I am facing a challenge with a JavaScript string that contains contact information that needs to be filtered. For example, I want to mask any email or phone number in the message.
I have attempted the following approach:
function(filterMessage) {
var maskedMessage = filterMessage.replace("/^([\da-z_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/", "<MaskedEmail>");
return maskedMessage;
}
Unfortunately, this method is not producing the desired results.
Give this a shot:
function sanitizeEmail(message) {
var m = message.replace(/[\da-z_\.-]+@[\da-z\.-]+\.[a-z\.]{2,6}/, "<Email>");
return m;
}
alert(sanitizeEmail("Your Email: <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="39827e93878b8c978687808fce85889386">[email protected]</a> lorem Ipsum dolor"));
See the demo here: http://jsfiddle.net/abcd1234/
Issues to address in your code:
I like to employ a more lenient regex pattern when searching for email addresses because of the various formats they can take. One example you could try is:
/\S+@\S+\.\S+/
This regex will match [email protected], where any non-whitespace characters can be used instead of a, b, and c.
Feel free to use this alternative regex in place of the one suggested by strah's recent answer.
Give this a shot:
function modifyText(text) {
//var reg = /^([\da-z_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/;
var regExp = /\b(\S+@\S+\.\S+)\b/g;
var modifiedText = text.replace(regExp, "<Email>");
return modifiedText;
}
modifyText("email.example.com will be substituted, and so will be <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="98f6fde0ecd8fde0f9f5e8f4fdb6fbf7f5">[email protected]</a>");
Alternatively, you can try using this regular expression: /\b(\S+@\S+\.\S+)\b/g (taken from Kieran Pot's response) and then apply your function for more accurate filtering.
