If I understand correctly you want to limit a string to 10 characters   var str    Some very long string   if str length  gt  10  str   str substring 0 10     Something like that

What you should also do when you truncate the string to ten characters is add the actual html ellipses entity   amp hellip   rather than three periods

And here s a jQuery example   HTML text field    lt input type  text  id  myTextfield    gt    jQuery code to limit its size   var elem       myTextfield    if elem  elem val elem val   substr 0 10      As an example  you could use the jQuery code above to restrict the user from entering more than 10 characters while he s typing  the following code snippet does exactly this     document  ready function         var elem       myTextfield        if  elem            elem keydown function                 if  elem val   length  gt  10                  elem val elem val   substr 0  10                                          Update  The above code snippet was only used to show an example usage    The following code snippet will handle you issue with the DIV element     document  ready function         var elem       tasks-overflow        if elem           if  elem text   length  gt  10                  elem text elem text   substr 0 10               Please note that I m using text instead of val in this case  since the val method doesn t seem to work with the DIV element

jolly exe   Nice example Jolly   I updated your version which limits the character length as opposed to the number of words   I also added setting the title to the real original innerHTML   so users can hover and see what is truncated    HTML   lt div id  stuff  gt a reallly really really long titleasdfasdfasdfasdfasdfasdfasdfadsf lt  div gt     JS   function cutString id            var text   document getElementById id  innerHTML                var charsToCutTo   30          if text length gt charsToCutTo               var strShort                   for i   0  i  lt  charsToCutTo  i                     strShort    text i                             document getElementById id  title    text               document getElementById id  innerHTML   strShort                                         cutString  stuff

This looks more to me like what you probably want     document  ready function    var stringWithShorterURLs   getReplacementString     tasks-overflow   text      function getReplacementString str       return str replace   https          s    gi function match           return match substring 0 10                          you give it your html element in the first line and then it takes the whole text  replaces urls with 10 character long versions and returns it to you  This seems a little strange to only have 3 of the url characters so I would recommend this if possible     document  ready function    var stringWithShorterURLs   getReplacementString     tasks-overflow p   text      function getReplacementString str       return str replace  https           s    gi function match           return match substring 0 10                         which would rip out the http    or https    and print up to 10 charaters of www example com

Although this won t limit the string to exactly 10 characters  why not let the browser do the work for you with CSS    no-overflow       white-space  no-wrap      text-overflow  ellipsis      overflow  hidden      and then for the table cell that contains the string add the above class and set the maximum permitted width   The result should end up looking better than anything done based on measuring the string length
