Question

我有一个登录弹出窗口，里面有一个表单。问题是表单在提交时无效。为什么是这样？我尝试过移动表单元素，但没有任何工作。我误解了输入的某些部分吗？操作有意为hi，因此我会转到完全不同的页面。但没有任何反应......

这就是我的代码现在的样子：

<script>
    $.fn.expose = function(options) {

  var $modal = $(this),
    $trigger = $('a[href="' + this.selector + '"]');

  $modal.on("expose:open", function() {

    $modal.addClass("is-visible");
    $modal.trigger("expose:opened");
  });

  $modal.on("expose:close", function() {

    $modal.removeClass("is-visible");
    $modal.trigger("expose:closed");
  });

  $modal.on("click", function(e) {
    if ($(e.target).is($modal) || $(e.target).is('.close')) {
      e.preventDefault();
      $modal.trigger("expose:close");
    }
  });

  $modal.add($modal.find(".close")).on("click", function(e) {

    e.preventDefault();

    // if it isn't the background or close button, bail
    if (e.target !== this)
      return;

    $modal.trigger("expose:close");
  });

  return;
}

$("#Popup").expose();

// Example Cancel Button

$(".cancel").on("click", function(e) {

  e.preventDefault();
  $(this).trigger("expose:close");
});

// Example Callbacks
/*
$("#Popup").on("expose:opened", function() {

  alert("Modal Opened!");
});

$("#Popup").on("expose:closed", function() {

  alert("Modal Closed!");
});
*/
  </script>

这是对的吗？

您的代码中有2个问题

用于$trigger的选择器抛出错误 - 您的控制台中有VM736 jquery.js:1502 Uncaught Error: Syntax error, unrecognized expression: a[href=#Popup]

$trigger = $('a[href="' + this.selector + '"]')

$model和close按钮的点击处理程序也阻止了提交按钮点击事件的默认操作

  $modal.on("click", function(e) { //instead of $modal.add($modal.find(".close")).on("click", function(e) {
    if ($(e.target).is($modal) || $(e.target).is('.close')) {
      e.preventDefault();
      $modal.trigger("expose:close");
    }
  });
