Add the following code in WordPress theme functions.php:

class widget_test extends WP_Widget {
    function widget_test () {
        $ Widget_ops = array ('description' => 'description of the small tools');
        $ This-> WP_Widget ('widget_test', 'the title of the gadget', $ widget_ops);
    }
    function widget ($ args, $ instance) {
        extract ($ args);
        $ Title = apply_filters ('widget_title', esc_attr ($ instance ['title']));
        $ Limit = strip_tags ($ instance ['limit']);
        echo $ before_widget. $ before_title. $ title. $ after_title;
        echo '<ul class="middleli">';
            test ($ limit); / / function to be executed gadget
        echo '</ ul>';
        echo $ after_widget;
    }
    function update ($ new_instance, $ old_instance) {
        if (! isset ($ new_instance ['submit'])) {
            return false;
        }
        $ Instance = $ old_instance;
        $ Instance ['title'] = strip_tags ($ new_instance ['title']);
        $ Instance ['limit'] = strip_tags ($ new_instance ['limit']);
        return $ instance;
    }
    function form ($ instance) {
        global $ wpdb;
        $ Instance = wp_parse_args ((array) $ instance, array ('title' =>'', 'limit' =>''));
        $ Title = esc_attr ($ instance ['title']);
        $ Limit = strip_tags ($ instance ['limit']);
?>
        <p>
            <Label for = "<? Php echo $ this-> get_field_id ('title');?>"> Title: <input class = "widefat" id = "<? Php echo $ this-> get_field_id ('title') ;?> "name =" <? php echo $ this-> get_field_name ('title');?> "type =" text "value =" <? php echo $ title;?> "/> </ label>
        </ P>
        <p>
            <Label for = "<? Php echo $ this-> get_field_id ('limit');?>"> Quantity: <input class = "widefat" id = "<? Php echo $ this-> get_field_id ('limit') ;?> "name =" <? php echo $ this-> get_field_name ('limit');?> "type =" text "value =" <? php echo $ limit;?> "/> </ label>
        </ P>
        <Input type = "hidden" id = "<? Php echo $ this-> get_field_id ('submit');?>" Name = "<? Php echo $ this-> get_field_name ('submit');?>" Value = "1" />
<? Php
    }
}
add_action ('widgets_init', 'widget_test_init');
function widget_test_init () {
    register_widget ('widget_test');
}

Is the way to go after saving gadget in your look, is not more than one called "the gadget title of" the gadget you? Noted that the code above test ($ limit); this is a small tool you need to perform the function, you can write in here, you can also write to functions.php in function, are the same.

<script type="text/javascript">
function addLink() {
    var body_element = document.getElementsByTagName('body')[0];
    var selection;
    selection = window.getSelection();
    var pagelink = " Add your Copyright text here!";
    var copytext = selection + pagelink;
    var newdiv = document.createElement('div');
    newdiv.style.position='absolute';
    newdiv.style.left='-99999px';
    body_element.appendChild(newdiv);
    newdiv.innerHTML = copytext;
    selection.selectAllChildren(newdiv);
    window.setTimeout(function() {
        body_element.removeChild(newdiv);
    },0);
}
document.oncopy = addLink;
</script>

From now on everyone that try to copy your content and paste the content on text editor new copyright notices will be follow

<div class="test1">
<! – Style = "display: none ;"—- style.css ->
<span> *****</ span>
<span style="display:none;"> *****</ span>
<span style="display:none;"> *****</ span>
<p id="prev"> «</ p>
<p id="next"> »</ p>
</ div>

Second, jQuery code sections (more complex than before, but the results always have to sacrifice points to Well)

jQuery (document). ready (function () {/ / jQuery information on the rotation effect by zwwooooo
    $ ('# prev'). click (function () {
    $ ('. test1 span: visible'). fadeOut ('fast',
    function () {
    if ($ (this). prev (). is ('span')) {
    $ (this). prev (). fadeIn ('fast');
    } Else {
    $ (". test1 span: last"). fadeIn ('fast');
    }
    });
    });
    $ ('# next'). click (function () {
    $ ('. test1 span: visible'). fadeOut ('fast',
    function () {
    if ($ (this). next (). is ('span')) {
    $ (this). next (). fadeIn ('fast');
    } Else {
    $ ('. test1 span: first'). fadeIn ('fast');
    }
    });
    });
    var b,
    a = function () {
    $ ('# next'). trigger ('click'); / / copy click time
    b = setTimeout (a, 5000); / / 5 秒 rotation, the same
    };
    $ ('. test1'). hover (function (){// when the mouse hovers
    clearTimeout (b); / / stop the rotation
    }
    function () {
    b = setTimeout (a, 5000);
    });
    b = setTimeout (a, 5000);
});

<div class="test">
	<strong>&raquo;</strong><!-- style="display:none;"style.css -->
	<span style="display:none;">text text text  </span>
	<span style="display:none;">text text </span>
	<span style="display:none;">text </span>
</div>

2. JQuery code, specifically to see comments

jQuery(document).ready(function(){
	test(); 
	setInterval('test()', 6100); 
});
var test_i = 0, 
	test_span_arr = 0;
	test_span_num = 0; 
function test() {
	if(test_span_arr==0){
	test_span_arr = $(".test").children("span");
	test_span_num = test_span_arr.length - 1; 
	}
	if (test_i > test_span_num) {test_i = 0;} 
	$('.test span:eq('+test_i+')').fadeIn(1500); 
	setTimeout(function() {$('.test span:eq('+test_i+')').fadeOut(1500);test_i++;},4500);
};

Analysis: For instance, catalog has the function to obtain id from catalog name (not slug), which is get_cat_ID, then we can create a function as follows:

function get_page_id($page_name){
    global $wpdb;
    $page_name = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_name = '".$page_name."' AND post_status = 'publish' AND post_type = 'page'");
    return $page_name;
}
