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 duplicatesArray = ["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"
];
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);

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);

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(" "));
