使用querySelectorAll获取选择的选项 [英] Getting selected options with querySelectorAll

问题描述

我想知道在Javascript中是否有可能使用Selctors API在<select multiple>字段中获取当前选择的选项，而不是对所有选项进行愚蠢"的迭代.

I wonder if it's possible in Javascript to get the currently selected options in a <select multiple> field using the Selctors API rather than a "stupid" iteration over all options.

select.querySelectorAll('option[selected="selected"]')仅返回原始HTML中标记为预选的选项，这不是我想要的.有什么想法吗?

select.querySelectorAll('option[selected="selected"]') only returns the options that were marked as preselected in the original HTML, which is not what I'm looking for. Any ideas?

推荐答案

document.querySelectorAll('option:checked')

即使在IE9上也可以使用；)

Works even on IE9 ;)
