问题描述
我正在为我的网站制作后台更改脚本.除了应该存储所需值的cookie之外,其他所有东西都可以正常工作.我正在使用jQuery 1.3. IE 8说:对象在第47行上不支持此属性或方法char 118567432"!任何帮助将不胜感激.没有Cookie的工作示例:
I'm making background changing script for my site. Everything works fine except the cookie which should store the required value. I'm using jQuery 1.3. IE 8 says: 'object doesn't support this property or method on line 47 char 118567432'!? Any help will be greatly appreciated. Working example without cookie:
function images(which,image) {
if (which == 't1')image = images[0];
else if (which == 't2')image = images[1];//and etc...
}
$('html').css("background-image", image);
带有Cookie的示例(不起作用):
Example with cookie (not working):
function images(which,image) {
if (which == 't1')image = images[0];
{$.cookie("html_img", "" + image + "", { expires: 7 });
imgCookie = $.cookie("html_img");}
else if (which == 't2')image = images[1];
{$.cookie("html_img", "" + image + "", { expires: 7 });
imgCookie = $.cookie("html_img");}
}
$('html').css("background-image", imgCookie);
推荐答案
我已将您的代码转换为更有效且在语法上有效的JavaScript代码.
I've converted your code to a more efficient, and syntactically valid JavaScript code.
function images(which){
var image = /^t\d+/i.test(which) ? images[which.substr(1)-1] : null;
if(image !== null) {
$.cookie("html_img", image, {expires:7})
} else {
image = $.cookie("html_img");
if(!image) image = images[0]; //If the image doesn't exist, use default=0
}
$('html').css("background-image", image);
}
$(document).ready(function(){
images(); //Load image default from cookie
}
//If you want to change the image+cookie: images("t2");
