我使用此代码获取TD的可编辑How to make HTML table "Excel-like" editable for multiple cells, i.e. simultaneous copy-paste features?
现在,我尝试添加新行,因为在最后一个td上输入了tab键。
FIDDLE
HTML:
<table width="100%" id="table" class="table" border="1" cellpadding="0" cellspacing="0">
<tr>
<td><div contenteditable>Some Text over here</div></td>
<td><div contenteditable>Some Text over here</div></td>
<td><div contenteditable>Some Text over here</div></td>
<td><div contenteditable>Some Text over here</div></td>
</tr>
<tr>
<td><div contenteditable>Some Text over here</div></td>
<td><div contenteditable>Some Text over here</div></td>
<td><div contenteditable>Some Text over here</div></td>
<td><div contenteditable>Some Text over here</div></td>
</tr>
</table>
字幕:
function init()
{
var tables = document.getElementsByClassName("table");
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>/);
}
init();
$('td:last-child div').keydown(function(e) {
console.log('keyup called');
var code = e.keyCode || e.which;
if (code == '9') {
// var table=document.getElementById("table");
//table.insertRow(0);
alert('Pressed');
return false;
}
});
Tab键起作用的原因是,在您最后一个孩子之后,您在选择时会发出警报。但是我不知道为什么insertRow不起作用。从这里得到它http://www.w3schools.com/jsref/met_table_insertrow.asp
任何帮助或建议,将不胜感激!
最佳答案
将焦点事件与回调一起使用
$(document).ready(function(){
$(document).on("focus",'#table tr:last-child td:last-child',function() {
//append the new row here.
var table = $("#table");
table.append('<tr>\
<td><div contenteditable>Some Text over here</div></td>\
<td><div contenteditable>Some Text over here</div></td>\
<td><div contenteditable>Some Text over here</div></td>\
<td><div contenteditable>Some Text over here</div></td>\
</tr>');
});
});
\用于执行多行javascript字符串。
除了做长字符串,您还可以这样做:
var row = jQuery('<tr></tr>');
var numCols = 4;
for(var i=0; i<numCols; i++) {
var col = jQuery('<td></td>');
var div = jQuery('<div contenteditable></div>');
col.append(div);
row.append(col);
}
