load file with addEventListener - javascript

I use Backbone to create a menu in my app where I can open a project:
app.Tools = Class.extend({
init: function(elementId, app, view) {
this.html = $("#" + elementId);
this.view = view;
this.app = app;
this.openButton = $('<li><button data-toggle="modal" data-target="#openProject" class="btn btn-primary nav-item nav-link" title="Open"><i class="glyphicon glyphicon-folder-open" aria-hidden="true"></i></button></li>');
this.html.append(this.openButton);
this.openButton.click($.proxy(function(){
if (!document.getElementById('openProject')) {
//modal view to confirm new project
this.html.append(
`<div class="modal fade" id="openProject" tabindex="-1" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<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">Open a project</h4>
</div>
<div class="modal-body">
<span class="glyphicon glyphicon-warning-sign"></span> <p>Are you sure you want to do this? If you didn\'nt save your actual project, all your work will be lost for ever.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<span class="btn btn-primary btn-file">Open project<input id="open-project-butt" type="file" class="btn btn-primary"></span>
</div>
</div>
</div>
</div>`
);
};
//listen for new inputs
document.getElementById('open-project-butt').addEventListener('change', readSingleFile, false);
function readSingleFile() {
$('#openProject').modal('hide');
app.view.clear();
newProject(app.view);
var file = this.files[0];
if (!file) {
return;
}
var reader = new FileReader();
reader.onload = function() {
//parse result of the upload
var parsed = new DOMParser().parseFromString(this.result, "text/xml");
var stringXML = (new XMLSerializer()).serializeToString(parsed);
}
}
reader.readAsText(file);
}
},this));
}
});
The first time I open a file everything works fine. Problem is the readSingleFile() function is called as many times as files I open.
I created a codepen but it works fine without Backbone.
Any help or lead to solve the issue? Thanks.

Well, your mistake is adding event listener inside function on button click. You should move it out of click handler.
Each click will add a new listener. Function will be called as many times as you click.

making modal for every entry in a list view using Js?

I have a page where multiple images are present and I want to make the users able to crop any of them so I made a for loop to make a modal for each image and I looped the js function also.
this is my modal.
{% for image in Patient_detail.images.all %}
<div class="modal fade" id="modalCrop{{image.pk}}">
<div class="modal-dialog">
<div class="modal-content">
<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">Crop the photo</h4>
</div>
<div class="modal-body">
<img src="" id="image{{image.pk}}" style="max-width: 100%;">
</div>
<div class="modal-footer">
<div class="btn-group pull-left" role="group">
<button type="button" class="btn btn-default js-zoom-in">
<span class="glyphicon glyphicon-zoom-in"></span>
</button>
<button type="button" class="btn btn-default js-zoom-out">
<span class="glyphicon glyphicon-zoom-out"></span>
</button>
</div>
<button type="button" class="btn btn-default" data-dismiss="modal">Nevermind</button>
<button type="button" class="btn btn-primary js-crop-and-upload">Crop and upload</button>
</div>
</div>
</div>
</div>
{% endfor %}
and here's the function I used
{% for image in Patient_detail.images.all %}
$(function () {
/* SCRIPT TO OPEN THE MODAL WITH THE PREVIEW */
$("#crop{{image.pk}}").click(function () {
var img_src = document.getElementById("img{{image.pk}}").src
$("#image{{image.pk}}").attr("src", img_src);
$("#modalCrop{{imahge.pk}}").modal("show");
}
});
/* SCRIPTS TO HANDLE THE CROPPER BOX */
var $image = $("#image{{image.pk}}");
var cropBoxData;
var canvasData;
$("#modalCrop{{image.pk}}").on("shown.bs.modal", function () {
$image.cropper({
viewMode: 1,
aspectRatio: 1/1,
minCropBoxWidth: 200,
minCropBoxHeight: 200,
ready: function () {
$image.cropper("setCanvasData", canvasData);
$image.cropper("setCropBoxData", cropBoxData);
}
});
}).on("hidden.bs.modal", function () {
cropBoxData = $image.cropper("getCropBoxData");
canvasData = $image.cropper("getCanvasData");
$image.cropper("destroy");
});
$(".js-zoom-in").click(function () {
$image.cropper("zoom", 0.1);
});
$(".js-zoom-out").click(function () {
$image.cropper("zoom", -0.1);
});
/* SCRIPT TO COLLECT THE DATA AND POST TO THE SERVER */
$(".js-crop-and-upload").click(function () {
var cropData = $image.cropper("getData");
$("#id_x{{image.pk}}").val(cropData["x"]);
$("#id_y{{image.pk}}").val(cropData["y"]);
$("#id_height{{image.pk}}").val(cropData["height"]);
$("#id_width{{image.pk}}").val(cropData["width"]);
$("#formUpload{{image.pk}}").submit();
});
});
{% endfor %}
but the problem is the modal never shows so I don't really get what's the problem ?
what should I do to make this work is the problem with the first function to show the modal is there easier way to do this all i want is the users to be able to specify a part of the image they want ?

Modify data in a modal window when loading it

I have a presentation with user notes. The button processing works for me, a modal window appears. Now I need to set its title and body when downloading. I get the body from the parent class of the button, no problem with that.
Here is my code:
const buttons = Array.from(document.querySelectorAll('.card .btn-info'));
function heangleClick() {
const parent = this.parentNode;
console.log($(this).parent().find('.fullBody').html());
$('#exampleModalCenter').modal('show');
$('#exampleModalLongTitle').val('123'); // not work
};
buttons.forEach((button) => {
button.addEventListener('click', heangleClick);
});
<div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
<div class="modal-dialog modal-dialog-centered" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">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">
...
</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>
<script src="~/js/showTittleTodo.js"></script>
How can i set values ​​in js file exampleModalLongTitle and modalBody
You try below which is not work.
$('#exampleModalLongTitle').val('123');// not work
Please replace below instead of that
$('#exampleModalLongTitle').text('123');
Try to set html or text instead val.
$('#exampleModalLongTitle').html('123');
try with this code:
$('#exampleModalCenter').modal('show');
$('#exampleModalCenter').on('shown.bs.modal', function() {
$('#exampleModalLongTitle').val('123');
})
Update your js as following, using shown.bs.modal event on modal element you can attach a callback which fires when the modal window is completely shown
const buttons = Array.from(document.querySelectorAll('.card .btn-info'));
function heangleClick() {
const parent = this.parentNode;
console.log($(this).parent().find('.fullBody').html());
$('#exampleModalCenter').one('shown.bs.modal', function() {
$('#exampleModalLongTitle').val('123');
})
$('#exampleModalCenter').modal('show');
};
buttons.forEach((button) => {
button.addEventListener('click', heangleClick);
});

Can't load 2 different modal forms with JQuery Trigger

I have some modal forms to complete some fields, in this case I have 2 modal forms, 1 for Jury and 1 for Contact, when I press 'Add' link, in both cases works fine, but the problem is when I want to edit contact.
When I press Edit in both cases I call controller to complete the Java form and then, return to view and simulate a click in "Add" button with JQuery. In jury case works fine, but in Contact I only get a dark screen (like if modal works), but modal window never appear. Other problem is, when I press Edit button in Jury and then close the jury modal form, when I press Edit in Contact it launch the jury modal form...

P.S. addJury(); and addContactForm(); only closes modal window, both works fine!

Boostrap modal not loading when wired using jquery

I have the following link and I'm trying to load a bootstrap modal when its clicked but the javascript function doesnt seem to be firing. Instead of the view loading inside a modal, its loading as a new page?
#*this is the modal definition*#
<div class="modal hide fade in" id="report-summary">
<div id="report-summary-container"></div>
</div>
<script >
$('a.js-report-summary').click(function (e) {
var url = $(this).attr('href'); // the url to the controller
e.preventDefault();
$.get(url, function (data) {
$('#report-summary-container').html(data);
$('#report-summary').modal('show');
});
});
</script>
public ActionResult ReportSummary()
{
// some actions
return PartialView("ReportSummary", viewmodel)
}
// Report summary view which contains modal
<div class="modal-dialog" role="document">
<div class="modal-content">
<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="myModalLabel">#ViewBag.FormName - Analysis</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary" data-dismiss="modal">
Close</button>
</div>
</div>
</div>
There are no errors showing in the console either so why isn't the jquery function firing?
in your click function, add parameter e this will stand for event
then in the function itself add e.preventDefault() This will stop the refreshing effect.
on your controller method try
public ViewResult ReportSummary()
{
// some actions
if(Request.IsAjaxRequest())
return PartialView("ReportSummary", viewmodel);
else
return View("ReportSummary", viewmodel);
}
on your view
$('#exampleModal').on('show.bs.modal', function (event) {//give your model wrapper an id
//do some ajax and get html
$.ajax({
url:'',
success:function(data){
$('#report-summary-container').html(data);
}
});
})
on your anchor tag, add data-toggle="modal" data-target="#exampleModal"
if you dont want to use bootstrap events trigger your modal with
$('#myModal').modal('show')

Function to append modal

I have 3 modals that all have the same format and are activated by different onclicks (Create Contact, Update Contact, Delete Contact). I am wanting the modal-title and modal-body to change depending on which button was clicked. How would I go about creating a function that appends the modal content depending on which button was clicked? Thank you for your help!
<div id="myModal" class="modal fade">
<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">Confirmation</h4>
</div>
<div class="modal-body">
<p>Contact Created!</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">OK</button>
</div>
</div>
</div>
I have written the JavaScript "BootstrapModel" class for the same purpose.
It also depends on jQuery so don't forget to embed jQuery before using this class.
class is :
var BootstrapModal = (function (options) {
var defaults = {
modalId: "#confirmModal",
btnClose: "#btnClose",
title: "Confirm",
content: "Some bootstrap content",
onClose: function () {
},
onSave: function () {
}
};
defaults = options || defaults;
var $modalObj = $(defaults.modalId);
var hideModal = function () {
$modalObj.modal("hide");
};
var showModal = function () {
$modalObj.modal("show");
};
var updateModalTitle = function (title) {
defaults.title = title;
//$($modalObj).find(".modal-title").eq(0).html(title);
$modalObj.find(".modal-title").eq(0).html(title);
};
var updateModalBody = function (content) {
defaults.content = content;
$modalObj.find(".modal-body").eq(0).html(content);
};
return {
getDefaults: function () {
return defaults;
},
hide: function () {
hideModal();
},
show: function () {
showModal();
},
updateTitle: function (title) {
updateModalTitle(title);
return this;
},
updateBody: function (body) {
updateModalBody(body);
return this;
}
}
});
Usage :
var emailModal = new BootstrapModal({modalId: "#confirmModal"});
emailModal.updateTitle("Mail sent successfully").updateBody("<br/>This box will automatically close after 3 seconds.").show();
// Hide the Modal
emailModal.hide();
HTML Structure for the Modal:
<div class="modal fade" id="confirmModal" role="dialog" aria-labelledby="thankyouModal" aria-hidden="true" style="overflow-y: hidden;">
<div class="modal-dialog" style="padding-top: 225px">
<div class="modal-content">
<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="thankyouModal">Thank you</h4>
</div>
<div class="modal-body">
Thank you. We'll let you know once we are up.
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
The way I got around this is by loading the data in from external files. So you'd have your initial declaration of your modal box (just the surrounding div), and then in each file you have the containing code for the rest of the modal, then use a bit of jQuery to fire them off:
HTML (in main file)
<div class="modal" id="modal-results" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
</div>
JQuery
$('#create-contact').click(function(){
e.preventDefault();
$("#modal-results").html('create-contact.html');
$("#modal-results").modal('show');
});
