Example 1: cm to inch 1 cm = 0.3937 inch Example 2: cm to inches 1 cm = 0.393701 inch Divide the cm value by 2.54. Example 3: cm to inches const cm = 1; console.log(`cm:${cm} = in:${cmToIn(cm)}`); function cmToIn(cm){ var in = cm/2.54; return in; }

Answer : Your problem lies in the ui-if part. Angular-ui creates a new scope for anything within that directive so in order to access the parent scope, you must do something like this: <textarea ng-model="$parent.noticeText"></textarea> Instead of <textarea ng-model="noticeText"></textarea> This issue happened to me while not using the ng-if directive on elements surrounding the textarea element. While the solution of Mathew is correct, the reason seems to be another. Searching for that issue points to this post, so I decided to share this. If you look at the AngularJS documentation here https://docs.angularjs.org/api/ng/directive/textarea , you can see that Angular adds its own directive called <textarea> that "overrides" the default HTML textarea element. This is the new scope that causes the whole mess. If you have a variable like $scope.myText = 'Dummy text'; in your controller and bind that to

Example 1: body-parser npm $ npm install body-parser Example 2: body-parser node // Express/Connect top-level generic // This example demonstrates adding a generic JSON and URL-encoded parser as a top-level middleware, which will parse the bodies of all incoming requests. // This is the simplest setup. var express = require('express') var bodyParser = require('body-parser') var app = express() // parse application/x-www-form-urlencoded app.use(bodyParser.urlencoded({ extended: false })) // parse application/json app.use(bodyParser.json()) app.use(function (req, res) { res.setHeader('Content-Type', 'text/plain') res.write('you posted:\n') res.end(JSON.stringify(req.body, null, 2))}) Example 3: body parser npm var bodyParser = require('body-parser')

Example 1: \ print('\\') Example 2: forward slash In case your keyboard is like mine: /

Answer : Note/Update (2021): While this answer works , philosophically I agree with other comments that the right way to do this is to ask Postgres . Check whether the other answers that have psql -c or --command in them are a better fit for your use case (e.g. Nicholas Grilly's, Nathan Osman's, bruce's or Pedro's variant I use the following modification of Arturo's solution: psql -lqt | cut -d \| -f 1 | grep -qw <db_name> What it does psql -l outputs something like the following: List of databases Name | Owner | Encoding | Collate | Ctype | Access privileges -----------+-----------+----------+------------+------------+----------------------- my_db | my_user | UTF8 | en_US.UTF8 | en_US.UTF8 | postgres | postgres | LATIN1 | en_US | en_US | template0 | postgres | LATIN1 | en_US | en_US | =c/postgres + | | |

Answer : I just had a similar problem. The same exception occurs when a Model has no parameterless constructor. The call stack was figuring a method responsible for creating a new instance of a model. System.Web.Mvc.DefaultModelBinder. CreateModel (ControllerContext controllerContext, ModelBindingContext bindingContext, Type modelType) Here is a sample: public class MyController : Controller { public ActionResult Action(MyModel model) { } } public class MyModel { public MyModel(IHelper helper) // MVC cannot call that { // ... } public MyModel() // MVC can call that { } } This can also be caused if your Model is using a SelectList, as this has no parameterless constructor : public class MyViewModel { public SelectList Contacts { get;set; } } You'll need to refactor your model to do it a different way if this is the cause. So using an IEnumerable<Contact> and writing an extension method that creates the

Answer : As content script has its own limitations, chrome.tabs is only available in background scripts and popup scripts. If you wanna to use chrome.tabs then pass message from content_script to background script and play with chrome.tabs . Content scripts have only limited access to Chrome APIs. This access does not include the API you are trying to use (e.g. chrome.tabs ). If you need to use that API, you will have to do so in a background script 1 . As listed in Chrome's content scripts documentation, the APIs available to a content script are [I have placed deprecated methods in strikethrough format]: extension ( getURL , inIncognitoContext , lastError , onRequest , sendRequest ) i18n runtime ( connect , getManifest , getURL , id , onConnect , onMessage , sendMessage ) storage A couple of the listed APIs are deprecated and have been for some time. Those that are deprecated have moved to different locations (also listed above): extension.onRequest ➞

Example 1: Cohen Sutherland Line Clipping Algorithm: In the algorithm, first of all, it is detected whether line lies inside the screen or it is outside the screen. All lines come under any one of the following categories: Visible Not Visible Clipping Case Cohen Sutherland Line Clipping Algorithm: In the algorithm, first of all, it is detected whether line lies inside the screen or it is outside the screen. All lines come under any one of the following categories: Visible Not Visible Clipping Case Example 2: cohen sutherland algorithm There are three possible cases for any given line. Completely inside the given rectangle : Bitwise OR of region of two end points of line is 0 (Both points are inside the rectangle) Completely outside the given rectangle : Both endpoints share at least one outside region which implies that the line does not cross the visible region. (bitwise AND of endpoints != 0). Partially inside the window : Both endpoints are in different regions. In this case
