I am using the following function in order to get recently closed sessions https://developer.chrome.com/extensions/sessions#method-getRecentlyClosed .
The docs say that I can pass a filter object with a property of maxResults in order to restrict the number of sessions return. I am not setting it over the supposed max of 25. But alas, code doesn't seem to work correctly; I'm expecting sessions array to contain 5 elements, but I still get 25 items ( I do get a response, it's just not being filtered properly).
// extension.js
// for now, hardcode limit of 5 for testing purposes
function getAllSessions(callback) {
chrome.sessions.getRecentlyClosed({maxResults: 5}, function(sessions) {
callback(sessions);
});
}
document.addEventListener('DOMContentLoaded', function() {
getAllSessions(function(sessions) {
console.debug(sessions)
});
});
simple html that loads the script
<html>
<head>
<script src="extension.js"></script>
</head>
<body>
</body>
</html>
Any ideas on what I'm doing wrong. I'm leaning towards this being an actual bug, but my favorite search engine doesn't have any results on this bug, or even a lot of people using this API.

I have a webpage that takes form details, POSTS the data and should then show the results. I'm using express for my routing.
This all works fine by resending the data with the HTML template after the POST but I think there must be a better way by hiding the "results" HTML section then just showing it once the data is known from the form. I've shown a cutdown version of my pages below.
On first load, the page says "your result is undefined", which I would expect but is ugly.
I could remove the "result" section and create a 2nd HTML page to resend from the POST route with it in which would work but I think there must be a better way.
I want to hide the result section on 1st page load then make it appear on the button submit with the result data. I can get the section hide/unhide but I can't get the data results back to display them. On button submit the form results just appear in the weburl www.mywebsite.com/?data almost like a GET request
I have tried using FormData and npm 'form-data' in a POST but can't get it working following these examples https://javascript.info/formdata and https://www.npmjs.com/package/form-data.
My structure in Node is
Router.js file
return res.send(htmlFormTemplate({}));
});
router.post('/css',
[],
async (req, res) => {
let {data} = req.body;
///
result= do some calculation on {data}
///
return res.send(htmlFormTemplate({result}));
});
The htmlFormTemplate is a js file
module.exports = ({result}) => {
return `
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form class="box" method ="POST">
<inputname="data" />
<button>Submit</button>
</form>
<script>
///tried form processing here
</script>
<section id="Results">
<ul><li>Your result is ${result}</li></ul>
</section>
</body>
</html>
`;
};
I'm self-taught and new so hope this makes sense and thanks for any help/ideas
You can check if the result variable is null before it gets to the section div:
${ result === null ? '' :
`<section id="Results">
<ul><li>Your result is ${result}</li></ul>
</section>`}
Like this, it wont show the result div if result if null.
There is a very simple to solve this problem,
just use some templating engine for ex EJS, its very easy to use and will help you better,
and your result is undefined because your using a promise and it might have happened that the response might have not come and you loaded the page. Just use await
return await res.send(htmlFormTemplate({result}));
I am fairly new to Grails and frameworks in general, so this is most likely a very basic problem. The only promising looking solutions I was able to find were working with the Tag, which is apparently deprecated in Grails 3. Similar questions do exist, but all from the time when was still a thing.
I am trying to program a way of displaying products that are grouped in subcategories which are then grouped in categories. When my page loads the subcategories and categories are requested from my database and selection options (Select-tag and checkboxes) are rendered in the view.
When one of the checkboxes representing the subcategories is checked i need to run a database query to get the product information and update an HTML-element by rendering a template for every row I get back. I have a controller action that does all that. My only problem is that I need a way to call the controller action whenever one of the checkboxes is checked.
I could maybe work around it by using actionSubmit and a hidden submit button that is clicked by javascript whenever a checkbox is checked, but that doesn’t seem like a proper solution.
I am probably missing some very basic functionality here but I did already thoroughly search and haven’t come across a proper solution by now, probably because I didn't use the right search terms. I would be so happy, if anyone could help me with this. Thanks a lot already!
The following example uses a javascript function activated in response to the checkbox being checked/unchecked, the value of which is passed to an action from which you can do whatever with the value of the checkbox, run your query etc. At present the action renders a template to update the view with the database results.
index.gsp
<!DOCTYPE html>
<html>
<head>
<meta name="layout" content="main" />
<script type="text/javascript">
$(document).ready(function(){
$( '#cb' ).click( function() {
var checked = $(this).is(":checked");
$.ajax( {
url: "/yourController/yourAction?checked=" + checked,
type: "get",
success: function ( data ) {
$( '#resultDiv' ).html( data )
},
error: function(jqXHR, textStatus, errorThrown) {
console.log( 'Error rendering template ' + errorThrown )
}
} );
})
});
</script>
</head>
<body>
<div id="resultDiv"></div>
<g:form>
<g:checkBox name="cb" />
</g:form>
</body>
YourController
class YourController {
def yourAction() {
// you may want to do something with the value of params.checked here?
def dbResults = YourDomain.getStuff()
render ( template: 'theTemp', model: [dbResults: dbResults] )
}
}
_theTemp.gsp
<table>
<caption>Table of stuff</caption>
<g:each in="${dbResults}" var="aThing">
<tr>
<td>${aThing}</td>
</tr>
</g:each>
</table>
The question: How get the unobtrusiv validation of a german date running in MVC?
Because I can't find a running example of using globalize 1.x with MVC 5 to validate a german date I needed two days to get it running.
The problems are the order of the js-files, getting the cldr-data and putting it all together in an way it can be reused.
In the answer I will show my current solution.
In this zip-file (https://www.dropbox.com/sh/75dx6alck7itwia/AABFkcgOQVc1bUXFE_jYfR_da?dl=0) you find all files you need.
It includes
an short todo.txt (de and en)
the cldr-data (jsons) in sub-directories
a custom HTML-Helper-class wich writes the needed HTML/js-Scripts to the view.
It seems, that rendering by the helper not allways works. So if there are problems with that, copy the code to every (edit / new) view.
<script src="~/Scripts/jquery.validate.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>
<script src="~/Scripts/cldr.js"></script>
<script src="~/Scripts/cldr/event.js"></script>
<script src="~/Scripts/cldr/supplemental.js"></script>
<script src="~/Scripts/cldr/unresolved.js"></script>
<script src="~/Scripts/globalize.js"></script>
<script src="~/Scripts/globalize/currency.js"></script>
<script src="~/Scripts/globalize/number.js"></script>
<script src="~/Scripts/globalize/date.js"></script>
<script src="~/Scripts/globalize/plural.js"></script>
<script src="~/Scripts/globalize/relative-time.js"></script>
<script src="~/Scripts/globalize/unit.js"></script>
<script src="~/Scripts/jquery.validate.globalize.js"></script>
<script>
$(document).ready(function () {
// Use $.getJSON instead of $.get if your server is not configured to return the
// right MIME type for .json files.
$.when(
$.get("/Scripts/cldr/main/de/ca-gregorian.json"),
$.get("/Scripts/cldr/main/de/numbers.json"),
$.get("/Scripts/cldr/supplemental/likelySubtags.json"),
$.get("/Scripts/cldr/supplemental/timeData.json"),
$.get("/Scripts/cldr/supplemental/weekData.json")
).then(function () {
// Normalize $.get results, we only need the JSON, not the request statuses.
return [].slice.apply(arguments, [0]).map(function (result) {
return result[0];
});
}).then(Globalize.load)
.then(function () {
Globalize.locale("de-DE");
});
});
</script>
I hope it helps.
This solution based on the answer to MVC 5 - can not get globalisation running.
If you want to use a bündle, see MVC 5, globalize, validate german date: How to bundle the js-scripts?
I don't know why but my layout is rendered two times.
Here is my index.html:
<head>
<title>title</title>
</head>
<body>
{{>layout}}
</body>
Here is my layout:
<template name="layout">
{{#if canShow}}
{{>Template.dynamic template=content}}
{{else}}
{{> loginButtons}}
{{/if}}
</template>
So here without route my template is display just one time.
Here is my route:
FlowRouter.route('/', {
action() {
BlazeLayout.render("layout", {
content: "home"
});
}
});
But with this route my template is display a second time.
This is my helpers, I think there is nothing to do with this problem but we never know.
Template.home.onCreated(function() {
this.autorun(() => {
this.subscribe('post');
});
});
Template.layout.helpers({
canShow() {
return !!Meteor.user();
}
});
Template.home.helpers({
cats() {
return Posts.find({});
}
});
you don't need to render layout in the body.
The router will take care of the rendering.
so, just have
<body>
</body>
or don't even have it at all.
Edit: Thanks to Keith, I have a better understanding of my problem. Here is his comment:
one thing to keep in mind, all the html you write in meteor isn't kept as html. It all gets converted to javascript. Things like index.html do not get pushed to the browsesr. Meteor just takes all the html you write converts it to javascript and renders what it needs to based on what your code says. This is how it knows todynamically change and rerender html
For things like changing title of the head or add meta etc, we can do it directely in the javascript.
ex: Meteor - Setting the document title
I have a show which displays a form with fields populated from a document. I'd like to change the values in the field and then save the updated document.
I'm having trouble finding a clear, concise example of how to do this.
Seriously, just finishing this example would work wonders for so many people (I'm going to leave a lot of stuff out to make this concise).
Install Couchapp
This is outside the scope of my question, but here are the instructions for completeness.
Create a couchapp
Again, this is kind outside the scope of my question. Here is a perfectly concise tutorial on how to create a couchapp.
Create a template
Create a folder in the root of your couchapp called templates. Within the templates folder create an HTML page called myname.html. Put the following in it.
<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<form method='post' action='#'>
<fieldset>
Hello <input type='text' name='name' value='{{ name }}'>
<input type='submit' name='submit' value='submit'>
</form>
</body>
</html>
Create a show
See the tutorial above for hwo to do this.
Add this code to a show called myname.
function(doc, req) {
if (doc) {
var ddoc = this
var Mustache = require("vendor/couchapp/lib/mustache");
var data = {
title: "The Name",
name: "Bobbert"
}
return Mustache.to_html(ddoc.templates.myname, data)
} else {
return ('nothing here baby')
}
}
Update the document with a new name by ...
So who can complete this step via both the client side and the server side?
Please don't point me to the guide, I need to read it in your words.
Thanks.
Edit:
Although the return value isn't pretty, just posting a form to the update handler will update the document.
You will probably want to look into update handler functions.
An update handler handles granular document transformations. So you can take 1 form, that has one distinct purpose, and only update the relevant fields in your document via the update handler.
Your update handler will need to take a PUT request from your form. A browser can't do this directly, so you'll need some javascript to handle this for you. If you're using jQuery, this plugin can take your form and submit it seamlessly via AJAX using PUT for you.
Inside the function, you can take the fields you are accepting, in this case name and apply that directly to the document. (input validation can be handled via the validate_doc_update function)
Update Handler (in your Design Document)
{
"updates": {
"name": function (doc, req) {
doc.name = req.form.name;
return [doc, "Name has been updated"];
}
}
}
HTML
<form id="myForm" action="/db/_design/ddoc/_update/name/doc_id">...</form>
JavaScript
$(document).ready(function() {
$('#myForm').ajaxForm({
type: "PUT",
success: function () {
alert("Thank you");
}
});
});
Once you've gotten this basic example up and running, it's not much more difficult to add some more advanced features to your update handlers. :)
