How Can I Truncate A String In jQuery?

I have long titles and want truncate them but in a way that no words break, I mean the cutting happen between words not cutting a word.

How can I do it using jquer开发者_高级运维y?

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);

The solution above won't work if the original string has no spaces.

Try this:

var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10)
                          .trim(this) + "...";

  function truncateString(str, length) {
     return str.length > length ? str.substring(0, length - 3) + '...' : str
  }

Instead of using jQuery, use css property text-overflow:ellipsis. It will automatically truncate the string.

.truncated { display:inline-block; 
             max-width:100px; 
             overflow:hidden; 
             text-overflow:ellipsis; 
             white-space:nowrap; 
           }

with prototype and without space :

 String.prototype.trimToLength = function (trimLenght) {
    return this.length > trimLenght ? this.substring(0, trimLenght - 3) + '...' : this
};
