live preview of input form value

[Annaccond]

I'm working on some small project and I have troubles exactly like here:
how-to-make-live-preview-based-on-information-entered-in-a-form

I have a form with input fields where is possible to write values (width, height, margin, padding, etc.). I want "live preview" of what I'm changing. I tried something like:

<script>
$("#width").live("hover", function () {
var valWidth = $(this).val();
$("#test").css( "width", $("#test").width(valWidth) ).change();
});
$("#height").live("hover", function () {
var valHeight = $(this).val();
$("#test").css( "height", $("#test").height(valHeight) ).change();
});

...
</script>

but it reset after choosing another input field. Any help will be appreciated.

If #width, #height,.. are associated with an input field (text) then the event you should be handling are the "change".
Assuming the "#test" element is used for the preview:

$("#width").live("change", function () {
var valWidth = parseInt($(this).val());
if(!isNaN(valWidth)){
$("#test").css( "width", valWidth);
}
});

Your script resets after choosing another input field because of the hover

Now it seems to work - thank you.

I used "hover" to show preview after putting new value in input field (without leaving this field). Is there any way to could do it (maybe onkeypress or something)?

onkeyup

With "onkeyup" instead of change it change but after pressing "enter" but not in real time of writing changes.

<form id="div_builder">
   <input type="text" id="width"/>
   <input type="text" id="height"/>
   </form>
<div id="test" style="background-color:red">hello</div>

<script type="text/javascript">
$("#width").keyup(function () {
var valWidth = Number($(this).val());
if(!isNaN(valWidth)){
$("#test").css( "width", valWidth);
}
});

$("#height").keyup (function () {
var valHeight = Number($(this).val());
if(!isNaN(valHeight)){
$("#test").css( "height", valHeight);
}
});
</script>

It works partially (only for first "width" input). Any suggestions?

EDIT:

Got the error - I had default value in my input. Everything works as it should after removing it. Thank you!

you're welcome. if you want to cut down on repetition...

<form id="div_builder">
   <input type="text" class="changeD" id="width"/>
   <input type="text" class="changeD" id="height"/>
   </form>
<div id="test" style="background-color:red">hello</div>

<script type="text/javascript">
$(".changeD").keyup (function () {
var theval = Number($(this).val());
if(!isNaN(theval)){
$("#test").css( this.id, theval);
}
});
</script>
