But when i compile it with ng build --prod it's gives TypeError: $(...).multiple_emails is not a function , if it's not working correctly any other tool to convert from JavaScript to typescript ?
i had convert js into typesript using online compiler but nothing happened.

solved!!!!
finally i figure out the problem. it is in angular-cli.json.when i place my multiple_email.js after jquery-3.1.1.min.js,jquery.validate.min.js then it works like charm...!!! #rajesh thanks

Create a javascript object

I would say I am fairly decent with javascript and jQuery, well, enough to get the job done and done pretty well.
I do however lack a deep understanding of js.
I have created some functions for highlighting table elements.
ctrl+click toggles selections
shift+click+drag highlights selection
My question does not pertain to whether or not my implementation is the best way or not but ...
How do I abstract this functionality so I can add this functionality to any table. Like if I add more highlighting features and such and put this in its own .js file. How would I attach it to any html table?
Sorry if this has already been answered, but I could not think of what to search for.
Thank you.
****Newest Code****
This code is in its own .js file and is attached to my table.
All the current functionality is there. The only thing I am weary of is the .off() functions. In my case, I am reloading new tables.... as I type this, I realize I should just empty the tr's from the table instead of recreating a new table all the time, then I could get rid of the .off() calls.

you can wrap all this in a function since you have some local variables related to individual selection
$.fn.addEvents = function(obj) {
var properties = $.extend(true, {
shifting: false,
ctrling: false,
mousing: false,
mouseenter: 0,
mouseleave: 0,
trajectory: null
}, obj || {});
return $(this)
.off('click')
.off('contextmenu')
.on('click', function() {
.....
})
.on('mouseleave', function(e) {
//rename your local variables with `properties.` prefix
properties.mouseleave = e.clientY;
if (properties.shifting && properties.mousing) {
tmptrajectory = properties.mouseenter - properties.mouseleave < 0 ? 1 : -1;
}
if ($(this).hasClass('selected') && properties.shifting && properties.mousing && properties.trajectory != null && properties.trajectory != tmptrajectory) {
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
....
});
}
usage
$('#datatablebody tr').addEvents({ shifting: false, ctrling: true }); //custom settings
$('#someother tr').addEvents(); //default settings

you could add that functionality to a class and add that class to the tables you want to affect...
Here I create the class .myTableBeh and all tables with that class will have the behaviour you programmed.
var shifting = false;
var ctrling = false;
var mousing = false;
var mouseenter = 0;
var mouseleave = 0;
var trajectory = null;
$('.myTableBeh tr')
.off('click')
.off('contextmenu')
.on('click', function()
{
if(!ctrling)
{
$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
}
else if(ctrling && $(this).hasClass('selected'))
{
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
else if(ctrling && !$(this).hasClass('selected'))
{
$(this).addClass('selected');
$(this).find('td').addClass('selected');
}
})
.on('contextmenu', function(ev)
{
ev.preventDefault();
$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
showContextMenuTR($(this).closest('tr').attr('id'), ev.clientX, ev.clientY);
return false;
})
.off('mousedown')
.on('mousedown', function(e)
{
mousing = true;
multiselectrow($(this));
})
.off('mouseenter')
.on('mouseenter', function(e)
{
mouseenter = e.clientY;
multiselectrow($(this));
})
.off('mouseleave')
.on('mouseleave', function(e)
{
mouseleave = e.clientY;
if(shifting && mousing)
{
tmptrajectory = mouseenter - mouseleave < 0?1:-1;
}
if($(this).hasClass('selected') && shifting && mousing && trajectory != null && trajectory != tmptrajectory)
{
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
if(shifting && mousing && trajectory == null)
{
trajectory = tmptrajectory;
}
})
.off('mouseup')
.on('mouseup', function(e)
{
mousing = false;
trajectory = null;
multiselectrow($(this));

Thanks to the answer from #JAG I was able to create a nice add on to any HTML table that handles highlighting.
Check out the fiddle for the working version and please use it if you find it helpful or useful for your site.
You can even implement keys to move the tr position up or down in the table. I removed my implementation because it was specific to the project I am working on.
I made it so you have to mouse over the table in order to interact with it and mouse leave to un-focus it.
https://jsfiddle.net/kwj74kg0/2/
//Add the events simply by running this
$('#dtable tr').addEvents(0);
/**
* This add on can be applied and customized to any html tr set i.e. $('#tableid tr').addEvents()
* It will add highlighting capability to the table.
*
* Single click highlight tr
* Click -> Shift + click highlight/toggle range
* Shift+MouseDown+Drag highlight/toggle range
* Ctrl+Click toggle item

Autocomplete cities similar to kayak.com from Postgresql with PHP and JS

I would like to have a input where, when the user type in anything all the cities available appear to him. Something like the functionality in kayak.com
So if the user type in the letter M, all the cities starting with M will show like in the picture below.
So I have the following code that works but only for the options provided under var choices:
<form onsubmit="$('#hero-demo').blur();return false;" class="pure-form" style="border-top: 1px solid #eee;border-bottom:1px solid #eee;background:#fafafa;margin:30px 0;padding:20px 10px;text-align:center">
<input id="hero-demo" autofocus type="text" name="q" placeholder="Programming languages ..." style="width:100%;max-width:600px;outline:0">
</form>
<script src="https://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="jquery.auto-complete.js"></script>
<script>
$(function(){
$('#hero-demo').autoComplete({
minChars: 1,
source: function(term, suggest){
term = term.toLowerCase();
var choices = ['Birmingham', 'Dallas', 'Houston','New York', 'San Francisco'];
var suggestions = [];
for (i=0;i<choices.length;i++)
if (~choices[i].toLowerCase().indexOf(term)) suggestions.push(choices[i]);
suggest(suggestions);
}
});
});
</script>
Then I have this PHP code to pull all my cities from my postgresql database:
<?php
$db = pg_connect("$db_host $db_name $db_username $db_password");
$query = "SELECT * FROM cities";
$result = pg_query($query);
if (!$result) {
echo "Problem with query " . $query . "<br/>";
echo pg_last_error();
exit();
}
//This is just to print out all the cities I have in my database with their countries
while($myrow = pg_fetch_assoc($result)) {
$city = $myrow[city];
$country = $myrow[country];
echo $city;
echo $country;
echo '<br>';
}
?>
I have 2 questions:
How can I do to substitute the values in var choices for the values retrieve from my postgreqsl database with $query = "SELECT * FROM cities";?
How can I do to have also added the country so if there are two cities named the same in different countries or States all show up: Example:
If I type in Tole --> I'll see:
Toledo, Spain
Toledo, OH
Toledo, OR
Toledo, IA
Toledo, WA
Toledo, IL
Thank you so much

I really like this plugin called awesomeplete. Light, easy to use. It is very flexible with how you attach the options.

KeyPress doesn't return false in IE8

Im trying to prevent user to enter a space " " with KeyPress() using jQuery. it's work fine on all browser except IE8.
Here is my code:
$("<input type='text'>")
.attr( 'placeholder', opts.addTagPrompt )
.keypress( function(e) {
var $this = $(this),
pressed = e.which;
for ( i in opts.delimiters ) {
if (pressed == opts.delimiters[i]) {
if($this.val().indexOf(";",0) > 0)
{
var list = $this.val().split(';');
}else{
var list = $this.val().split(',');
}
for(var i in list){
self.add( list[i] );
}
e.preventDefault();
return false;
}
}
})
Update 1:
it's a plugin for tagify if user click space or Enter or Comma it's should return false and chance Css for the selected input.
(function ($) {
$.widget("ui.tagify", {
options: {
delimiters: [13, 32, 44], // what user can type to complete a tag in char codes: [enter], [space], [comma]
outputDelimiter: ',', // delimiter for tags in original input field
cssClass: 'tagify-container', // CSS class to style the tagify div and tags, see stylesheet
addTagPrompt: 'enter an email address' // placeholder text
},
_create: function() {
var self = this,
el = self.element,
opts = self.options;
this.tags = [];
var ctrlDown = false;
// hide text field and replace with a div that contains it's own input field for entering tags
this.tagInput = $("<input type='text'>")
.attr( 'placeholder', opts.addTagPrompt )
.keypress( function(e) {
var $this = $(this),
pressed = e.which;
for ( i in opts.delimiters ) {
if (pressed == opts.delimiters[i]) {
if($this.val().indexOf(";",0) > 0)
{
var list = $this.val().split(';');
}else{
var list = $this.val().split(',');
}
for(var i in list){
self.add( list[i] );
}
e.preventDefault();
return false;
}
}
})
// Ctrl+V Detection
.keydown(function(e)
{
if (e.keyCode == 17) ctrlDown = true;
})
.keyup(function(e)
{
if (e.keyCode == 17) ctrlDown = false;
})
.keyup(function(e)
{
var $this = $(this);
console.log($this.val());
if (ctrlDown && (e.keyCode == 86) ) {
if($this.val().indexOf(";",0) > 0)
{
var list = $this.val().split(';');
}else{
var list = $this.val().split(',');
}
var name_fix = "";
for(var i in list){
console.log(list[i]);
if(!checkEmail(list[i])){
name_fix = list[i]+", ";
}else{
if (name_fix != "") {
self.add( name_fix+list[i] );
name_fix = "";
}else{
self.add( list[i] );
}
}
}
e.preventDefault();
return false;
}
})
.keydown( function(e) {
var $this = $(this),
pressed = e.which;
// if backspace is hit with no input, remove the last tag
if (pressed == 8) { // backspace
if ( $this.val() == "" )
{
self.remove();
return false;
}
return;
}
});
this.tagDiv = $("<div></div>")
.addClass( opts.cssClass )
.click( function() {
$(this).children('input').focus();
})
.append( this.tagInput )
.insertAfter( el.hide() );
// if the field isn't empty, parse the field for tags, and prepopulate existing tags
var initVal = $.trim( el.val() );
if ( initVal ) {
var initTags = initVal.split( opts.outputDelimiter );
$.each( initTags, function(i, tag) {
self.add( tag );
});
}
},
Any one know how to fix that ?? thanks in advance.

Limit input to numbers and . on input field

Following on from another question I asked, i really didnt seem to be getting anywhere. Due to my ineptitude. I chose the guys answer because , well he answered my question.
I am gathering I didnt ask the right question cos I have no idea what to do ..
So issue is I have input element . Keeping it simple;
<input type="text" maxlength="12" name="price" id="price" class="foo">
I want users to be able to type in numbers only and only one period ( . ) anywhere in that price. so could be 3.00 or 300.00 or 3000
Could someone please help me out, I am going goggle eyed.
The Older question asked was here Quick regex with alert

You could, in the change event of the input, check if the number format is OK. This code will try to get the number and remove anything else: (I'm assuming you use jQuery, if not, please do)
$('#price').change(function() {
$(this).val($(this).val().match(/\d*\.?\d+/));
});
See it working here.
EDIT: if you don't have jQuery, this code does the same (at least in Chrome):
document.getElementById('price').onchange = function() {
this.value = this.value.match(/\d*\.?\d+/);
};
EDIT 2: not sure if I follow, but you could add this too to prevent letters and other characters before the change event:
$('#price').keypress(function(event) {
var code = (event.keyCode ? event.keyCode : event.which);
if (!(
(code >= 48 && code <= 57) //numbers
|| (code == 46) //period
)
|| (code == 46 && $(this).val().indexOf('.') != -1)
)
event.preventDefault();
});

Here is my solution(It also validates data/values copy&pasted):
function InputValidator(input, validationType, validChars) {
if (input === null || input.nodeType !== 1 || input.type !== 'text' && input.type !== 'number')
throw ('Please specify a valid input');
if (!(InputValidator.ValidationType.hasOwnProperty(validationType) || validationType))
throw 'Please specify a valid Validation type';
input.InputValidator = this;
input.InputValidator.ValidCodes = [];
input.InputValidator.ValidCodes.Add = function (item) {
this[this.length] = item;
};
input.InputValidator.ValidCodes.hasValue = function (value, target) {
var i;
for (i = 0; i < this.length; i++) {
if (typeof (target) === 'undefined') {
if (this[i] === value)
return true;
}
else {
if (this[i][target] === value)
return true;
}
}
return false;
};

To apply it to an input, do the following :
new InputValidator(document.getElementById('txtValidate'), InputValidator.ValidationType.Decimal);/* Numeric or Custom */
If you specify Custom as the validation type you have to specify the valid characters.
eg :
new InputValidator(document.getElementById('txtValidate'), InputValidator.ValidationType.Custom,'1234abc');

Cambraca aproach kind of works, but the best one is the last mentioned approach , you cancel the keypress event filtering the keys before it shows up instead of undoing what was already done. A consequence of changing the value after the fact is that it may affect the position of the caret in the field.
Here's an example of abstracting the idea in a cross-browser way. Somebody should port this to a jQuery plugin http://www.qodo.co.uk/assets/files/javascript-restrict-keyboard-character-input.html
Ok, I guess I'll port it. But I'm not a jQuery guy so this is an untested bare bones jQuery plugin that uses their code
http://jsfiddle.net/mendesjuan/VNSU7/3
(function( $ ) {
$.fn.restrict = function(regExp, additionalRestriction) {
function restrictCharacters(myfield, e, restrictionType) {
var code = e.which;
var character = String.fromCharCode(code);
// if they pressed esc... remove focus from field...
if (code==27) { this.blur(); return false; }
// ignore if they are press other keys
// strange because code: 39 is the down key AND ' key...
// and DEL also equals .
if (!e.originalEvent.ctrlKey && code!=9 && code!=8 && code!=36 && code!=37 && code!=38 && (code!=39 || (code==39 && character=="'")) && code!=40) {
if (character.match(restrictionType)) {
return additionalRestriction(myfield.value, character);
} else {
return false;
}
}
}
this.keypress(function(e){
if (!restrictCharacters(this, e, regExp)) {
e.preventDefault();
}
});
};
})( jQuery );
$('#field').restrict(/[0-9\.]/g, function (currentValue, newChar) {
return !(currentValue.indexOf('.') != -1 && newChar == ".");
});
