123456 12-12 3456
How do I automatically convert the text into the Textarea field?
123456 | 12 | 12 | 3456
automatically corrected.
How can I do this in Textarea?

You can attach a keyup event listener on your textarea and modifying it's content by splitting based on 1 or more non-digit characters and joining them with your desired pipe(|) symbol.
document.getElementById('some_id').addEventListener('keyup',function(){
var content = this.value.split(/[^\d]+/);
this.value = content.join(" | ");
});
<textarea rows='10' cols='50' id='some_id'>
</textarea>
Ok, so as discussed in the comments, for your credit card formatting, you can do something like below:
document.getElementById('some_id').addEventListener('keyup',function(){
var content = this.value;
var new_content = '';
var temp_content = '';
var current_length = 0;
for(var i=0;i<content.length;++i){
if('0123456789'.indexOf(content.charAt(i)) != -1){
temp_content += content.charAt(i);
current_length++;
}
if(current_length === 25){
new_content += insertPipeForCreditCardFormat(temp_content) + '\n';
temp_content = '';
current_length = 0;
}
}
this.value = new_content + temp_content;
});
function insertPipeForCreditCardFormat(credit_card){
var pipe_indices = new Set([16,18,22]);
var card_format = '';
for(var i=0;i<credit_card.length;++i){
if(pipe_indices.has(i)){
card_format += '|';
}
card_format += credit_card.charAt(i);
}
return card_format;
}
<textarea id='some_id' rows='10' cols='50'></textarea>

Use replace:
const str = "123456 12-12 3456";
const replaced = str.replace(/\-|\s/g, " | ");
console.log(replaced);

I would like to split a string between these ''' characters.
My string looks like this:
const str = " My random text '''tag1''' '''tag2''' ";
and the output should look like this: ["tag1", "tag2"]

Use a regular expression with a capture group and RegEx.exec() to extract any substrings between three apostrophes. The pattern uses lazy matching (.*?) to match any sequence of characters (including none) between the apostrophes.
const str = " My random text '''tag1''' '''tag2''' ";
re = /'''(.*?)'''/g;
matches = [];
while (match = re.exec(str)) {
matches.push(match[1]);
}
console.log(matches);
Output
[ 'tag1', 'tag2' ]

I think a short and sweet method would be :
var regex = /(?<=''')\w+(?=''')/mgi;
var matches = "My random text '''tag1''' '''tag2'''".match(regex);
with a result of : (2) ["tag1", "tag2"]
It matches everything between any occurence of '''.

You can use a function like this:
function getBetween(content, start, end) {
var result = [];
var r = content.split(start);
for (var i = 1; i < r.length; i++) {
result.push(r[i].split(end)[0]);
if (i < r.length - 1) { i++; }
}
return result;
}
Usage:
var result = getBetween(str, "'''", "'''");
which results in
["tag1", "tag2"]
Proof
const str1 = " My random text '''tag1''' '''tag2''' ";
const str2 = "String '''tag1''' this will work '''tag2'''.";
const str3 = "'''tag1''' '''tag2''' sup man '''tag3'''";
function getBetween(content, start, end) {
var result = [];
var r = content.split(start);
for (var i = 1; i < r.length; i++) {
result.push(r[i].split(end)[0]);
if (i < r.length - 1) { i++; }
}
return result;
}
var result1 = getBetween(str1, "'''", "'''");
var result2 = getBetween(str2, "'''", "'''");
var result3 = getBetween(str3, "'''", "'''");
console.log(result1);
console.log(result2);
console.log(result3);
Hope this helps

Try using template literal like below:
str.split(`'''`);
The result may look like this:
[" My random text ", "tag1", " ", "tag2", " "]
Hope this help ;)

cut the string from last '/' to '.html'
I have a string like that
"/Views/GS/stockView.html"
My need the name "stockView"
How can I cut the name from a string?
Thanks.

a = "/Views/GS/stockView.html";
a.split('/').pop().split(".")[0];
Demo

use indexOf() and lastIndexOf() method, like
var str = "/Views/GS/stockView.html";
var slashPos = str.lastIndexOf('/');
var dotPos = str.indexOf('.', slashPos + 1);
var result = str.substring(slashPos + 1, dotPos);

Try using RegExp:
var view = function(str) {
return str.match(/\/(\w*)\./)[1];//finds a word between `/` and `.`
};
console.log(view("/Views/GS/stockView.html"));
console.log(view("/Views/fs/inventView.html"));
console.log(view("/Views/fs/p1/showView.jsp"));
console.log(view("/Views/fs/p2/showView123.aspx"));
Open console

Try this
var msg = "/Views/GS/stockView.html";
var startIndex = -1;
var endIndex=-1;
var length = msg.length;
for (var i = length - 1; i >= 0; i--) {
if (msg[i] == '/'){
startIndex=i+1;
break;
}
if(msg[i]==".")
endIndex=i;
}
console.log(msg.substr(startIndex,endIndex-startIndex));
Or try this
var msg = "/Views/GS/stockView.html";
var split=msg.split("/");
split=split[split.length-1].split(".");
console.log(split[0]);

I have this simple problem, and I want a simple solution, if it exists.
Suppose I have the following string:
var myString = "IS is iS Is";
var myArray = [];
I want to get an array of size 4, where:
myArray[0] = 0;
myArray[1] = 3;
myArray[2] = 6;
myArray[3] = 9;

You can;
var myString = "IS is iS Is";
var myArray = [];
var re = /\b(is)\b/ig;
match = re.exec(myString);
while (match != null) {
myArray.push(match.index);
match = re.exec(myString);
}
document.write(myArray);

How do I split a string like this
"please help me "
so that I get an array like this:
["please ","help ","me "]
In other words,I get an array which preserves the space (or spaces)
Thanks

something like :
var str = "please help me ";
var split = str.split(/(\S+\s+)/).filter(function(n) {return n});
FIDDLE

this is tricky without using a function;
var temp = "", outputArray = [], text = "please help me ".split("");
for(i=0; i < text.length; i++) {
console.log(typeof text[i+1])
if(text[i] === " " && (text[i+1] !== " " || typeof text[i+1] === "undefined")) {
outputArray.push(temp+=text[i]);
temp="";
} else {
temp+=text[i];
}
}
console.log(outputArray);
I don't think a simple regex can help this out.
you can use prototype to use it like a native code...
String.prototype.splitPreserve = function(seperator) {
var temp = "",
outputArray = [],
text = this.split("");
for(i=0; i < text.length; i++) {
console.log(typeof text[i+1])
if(text[i] === seperator && (text[i+1] !== seperator || typeof text[i+1] === "undefined")) {
outputArray.push(temp+=text[i]);
temp="";
} else {
temp+=text[i];
}
}
return outputArray;
}
console.log("please help me ".splitPreserve(" "));
