You can do something like this: $(‘#searchString’).keyup(function(e) { clearTimeout($.data(this, ‘timer’)); if (e.keyCode == 13) search(true); else $(this).data(‘timer’, setTimeout(search, 500)); }); function search(force) { var existingString = $(“#searchString”).val(); if (!force && existingString.length < 3) return; //wasn’t enter, not > 2 char $.get(‘/Tracker/Search/’ + existingString, function(data) { $(‘div#results’).html(data); $(‘#results’).show(); }); } What this does is perform a … Read more

You’ll have to filter out the elements after the event and not in the selector, like this $(document).on(‘keypress’, function(e) { var tag = e.target.tagName.toLowerCase(); if ( e.which === 119 && tag != ‘input’ && tag != ‘textarea’) doSomething(); }); this checks the tagname of the event.target, the element the event originated from, and only fires … Read more

For the QLineEdit connect to the returnPressed signal.
