[英]Show/hide a div using cookies
I'm trying to show and hide a div using cookies. 我正在尝试使用cookie显示和隐藏div。 I'm using the jQuery cookie plugin.
我正在使用jQuery cookie插件。 While doing this the div I want to hide does not hide, it stays visible.
在执行此操作时,我要隐藏的div不会隐藏,而是保持可见状态。
As you can see in the code I'm setting a cookie with a button in the div with the id eerst
. 正如您在代码中看到的那样,我正在使用ID为
eerst
的div中的按钮设置cookie。 After this the page needs to be reloaded and the eerst
div needs to be hidden and then the div with the id choicea
needs to be shown. 此后,需要重新加载页面,并且需要隐藏
eerst
div,然后需要显示ID为choicea
的div。 I already tried different methods doing this, but it hasn't been working for me yet. 我已经尝试过其他方法来执行此操作,但是它尚未对我起作用。
<div id="eerst" class="container">
<div class="row center">
<h5 class="header col s12 light">Aflevewring 1</h5>
<video width="400" controls>
<source src="video\ryan.mp4" type="video/mp4">

</div>
<div class="row center">
<form id="Test" action='' method='post'>
<a type="submit" href="." name="On" onClick="SetCookie('choice1','choicea','1' )" class="waves-effect waves-light btn-large red darken-4">choice 1</a>
<a type='submit' name="Off" class="waves-effect waves-light btn-large red darken-4">choice 2</a>
</form>
</div>
</div>
<div id="choicea" class="container">
<div class="row center">
<h5 class="header col s12 light">Aflevewring 1</h5>
<video width="400" controls>
<source src="video\some.mp4" type="video/mp4">

</div>
<div class="row center">
<form id="Test" action='' method='post'>
<a type="submit" href="." name="On" onClick="SetCookie('choice2','choice2','1' )" class="waves-effect waves-light btn-large red darken-4">choice 1</a>
<a type='submit' name="Off" class="waves-effect waves-light btn-large red darken-4">choice 2</a>
</form>
</div>
</div>
function SetCookie(c_name, value, expiredays) {
var exdate = new Date();
exdate.setDate(exdate.getDate() + expiredays);
document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ? "" : ";expires=" + exdate.toGMTString())
}
$(document).ready(function() {
if ($.cookie('choice1') == "choicea") {
$("#choicea").show();
$("#eerst").hide();
} else {
$("#choicea").hide();
}
});
store the variable in cookie and get the cookie value, check for the string correctness and show/hide the div. 将变量存储在cookie中并获取cookie值,检查字符串的正确性并显示/隐藏div。 As show in the code below
如下面的代码所示
var login_cookie = [];
login_cookie.push(your_variable);
var data_in_cookie = JSON.stringify(login_cookie);
setCookie("cookie_name", data_in_cookie, 1);
function SetCookie(c_name, value, expiredays) {
var exdate = new Date();
exdate.setDate(exdate.getDate() + expiredays);
document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ? "" : ";expires=" + exdate.toGMTString())
}
function getCookie(cname) {
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
$(document).ready(function() {
var cookie_string = JSON.parse(getCookie("cookie_name"));
var check_cookie_value = cookie_string[0];
if (check_cookie_value == "choicea") {
$("#choicea").show();
$("#eerst").hide();
} else {
$("#choicea").hide();
}
});
