How Can I Truncate A String In jQuery?

From:
jQuery text truncation (read more style)

Try this:

var title = "This is your title";

var shortText = jQuery.trim(title).substring(0, 10)
    .split(" ").slice(0, -1).join(" ") + "...";

• Tested here

And you can also use a plugin:

• jQuery Expander Plugin

As a extension of String

String.prototype.trimToLength = function(m) {
  return (this.length > m) 
    ? jQuery.trim(this).substring(0, m).split(" ").slice(0, -1).join(" ") + "..."
    : this;
};

Use as

"This is your title".trimToLength(10);
