i need to display tooltips for my table cells. Are there any plugins for that purposes?
Thanks in advance!
You should be able to use any table and tooltip plugins you want - you just need to trigger the tooltips correctly depending on how you are initializing and updating the table.
For example, if you use jQuery DataTables (which I assume you are looking at given the tag you gave your question) with the jQuery UI tooltip widget you could simply initialize the tooltips once you've initialized the table. If you have the tooltip data already in the table, it could be as simple as:
$('#mytable').dataTable().tooltip();
If you have a more complex table that gets updated (such as using deferred rendering for a giant dataset), then you'd probably need to tie into the row creation callback to get the tooltips on any new rows by doing something like this in the init options:
"fnCreatedRow": function (nRow, aData, iDataIndex) {
$('.tooltip', nRow).tooltip()
}

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'm on ExtJS 4 and using an MVC approach. I've created a simple grid view class, and have added a componentquery type 'ref' to that view in my controller. Within the initial grid view itself I set several columns to be hidden and some to be visible by default. The rendering of the grid with those settings is all working fine.
Then I have a button that, when clicked and based on some other conditions, will make some of the initially hidden grid columns visible. This works as well.
But what I need is a way to later 'reset' the grid to its initial view (with the correct columns hidden/visible, as they were initially).
I've tried various permutations of the following with no effect:
var theGrid = this.getTheGrid();
theGrid.reconfigure(store, theGrid.initialConfig.columns);
theGrid.getView().refresh();
I suppose I could loop through every column and reset its 'hidden' state, but would think there's a way to just 'reset' back to what's set in the class? Advice?
SOLUTION UPDATE
Appreciate the pointer from tuespetre. For anyone coming along in the future looking for specifics, here is what was needed (at least for my implementation):
Within the view, moved the column defs into a variable
Within the view, columns ref within the class becomes:
columns: myColumns,
Within the view, the following function created within the class:
resetGrid: function(){
this.reconfigure(null, myColumns);
},
Within the controller:
var theGrid = this.getTheGrid();
theGrid.resetGrid();
You will just need to create a function on your view class to encapsulate that functionality.
I've scoured the dojo documentation, stack overflow, as well as thoroughly explored the EnhancedGrid object itself with firebug, and I'm not finding answers.
I have an enhanced grid that I populate with values for the user to sort on and basically create a selection set (using indirectSelection plugin). They then have a button to zoom to the selected items on a map.
The problem is, when sorting columns, it doesn't change the order of the items in the store itself, where I'm keeping an object inside each item that tells me how to zoom on the map, so I have no way to reconcile the grid.selection.selected array indices with the store._arrayOfAllItems indices.
edit: Note that I'm stuck using Dojo 1.6 as it's baked into the API I'm using.
Have a look at Dojo Object Store Tutorial.
You can set an idProperty to a Store, e.g.:
var employeeStore = new dojo.store.Memory({data:employees, idProperty: "name"});
Then you can operate the store with that id property using the get method like this:
// add a new employee
employeeStore.add({name:"George", department:"accounting"});
// remove Bill
employeeStore.remove("Bill");
// retrieve object with the name "Jim"
var jim = employeeStore.get("Jim");
Instead of using store._arrayOfAllItems. That way your grid.selection object will contain your id's values instead of array indexes (provided that your grid's store property is your store). This is the part that I'm guessing will work because I know for sure that the new dojo's dgrid does it that way, which I encourage you to use it BTW.
Hope it helps,
I'm using Dojo 1.5 (including dojox). I have a dojox.grid.DataGrid where each row represents a user. When I click a row, I want to redirect to a URL like /users/USER_ID. The user ID is one of the fields in the grid, so all I need to do in my onRowClick callback is to grab the user ID for the row that was clicked.
The click event contains a rowIndex property, and, indeed, I found a (rather old) post elsewhere that suggested I should be able to do:
var row = dijit.byId('grid').model.getRow(e.rowIndex);
/* (Then grab the 0th field of the row, which is the user ID.) */
(Sorry, I've since lost the URL.)
But my grid object has no model attribute. What's up with that? Has the API changed? (My grid certainly is populated with data, which I can see, click, sort by column, et cetera).
So I'm stuck for now. Note, BTW, that it won't work to use rowIndex to directly access the grid's underlying dojo.data.ItemFileReadStore. That's because the grid is sortable, so there's no guarantee that the grid's rows will be in the same order as the store's.
Any hints would be deeply appreciated. I hope that the question is clear, and sufficiently general that any answers can help others in my predicament. Many thanks.
I have a similar scenario and I grab the value like this:
onRowClick: function(e) {
open_link(my_grid._getItemAttr(e.rowIndex, 'object_path'));
}
In this case my_grid is a reference to the datagrid and object_path is the column where I store the path to the object. open_link is of course a custom function of mine that as it implies, requests a server path.
So just change the specifics to suite your case and you should be fine.
I am trying to add a row to a slick grid on my page using javascript. The way I am able to do it now is by using the following code. I was just wondering if there was a better way to do the same.
....
//data is the array which was used to populate the SlickGrid
data.push({name:'Finish scanning the slickgrid js', complete:false});
grid.setData(data);
grid.render();
....
This is the preferred way.
data.push({...});
grid.updateRowCount();
grid.render();
Calling .setData() forced the grid to re-render everything. By calling updateRowCount() you are notifying the grid the number of the rows have changed and that it needs to render what has been added or removed only.
Here is what I've been used for adding new row with Button
function add_new_row(){
item = {"id": (Math.round(Math.random()*-10000))
//you can add another fields to fill default data on Adding new row
};
data_view.insertItem(0, item);
}
