FireFox 4不再支持可滚动的TBody - 变通方法?

[英]FireFox 4 no longer supports scrollable TBody - workarounds?

正如Firefox 4更新日志中所提到的,将不再支持可滚动的<tbody>

有一堆变通办法 --javascript或2个单独的表 - 但它们都没有解决所有问题。 Javascript显然较慢(600行你可以忘记尝试滚动表格),2个表格的单元格宽度会有问题。

你知道是否有一些很酷的方法来做到这一点? 我们正在使用jsf / facelets,现在必须重做标签,从一个好主意开始会很棒:-)

我知道你试图避免使用js /单独的表实现,但它是我能找到的唯一可以在多个浏览器中使用的表。 试试http://www.tablefixedheader.com/ 它是一个jquery解决方案,在我的有限测试中,在IE6 / IE8 / FF3上工作。 (尚未测试过FF4)。

感谢MozillaZine的digitaldigs,我能够通过一些修改使其工作。 该修复程序适用于FF4,FF7和FF11。

我希望这有帮助! :)

我修复过的问题 - 1. scrollWidth对我不起作用,所以不得不去找offsetWidth

  1. 滚动条宽度16像素也没有帮助,所以删除它。 取而代之的是我的t style风格 -

    .scrollContent {overflow-x:hidden; 溢出-Y:滚动; / *我只为Mozilla做过这个。 IE将显示2个滚动条,如果应用* / display:block; }

  2. 随着#2的变化,我不得不填充标题的最后一个单元格来容纳滚动条。

    / *我只为Mozilla做过这个。 不适用于IE * /

    .fixedHeader tr th:last-child {padding-right:20px; }

  3. 我的固定头表有colspan使用了很多,因此无法设置宽度,所以我首先寻找一个正确的行与正确的单元格数,然后我处理。

我的代码如下所示:

function makeMeFixedHeader(){ 
    var tbodys = document.getElementsByName("scrollTableBody");
    if (tbodys){
        for(var i=0;i<tbodys.length;i++){
            // We can put logic here to check if the current height 
            // of tbody has crossed the specified limit or not 
            do_tbodyscroll(tbodys[i]);
        }
    }
}


function do_tbodyscroll(_tbody){
    // get the table node 
    var table = _tbody.parentNode;

    // Get the Last row in Thead ... 
    // COLGROUPS USING COLSPAN NOT YET SUPPORTED
    var thead = table.getElementsByTagName("THEAD")[0];
    var _rows = thead.getElementsByTagName("TR");
    var tableheader = _rows[_rows.length - 1];
    var headercells = tableheader.cells;

    // rows of tbody 
    var _frows = _tbody.getElementsByTagName("TR");

    // first row of tbody 
    var _fr = _tbody.getElementsByTagName("TR")[0];
    //var _fr = _tbody.getElementsByName("scrollTableRow")[0];

    // first row cells .. 
    var _frcells = _fr.cells;

    if (_frcells.length < headercells.length){
        var rowCount = 1;
        while (rowCount < _frows.length){
            // nth  row of tbody 
            _fr = _tbody.getElementsByTagName("TR")[rowCount];
            //var _fr = _tbody.getElementsByName("scrollTableRow")[rowCount];

            // nth row cells .. 
            _frcells = _fr.cells;

            if (headercells.length == _frcells.length){
                break;
            }
            rowCount++;
        }
    }

    // Apply width to header ..
    for(var i=0; i<headercells.length; i++){    
        if (tableheader.cells[i].offsetWidth != _fr.cells[i].offsetWidth){
            var lastColumn = (i == headercells.length-1)?true:false;
            var changeWidth = (lastColumn)? ((rowCount >= 1)?true:false)
                    :true;
            var headerW = tableheader.cells[i].offsetWidth;
            var cellW = _fr.cells[i].offsetWidth;

            if (headerW < cellW){
                tableheader.cells[i].width = cellW;
                _fr.cells[i].width = tableheader.cells[i].width;

                if (lastColumn)
                    tableheader.cells[i].width = tableheader.cells[i].offsetWidth-20; 

            }else{
                tableheader.cells[i].width = headerW;
                _fr.cells[i].width = tableheader.cells[i].width;

                if (lastColumn)
                    _fr.cells[i].width = tableheader.cells[i].offsetWidth-20;
            }
        }
    }

    //var j = headercells.length-1;
    // ADD 16 Pixel of scroll bar to last column ..
    //tableheader.cells[j].width =  _fr.cells[j].offsetWidth + 20;

    tableheader.style.display = "block";
    _tbody.style.display = "block"; 
}

PrimeFacesRichFaces具有可滚动的数据表组件,它们通过ajax获取新行。

(无论如何,两个JSF组件库都使用jQuery)

尝试这个页面的第一个方法,带有单个表的纯CSS(表格周围有两个div,并且thead是绝对定位的): tablescroll除了IE7 / FF3.6之外,似乎可以在FF4 / IE9 / IE8上工作。

我升级后刚刚被这个猛烈抨击。 嘘。

我在管子里发现了这个。

此代码在FFX 4中工作。不在IE8中......可以修改。

为什么不使用可滚动的div? 也许这两个选项之一:

<table>
 <row>
  <cell>
   <div of headers>
   <div of content (scrollable)>
  </cell>
 </row>
</table>

或者更简单:

<div of headers>
<div (scrollable)>
 <table of content, no headers>
</div>

我不知道但是嘿,我不是Michaelangelo :)

我参与了一个我想与你分享的无框架原型。 它适用于Firefox 4 +,IE7-8(尚未检查6或9)Safari和Chrome。

最大的未解决的问题是当静态标头在数据列之前耗尽空间时要做什么。

对于我正在努力的实际项目坦率地说,我退出了滚动的tbody并且进行了分页。 但我正在处理25列以上的排序和可能的1000行。

无论如何,这是我放弃它之前所到达的地方。 如果你改进它,请发布你的补充:希望这有帮助。
