Using Javascript, how do I create an HTML table that can "accept" numeric matrix data from excel (or google spreadsheet), via "copy" in the spreadsheet and then "paste" into the table in the browser.
推荐答案
这只能在 IE 上可靠地工作，因为 Firefox(以及其他可能的)不允许在没有特别允许的情况下访问剪贴板；之前先粘贴到 textarea 的建议可能比这更好.
This would only work reliably on IE since Firefox (and likely others) don't allow access to the clipboard without specifically allowing it; the earlier suggestion of pasting into a textarea first might work better than this.
当您从电子表格复制时，通常单元格用制表符 (chr9) 分隔，行用 CR (chr13) 分隔.此脚本将剪贴板转换为二维数组，然后从中构建表格.不太优雅，但似乎可以从 Excel 中复制数据.
When you copy from a spreadsheet, generally the cells are separated with a tab (chr9) and the rows with a CR (chr13). This script converts the clipboard into a 2D array and then builds a table from it. Not too elegant but it seems to work copying data out of Excel.
<html>
<head>
<script language="javascript">
function clip() {
// get the clipboard text
var clipText = window.clipboardData.getData('Text');
// split into rows
clipRows = clipText.split(String.fromCharCode(13));
// split rows into columns
for (i=0; i<clipRows.length; i++) {
clipRows[i] = clipRows[i].split(String.fromCharCode(9));
}
// write out in a table
newTable = document.createElement("table")
newTable.border = 1;
for (i=0; i<clipRows.length - 1; i++) {
newRow = newTable.insertRow();
for (j=0; j<clipRows[i].length; j++) {
newCell = newRow.insertCell();
if (clipRows[i][j].length == 0) {
newCell.innerText = ' ';
}
else {
newCell.innerText = clipRows[i][j];
}
}
}
document.body.appendChild(newTable);
}
</script>
</head>
<body>
<input type="button" onclick="clip()">
</body>
</html>
