How to detect hashtag and @ with Expressions
Hi,
I was wondering if it’s possible to detect a hashtag or @ and automatically change the color?I’m a javascript developer and I found a way to detect hashtag and @ but I don’t know how to change the color then…
Look at this picture:
Thank you,

string.replace(/(^|\s)(#[a-z\d-]+)/ig, "$1$2 ") -

Someone might reply with a more modern method if it exists.
But if you put a fill color using the Animate button to the right when you drop down the text layer, then add an expression selector onto it. Something like this will work
words = text.sourceText.replace(/^\s+/, “”).split(/\s+/);
if (words[textIndex-1].indexOf (“#”) >-1) 100 else 0 -
Thank you, it works well!
Different subject but do you know if there’s a way to detect a specific sentence then also change the color?Example:
“Welcome on [start:color]Creativecow.net Jeremy[end:color], I hope you’re enjoying your day.”Thank you

Stealing this one from Dan Ebberts in another post. All you need to do is put a “[” at the front of the string and “]” at the end. Anything inbetween will be filled.
Put this into your sourceText
str = text.sourceText;
zws = “\u200b”;
res1 = str.replace(/\[/g, zws);
res2 = res1.replace(/\]/g, zws);and this into the expression selector, make sure to change Based on to Characters
txt = text.sourceText;
zws = “\u200b”;
idx = 1;
i = 0;
n = 0;
while (idx < textIndex){
if (txt.value[i] == “\r”){
i++;
continue;
}
if (txt.value[i] == zws) n++;
i++;
idx++;
}
n%2 ? 100 : 0 -
Thank you! Everything works very well!
