Send value from one button to another button express-handlebars? - node.js

I am showing some dynamic value on a table. in the table each row have a delete button( Suppose Button A ). If click the delete button ( Button A ) open a modal to confirm delete and there have confirm button( Button B ). From confirm button I am calling the api to delete the entity with the entity id.
Now I have the id on Button A and I am sending the request from button B. How can I sent the id from Button A to Button B.
Button A:
<td>
<button data-toggle="modal" value = {{this.id}} data-target="#myModal">
<i class="fa fa-trash-o" aria-hidden="true"></i>
</button>
</td>
Modal With button B:
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Confirm Delete</h4>
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-header">
Are you sure you want to delete the entry?
</div>
<div class="modal-footer">
yes
</div>
</div>
</div>
</div>
I have given the {{this.id}} on the url of button B but it is always deleting the top or last element ?

add a class (example .delete) to the button,
<button data-toggle="modal" value ={{this.id}} class="delete" data-target="#myModal">
<i class="fa fa-trash-o" aria-hidden="true">delete</i>
</button>
then add a class to the confirmation link (example .yes):
yes
then get onclick event on the button and get the value of the button and insert it in the href attribut :
$(document).on("click", ".delete", function () {
var value = $(this).val();
console.log("value : ", $(this).val())
$(".modal-dialog .yes").attr("href","/admin/dashbord/category/"+value+"/delete");
});

EJS just outputs the first found user in some cases

I'm Using mongoDB and ejs to display all my users in a table. The table also has some action buttons to delete the user and to change the users role. The buttons open a popup to change the role or to confirm the deletion. But EJS doesn't pass the users info into the popup. It works totally fine in the table, but not in the popup.
My EJS User Table with the Role change Popup:
<tbody>
<%users.forEach(function(users){%>
<tr>
<td><%=users.name%></td>
<td><%=users.username%></td>
<td><%=users.createdAt%></td>
<td><span class="badge label-table badge-<%=users.role%>"><%=users.role%></span></td>
<td><span class="badge label-table badge-<%=users.verifyEmailToken%>"><%=users.verifyEmailToken%></span></td>
<td>
<button type="submit" class="btn btn-xs btn-success" data-toggle="modal" data-target="#con-close-modal" name="changeRoleButton"><i class="remixicon-user-settings-line"></i></button>
</td>
</tr>
<div id="con-close-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" style="display: none;">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Change <%=users.name%> Role</h4>
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
</div>
<form class="" action="/changeuserrole" method="post">
<div class="modal-body p-4">
<div class="row">
<div class="col-md-12">
<div class="form-group">
<label for="field-1" class="control-label">User Role</label>
<select class="form-control" name="role">
<option>Partner</option>
<option>Admin</option>
<option>User</option>
</select>
</div>
<button type="submit" value="<%=users._id%>" name="userroleid" class="btn btn-primary">Submit</button>
</div>
</div>
</div>
</form>
</div>
</div>
</div>
<%});%>
</tbody>
Here is my app.js where I search for the users and pass them to EJS:
app.get("/users", function(req, res) {
if (req.isAuthenticated() && req.user.role === "Admin") {
User.find({}, function(err, foundUsers) {
if (err) {
console.log(err);
} else {
res.render("users", {
users: foundUsers,
name: req.user.name.replace(/ .*/, ''),
email: req.user.username,
});
}
});
} else {
res.redirect("/login");
}
});
All the <%=users...%> tags work inside the table, but not inside the popup divs. Inside the Popup it just displays the information from the first user in the Database, which is super strange.
I would be very thankful for any kind of help. Thanks!
Your ejs code is good. I think that the problem is the id of each modal.
For each user you generate a modal with id="con-close-modal", So all your modals have the same id. As a result, every submit button (all of them have the same data-target="#con-close-modal"), triggers the same modal, probably the first one.
I recommend you, give each modal a unique id like
<div id="<%= users._id %>" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" style="display: none;">
and give each submit button the right data-target attribute
<button type="submit" ... data-target="#<%= users._id %>"...></button>
I may be wrong, but since the popup is displaying only the info from the first user, you may need the specific user id to be apart of the link. I had a similar issue with a project, except it was a link to a new view instead of a pop up.
I hope this documentation may be of some help

Pass Dynamic Table Row Data to Modal Dialog via Delete Button

Issue
There is a delete button on each row of data that opens a Bootstrap modal confirming that the user wants to indeed delete that row's data. Upon a submit in the modal, this will initiate a DELETE request in the form of a form element.
I want to pass the selected row's associated account._id variable so that I can modify the form's action attribute to /<%= account._id %>/?_METHOD=DELETE.
I am having trouble accessing the modal's parent window DOM elements.
My jQuery code is as follows:
<script>
$(document).ready(function () {
console.log("loaded and ready to go!"); // works as expected
var $remove = $(".remove"); // works as expected
console.log($remove.length); // works as expected
$(".remove").click(() => {
console.log("I'm in the modal!") // works as expected
var $parent = $(this).parent().closest("tr"); // find row
console.log($parent); // w.fn.init [prevObject: w.fn.init(0)]
var $account_id = $parent.find("th"); // find account id
console.log($account_id); // w.fn.init [prevObject: w.fn.init(0)]
console.log($account_id.text()); // returns blank type string
$("#remove-form").prop("action", "/" + $account_id + "?
_method=DELETE"); // change action attribute to account id value
})
});
</script>
Methods tried:
console.log(window.parent.$(this).closest("tr"));
// returns w.fn.init [prevObject: w.fn.init(1)]
you have placed the modal inside the forEach loop. So you dont have only one modal, instead you have one for each row. The problem here is that you assigned the same id removeAccountModal for all of them. Try to assign a unique id for each modal, for example:
<div class="modal fade" id="<%= account._id %>" tabindex="-1" role="dialog" aria-labelledby="removeAccountModalLabel" aria-hidden="true">
and on each delete button replace data-target with
data-target="#<%= account._id %>"
So you have unique modals and now you can place <%= account._id %> directly in action attribute
Thank you #dimitris tseggenes for pointing me in the right direction.
The unique ids for each modal div was imperative here. It turns out the id attribute value must not solely consist of numbers.
I refactored the id and target-data attributes to look like the following, respectively:
id="account<%= account._id %>id"
data-target=#account"<%= account._id %>id"
I have learned the following from the responses in this post:
Don't forget to make modal divs unique if you will have multiple modals, i.e. in a table and to alter the action element respectively using the data-target attribute
id attributes must not solely contain numbers

Pass Data from MongoDB to Bootstrap Modal Using EJS

I'm building an express app which comprises ejs and bootstrap for rendering views, node and express for server side and mongodb for storage.
I have a form (contained in a modal) in which I can post data. After submitting the form, the values are saved to mongodb.
Here's the snippet for edit:
<td><%= cats.image %></td>
<td><a type="button" data-toggle="modal" data-target="#editCategory" href="#">Edit</a>
// without using the modal above, I'll have to create a new page to edit only one item
// I think it's a waste of page space and bad UX, so I am going with the modal
<!--<a href="/admin/categories/edit-category/<%= cats._id %>">--> // I want to get the values from this id and show in the modal
<!--<button type="button" class="btn btn-primary btn-sm">Edit</button>-->
<!--</a>-->
</td>
When I click on the edit button, I want to get the id of the item and retrieve it's values to display in the modal.
Here's the full modal view:
<!-- Edit Category Modal -->
<div class="modal fade" id="editCategory" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<form action="/admin/categories/edit-cateory/<%= %>" method="post" enctype="multipart/form-data">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span> </button>
<h4 class="modal-title" id="myEditCategoryLabel">Edit Category</h4>
</div>
<div class="modal-body">
<div class="form-group">
<label>Title</label>
// this value should come from the category id but don't know how to pass it
<input value="<%= %>" name="title" class="form-control" type="text" placeholder="Category Title"> <br>
<label>Upload Image</label>
<input class="form-control selImg" type="file" accept="image/*" onchange="showImage.call(this)">
<img src="#" class="imgPreview" style="display: none; height: 100px; width: 100px">
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-primary">Save Edits</button>
</div>
</form>
</div>
</div>
</div>
How can I pass the data from mongodb to the modal using ejs?
Any help will be much appreciated.
Store your ID somewhere: hidden inputs or data-attributes.
<tr data-id="<%= cats.id %>">
<td><%= cats.image %></td>
<td>
<a type="button" class="edit" href="#">Edit</a>
</td>
</tr>
Then, create an onclick event handler such that, upon clicking on the button,
it will fetch the extra data via AJAX and open the modal dynamically after you get a response.
$('a.edit').click(function (e) {
e.preventDefault();
var tr = $(this).closest('tr'),
modal = $('#editCategory');
// make AJAX call passing the ID
$.getJSON('/admin/categories/get-cateory/' + tr.data('id'), function (data) {
// set values in modal
modal.find('form').attr('action', '/admin/categories/get-cateory/' + tr.data('id') );
modal.find('[name=title]').val( data.title );
// open modal
modal.modal('show');
});
});
You will need to create a route for fetching a single object (I'll leave that to you)
app.get('/admin/categories/get-cateory/:id', function (req, res) {
// TODO: fetch data using passed ID
// once you have the data, simply send the JSON back
res.json(data);
});

Render list action in modal sonata admin

I try to render the list action of my admin class in sonata in a modal, but I can't find the right way to do it?
Someone can help me please?
I just want the datagrid and not all the page(menu, topbar,etc...).
Actually i doing this like that :
En Cours modal
<div class="modal fade" id="basicModal1" tabindex="-1" role="dialog" aria-labelledby="basicModal" 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">&times;</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">
{{render (controller('MonBundle:Controller:list',{'id':object.id}))}}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
But I've got this error with the render :
Error: Call to a member function getRelativePath() on null
Whole page is shown because you are including a template of the standard controller action. Sonata use conditions for app.request.isXmlHttpRequest to detect if the view is opened in modal (via AJAX) or in a standard way.
So you may solve your problem by these steps:
1) Bind JS function (which opens modal) on button click.
2) When button clicked, load URL and paste its response body into .modal-body
URL: {{ path('your-list-action-name', {'id': object.id}) }}
It will solve the problem when you add a new record to the list from your page but list will show old records (because in your snippet, list renders once, on modal first render).
Additional info could be found in Sonata's ORM Admin Bundle (if you use ORM) under Resources/views/CRUD/edit_orm_many_association_script.html.twig
