Question

I have a problem I want to change the length of string. This is my string of characters that I want to change.

Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim .

I use substring function in javascript but the outputs is not like I need.
this is my code

var str="Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ";
document.write(str.substring(100)+"<br />");

but the output is like this

laoreet dolore magna aliquam erat volutpat. Ut wisi enim 

My goal is just to make the length of that string of character to be 100 starting from the first character.

how i can solve this…thanks for your answer

Answer 1

It appears english is a second language for you and your question is very unclear. But based on what you posted I am guessing you want to truncate a string. This is straightforward using javascript’s string methods.

//example of truncating a string based on # of characters
var foo = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim."
var bar = foo.substring(0, 100);

//if you want to truncate at a particular word then use indexOf to find it in orig string
var banana = foo.substring(0, foo.indexOf('tincidunt'));
