I am using ion.RangeSliders and I need to initialize about 10 sliders. So I decided to use JavaScript Class constructor method.
This is what I've done:
...ANSWER
Answered 2021-Apr-06 at 14:25var table = $("#example").DataTable();
class IonRangeWrapper {
inputFrom = null;
inputTo = null;
table = null;
slider_range = { from: 0, to: 0 };
constructor(range, min, max, inputFrom, inputTo, table) {
var _this = this;
this.inputFrom = inputFrom;
this.inputTo = inputTo;
this.table = table;
range.ionRangeSlider({
type: "double",
min: min,
max: max,
from: min,
to: max,
onStart: (data) => _this.update(data),
onFinish: (data) => _this.update(data)
});
var instance = range.data("ionRangeSlider");
inputFrom.on("input", function () {
var { to } = _this.slider_range;
var val = $(this).prop("value");
if (val < min) { val = min; }
else if (val > to) { val = to; }
instance.update({ from: val });
});
inputTo.on("input", function () {
var { from } = _this.slider_range;
var val = $(this).prop("value");
if (val < from) { val = from; }
else if (val > max) { val = max; }
instance.update({ to: val });
});
}
update(data) {
var from = data.from;
var to = data.to;
this.slider_range = { from, to };
this.inputFrom.prop("value", from);
this.inputTo.prop("value", to);
this.table.draw();
}
}
// Age Slider
var rangeAge = $(".rangeAge");
var inputFromAge = $(".inputFromAge");
var inputToAge = $(".inputToAge");
var minAge = 10;
var maxAge = 70;
new IonRangeWrapper(rangeAge, minAge, maxAge, inputFromAge, inputToAge, table);
QUESTION
I tried to get the value of the check box for each row I have two textbox to store it and separate each value by comma. The problem is when I paginate or use search in datatable the value of two textbox is resetting with the value that I checked in another page or search. It should be continuously storing the value.

QUESTION
I have a table which loads the data by crating all the elements inside the table dynamically. Something similar to datatable. Now, every time I regenerate the tbody for the next page, the column width changes based on text length and it changes the table width. I tried table-layout: fixed and td {width: 1%} but they don't work. I want to keep the table column width same as the header text width. How can I achieve that?

QUESTION
In a nutshell: I need to calculate the Hurst Exponent (HE) across a rolling window inside a pandas dataframe and assign the values to its own column.
The HE function I use was lifted from here as it seemed more robust. For convenience it's posted below:
...ANSWER
Answered 2021-Feb-15 at 21:21I think your problem is that your window is too short. It says in the docstring that the window length has to be 100+ elements, and the Hurst code isn't handling it properly, resulting in a failure of the SVD.
Separately, your test is actually slicing everything but the last 20 elements, so is actually a long array, which is why it didn't fail:

QUESTION
What I'm trying to do is set up a table just like this: https://datatables.net/examples/basic_init/alt_pagination.html
Copied the code but then no success. I've tried so many different variables and removing all but the necessary code and I'm at a loss for what the issue may be.
I've gone through several other similar SOF questions and some mentioned "sDom" could be the case so I tried a few variations I've found online but no luck yet.

...ANSWER
Answered 2020-Nov-06 at 10:26You may well have tried some or all of these, but here are some thoughts which may help:
Make sure you're not using any configuration from the legacy version of datatables. You are using 1.10+ - so make sure that you use the correct v1.10 config.
Get it working without any Django tags first - just a standalone page. Then integrate the tags in stages so that you check it still works.
You can start with this example - get this working first and then add in the correct options as you need them.
Make sure you take some time to read the documentation - the datatables documentation is really good, and spending a bit of time on reading and understanding it will save a lot of time in the long run.
Also, try declaring your css / js imports in the HTML .
To start - just remove all the options and use the defaults:
QUESTION
I am having issues with changing the color of the buttons "Print","Excel",&"PDF". I have checked out this reference, but when I followed it, I was still unsuccessful. The test case I have included below is different from my code, but the CSS and button initialization should be the exact same. I chose to use it just because it is static data, and my AJAX call that pulls from SharePoint doesn't work on external sites.
The button by default is white, but I want it to be dark grey to match my table's header row.
Here is a test case snippet of the code.
...ANSWER
Answered 2020-Sep-09 at 17:58The problem was your css in stackoverflow was implemented before the datatables.min.css.
So you need to make sure that in your application it should be after.
If that cant be done you can use !important but its not preferrable
or you can use the below code
QUESTION
I am using jQuery DataTables and applying Individual column searching (select inputs). So on table footer, there is a select on each column to filter data.
I implemented ColReorder extension which gives you the ability to reorder columns in a DataTable through a click and drag operation.
It works fine but when I drag a column let's say 'Office' in my example and drop it as the first column then I select an option for example 'London' I get 'no matching result'.
The reason is: the search is still using the initial column index before reordering. So it's basically searching 'London' in column 'Name' as it was the first column before reordering.
I found some threads on how to apply column filtering with column reordering as here but couldn't make it work.
I used column.index( 'visible' ).search( val ? val : '', true, false ).draw();
Also
...ANSWER
Answered 2020-Jul-27 at 22:46You can use the column-reorder event to track changes to column ordering.
This requires a bit of logic, because each column re-order is only tracked in terns of how it differs from the previous order - and here we need to track how it changes in comparison to the original column order.
Here is an event function to handle that:
