Realizing that this is a rather old post, I’ll provide an answer anyway as I was struggling with the same problem.
You should use the "input"
event instead, and register with the .on
method. This is fast – without the lag of keyup
and solves the missing latest keypress problem you describe.
$('#dSuggest').on("input", function() {
var dInput = this.value;
console.log(dInput);
$(".dDimension:contains('" + dInput + "')").css("display","block");
});
