I am working on a small webpage that formats the text you input, for a Minecraft server I am involved in. The text is then meant to be copied to a discord channel. The problem is Discord's formatting which allows some characters can make the text underlined or bold. Some Minecraft usernames have underscored, and I wanted to make a loop that adds "" in front of any underscores so discord ignores them. This is what I came up with:
// example for result
var result = "__MinecraftUsername__";
// the loop
while (result.includes("_") == true) {
result = i(result, result.indexOf("_"), "\");
}
// in the actual code this is put into the html
alert(result);
// function to add characters at a specific index
function i(str, index, value) {
return str.substr(0, index) + value + str.substr(index);
}Try using a javascript function like the one in this example... that will eliminate the while loop.
But as a suggestion, why not wrap the minecraft names with back-quotes? That may preserve the name's characters, without trying to treat them as markdown codes. As an example of wrapping with back-quotes preserves the characters that would normally be treated as markdown: __some_*minecraft*_name__.
I'm using jQuery just to display the results, so you can ignore the jQuery.
var mcName = "_some_minecraft_name_";
$(".original").text(mcName);
var results = mcName.replaceAll("_", "\");
$(".sample").text(results);
/**

String.prototype.replaceAll = function( search, replace ) {
var results = this.split(search).join(replace);
return results;
