How to set Javascript's variable value inside <input value=''">
Question
I do not know how to formulate this question but it is near close to my issue. I am trying to make a Point of sale system so when client clicks in each product it adds in the table. There are no issues in my code but I do not know how to set the product's price using a textbox when using .append .
This is my code:
$(".agregarListaF").click(function (e) {
e.preventDefault();
var padre = $(this);
var hijos = padre.children().children("span");
var i = 0;
var datos = new Array();
hijos.each(function () {
switch (i) {
case 0:
datos[0] = $(this).text();
break;
case 1:
padre;
datos[1] = $(this).text();
break;
case 2:
padre;
datos[2] = $(this).text();
break;
}
i++;
});
console.log(datos[0]);
console.log(datos[1]);
$(".detallefactura").append(
"<tr>" +
"<td>" +
datos[0] +
"</td>" +
"<td>" +
datos[1] +
"</td>" +
"<td>" +
"<input type='text' class='form-control text-center' value='1'>" +
"</td>" +
"<td>" +
"<input type='text' class='form-control text-center' value=''>" +
"</td>" +
"<td class='tota-sub-fila'>" +
parseFloat(Math.floor(datos[2]) * parseFloat(1)).toFixed(2) +
"</td>"
);
});
My issue is in the line:
+ "<td>" + "<input type='text' class='form-control text-center' value=''>" + "</td>"
I want to add javascript value variable inside * input value=''* but I know It wont work but I tried it:
+ "<td>" + "<input type='text' class='form-control text-center' value='datos[2]'>" + "</td>"
This is my point of sale view:
In the column precio is where I want to set the price inside that textbox.
How do I solve this?

You can do:
var variable="x";
"<input type='text' class='form-control text-center' value='"+ variable +"'>";
Or,
`<input type='text' class='form-control text-center' value='${variable}'>`

Follow this using template literals
const html = `<tr>
<td>${datos[0]}</td>
<td>${datos[1]}</td>
<td><input type="text" class="form-control text-center" value="${datos[3]}"></td>
<td><input type="text" class="form-control text-center" value="${datos[4]}"</td>
<td class="tota-sub-fila">${parseFloat((Math.floor(datos[2])) * parseFloat(1)).toFixed(2)}</td>
</tr>`;
$(.detallefactura").append(html);

you can use Template literals like this instead of having this concatenation:
$(.detallefactura").append(`<tr>
<td> ${datos[0]} </td>
<td> ${datos[1]} </td>
<td> <input type='text' class='form-control text-center' value='1'> </td>
<td> <input type='text' class='form-control text-center' value='${datos[2]}'> </td>
<td class='tota-sub-fila'> ${parseFloat((Math.floor(datos[2])) * parseFloat(1)).toFixed(2)} </td>
`);
