truncate javascript multiple lines not working - javascript

I am using truncate.js (https://github.com/jeffchan/truncate.js) to put ellipsis into a text when it overflows. It is not working when I am following the demo right I think. Here is my code:
CSHTML File:
<div id="yammerDiv">
<div id="yammerHeader">
<img src="https://upload.wikimedia.org/wikipedia/commons/1/1f/Yammer_logo.png" alt="Yammer" height="20px;" width="50%">
</div>
<div id="yammerMessages" data-truncate-lines="3" data-toggle="modal" data-target="#myModal" style="margin-top: 25px;">
<img id="loading-gif" src="http://i559.photobucket.com/albums/ss36/madszckey01/speakker/buffering.gif">
<span id="message"></span>
<p id="sender"></p>
</div>
<div id="yammerButtons" style="display:none">
<button id="previous" type="button" class="btn btn-default btn-xs" aria-label="Left Align" onclick="onPrevious()">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
</button>
<input type="checkbox" id="myCheck" onclick="autoscroll()" data-toggle='tooltip' data-placement='bottom' data-original-title="Auto-Scroll" class='checkbox'>
<button id="next" type="button" class="btn btn-default btn-xs" aria-label="Right Align" onclick="onNext()">
<span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
</button>
</div>
JavaScript inside the CSHTML file:
$('#yammerMessages').truncate({
lines: 3,
lineHeight: 1.5
});
I want to truncate the text in the yammerMessages div and its not working as the text just continues through the height limit of the width.
EDIT:
I have got the truncate method working but my content inside the span element 'message' reloads text often and how do I keep truncating it every time it changes?
$('#yammerMessages').truncate({
lines: 7,
lineHeight: 14
});
This truncates the text inside the div once, but when the content changes in 'message', it won't let me truncate again.
SOLVED:
Look for my answer below.

Since this library would not solve my problem, I just ended up using dotdotdot jquery library which solved my issue.
To truncate for the div, I used the dotdotdot method:
$("#text-wrapper").dotdotdot({ wrap: 'letter' });
Then when the text changes inside the div, I use the trigger method which then deletes the truncation of the element it was called on:
$("#text-wrapper").trigger("destroy");
Then I simply truncate again the new text loaded inside the div:
$("#text-wrapper").dotdotdot({ wrap: 'letter' });

How can I get title attribute of clicked button?

I'm working on small angular project, and there are 3 buttons on my form, I would like to receive their title when they are clicked. They are clicked normally one by one, what I've tried so far:
Here is my html:
<div class="extra-btns">
<button type="button" title="Title 1" (click)="getMyTitleOne($event)" class="btn xbutton-square" style="font-size: 16px;"><i class="fas fa-newspaper fa-fw"></i></button>
<button type="button" title="Title 2" (click)="getMyTitleTwo($event)" class="btn xbutton-square"><i class="fas fa-fw"></i></button>
</div>
My typescript code:
getMyTitleOne($event) {
console.log($event.target.title);
}
getMyTitleTwo($event) {
console.log($event.target.title);
}
But in my console sometimes I get values and sometimes I don't, very weird, but most of the time values are undefined:
Thanks guys
Cheers
use template variables :
<button #button1 (click)="log(button1.title)" title="Hello, world !">Click me !</button>

Edit items by clicking a button. Angular.js

I currently have a directive to dynamically edit a field. I have in the header of the accordion a field to edit and another field in the content of the accordion. If I click the edit button, the fields in the respective row can be edited, and this works fine. My problem is when I save or when I cancel it (when I click on the save or cancel button) immediately disappears the text field of both the header and the contents of the header. I need the text field ONLY disappear for the item in which I am going to save or cancel. When you click on the edit button, the 2 text fields should appear in both the header and the content (this works). And when clicking save or cancel, the text field in the selected element should disappear / appear.

use one-way (one-directional) binding for editState
scope: {
model: '=ngModel',
editState: '<'
},

I believe you'll need to manage two separate booleans at the controller level so one directive doesn't overwrite the status of the other and then you have to set both booleans with your open button. I kept the master state so your glyph button will open or close both and the save/cancel should operate independently of each other.
$scope.editState = false;
$scope.editHeader = false;
$scope.editBody = false;
$scope.toggleEditState = function(index, val) {
debugger;
$scope.editState = !$scope.editState;
$scope.faqs[index].editHeader = $scope.editState;
$scope.faqs[index].editBody = $scope.editState;
}
<div ng-repeat="faq in faqs">
<div class="col-sm-11" >
<div uib-accordion-group class="panel-default" is-open="faq.open">
<uib-accordion-heading >
<span ng-click="ignoreClick($event);" ><a href='' click-to-edit edit-state='faq.editHeader' ng-model='faq.pregunta' typeinput='textarea' >{{faq.pregunta}}</a></span> <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': faq.open, 'glyphicon-chevron-right': !faq.open}"></i>
</uib-accordion-heading>
<span click-to-edit edit-state='faq.editBody' ng-model="faq.respuesta" >{{faq.respuesta}}</span>
</div>
</div>
<div class="col-sm-1" >
<button type="button" ng-click="toggleEditState($index)" class="btn btn-default">
<span class="glyphicon glyphicon glyphicon-edit"></span>
</button>
</div>

You could also communicate the master status with the directives if you wanted their input fields to open and close both.

Changes in html template do not reflect

I am trying to add some buttons to the GeoNetwork 3 MapViewer. Unfortunately I'm new to AngularJS, which GN3 is written in. So what I've done is editing the html-template that the 'gnMainViewer' directive is using.
ViewerDirectve.js:
module.directive('gnMainViewer', [
'gnMap',
function(gnMap) {
return {
restrict: 'A',
replace: true,
scope: true,
templateUrl: '../../catalog/components/viewer/' +
'partials/mainviewer.html',
[...]
}]);
In this template I can find the buttons that are shown in the MapView.
mainviewer.html:
<div class="wrapper" data-ng-controller="gnViewerController">
<div data-gn-alert-manager=""></div>
<div id="map" ngeo-map="map" class="map"></div>
<div gn-gfi="" map="map"></div>
<div gn-localisation-input map="map"></div>
<!--Top right buttons - Tools-->
<div class="tools tools-right" gi-btn-group gnv-close-panel data-ng-controller="toolsController">
<button class="btn btn-default" ng-model="activeTools.addLayers" type="submit"
rel="#addLayers" gi-btn gnv-tools-btn>
<span class="fa fa-plus"></span>
<span role="tooltip" data-translate="">addLayers</span>
</button>
<button class="btn btn-default" ng-model="activeTools.layers" type="submit"
rel="#layers" gi-btn gnv-tools-btn>
<span class="fa fa-tasks"></span>
<span role="tooltip" data-translate="">Layers</span>
</button>
[...]
</div>
</div>
So I've added a button let's say:
<button class="btn btn-default" ng-model="" type="submit"
rel="#" gi-btn gnv-tools-btn>
<span class="fa fa-beer"></span>
<span role="tooltip">NewButton</span>
</button>
to the template.
Then I've saved my changed and refreshed the MapView-Page on my server. But a new button will not be displayed. Also, changing the comment "Top right buttons" to something else will not make any changes to the displayed MapView-Page.
Even restarting the server won't change anything.
Could somebody explain me why AngularJS reacts like this? Any Ideas?
Turned out I had to run the page in debug mode e.g. http://localhost:8080/geonetwork/srv/ger/catalog.search?debug#/map
to force to load all AngularJS files seperately and without cache.

(Bootstrap 3.1.1) popover on show reset my addClass?

<button id="search-district" type="button" class="btn btn-sm btn-success" data-toggle="popover" data-placement="bottom" title="<a href='#' class='pull-right popover-close' onclick='$("#search-district").popover("hide");'>×</a>" data-html="true" data-content="
<a id='id_district_100' href='#' onclick='ChangeDistrictSelection("100");'>District123</a>
"><span class="glyphicon glyphicon-plus"></span> Dsitricts <span id="district_bracket" style="display:none;">[<span id="count_districts_">0</span>]</span></button>
and JavaScript function
function ChangeDistrictSelection(id)
{
$('#id_district_'+id).addClass("selected");
}
When I'm clicked to District123, my JavaScript add Class "active"... But, after that when action popover on show, popover reset my class :(
What ever your selected css is you have to mark it with !important in order to override existing one.
Example
.selected {
background-color:gray !important;
}
Your question is not clear much. Please explain it we can help you so.
And also please not this also.
You are passing '100' to the function using onclick and then you are trying to get the element by id. But is already is equal to the id.
WHY??
You are doing wrong here. See your codes.
<a id='id_district_100' href='#' onclick='ChangeDistrictSelection("100");'>District123</a>
and you function also have a look
function ChangeDistrictSelection(id) {
//id will be 100 as your code.
//again you are trying to get the element by id. see your html <a id="id_district_100">
//It's already equal to $('#id_district_'+100) - why do you passing that 100 and trying to get element by id??
$('#id_district_'+id).addClass("selected");
}
If you want to add the class to that element you can use this.
function ChangeDistrictSelection(id){
//alert(id);
$(id).addClass('selected');
}
In html pass like that
<a id='id_district_100' href="#" onclick='ChangeDistrictSelection(id)'>District123</a>
ok... v2
html:
<button id="search-district" type="button" class="btn btn-sm btn-success" data-toggle="popover" data-placement="bottom" title="<a href='#' class='pull-right popover-close' onclick='$("#search-district").popover("hide");'>×</a>‌​" data-html="true" data-content=" <a id='id_district_100' href='#' onclick='ChangeDistrictSelectionCss("100");'>District123</a> ... ">
js:
function ChangeDistrictSelectionCSS(id){
$('#id_district_'+id).css("color","red");
}
It's work, but when clicked button (id="search-district") again, css color is not red

How to get a tooltip to appear in a popover?

On my machine, this code produces a tooltip on hover over a bootstrap glyphicon:
<span class="glyphicon glyphicon-info-sign tt" data-toggle="tooltip" data-placement="top" title="" data-original-title="Tooltip on top"> </span>
However when I stack the tooltip inside a popover, the code used to generate a tooltip on its own no longer produces a tooltip:
<a href="#" class="example" data-toggle="popover" >Experiment</a>
<div id="popover_content_wrapper" style="display: none">
<a href="">
<span class="glyphicon glyphicon-info-sign tt" data-toggle="tooltip" data-placement="top" title="" data-original-title="Tooltip on top"> </span>
</a>
</div>
Here's how I'm triggering the popover and tooltip in the javascript (below these html elements)
<script>
$('.tt').tooltip();
$('.example').popover({
trigger: 'hover click',
html: true,
content: function() {
return $('#popover_content_wrapper').html();
},
placement: 'top',
delay: { show: 500, hide: 1000 }
});
</script>
Any ideas on how to get a tooltip to appear on an element inside a popover?
The problem is that the .tt classed element that appears in your popover is not the same one used to bind .tooltip() to.
You need to use the delegation model via the selector option, eg
$(document).tooltip({
selector: '.tt'
});
