滚动时修复HTML表头

时间:2013-03-28 15:50:37

标签: javascript jquery html css

我有一个退出很长的HTML表格,我需要修改滚动标题,我发现了很多很多插件和技巧,但没有一个适用于我。

我猜想没有对我有用的原因是:

  1. 所有解决方案都从表格中分离标题
  2. 他们使用每列的固定宽度来保持标题位于内容之上
  3. 我的表格非常敏感,并且可以伸展以获得全宽度(width=100%
  4. 有人有建议吗?

    编辑:感谢ashley我更新了我的css技术

我认为我想出了一个相当不错的问题解决方案,它比我想要的要深一点,但我对结果非常满意。

enter image description here

它的工作方式是文档就绪,克隆表头,将克隆的大小设置为表头的大小,并将其放在另一个头的顶部。滚动时如果窗口顶部低于表格顶部,我们将克隆的top设置在窗口的顶部。在调整大小时,我们会重新计算<th>尺寸。

请注意,我将<th>放入与{。

分开的<thead>

jsFiddle

var tableBaseTop;
var originalHeader;
var floatingHeader;

$(document).ready(function () {
    tableBaseTop = $('table th').offset().top;
    originalHeader = $('thead');
    floatingHeader = originalHeader.clone();
    floatingHeader
        .css('position', 'absolute')
        .css('top', 0);

    setFloatingHeaderSize();

    $('table').prepend(floatingHeader);

    $(window).scroll(function () {
        var windowTop = $(window).scrollTop();

        if (windowTop > tableBaseTop)
            floatingHeader.css('top', windowTop - tableBaseTop);
        else
            floatingHeader.css('top', 0);
    });

    $(window).resize(setFloatingHeaderSize);
});

function setFloatingHeaderSize() {
    var originalThs = originalHeader.find('th');
    var floatingThs = floatingHeader.find('th');
    for (var i = 0; i < originalThs.length; i++) {
        floatingThs.eq(i)
            .css('width', originalThs.eq(i).width())
            .css('height', originalThs.eq(i).height());
    }
}

Firefox标题宽度问题

我设法解决了这个问题,但我无法弄清楚如何使用jQuery的助手来解决这个问题。问题是,当实际的宽度/高度是小数时,jQuery给了我整数大小,我需要它们作为浮点数。这是我用工作小提琴改变的代码部分。

jsFiddle

function setFloatingHeaderSize() {
    var originalThs = originalHeader.find('th');
    var floatingThs = floatingHeader.find('th');
    for (var i = 0; i < originalThs.length; i++) {
        var padding = 
            parseFloat(window.getComputedStyle(this.originalThs[i], null).getPropertyValue('padding-left').replace('px', ''), 10) +
            parseFloat(window.getComputedStyle(this.originalThs[i], null).getPropertyValue('padding-right').replace('px', ''), 10);

        floatingThs.eq(i)
            .css('width', this.originalThs[i].offsetWidth - padding)
            .css('height', this.originalThs[i].offsetHeight - padding);
    }
}

我用this修改了你的小提琴,它将标题修复到网格的顶部。但它确实有将瓷砖固定在左上方的缺点。

希望这有助于您获得完整答案。

table {
    width: 100%;
    border-collapse: collapse;
    position: relative;
}
div.scoll {
    overflow: scroll;
    height: 300px;
}
.center {
    text-align: center;
}
thead {
    position: static;
    width: 100%;
}
thead tr {
    position: fixed;
}

并将html改为看起来像

<div class="scoll">
<table>
        <thead>
            <tr>
                <th>Code</th>

                <th>Message Text</th>
                <th>Progress</th>
                <th>Current</th>
                <th>X</th>
                <th>Y</th>
                <th>Z</th>
                <th>W</th>
                <th>Result</th>

将标题行分隔到另一个表并添加一些jquery代码:

HTML:

<table class="headtable">
<tr>
    <td>name</td>
    <td>value</td>
    <td>action</td>
</tr>
</table>
<div class="scrolltable">
    <table class="valuetable">
        <tr>
            <td>hay 1</td>
            <td>1</td>
            <td>edit</td>
        </tr>
<tr>
            <td>hay 1</td>
            <td>1</td>
            <td>edit</td>
        </tr>
        <tr>
            <td>hay 1</td>
            <td>1</td>
            <td>edit</td>
        </tr>
        <tr>
            <td>hay 1</td>
            <td>1</td>
            <td>edit</td>
        </tr>
        </table>
</div>

js code:

$('.headtable tr').children().each(function(index)
    {      
      $(this).width($('.valuetable tr:first td').eq(index).width());
    });
如果需要,

样式:

.scrolltable{height:500px; overflow:auto;}

如果你想自动调整大小(响应):

$(window).resize(function(){
$('.headtable tr').children().each(function(index)
        {      
          $(this).width($('.valuetable tr:first td').eq(index).width());
        });
});

如果fixed- height 列标题可以接受,则可以使用纯CSS解决此问题。

这是一个配置了流量表宽度和自动列宽的示例,就像OP的表格一样: jsFiddle

请注意,只有在该示例中必要时才会显示垂直滚动条,因此您可能需要调整框架的大小才能看到它。

下面的代码与小提琴相同,但具有固定的桌面高度。只要有足够的行超出指定的高度,滚动条就会始终显示在该配置中:

必须更改背景颜色并删除边框,使其看起来像完全,就像OP的表格一样。有关进行这些类型更改的说明,请参阅CSS注释。
