Javascript select table row values

mwdbhyat — Fri, 17 May 2019 12:59:50 GMT

Hi there,

How would I select an entire row in a table from a dashboard and use each field/cell from that table to populate another panel/table when selected? Essentially just cloning whatever rows i select from one panel -> hit submit -> selected rows go to another panel.

Any thoughts on how to achieve this?

Thanks!

You are lucky. I'm working on the same for another purpose but I'm sure you will achieve the same by using the below code.

Note: This code is now Specific to index=_internal | stats count by sourcetype | eval recNumber=1 | accum recNumber | table recNumber sourcetype count - this - search. So you have to manual change for your search. In your search you have to add | eval recNumber=1 | accum recNumber and put this as checkbox column. find recNumber in javascript which will let you know at how many places you have to make changes. Another field is sourcetype, this will also help you.

@kamlesh_vaghela awesome stuff this is really cool! Thanks! Do you have any tricks up your sleeve to send a sparkline across from table 1 to table 2 =D ..i have some timechart sparkline graphs in table 1 and in table 2 they are just the numerical values..
