jquery - How do I set the character limit for .load -

i'm pulling in body of text page, want limit amount of characters .load event pulls. how control amount of characters pulled class ".paragraph"?

here have far:

$("document").ready(function(){        // blog descriptions     $( ".blog-description-3" ).load( "/blog.html .blog-post:nth-of-type(3) .blog-content .paragraph"); }); 

you can't limit number of characters method pulls in. can manipulate returned string , cut needs substr()

$(".blog-description-3").load("/blog.html .blog-post:nth-of-type(3) .blog-content .paragraph", function() {     var txt = $(".blog-description-3").text().substr(0, 20);     $(".blog-description-3").text(txt); });
