Hi Ovilia,
many thanks for your mail.
I am not a javascript specialist ... (I juste "copy" and "paste" :-])
But suppose that you have the code as is in echarts manual. (see below).
It exist many "orange" entries.
How can I have a search zone like this :
<div id="footer">
<label for="search">search: </label>
<input type="text" id="search" onkeyup="update(this.value)">
</div>
and a function like this :
/** Updates the visualization and count when a new query is entered. */
function update(query) {
if (query != re) {
re = new RegExp(query, "i");
count();
vis.render();
}
and when I write "orange" in search zone
the fonction update search (with RegEx or other solution) the chain "orange"
for all nodes and
show more or less brilliant the nodes that contain "orange" as name.
Best regards
Pier Luigi

Objet: Re: Select nodes and childrens by search javascript function (RegExp) in
a treemap graph
Hi Pier,
You can set the color of each block with [1] and on search text change, you
should
call `setOption` with the calculated color to update the chart.
Thanks
Ovilia
