put the value back in the input (Beginner)

[tlob]

Hello

I managed to do sucessfully:

$(document).ready(function(){
        $("#schnellsuche input").focus(function () {
                        $(this).val("");
        });
});


<form action="" id="schnellsuche">
<input class="text" type="text" value="Schnellsuche" />
</form>

I'm so proud of me ;-)

now I want the default value back in, when the focus is not anymore in
the input textbox. Can someone put me in the right direction?

thx

 From memory (so it might need tweaking....) you need to chain another
event to your code up there:

$(document).ready(function(){
        $("#schnellsuche input").focus(function () {
  $(this).val("");
  }).blur(function() {
                if ($(this).val() == "") {
                        $(this).val($(this)[0].defaultValue);
                }
        });
});

This adds a blur event that says if the value is empty, restore it to
the element's default value.

Hope this helps. :)

works like a charm!

but I dont get it...
-blur is the opposite of focus, right?
-why do you chain it after the focus?
-with [0].defaultValue you restore the first value that was stored in
an array?
-does JS store every changed value of every element in an array?

thx a lot!

Excellent :)

Yep - focus is triggered when the user tabs or clicks into the input -
blur is triggered when they tab or click out of it so it's no longer the
active element.

'tis the jQuery way! What we're basically doing is saying "with the
input in #schnellsuche, add a focus handler, then add a blur handler".

Not quite. If you imagine $(this) as an array of DOM objects within
jQuery, then $(this)[0] is a way to access the first (or in this case,
only) DOM object. jQuery doesn't have a built in way to retrieve the
default value of an input, so we have to nip back into the DOM
momentarily in order to retrieve it.

The DOM contains a defaultValue attribute for every text input, textarea
and select box. Not sure about checkboxes and radio buttons.

I invite other people to clear up any parts of my reply which aren't
totally accurate (you can tell I have faith in my ability to explain
things properly, I must say this in every post!)

Hey,

I extended your example code to add a blur function.  You can add an
if statement in the blur function if you need to restore the default
only in certain cases (like only if $(this).val() == "")

$(document).ready(function(){
        $("#schnellsuche input")
             .focus(function () {
                    $(this).val("");
             })
             .blur(function() {
                    $(this).val("Schnellsuche");
             });


});

$('#ANinputID').attr('defaultValue') works in my IE :)
