Hello everyone, I am going to share the special characters validation using JavaScript/jQuery.
The input special characters  [email protected]#$%^&*()_+~{}[]';:"/.,<>?

Example as given below

$(function () {
   $("form :input[type='text']").on("keyup", function (e) {
        var inputTextId = $('#' + this.id);
        var inputText = inputTextId.val();

        var errorFor = this.id;
        if (!isValidChar(inputText)) {
            $('#' + this.id).val('').valid();       
            setTimeout(function () { replaceErrorMsg(errorFor); }, 100);
        }
    }); 
}); 

function isValidChar(str) {
    return !/[~`!#$%\^&*+=\-\[\]\\';,/{}|\\":<>\?]/g.test(str);
