I have this string: https://2352353252142dsbxcs35#github.com/happy.git
I want to get result: https://github.com/happy.git (without random string after second / and after # but without #).
Now I have something like this:
var s = 'https://2352353252142dsbxcs35#github.com/happy.git';
var d = s.substring(s.indexOf('/')+2, s.indexOf('#')+1;
s = s.replace(d, "");
it works, but I know it's an ugly solution.
What is the most efficient and more universal solution?
Try this:
const indexOfAtSign: number = receivedMessage.indexOf('#')+1
const httpsString: string = 'https://'
const trimmedString: string = s.slice(indexOfAtSign)
const requiredURL: string = httpsString.concat(trimmedString)
// Print this value of requiredURL wherever you want.
So here what my code does is, it gets position of # and removes everything before it along with the sign itself. Then using the slice() function, we are left with the remaining part which I named as trimmedString. Now I have pre-defined the `https string, anf we just need to merge them now. Done :-)
I had tried this out in my telegram bot and here's how it works:

First time posting here. I'm an experienced coding, but it's been a long time since I've done any, and I'm starting back up with App Script, a new language for me. I'm trying to do some basic stuff with text found within cells in a Google sheets. I've gotten it to work well enough, but I think my code can be simplified and improved if I learn a little bit more about working with text strings in App Script.
This is a very simplified version of my function. My real function finds the page numbers given in a citation in one cell, and puts just those page numbers in another cell. For the purposes of this question, I've simplified it to retrieve the text from the current cell, remove the first blank space in the text, count the numbers at the beginning of the text, and then write just those numbers into the current cell. It does what it is supposed to do, and what I need it to do, but I have so many questions! Thank you!!
function myFunction() {
var spreadsheet = SpreadsheetApp.getActive(); var
currentCell = spreadsheet.getCurrentCell().activate();
var style = SpreadsheetApp.newTextStyle().setForegroundColor('#000000').build();
var textString = currentCell.getRichTextValue().getText();
var count = 0;
var char = textString.substring(count,count+1);
textString = textString.replace(" ","");
while(char<10)
{
count = count+1;
char = textString.substring(count,count+1);
}
var numbers = textString.substring(0,count);
currentCell.setRichTextValue(SpreadsheetApp.newRichTextValue().setText(numbers)
.setTextStyle(1, count, style).build());
};
In retrieving my textString, is there a way to do it without using "getRichTextValue()"?
In writing the new text (numbers), is there a way to do that without using "setRichTextValue()"? And to do it without specifying the style?
In my while loop, I use char<10. This works, but I'm not sure why. char is a one character string, right? The character is a number, but I am thinking I shouldn't be able to compare with a number because it's a string? Also, it actually lets blank spaces through as well, so I know something is wrong. What can I do instead?
How can I get the replace function to remove ALL the blank spaces in my textString?
Here is a modified version of your script using Regex.
The reason your code char<10 works is it is comparing the ASCII value of the character with A being 10 and 0 to 9 being ASCII value 0 to 9.
function myFunction() {
var spreadsheet = SpreadsheetApp.getActive();
var currentCell = spreadsheet.getCurrentCell(); // returns a range, no need to activate
var textString = currentCell.getValue();
// use reges to remove all blank spaced
textString = textString.replace(/\s/g,"");
// use regex to get the first string of digits
// match returns an array so we need the first element of the array
var numbers = textString.match(/\d+/)[0];
currentCell.setValue(numbers)
}

I'm trying to read any message sent on a discord server and send a reply if a certain string is within the message ignoring all spaces and capitals. I'm very new to javascript and this is the first code I'm making just for fun.
This is the current main part of the code.
if(msg.content.toLowerCase().includes('string'))
{
msg.channel.send(emoji("480351478930866179"));
}
You can remove whitespace with replace() and shift the string to lowercase using toLowerCase() to achieve the desired result.
const original = 'Hello there.';
const str = original.replace(/\s/g, '').toLowerCase();
if (str.includes('hello')) console.log('Hi.');
You could use the string.replace method or you could use split then join. To ignore case just use toLowerCase();
Thank's, that solved my problem.
const original = 'Hello there.';
const str = original.replace(/\s/g, '').toLowerCase();
if (str.includes('hello')) console.log('Hi.');
In sourceConfigPath variable, it has a path like "conf/test.json", or it might have another layer, like "test/conf/test.json". I want to get the "test.json" part only.
I tried the indexOf function to get the position, then use either slice or substr function to get the 'test.json' part. But it always return 0 when do indexOf.
Can anyone please help here? many thanks!
var position = sourceConfigPath.indexOf('conf');
var newsourceConfigPath = sourceConfigPath.slice(position+4);
Or is there any better way to do this? Many thanks!
The best way is to use path.basename
The path.basename() methods returns the last portion of a path,
similar to the Unix basename
const path = require('path');
const newSource = path.basename('conf/test.json'); // test.json
You can use lastIndexOf instead of indexOf, but path.basename is recommended.
const filepath = '/path/to/file.json';
const position = filepath.lastIndexOf('/') + 1; // +1 is to remove '/'
console.log(filepath.substr(position));
I have a string ="/show/search/All.aspx?Att=A1". How to get the last value after the 'Att=' in efficient way ?
You could do a split on the '=' character.
Example (in C#):
string line = "/show/search/All.aspx?Att=A1";
string[] parts = line.Split('=');
//parts[1] contains A1;
Hope this helps
If you're only dealing with this one URL then both of the other answers would work fine. I would consider using the HttpUtility.ParseQueryString method and just pull out the item you want by key.
Whatever an
efficient way
is...
Try this:
var str = "/show/search/All.aspx?Att=A1";
var searchString = "Att=";
var answer = str.Substring(str.IndexOf(searchString) + searchString.Length);
I am currently working on a project that dynamically displays DB content into table.
To edit the table contents i am want to use the dynamically created "string"+id value.
Is there any way to retrieve the appended int value from the whole string in javaScript?
Any suggestions would be appreciative...
Thanks!!!
If you know that the string part is only going to consist of letters or non-numeric characters, you could use a regular expression:
var str = "something123"
var id = str.replace(/^[^\d]+/i, "");
If it can consist of numbers as well, then things get complicated unless you can ensure that string always ends with a non-numeric character. In which case, you can do something like this:
var str = "something123"
var id = str.match(/\d+$/) ? str.match(/\d+$/)[0] : "";
(''+string.match(/\d+/) || '')
Explanation: match all digits in the variable string, and make a string from it (''+).
If there is no match, it would return null, but thanks to || '', it will always be a string.
You might try using the regex:
/\d+$/
to retrieve the appended number
