Question

This is my situation :

• I’m currently in the process of finalizing a rather… huge web application (PHP with CodeIgniter, MySQL, Javascript+Ajax+Jquery and using various Javascript libraries – e.g. dataTables)

The issue :

• Let’s say we’ve got a table, fixed-width.
• The first column is also fixed-width. (Let’s say at 200px)
• When the table is populated :
  • If the contents of the first column occupy less than 200px space, it’s ok.
  • If the contents exceed those 200px then the content is wrapped, thus creating a “double line” effect and higher rows than I’d wished.

Hint :

• “Shrinking” a very very very long line to something like very very very ... is what I’m thinking. Is something like that even possible? Server-side?

How would you approach that? (preferably in an elegant way – ‘coz, yep, I admit that I have a few solutions in mind, none of which seems… user-friendly… lol)

Answer 1

I think doing a string-truncation is impossible serverside, if you are not using a monospace font so that the same number of characters always has the same width. What you could do is a client-side string-truncation:

(Nice code at Calculate text width with JavaScript):

CSS:

#testing-div
{
    position: absolute;
    visibility: hidden;
    height: auto;
    width: auto;
}

JS:

var test = document.getElementById("testing-div");
test.style.fontSize = fontSize;
var height = (test.clientHeight + 1) + "px";
var width = (test.clientWidth + 1) + "px";

You can loop through the entire length of the string, and keep adding a character to the body of #testing-div, calculating the width, and checking if it fits. Make sure you add the ... if the string is too long.
