Jquery Exclude a Selector?

I've got a form that I clear on focus. I've selected the whole form and it works great except that the submit button goes blank when I click it.

how can I exclude my input of input#submit from the following code?

    $(".wpcf7-form input, .wpcf7-form te开发者_运维技巧xtarea").focus(function() {
 if( this.value == this.defaultValue ) {
  this.value = "";
  $(this).addClass('filled');
 }
}).blur(function() {
 if( !this.value.length ) {
  this.value = this.defaultValue;
  $(this).removeClass('filled');
 }
});

Use the not selector to exclude what you want:

$(".wpcf7-form input:not('#submit_id'), .wpcf7-form textarea").focus(function() {
 // your code......
}

Or

$(".wpcf7-form input:not(input[type=submit]), .wpcf7-form textarea").focus(function() {
 // your code......
}

Use .not() to exclude your input button (or buttons) from the set of inputs you already have.

$('input.are.blong.to.us') // give me a bunch of inputs
    .not('#submit')        // exclude input#submit
    .focus( ... )          
    .blur( ... );

You want the not-equal to selector:

.wpcf7-form input[id!=submit]

or

.wpcf7-form input[type!=submit]

$(".wpcf7-form input:not(#submit), .wpcf7-form textarea")

not

You could use the css3-not selector.

A selector like that would be: input:not([type=submit]).
