Added Dim es, fs but the result is the same. "The string is empty" for both cases

How do we check if a given string is empty or not? I've tried isNull, isEmpty as well as equal and non-equal signs, the results are the same for empty and filled texts. My code looks like this: Call am(es) Call am(fs) es = "" fs = "ms" Sub am(s) if s <> "" then response.write "The string is not empty <br>" else response.write "The string is empty <br>" end if end Sub

Wow, it works! But what if I am receiving a text from a <textarea>? Is it possible to somehow insert those literals, so that JS 'thought' it is an integral string?

Hello, iwato! Well, basically, my goal is to make some manipulations with a string variable and it's ok with relatively small single line strings. But when I copy and paste a text from a .txt file and assign it to str, of course, there is an error, because JS is a line-break sensitive. So, I want to make multiline text become single line string programatically. For example, paste it to a textarea and then take it as a string from there. This code doesn't change the string: var e = str.indexOf("/n"); if(e != -1){ // if we have at least one line break in str, replace /n with space str = str.replace(/n/g," "); }

My string variable is quite big and it contains line-breaks. I need to make it single lined to be detected by JS as usual string variable: initial condition: var str = "my string"; the string without line breaks: var str = "my string"; How can I detect those line breaks? By replacing '/n' symbols with spaces? Are there any other ways to deal with them?

That's right, thanks! Didn't think about it. All ingenious solutions are so simple

How to display a text as it is in HTML using only HTML tags? For example, I want special symbols like &amp; not to be interpreted by browser as &, but display as &amp; All I found is a deprecated <xmp> tag, it works, but it creates a new paragraph for every symbol.

Excellent! Thanks, Ingolme!

I tested the code on Firefox, but it also applies styles for the rest of the HTML file: <div> <style scoped> h1 {color:red;} p {color:blue;} </style> <h1>This is a heading</h1> <p>This is a paragraph.</p> </div> <h1>This is a heading</h1> <p>This is a paragraph.</p>

No, those were just interview tasks with strict condition to use JS or one of its frameworks. But I decided to show that data from a form can, indeed, be added using push() method for arrays, if the json structure is inside html file. It works well, however, of course, the json data is not changing physically.

May I refer to this topic, if an employer asks me to manipulate data from json file using javascript? Because it is already the second time they want me to do "something impossible"

Thanks, Ingolme

I know, but I have asked the same question on StackOverflow. Can you please consider their solution and advise me if there is a way to somehow use it in separate files? Here is the link: https://stackoverflow.com/questions/50590055/angularjs-inserting-data-to-a-json-file/50596513#50596513

I have 3 files: html that is displaying data from json file using AngularJS, json file containing the data, script.js that stores the scripts. HTML file also has a form, from which I want to add data to my json file (onsubmit="insertData()"). insertData function is going to be in script.js I know, I may use .push method for this, but I don't know how to apply to the json file in this case. script.js var prg = angular.module('ajsprogram', []); prg.controller("outercont", function($scope, $http) { //function to display json file information $http.get('airlines.json').success(function(data){ $scope.info = data; $scope.airlineorder = 'airline'; }); }); function newairline(an,hb,ur,cs){ //new function to insert a data } airlines.json [ { "airline" : "British Airways", "hub" : "LHR", "url" : "http://britishairways.com", "callsign":"SPEEDBIRD" }, { "airline" : "Air France", "hub" : "CDG", "url" : "http://airfrance.com", "callsign":"AIRFRANS" }, { "airline" : "Virgin Atlantic", "hub" : "LGW", "url" : "http://virginatlantic.com", "callsign":"VIRGIN" }, { "airline" : "RyanAir", "hub" : "DUB", "url" : "http://ryanair.com", "callsign":"RYANAIR" }, { "airline" : "Emirates", "hub" : "DXB", "url" : "http://emirates.com", "callsign":"EMIRATES" } ]

Exactly, I've just found it easier to check the scripts using command prompt, than a browser console. Thank you

Thanks, Ingolme. Let me extend my question then: is it possible to include one .js file in another one? Hypothetically. For example, because of the fact I have too much code in one file.

I like w3.css, it is very useful lightweight style extension, but never knew that there were w3.js. I have no doubts, that it is also very good frameworks, however, nowadays there are so many javascript libraries, you can choose whatever you like and that fits your needs.

How can I include AngularJS in JS file? Not in HTML, but in JS file. I read that it is possible to use "require" NodeJS command, to call Angular lib functions. This code generates an error ('window is not defined'): const ang = require('../lib/angular'); let myApp = ang.module("myApp", []); console.log(myApp); Is there a way to fully include it in a js file?

Ingolme thank you!

Sorry for stupid question. I can't understand the purpose of cloning an array in JS. Why do we need it? What is the difference between: let a = []; let b = a; and: let a = []; let b = a.slice(0);

If not first form is going to submit to a current tab, the solution will be more simple and elegant. We just paste this string in <head> : <base target="_blank"> Voila and all our submits give a new tab with the form results!

The task seems to be simple, but I can't solve it. Thanks in advance, Web supermen and ASP Gurus!

This property doesn't work in latest Firefox and Chrome. The information is contradictional: w3.org, msdn.microsoft.com and developer.mozilla.org have the information on this property, although I can't find it on w3schools, it also doesn't seem to be working on TryIt Editor Sandbox. Anyone has this feature working in any browser?

No, it submits to another URL, but do not shows data in a different tab
