javascript - 将指定字符转换为大写

Question

是否可以将每个“_”登录后的下一个字符转换为大写？

例如:

var myString = "Taylor_swift";
var rg = /(_)/gi;
myString = myString.replace(rg, function(toReplace) {
    $("#textField").val( toReplace.toUpperCase() );
});

Answer 1

你可以试试

var myString = "Taylor_swift";
var rg = /_(.)/gi;
myString = myString.replace(rg, function(match, toReplace) {
  return ' ' + toReplace.toUpperCase();
});
console.log(myString);
$('#result').html(myString)

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="result"></div>
