What is the best way to match both uppercase and lowercase letters in AngularJS?

I need help crafting a regular expression to match all uppercase and lowercase letters in my code. Currently, I am only able to match specific characters, but I want to match all characters regardless of case. Here is the excerpt from my code:

$scope.set_color = function(row) {
    var inputString = row.Subject;
    for (i = 0; i < inputString.length; i++) {
        //var findme = "HOT RUSH";
        //var str = findme.match(/\b([a-z][A-Z])\b/);
        var findmeCap = "HOT RUSH";
        var findmeSmall = "hot rush";
        if (inputString.indexOf(findmeCap) > -1 || inputString.indexOf(findmeSmall) > -1) {
            return {
                'background-color': '#FFCCCB'
            }
        }
    }
}

Can anyone provide guidance on how to achieve this?

Answer №1

To compare two strings, you can use the functions string.toUpperCase() and string.toLowerCase(). Then, based on the comparison result, you can change the color accordingly.

var a = "hello";
var b = "HELLO";  
if (a.toUpperCase() === b.toUpperCase()) {
   alert("The strings are equal");
   //Change color 
}

You have the flexibility to choose any of these methods for comparing strings in your code.

let userInput = rowData.Description;
let searchTerm = "spicy chill";
if(userInput.toLowerCase().includes(searchTerm)) {
  return {'background-color': '#FFCCCB'};
}

This is my suggested approach for tackling the issue. Regular expressions are unnecessary in this case, and looping through the data can be avoided.

                           var keyword = "important note";
                           if (textToHighlight.toLowerCase().indexOf(keyword) > -1) {
