我正在尝试创建类似网格的结构。我想在循环中创建一个循环,并根据它是列还是行来附加div。以下是我的 attempt :
for (var row = 0; row < 8; row++) {
$('#board').append('<div class="row">'+ row +'</div>');
}
我想用简单的Javascript复制(代码很可能不正确,我只是想展示一个我想要的例子):
var board = document.getElementById('board');
for (var row = 0; row < 8; row++) {
board.write('<div class="row">');
for(var col = 0; col < 8; col++) {
var row = document.getElementsByClassName('row');
row.write('<div class="piece">'+col+'</div>')
}
board.write('</div>');
}
如果我能以某种方式复制document.write()
中的jQuery
方法,那将会非常有用。当我试图包含一个forloop时,.append()
对我不起作用。

你只需要循环遍历行然后单元格来构建一个单独的html字符串,而不是只附加一次:
var rows = [], cells = [];
for (var row = 0; row < 8; row++) {
cells = [];
for (var cell = 0; cell < 8; cell++) {
cells.push('<div class="piece">'+ row +'</div>');
}
rows.push('<div class="row">' + cells.join('') + '</div>');
}
$('#board').html(rows.join(''));

尝试以下操作 - 如果您需要更具体地操作DOM,请使用JQuery
var board = document.getElementById('board'),
html = '';
for (var row = 0; row < 8; row++) {
html += '<div class="row">';
for(var col = 0; col < 8; col++) {
html += '<div class="piece">'+col+'</div>';
}
html += '</div>';
}
board.innerHTML = html;
或者使用JQuery:
var board = $('#board');
...
board.append($(html));

据我所知,您希望最终得到这样的结构:
<div id="board">
<div class="row">
<div class="piece"></div>
<div class="piece"></div>
<div class="piece"></div>
(...)
</div>
(...)
</div>
我们假设您已经有一个董事会(<div id="board"></div>
)。
for( var row = 0; row < 8; row++ ) {
//Create a row
$row = $('<div class="row"></div>');
//Stuff 8 pieces in that row
for( var col = 0; col < 8; col++ ) {
$row.append( $('<div class="piece">' + col + '</div>') );
}
//Add the row to the board
$('#board').append( $row );
}
编辑:在您的情况下,您甚至可以将其简化为:
//Stuff 8 rows in the board
for( var row = 0; row < 8; row++ ) {
$('#board').append( $('<div class="row"></div>') );
}
//Stuff 8 pieces in every of the 8 rows
//This can be done because the piece is the same for every row
for( var col = 0; col < 8; col++ ) {
$('.row').append( $('<div class="piece">' + col + '</div>') );
}
