尝试在JavaScript中使用SessionStorage
我试图每次会话只显示一次弹出窗口。为了实现这一点,我正在使用SessionStorage函数。但是,每当我重新加载网页时,弹出窗口都会显示。你能让我知道我在哪里犯错吗?
dialogue = new IMu.App.Dialogue();
dialogue.setHtmlMessage(IMu.string('dialogue-heading'));
dialogue.show({ showDetails: true });
window.sessionStorage.setItem('message','true');
var is_dialogue = window.sessionStorage.getItem('message');
if (is_dialogue != 'true')
{
dialogue.show();
}
以下是显示功能
show: function(options, callback)
{
if (typeof(options) == 'function')
{
callback = options;
options = undefined;
}
var test = jQuery('body').children('div.imu-dialogue');
jQuery('body').children('div.imu-dialogue').remove();
var owner = self.owner = jQuery('body').child('div', 'imu-dialogue');
var box = owner.child('div', 'box');
var message = box.child('div', 'message');
if (this.message)
{
var value = this.message.value;
var method = this.message.type;
message[method](value);
}
if (self.details)
{
var details = box.child('div', 'details');
for (var i in self.details)
{
if (! self.details.hasOwnProperty(i))
continue;
var detail = details.child('div', 'detail');
var value = self.details[i].value;
var method = self.details[i].type || 'text';
detail[method](value);
}
var show = box.child('div', 'show-details');
if (! options || options.showDetails !== true)
{
show.text('Details');
details.hide();
}
else
{
details.show();
show.text('I agree');
}
show.on('click', function()
{
self.owner.remove();
});
}
I'm trying to show a popup window only once per session. In order to achieve that I'm using sessionStorage function. however, the popup is showing up whenever I reload the web page. Can you please let me know where I'm making the mistake.
dialogue = new IMu.App.Dialogue();
dialogue.setHtmlMessage(IMu.string('dialogue-heading'));
dialogue.show({ showDetails: true });
window.sessionStorage.setItem('message','true');
var is_dialogue = window.sessionStorage.getItem('message');
if (is_dialogue != 'true')
{
dialogue.show();
}
Below is the show function
show: function(options, callback)
{
if (typeof(options) == 'function')
{
callback = options;
options = undefined;
}
var test = jQuery('body').children('div.imu-dialogue');
jQuery('body').children('div.imu-dialogue').remove();
var owner = self.owner = jQuery('body').child('div', 'imu-dialogue');
var box = owner.child('div', 'box');
var message = box.child('div', 'message');
if (this.message)
{
var value = this.message.value;
var method = this.message.type;
message[method](value);
}
if (self.details)
{
var details = box.child('div', 'details');
for (var i in self.details)
{
if (! self.details.hasOwnProperty(i))
continue;
var detail = details.child('div', 'detail');
var value = self.details[i].value;
var method = self.details[i].type || 'text';
detail[method](value);
}
var show = box.child('div', 'show-details');
if (! options || options.showDetails !== true)
{
show.text('Details');
details.hide();
}
else
{
details.show();
show.text('I agree');
}
show.on('click', function()
{
self.owner.remove();
});
}

您的逻辑向后。您需要检查
sessionstorage
项目是否已设置为 first 。如果尚未设置,请显示对话框然后设置。无需检查存储属性的值。简单地测试其存在就足够了。
You've got your logic backwards. You need to check if the
sessionStorage
item has been set first. If it has not been set, show the dialog and then set it.There is no need to check the value of the stored property. Simply testing for it's existence is enough.
忘记
dialogue.show();
如果在浏览器的新选项卡中尝试以下代码:
刷新页面并运行,
您可能会在代码whick whick whick whick whick section storage上存储在安装或创建的上?
Forget the
dialogue.show();
If you try in a new tab of your browser the following code:
refresh the page and run
You may have something in your code whick clean session storage on mounted or on created ?
