I'm trying to change text color from a public website based on letter value. I don't own the web site so I have to use the console from developer tool. I was wondering what js script could be written in the console so the letters from a DNA sequence could be more easy to read like in this picture : https://www.researchgate.net/publication/2753662_New_Approaches_In_Mathematical_Biology_Information_Theory_And_Molecular_Machines/figures?lo=1
Example of code:
function changecolor(){
For each letters in page{
if letter = A then textcolor = red
elseif letter = T then textcolor = bleu
elseif letter = G then textcolor = green
elseif letter = C then textcolor = yellow
else textcolor = black
}
}
I don't know if it's possible to do such a task because there is more than a million character on this page
thanks for your time

CodePudding user response：
You can set opacity for every text element using this in CSS
color: rgba(0,0,0,0);
And to background set some rainbow image.
All this can be do in js.
Also this can help.

I finaly found how to change individual color of each letters based on the value of your charater: Javascript to change font colour based on value
Here is my code to put in the console:
var candidates = 'pre';
var candidateContainers = document.querySelectorAll(candidates);
var red = 'aA';
var ora = 'tT'
var blu = 'gG';
var pur = 'cC';
var all = red ora blu pur;
var char;
candidateContainers.forEach(function(entry) {
var str = entry.innerHTML;
var newStr = "";
for (var i = 0; i < str.length; i ) {
char = str.charAt(i);
if(all.indexOf(char) == -1){
// console.log("do nothing", char);
newStr = char;
}
if(red.indexOf(char) > -1){
newStr = wrapSpan('lightpink', char);
}
if(ora.indexOf(char) > -1){
newStr = wrapSpan('gold', char);
}
if(blu.indexOf(char) > -1){
newStr = wrapSpan('lightskyblue', char);
}
if(pur.indexOf(char) > -1){
newStr = wrapSpan('palegreen', char);
}
}
entry.innerHTML = newStr;
});
function wrapSpan(colour, char){
return '<span style="background-color: ' colour '">' char '</span>';
}
