Remove Part String Javascript Informing the End

Question

I have the following javascript function:

var opts = document.getElementById('id_endereco'); //localiza select
var str = opts.options[opts.selectedIndex].innerText; //Pega text do option

I need to remove part of the content from select, 'str', this value is variable, but I have a fixed word in all options, the word 'Address: '. I need to remove this word including everything that comes before it.

I tried to:

var resultado_str = str.replace(0, str.indexOf("Endereço: ") + 1, "");
document.getElementById('endereco_correto').value = resultado_str;

But it didn’t work.

Answer 1

I made a combination of substring with the indexOf, I get which index the "Endereço: " and we add to this index the number of characters that this text has, in case 10.

var str = "texto antes Endereço: Da minha casa";
var textoReplace = "Endereço: ";
var resultado_str = str.substring(str.indexOf(textoReplace) + textoReplace.length); // essa soma da 22

"Of my house"

Your problem with using indexOf is that it will return the first position of the informed text and not the last as you are expecting.

Your final code will be:

var textoReplace = "Endereço: ";
var opts = document.getElementById('id_endereco'); //localiza select
var str = opts.options[opts.selectedIndex].innerText; //Pega text do option

var resultado_str = str.substring(str.indexOf(textoReplace) + textoReplace.length);
document.getElementById('endereco_correto').value = resultado_str;
