gnomx

Hi there. I'd like to know how can I get a text fro a TD by using datatable.
I have a datatable called #myTable. On last TD there's a button that call a modal. I need to know how can I get a text on TD that belong that row.
I've tried a lot of code but every time i got undefined! I'm gonna crazy!

$('#myTable').on('click','#compile',function(){ debugger })

compile is id of my btn that call modal

each row ha its button

Start with this delegated events example. Here is an example with buttons:

You have #compile which doesn't seem right as the IDs need to be unique on the page. If you still need help please build a simple test case showing what you are trying to do so we can offer specific suggestions.

#compile - do you have an element with id="compile" in every row? That isn't valid HTML, each id must be unique.

I would suggest you use a class name rather than an id.

To get the data of a cell you can use cell().data() or for the whole row row().data().

If you link to a test case showing the issue, I'll be able to help further.

but if I use clause $(this) it doesn't referred at that specific row?
Yes I've id inside each TR

kthorngren

Maybe use jQuery closest(), like this $(this).closest('tr).

I've already tried and didn't work. I don't what call server to retrieve information. I want get it from table.

The best next step is for you to build a simple example showing what you have or provide a link to your page. This way we can have an understanding of your solution to provide specific suggestions.

How can I do it?

kthorngren

Are you asking how to create a test case?

I updated my above example so that each row has an id. When clicking the button it will output the row id to the console:

I got it.
Here the working code , I need to test into my modal , but when I click I get TD desired.
<script type="text/javascript"> $(document).ready(function(){ $('#elenco_bonifici_fase2 tbody').on( 'click', 'a', function () { var id = $(this).closest('tr').find('td.ufficio').text(); console.log(id); }); }) </script>

Thanks a lot kevin. I'll try it tomo.

gnomx

ok it works! Now i need to know if I hide an cell from Datatable by using
"targets": [ 6 ],
"visible": false
Is it possible get that information inside it?

kthorngren

Use cell().node().

Kevin

gnomx

No works...td isn't in the DOM but is in the cache.

kthorngren

That is why you use cell().node(), like this:

No works... I'm sorry

gnomx

I leave it not hidden

kthorngren

My example works. If you are having difficulties using cell().node() then provide an example of what you are trying to use so we can help. Or if my test case is not doing what you want then let us know what you are expecting.

I'm so sorry about it. I've moved all code together in js file. So before code was split in two parts.Now works , i got .data() instead .node()
