The path that generates the action="undefined" value is this:

JavaScript
var value_1_2 = d3.select(this).property("market");
document.querySelector('#botao-de-jogo-betfair-1').action = value_1_2;


CSV file "Lista_de_Jogos.csv" is:

label,value,market
,,
house,car,work


The selection box perfectly shows both attributes:

HTML
<option value="car" market="work">house</option>


But when I select this , instead of action of #botao-de-jogo-betfair-1 keep the value work he gets the value undefined:


HTML
<form id="botao-de-jogo-betfair-1" action="undefined" target="_blank">
					<input type="submit" style="width: 100%;" value="Jogo Betfair 1">
				</form>


Note: when I try to use .property("value") returns the value car perfectly.

What I have tried:

JavaScript
<script src="https://d3js.org/d3.v4.js"></script>
<script id="script-da-caixa-de-selecao-suspensa-1">
	var select_1 = d3.select("#caixa-suspensa-1")
	.append("select")
	.attr("id","select-box-1")
	.style("width","100%");
	
	function caixa_suspensa_1(data) {
	select_1
		.on("change", function(d) {
		var value_1 = d3.select(this).property("value");
		document.querySelector('#barra-de-texto-para-radar-1').value = value_1;
		document.getElementById('botao-do-radar-1').click();
		var value_1_2 = d3.select(this).property("market");
		document.querySelector('#botao-de-jogo-betfair-1').action = value_1_2;
		});
	let update_1 = select_1.selectAll("option")
		.data(data);
	update_1.exit().remove();
	update_1.enter().append("option").merge(update_1)
		.attr("value", d => d.value)
		.attr("market", d => d.market)
		.text(d => d.label);
	}
	d3.csv("Lista_de_Jogos.csv", function(data){caixa_suspensa_1(data)});
</script>
