Question

noob here

i got this jquery code that i found on stackoverflow

    var maxLines = 2,
    maxLineWidth = 5;

$('#Users_address').bind('change keyup paste drop', function() {
   var value = $(this).val(),
       lines = value.split('\n'),
       linesLength = lines.length;

    if (linesLength > maxLines) {
       lines = lines.slice(0, maxLines);
       linesLength = maxLines;
    }

    for (var i = 0; i < linesLength; i++) {
        if (lines[i].length > maxLineWidth) {
          lines[i] = lines[i].substring(0, maxLineWidth);  
        } 
    }

    $(this).val(lines.join('\n'));
});

how would i use this with a text area??

Answer 1

Give your textarea an id:

<textarea id="Users_address"></textarea>

And load your script:

$(document).ready(function() {
    var maxLines = 2,
    maxLineWidth = 5;

    $('#Users_address').bind('change keyup paste drop', function() {
       var value = $(this).val(),
           lines = value.split('\n'),
           linesLength = lines.length;

        if (linesLength > maxLines) {
           lines = lines.slice(0, maxLines);
           linesLength = maxLines;
        }

        for (var i = 0; i < linesLength; i++) {
            if (lines[i].length > maxLineWidth) {
              lines[i] = lines[i].substring(0, maxLineWidth);  
            } 
        }

        $(this).val(lines.join('\n'));
    });
});
