How to close & open a modal like Bootstrap

I want to create a modal like Bootstrap ...
I have wrote this codes :
<button type="button" data-target="#myModal" class="btn btn-primary">Open Modal</button>
<div class="modal fadeIn" id="myModal">
<div class="modal-header">
Roj Framework <span class="close-btn">×</span>
</div>
<div class="modal-content">
Hi, This Roj Framework !
</div>
<div class="modal-footer">
Continue ...
</div>
</div>
But I have a problem in understanding how to close & open it. I put a data-target for button to match with Modal Box ID & I don't display the modal from the beginning ..., So I wrote this code but It doesn't work ...
$('.modal').css('display', 'none');
$('button').click(function(){
var boxID = $(this).data('target');
var modalBox = $('.modal');
var modalBoxAttr = modalBox.attr('id');
if('boxID' == 'modalBoxAttr') {
modalBox.css('display', 'block');
}
});

There a few mistakes with your code.
Mistake 1:
Here:
if('boxID' == 'modalBoxAttr')
You are currently checking the strings and not the objects. What you have written is the following:
If the string "boxId" is equal to the string "modalBoxAttr" do something. And both strings are not the same, so you get a false result.
Mistake 2:
You are complicating the code too much.
You can just simplify it like this.
$('button').click(function(){
var boxID = $(this).data('target');
var boxObject = $(boxID);
if(boxObject.length) {
boxObject.toggle();
}
});
.modal { display: none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button type="button" data-target="#myModal" class="btn btn-primary">Open Modal</button>
<div class="modal fadeIn" id="myModal">
<div class="modal-header">
Roj Framework <span class="close-btn">×</span>
</div>
<div class="modal-content">
Hi, This Roj Framework !
</div>
<div class="modal-footer">
Continue ...
</div>
</div>
Use more often console.log() to debug your code and check if you are actually entering a specific section and if your logic is correct.

Try following approach.
Remove data-target="#myModal" from button
<button type="button" class="btn btn-primary">Open Modal</button>
Button click:
$('button').click(function(){
$("#myModal").modal('show');
}});

how can i create a modal by remote and initial textbox in the same function using jquery?

script.js
function change_val(){
$("#remoteModal2").modal({
remote:"modals/edit_text_value.html",
show:true
});
$("#my_textbox").val("this is a text")
}
index.html
<div class="modal fade" id="remoteModal2" tabindex="-1" role="dialog" aria-labelledby="remoteModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
</div>
</div>
</div>
<button onclick="change_val()" >show modal</button>
edit_text_value.html
<div class="modal-header">
header
</div>
<div class="modal-body">
<textarea id="my_textbox"></textarea>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">cancel</button>
</div>
The problem is that I must run it twice to make it work !
How to do all the operations in a function ?

shown.bs.modal OR show.bs.modal
When we use this code :
.on('shown.bs.modal')
.
$('#remoteModal2').on('shown.bs.modal', function (e) {
$("#my_textbox").val("this is a new text);
return e.preventDefault();
});
import modal (remote "edit_text_value.html")
Open modal
After the completion of loading and effects , change value..
show new value...
But this code :
.on('show.bs.modal')
Apply the changes ,Before reading the tags and remote the modal...
Therefore, it is not effective.
Because it can not find this ID (#my_textbox) Before remote modal page!

How to pass and get modal value

First, my bootstrap modal is like this:
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<-- modal
header -->
<div class="modal-body">
<form class="form-horizontal" id="composeForm" method="POST" action="composeMessage">
<div class="form-group">
<label class="col-sm-2 control-label">To</label>
<div class="col-sm-8">
<input type="text" class="form-control" id="sendToId" name="requestId">
</div>
</div>
<div class="line line-dashed b-b line-lg pull-in"></div>
<div class="form-group">
<label class="col-sm-2 control-label">Message</label>
<div class="col-sm-8">
<div class="btn-toolbar m-b-sm btn-editor"
data-role="editor-toolbar" data-target="#editor"></div>
<div id="editor" class="form-control" style="overflow:scroll;
height:150px;max-height:150px" contenteditable="true"></div>
<textarea style="display:none" id="divText" name="message"></textarea>
</div>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" id="sendSave" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
and my Javascript so far is like this:
$(function(){
var message;
$("#myModal").on('show.bs.modal', function(event){
var atag = $(event.relatedTarget); //I'm using a tag to open modal
var userNick = atag.data("nick");
var userComp = atag.data("comp");
var modal = $(this);
/*
skipped all dynamically setting values & changing attributes of tags
*/
document.getElementById("divText").value = document.getElementById("editor").innerHTML;
message = document.getElementById("divText").value;
});
$("button.btn.btn-primary").on('click', function(){
alert(message);
});
});
First, I have foreach loop in the same JSP, and the anchor tag opening the modal is in it. So I have multiple anchor tags.
The anchor tag opening modal is like this:
<a href="#myModal" data-target="#myModal" data-toggle="modal"
data-nick="${f.recomUserNick}" data-comp="${f.compatibility}">
I managed to set values and change attributes dynamically, and now I'm trying to send data from modal to controller (Spring MVC).
However, I have problem getting the 'message'. In the modal, the client writes something, and I first want to get the string value of that and check on alert to see if I can later send it to controller. What happens is that when I first open the modal, write something in it, and click the button (in the modal-footer, with id="sendSave"), I can't get the message. I close the modal, open it again -- in the message area it has what I wrote. I click the button, then I see my message in the alert window.
First, when I reopen the modal, I don't want to see what I wrote before, and I want to get the string value the first time, without having to open the modal again. I don't have a problem getting the string value, so I thought the problem was about where I put the codes, so I shifted my codes around for hours with no success. Can you please tell me how I should fix my codes? Thanks in advance.

You set the 'message' var in $("#myModal").on('show.bs.modal'.
At that point (in the first show) the message hasn't been typed yet.
If you move that code to the clickhandler, it takes the message after you have typed it:
$("button.btn.btn-primary").on('click', function() {
document.getElementById("divText").value = document.getElementById("editor").innerHTML;
message = document.getElementById("divText").value;
alert(message);
});

Getting the id of the anchor tag which was clicked

This is a list representation of data which is coming from a php database.The list is fetched using a foreach php loop and the data inside the achor tag is populated accordingly.
<?php foreach($array as $iterate):?>
<div class="col-sm-3">
<div class="panel panel-default">
**<a onClick='theFunction();' id="hello" href="#myModal" style="text-decoration:none;">**
<div class="panel-heading">
<img src ="audi_sillhouete.jpg" style="height:100%; width:100%;">
<p id="10" style="position:absolute; top:10%; padding-left:5%; padding-right:15%;"><?php echo $iterate->test_name ?></p>
</div>
</a>
</div>
</div>
<?php endforeach;?>
As you can see here, inside the anchor tag i have href-ed it to a modal box which will show a message whenever the user clicks on any of the link. There is a button in the modal window which will take the user to a different page.
The issue is that i want to pass certain value along with the url, but cannot do so as the link to the next page is defined in the modal window specification part.
So i came up with this solution. I thought of using the id attribute of the anchor tag, I tried to get the id attribute of the anchor which was clicked using javascript.
<script type="text/javascript">
function theFunction()
{
var id = $('a', this).attr('id');
alert(id);
}</script>
From this i wanted to initialize a php variable and then use that php variable to pass as value in the href of the modal window button. But the value i am getting in the alert box is 'undefined' for some reason. I have tried all possible combinations of this.
$('a',this).attr('id');
$this.id;
Everything return 'undefined'.
Reference-This is the code for the modal window part.
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Instructions</h4>
</div>
<div class="modal-body">
Your test is about to commence. A timer will be initiated after the moment you start the test. You may choose to answer a question, or leave it empty. You can also attempt the questions in any order that you find suitable.<br><br>Upon completion of the test, click on "Submit" to see your performance statistics.<br><br><br>Good luck!
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Continue</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->

Please try this
$(document).on('click', 'a', function () {
alert(this.id);
});
DEMO

You can use other attribute in anchor like :
<a href='' id='hello' para-id='somevalue'></a>
alert($("#hello").attr("para-id"));

The below jQuery function runs through all the a tags on page load and adds id to the end of the link.
$(function(){
$('a').each(function(){
var id = $(this).attr('id');
var url = $(this).attr('href') + '?id=' + id;
$(this).attr('href',url);
});
});

Select box initialized after not working properly

I'm trying to get the value of a select box but it always bring me the first value.
At the begin the select is empty. I press a button that shows the modal and loads the info of the select box. I think the problem comes 'cause I'm not loading the select options until the button is pressed because I tried with another select and it worked well
this is the modal:
<div class="modal fade" id="myModalPremios" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">Premios</h4>
</div>
<div id="premios" class="modal-body">
<jsp:include page="../frag/premios-list-frag.jsp"/>
</div>
<div class="modal-footer">
<button class="btn btn-danger" aria-hidden="true" data-dismiss="modal">Ok</button>
</div>
</div>
</div>
</div>
this is the form inside the modal:
<form class="form-horizontal" role="form">
<div class="form-group">
<input type="hidden" id="id" name="quiniela.id" value="${quiniela.id }"/>
</div>
<div class="form-group">
<label for="plantillaOwnerQuiniela" class="col-sm-4 control-label">Quiniela</label>
<div class="col-sm-5">
<select class="form-control" name="quiniela.plantillaOwnerQuiniela" id="plantillaOwnerQuiniela" ${read }>
<c:forEach items="${lista2 }" var="pl">
<option value="${pl.id }"
<c:if test="${pl.id == quiniela.plantillaOwnerQuiniela.id}">selected="selected"</c:if>>${pl.nombrePlantillaOwner} - ${pl.precioQuiniela}Bs</option>
</c:forEach>
</select>
</div>
</div>
</form>
this is how i show the modal:
$("#myModal").modal("show");
I've read that maybe the element is not present in the Dom, then I've tried using this function to see if something happen but It doesn't work.
$('#plantillaOwnerQuiniela').on('change',function() {
var selectVal = $('#plantillaOwnerQuiniela :selected').val();
alert(selectVal);
});

Just a guess, but it seems like the plantillaOwnerQuiniela element is not present in the DOM at the time you are binding your change listener.
Try the following:
$("body").on("change", "#plantillaOwnerQuiniela", function(e){
var selectVal = $(e.currentTarget).val();
alert(selectVal);
});
Use .on() to attach the listener to body and delegate it to the select, vs. attaching to the select itself; which may or may not be present on pageload.

You should bind the change event to the popover initialize method like this:
$('.button').popover({
html : true,
content: function() {
return $('#popover_content_wrapper').html();
}
}).parent().delegate('#plantillaOwnerQuiniela', 'change', function() {
alert($(this).val());
});
Here is the example !

I fixed my own problem by including the modal-body class when trying to read the value of if. Like this:
$('.modal-body #plantillaOwnerQuiniela :selected').val();
