javascript - 为每个 child 循环 jQuery

Question

我如何编写使用 for(i=1; ... ...); 的短代码？允许我遍历每个 child 并添加不同类的函数。

$('#WebPartWPQ3 > table:first-child').addClass('blogpost1');
$('#WebPartWPQ3 > table:nth-child(2)').addClass('blogpost2');
$('#WebPartWPQ3 > table:nth-child(3)').addClass('blogpost3');
$('#WebPartWPQ3 > table:nth-child(4)').addClass('blogpost4');
$('#WebPartWPQ3 > table:nth-child(5)').addClass('blogpost5');
$('#WebPartWPQ3 > table:nth-child(6)').addClass('blogpost6');
$('#WebPartWPQ3 > table:nth-child(7)').addClass('blogpost7');
$('#WebPartWPQ3 > table:nth-child(8)').addClass('blogpost8');
$('#WebPartWPQ3 > table:nth-child(9)').addClass('blogpost9');

Answer 1

尝试

$('#WebPartWPQ3 > table').each(function(i,j){

 $(this).addClass("blogpost"+(i+1));
});
