在我的previous post上,我问了如何使用箭头键导航表格单元格。现在我正在尝试创建另一个与第一个表相同的表。使用箭头键导航两个带有输入文本的HTML表格
如何实现这一目标?
这是我到目前为止。
var active = 0;
//$('#navigate td').each(function(idx){$(this).html(idx);});
rePosition();
$(document).keydown(function(e) {
var inp = String.fromCharCode(event.keyCode);
if (!(/[a-zA-Z0-9-_ ]/.test(inp) || event.keyCode == 96)){
reCalculate(e);
rePosition();
// if key is an arrow key, don't type the user input.
// if it is any other key (a, b, c, etc)
// edit the text
if (e.keyCode > 36 && e.keyCode < 41) {
return false;
}
}
});
$('td').click(function() {
active = $(this).closest('table tbody').find('td').index(this);
rePosition();
});
function reCalculate(e) {
var rows = $('#navigate tbody tr').length;
var columns = $('#navigate tbody tr:eq(0) td').length;
var temp;
if (e.keyCode == 37) { //move left or wrap
temp = active;
while (temp > 0) {
temp = temp - 1;
// only advance if there is an input field in the td
if ($('#navigate tbody tr td').eq(temp).find('input').length != 0) {
active = temp;
break;
}
}
}
if (e.keyCode == 38) { // move up
temp = active;
while (temp - columns >= 0) {
temp = temp - columns;
// only advance if there is an input field in the td
if ($('#navigate tbody tr td').eq(temp).find('input').length != 0) {
active = temp;
break;
}
}
}
if (e.keyCode == 39) { // move right or wrap
temp = active;
while (temp < (columns * rows) - 1) {
temp = temp + 1;
// only advance if there is an input field in the td
if ($('#navigate tbody tr td').eq(temp).find('input').length != 0) {
active = temp;
break;
}
}
}
if (e.keyCode == 40) { // move down
temp = active;
while (temp + columns <= (rows * columns) - 1) {
temp = temp + columns;
// only advance if there is an input field in the td
if ($('#navigate tbody tr td').eq(temp).find('input').length != 0) {
active = temp;
break;
}
}
}
}
function rePosition() {
console.log(active);
$('.active').removeClass('active');
$('#navigate tbody tr td').eq(active).addClass('active');
$('#navigate tbody tr td').find('input').removeClass('textClass');
$('#navigate tbody tr td').eq(active).find('input').addClass('textClass');
$('#navigate tbody tr td').eq(active).find('input').select();
var input = $('#navigate tbody tr td').eq(active).find('input').focus();
scrollInView();
}
function scrollInView() {
var target = $('#navigate tbody tr td:eq(' + active + ')');
if (target.length) {
var top = target.offset().top;
$('html,body').stop().animate({
scrollTop: top - 100
}, 400);
return false;
}
}
td.active{
border:2px solid #2c3e50;
font-weight:bold;
background-color:#ddd;
}
.textClass{
font-weight:bold;
}
input:focus {
outline: none;

当你到达第一个表的结尾时,你想要继续在第二个表中导航? – tejashsoni111
