在显示下拉菜单时单击提交不会在 chrome 中提交表单，但在 IE 中会提交

Question

我有一个简单的日期范围搜索表单，其中包含使用引导程序的“高级选项”下拉菜单。我的问题是，当用户在显示高级下拉列表时按下提交按钮时，它在不同浏览器中具有不同的行为。 在 IE 中，下拉菜单关闭，表单将被提交。在 Chrome 中，下拉菜单关闭，但我必须再次单击提交按钮才能提交表单。

如果我拦截按钮单击事件并手动提交，那么我可以在 Chrome 中单击一次，但随后表单在 IE 中提交两次。

有什么方法可以在两个浏览器中获得一致的行为？

$('#date-range-box').daterangepicker({

  "startDate": "07/14/2017",
  "endDate": "07/20/2017"
});


$('.dropdown-menu').click(function(e) {
  e.stopPropagation(); //This will prevent the event from bubbling up and close the dropdown when you type/click on text boxes.
});

$('#search-form').submit(function(ev) {
  ev.preventDefault();
  showMsg('submitted');
});

function showMsg(msg) {
  var options = {

    hour: "2-digit",

  var dateS = new Date().toLocaleString('en-GB', options);
  toastr.options.positionClass = "toast-bottom-right";
  toastr.info(msg + ' - ' + dateS, {

尝试使用return false 选项而不是ev.preventDefault()
