Javascript for replacing an abreviation by his equivalent

Question

I met some trouble with a javascript.

In fact I have in my database many records that are abreviations and ther equivalent,

for example, replace tel => telephon

Answer 1

When using keypress this way the code variable will contain the character code of the pressed character. Not the string of chars like the expected 'tel'. You could use onkeyup / onchange event and check the val() of the input element and use replace() to change the abbreviation to the intended string.

$('#tags').keyup(function(e){

    var elem = $(this);
        var input = elem.val();

        // input = input.substr(0, input.length -1);  // This might not be necessary
        console.log(input);

        // do the replacement
        input = input.replace('tel','telephone');

        elem.val(input);        
    }

});
