.closest和.find在jQuery中

Posted 2021-02-24

.closest and .find are very useful - surprised I haven't heard of them before.

// Expand Tables
	$(".expandTable").toggle(
		function(){
			$(this).closest('.tableSection').find('.tradeTable').fadeIn();
			$(this).closest('.tableSection').find('.arrow').html('↓');
		},
		function(){
			$(this).closest('.tableSection').find('.tradeTable').fadeOut();
			$(this).closest('.tableSection').find('.arrow').html('→');
		}
	);
