I am trying to change my html title depending on the partial that I load for the body.
Parent html:
<!DOCTYPE html>
<html lang="en">
<head>
<title>
{{title}}
</title>
</head>
<body>
{{>body}}
</body>
</html>
Partial body.hbs file:
<h1 id="brick-mason">Brick Mason</h1>
<h3 id="what-is-a-brick-mason-">What is a brick mason?</h3>
<p>Brick masons use various stones, concrete and bricks to build walls, walkways, fences, and other structures.</p>
What can I change so that my partial can determine what the title on my main html page displays?
you can do it easily with JavaScript,
just add in the body.hbs :
<script> document.title = 'the title here ' </script>
What I ended up doing was including a second partial in the handlebars file and then splitting them out in the grunt file config.
gruntfile.js
file_context: function(src) {
var fileName = path.basename(src).split(".")[0];
var obj = glob.route[fileName];
var fileString = fs.readFileSync("./" + src, "utf8").split("<split />");
return {
partials: {
header: fileString[0] || "",
body: fileString[1] || "",
},
src: 'src/base.hbs',
dest: path.join('static', obj, 'index.html')
};
}
base.hbs
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="/css/index.min.css" />
{{>header}}
</head>
<body>
<div id="nav_background"></div>
<div id="main">
<div id="nav_bar">
<div class="nav left_nav">

</div>
</div>
<div class="markdown-body">
{{>body}}
</div>
</div>
</body>
</html>
In your Partial.hbs body add the script to manipulate the tags
<h1 id="brick-mason">Brick Mason</h1>
<h3 id="what-is-a-brick-mason-">What is a brick mason?</h3>
<p>Brick masons use various stones, concrete and bricks to build walls, walkways, fences, and other structures.</p>
<script>
const title = document.querySelector('title');
title.innerHTML = 'Partial';
</script>

I'm trying to make a weather app, and use the API from openweathermap, I copied the baseurl from the web like this but it's not currently working...
const api = {
key:"03173bc8739f7fca249ae8d681b68955"
baseurl:"https://home.openweathermap.org/api_keys"
}
const searchbox=document.querySelector('.search-box');
searchbox.addEventListener('keypress', setQuery)
function setQuery(evt){
if (evt.keyCode==13)
//getResults(searchbox.value)
console.log(searchbox.value)
}
So when I type in the search box, the console doesn't show anything...
This is my html file:
<!DOCTYPE html>
<html>

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<link rel="stylesheet" href="weather.css">

<body>
<div class="app-wrap">

</header>
<main>

Is there something wrong with the baseurl or something, can anybody tell me?
wrap the selector with " ";
const searchbox = document.querySelector(".search-box");
also correct your api obj:
const api = {
key: "03173bc8739f7fca249ae8d681b68955",
baseurl: "https://home.openweathermap.org/api_keys"
}
You missed to add single quote in querySelector.
const searchbox=document.querySelector('.search-box'); // Corrected
also you need to update the API object
const api = {
key:"03173bc8739f7fca249ae8d681b68955",
baseurl:"https://home.openweathermap.org/api_keys"
}
I have two html pages called home.html and about.html.
And I also have a js file called main.js which is linked with both of the html pages.I have a div with a class of "home" in home.html and another div with a class of "about" in about.html. Class "home" has a text and class "about" has a text too.Now I slected them in my main.js file like this,
const home = document.querySelector('.home')
const about = document.querySelector('.about')
And manipulated them like this,
home.style.color = 'red'
about.style.color = 'green'
But the problem is only the variable 'home' is changing its color not the variable
'about'
I think there is maybe a particular way to select elements from multiple pages.
But if there is pls let me know bcz the variable 'about' is not getting manipulated with anything.
const home = document.querySelector('.home')
const about = document.querySelector('.about')
// Manipulated them like this
home.style.color = 'red'
about.style.color = 'green'

<div class="home"> HOME </div>
<script src="main.js"></script>
</body>
</html>
Rather than:
<div class="home"> HOME </div>
<div class="about"> ABOUT </div>
You can use a custom data attribute like data-page:
<div data-page="home"> HOME </div>
<div data-page="about"> ABOUT </div>
Then, if you want to do something more dynamic than straightforward CSS styling, you can script the following:
const myDiv = document.querySelector('[data-page]');
switch (myDiv.dataset.page) {
case ('home') : [... DO SOMETHING... ] ; break;
case ('about') : [... DO SOMETHING... ] ; break;
}
N.B. When using this setup, where you do only want to apply CSS styling, then definitely use CSS:
[data-page="home"] {
color: red;
}
[data-page="about"] {
color: green;
}

Hello i'm building an application where i want to dynamically change the source of an image in order to force reload it . The problem is that in order of this i only get a broken image on the browser. Instead , if a run the function manually by a button it runs perfect .

There are two solutions I've used for this in the past.
1) Use an ng-if/ng-show on your img tag. This will prevent the broken image from displaying.
<img ng-if='snapshot'>
2) Set a default image that will load and then be replaced once the other images load.
$scope.snapshot = 'snapshots/default.png';
I have a global view model which is applied to main div
and I have some other view models and I want to apply them to nested elements of my main div
but I am getting the
You cannot apply bindings multiple times to the same element.
and here it is a sample :

Please guide me with your brilliant solutions :)
Need to apply binding separately for both view modal
or can just create both property in same viewModal
Unfortunately, I am not sure to understand anything to java, jquery and all this kind of thing. Nevertheless, I am trying to get some inspiration on forums in order to make a personal website that contains a vertical navbar and a div container in which external html pages will be loaded. Each html file uses an html5 applet called JSmol, which plots 3D molecules that can be manipulated interactively. The main page looks like this:

Up to now, I have worked on the PG.html file (Point Group entry in the vertical menu), which works perfectly fine when it is loaded separately. But is not the case when it is loaded inside the main page as an external html page. The title is the only thing that appears, it seems that the jsmol application is not properly initialized. May be this is specific to the invocation of jsmol ; or is this a general issue when one wants to load hmtl files with embedded scripts ?
