I wanted to make a syntax highlighter that highlights symbols. Look at the example:
function hello(){
return "hello";
}
I want to highlight all the symbols:
{([</!&|\>])};.,:=+*-@$~_^?%'"
And I made a little one that highlighted strings. When I wanted to make one that highlights symbols I got confused. Now I want to know What topics should I learn to make it? Any example, github repo, tutorial, topic or ...? EDIT: I found the way to do that but I still have problem. My code is the following:
function syntaxue(){
var codes = document.getElementsByClassName("syntaxue");
for (var i=0; i < codes.length; i++){
var data = codes[i].innerHTML;
data = data.replace(/([^\w\s&;])/g, '<span class="sym">$1</span>');
data = data.replace(/(<)/g, '<span class="sym">$1</span>');
data = data.replace(/(>)/g, '<span class="sym">$1</span>');
data = data.replace(/([\d])/g, '<span class="num">$1</span>');
codes[i].innerHTML = data;
}
}
When I want to highlight strings, the code becomes sth else.(Sorry I'm not English) And I was testing HTML markup I saw this:
<html>
Instead of this:
<html>
And the &; symbols were highlighted not their results. Can anyone help me?
