Question

页面填完User和Email后，页面刷新后保存下来下来，不需要再输入一遍
图如下：

具体代码如下：

[color=red]//user name[/color]

[color=red]//email[/color]

如何添加 可以保存呢？

Answer 1

[code="java"]
function writeCookie(name, value, hours) {

var expire = "";

if(hours != null) {

expire = new Date((new Date()).getTime() + hours * 3600000);

expire = "; expires=" + expire.toGMTString();

}

document.cookie = name + "=" + escape(value)+ expire;

}

function readCookie(name) {

var cookieValue = "";

var search = name+ "=";

if(document.cookie.length > 0) {

offset=document.cookie.indexOf(search);

if (offset!=-1) {

offset += search.length;

end = document.cookie.indexOf(";",offset);

if (end== -1) {
end = document.cookie.length;

}
cookieValue = unescape(document.cookie.substring(offset, end));
}

}

return cookieValue;

}
