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 develop ASP.Net Core 2.1 RazorPages web application. I want parametrize the the value of asp-page tag helper.
So I use following code in cshtml file. There is a del_link local variable defined in begining of file. This variable is late used as parameter for second asp-page tag helper.
#page
#{
string del_link = "/UnloadDelete";
}
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
</head>
<body>
<div>
<a asp-page="/UnloadEdit">Details</a>
<a asp-page=#del_link>Delete</a>
</div>
</body>
</html>
ASP.Net Razor generate following HTML code.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
</head>
<body>
<div>
Details
Delete
</div>
</body>
</html>
As you can see in HTML code, asp-page="/UnloadEdit" is properly rendered to HTML code, but asp-page=#del not, it is rendered to <a href="">. How I can use local variable for asp-page tag helper in Razor Pages?
Thanks in advance.
You must pass a page name to the asp-page attribute. So what you are trying to do is not supported. If #del_link renders a relative URL, you can pass that to the href attribute instead. There may be other suitable solutions, depending on why you feel the need to use #del_link at all.
In PHP, it's easy to include a file in another one to avoid redundancy of the code using the include keyword. Is there a similar solution in Node.JS using Handlebars.JS?
From your question it sounds like you are looking for handlebars partials. For an example check out https://github.com/donpark/hbs/tree/master/examples/partial.
In short, you'd have something which looked like:
index.hbs:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Your Website</title>
</head>
<body>
{{> header}}
</body>
</html>
where {{> header}} is referencing the header.hbs partial.
In Jade JS, it's very easy to extend a layout. Supposed one have layout.jade, and for the index.jade, just do:
extend layout
block content // content comes here
Then it's pretty sufficient.
I searched the official guide but didn't found how to do. The most similar seems to be something like:
{>partials}
But still that's not extending a layout. How to achieve similar thing in DustJS?
Thanks a lot.
I found the solution... turns out I didn't read the dust documents careful enough.
Layout File:
<html>
<head>
<title>{+title}Location of Title{/title}</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.js"></script>
<link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.css" rel="stylesheet">
<script src="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.js"></script>
</head>
<body>
<header>
<h1 id="page-title" class="very-middle">{+title}Title Comes Here{/title}</h1>
</header>
<div id="content">
{+content}
Content Comes Here
{/content}
</div>
</body>
</html>
Content File:
{>layout/}
{<content}
{!
Content simply comes here
}
{/content}
So the point is the use of {+placeHolder}, {>toExtend} and {
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.
I am currently playing around with JSFs ClientBehavior API.
I want to create a client behavior that uses jQuery. Besides inclusion of the *.js files for jQuery another script will be required in the <head> section to bootstrap all the jQuery stuff i.e. create client side widgests.
I tried to follow this approach from victor herrera, but the component system event is never processed. I guess this is because ClientBehaviors do not inherit from UIComponent.
So my question is how to add dynamically created JS to the <head> of the rendered document.
This is what the rendered output in the end should look like:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script type="text/javascript">
$(document).ready(function () {
// Dynamically created stuff here
}
</script>
</head>
<body>
...
<input type="text" id="myJSFInputWithClientBehavior" onclick="doSomeStuffWithjQuery()" />
</body>
</html>
