javascript error with my code

javascript error with my code - javascript

I'm trying to build a sophisticated automatic form filler. I wrote the code below, but when I'm trying to run it in FireBug, it keeps saying syntax error.
In this code I am attempting to create a pop up form in the page I am filling, create usernames as demands (function a()). In function Nickname(), I'm getting the users I created in function a(), save it in array, pick a username randomly, fill it out in the appropriate place, and check if it's okay or not. Function pass and checked is filling the rest of the form.
var f = document.createElement("form");
var i = document.createElement("input");
i.type = "text";
i.name = "username";
i.id = "username";
var ien = document.createElement("input");
ien.type = "number";
ien.name = "quantitye";
ien.id = "quantity";
var b = document.createElement("button");
b.onclick = "a()";
var bu = document.createElement("button");
bu.onclick = "bu()";
f.appendChild(i);
f.appendChild(ien);
f.appendChild(b);
f.appendChild(bu);
document.getElementsByTagName('body')[0].appendChild(f);
function a() {
var text = document.getElementById("username").value ;
var i;
var j ;
j = document.getElementById("quantity").value;
var text1 = "";
for(i = 1; i < j ; i++) {
text1+= text + i + " " ;
}
document.write(text1);
}
function Nickname() {
var array =[];
var Guser;
Guser = a();
array = Guser.split(',');
var length = array.length;
var randome = array[math.floor(math.random() * array.length)];
var index = array.indexOf(randome);
document.getElementById("nick").value = randome;
var r = confirm("Is It Okay To Continue ?");
if ( r == true ) {
if(index>-1 && length > -1) {
array.splice(index,1);
}
else if( r != true ) {
randome = array[math.floor(math.random() * array.length)];
document.getElementById("nick").value = randome;
var s = confirm("Is It Okay To Continue ?");
while ( s != true ) {
randome = array[math.floor(math.random() * array.length)];
document.getElementById("nick").value = randome;
}
}
}
}
function pass() {
var password = "123456789m";
document.getElementById("password").value = password;
document.getElementById("pass_conf").value = password;
}
function checked() {
var checked = true ;
document.getElementById(agd).checked = true ;
}

This declaration doesn't look correct:
function all() {
function Nickname() {
Did you really intend to declare Nickname() inside all()?

Trouble with calling prompts twice

I am having trouble with running a prompt twice. I do not know how to link the let statement at the bottom of the statement with var options = passwordOptions(); without running through the prompts twice.
function generatePassword() {
var options = passwordOptions();
var result = []
var possible = []
var guaranteed = []
var password = ""
if(options.specialCharacters){
possible = possible.concat(specChar)
guaranteed.push(getRandom(specChar))
password+= getRandom(specChar)
}
if(options.lowerCaseChar){
possible = possible.concat(lowerCase)
guaranteed.push(getRandom(lowerCase))
password+= getRandom(lowerCase)
}
if(options.upperCaseChar){
possible = possible.concat(upperCase)
guaranteed.push(getRandom(upperCase))
password+= getRandom(upperCase)
}
if(options.numChar){
possible = possible.concat(numbers)
guaranteed.push(getRandom(numbers))
password+= getRandom(upperCase)
}
let passwordLength = passwordOptions().passwordLength
while(password.length < passwordLength) {
password+=guaranteed[Math.floor(Math.random() * guaranteed.length)]
}
return password;
}
function getRandom(arr) {
var randomIndex = Math.floor(Math.random() * arr.length)
var randomElement = arr[randomIndex]
return randomElement;
}

It always show either one output, either it highlight the keywords or only the alert box,how to achieve both at the same time

//grab all div elements in the pages;
let elt = document.getElementsByTagName("div");
var i;
var b = [];
b[0] = "password";
b[1] = "update";
b[2] = "account";
b[3] = "blocked";
b[4] = "alert";
b[5] = "confirm";
b[6] = "cash";
b[7] = "extra";
b[8] = "subscribe";
b[9] = "sample";
b[10] = "winner";
b[11] = "offer";
b[12] = "promotion";
b[13] = "urgent";
b[14] = "action";
b[15] = "update";
b[16] = "luxury";
b[17] = "limited";
b[18] = "login";
b[19] = "alert";
b[20] = "income";
b[21] = "bonus";
b[22] = "verify";
b[23] = "banking";
b[24] = "lowest";
b[25] = "deal";
b[26] = "unusual log in activity";
function scanDOM() {
//loop for html elements;
for (i = 0; i < elt.length; i++) {
var singleDiv = elt[i];
//loop for keywords;
for (j = 0; j < b.length; j++) {
var str = singleDiv.innerHTML;
if (str.indexOf(b[j]) > -1) {
//if found that the keywords match with the one in array, it will highlight the words;
str = str.replace(b[j], '<span style="background-color:#f6ff00;">' + b[j] + '</span>');
singleDiv.innerHTML = str;
popup();
}
}
}
}
// scan through the pages every 5 seconds;
setInterval(scanDOM, 5000);
//alert message;
function popup() {
alert * ("**WARNING!**");*
}

Array doesent update values

I want my array to be updated as soon as I run the replace function. What actually happens is that all the elements of my array get deleted here is the code:
var Person = [];
var editPersonId = 0;
var Details = [];
function AddPerson() {
this.Details[0] = document.getElementById("fname").value;
this.Details[1] = document.getElementById("lname").value;
this.Details[2] = document.getElementById("age").value;
this.Details[3] = document.getElementById("mobil").value;
this.Details[4] = document.getElementById("adress").value;
Person.push(this.Details);
}
function Clear(){
document.getElementById("fname").value = "";
document.getElementById("lname").value = "";
document.getElementById("age").value ="";
document.getElementById("mobil").value = "";
document.getElementById("adress").value = "";
}
function ShowContacts(){
var testIt= document.getElementById("search").value;
var i=0, k=0, indx=[], msg;
for ( i=0; i < Person.length; i++)
{
for ( k=0; k<=4; k++)
{
if (Person[i][k] === testIt)
{
document.getElementById("newFname").value = Person[i][0];
document.getElementById("newLname").value = Person[i][1];
document.getElementById("newAge").value = Person[i][2];
document.getElementById("newMobil").value = Person[i][3];
document.getElementById("newAdress").value = Person[i][4];
console.log(1);
editPersonId = i;
break;
}
}
}
}
function Replace(){
Person[editPersonId][0] = document.getElementById("newFname").value;
Person[editPersonId][1] = document.getElementById("newLname").value;
Person[editPersonId][2] = document.getElementById("newAge").value;
Person[editPersonId][3] = document.getElementById("newMobil").value;
Person[editPersonId][4] = document.getElementById("newAdress").value;
}
function Run(){
this.AddPerson();
this.Clear();
}

You override the contents of your Person insde of replace().
Person[editPersonId][0] = ...
While editPersonId is 0, means that the item you inserted in AddPerson will be overriden. And before replace(), you run clear(), which empties your inputs. So the elements don't get 'deleted', you replace them with an empty string.

Javascript generating random password not working

Just trying to make a random password generator and I'm not getting any output in my alert I'm using to test. Not getting any errors so I'm not sure what my mistake is.
"use strict";
var $ = function(id) { return document.getElementById(id); };
var getRandomNumber = function() {
var num = parseInt$("num").value = "";
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
for (var i = 0; i < num.length; i++)
text += possible.charAt(Math.floor(Math.random() * possible.length));
return text;
}
alert(text).toString());
};
var clearFields = function() {
$("num").value = "";
$("password").value = "";
$("num").focus();
};
window.onload = function() {
$("generate").onclick = getRandomNumber;
$("clear").onclick = clearFields;
$("num").focus();
};

You do have an error.
There is an extra ) in this statement alert(text).toString());.

Codeigniter Auto completion is not working

Hello Auto completion is not working well in my application.When we type a name it displays only a blank list[ Screenshots attached ].
Controller Code
public function list_UserByName($letters)
{
if(strpos($letters, ","))
{
$letters1 = explode(",",$letters);
$lecount = count($letters1);
$letters = $letters1[$lecount-1];
}
$letters = preg_replace("/[^a-z0-9 ]/si","",$letters);
$response=$this->user_model->getAutoUserList($letters);
}
Model Code
public function getAutoUserList($letters)
{
$letters = preg_replace("/[^a-z0-9 ]/si","",$letters);
//AND user_type='C' AND user_status='A'
$query="select * from gm_users where uname Like '%$letters%'";
$result_query =$this->db->query($query);
foreach($result_query->result() as $result)
{
//echo "###".$result."|";
//$pinlevel =$this->functions->get_pinlevel($result->pinLevel);
//echo $result->userId."###".$result->uname." [ ".$pinlevel." ] "."|";

Am a beginner in php as well as Codeigniter

Just echo your data in your controller
change
$response=$this->user_model->getAutoUserList($letters);
To
echo $this->user_model->getAutoUserList($letters);

change
onkeyup="ajax_showOptions(this,'getCountriesByLetters',event);
to
onkeyup="ajax_showOptions(this,'list_UserByName',event);
there is a question on this topic on stackoverflow, but an entire different process.
