I have a problem below is my code. i have use toggleClass and passed a css class in it. Now if i use without live() method it is working fine. But if i use with live() method it is not working i am stuck into this problem.
//Without live() method and it is working fine
$('#shownColumnsDiv tbody tr').click(function () {
globalMove = $(this);
globalArray.push(globalMove);
index = $('#shownColumnsDiv tbody tr').index(this);
alert(index);
globalMove.toggleClass('highlight');
});
//With live() method it is not working fine
$('#shownColumnsDiv tbody tr').live("click", function(){
globalMove = $(this);
globalArray.push(globalMove);
index = $('#shownColumnsDiv tbody tr').index(this);
alert(index);
globalMove.toggleClass('highlight');
});
//this is a css portion
.highlight {
background-color: #0078ae;
color: white;
}
Try:
globalMove.toggleClass('highlight');
globalMove is already a jQuery object, because you stored $(this) in it, why would you want to generate a jQuery object of the jQuery object by writing $(globalMove)?
Looks like it's working fine for me?
use .on instead of live.
it is now no longer recommeded.
Now with .live() being deprecated in jQuery version 1.7 and removed in version 1.9, we need to use the .on() method. Here's an equivalent example using the .on() method:
$(document).on('click', 'button', doSomething);
function doSomething() {
// do something
}

I have a page with multiple textareas that use TinyMCE to be able to display WYSIWYG content. This works fine but I need to set a specific textarea content from a function. I tried this approach...
<script>
function addText() {
var html = "<b>hello world</b>";
tinymce.get('#myFirstTextArea').setContent(html);
}
</script>
But when I do that I get a "Cannot read properties of null (reading 'setContent')" Error. What am I doing wrong here?
I use TinyMCE ver 6
Most likely you have a timing issue in your JavaScript. You cannot make a get() call until after TinyMCE is fully initialized.
TinyMCE has an event that gets called once the editor is fully initialized. You can put this in your TinyMCE init. For example:
tinymce.init({
...
setup: function (editor) {
editor.on('init', function (e) {
editor.setContent('<p>This is the content in TinyMCE!</p>');
});
}
...
});
I am a UI person and very new to ionic framework.. I wanted to add search feature in my android app built using Ionic framework. After a research i found that I will need to use this plugin https://github.com/djett41/ionic-filter-bar. but there is no detail documentation available. Can anyone please guide how to use this plugin working. I have made all setup but stuck with actual code.
First of all you must install the plugin. You can use bower for that:
bower install ionic-filter-bar --save
and it will copy all the javascript and css needed in the lib folder inside www.
Then you must add the references to the css to your index.html:
<link href="lib/ionic-filter-bar/dist/ionic.filter.bar.css" rel="stylesheet">
same thing for the javascript:
<script src="lib/ionic-filter-bar/dist/ionic.filter.bar.js"></script>
You have to inject the module jett.ionic.filter.bar you your main module:
var app = angular.module('app', [
'ionic',
'jett.ionic.filter.bar'
]);
and you must reference the service $ionicFilterBar in your controller:
angular.module('app')
.controller('home', function($scope, $ionicFilterBar){
});
Now you can start using it.
In my sample I want to trigger the search-box when the user clicks/taps on a icon in the header. I would add this HTML to the view:
<ion-nav-buttons side="secondary">
<button class="button button-icon icon ion-ios-search-strong" ng-click="showFilterBar()">
</button>
</ion-nav-buttons>
The action trigger an event in my controller showFilterBar:
$scope.showFilterBar = function () {
var filterBarInstance = $ionicFilterBar.show({
cancelText: "<i class='ion-ios-close-outline'></i>",
items: $scope.places,
update: function (filteredItems, filterText) {
$scope.places = filteredItems;
}
});
};
which creates the $ionicFilterBar and shows it.
As you can see here I am using an array of objects $scope.places
$scope.places = [{name:'New York'}, {name: 'London'}, {name: 'Milan'}, {name:'Paris'}];
which I have linked to the items member of my $ionicFilterBar. The update method will give me in filteredItems the items (places) filtered.
You can play with this plunker.
Another option is to use the plugin to actually fetch some data remotely through $http.
If we want to achieve this we can use the update function again.
Now we don't need to bind the items to our array of objects cause we won't need the filtered elements.
We will use the filterText to perform some action:
$scope.showFilterBar = function () {
var filterBarInstance = $ionicFilterBar.show({
cancelText: "<i class='ion-ios-close-outline'></i>",
// items: $scope.places,
update: function (filteredItems, filterText) {
if (filterText) {
console.log(filterText);
$scope.fetchPlaces(filterText);
}
}
});
};
We will call another function which will, maybe, call $http and return some data which we can bind to our array of objects:
$scope.fetchPlaces = function(searchText)
{
$scope.places = <result of $http call>;
}
Another plunker here.
PS:
If you want to configure it using some sort of customization you must do it in your configuration using the provider $ionicFilterBarConfigProvider:
angular.module('app')
.config(function($ionicFilterBarConfigProvider){
$ionicFilterBarConfigProvider.clear('ion-ios-close-empty');
})
PPS:
In my plunker I've included the css and the script directly copying it from the source.
UPDATE:
Someone asked not to replace the list with the updated one.
My cheap and dirty solution is to check if the filterText contains some values. If it's empty (no searches) we go throught each element an set a property found = false otherwise we compare the places array we the filteredItems array.
Matching elements will be marked as found.
function allNotFound(filteredItems) {
angular.forEach($scope.places, function(item){
item.found = false;
});
}
function matchingItems(filteredItems) {
angular.forEach($scope.places, function(item){
var found = $filter('filter')(filteredItems, {name: item.name});
if (found && found.length > 0) {
console.log('found', item.name);
item.found = true;
} else {
item.found = false;
console.log('not found', item.name);
}
});
and now we can integrate the filter bar this way:
$scope.showFilterBar = function () {
var filterBarInstance = $ionicFilterBar.show({
cancelText: "<i class='ion-ios-close-outline'></i>",
items: $scope.places,
update: function (filteredItems, filterText) {
if (!filterText) {
allNotFound();
} else {
matchingItems(filteredItems);
}
}
});
};
We can use the found attribute of the object to change the style of the element.
As always, a Plunker to show how it works.
Ionic uses Angular, and Angular include an atributte filter very useful. Look this: https://docs.angularjs.org/api/ng/filter/filter and the example there. Regards
I can't find anything about this on the web. Is there a way to set the default view of Summernote (WYSIWYG jQuery text editor) to be the code/html view. I want to see directly the HTML code when landing on the form page.
Thank you
You can simulate a click on the codeview button (after summernote initialization), it works for me :
$('.summernote').summernote({
oninit: function() {
$("div.note-editor button[data-event='codeview']").click();
}
});
From Summernote documentation:
After v0.7.0, every callbacks should be wrapped by callbacks object.
So, in order to work, the js should be like this:
$('.summernote_editor').summernote({
callbacks: {
onInit: function() {
$("div.note-editor button.btn-codeview").click();
}
}
});
Not very elegant and I don't know if there is a proper way to do it but give this a try if you like:
From what I can tell, and I didn't look very hard, the codeview button does this:
adds a 'codeview' class to div.note-editor
disables all the buttons
adds an 'active' class to the codeview button elemment.
You may discover that it does other things as well but this should put you on a workable path.
$('div.note-editor').addClass('codeview');
$('div.note-editor.codeview button').addClass('disabled');
$("div.note-editor.codeview button[data-event='codeview']").removeClass('disabled').addClass('active');
Well, you can use the init callback.
$('.summernote').on('summernote.init', function () {
$('.summernote').summernote('codeview.activate');
}).summernote({
height: 300,
placeholder: 'Paste content here...',
codemirror: {
theme: 'monokai'
}
});
I am using the Onsen framework with jQuery and jQuery mobile, it appears that there is no way to catch the event that fires once the new page is loaded.
My current code, which executes in the index.html file (the master page)
<script src="scripts/jQuery.js"></script>
<script src="scripts/jquery.mobile.custom.min.js"></script>
<script src="scripts/app.js"></script>
<script>
ons.bootstrap();
ons.ready(function() {
$(document.body).on('pageinit', '#recentPage', function() {
initRecentPage();
});
});
in app.js is the following code
function initRecentPage() {
$("#yourReports").on("tap", ".showReport", recentShowReport);
var content = document.getElementById("yourReports");
ons.compile(content);
}
and the HTML:
<ons-page id="recentPage">
<ons-toolbar id="myToolbar">
<div id="toolBarTitle" class="center">Recent Checks</div>
<div class="right">
<ons-toolbar-button ng-click="mySlidingMenu.toggleMenu()">
<ons-icon icon="bars"></ons-icon>
</ons-toolbar-button>
</div>
</ons-toolbar>
<ons-scroller>
<h3 class="headingTitle"> Checks</h3>
<div id="Free" class="tabArea">
<ons-list id="yourReports">
</ons-list>
<ons-button id="clearFreeRecentButton">
<span id="clearRecentText" class="bold">Clear Recent Checks</span>
</ons-button>
</div>
</ons-scroller>
</ons-page>
in this instance the variable 'content' is always null. I've debuged significantly, and the element I am trying to get is not present when this event fires. It is loaded later.
So, the question is, how do I ensure that all of the content is present before using a selector. It feels like this is an onsen specific issue.
In the end I could only find one reliable way of making this work.
Essentially I had to wait, using setTimeout 300 milliseconds for the DOM elements to be ready. It feels like a hack, but honestly there is no other reliable way of making this behave. The app is in the app store and works well, so even though it seems like a hack, it works:
$(document).on('pageinit', '#homePage', function() {
initHomePage();
});
function initHomePage() {
setTimeout(function() {
setUpHomePage();
}, 300);
}
Move your $(document.body).on('pageinit', '#recentPage', function() { outside of ons.ready block.
JS
ons.bootstrap();
ons.ready(function() {
console.log("ready");
});
$(document.body).on('pageinit', '#recentPage', function() {
initRecentPage();
});
function initRecentPage() {
//$("#yourReports").on("tap", ".showReport", recentShowReport);
var content = document.getElementById("yourReports");
alert(content)
ons.compile(content);
}
I commented out a line because I do not have access to that "recentShowReport"
You can see how it works here: 'http://codepen.io/vnguyen972/pen/xCqDe'
The alert will show that 'content' is not NULL.
Hope this helps.
I'm trying to start a jquery ui resizable instance, but using a selector added to the DOM by jquery itself. This is a basic example of my script:
HTML:
<div class='lyr'></div>
jQuery:
// Add class
$('lyr').addClass('fixed');
// Resizable
$('.fixed').resizable({
aspectRatio: true,
handles: 'all'
});
I've thought about using something along the lines of live() or bind() but I have no event to bind to. Any help appreciated.
I have used the LiveQuery plugin - http://brandonaaron.net/code/livequery/docs in the past to be able to target elements added to the dom, like in your case.
If I've got this right, you want anything on the page which has the class "fixed" to be resizable, even if the class is added after the page has loaded? You're right that live, bind and delegate won't help here.
I can think of two possibilities, neither lovely.
First, set up a live "mouseenter" event which will make the element resizable if it wasn't before:
$(body).delegate(".fixed", "mouseenter", function(ev) {
var target = $(ev.target);
if (target.data("resizable")) return;
target.resizable({
aspectRatio: true,
handles: 'all'
});
})
This gets us round the problem of having no event to bind to.
Alternatively, you could monkeypatch jQuery.fn.addClass:
var classRe = new RegExp(c + className + \b);
._addClass = jQuery.fn.addClass;
jQuery.fn.addClass = function(className) {
if (classRe.test(classname)) {
if (this.data("resizable")) return;
this.resizable({
aspectRatio: true,
handles: 'all'
});
}
jQuery.fn._addClass.apply(this, arguments);
}
Of course this will only work if the class is added through the addClass method.
Also in your example,
$('lyr').addClass('fixed');
Should probably be:
$('.lyr').addClass('fixed');
