How To Dynamically Add "More" Option To Rows

How To Dynamically Add "More" Option To Rows

I came across this post http://datatables.net/forums/discussion/17590/adding-a-button-per-each-row-with-mouseover-event-adding-click-event-on-button/p1 while trying to put a "More..." button on the row that would reveal more detail about the row. As with the OP, I can't determine when the option is clicked!

Currently, I'm able to double click the row to toggle the details for the row, but, I'd prefer to have a visual clue like "More..." to trigger this action.

The issue got closed and I can't find any way to resolve it.

I'll update this post with a jsFiddle once I can produce the issue. Just thought that if the solution is a simple one, perhaps the jsFiddle isn't even required.

    jsFiddle http://jsfiddle.net/knVrQ/1/

    Move mouse pointer over rows and try to click the button. No alert is given.

    You want to use `mouseenter` rather than `mouseover` : http://jsfiddle.net/knVrQ/2/

    The problem with `mouseover` is that it fires every time you mouse over a child element of the target as well (cells, and the button in this case) which disrupts things badly. Its also a performance hit. `mouseenter` (and `mouseleave` ) are much nicer.

    Thanks for that explanation Allan, however, the jsfiddle that you've modified to use mouseenter still does not react to the click event of the "Add" button.

    UPDATE: The alert sometimes appears but it seems random when it does. I don't have any sequence of events to give. All that I could determine is that if I keep clicking the button or the actual row and then try different rows, eventually sometimes the alert is shown.

    Seems to work 100% of the time fore.

    I would say that your code is making the HTML invalid since it is adding a button to a `tr` element. Perhaps that effects some browsers...

    You are correct. It seems to only be a problem in Chrome (my default browser). IE and Opera just check out fine. Not sure of others.

    Thanks again for your help.
