设置Cookie并使用JavaScript获取Cookie
我试图根据我在HTML中选择的CSS文件来设置Cookie。我有一个带有选项列表的表单,以及不同的CSS文件作为值。当我选择一个文件时,应将其保存到Cookie大约一周。下次打开HTML文件时,它应该是您选择的上一个文件。
JavaScript代码:
function cssLayout() { document.getElementById("css").href = this.value;
}
function setCookie(){
var date = new Date("Februari 10, 2013");
var dateString = date.toGMTString();
var cookieString = "Css=document.getElementById("css").href" + dateString;
document.cookie = cookieString;
}
function getCookie(){
alert(document.cookie);
}
HTML代码:
<form> Select your css layout:<br>
<select id="myList">
<option value="style-1.css">CSS1</option>
<option value="style-2.css">CSS2</option>
<option value="style-3.css">CSS3</option>
<option value="style-4.css">CSS4</option>
</select>
</form>
回答:
我发现以下代码比其他任何代码都简单得多:
function setCookie(name,value,days) { var expires = "";
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days*24*60*60*1000));
expires = "; expires=" + date.toUTCString();
}
document.cookie = name + "=" + (value || "") + expires + "; path=/";
}
function getCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
function eraseCookie(name) {
document.cookie = name+'=; Max-Age=-99999999;';
}
现在,调用函数
setCookie('ppkcookie','testcookie',7);var x = getCookie('ppkcookie');
if (x) {
[do something with x]
}
