jquery - 取消选中属性为 "checked"的表中的复选框

Question

我正在创建一个带有复选框的表，我想将状态(选中/取消选中)作为复选框输入 html 类中的一个属性。到目前为止，我只能检查它，但我不能取消选中它，因为行

$(this).find(".checkbox-input").prop("checked", "checked");

似乎没有为我的复选框输入设置任何内容。

我做错了什么吗？我是新手，因为我不是前端工程师。任何帮助表示赞赏!

$(".checkbox-action").click(function() {

    if ($(this).prop("tagName").toLowerCase() == "td") {
      $(this).parent().addClass("selected-bg");

试试这个。你错了更多的东西。自己检查一下
