So, make a "#textAreaDialog" div and put the needed controls in it ad set its style to display:none.
Next, modify your function to accept parameters (the name of the div that should be popped, the funciton to execute if "OK" is clicked - and the function to execute if "Cancel" is clicked), so you're not limited to using #dialog for all of your modals and you can finely control what happens when each button is clicked (not always just closing the dialog. Then, set event handlers for the click events of the buttons you need, and call your dialog accordingly.
html:
<input type="button" id="btnPopFirstModal" Value="Open First Modal"/>
<div id="divFirstModal" style="display:none;">
Here is the content for the first modal
</div>
<div id="divSecondModal" style="display:none;">
Here is the content for the second modal
</div>
Javascript functions:
function PopDialog(divToPop, OkFunction, CancelFunction)
{
$("#" + divToPop).dialog({
autoOpen: false,
resizable: true,
width:"750",
height:300,
modal: true,
buttons: {
"Ok": function() {
OkFunction();
$(this).dialog("close");
},
"Cancel": function(){
CancelFunction();
$(this).dialog("close");
}
}
});
});
}
function PopSecondModal(){
PopDialog("divSecondModal", function(){ put code for OK Click here}, function(){put code for Cancel Click here});
}
Javascript event handlers:
$("#btnPopFirstModal").click(function(e){
e.preventDefault();
PopDialog("divFirstModal", PopSecondModal, function(){}); //empty function for cancel, but you can add your own code as needed
return false;
});
Remember, you can expand this as much as you want, adding more event handlers and custom divs to use for more tailored modals. Also, as you can see, you can write your OK and Cancel funcitons inline when calling the PopDialog function - or you can pass it a function name (this is preferable if you're going to reuse that function).
Here is how I did:
$(
//when JQuery is ready
funciton()
{
$('#SomeButton').on
(
'click',
function()
{
//Note that content could be anything (HTML, text...)
//This dynamicly create a div to be your dialog
$('<div>').append(content).dialog
(
{
//autoOpen: false, I removed it you can put it back in if you need it but I dont think its important for now
resizable: true,
//I remove the double quotes here because height didn't have any but maybe it was the other way around
width:750,
height:300,
//I put this on false because if two or more dialog would need to be displayed at the same time you can't have them modals.
modal: false,
buttons:
{
Close: function()
{
$(this).dialog("close");
}
},
//this is important it destroys and remove the dynamically create dialog when you close them so you don't get 20 dialog not displayed in your html markup.
close:
function()
{
$(this).dialog('destroy').remove();
}
}
);
}
);
}
);

I'm using the jQuery UI Dialog function and upon close, I would like to hide one of the elements which was in my dialog.
I'm attempting to do this within the close event of the Dialog function but it's not working. I am guessing because that element no longer exists at the time of close.
Here's the code.
// Dialog settings for our edit dialog's
$("#myDialog").dialog({
autoOpen: false,
close: function(event, ui){
$("#myDiv").hide();
}
});
<div id="myDialog">
<div id="myDiv">This div should hide when the user closes the dialog, but it stays open when I re-open the dialog.</div>
</div>
myDialog and everything inside it, including myDiv, should automatically be hidden when the dialog is closed. You don't need to write any additional code to make that happen. If isn't working, then something else is wrong. My guess based on the code sample in your question:
Hide myDialog by default, e.g., <div id="MyDialog" style="display:none;">...
Explicitly open the dialog when appropriate, e.g., $("#myDialog").dialog("open");
you probably just need to reference those elements relative to the dialog.
$("#myDialog").dialog().find('#myDiv').hide()
-edit-
close: function(event, ui){
$(this).find('#myDiv').hide()
}
I'm working on an application where I'm opening a modal dialog box. The dialog box allows the users to add checkboxes like criteria to the modal dialog div being displayed. They enter the text for the checkbox into a textbox on the page, and click a button to append the checkbox. The checkbox shows up just fine. Next to each checkbox, I'm also adding a jquery ui-icon icon-close image class so that when the X next to the new entry is clicked, the entry is removed from the page.
The problem lies in the fact that simply having the script specified in the page doesn't work. The div doesn't appear to be a part of the page and defining an onclick listener for all images doesn't do what it's supposed. So my question is, how can I define an image onclick listener within the modal dialog. For example, in defining the modal dialog box, I can specify an on open function that does something whenever the dialog box is first opened. I want to, in similar fashion, define a function that is actively listening for whenever an image has been clicked within the modal dialog box.
Example:
$("<div class='rationale' style='position: relative;'><div class='rationaleContainer' style='display:block; height:155px; overflow-y: scroll;'></div><div class='rationaleText' style='position: absolute; bottom: 0; float: right;'><input type='text' placeholder='Add rationale' id='rationaleBox' style='width: 540px;' maxlength='180'></div></div>").dialog({
height: 300,
width: 600,
modal: true,
closeOnEscape: false,
resizable: false,
title: "Comments for " + item,
open: function(event, ui){
$(".ui-dialog-titlebar-close").hide();
$(".ui-dialog-title").after("<i style='font-size: 12px; float: right;'>("+value+")</i>");
$(".ui-dialog .ui-dialog-buttonpane .ui-dialog-buttonset").css("float", "none");
},
Similar to the open function being defined, I want to create a listener for image clicks
To define a global handler which listens when a element is clicked, use the on function on jQuery 1.7 or above. For example:
$(document).ready(function() {
$('.ui-dialog .icon-close').on('click', function() {
// an element of *.icon-close* within *.ui-dialog*
// had been clicked
$('ui-dialog').hide();
});
});
If you are using a version of jQuery prior to 1.7, then use delegate instead of on like this:
$(document).ready(function() {
$('.ui-dialog .icon-close').delegate('', 'click', function() {
// an element of *.icon-close* within *.ui-dialog*
// had been clicked
$('ui-dialog').hide();
});
});
I didn't find this in the documentation.
Should I just make the close button display:none with css, or is there a clean way in the API to make a dialog without the X button (top-right)?
This may solve your Problem:
$("#dialogId").dialog({
closeOnEscape: false,
open: function(event, ui) { $(".ui-dialog-titlebar-close", ui.dialog).hide(); }
});
There is no option to disable the 'X' button. You would need to add css to display none/hide() the element with the class 'ui-icon-closethick' when it is loaded and opened.
For some reason .hide() did not work for me. This did:
$('#divMsg').dialog({ title: 'Please wait...',
modal: true,
closeOnEscape: false,
open: function (event, ui) { $(".ui-dialog-titlebar-close", ui.dialog).css('display', 'none'); } }).text('Text To Display').css('background', 'white');
This code snippet also shows how to set the title and text of the dialog box -- I am using it as a modal notification window and closing it when my AJAX call completes.
I am using JQuery's $.dialog(), where I open a dialog with OK and Cancel buttons.
I would have expected that when the dialog opens, the code stops, and would first continue, when the user had selected OK or Cancel.
Here is my complete source code
http://pastebin.com/uw7bvtn7
The section where I have the problem is at line 127-151.
$("#dialog:ui-dialog").dialog("destroy");
$("#dialog-confirm").dialog({
resizable: false,
height: 600,
modal: true,
open: function() {
$(this).children('div.dialog-text').replaceWith("<h3><b>Users</b></h3>" + makeDialogTable(users) + "<h3><b>Owners</b></h3>" + makeDialogTable(owners));
},
buttons: {
"Okay": function() {
$(this).dialog("close");
},
Cancel: function() {
is_okay = 0;
$(this).dialog("close");
}
} // buttons
}); // dialog
alert(is_okay);
What the code does right now is to first show the dialog and then the alert(is_okay) on top.
What I would like is that the code first continues when the user have pressed OK or Cancel.
How could that be done?
You can put your additional code in the "Okay" and "Cancel" button functions. For example:
"Okay": function() {
$(this).dialog("close");
alert(is_okay);
},
That can't be done in a "good" manner plus I strongly recommend not to go that way.
What you describe is a complete blocking, modal window/dialog which is just aweful for web applications. You're already creating the dialog with the modal flag, so a user can't really do anything on your site while the dialog is open, BUT the UI keeps responsive.
Again, there is actually no way to "hold" code execution. Any approach in that direction would freeze the UI thread since Javascript and UI updates share the same thread.
Since quite a few years, developers pushed Javascript to be more and more non-blocking (Javascript in browsers actually always followed that route, which is very good thing). The idea was reborn with nodeJS on the backend. So, you're swimming upstream here, don't do it.
Whatever the problem is you try to solve there, try to think in different way. Think functional, use callbacks and events, think... ECMAscript! :p
The code does execute sequentially. The job of $("#dialog-confirm").dialog() is to popup a dialog box. alert(is_okay) won't execute until the lines above it have been executed. But Okay and Cancel are event listeners.
"Okay": function() {
$(this).dialog("close");
}
The code above assigns event listeners to events. That's all it does, it does not execute those functions, it just assigns those functions to event calls.
I would recommend doing some reading on events and event listeners. If you plan on using JQuery seriously, it will save you a lot of confusion.
$("#dialog-confirm").dialog({ ...
close :(event, ui) { alert(is_okay);}
})
Or you can bind function later :
$( "#dialog-confirm" ).bind( "dialogclose", function(event, ui) {
alert(is_okay);
});
The code doesn't stop and continue like it does with alert , but it will display message only when dialog is closed.
Simply put all code that follows after opening the dialog in a function and call that function from the dialogs callback function for okay / cancel.
function doTheRest(args) {
alert(args);
}
// snippet from dialog options
"Okay": function() {
$(this).dialog("close");
doTheRest(1);
},
"Cancel": function() {
$(this).dialog("close");
doTheRest(0);
}
Browsers use an event-based, asynchronous programming model where many things can (and do) occur at the same time. This is how style-transitions (animations like rolldown or fade) work.
Your example displays a dialog and then throws an alert. It cannot "wait" for the user to click on a button because doing so would stop the browser from doing anything else.
So you'll need to refactor your code to do whatever you require to happen when either the OK or Cancel buttons are clicked within the callback associated with the action.
In other words, you need to:
buttons: {
"Okay": function() { // this function is called when a user clicks the Okay button
// do whatever work is required here
}
}
There is no direct way to "wait" for something in JavaScript -- asynchronous events are generally handled through callbacks. This means you need to think of your program in terms of events and not as sequential code. Instead of your current code:
$("#dialog-confirm").dialog({
...
});
alert(is_okay);
// rest of code
you need to wrap the "rest of code" section into its own function, then call that from the OK/Cancel callbacks of your dialog:
$("#dialog-confirm").dialog({
...
buttons: {
"Okay": function() {
$(this).dialog("close");
what_happens_if_okay();
},
Cancel: function() {
$(this).dialog("close");
what_happens_if_not_okay();
}
} // buttons
}); // dialog
So if I understand correctly you want an alert to show up with the options OK and Cancel and the Dialog would not come up unless OK was hit.
Instead of using another alert why not try using another dialog with Ok and Cancel in it?
In your html do this:
<div id = "hiddenDialogElements">
<button id = "Ok" onclick = "confirm(true)">OK</button>
<button id = "Cancel" onclick = "confirm(false)">Cancel</button>
</div>
With this css:
#hiddenDialogElements
{
display: none;
}
Then you can do this on the event that will create the dialog (Where you want a wait):
$('#hiddenDialogElements').dialog({
//Code
});
And this:
function confirm(ifOk)
{
if(ifOk)
{
//Create Dialog
}else {
//Do nothing
}
}
Do Something Like this ...
function MyAlert(Message, Title,FuncExecAfterOkPressed) {
$("<div>" + Message + "</div>").dialog({
title: Title,
dialogClass: "alert",
width: "auto",
modal:true,
open: function (event, ui) { $(".ui-dialog-titlebar-close").hide(); },
buttons: [
{
text: "Ok", click: function () {
$(this).dialog("close");
if (FuncExecAfterOkPressed != null) {
$.Callbacks().add(FuncExecAfterOkPressed).fire(null);
}
}
}]
});
}
Now Call it like this
MyAlert(data, "Duplicate", function () {
alert("I m moumit");
$("#Name").val("");
});
One thing u need is JQueryUI plugin... Enjoy.
Here is the code I'm using
http://jsbin.com/evike5/edit
When the jQuery UI dialog is fired second time. The updated title is not shown.
Am I doing something wrong?
This is because you're opening the same dialog, for it to take effect you either need to destroy the old dialog, like this:
$("#hello").dialog('destroy').attr("title", "Helloooooooo!")
Try it here.
Or just set the title and button behavior without re-creating the dialog, like this for your OK button:
OK: function () {
$(this).dialog("close")
.dialog("option", {
buttons: {
OK: function () {
$(this).dialog("close");
}
},
title: "Helloooooooo!"
}).dialog("open");
}
You can give that a try here.
