Get specific row data information on click

[geral]

Hello, is it possible to get the data information from a row where a user clicked on or trying to change? Get only the information from the cell or row was clicked.

Hi @geral

Sure, you can use the getDataAtRow() method.

Here's an example: http://jsfiddle.net/prq8nxbv/
In this example I'm logging data via afterSelection callback but you can also add the same code to afterChange hook as well.

Thanks @aleksandra_budnik this helps a lot, one last question, instead getting the value has you show just not, is it possible to get the value when i click inside the cell and than clicked out?Basically just for you to better understand my issue, i need to get the value of a specific row, but then i need to check if that value was changed by the user.

To track if cell was changed you can use the afterChange hook. Here's the updated demo: http://jsfiddle.net/Lc0sk46g/

I'm logging the row data only if the change wasn't made via loadData. You can add more exceptions like to log the data only when the cell was edited

if(changes === 'edit')

or when new value of the cell is different from the one that was before

if(src[0][2] !== src[0][3])

ps. if you would like yo block a change then it's recommended to choose 'beforeChange' hook.

if(src[0][2] !== src[0][3])

hello @aleksandra_budnik this "if(src[0][2] !== src[0][3])" was great, helps a lot it was exactlly what i was looking for, only last question, i tried to get the entire row after and before using var before = this.getDataAtRow(src[0][2]);
var after = this.getDataAtRow(src[0][3]);

But i guess doesnt work this way

[aleksandra_budnik]

That's right @geral it doesn't works that way

As a quick tip

src[0][0] - this is a row of changed cell 
src[0][1] - this is a column of changed cell 
src[0][2] - this is an old value
src[0][3] - this is a new value

while the getDataAtRow() method takes only one argument, which is a row index.

if you would like to get an array of data with old value, you can use beforeChange hook. Here's an example: http://jsfiddle.net/bdm91eke/

I'm declaring the old variable and in the beforeChange hook I'm filling it with the data from getDataAtRow. At the end I'm logging both tables via afterChange hook.
