在表单输入焦点上，显示div。在多个输入和隐藏的div上模糊隐藏div

Question

我有2个文本输入字段，每个文本输入字段都有一个关联的隐藏div。 当客户专注于每个文本字段时，将显示隐藏的div。如果客户在文本字段或关联的div以外的任何位置单击/聚焦，则它们都将消失（一次只能看到1个隐藏的div）。

我找到了working example snippet for a single text field input，但是我不知道如何为两个单独的输入/ div调整脚本。

1）“搜索市场”中的焦点显示“选择市场” div（暗区单击将关闭/隐藏div）。

2）“搜索符号”中的焦点显示“选择符号” div（深色区域单击将关闭/隐藏div）。

您需要在交易品种和市场（.select-filters之间划分类别。 请注意，我将select-filters market 用于市场，并将select-filters symbol 用于符号。

要分离焦点，您需要使用诸如div.select-filters.market的指定函数和div.select-filters.symbol的符号的指定函数：

$('#search-markets').focus(function() {
    $('div.select-filters.market').css('display', 'flex');
    $(document).bind('focusin.select-filters.market click.select-filters.market',function(e) {
        if ($(e.target).closest('.select-filters.market, #search-markets').length) return;
        $(document).unbind('.select-filters.market');
        $('div.select-filters.market').slideUp(300);
    });
});

$('#search-symbols').focus(function() {
    $('div.select-filters.symbol').css('display', 'flex');
    $(document).bind('focusin.select-filters.symbol click.select-filters.symbol',function(e) {
        if ($(e.target).closest('.select-filters.symbol, #search-symbols').length) return;
        $(document).unbind('.select-filters.symbol');
        $('div.select-filters.symbol').slideUp(300);
    });
});
$('div.select-filters').hide();
