I can´t remove the last item of array

I can remove any item of array unless the last one. I also use angularjs to show information in the view. I don´t know what is happening with the last item of this array. Please, anyone can help me?
Here is HTML:
<div class="row">
<div class="col-md-12">
<h4><strong>Documento {{index + 1}} de {{documentos.length}}:</strong> {{documentos[index].nome}}</h4>
<iframe style="background: #ccc;" ng-show="exibirPreview" frameborder="0" ng-src="{{versaoLink}}" width="100%" height="300px"></iframe>
<div class="alert alert-warning" ng-hide="exibirPreview">
#Html.Raw(Resources.Dialog.SignDocuments.TypeDocumentCanNotPreDisplayed)
</div>
<hr />
<div class="pull-right btn-row" ng-show="documentos.length > 1">
<button class="btn btn-default" type="button" ng-click="RemoveDoc(index)"><i class="fa fa-fw fa-times"></i> #Resources.Common.RemoveDocList</button>
</div>
</div>
</div>
Here is js/angularjs
$scope.documentos = [
{nome:"document1", chave: "8F65579E3737706F", extensao:".pdf"},
{nome:"document2", chave: "8F65579E3730007F", extensao:".pdf"},
{nome:"document3", chave: "8545579E3737706F", extensao:".pdf"},
{nome:"document4", chave: "8555579E3730007F", extensao:".pdf"}
]
$scope.ViewLink = function () {
var versao = $scope.documentos[$scope.index];
$scope.exibirPreview = versao.extensao == ".pdf" || versao.extensao == ".txt";
if (!$scope.exibirPreview) {
$scope.versaoLink = '';
} else {
$scope.versaoLink = '/Documento/VersaoView?chave=' + versao.chave;
}
};
$scope.ViewLink();
$scope.RemoveDoc = function (index) {
$scope.documentos.splice(index, 1);
$scope.ViewLink();
};
Or Plunker

In your HTML you are preventing the deletion of the last element:
<div class="pull-right btn-row" ng-show="documentos.length > 1">
<!-- -->
</div>
documentos.length > 1 means "hide when it reaches one item in the array".
It should be documentos.length == 0.
It's either this or your index value starts from 1 and not from 0.

The simplest solution would be to change your remove function to take in the document instead of the index. Try this:
$scope.RemoveDoc = function(document) {
var index = $scope.documents.indexOf(document);
$scope.documents.splice(index, 1);
}
in view:
<button class="btn" type="button" ng-click="RemoveDoc(document)">Delete</button>

Load More Button JS - Load new content on page

I'm trying to develop a Load-More button using Javascript calling an API done with PHP.
So far, so good. I can load the new objects in a range i += i + 4 (I load three new comments everytime I press the button).
This is my load-more button:
$(document).ready(function () {
$(".load-more").on('click', function () {
var tab = $(this).data('tab');
var next_page = $(this).data('next-page');
console.log(next_page);
console.log(tab);
$.get($(this).data('url') + '?tab=' + tab + '&page=' + next_page, function (data) {
addNewQuestions($.parseJSON(data));
});
});
});
And for every object loaded I want to print each of these html blocks.
<div class="question-summary narrow">
<div class="col-md-12">
<div class="votes">
<div class="mini-counts"><span title="7 votes">
{if $question['votes_count']}
{$question['votes_count']}
{else}
0
{/if}
</span></div>
<div>votes</div>
</div>
<div {if $question['solved_date']}
class="status answered-accepted"
{else}
class="status answer-selected"
{/if}
title="one of the answers was accepted as the correct answer">
<div class="mini-counts"><span title="1 answer">{$question['answers_count']}</span></div>
<div>answer</div>
</div>
<div class="views">
<div class="mini-counts"><span title="140 views">{$question['views_counter']}</span></div>
<div>views</div>
</div>
<div class="summary">
<h3>
<a href="{questionUrl($question['publicationid'])}" class="question-title" style="font-size: 15px; line-height: 1.4; margin-bottom: .5em;">
{$question['title']}
</a>
</h3>
</div>
<div class = "statistics col-sm-12 text-right" style="padding-top: 8px">
<span>
<i class = "glyphicon glyphicon-time"></i>
<span class="question-updated-at">{$question['creation_date']}</span>
</span>
<span>
<i class = "glyphicon glyphicon-comment"></i>
<span class="question-answers">{$question['answers_count']}</span>
</span>
</div>
</div>
</div>
The problem is that I have several conditions, as {if$question['votes_count']} and I'm struggling because I don't know how get those variables when rendering the html.
Then I found something but I can't figure out how to adapt to my case
On that addNewQuestions I think that a good approach would be:
function addNewQuestions(objects) {
$.each(objects, function (i, object) {
console.log(object);
var lastItem = $('div.active[role="tabpanel"] .question-line:last');
var newLine = lastItem.clone(true);
var newObject = newLine.find('.question-col:eq(' + i + ')');
newObject.find('.question-info-container').attr('data-id', object.publicationid);
newObject.find('.vote-count').html(object.votes);
updateTitleAndLink(newObject.find('.question-title'), object);
lastItem.after(newLine);
});
}
function updateTitleAndLink(questionTitle, object) {
questionTitle.attr('href', questionTitle.data('base-question-url') + object.publicationid);
questionTitle.html(object.title);
}
But nothing happens and I can't figure out why.
Any idea or suggestion?
Kind regards

Bind paired data in object to another element outside ng-repeat - angular

I have this array of objects that I need to work with:
$scope.pdfs = [
{ "pdf_title": "Corporate Hire", "attached_file": "http://file1.jpg"},
{ "pdf_title": "Wedding Hire", "attached_file": "http://file2.jpg"},
{ "pdf_title": "Filming Hire", "attached_file": "http://file3.jpg"}
];
The pdf_file value is ng-repeated in li's.
What I want to do is if that li is clicked, to push its paired to another div, say the src for an href.
Here are my workings, but not quite correct:
Controller function:
$scope.bindWithFile = function(value) {
var currentValue = $scope.corpResult = value;
// pdfs support
var pdfs = $scope.pdfs;
for (var i = pdfs.length - 1; i >= 0; i--) {
if (currentValue == hasOwnProperty(key[pdfs])) {
value[pdfs] = $scope.corpLinkHref;
}
};
Markup:
<div class="w-12" ng-controller="corpHireController">
<div class="c-6-set">
<ul>
<li ng-repeat="pdf in pdfs" class="col-7 link link-inherit" ng-click="bindWithFile(pdf.pdf_title)">{{::pdf.pdf_title}}</li>
</ul>
</div>
<div class="c-6-set">
<div class="w-12">
<i class="fs-4 col-7 icon icon-pdf"></i>
</div>
<span class="col-7 h4" ng-bind="corpResult"></span>
<button ng-href="{{::corpLinkHref}}" class="button green2-button smaller-letters full-width">Download</button>
</div>
</div>
What is needed:
Clicking on the titles on the left, binds the pdf_title under the pdf icon and binds the attached_file to the button's href

Instead of passing the title of the selected pdf, why not passing the whole object. This way you don't have to performance any find or search function.
Markup:
<div class="w-12" ng-controller="corpHireController">
<div class="c-6-set">
<ul>
<li ng-repeat="pdf in pdfs" class="col-7 link link-inherit"
ng-click="bindWithFile(pdf)">
{{::pdf.pdf_title}}
</li>
</ul>
</div>
<div class="c-6-set">
<div class="w-12">
<i class="fs-4 col-7 icon icon-pdf"></i>
</div>
<span class="col-7 h4" ng-bind="corpResult"></span>
<button ng-href="{{::corpLinkHref}}"
class="button green2-button smaller-letters full-width">
Download
</button>
</div>
</div>
Controller
$scope.bindWithFile = function(selectedPdf) {
$scope.corpResult = selectedPdf.pdf_title;
$scope.corpLinkHref = selectedPdf.attached_file;
}

How to submit a value of hidden input in Meteorjs

In my meteor app, I submit the value of the picker number by clicking sbmit button bellow
When I tried to submit it with Enter key (keyboard), it does not work, knowing that i set a hidden input and trying to submit it; I think the problem come from the hidden input so after a hours of search I don't know how to submit a hidden input, any help please; here my code
<template name="range">
<div class="row">
<div class="col-xs-9 col-sm-9 col-md-9 col-lg-9">
<div class="valueSliders">
<div class="verticleNumberSelect">
<span class="firstNumber">
<span class="up"> </span>
<span class="numberValue" tabindex="1">0</span>
<span class="down"></span>
</span>
<span class="secondNumber">
<span class="up"></span>
<span class="numberValue" tabindex="1">0</span>
<span class="down"></span>
</span>
<span class="thirdNumber">
<span class="up"></span>
<span class="numberValue" tabindex="1">0</span>
<span class="down"></span>
</span>
<span class="fourthNumber">
<span class="up"></span>
<span class="numberValue" tabindex="1">0</span>
<span class="down"></span>
</span>
<form>
<input type="hidden" id="verticleNumber" />
<input type="submit" style="visibility: hidden; position: absolute;" />
</form>
</div>
</div>
</div>
</template>
and my js is
Template.range.events({
'submit form': function (event) {
event.preventDefault();
if (Session.get('times') && Session.get('times') > 0) {
var RESPONSE, responseClass;
var GUESS = $('#verticleNumber').val();
if (GUESS > ANSWER) {
RESPONSE = "-";
responseClass = 'lower';
}
else if (GUESS < ANSWER) {
RESPONSE = "+";
responseClass = 'higher';
}
else if (GUESS == ANSWER) {
RESPONSE = "✔";
responseClass = 'win';
}
}
}
});
I set the value of hidden input dynamically and it's a value chosen by the player with picker number, I means the value of verticleNumber; answer it random value
Thank's a lot

The enter key only works on a form if it is considered focused - I think form only having one hidden input is preventing that from ever occurring. Assuming that your submit function is not being called at all, I'd actually break Meteor convention and do a jQuery event listener in your template's onCreated function:
$(document).keypress(function(e) {
if(e.which == 13) {
console.log('enter pressed');
// Your code here to get values and do stuff.
}
});

Is JQuery breaking my functionality?

I am making an app, the user can either select an item or use their camera to get the qr code which translates into an item's ID.
The problem is that I think some JQuery is messing with my scope from working properly.
I have to get the QR code by listening to an innerHtml change, once it changes (DOMSubtreeModified) the following occurs.
var index = 0;
$('#result').one('DOMSubtreeModified', function(e) {
var code = "";
if (e.target.innerHTML.length > 0) {
code = e.target.innerHTML;
$scope.ToRun(code);
}
});
$scope.ToRun = function(code) {
for (i = 0; i < $scope.plantList.length; i++) {
if ($scope.plantList[i].plantcode == code) {
index = i;
break;
}
}
$scope.currentPlant = $scope.plantList[index];
$scope.plantDetails = false;
$scope.searchDetails = true;
}
For some reason the following does not have any effect on my ng-classes. As when an item is selected I hide the input dialogs, and show the result one.
$scope.plantDetails = false;
$scope.searchDetails = true;
But when a user selects the item manually it works just perfectly. (the items have an ng-click on it)
$scope.viewPlant = function(plant) {
$scope.currentPlant = plant
$scope.plantDetails = false;
$scope.searchDetails = true;
};
And the above works fine, with the ng-click. So why won't my new function that listens for an innerHtml change work?
HTML snippet
<div ng-class="{ 'hidden': searchDetails }">
<!-- CHOOSE INPUT TYPE -->
<div class="form-group" style="margin-bottom:0px">
<div class="btn-group btn-group-justified">
<div class="btn-group">
<button type="button" class="btn btn-default" ng-click="digits = false; qr = true">Plant Code</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-default" ng-click="digits = true; qr = false">QR Code</button>
</div>
</div>
</div>
<br />
<!-- QR CODE INPUT -->
<div ng-class="{ 'hidden': qr }">
<img id="blah" src="./images/placeholder.png" />
<span class="btn btn-default btn-file">
<i class="glyphicon glyphicon-camera"></i>
<input type="file" onchange="readURL(this);handleFiles(this.files)">
</span>
<div id="result">xxxxxx</div>
<canvas id="qr-canvas" width="800" height="600"></canvas>
</div>
<!-- MANUAL SELECTION INPUT -->
<div ng-class="{ 'hidden': digits }">
<input ng-model="search.$" style="width:100%; font-size:30px; text-align:center" placeholder="Plant Code" />
<div style="overflow: auto; max-height:250px">
<table class="table table-striped" style="background-color:lightblue">
<tr ng-repeat="plant in plantList | filter:search" ng-click="viewPlant(plant)" style="cursor:pointer">
<th>{{plant.name}}</th>
<th>{{plant.plantcode}}</th>
</tr>
</table>
</div>
</div>
<div>
</div>
</div>
<div ng-class="{ 'hidden': plantDetails }">
// results - this should appear when one of the above is entered.
// works for manual selection, but not qr code
</div>
Just confused on why my QR input will not fire off the change-class options to hide the searchDetails div and show the plantDetails div
EDIT: Doing a small test, it seems that my class variables are indeed not updating at all. I just put the values at the bottom of my page and they do not update when hitting the block of:
$scope.plantDetails = false;
$scope.searchDetails = true;

You need to let Angular know about the change. Add this at the end of your method and let me know if it works.
$scope.$apply();
