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 have an array and i want to insert "ZZ" if the current array value(string) contains "ata", the code should replace at the end of "ata" word.

var uniqueArray = duplicatesArray.filter(function(elem, pos) {
return duplicatesArray.indexOf(elem) == pos;
});
for (var i = 0; i < uniqueArray.length; i++) {
var st = uniqueArray[i];
if((st.endsWith("mak")==false) && (st.endsWith("mek")== false) && (st.length>3))
{
var b = "ata";
var insert = "ZZ";
var position = st.indexOf("b");
st = st.slice(0, position) + insert + st.slice(position);
document.writeln(st);
document.write("<br>");
}
}

I may need to edit this answer later once some details have been clarified, but it seems like you should use the .map() method on your uniqueArray.
This code will walk through each word in the list and either let it unchanged or apply the replacement if all conditions are fulfilled.
// using a shorter, already deduplicated list for sake of clarity
var uniqueArray = [
"abıca","gelmek","ata","atabeg","at","eri","yir","atalar","tutmak"
];
var result = uniqueArray.map(function(word) {
return (
!word.endsWith("mak") &&
!word.endsWith("mek") &&
word.length > 3 ?
word.replace(/ata/, "ataZZ") : word
);
});
console.log(result);

I am right or wrong? :)
var initialArray = ["abıca","abrık","apşak","abbak","abu","aparma","apalisına","appak","aparmadutı","apşak","apışık","apşak","apışıklık","apışık","apalak","apılamak","apul","apul","apulamak","aparmak","at","arkasına","gelmek","ata","atabeg","at","eri","at","ağaç","at","oğlanı","at","akdarıcı","at","otayıcı","at","uşağı","at","oğlanı","at","oynağı","at","bırakmak","at","boynuna","düşmek","at","boynuna","düşmek","at","cıvlandurmak","at","çapmak","at","çapmak","at","depretmek","at","depmek","atı","doldurmak","at","segirtmek","ateş","evi","ateş","göyniigi","atışmak","ateşe","urmak","ateşe","nal","komak","at","şalmak","at","şalmak","at","tonı","at","kaşnısı","at","kaldırmak","at","kulağı","at","koparmals","at","koşmak","at","kulağı","götliği","atlaz","atlandurmak","atlandurmak","atlanmak","atlu","azuğı","atımı","yir","ata","atalar","atıcıduğı","aç","itmek","acıtğan","acıtmak","aç","dirilmek","acır","acırak","acışıklık","acışmak","aç","tutmak"];

Code for Length of string to be displayed in front of actual string.
Example
length: 11, "This string"
Thank you.

var str = 'Hello World';
console.log('length: ' + str.length + ', "' + str + '"');
Evaluates to:
length: 11, "Hello World"

Solution :
var str = "This string";
var n = str.length;
var displaystring = 'length: '+ n + ', "' + str + '"'
//display the above string however you want.
//example below to show in a control name demo
document.getElementById("demo").innerHTML = displaystring;

I agree with #pointy that its not clear what you really need done but this might give you some idea
var str1 = "This string";
var str2 = str1.length;
var result = str2.concat(str1);

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);

Double clicking on an image in the #train div will delete that image and all the images to thr right of it.
var d should return the last image in the train div and var g should return the index of that image in the main_pics array.
$(document).ready(function () {
var main_pics = ["AN.gif", "BN.gif", "CN.gif", "DN.gif", "EN.gif", "GN.gif"];
var starting_pics = ["AN.gif", "CN.gif", "EN.gif"];
var i = 0;
for (i = 0; i < starting_pics.length; i++) {
$("<img/>").attr("src", "images/" + starting_pics[i]).appendTo("#main").addClass("pics");
}
// Code not relevant to the question.
$("#train").on("dblclick", ".pics", function () {
var l = $("#train").children(".pics").length;
var c = $(this).index();
$("#train").children().slice(c, l).remove();
var d = $("#train").children(".pics").last()
alert(d);
var g = $.inArray(d.src.split("/").pop(), main_pics);
alert(g);
});
});

Here is your fix:
var d = $("#train .pics").last();
var g = $.inArray(d.prop('src').split("/").pop(), main_pics);
