javascript - Selecting Elements in d3 after (this) -

-

In D3 I am animate those elements that they are. 

  .on ('mouseover', function (d, i) {d3.selectAll ('rect') .attr ('y', function () {// all & lt; rect & Gt; Elements affect / if I have tried (source.length> (I + 1)) {console.log (i);}} d3.select (this) .attr ('y' Function (// only affects mouseover element) // did not work from above, maybe there would be some other selection method? D. 3. Detect (Altitude Afrothis) .attr ('y' function () {// Some other values }}

I have a

d3.selectAll ('rect')

D3 .select (this)

What do I want to know That is to select only the elements after the group in this . 

  context 1 -> select all rect 2 -> .select all Rect 3 -> this React 4 -> How do I target it? Rect 5 -> or this particular?

You can do this: 

 On  ("mouseover", function () {var node = this; while (node ​​= node . Newcast Sibling) {d3.select (node) ...;}})
