fail to validate user input in bootstrap modal by alert message - javascript

I'm able to validate user form in normal page without using modal, the alert is able to pop up if submit the form with empty text field.
Now I'm trying to make the form inside a modal and try to validate it but the validation does not show up and insert the blank data to database.
Here is the partial code.
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
<!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Upload </h4>
</div>
<div class="modal-body">
<form method="POST" >
<p>EventTitle :
<input type="text" name="eTitle" id="eTitle" placeholder="Say something about this image...">
</p>
<script type= "text/javascript">
$(document).ready(function(){
$('#createEvent').click(function(){
var event_Title = $('#eTitle').val();
if(event_Title =='')
{
alert("Title cannot be empty");
return false;
}
});
});
</script>
</div>
<div class="modal-footer">
<input type="submit" name="createEvent" id="createEvent" value="Insert" class="btn btn-info">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</form>
</div>

For one, you can use the built in HTML required attribute for validating empty input.
Ex: <input type="text" name="eTitle" id="eTitle" placeholder="Say something about this image..." required />
Otherwise you could try to use if (!event_Title.length > 0) {...}
One more advice, I recommend removing the javascript from inside the html code and put it on the bottom of the file or in an external file.
Hope this helps, feel free to reach out if this does not work.

How to trigger form submit from JavaScript after jQuery modal popup

Let's say I have the following form:
<form id="evidence-formset" action="{% url 'interpret-criteria' %}" method="post">
<div class="form-group row">
<!-- Some content here -->
<div class="col-auto">
<input type="submit" class="btn btn-primary" value="Calculate" />
<input type="reset" class="btn btn-secondary" value="Reset" />
<input type="submit" class="btn btn-dark" value="Register" onclick="validateRegister()" formaction='https://www.wikipedia.org/'/>
<input type="submit" class="btn btn-link" value="Export results as Excel" formaction="{% url 'export-interpretation' %}" />
</div>
</div>
<form>
And the following JS function (WIP):
function validateRegister() {
event.preventDefault();
$("#myModal").modal();
$("#registerSubmit").submit()
}
And this basic modal:
<div class="modal" id="myModal" tabindex="-1" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>Modal body text goes here.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary">Register changes</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
So basically what I want is that when I click the Register button a modal shows, asking for confirmation. If I click again on 'Register' then the input will submit and the webpage should redirect to wikipedia (this is just an example). If I click Close, no form should be submitted and the modal will disappear.
I checked all the previous StackOverflow questions and I couldn't find an answer that worked for me. The closest solution I found is this but it doesn't work.
UPDATE WITH A SOLUTION:
function validateRegister() {
event.preventDefault();
$("#myModal").modal();
$("#myModal").on("click",".btn-primary", function(){
$('#evidence-formset').attr('action', 'https://www.wikipedia.org/').submit();
});
}
remove onclick and add this
$("#evidence-formset").on("submit",function(e) {
e.preventDefault();
$("#myModal").modal();
})
Add ok/cancel to the buttons of the modal
$("#myModal").on("click",".btn-primary", function(){
$("#evidence-formset").submit(); // you can add if (validate(....) in front if you have any validation
});
$("#myModal").on("click",".btn-secondary", function(){
$("#myModal").modal('toggle');
});

Submitting form data from modal, modal won't close

I'm creating a type of content management system that allows users to create pages based on templates.
I have a page that has 2 placeholder divs. Below is an example of one. When you click on the div, a modal pops up that allows the user to use TinyMCE to create content. The idea is to set the content, hit the "Get Data" button and have the modal disappear with the content from the editor now displaying inside the original div.
This is working as far as p utting the content in the div when I hit submit. The body of the modal disappears at this point, but the gray opacity screen that usually sits under the bootstrap modal is still present and I can't any longer do anything on the page. I'm wondering what I'm doing wrong here and how I can fix it to fully close the modal when I hit the submit button.
<div class="leftContent">
<div class="modal fade bd-example-modal-lg" id="leftFiftyModal" tabindex="-1" role="dialog" aria-labelledby="leftFiftyLabel" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="leftFiftyModal">Content Library:</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<h3>Create your own content</h3>
<form id="form-data" method="post">
<textarea id="mytextarea"></textarea>
<input type="submit" value="Get Data">
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</div>
<script type="text/javascript">
$(document).ready(function(){
$("#form-data").submit(function(e){
var content = tinymce.get("mytextarea").getContent();
$(".leftContent").html(content);
return false;
});
jQuery.noConflict();
$('#leftFiftyModal').modal('hide');
});
</script>
Try:
<script type="text/javascript">
$(document).ready(function(){
$("#form-data").submit(function(e){
var content = tinymce.get("mytextarea").getContent();
$(".leftContent").html(content);
jQuery.noConflict();
$('#leftFiftyModal').modal('hide');
return false;
});
});
</script>

Issue in passing a data id to bootstrap modal

I have a listing page containing a link button to show modal repeating in a PHP loop. I have searched and found these:
Passing data to a bootstrap modal, Passing data to Bootstrap 3 Modal and Pass id to Bootstrap modal and some others but failed.
What I want
I have fetched the data id from database and pass it to bootstrap modal and there I will use this id to display more info through MySQL queries.
I have written all the code but the ID is not passing to the modal.
Modal Link Button code
<a class="btn btn-warning btn-minier" href="#modal-form-show" role="button" data-toggle="modal" data-target="#myModal" data-id="<?php echo $cottage_id ?>"><i class="icon-edit bigger-120"></i> Reservation </a>
Modal code
<!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Reservation Details</h4><br>
<h5>Cottage Id :</h5>
<h5>Cottage Title :</h5>
</div>
<div class="modal-body">
<p>ID WILL SHOW IN THIS TEXT FIELD.
<input type="text" name="cottage" placeholder="cottage id" value="" id="cottage" />
</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
JS code
$('#modal-form-show').on('show.bs.modal', function(e) {
var c_id= $('a[href="#modal-form-show"]').data('id');
//var c_id= $(this).data(id) - checked both
$("#cottage").val(c_id);
});
I have taken a text input in modal named cottage and I want show that id in this input.
Try this snippet:
$('.btn-minier').click(function(){
var c_id = $(this).attr('data-id');
$('#cottage').val(c_id);
});
I have change little , when button click show the popup & i've set the value of data-id=2
Button
<a class="btn btn-warning btn-minier" id="btnModalPopup" href="" role="button" data-toggle="modal" data-target="" data-id="2"><i class="icon-edit bigger-120"></i> Reservation </a>
I add button in you modal
<div id="myModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Reservation Details</h4><br>
<h5>Cottage Id :</h5>
<h5>Cottage Title :</h5>
</div>
<div class="modal-body">
<p>
ID WILL SHOW IN THIS TEXT FIELD.
<input type="text" name="cottage" placeholder="cottage id" value="" id="cottage" readonly />
</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-success" data-dismiss="modal" id="btnSubmit">Submit</button>
</div>
</div>
</div>
</div>
Javascript code
<script>
$(document).ready(function () {
$('#btnModalPopup').click(function () {
var c_id = $(this).data('id');
console.log(c_id)
$('#myModal #cottage').val(c_id)
$('#myModal').modal('show')
});
$('#btnSubmit').click(function () {
alert('submit button click')
// get the id , from input field.
var id = document.getElementById('cottage').value;
console.log(id)
alert(id)
//You can set the id - to php variable - then hit to sever by ajax
})
});
</script>
Try using attr method of JQuery
$('#modal-form-show').on('show.bs.modal', function(e) {
// instead of this
//var c_id= $('a[href="#modal-form-show"]').data('id');
// try this one
var c_id= $('a[href="#modal-form-show"]').attr('data-id');
//var c_id= $(this).data(id) - checked both
$("#cottage").val(c_id);
});

How Can I use the textbox value as a where clause in php

I have been doing this some time now. I have an anchor tag that opens a pop up modal and passes the dropdown value to that modal which I already accomplished.
Now In my modal, I need to use the value on the textbox which is hidden (but not for now) to a mysql query.
I'm thinking on how Can i put that value in textbox to a php variable.
Need help please.
Here's my javascript for the opening of modal.
<script type="text/javascript">
$('#modalRegister').on('show.bs.modal', function(e) {
var modal = $(this),
datestart = $('#datestart').val();
modal.find('#myVal').val(datestart);
})
</script>
Now my Modal
<div id="modalRegister" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title" style="text-align-last: center">Register</h4>
</div>
<div class="modal-body">
<input type="text" id="myVal" value=""/>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
Im thinking of doing a query there to cast a table and put the results on that table. The where clause if <input type="text" id="myVal" value=""/>

How do I open a modal onclick?

I want to open a modal when my input type "Verwijderen" is pressed. But it doesn't show up? What am I doing wrong? Even W3schools examples don't work in Fiddle for example. I am missing something I guess but what?
<td colspan="2">
<input type="submit" style="width:140px;" value="Opslaan"/>
<input
type="submit"
style="width:140px;"
id="cancelForm"
class="ketchUp-default"
value="Annuleren"/>
<input
type="submit"
id="deleteEvent"
value="Verwijderen"
style="width:140px;"
class="ketchUp-default"
data-toggle="modal"
data-target="confirm-delete"/>
<div
class="modal fade"
id="confirm-delete"
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">Confirm Delete</h4>
</div>
<div class="modal-body">
<p>You are about to delete one track, this procedure is irreversible.</p>
<p>Do you want to proceed?</p>
<p class="debug-url"></p>
</div>
<div class="modal-footer">
<button type="button" class="btn" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-danger btn-ok">Delete</button>
</div>
</div>
</div>
</div>
Are you using BootStrap 3? I think your mistake is that you are not using the "#" ID selector in your data-target on your input. Change your input code to this:
<input
type="submit"
id="deleteEvent"
value="Verwijderen"
style="width:140px;"
class="ketchUp-default"
data-toggle="modal"
data-target="#confirm-delete"/>
Here is a working plunk.
Your input is a submit, so your page is submitting the form, and the modal does not have time to be shown.
Try to convert your submit button to a simple button (not submit), and your modal will be shown.
<input
type="button"
id="deleteEvent"
value="Verwijderen"
style="width:140px;"
class="ketchUp-default"
data-toggle="modal"
data-target="confirm-delete"/>
