Is it possible to suppress Durandal navigation? - javascript

My web application makes use of bootstrap, knockout and durandal. Below is a snippet of the rendered html, that defines a row with five columns. Irrelevant details are left out.
<div class="row list-row" data-bind="click: function(vm, event) { $(event.currentTarget).trigger('durandal-navigation'); }">
<div class="col-xs-2">
...
</div>
<div class="col-xs-2">
...
</div>
<div class="col-xs-6">
...
</div>
<div class="col-xs-1">
...
</div>
<div class="col-xs-1">
<button class="btn btn-default btn-xs deletebutton" data-bind="click: DeleteClicked">
<i class="fa fa-trash"></i>
</button>
</div>
</div>
Now when the mouse hovers over any of those divs, the css in place lits up the entire row which is how it is supposed to be, and a click navigates to the desired screen with durandal. The latter, however, should not be the case when the user clicks the button in the last column: only the DeleteClicked function should fire.
Is there any way to suppress the navigation here?

I've found a quite simple way around it by using sessionStorage: DeleteClicked now contains the line
sessionStorage.setItem("cancelNavigation", true);
The part of the application that actually implements the navigation:
$(document.body).on('durandal-navigation', function (event) { ... }
...performs a check on the status of "cancelNavigation" before calling router.navigate(...); and in addition of course removes the cancelNavigation key from sessionStorage. Works perfectly!

Using a loading spinner in a Dynamics 365 embedded iframe web resource

I am trying to use a loading spinner in an embedded iframe in a Dynamics 365 application. I am using this library: https://loading.io/button/. I can see that the CSS loads properly, because it shows the spinning icon when had a class of running on the button/div element.
What I'm trying to do is add the "running" class to the button when it is clicked, so the user knows that an action is occurring and they should expect something to happen in the near future. However, when I have code that adds the "running" class to the button, it does not seem to work. Here's my code:
$("#retakeButton").on("click", function () {
$("#retakeButton").addClass('running');
\\\\\\ LOGIC GOES HERE \\\\\\
$("#retakeButton").removeClass('running');
});
And here is my HTML:
<div id="outerBorder" class="container embed-responsive ">
<div class="col-md-12" id="topbuttons">
<div class="btn-group btn-group-justified">
<div class="btn-group">
<div type="button" id="retakeButton" class="btn btn-primary hovering ld-over">
<strong>Take Photo</strong>
<div class="ld ld-ring ld-spin-fast"></div>
</div>
</div>
</div>
</div>
<div id="carousel" class="slideshow-container"></div>
<br>
<div id="dots" style="text-align:center"></div>
</div>
What is strange is that if I open the console and select the iframe as the target, I can get it to show the in progress animation by running $("#retakeButton").addClass('running');. However, it doesn't seem to work in the javascript that is referenced by the HTML.
I just tested this, its working.
For clear visibility, I added a border for div, also commented out the removeClass for testing (it may be too fast to notice).
<div id="div_loader" class="btn btn-default ld-ext-top" style="border:solid; font-size:2em">
<div class="ld ld-ring ld-spin-fast"></div>
</div>
$("#div_loader").on("click", function () {
$("#div_loader").addClass('running');
//do some logic
//$("#retakeButton").removeClass('running');
});
One last thing. Problem could be by class hovering - you can remove & test your code.

MVC #foreach and JavaScript Confusion

I'm trying to make a button in a Bootstrap popover that passes a Razor value to another JavaScript function called killDatabase when running through a Razor foreach. The code produces a list of buttons that you can select but I also want to be able to hit a button and delete one of the options. The code doesn't throw any errors, and everything works perfectly except the fact that any of the delete buttons will always delete the last element, not the one that it's supposed to be associated with. I'm assuming this is because the function gets called on an onclick and so at that point #str is just the last element's name, but I'm wondering if there's any way to store that value to be unique for each element? I've tried adding a JavaScript variable within the foreach but still ran into the same problem.
<div class="btn-group-vertical btn-block" data-toggle="buttons" id="btns">
#foreach (var str in Model)
{
<div id="popover-content" hidden>
Are you sure you would like to permanently delete this query from the database?<br />
<button onclick="killDatabase('#str')" class="btn btn-primary btn-sm" style="float:left; margin-bottom: 10px;">Yes</button>
<button class="btn btn-sm btn-primary" style="float:left;">No</button>
</div>
<label class="btn btn-default" style="height:auto">
<div class="form-group" style="height:auto; padding-bottom: 10px;">
<input type="radio" name="query" value="#str" />
<span class="pull-left">#str</span>
<span class="pull-right">
<button class="btn btn-sm btn-danger" style="margin-top:-2px;" data-toggle="popover" title="Confirm Deletion" data-placement="bottom">
<span class="glyphicon glyphicon-trash"></span></button></span>
</div>
</label>
}
</div>
So I'm going to close this question because it was me being really confused about AJAX. That's what it boiled down to: I had a bad AJAX call and I was trying to do things on a popover that was initialized after the page was loaded so any time I would try and use the #str value in that popup, it would only take the most recent value. I've reworked the code into a more streamlined, less buggy design, and it works fine now. Thanks to everyone who tried to help

Bootstrap multi-line button with badge

I'm working on a project with bootstrap and I'm trying to figure out how to get a button that shows:
-Text left aligned (pull-left makes sense here I think)
-A badge right aligned with a number (pull right makes sense here)
This works great but the problem is most of my buttons have names that are ideal for a two-line button. Everything looks great on one line but as soon as the text gets too long or the button gets too short, it kicks the text to another line and the top text looks centered instead of pulled left. This looks good:
<div style="width:300px;margin:10px">
<button type="button" class="btn btn-primary btn-block" style="font-weight:bold;white-space:normal;">
<span class="pull-left">Under Investigation </span><span class="badge pull-right">5</span>
</button>
</div>
This looks bad (button is too narrow, text on top doesn't pull left):
<div style="width:150px;margin:10px">
<button type="button" class="btn btn-primary btn-block" style="font-weight:bold;white-space:normal;display:inline-flex;">
<span class="pull-left">Under Investigation </span><span class="badge pull-right">5</span>
</button>
</div>
Fiddle: https://jsfiddle.net/rjerskine/ay9L512h/2/
Solution:
I ended up having to wrap the text in another div which is fine and works great when the window resizes. The text kicks to two lines and the badge stays on one line. I'll end up writing this with proper classes but here's the solution for anyone with a similar question:
<div class="col-sm-2">
<button type="button" class="btn btn-primary btn-block" style="font-weight:bold;">
<div class="pull-left" style="text-align:left;width:calc(100% - 30px);white-space:normal;overflow:hidden;">
Under Investigation
</div>
<span class="badge pull-right" style="display:inline-flex;">5</span>
</button>
</div>
Use text-align:left on that button.
button span.pull-left {
text-align: left
}
Fiddle

element reappears immediately after fadeOut()

I'm trying to fade out some buttons after they're clicked but they immediately reappear. This is in Phonegap 2.7 on Android 4.2. In Windows Chrome, the element stay hidden after they fade out. Can someone help me? I can post a video of the behavior if that would help explain things.
HTML
<div id='button-div' class='row'>
<div id='yes-outer' class='col-xs-5 col-xs-offset-1'>
<div class='button'>
<i class="glyphicon glyphicon-ok"></i>
<span>Yes</span>
</div>
</div>
<div id='no-outer' class='col-xs-5'>
<div class='button'>
<i class="glyphicon glyphicon-remove"></i>
<span>No</span>
</div>
</div>
</div>
JS
$('.button').unbind('click').bind('click',function() {
$('#button-div').fadeOut();
});
Thanks!
Try this:
$('.button')[0].onclick=function() {
$('#button-div').fadeOut();
}
You might add another function for fadeIn() and onClick. Both of them call immediately and cause that problem. In this method, you remove the functions list and replace it with that function.

Using Bootstrap, I can only get the text to act like a link, not the whole button?

I'm just learning how to use html and css and my teacher has asked us to use Bootstrap. It's really cool, obviously, but when I try to make a button, only the text within the button actually acts like a link as opposed to the whole rectangular button. I'm not sure if I need more than just the minified bootstrap javascript file to make them work or what.
Here's my html, and I also added the line "$('.nav-tabs').button()" to my head as well as the javascript file from bootstrap. Any advice? I know my html is probably pretty janky, my teacher isn't the best at explaining things so I've just been fiddling with things until they seem to work.
<div class="btn-toolbar">
<div class="row-fluid">
<div class="span2 offset2">
<div class="btn btn-primary">

remove the class="btn btn-primary" from the div tag, put it on the a tag
see http://twitter.github.com/bootstrap/base-css.html#buttons
...typically you'll want to apply these to only <a> and <button> elements for the best rendering.
Looks like you are not adding the class on the a tag.
You need to use something like this New button This should give you a button with the text New button.
You use Big Button
For a large blue button.
