I need to to search through the document text and where it finds a pattern of 0000/0, 0000/00 or 0000/000 (where 0 can be any number) it automatically wraps that text in
0000/00
What I found for auto linkers are only when text is a URL, so it doesn't really help with what I need.
A simple regex pattern would do the trick.
text.replace(/(0000\/[0-9]{1,3})/gm, `$1`);
This will look for 0000/ followed by numbers between 0 and 9, 1 to 3 times.
simple regexp approach
document.body.innerHTML = document.body.innerHTML.replace(/(\d{4}\/\d{1,3})/g,
'$1')
Some text 0000/0 and this 1234/56 and that 7777/666

I have a string that looks like "{`index`:`20`,`value`:`RA`}<1", and I want it to become "`RA`<1". I don't think the replace function is sufficient as the index and value changes based on what I enter. Is there a way to do that?
assuming the required string is everything after the last :, except for the }, the original string can be sliced and edited as follows:
const string = "{`index`:`20`,`value`:`RA`}<1";
let newString = string.slice(string.lastIndexOf(":")+1).split("}").join("");
console.log(newString);
This will always append everything after the final } to everthing before it but after the last :, regardless of the earlier content.

I have a data that looks like this
Huawei Y7P Art-L28 (4/64gb) (AAAAAAAAAAAAAA) EXP:02/19/2020
Huawei Y9 prime 2019 (BBBBBBBBBBBBBBB) EXP:07/17/2019
Oppo A31 4gb/128gb (CCCCCCCCCCCCCCC)
Vivo Y15 5000mah 4GB/64GB (1901) (DDDDDDDDDDDDDDD) EXP:06/14/2019
And the I want to get this data
AAAAAAAAAAAAAA
BBBBBBBBBBBBBBB
CCCCCCCCCCCCCCC
DDDDDDDDDDDDDDD
Basically what I want to happen is to extract the data from the set of word but my problem here is that its very unpredictable. It has no pattern at all so its hard to separate the string.
Assuming that you need a substring in last parenthesis:
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(column, '(', -1), ')', 1)
FROM source_table

I'm a complete newbie to programming and I wanna develop a one page-website that removes both numbers and this symbol ==> : from any given sentence.
Let's say you have the following:
(Hey Mr. 11, I'm 18, and I can't wait to turn 20, to own a :)
As you click generate you'd get the following results:
(Hey Mr., I'm, and I can't wait to turn, to own a)
How would you do that?
Here's a dead simple implementation in HTML/JavaScript that uses a regex replacement, to get you started.
document.getElementById('input').onkeyup = function() {
document.getElementById('output').textContent =
this.value.replace(/[0-9:]/g, '');
};
Remove numbers (0-9) and colons (:) from input.
<br>Input: <input type="text" id="input" />
<br>Output: <span id="output"></span>

I have a string like this: *ngIf="thisThing > 0"
Using RegEx, I'd like to select/return ONLY the > or in some cases, <.
I have the following expression: (?<=")(?:.*?)(<|>)(?:.*?)(?=") but this still selects everything inside the quotes. I only want to match that >.
I've been testing it here: https://regex101.com/r/4KPfbT/1
I guess you're over-complexifying it. Why not this way:
\w*=".*([<>]).*"
It works, take a look:
console.log('*ngIf="thisThing > 0"'.match(/w*=".*([<>]).*"/)[1])
console.log('whatever="otherThing < 999"'.match(/w*=".*([<>]).*"/)[1])

^[a-zA-Z]\w+#[a-zA-Z_]+?\.[a-zA-Z]{2,4}$
i had tried this regex for email but it allow following cases
123#mail.com
example.mail#mail.com
Here is the code which searches for the number at the start.
If number is matched it prints message in console.
let regex = /^[0-9]/;
let object = [{email:'123#mail.com'},{email:'example.mail#mail.com'}];
for(let i =0;i<object.length;i++){
if(object[i].email.match(regex)){
console.log('E-mail ',object[i].email,' is not valid.')
}
}
This is the used regex: ^[0-9]
