HTML File Input Angularjs Select same File only fires ones - javascript

I've made a Angular directive to warp the a file upload input.
directive('ngFile', function () {
return {
link: function (scope, element, attrs) {
var button = element.find('button[data-fileInputButton]');
var inputElement = element.find('input[type="file"]');
var updateModel = function (evt) {
scope.$apply(function () {
scope.files = evt.target.files;
if (scope.startUpload) {
scope.startUpload();
}
evtl.target.files = [];
});
}
inputElement.bind('change', updateModel);
button.click(function () {
var input = element.find('input[type="file"]');
input.click();
});
}
}
});
When I click and select a file, everything is OK. However, when I select the file again, the event is not fired. It is only fired when I select another file. Why is this happening?

The change is listening to the value and not to the files.
you need to do:
evt.target.value = "";
Good luck :)

Encapsulate function with submit and revealing module pattern

I am not sure if I understand this correctly.
The following example changes form action depending on a radio button selection. Then a javascript submit is executed.
I tried to build the whole thing after the revealing module pattern.
var myModule= (function () {
function makeSubmit() {
document.getElementById('form').addEventListener('submit', function(event){
event.preventDefault();
var form= document.getElementById('form'),
datasetURL = document.querySelector('input[name = "dataface"]:checked'),
actionURL = datasetURL.dataset.url,
searchterm= document.getElementById('searchterm').value,
submit;
(datasetURL.id == "db-01") ? submit = actionURL+searchterm: submit = actionURL;
form.action = submit;
form.submit();
});
}
return {
search: function () {
makeSubmit();
}
};
})();
$(document).ready(function () {
myModule.search();
});
My question is now whether this procedure is so correct.
Basically it works.
In this case you can pass private function as reference
return {
search: makesubmit
}
And invoke it as you did.

ng-change is not triggered (used along with a directive)

I have the following html code
<input type="file" ng-model="Import" file-reader="fileContent" ng-change="getList();"/>
As shown above, i am trying to load a text file and get it contents on ng-change.
Here is the directive 'fileReader'
ngUtilityMod.directive('fileReader', function () {
return {
scope: {
fileReader: "="
},
link: function (scope, element) {
$(element).on('change', function (changeEvent) {
var r = new FileReader();
var CSVfile;
var checkCSV = changeEvent.target.files[0].name;
checkCSV = checkCSV.slice(-4);
if (checkCSV === '.csv') {
CSVfile = true;
}
else { CSVfile = false; }
if (changeEvent.target.files[0].type === 'text/plain' || CSVfile === true) {
var files = changeEvent.target.files;
if (files.length) {
r.onload = function (e) {
var contents = e.target.result;
scope.$apply(function () {
scope.fileReader = contents;
});
};
r.readAsText(files[0]);
}
}
else {
'data';
}
});
}
};
});
When ng-change is triggered, i should be able to get to below function. The issue here is that ng-change is not getting triggered at all. If i use ng-click or any other angularjs events, it is able to detect. Can someone please let me know why i am unable to trigger ng-change here
$scope.getList = function () {
$scope.getImport = function (fileContent) {
} // function to load CSV data during import feature.
if (angular.isDefined($scope.fileContent)) {
$scope.Import = $scope.fileContent;
console.log($scope.params);
}
};

Pagedown markdown script inserts image url once

I have a modified pagedown markdown markup script for inserting image url to the editor but it works only the first time.
I have explained my code with comments
</script>
<script type="text/javascript">
(function () {
var converter = new Markdown.Converter();
var help = function () { window.open('http://mywebsite.com/editing-help'); }
var editor = new Markdown.Editor(converter);
editor.hooks.set('insertImageDialog', function(callback) {
setTimeout(function ()
{
//i use bootstrap dialog to enter the url
$('#fileModal').modal('show');
/*i have a button for clearing the textbox when i open
it the second time since when i open it the second
time the modal still contains what i had placed previously*/
$("#clear").on("click", function(e) {
e.preventDefault();
$("#imgt").val('');
$("#file").val('');
});
//the button that when clicked inserts the image url
$("#insert_image_post").on("click", function(e) {
e.preventDefault();
//the image file being inserted
if($("#imgt").val().length > 0)
{
var $url = $('input[type=text]');
var image = $("#imgt").val();
callback(image);
$("#fileModal").modal('hide');
}
});
}, 0);
return true; // tell the editor that we'll take care of getting the image url
});
editor.run();
})();
</script>
Any one with pagedown markdown javascript... ideas to help me understand where i am going wrong?
I managed to make it work
Its like markdown editor does not smoothly run the .on("click", function(e)... in my case. i.e.
$("#insert_image_post").on("click", function(e) {
e.preventDefault();
So i used theirs after going through their Markdown.Editor.js file i.e.
var thebtn = document.getElementById("insert_image_post");
thebtn.onclick = function () {
The full adjusted code below
<script>
(function () {
var converter = new Markdown.Converter();
var help = function () { window.open('http://stackoverflow.com/editing-help'); }
var editor = new Markdown.Editor(converter);
editor.hooks.set("insertImageDialog", function (callback) {
$('#fileModal').modal('show');
var thebtn = document.getElementById("insert_image_post");
thebtn.onclick = function () {
var images = $(".img-url").val();
callback(images)
$('#fileModal').modal('hide');
};
var theclear = document.getElementById("clear");
theclear.onclick = function () {
$("#imgt").val('');
$("#file").val('');
};
return true; // tell the editor that we'll take care of getting the image url
});
editor.run();
})();
</script>

Trigger check_variations event in Woocommerce

I'm trying to make a text based selection for my product variationon on my single product page.
I basically generate a p-tag for every option in every variation and use javascript to select the option in the default Woocommerce select dropdown. The option gets selected fine but the check_variations event doesn't get triggered.
Does anyone know how to trigger the check_variations event from my theme? The check_variations listener is in woocommerce/assets/js/frontend/add-to-cart-variation.js
JS
var ProductVariations = (function () {
function ProductVariations() {
this.$variationClickables = $('.variations .value p');
this.setupClickHandlers();
}
ProductVariations.prototype.setupClickHandlers = function () {
var _this = this;
this.$variationClickables.bind('click', function (event) {
_this.variationsClicked(event);
});
};
ProductVariations.prototype.variationsClicked = function (event) {
var $target = $(event.target);
var targetVariation = $target.attr('value');
$('option[value=' + targetVariation + ']', $target.closest('.variations')).attr('selected', 'true');
$target.closest('.variations_form').trigger('change');
};
return ProductVariations;
})();
Andreas!
Did you try this?
$('.variations_form').trigger('check_variations');

AngularJS : How to run JavaScript from inside Directive after directive is compiled and linked

I have a responsive template that I am trying to use with my Angularjs app. This is also my first Angular app so I know I have many mistakes and re-factoring in my future.
I have read enough about angular that I know DOM manipulations are suppose to go inside a directive.
I have a javascript object responsible for template re-sizes the side menu and basically the outer shell of the template. I moved all of this code into a directive and named it responsive-theme.
First I added all the methods that are being used and then I defined the App object at the bottom. I removed the function bodies to shorten the code.
Basically the object at the bottom is a helper object to use with all the methods.
var directive = angular.module('bac.directive-manager');
directive.directive('responsiveTheme', function() {

Originally the App.init() object method would be called at the bottom of any regular html page, and I have others that do certain things also that would be used on specific pages like Login.init() for the login page and so forth.
I did read that stackoverflow post
"Thinking in AngularJS" if I have a jQuery background? and realize that I am trying to go backwards in a sense, but I want to use this template that I have so I need to retro fit this solution.
I am trying to use this directive on my body tag.
<body ui-view="dashboard-shell" responsive-theme>
<div class="page-container">
<div class="page-sidebar nav-collapse collapse" ng-controller="SidemenuController">
<sidemenu></sidemenu>
</div>
<div class="page-content" ui-view="dashboard">
</div>
</div>
</body>
So here is my problem. This kinda sorta works. I don't get any console errors but when I try to use my side menu which the javascript for it is in the directive it doesn't work until I go inside the console and type App.init(). After that all of the template javascript works. I want to know how to do responsive theme stuff in these directives. I have tried using it both in the compile and link sections. I have tried putting the code in compile and link and calling the $scope.App.init() from a controller and also at the bottom after defining everything. I also tried putting this in jsfiddle but can't show a true example without having the console to call App.init().
My end design would be having some way to switch the pages through ui-router and when a route gets switched it calls the appropriate methods or re-runs the directive or something. The only method that will run on every page is the App.init() method and everything else is really page specific. And technically since this is a single page app the App.init() only needs to run once for the application. I have it tied to a parent template inside ui-router and the pages that will switch all use this shell template. There are some objects that need to access other to call their methods.
Im sorry in advance for maybe a confusing post. I am struggling right now trying to put together some of the ways that you do things from an angular perspective. I will continue to edit the post as I get responses to give further examples.
You said I have read enough about angular that I know DOM manipulations are suppose to go inside a directive but it sounds like you missed the point of a directive. A directive should handle DOM manipulation, yes, but not one directive for the entire page. Each element (or segment) of the page should have its own directive (assuming DOM manip needs to be done on that element) and then the $controller should handle the interactions between those elements and your data (or model).
You've created one gigantic directive and are trying to have it do way too much. Thankfully, you've kinda sorta designed your code in such a way that it shouldn't be too hard to break it up into several directives. Basically, each of your handle functions should be its own directive.
So you'd have something like:
.directive('sidebarMenu', function(){
return {
template: 'path/to/sidebar/partial.html',
link: function(scope, elem, attrs){
// insert the code for your 'handleSidebarMenu()' function here
}
};
})
.directive('horizontalMenu', function(){
return {
template: 'path/to/horizontal/partial.html',
link: function(scope, elem, attrs){
// insert the code for your 'handleHorizontalMenu()' function here
}
};
})
and then your view would look something like:
<body ui-view="dashboard-shell" responsive-theme>
<div class="page-container">
<div class="page-sidebar nav-collapse collapse">
<horizontal-menu></horizontal-menu>
<sidebar-menu></sidebar-menu>
</div>
<div class="page-content" ui-view="dashboard">
</div>
</div>
</body>
And then you don't need a SidebarmenuController because your controller functions shouldn't be handling DOM elements like the sidebar. The controller should just handling the data that you're going to display in your view, and then the view (or .html file) will handle the displaying and manipulation of that data by its use of the directives you've written.
Does that make sense? Just try breaking that huge directive up into many smaller directives that handle specific elements or specific tasks in the DOM.
