3Z版基于jquery的图片复选框(asp.net+jquery)

先上效果图:

html:

<asp:CheckBoxList ID="CheckBoxList1" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow" Width="280px"> 
<asp:ListItem>01</asp:ListItem> 
<asp:ListItem>02</asp:ListItem> 
<asp:ListItem>03</asp:ListItem> 
<asp:ListItem>04</asp:ListItem> 
<asp:ListItem>05</asp:ListItem> 
<asp:ListItem>06</asp:ListItem> 
<asp:ListItem>07</asp:ListItem> 
<asp:ListItem>08</asp:ListItem> 
<asp:ListItem>09</asp:ListItem> 
<asp:ListItem>10</asp:ListItem> 
<asp:ListItem>11</asp:ListItem> 
<asp:ListItem>12</asp:ListItem> 
<asp:ListItem>13</asp:ListItem> 
<asp:ListItem>14</asp:ListItem> 
<asp:ListItem>15</asp:ListItem> 
<asp:ListItem>16</asp:ListItem> 
<asp:ListItem>17</asp:ListItem> 
<asp:ListItem>18</asp:ListItem> 
<asp:ListItem>19</asp:ListItem> 
<asp:ListItem>20</asp:ListItem> 
<asp:ListItem>21</asp:ListItem> 
<asp:ListItem>22</asp:ListItem> 
<asp:ListItem>23</asp:ListItem> 
<asp:ListItem>24</asp:ListItem> 
<asp:ListItem>25</asp:ListItem> 
<asp:ListItem>26</asp:ListItem> 
<asp:ListItem>27</asp:ListItem> 
<asp:ListItem>28</asp:ListItem> 
<asp:ListItem>29</asp:ListItem> 
<asp:ListItem>30</asp:ListItem> 
<asp:ListItem>31</asp:ListItem> 
<asp:ListItem>32</asp:ListItem> 
<asp:ListItem>33</asp:ListItem> 
</asp:CheckBoxList>

JS:

(function($){ 
$.fn.imagecheckbox = function(options) { 
var defaults = { 
checked: "images/radio.gif", 
unchecked: "no_images/radio.gif", 
css: "on", 
hide_radios_checkboxes: false 
}; 
var opt = $.extend(defaults, options); 
this.each(function(){ 
var obj = $(this); 
var type = obj.attr('type'); 
var id = obj.attr('id'); 
if(!opt.hide_radios_checkboxes){ 
obj.css('display','none'); 
} 
if(obj.attr('checked')){ 
$("label[for='" + id + "']").attr('class',opt.css); 
}else{ 
$("label[for='" + id + "']").attr('class','out'); 
} 
$("label[for='" + id + "']").click(function(){ 
$("#" + id).trigger("click"); 
if($(this).attr('class') == opt.css){ 
$(this).attr('class', 'out'); 
}else { 
$(this).attr('class', opt.css); 
} 
}); 
}); 
} 
})(jQuery);

使用方式:(把css一起发出来)

<script type="text/javascript" src="/scripts/imagetick.js"></script> 
<script type="text/javascript"> 
$(function(){ 
$("input[type='checkbox']").imagecheckbox({ // the selector can be a class as well 
checked: "/images/red.gif", 
onchecked: "/images/no_check.gif", 
css: "on" 
}); 
}); 
</script> 
<style type="text/css"> 
input{} 
label{display:inline-block;width:25px;height:22px;padding-top:3px;text-align:center;font:800 12px/150% arial;position:relative;left;-210px;} 
.on{background:url(/images/red.gif) no-repeat;} 
.out{background:url(/images/no_check.gif) no-repeat;} 
</style>
