当页面滚动到 50px 时弹出模态框

Question

当用户点击关闭弹出窗口后，当点击弹出窗口关闭时，我使用 cookie 存储值，弹出窗口不应再次显示。但我在这方面遇到了问题。每当我滚动时，弹出窗口就会打开，即使我已经关闭它。

$('#fsModal').on('hidden.bs.modal', function (e) {
        $.cookie('close_popup' , '10' ,  { expires : 7 });
    });

    var scroll_function = getCookie("close_popup");

    $(window).scroll(function(){
        if (scroll_function == " ") {
            if ($(this).scrollTop() >= 50) {
                $("#fsModal").modal('show');
            }
        }
    });

Answer 1

您可能想尝试一下，为什么要为此使用 cookie？

var ClosePopUp = false;

$('#fsModal').on('hidden.bs.modal', function (e) {
      ClosePopUp = true;
    });


    $(window).scroll(function(){
            if ($(this).scrollTop() >= 50 && ClosePopUp == false) {
                $("#fsModal").modal('show');
            }else {
 $("#fsModal").modal('hide');
}
    });

Answer 2

我为此使用了 jQuery 插件（jQuery cookie），您可以从 https://github.com/js-cookie/js-cookie 获得相同的结果

在主页加载事件中首先将 cookie 设置为 false

 Cookies.set('ClosePopUp', 'false'); // set this only on home page load event

那么你需要在你的关闭模型上设置 Cookies

$('#fsModal').on('hidden.bs.modal', function (e) {
     Cookies.set('ClosePopUp', 'true');
    });

在你的卷轴上检查相同的

 $(window).scroll(function(){
            if ($(this).scrollTop() >= 50 && Cookies.get('ClosePopUp') != 'true' ) {
                $("#fsModal").modal('show');
            }else {
 $("#fsModal").modal('hide');
}
    });

最后在您的注销时删除 cookie..

Cookies.remove('ClosePopUp');

==== 为以前版本的 Cookies.js 编辑 =====

在主页加载事件中首先将 cookie 设置为 false

$.cookie('ClosePopUp', 'false',{ path: '/' }); // set this only on home page load event

那么你需要在你的关闭模型上设置 Cookies

$('#fsModal').on('hidden.bs.modal', function (e) {
      $.cookie('ClosePopUp', 'true',{ path: '/' });
    });

在你的卷轴上检查相同的

 $(window).scroll(function(){
            if ($(this).scrollTop() >= 50 && $.cookie('ClosePopUp') != 'true' ) {
                $("#fsModal").modal('show');
            }else {
 $("#fsModal").modal('hide');
}
    });

最后在您的注销时删除 cookie..

$.removeCookie('ClosePopUp');

试试这个：

HTML：

<input type="hidden" id="is_close" value="0">

<div id="dialog">

</div>

jquery：

$(window).on('scroll', function() {
    scrollPosition = $(this).scrollTop();
  if(scrollPosition > 50 && $('#is_close').val() == 0 )
  {
    $('#dialog').dialog({
      buttons: [
        {
          text: "Close",
          click: function() {
            $( this ).dialog( "close" );
            $('#is_close').val('1');
          }
        }
      ]
    });
  }
});
