I used this to achieve the required

here 'description' is the id of the input html element

JavaScript

$('#description').keypress(function (e) {
               if (e.charCode == 32 && $(this).val()[$(this).val().length - 1] == ' ')
                   e.preventDefault();
           });

Hello,

You can do this either using JavaScript or Server side PHP. I am presenting here the JavaScript version. I am assuming that your textbox name is txtNotes & is declared as shown below.

HTML

<input type="text id="txtNotes" name="txtNotes" onChange="removeSpaces(this)"/>

The Javascript

JavaScript

function removeSpaces(ctrl)
{
    var ret = "";
    if (ctrl.value != null && ctrl.value.length > 0) {
        var parts = ctrl.value.split(" ");
        for (var i = 0; i < parts.length; i++) {
            var tmp = parts[i].replace(/^\s+|\s+$/g,'');
            if (tmp.length > 0) {
                ret += (tmp + " ");
            }
        }
        ctrl.value = ret.substring(0, ret.length - 1);
    }
}

Solution 2

You could do it with a regular expression, either in Javascript or PHP:

Javascript version:

JavaScript

function removeSpaces(ctrl)
{
  var s = ctrl.value;
  ctrl.value = s.replace(/\s+/g, ' ');
}

Tried it, It won't remove trailing spaces from input.

The OP didn't ask for removing trailing spaces, only for replacing double spaces with single.

But if you need that: ctrl.value = s.replace(/\s+/g, ' ').replace(/^\s+|\s+$/g, '');
