appears text when mouse is over D3

Question

Hi everyone I am using sunburst of D3.js I want to include a text element inside each element.

For that my code is like this

var path = g.append("path");

if (data_key != "used"){
  svg.selectAll("g").append("text")
    .attr("dx", function(d){return -50})
    .attr("dy", function(d){return 20})
    .attr("class", "all_users")
    .style("display", "none")
    .text("text");
}

and it works my structure is like this

<g>
<path style="stroke: rgb(255, 255, 255); stroke-width: 1; fill: transparent; opacity: 0.3;" d="M0,63.58917920822171A63.58917920822171,63.58917920822171 0 1,1 0,-63.58917920822171A63.58917920822171,63.58917920822171 0 1,1 0,63.58917920822171Z"></path>
<text dx="-50" dy="20" class="all_users" style="display: none;">text</text>
</g>

I add display none to my text style, and I want to change the style (appears the text when the mouse is over this path)

for that purpose I use this

var g = gs.enter().append("g")
      .on("mouseover", mostrar)

like this

  function mostrar(d){
    ...
      $(this).closest('text').css("display", "inherit");

  }

but this $(this).closest('text') return an empty array [] . Any idea how to get the text when my mouse is over this part of the plot.

Thanks in advances

First of all: this mix of D3 and jQuery is definitely not the best practice.

That being said, you can easily get the hovered element with this , and select the text with a simple selection. After that, set the style with style

d3.select(this).select("text").style("display", "inherit");

Here is a demo with your paths and texts:

 var g = d3.selectAll("g"); g.on("mouseover", show).on("mouseout", hide); function show() { d3.select(this).select("text").style("display", "inherit"); } function hide() { d3.select(this).select("text").style("display", "none"); }
