Helpers that prevent text from being displayed


User 3924026

This helper should look for hashtags and make them routes/links. Instead, it makes the text invisible. How can I fix this?

Here is the code:

handlebar.js

Handlebars.registerHelper('hashtag', function(posttext) {
    posttext.html();
    posttext = posttext.replace(/#(\w+)/g, "<a href='https://www.google.com/?q=$1' target='_blank'>$&</a>");
    posttext.html(posttext);
});

postidem.js

<h3 class="text">{{hashtag title}}</h3>
<p class="text">{{hashtag posttext}}</p>
Kuba Wyrobek

Try this:

Handlebars.registerHelper('hashtag', function(posttext) {
    // DEBUG START : just to know that `posttext` is really what you want; remove later;
    console.log("hashtag",posttext);
    // DEBUG END

    return posttext.replace(/#(\w+)/g, "<a href='https://www.google.com/?q=$1' target='_blank'>$&</a>");

});

notes:

  • Template.registerHelperWorks with Meteor 0.9.1 and above
  • Handlebars.registerHelperApplies to every edition.
  • Don't define global helpers in there, Meteor.startupas Blaze won't be able to find them.

Remember to put helpers in triple curly braces when returning HTML;

<h3 class="text">{{{hashtag title}}}</h3>
<p class="text">{{{hashtag posttext}}}</p>
