I'm working on an app that handles some kind of reservations by time and by court (Tennis court). I don't use tables, instead I use divs to draw a table. Horizontally I have 'courts' while vertically I have 'hours'. If user clicks on one div, let's say 'court 1, 10:00h' I store that as one event. The point is, some of reservations should be for 2h and more. So I would love to create some kind of 'drag-select' which will highlight few divs, i.e. 'court 1, from 10:00 - 12:00'. After that I would store start and end to the db.
How would you approach this problem? I didn't find any similar package that I can use.

Situation:
I have a pandas dataframe which I convert into an html table via df.to_html(). I then add the DataTables class to the table. This DataTables-table has the following columns:
ID | X | Y | Val |...More columns...| Selection_Criteria |...More columns...
The values in Selection_Criteria can be either 1 or 0. I know that with:
$('#ProductList').DataTable( {
...
"fnInitComplete": function(oSettings, json) { $('#ProductList tbody tr:eq(0)').click(); }
});
(Source: http://code.datatables.net/forums/discussion/38171/automatic-select-of-the-first-row-on-reload)
..it is theoretically possible to select the first row. (In reality, I have not been able to simulate a click for the first row.)
But my question goes more towards: How do I automatically pre-select ALL rows where the value is 1 in Selection_Criteria? What is the best approach? Should this be done client/server side?
In pandas the term "select"(ing) means to screen out that which was not selected for. I know that in a table on a web page, selected can mean being highlighted to stand out from the others. There are a couple of ways you can do this on the server side. You could display two tables, one for each state of Selection_Criteria. This would save you the hassle of trying to select individual rows out of a table in the first place (which would be done with Javascript, not Pandas). While pandas has the ability to add a class to the resulting html, the class is applied to the element.
If you are using jquery you are going to use these pieces. as you haven't put example data I can't be exact.
replace x in the next line with the number of columns the Selection_Criteria=1 is across the table
$( "tr td:nth-child(x):contains('1')" ).addClass('selected');
There are solutions on the backend using beautifulsoup and css selectors, or lxml.etree with xpath selectors. But jquery is going to be the most concise with this problem.
#Aliester. Thank you for the pointer!
This helped me find the solution to my own question. What I did:
1.) Identify row index that I want to select when the table loads.
2.) Pass the index to js.
3.) Loop over the indices and apply the following command to each index entry:
table.row(':eq('+hit_index_row+')').select();
So I am using the API to select each individual row. This works for me and hopefully could be helpful to others as well. It may be a bit hacky, so more elegant suggestions are welcome!
You can do this by providing a function for the "rowCallback" option when initializing the DataTable. https://datatables.net/reference/option/rowCallback
Also it is generally better to use the API methods to select rows instead of just changing the class. I found that the DataTable + Select libraries keep an internal collection of selected row indexes (just current page if serverside processing is on) instead of using the class to resolve selected items.
So while the display will look right, if you just change the class, if you rely on any of the API methods to get selected items later on there will be issues. Additionally just changing the class on the row will not fire any of the "select" events on the table so you can't rely on those either.
I was wondering how feasible is to add some compound elements (nodes) "on the go".
Scenario:
I have a network with nodes from n1...n10 and edges. Depending on the button the user clicks, it redraws my network including nodes inside a compound node.
Example:
When you open the graph, you have n1..n10, without compounds, but when you click on a pre-defined button, my new graph now would be:
A new compound node with n1:n5 inside (parent), and the rest n6:n10 would stay the same (outside compound).
How feasible is it ?
I've tried :
cy.batchData({
"5": {
parent: "n0" // new element I added earlier
}});
to update my element id=5 to have n0 as parent, but it haven't worked.
The main idea is to represent data (graph) with biological insight, where the "new compound area" would be a pathway or a metabolic path (or whatever I want to represent there), one by one, so the visualization won't be a mess.
Thank you.
You can't change the parent field; it's immutable. You may have to remove the elements and add the second (resultant) graph via eles.remove() and cy.add() respectively.
I have a requirement to create a xaml page with Semantic Zoom where the zoomed in view contains both GridViews and ListViews. I have started out with the basic Grid Application template.
In order to try to achieve this, I have made the Semantic Zoom control's zoomed in view show a list view, and the list view contains the ListView and GridView controls I need to actually show the data as ListViewItems. This works, up to a point - the issue is that the mouse-down or tap animations happen on the whole child control of the parent ListView instead of the child's elements. This sort of layout would be simple if I didn't need to support semantic zoom.
So, my question is is this the best way to achieve this sort of layout, or am I missing something. If this is the best way, is it possible to control the behaviour so that the child item elements have the correct animation effect on selection?
Additional Info
The choice of GridView or ListView is based on the type of the items in the collections. In this example, grp 1, 3 and 4 (to be shown in grids) are all collections of type NewsFull and the remainder (to show in Lists) are of type HeadlineOnly, both types inherit from NewsBase.
The page layout (zoomed in) should be something like this...
Title
grp 1 grp 2 grp 3 grp 4 grp 5
[g][g][g][g] [_list item_] [g][g][g][g][g] [g][g][g] [_list_item_]
[g][g][g][g] [_list item_] [g][g][g][g][g] [g][g][g] [_list_item_]
[g][g][g][g] [_list item_] [g][g][g][g] [g][g] [_list_item_]
[g][g][g] [_list item_] [g][g][g][g] [g][g]
where [g] is a grid view item, and [_list_item_] is a list view item.
Zoomd out view is like this...
Title
grp 1 grp 2 grp 3 grp 4 grp 5
[summary] [summary] [summary] [summary] [summary]
Perhaps you can try using the ItemContainerStyleSelector to swap out the container of the items based on the item type or similar? This way, may be you can set one group to have a wrapping layout container and another can just be a stackpanel?
the design looks reasonable to me. the issue you have is merely " is it possible to control the behaviour so that the child item elements have the correct animation effect on selection?"
the problem here is that you probably lack abstraction here regarding different levels of UI object. I would assume you wrote this big control simply using one xaml object and then messed up with the style setup. In my opinion, you will need to break your UI to these levels of components:
ZoomPage // which is essentially a list
GroupElement // which could be GRID object or list object depending on the DATACONTEXT
GroupElement // which also has a summary state.
what you specified definitely can be achieved, looks to me just the styles are not deployed properly, if indeed your control is too complex, break it down, and test them separately.
hope this helps
I have a zend form which is using a view script. I want to get access to the individual radio button items but I'm not sure how to do so. Right now, I just print them all out using:
echo $this->element->getElement('myRadio');
That prints them all out vertically. I need a little more control. I need to be able to print the first 5 options in one column then the next 5 in a second column.
I have the same issue. There is no nice way to do this that I have found (circa ZF 1.10.8)
Matthew Weier O'Phinney had some advice on this page:
http://framework.zend.com/issues/browse/ZF-2977
But I find that approach cumbersome in practice. The original poster on that ticket had a good idea, and I think they should ultimately incorporate some nice way to do this along those lines.
But since there is no better way at the moment, I just follow Matthew's suggestion for now.
For my form I was working on, to render just one single radio button out of the group, I had to do this:
In my form class:
$radio = new Zend_Form_Element_Radio('MYRADIO');
$radio->addMultiOption('OPTION1', 'Option One')
->addMultiOption('OPTION2', 'Option Two');
$this->addElement($radio);
In my view script, just rendering OPTION1:
echo $this->formRadio(
$this->form->MYRADIO->getFullyQualifiedName(),
$this->form->MYRADIO->getValue(),
null,
array('OPTION1' => $this->form->MYRADIO->getMultiOption('OPTION1'))
);
That will render a <input type="radio" /> element, and an associated <label>. No other decorators will be rendered, which is a pain.
For your case, you will probably want to render your radio elements and other elements using the ViewScript view helper - so you can line all of the elements up amongst your own custom table markup as you described.
Figured this one out too. Just use
$this->element->getElment('myRadio')->getMultiOptions();
and it will return an array of the key/value options.
I'm using Dojo.dnd to transfer items between to areas. The problem is: the items will snap into place once I drop them, but I'd like to have them stay where I drop them, but only for one area.
Here's a little code to explain this better:
<div id="dropZone" class="dropZone">
<div id="itemNodes"></div>
<div id="targetZone" dojoType="dojo.dnd.Source"></div>
</div>
"dropZone" is a DIV that contains two dojo.dnd.Source-areas, "itemNodes" (created programmatically) and "targetZone". Items (DIVs with images) should be dragged from a simple list out of "itemNodes" into "targetZone" and stay where they are dropped. As soon as they are dragged out of "targetZone" they should snap back to the list inside "itemNodes".
Here's the code I use to create the items:
var nodelist = new dojo.dnd.Source("itemNodes");
{Smarty-Loop}
nodelist.insertNodes(false, ['<img class="dragItem" src="{$items->info.itemtext}" alt="{$items->info.itemtext}" border="0" />']);
{/Smarty-Loop}
But this way I just have two lists of items, the items dropped into "targetZone" won't stay where I dropped them. I've tried a loop dojo.query(".dojoDndItem").forEach(function(node) to grab all items and change them to a "moveable"-type:
using dojo.dnd.move.constrainedMoveable will change the items so they can always be moved around (even in "itemNodes")
using dojo.dnd.move.boxConstrainedMoveable and defining the "box" to the borders of "targetZone" makes it possible to just move the items around inside "targetZone", but as soon as I drop them, I can't grab and move them back out. (Strange: dojo.connect(node, "onMoved" doesn't work here, the even won't fire, no matter what.)
So here's the question: is it possible to create two dnd.Sources where I can move items back and forth and let the items be "moveable" only in one of the sources?Or is there a workaround like making the items moveable and if they're not dropped into "targetZone" they'll be moved back to the list in "itemNodes" automatically?
Once the page is submitted, I have to save the position of every item that has been placed into "targetZone". (The next step will be positioning the items inside "targetZone" on page load if the grid has already been filled before, but I'd be happy to just get the thing working in the first place.)
Any hint is appreciated.
Greetings, Select0r
There is no direct support for such features. It can be done with a custom code, e.g., by subclassing a Source and overriding its insertNodes().
Here's a quick workaround to get this working:
I ended up using only one DIV which is a dojo.dnd.Source and contains the items that should be dropped into a "dropZone" and moved around in it while snapping back to the item-list when placed outside the dropZone.
All items are a dojo.dnd.move.parentConstrainedMoveable to make them movable in the originating DIV. Connecting to onMoveStop will give me the opportunity to decide whether the "drop" has occured in the dropZone or somewhere else.
if (coordX >= (dropCoords.l + dropAreaX) &&
coordX <= (dropCoords.l + dropAreaX + dropAreaW) &&
coordY >= (dropCoords.t + dropAreaY) &&
coordY <= (dropCoords.t + dropAreaY + dropAreaH))
{
// OK!
}
else
{
// outside, snap back to list
}
dropAreaX and dropAreaY contain the coordinates where the dropZone starts, dropAreaW and dropAreaH contain its width and height.
If "OK!", the items will be saved into an array, so I know which items have been dropped. Otherwise the item will be removed from that array (if it's in there) and the item will be placed back into the list (via CSS "left: 0"). The number of elements in the array will tell me how many elements are left in the list, so I can "stack" them in a loop using "top: numberOfElement * heightOfElement px").
There's more to it as I need the items coordinates written to hidden fields, but I guess this should get anybody who's working on a similar problem on the right track.
