I have got a jqgrid, and i would like to put a link in it to open up more details on the row in a modal window.
Everything i have read about modal windows uses a div that gets shown when you click the link, but i want to pass an id so i can just get the info i need. I know i could do it with a new window quite easly but i would like to use a modal window if poss.
Any ideas how i could do this. I'm using asp.net if thats going to be relevent.
Cheers

I'd suggest using the jQuery UI Dialog plugin for custom modal windows. You can find demonstration and documentation here:
http://jqueryui.com/demos/dialog/
In theory, to do what you're asking for, you could follow these steps:
Add a “dialog” div tag to your page.
Build the link into your data feed. If you’re using a XML data type make sure you use a CDATA flag to encapsulate your link so that they XML may be parsed correctly.
< cell>< ![CDATA[< a href=”javascript:showDialog(‘551’)”>text]]>< /cell>
In this instance, since we know the actual id at the time the link is create, I pre-populated the id (e.g. 551) in the function. This could also be retrieved from jqGrid API with the selrow property. It’s your call. If you use a JSON data type, the idea would similar. You wouldn’t have to worry about the CDATA qualifier.
Create a local function (e.g. showDialog (id)) to correspond to your link.
Add code in the showDialog function to populate and open the modal dialog. Using an AJAX call to gather specific data for this record, create the dialog content and populate the dialog using the jQuery .html method.
function showDialog (id) {
$.ajax({
url: "feed.aspx?id=" + id,
success: function(data) {
var content = // TODO: create dialog layout here
$("#dialog").html(content);
$("#dialog").dialog({
title: 'Record Details',
modal: true,
closeOnEscape: true,
width: 300,
height: 200,
buttons: false,
position: "center",
});
$("#dialog").dialog("open");
}
});
}
This is just one way to skin the cat. You should be able to use more of a jQuery approach with the link creation. If desired, rather than building the specific link the data feed, you could add jQuery click event bindings to handle the request. It’s your call. You could also add the dialog div dynamically to your page using jQuery rather than just placing it manually like I described above. It might be a little more elegant looking but would achieve the same goal.
I am attempting this late. May be you have an answer. Thought this will help others.
The #dialog code can be done as suggested by gurun8. This needs to be wired to the jqgrid. There is a onSelectRow event which triggers whenever a row is selected in jqgrid. Refer documentation. I usually add autoOpen: false, to the dialog constructor.
You need to add the onselectrow event to the grid (jqgrid function as shown below) and you can pass the id to the function. This id is the unique identifier in the jqgrid. Make sure there are no syntax errors, add comma wherever appropriate.
$s("#list").jqGrid({
...
onSelectRow: function(id){
console.log("row is selected"+id);
$url = "your_url/";
$s('#dialog').load($url);
$s('#dialog').dialog('open');
}
...
});

I have an FileUpload control on a page. I need to change some values based on the filename once a user selects a file. I'm trying to find out the best way to do this. The only option I can see is listening in JavaScript for a change event and then either..
a) forcing a post back and updating the form
b) updating things on the client side using JavaScript and some back end async calls.
Is there any other options and if not which of this is preferable?
Thanks
If you are using jquery, you can attach a function to the change of the file upload.
Consider the following example html:
<input id="myFile" type="file">
<p><label id="myLabel">No File</label></p>
And let's say we wanted to update the label with the name of the selected file. To do that, we'd use the following javascript:
$(document).ready(function () {
$("#myFile").change(function () {
$("#myLabel").html($(this).val());
});
});
Here's a fiddle in action: http://jsfiddle.net/ffkuL/1/
If you aren't using jquery, you can do something like this:
var upload = document.getElementById("myFile");
upload.onchange = function (e) {
var label = document.getElementById("myLabel");
label.innerHTML = this.value;
};
And here's a fiddle for that one: http://jsfiddle.net/8PYwK/
(Honestly, though, I find that it's far simpler in the long run to use jquery in the long run when dealing with ASP.NET controls.)
Obviously, the label changing in my samples are just examples. Following that pattern, though, you can make whatever changes you need to on the client side (rather than needing to post back).
The jQuery UI dialog drives me up the walls. To the best of my understanding, here's how it works:
When you do $('#myDialog').dialog({...}), it copies the #myDialog element and moves it inside this bizarre widget thing at the bottom of your body tag. This is crazy! It will duplicate possibly unique DOM elements (with ids) when it does this.
So what I'm trying to do is make it behave in a predictable way when I refresh the HTML of the original element (#myDialog). If I do this dynamically, sometimes the dialog doesn't open any more:
http://jsfiddle.net/t67y7/3/
Or sometimes the dialog opens with the old HTML (because it's cached at the bottom of the page that way). What is up with this?
Since nobody seems to have any idea how to tame this beastly dialog, here's the best thing I've come up with to date. I'll accept any superior alternatives.
var original = $('#dialogId')[0];
var clone = $(original).clone().attr('id', 'dialogIdClone');
var saveHtml = $(original).html();
$(original).html('');
$(clone).dialog({
... // other options
open: function (){
// add any dynamic behavior you need to the dialog here
},
close: function(){
$(clone).remove();
$(original).html(saveHtml);
}
});
The purpose of this whole craziness is to keep the HTML of the original dialog unique on the page. I'm not really sure why this can't be the built-in behavior of the dialog... Actually, I don't understand why jQuery UI needs to clone the HTML to begin with.
I know this has been posted for a while, but a less extensive way to handle this issue would be:
$('#your-dialog').dialog({
... // other options
open: function (){
// add any dynamic behavior you need to the dialog here
},
close: function(){
}
});
$('#your-dialog').remove();
This is due to dialog widget wants to be able to control the display and will wrap the inner content of the original dialog then create a brand new one at the bottom of the body.
The draw back of this solution is that the dialogs have to be the first to be initialized to ensure all your 3rd party library widget will operate properly.
Why don't you just call $("#dialogId").dialog("destroy") on close function, like this:
$("#dialogId").dialog({
close: function() {
$(this).dialog("destroy");
// you may want empty content after close if you use AJAX request to get content for dialog
$(this).html('');
}
}
The destroy function will remove the decorated code, and your dialog element will not be duplicate next time you show the dialog.
I added a sample code to jsfiddle.net example.
You need to empty the dialog before opening it.
$("#dialogId").html('');
$("#dialogId").dialog({
close: function() {
$(this).dialog("destroy");
}
}
hi i have installed scheduler module from drupal.org. and i have set all the settings regarding this. now i can set publish and unpublished date in text box(there is format of date below text box).
i want to use java script calendar so when user click on the text box ,the calendar should open.
how can i do this
Since you're using Drupal you should have JQuery preloaded. You don't necessarily need JQuery to do this but it makes it easier, you'll use JavaScript either way.
With JQuery, simply setup a click listener on the textbox and have it call the whatever function triggers the calendar display like so...
Note: I used a simple ID selector below "#textbox" replace it with whatever way you want to select your textbox input. (eg. if you've given the HTML textbox input element an ID of "textbox" you can use my example)
$(document).ready(function(event) {
$('#textbox').live('click', function() {
//call your function here
});
});
just need tips on how to make forms where request are submitted via AJAX with a loading progress image. I am using update panels with AJAX framework. I would like to know about the recommended approach. Through JQuery or AJAX toolkit ?
Please advice, examples would be an added bonus for me.
1- Prepare a client side div with "display:none" style property. put your loading image inside.
2 - when the user or page submits a request, change that divs display property to "block".
3- Add some kind of "information received" sign to the response and check this response from the client side and then change that divs display property back to "none"
I would like to know about the
recommended approach
Well, that depends on what you are doing, what parts of the form are you updating, how big is the form, what values are you sending to the server.
Generally speaking, if you want to update something simple (dropdownlist, listbox, etc), youd generally use JavaScript (or jQuery) to call an AJAX-enabled web service. This way, you're only sending to the server the data it needs, things like ViewState/cookies are not sent over the wire. You also have full control over the pre/post execution events (so you can add your loading images, call the WS, then clear them).
However, if you want to asynchronously update an entire form (which has a lot of controls), you're probably right in using an UpdatePanel. Things like a GridView are a good case for an UpdatePanel (as you usually need to handle editing, binding and paging all asynchronously).
The progress image is made easy with the following code:
<ProgressTemplate>
<img src="someloadingimage.gif" alt="Loading" />
</ProgressTemplate>
Stick that inside your UpdatePanel, and whenever an AJAX call is made, the loading image will be shown.

If you use JQuery for AJAX request then you can use the following events -
$.ajax({ url: "test.html",
type: "GET",
beforeSend: function(){
-----load your loader here-----
});,
success: function(){
------remove your loader here -----------
Remaining code
}});
You can also use POST. in above example i have used GET.
For detailed documentation you can refer - http://api.jquery.com/jQuery.ajax/
Create a small plug-in for your loader like so.
$.fn.ShowLoader = function(on){
switch(on)
{
case true:
$(this).show();
break;
default:
$(this).hide();
break;
}
}
then use the following:
$('form').submit(function(){
var Form = $(this);
$('.loader',Form).ShowLoader(true);
//Gather some params
Location = Form.attr('src');
Data = Form.Serialize();
$.post(Location,Data,function(result){
result = result || false;
if(result)
{
$('.loader',Form).ShowLoader(false); //Disable the loader
//Process result
}
});
})
html would just be a regular form, with an image / div inside with the class of loader
I've got an asp.net page containing a Textbox with an Autocomplete extender on it.
It's setup so the user can type a short reference code into the textbox and then choose from the list of matching codes returned by the autocomplete.
On the "select", I then call the server using JQuery. I'm currently using $.get here....
The callback function from $.get checks for "success" and then displays a simple-modal dialog containing info about the item they've just selected.
if (sStatus == "success") {
$.modal(sText, {
overlayClose: true,
appendTo:'form',
onShow: function(dialog) {
$("#ccTargets_tabContainer").tabs();
},
onClose: function(dialog) {
$("#<%=TextBox1.ClientID%>").val("");
$.modal.close();
}
});
$.ready();
}
One of the bits of info being loaded here is a JQuery TABS setup, so the onShow function of the simplemodal is used to initiate the tabs which are within the simplemodal.
Now to the crux of my problem.
If I do multiple consecutive "autocompletes" on the same page it all works fine Unless I have selected a different tab on the tabs in the simplemodal ....If I select a different tab, close the simplemodal and then do another autocomplete I get a JQuery error which seems to relate to a selector doing something with the "old" selected tab that was on the "closed" modal.
I'm clearly missing some sort of cleardown / initialisation somewhere, but can't find what it is. Help?
I've tried "tabs.destroy" before the modal call in the code above and I've tried a $.ready() call as indicated too....
UPDATE: Is it something to do with JQuery Tabs appending my addressbar URL with the selected tab's ID?
I've found the problem.
It's with the "history" script that the tabs plugin normally uses. Obviously as I am continually creating and destroying popups there is no history to speak of - it's all done outside of the normal app navigation.
I've removed the jquery.history_remote script and now it works just great!
