如何从文本中提取一个单词并将其链接？

Question

<script>
function myClick(){
text = "<b><i>this is my text, THIS NEEDS TO BE A HYPERLINK </i></b>";
document.getElementById('heading1').innerHTML  = document.getElementById('heading1').innerHTML + text;
document.getElementById("heading1").style.textAlign="left";
document.getElementById("heading1").style.marginLeft="5px";

}
</script>

I only want the capital letters to be a hyperlink, it seems really easy but i cant find an answer online. (-.-)

Answer 1

Something like this would do it

var text = "<b><i>this is my text, THIS NEEDS TO BE A HYPERLINK </i></b>";
// Regex matching only uppercase letters and whitespaces where there
// have to be at least 2 in a row to match
var match = text.match(/[A-Z\s]{2,}/);
if (match && match.length) {
  match.forEach(function (str) {
    text = text.replace(str, '<a href="http://google.com/q=regex">' + str + '</a>');
  });
}

EDIT: When you want to only replace a single word you can omit the \\s group in the regex: This regex still matches at minimum two uppercase characters to prevent misdetection of capitalized words or names.

    var match = text.match(/[A-Z]{2,}/);
