如何使HTML表格“类似Excel的”编辑多个细胞,即同时复制粘贴功能?(How to make H

2019-09-01 10:59发布

我需要我的HTML表格可编辑,以便用户插入的数据可以被发送到服务器。 然而,由于该表的尺寸(50行),它不会是方便用户一个接一个插入的数据点,如果我介绍contenteditable属性如下:

<table>
<tr><td><div contenteditable>editable</div></td><td><div contenteditable>editable</div></td></tr>
//...........
</table>

我怎样才能让我的表是可编辑的类似excel表格,如果可能的话,而无需使用道场等? 我一直在使用ExcelAdapter类在Java中做到了这一点。 有没有什么办法,我能做到这一点的HTML?

Answer 1:

您可以将监听器添加到input每个单元格的事件,如果单元格中包含多个数据项在接下来的细胞分裂他们。

function init()
{
    var tables = document.getElementsByClassName("editabletable");
    var i;
    for (i = 0; i < tables.length; i++)
    {
        makeTableEditable(tables[i]);
    }
}

function makeTableEditable(table)
{
    var rows = table.rows;
    var r;
    for (r = 0; r < rows.length; r++)
    {
        var cols = rows[r].cells;
        var c;
        for (c = 0; c < cols.length; c++)
        {
            var cell = cols[c];
            var listener = makeEditListener(table, r, c);
            cell.addEventListener("input", listener, false);
        }
    }
}

function makeEditListener(table, row, col)
{
    return function(event)
    {
        var cell = getCellElement(table, row, col);
        var text = cell.innerHTML.replace(/<br>$/, '');
        var items = split(text);

        if (items.length === 1)
        {
            // Text is a single element, so do nothing.
            // Without this each keypress resets the focus.
            return;
        }

        var i;
        var r = row;
        var c = col;
        for (i = 0; i < items.length && r < table.rows.length; i++)
        {
            cell = getCellElement(table, r, c);
            cell.innerHTML = items[i]; // doesn't escape HTML

            c++;
            if (c === table.rows[r].cells.length)
            {
                r++;
                c = 0;
            }
        }
        cell.focus();
    };
}

function getCellElement(table, row, col)
{
    // assume each cell contains a div with the text
    return table.rows[row].cells[col].firstChild;
}

function split(str)
{
    // use comma and whitespace as delimiters
    return str.split(/,|\s|<br>/);
}

window.onload = init;

Answer 2:

您可以通过添加轻松实现这个handsontable

更改任何股利一个excel表格

var $container = $("#divid");
$container.handsontable({
data: getData(),
rowHeaders: true,
colHeaders: true,
contextMenu: true  //forces dom to use custom right click functionality like add row delete row add column etc 
});
