javascript - 如何在javascript中以模态隐藏表单

Question

我有一个包含两种形式的模式，我想在选中其中一个单选按钮时在它们之间切换，所以我需要在模式加载中隐藏其中一个，我做了以下代码，但它没有隐藏, 任何人都可以帮助我吗？需要在模态加载时隐藏的表单调用 LocateOnMap 以隐藏其所有内容。

<div class="modal fade" id="modal-Frm">

Answer 1

你不能有 <form></form>在 <form></form> 下, 所以删除了而不是使用 div .默认分配 hidden类别为 LocateOnMap .然后在change radio的事件你可以使用 jquery toggleClass()切换 LocateOnMap 可见性的方法& EnterAddress .

$("#modal-Frm").modal("show");


$('input[name=optradio]').change(function() {
  $("#EnterAddress,#LocateOnMap").toggleClass("hidden");
});
