基于jquery的表头固定的若干方法

Posted in Javascript onJanuary 27, 2011

A:使用JQuery UI插件，用DIV替换table，overflow-y:hidden达到滚动，让 thead绝对定位达到固定的目的，方法如下： 

(function($){ 
$.chromatable = { 
defaults: { 
width: "900px", 
height: "300px", 
scrolling: "yes" 
} 
}; 
$.fn.chromatable = function(options){ 
var options = $.extend({}, $.chromatable.defaults, options); 
return this.each(function(){ 
var $this = $(this); 
var $uniqueID = $(this).attr("ID") + ("wrapper"); 
$(this).css('width', options.width).addClass("_scrolling"); 
$(this).wrap('<div class="scrolling_outer"><div id="'+$uniqueID+'" class="scrolling_inner"></div></div>'); 
$(".scrolling_outer").css({'position':'relative'}); 
$("#"+$uniqueID).css( 
{'border':'1px solid #CCCCCC', 
'overflow-x':'hidden', 
'overflow-y':'auto', 
'padding-right':'17px' 
}); 
$("#"+$uniqueID).css('height', options.height); 
$("#"+$uniqueID).css('width', options.width); 
$(this).before($(this).clone().attr("id", "").addClass("_thead").css( 
{'width' : 'auto', 
'display' : 'block', 
'position':'absolute', 
'border':'none', 
'border-bottom':'1px solid #CCC', 
'top':'1px' 
})); 
$('._thead').children('tbody').remove(); 
$(this).each(function( $this ){ 
if (options.width == "100%" || options.width == "auto") { 
$("#"+$uniqueID).css({'padding-right':'0px'}); 
} 
if (options.scrolling == "no") { 
$("#"+$uniqueID).before('<a href="#" class="expander" style="width:100%;">Expand table</a>'); 
$("#"+$uniqueID).css({'padding-right':'0px'}); 
$(".expander").each( 
function(int){ 
$(this).attr("ID", int); 
$( this ).bind ("click",function(){ 
$("#"+$uniqueID).css({'height':'auto'}); 
$("#"+$uniqueID+" ._thead").remove(); 
$(this).remove(); 
}); 
}); 
$("#"+$uniqueID).resizable({ handles: 's' }).css("overflow-y", "hidden"); 
} 
}); 
$curr = $this.prev(); 
$("thead:eq(0)>tr th",this).each( function (i) { 
$("thead:eq(0)>tr th:eq("+i+")", $curr).width( $(this).width()); 
}); 
if (options.width == "100%" || "auto"){ 
$(window).resize(function(){ 
resizer($this); 
}); 
} 
}); 
}; 
function resizer($this) { 
$curr = $this.prev(); 
$("thead:eq(0)>tr th", $this).each( function (i) { 
$("thead:eq(0)>tr th:eq("+i+")", $curr).width( $(this).width()); 
}); 
}; 
})(jQuery);

页面调用如下： 
... 
<script type="text/javascript" src="jquery-ui-min.js"></script> 
<script> 
$(function(){ 
$("#yourTableID").chromatable({ 
width: "900px", 
height: "400px", 
scrolling: "yes" 
}); 
}); 
</script> 
... 
<table id="yourTableID" width="100%" border="0" cellspacing="0" cellpadding="0"> 
<thead> 
<tr> 
<th>Check out this header</th> 
<th>Look here's another one</th> 
<th>Wow, look at me!</th> 
</tr> 
</thead> 
<tbody> 
<tr> 
<td>Some content goes in here</td> 
<td>Praesent vitae ligula nec orci pretium vestibulum</td> 
<td>Maecenas tempus dictum libero</td> 
</tr> 
... 
<tr> 
<td>Quisque in wisi quis orci tincidunt fermentum</td> 
<td>Mauris aliquet mattis metus</td> 
<td>Etiam eu ante non leo egestas nonummy</td> 
</tr> 
</tbody> 
</table>

此方法IE和FF的兼容性都很好，推荐。
B：利用css滤镜实现，但FF不支持微软的东西，不兼容。DOM如下：

/*重点：固定表头样式*/

C:最简单的方法当然是写2个table，用DIV的overflow-y:auto来实现，兼容性绝对没问题，麻烦之处在于2个table的对齐问题，另外用脚本赋予高度的话，需要加onresize()方法。DOM如下：
