Problems updating the content of a Kendo UI TabStrip without AJAX? - javascript

I have a small console that displayed the output of certain actions in my website, the need to have another console that would display a different kind of output made me want to combine both consoles in a Kendo UI TabStrip, the thing is that the information displayed on the console isn't received with AJAX so when I started to insert the HTML elements like before, the tab didn't got updated.
This is how I initialize the tab:
$('#tabConsole').kendoTabStrip({
animation: {
open: {
effects:'fadeIn'
}
}
});
This is how my HTML looks:
<div id="tabConsole">
<ul>
<li class="k-state-active">Salida</li>
<li id="notificacionTab">Notificaciones</li>
</ul>
<div id="userConsole"></div>
<div id="notificationConsole"></div>
</div>
This is how I try to update it:
function appendToConsole(content, type, optional) {
//code to append to console
var actualDate = new Date();
var prevContent = $('#userConsole').html();
if (typeof prevContent === 'undefined') {
prevContent = '';
}
var strType = '';
var iconType = '';
var moreOutput = '';
if (type == 1) {
strType = 'infoConsole';
iconType = 'infoIcon.png';
} else if (type == 2) {
strType = 'warningConsole';
iconType = 'warningIcon.png';
moreOutput = '<img id="viewDetails" value="' + optional + '" class="moreConsole" src="../Content/images/icons/arrow.png">';
} else if (type == 3) {
strType = 'errorConsole';
iconType = 'errorIcon.png';
}
var iconOutput = '<img class="iconConsole" src="../Content/images/icons/' + iconType + '">';
var dateOutput = '<div class="dateConsole">' + iconOutput + ' ' + actualDate.toLocaleDateString() + ', ' + actualDate.toLocaleTimeString() + ' : </div>';
var consoleOutput = prevContent + '<div class="outputConsole">' + dateOutput + content + moreOutput + '</div>';
$('#userConsole').html(consoleOutput.toString());
var height = $('#userConsole')[0].scrollHeight;
$('#userConsole').scrollTop(height);
//my try to update the tab
var tabStrip = $('#tabConsole'),
selectedIndex = tabStrip.data('kendoTabStrip').select().index(),
clone = original.clone(true);
clone.children('ul')
.children('li')
.eq(selectedIndex)
.addClass('k-state-active')
.end();
tabStrip.replaceWith(clone);
$('#tabConsole').kendoTabStrip({
animation: {
open: {
effects: 'fadeIn'
}
}
});
}
How can I update the contents of the DIV that are inside the TabStrip?
EDIT
It seems Kendo UI renames the DIVs' ids that represent the tabs to tabConsole-1 and tabConsole-2, explaining why the update wasn't working, still there's a lot of strange behavior, I had to specify the height for each DIV so the overflow propety would work, also the images with id viewDetails and class moreConsole when set to position absolute, get rendered outside the DIV that represents the tab, but if I change the position property to relative, the images stay inside the DIV but are displayed not at the end of the DIV like I want to, but relative to the size of the DIV that comes before them.
I'm really confused as to how to set the styles so the contents are displayed properly.

Adding content to a tabStrip can be achieved using:
$(tabConsole.contentElement(idx)).append(newContent)
where:
idx is the tab index,
newContent is what you want to add to the existing content and
tabConsole is the variable set to $("#...").kendoTabStrip(...).data("kendoTabStrip");.
You don't need to create a new tabStrip (in addition you should not re-create KendoUI elements since this is a pretty expensive operation).
About using multiple tags with the same id... you should not use it, use class instead. ids should be unique.
I'm still trying to understand your problem with the styling.

How to create a toggle button that dynamically changes HTML content?

I have been working on this question for several days, and have researched it on SO as well as the web at large and was unable to find material that helped me solve it.
I am trying to create a weather app that can toggle the weather units displayed between Fahrenheit and Celsius. I start by appending the weather in Fahrenheit, and then I have created an event handler that conditionally changes the inner content of the associated element based on whether that element is currently displaying "F" or "C".
As it is, my app successfully loads with the Fahrenheit temperature, and toggles to Celsius on click, but it will not toggle back to Fahrenheit. I assume there is some issue with how the events are registered, but for the life of me I cannot figure it out.
Here is my code:
var fahr = document.createElement("a");
fahr.attr = ("href", "#");
fahr.className = "tempUnit";
fahr.innerHTML = tempf + "°F" + "<br/>";
$("#currentWeather").append(fahr);
var cels = document.createElement("a");
cels.attr = ("href", "#");
cels.className = "tempUnit";
cels.innerHTML = tempc + "°C" + "<br/>";
var units = document.getElementsByClassName("tempUnit");
$(".tempUnit").click(function() {
if (units[0].innerHTML.indexOf("F") != -1) {
$(".tempUnit").replaceWith(cels);
} else {
$(".tempUnit").replaceWith(fahr);
}
})
Thank you so much in advance! Happy to provide additional information if necessary.
Currently what you are using is called a direct binding which will only attach to element that exist on the page at the time your code makes the event binding call.
As you using replaceWith(), existing element is replaced with new element and event handlers are not attached with them.
You need to use Event Delegation using .on() delegated-events approach.
General Syntax
$(parentStaticContainer).on('event','selector',callback_function)
Example, Also use this i.e. current element context and use setAttribute() to update href element
$("#currentWeather").on("click", ".tempUnit", function() {
if (this.innerHTML.indexOf("F") != -1) {
$(this).replaceWith(cels);
}
else {
$(this).replaceWith(fahr);
}
})
var tempf = 212;
var tempc = 100;
var fahr = document.createElement("a");
fahr.setAttribute("href", "#");
fahr.className = "tempUnit";
fahr.innerHTML = tempf + "°F" + "<br/>";
$("#currentWeather").append(fahr);
var cels = document.createElement("a");
cels.setAttribute("href", "#");
cels.className = "tempUnit";
cels.innerHTML = tempc + "°C" + "<br/>";
$("#currentWeather").on("click", ".tempUnit", function() {
if (this.innerHTML.indexOf("F") != -1) {
$(this).replaceWith(cels);
} else {
$(this).replaceWith(fahr);
}
})

extract div as HTML including CSS classes

I am trying to create a general function that will extract a div content (with nested elements) and save it locally in an HTML file.
Basically I get the div innerHTML, wrap it in html/head/body tags and then save it:
function div2html() {
var inner=document.getElementById("div2save").innerHTML;
var html="<html><head></head><body>"+inner+"</body></html>";
saveTextAsFile("div2html.html", html);
}
See a working version here: jsfiddle
However I am not sure how to handle classes. As you can see the class in the sample (bigbold) is not embedded in the new HTML. I need some way to get all the classes used in the div and then add them (or the computed styles ?) to the html I generate .. is this possible ? is there any other way around it ?
Try including style element .outerHTML within saved html
function div2html() {
var inner=document.getElementById("div2save").innerHTML;
var style = document.getElementsByTagName("style")[0].outerHTML;
var html="<html><head>"+style+"</head><body>"+inner+"</body></html>";
saveTextAsFile("div2html.html", html);
}
jsfiddle http://jsfiddle.net/fb6s763w/1/
Alternatively, using window.getComputedStyle() to select only css of #div2save child node
function div2html() {
var inner = document.getElementById("div2save");
var style = window.getComputedStyle(inner.children[0]).cssText;
var html = "<html><head><style>"
+ "." + inner.children[0].className
+ "{" + style + "}"
+ "</style></head><body>"
+ inner.innerHTML + "</body></html>";
saveTextAsFile("div2html.html", html);
}
jsfiddle http://jsfiddle.net/fb6s763w/2/
Looks like this might be able to help you out:
https://github.com/Automattic/juice
If the CSS of the page is not big, a simple solution is to include it all in the saved html as suggested by guest271314 above with
var style = document.getElementsByTagName("style")[0].outerHTML;
see jsfiddle
A more comprehensive solution extracts the classes from the div and then adds only the rules of those classes to the div (Using code from How do you read CSS rule values with JavaScript?)
function div2html(divId) {
var html = document.getElementById(divId).innerHTML;
// get all css classes in html
var cssClasses = [];
var classRegexp = /class=['"](.*?)['"]/g;
var m;
while ((m = classRegexp.exec(html))) cssClasses = cssClasses.concat(cssClasses, m[1].split(" "));
// filter non unique or empty cssClasses
cssClasses = cssClasses.filter(function (item, pos, self) {
return item && self.indexOf(item) == pos;
});
// get html of classes
var cssHtml = '';
for (var i = 0; i < cssClasses.length; i++) cssHtml += getRule('.' + cssClasses[i]);
// assemble html
var html = "<html><head><style>" + cssHtml + "</style></head><body>" + html + "</body></html>";
console.log(html);
saveTextAsFile("div2html.html", html);
}

JS element creation / removal on Mouseover / out conundrum

JS only. On mouseover I'm calling a function I made that creates a div element with an image inside.
I pass (this) as a parameter to the function. The function works and onmouseover it creates a child element and I can click it. However, If I add on mouse out of the div to remove itself, it will only do so if I hovered over it. If I didn't, the div stays and on next hover it adds another one. If I add on mouse out of the parent element to remove the div, I cannot get to hover over the child div, cause as soon as I leave the parent, the child div is removed. The parent element is an (a href) inside a "TD" in a table. The code goes like this:
<script type="text/javascript">
function PopPanel(ownerElem) {
var myParent = ownerElem.parentNode;
var popanel = document.createElement("div");
popanel.className = "divPopPanel";
popanel.setAttribute("display", "block")
var phoneimg = document.createElement("img");
phoneimg.src = '/images/ImageAdditions/Phone.png';
phoneimg.className = "popupPhone";
popanel.appendChild(phoneimg);
phoneimg.onclick = function () {
try {
location.replace("Mylauncher:\\\\nas\\vol5\\SYSTEM\\ITR\\Scripts\\SomeProgram.exe" + " " + ownerElem.innerText);
}
catch (err) {
}
};
myParent.appendChild(popanel);
popanel.onmouseout = function (e) { this.parentNode.removeChild(this) }; //this removes itself on mouseout.
myParent.onmouseout = function (e) { popanel.parentNode.removeChild(popanel) }; // this removes the child element of the parent (which is the same element as above) on mouse out.
};
Well, after a long and miserable trial and error session, I've figured this out.
First I've modified the code that generates and populates the gridview with data, like this:
VB.net
dt.Columns.Add("InternalPhoneDialer", Type.GetType("System.String"))
Dim rn As New Random
Dim randNum As Integer = rn.Next(12, 428)
Dim internalphone As String = dr("InternalPhone").ToString
If internalphone.Contains(" ") Then
internalphone = internalphone.Substring(0, internalphone.IndexOf(" "))
internalphone = internalphone & randNum.ToString()
Else
internalphone = internalphone & randNum.ToString()
End If
//Substitute the current column with the newly created one above
dr("InternalPhoneDialer") = "<div id='popPanelWrapper" & internalphone & "' onmouseover='PopPanel(" & "popPanelWrapper" & internalphone & ");' onmouseleave='PopPanelClose(" & "popPanelWrapper" & internalphone & ");'> <a class='popPanelLink' href='javascript:void(0);' >" & dr("InternalPhone") & "</a> </div>"
I have made sure that I concatenate a unique id to each div in case the phone number is the same for another column (where I implement the same solution). So I added the column inner content + a random number and concatenated it to the DIV name.
Then, on client side I've modified my script like this:
JavaScript
<script type="text/javascript">
function PopPanel(ownerElem) {
var myParent = ownerElem;
var phoneimgexist = !!document.getElementById("popupPhone");
if (phoneimgexist) {
return
} else {
var phoneimg = document.createElement("img");
phoneimg.src = '/_layouts/15/images/ImageAdditions/Phone.png';
phoneimg.id = "popupPhone";
phoneimg.setAttribute("display", "block")
myParent.appendChild(phoneimg);
}
phoneimg.onclick = function () {
try {
location.replace("launcher:\\\\drive01\\vol1\\SYSTEM\\ITR\\Scripts\\Jabber.exe" + " " + ownerElem.innerText);
}
catch (err) {
}
};
};
function PopPanelClose(ownerElem) {
var myParent = ownerElem;
var phoneimg = document.getElementById("popupPhone");
var phoneimgexist = !!document.getElementById("popupPhone");
if (phoneimgexist) {
phoneimg.parentNode.removeChild(phoneimg);
} else {
return
}
};
Now, on mouse over a GridVew cell that contains a phone number I get an icon. By clicking it I can call the number.
In my opinion this solution is much better suited for the task, instead of creating a hidden div with image and data for every row in what could be thousands of entries in the GridView.
This no doubt saves a lot of resources.

mouseover and mouseout events not firing using pure js

I have a setup where i am trying to assign a mouseover and mouseout event on a div, but they dont appear to be firing. Right now i just have it trying to console.logthe mouseout event and add classes to the body as well for the mouseover event.
I have trying using .addEventListener('mouseover', function(){}) instead of .onmouseover to no avail. I have also tried mouseenter and mouseleave but these are IE only events.
I need to use pure Javascript rather than any 3rd party library, this also needs to work in IE8+.

here's a JSFiddle
SOLUTION UPDATE:
So it appears that the reason this was breaking was because of the way that I was inserting the modal elements using document.body.innerHTML += . Which I think must read all the innerHTML with the newly appended content. As a better solution I used this:
function addModal (){
var modalBack = document.createElement("div");
modalBack.setAttribute("class", "exp_modal_back");
document.getElementsByTagName("body")[0].appendChild(modalBack);
var modalCont = document.createElement("div");
modalCont.setAttribute("class", "exp_modal");
document.getElementsByTagName("body")[0].appendChild(modalCont);
}
updated JSFiddle
Your problem is not with how you are using the event handlers. The problem is being caused by the "addModal" function called after the "processExpandable" function. I don't understand what you are trying to accomplish so I can't help you there, but it is a start.
Also, I think you have a problem in the "launchModal" function. Do you really want to keep adding and adding values to the class attribute of the body?
You can try this way :
<div style=" height: 200px; width:200px; background-color: black;"
onmouseover="displayElement('myDiv');"
onmouseout="hideElement('myDiv');">
<div id="myDiv" class="of_expandable" data-channel="2935725596001" data-muted="1" data-skin="dark" style="width:100%; height:100%;display: none; background-color:green;">Content</div>
</div>

Calling Jquery accordion on google maps only runs once

So I've created a google maps page with a bunch of markers generated from XML. The idea is that when you click on a marker a div will be generated that displays events information related to that marker. This all works fine but what I'm struggling with is now trying to attach an accordion to the events information. The code I have so far will show an accordion on the first marker you click on (can be any one and it returns the correct info, shows the div and has an accordion) but not on any subsequent marker clicks, even the same one for a second click.
I'm sure this must be a simple fix but I've tried a few variations (there are three attempts at the accordion that I have left in to show the different versions) and I am getting the same results.
Here is the code that binds the events to the markers as a google event listener..
function bindEvents(marker, id, venueName, website){
google.maps.event.addListener(marker, 'click', function(){
// TARGET and show eventsFeed on click
$('#eventsFeed').show(222);
var eventsList = document.getElementById('eventsList');
// ADDS styles to the events feed divs when created
// DECLARED here for the inclusion of the venueName & website as feedhead
// even when no events are present
var venueNameDiv = "<div class='venueNameFeed'>";
var webSiteDiv = "<a target='_blank' class='websiteInFeed' href='http://"+website+"'><span class='fa fa-home'></span></a>";
var titleInFeed = "<div class='"+id+" eventTitleFeed'>";
var accordDataWrap = "<h2 class='accordWrap>";
var eventInFeed = "<div class='eventDescFeed'>";
var dateInFeed = '<div class="eventDateFeed">';
var priceInFeed = "<div class='eventPriceFeed'>";
// CLOSE the divs after each entry
var divBrk = "</div>";
var closeAccordDataWrap = "</h2>";
var feedHead = venueNameDiv + venueName + divBrk;
// EMPTY array to line up matched events in
var eventsLine = [];
// CYCLE through eventsArray
for (var key in eventsArray){
var eventLoop = eventsArray[key];
// MATCH id to venue_id
var venue_id = eventLoop.venue_id;
if (venue_id == id){
// ONLY show events from todays date onward
var now = new Date();
var date = new Date(eventLoop.eventDATE);
// SET hours to 0 to ignore time part (always as 01:00:00 for event date?)
now.setHours(0,0,0,0);
if (date >= now){
//ADD all matched events to eventsLine array
eventsLine.push(titleInFeed + eventLoop.eventTitle + divBrk +
accordDataWrap + eventInFeed + eventLoop.event + divBrk +
dateInFeed + formatDate(eventLoop.eventDATE) + divBrk +
priceInFeed + "£" + eventLoop.price + divBrk + closeAccordDataWrap);
}
}
}
// TURNS the array into a string and replaces those damned, infernal commas!!
var outputString = eventsLine.toString().replace(/>,/g, '>');
// PUT the compiled array into the eventsFeed div (with venueName as title)
if (website==""){
eventsList.innerHTML = feedHead + outputString;
} else {
eventsList.innerHTML = feedHead + webSiteDiv + outputString;
}
// ADD the accordion
$(document).on('click', marker, function(){
$(eventsList).accordion({
header: "div."+id,
icons: null
})
})
// OR
$(eventsList).each(function(){
$(eventsList).accordion({
header: "div."+id,
icons: null
});
});
// OR
accordion(eventsList, id);
});
}
This third option calls a separate function which is defined as;
function accordion(placement,id){
$(placement).accordion({
header: "div."+id,
icons: null
});
}
As you can probably tell I'm pretty new to all of this so any help or advice with anything would be greatly appreciated! :)
Can you replace this code:
$(eventsList).each(function(){
$(eventsList).accordion({
header: "div."+id,
icons: null
});
});
with this code:
$(eventsList).each(function(){
$(this).accordion({
header: "div."+id,
icons: null
});
});
and try. Also it will be better if you can Create a fiddle for your code.
