Put a Javascript variable into a innerHTML code

Question

I'm creating a table dynamic table with Javascript:

var row = table.insertRow(-1);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
var cell5 = row.insertCell(4);

I want to fill the cell5 with some innerHTML with a Javascript variable inside

var add = aux[i].split("#");
cell5.innerHTML = "<img src='MatrixLogos/add[3]' width='100' height='25'/>";

but this give add[3] in the html instead of the value inside add[3].

My question is how to escape the variable inside the innerHTML code, so it shows me is value and not the declaration.

There's currently no syntax for string interpolation. You can create a method that defines such behavior for strings, or you can simply concatenate the values in. — user1106925

Use "+".

var add = aux[i].split("#");
cell5.innerHTML = "<img src='MatrixLogos/"+add[3]+"' width='100' height='25'/>";

What if the value is saying undefined but after logging the variable in console we can see the result

Use String concatenation like

var add = aux[i].split("#");
var string = "This is to " + add[3] + " test with value";

Where as in your case, statement will become:

cell5.innerHTML = "<img src='MatrixLogos/"+add[3]+"' width='100' height='25'/>";
