In ASP.NET MVC 5, is it possible to use BundleColletion.UseCdn and have it render with the HTML integrity attribute? For example, is there someway to make this:
bundles.UseCdn = true;
bundles.Add(
new ScriptBundle("~/bundles/jquery", "https://code.jquery.com/jquery-3.1.1.min.js")
.Include("~/Scripts/js/jquery/jquery-3.1.1.min.js")
);
render as this?
<script
src="https://code.jquery.com/jquery-3.1.1.min.js"
integrity="sha256-hVVnYaiADRTO2PzUGmuLJr8BLUSjGIZsDYGmIJLv2b8="
crossorigin="anonymous"></script>
Partial answer.
To add crossorigin="anonymous" attribute you can use #Scripts.RenderFormat
#Scripts.RenderFormat("<script type=\"text/javascript\" src=\"{0}\" crossorigin=\"anonymous\"></script>", "~/bundles/jquery")
You also can include integrity="sha256-hVVnYaiADRTO2PzUGmuLJr8BLUSjGIZsDYGmIJLv2b8=" part in RenderFormat, but it does not look like a good solution.
I tried this way in our ASP.NET MVC 5 project when CDN fails
#Scripts.RenderFormat("<script src='{0}' integrity='sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa' crossorigin='anonymous'></script>", "~/bundles/bootstrapJS")
And this will generate (inside developer tool),
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>
And From this answer we found that there is bug if script is fail to load from CDN
So we add script manually inside the tag.
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>(window.jQuery) || document.write('<script src="/Scripts/jquery-1.12.4.min.js"><\/script>');</script>
</head>
<body></body>
</html>
You can have it like
<script src='#Scripts.Url("~/bundles/jquery")' crossorigin="anonymous" integrity="value"> </script>

Using ufront and erazor I ran into the following problem very quickly.
The hello-world example provides the following layout:
<!DOCTYPE html>
<html lang="en">
<head>
<title>#title</title>
<meta charset="utf-8" />
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" />
</head>
<body>
<div class="container">
#viewContent
</div>
</body>
<script src="//code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"</script>
</html>
For certain pages I want to add more headers or scripts after Jquery has been loaded.
One way to do so (for the scripts for example), would be to pass the scripts as an array of strings, and construct them on the layout file :
...
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"</script>
#for(script in scripts) {
<script src='#script.path'></script>
}
</html>
....
The problem with this approach is that I can't keep meaningful headers + body + scripts on the same template file witch would be great, also needs extra care to pass the scripts and headers as context.
Some template engines like Razor or Laravel allow to do that using 'sections'.
Is it possible to do something similar with erazor? If not what would be a good alternative?
I'm looking for alternatives to Jade templates in express 4.x because I really don't like Jade's syntax. I'm tending towards EJS, because it's basically just HTML on steroids.
However, one really nice feature of Jade templates is the ability to use layouts. I've found https://www.npmjs.org/package/express-ejs-layouts, but it seems to be made for express 3 and its build is failing :/.
I also found https://www.npmjs.org/package/ejs-mate which is made for express 4.x but it only seems to support a single content block (body).
I would like to have something like this:
layout.something:
<html>
<head>
<% block styles %>
<% block scripts %>
</head>
<body>
<% block body %>
</body>
</html>
index.html:
uses layout "layout.somehing"
scripts:
<script src="my_custom_script.js"></script>
styles:
<link rel="stylesheet ...></link>
body:
<h1>This is my body!</h1>
So that this yields:
<html>
<head>
<link rel="stylesheet ...></link>
<script src="my_custom_script.js"></script>
</head>
<body>
<h1>This is my body!</h1>
</body>
</html>
Does anyone know an engine that is capable of that besides Jade?
You can try express-handlebars, it supports layout and partial views.
Alright, my question is pretty simple. Suppose I have a homepage that is not linked to any external stylesheets, all its styles being either inline or internal, how do I do so that AFTER the homepage has been downloaded and displayed, the browser then downloads any necessary (specified) external stylesheets. Is this possible?
Thank you.
Try This:
<head>
<script type='text/javascript'>
function addstyle()
{
document.getElementById('style').href='style.css';
}
</script>
<link rel="stylesheet" type="text/css" href="">
</head>
<body onload="addstyle()">
<h1>Welcome</h1>
<p>Hello whats up</p>
<p>Hope you will have a great day</p>
</body>
I am new to meteor and I am trying to do multi-page application where http://www.mydomain.com/page1 will result a totally different page from http://www.mydomain.com/page2.
By totally different I mean that I don't want the page to be rendered by the client.
I tried to use meteor-router but What I got is something like:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="/myapp.css?9297ad4aa173c4e0c19aebd27c62a5c43242bb93">
<script type="text/javascript">
__meteor_runtime_config__ = {"ROOT_URL":"http://localhost:3000","serverId":"iMp4kgzzeqDtktJoY"};
</script>
<script type="text/javascript" src="/packages/underscore/underscore.js?6d71e6711255f43c0de8090f2c8b9f60534a699b"></script>
<script type="text/javascript" src="/packages/meteor/client_environment.js?07a7cfbe7a2389cf9855c7db833f12202a656c6b"></script>
<script type="text/javascript" src="/packages/meteor/helpers.js?2968aa157e0a16667da224b8aa48edb17fbccf7c"></script>
...
...MANY MANY MANY SCRIPTS.... ?!?
...
...
<script type="text/javascript" src="/myapp.js?2866dcdb5c828b129cdd3b2498a4bf65da9ea43f"></script>
<title>myapp</title>
</head>
<body>
</body>
</html>
And this is not what I want. I want page1 route will return me:
<!DOCTYPE html>
<html>
<head>
My meta tags
</head>
<body>
page1
</body>
</html>
And I want page2 to return different meta tags with different content.
In order to be clear, lets assume that my clients sometime doesn't have javascript. I don't asking about whether meteor is the right framework! I am asking only if can I do this with meteor.
Meteor works a bit different compared to the traditional LAMP stack. Basically it works by patching out the DOM to only where the changes are needed as opposed to re-downloading the whole web page. It makes for a very satisfying end user experience on modern web browsers.
To use meteor router you need to find a spot that you want to patch out with new data for different pages with {{renderPage}}. You can use something like
<head>
<title>xx</title>
</head>
<body>
{{renderPage}}
</body>
<template name="page1">
<h2>Hello!</h2>
</template>
<template name="page2">
<h2>Ola!</h2>
</template>
Now you need to define a router in your client side javascript:
Meteor.Router.add({
'/page1': 'page1',
'/page2': 'page2'
});
So if you load /page1 you would see Hello! and if you load /page2 you would see Ola! as defined in the <template name="page2">..</template>
With the meta tags you need to use javascript to create them. With something like
$('head').append("<meta...");
Again this depends on your preference, personally I find these type of apps load ridiculously fast between web pages as compared to other 'thin' based websites. (Have a look at meteor.com to see how fast you can swap between the pages). The browser does need javascript, however.
Of note is in production mode there will only be 1 script tag.
After struggling for 2 days i am still not able to integrate node+express+boilerplate and a simple JQuery module (Date Picker).
As a final check, i cloned the fresh copy of this project and added the below 4 lines. It failed to show the date prompt which confirmed that the problem isn't at my end. The same 4 lines of code on normal html project works.
I decided to give up on this but there should be a reason why it is not working. I am still not able to figure it out.
Project to clone: https://github.com/mape/node-express-boilerplate
Add these 4 lines to layout.ejs under view directory to head element.
<link rel="stylesheet" type="text/css" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/themes/smoothness/jquery-ui.css" media="all">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"></script>
<p>Date: <input type="text" id="datepick"></p>
<script type="text/javascript">
$(function() {
$("#datepick").datepicker();
});
</script>
You added the paragraph html element to the element as well? If so, try moving that inside the <body> tag somewhere, like the views/index.ejs file.
