如何在HTML iFrame中检测滚动条的存在(使用Javascript)？
我已经尝试过了:
var vHeight = 0;
if (document.all) {
if (document.documentElement) {
vHeight = document.documentElement.clientHeight;
} else {
vHeight = document.body.clientHeight
}
} else {
vHeight = window.innerHeight;
}
if (document.body.offsetHeight > vHeight) {
//when theres a scrollbar
}else{
//when theres not a scrollbar
}
我也尝试过:
this.scrollLeft=1;
if (this.scrollLeft>0) {
//when theres a scrollbar
this.scrollLeft=0;
}else{
//when theres not a scrollbar
return false;
}
没有成功..
我在DOM Inspector上搜索了javascript objets,但没有找到任何内容.
是否可以在javacscript中检测iframe中的滚动条存在？
iframe内容来自同一个域.
直到现在都没有成功..
我想要的是:
这只能用CSS和HTML(没有任何javascript)吗？

托尼是一个论点
我的实际.htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /Servidor/agentesRainbow/
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /Servidor/agentesRainbow/index.php/$1 [L]

#This last condition enables access to the images and css folders, and …我遵循了基本的安装(http://railscasts.com/episodes/67-restful-authentication)
这样做:
1.)ruby脚本/生成经过身份验证的用户会话
2.)ruby脚本/生成经过身份验证的用户会话和 rake db:migrate
3.)在我包含的文件application_controler.rb上
include AuthenticatedSystem
4.)在我包含的文件routes.rb上
map.signup '/signup', :controller => 'users', :action => 'new'
map.login '/login', :controller => 'session', :action => 'new'
map.logout '/logout', :controller => 'session', :action => 'destroy'
map.activate '/activate/:activation_code', :controller => 'users', :action => 'activate', :activation_code => nil
问题是在localhost:3000 /看起来和通常一样 "欢迎你乘坐Ruby on Rails!"页面.
如何将登录页面显示在localhost:3000上？
例如,如果我在表单中选择[URL值],将[URL值]保存在数据库中,然后在如下页面中使用它:
<a href="[URL value]" > The Link </a>
如何防止此[URL值]:
http://www.somelink.com"> Evil text or can be empty </a> ALL THE EVIL HTML I WANT <a href="
如何保护URL表单文件的这种HTML注入,而不会破坏URL,以防它有效？
