嗨我已經安裝了這個小插件:jQuery插件調用方法
(function($) {
$.fn.tagfield = function(options) {
if (options && options.add) {
this.each(function(i, elem) {
add_tags(elem, options.add);
});
} if (options && options.remove) {
this.each(function(i, elem) {
remove_tags(elem, options.add);
});
} else {
this.each(function(i, elem) {
var initial_tags = $(elem).val();
$(elem).val('');
tagfield(this, $(elem));
$(initial_tags.split(',')).each(function(i, v) {
v = $.trim(v);
if (v !== '') add_tags(elem, v);
})
});
}
};
var KEYS = {
"enter": "\r".charCodeAt(0),
"space": " ".charCodeAt(0),
"comma": 188,
"backspace": 8
};
var tagfield_id_for = function(real_input) {
return $(real_input).attr('id') + '_tagfield';
};
var add_tags = function(real_input, text) {
remove_tags(real_input, text);
var tag = $('<span class="tag">').append('<span class="text">' + text +'</span>'),
close = $('<a class="close" href="#">X</a>');
close.click(function(e) {
remove_tags(real_input, text);
});
tag.append(close);
$('#' + tagfield_id_for(real_input) + " .tags").append(tag);
real_input = $(real_input);
real_input.val(($.trim(real_input.val()) === '' ? [] : real_input.val().split(',')).concat([text]).join(','));
};
var remove_tags = function(real_input, text) {
$('#' + tagfield_id_for(real_input) + " .tags .tag").each(function(i, v) {
v = $(v);
if (v.find('.text').html() === text) {
v.remove();
real_input = $(real_input);
var tags = $(real_input.val().split(',')).filter(function(i, v) {
return v !== text;
});
real_input.val(Array.prototype.join.call(tags));
}
});
};
var tagfield = function(real_input, elem) {
var tagfield = $('<div class="tagfield">').attr('id', tagfield_id_for(real_input)),
input = $('<input type="text"/>'),
buffer = $('<span class="buffer">'),
tags = $('<span class="tags">');
tagfield.append(tags);
tagfield.append(buffer);
tagfield.append(input);
tagfield.click(function(e) {
input.focus();
});
var check_add_tag = function() {
if (buffer.html()) {
var tag_text = buffer.html();
buffer.html('');
add_tags(real_input, tag_text);
}
};
var add_tag = function(text) {
};
input.keydown(function(e) {
if (e.which === KEYS.enter || e.which === KEYS.space || e.which === KEYS.comma) {
e.preventDefault();
check_add_tag();
}
if (e.which === KEYS.backspace) {
if (buffer.html() === "") {
remove_tags(real_input, tagfield.find('.tag').last().find('.text').html());
} else {
var s = buffer.html();
buffer.html(s.slice(0, s.length-1));
}
}
});
input.blur(check_add_tag);
input.keyup(function(e) {
buffer.append(input.val());
input.val('');
});
$(real_input).hide().after(tagfield);
};
})(jQuery);
沒有人可以告訴我,我怎麼能調用的方法add_tags()和remove_tags()?
感謝
