我使用以下代码,并希望每次为突出显示的单元格创建一个边框
HTML 代码:
<table id="table-1">
<thead>
<tr>
<th></th>
<th>Col1</th>
<th>Col2</th>
<th>Col3</th>
<th>Col4</th>
<th>Col5</th>
<th>Col6</th>
<th>Col7</th>
<th>Col8</th>
<th>Col9</th>
<th>Col10</th>
</tr>
</thead>
<tbody>
<tr>
<th>Row1</th>
<td>info</td>
<td>info</td>
<td>info</td>
<td>info</td>
<td>info</td>

CSS:
.hi_td {background-color:red}
.hi_th {background-color:#fcc}
Javascript:
mdown = false;
msel = [[], []];
var funcfalse = function () {
console.log('selsta');
}
var getpos = function (o, i) {
var o = $(o); // get position of current cell
msel[0][i] = o.parent().index(); // set row
msel[1][i] = o.index(); // set column
return msel;
}
var modsel = function (o) {
var numsrt = function (a, b) {
return a - b;
}
var r = getpos(o, 1)[0].slice(0);
r.sort(numsrt);
var c = msel[1].slice(0);
c.sort(numsrt);
$trs = $('#table-1 tbody tr');
$('td', $trs).removeClass('hi_td');
$trs.slice(r[0], r[1] + 1).each(function () {
$('td', this).slice(c[0] - 1, c[1]).addClass('hi_td');
});
$("#table-1 thead tr th").removeClass('hi_th')
.slice(c[0], c[1] + 1).addClass('hi_th');
$("#table-1 tbody tr th").removeClass('hi_th')
.slice(r[0], r[1] + 1).addClass('hi_th');
}
var hover = function (ev) {
if (mdown) modsel(this);
}
var mo = function (ev) {
mdown = (ev.type == 'mousedown') ? 1 : 0;
getpos(this, 1 - mdown);
if (mdown) modsel(this);
}
var $tbl = $("#table-1"),
$tblHead = $("#table-1 thead tr");
$("tbody td", $tbl)
.on({
"mousedown": mo,
"mouseup": mo,
"mouseenter": hover,
"selectstart": funcfalse
});
