I am trying to script a textarea preview (like stackoverflow) that shows in a div automatically. I have created a script, but it does not seem to be working. If anybody could help me out with the script in HTML and JavaScript I'll be greatfull.
Like this in the picture:

Your question is vague, but maybe a few pointers will help.
You'll want to update your target div every time the user types a character. This is the onkeyup handler (or onkeydown, depending on your intended UX - probably the former).
Do you want to retain any HTML your user enters in the text area? If so, you'll want to update the innerHTML property of your target div. If you want to update just the text, change the innerText property.
A quick and dirty example using jQuery:
$("textarea#my_input").bind('keyup', function() {
$("div#target").text($(this).val());
}
As requested, in vanilla JavaScript:
document.getElementById("my_input").onkeyup = function() {
document.getElementById("target").innerText = this.value;
}
If you want to show whatever is typed in the textarea in the div below it.
You can work with Jquery .keypress() function.
Sample Fiddle.
This is just a starting point.You can alter it to suit your requirements.
For further reference Jquery .keypress()

I'm looking for a solution that will allow me to display a div when I click on a single link (which will change the way css style) with variable content (eg a sub-div with service1, service2, service3 ). This div will be displayed also propose several offers that will only display the div payment when one of these offers will be selected.
It's maybe hard to explain (i'm not english so sorry for really noob level), so maybe with this image you will "understand" a little bit more:

I confess to being a bit lost with JavaScript for this kind of thing. I know it's probably achievable, but how? :-(
Thank you for your help folks!
If you want to go the way with altering CSS with javascript, assuming you are not creating the variable content on the fly, have the divs css for display set to none.
#divID {
display = none;
}
Then set an event listener on your link to change the display style to block.
document.getElementById("linkID").addEventListener("click", function() {
document.getElementById("divID").style.display = "block";
}
Ok so I created a crude representation of what you asked without much effects. But the fiddle I created completely functions as you intended. If you click buttons on div 1 the content of div 2 gets updated. If you click anything on div2 the information is displayed in div3. Here is the example: Working Example
window.function1 = function(){
var edits = document.getElementById('2');
edits.style.background="aliceblue";
}
//SAMPLE CODE TO EDIT ANY ELEMENT BY REFERRING BY ID. CALL SUCH FUNCTION ONCLICK
Please check the example to understand it fully.
I have a CKeditor that loads text which includes html text as well. The html text has a css class assigned to certain span text areas. When the user does a mouse-over or mouse-click on text surrounded by a span with a particular class in the CKEditor textbox, I want to fire the mouse-over event or click event.
Here is the text that I programmatically load into the CKEditor
var editorHtml = '<span class="noedit">no edit text</span> edit this';
and I am trying to catch the events via this code.
$(document).ready(function () {
$('.noedit').mouseover(function () {
alert('hello');
});
});
It doesn't seem to be working. What am I doing wrong? Is this even possible to do?
Try to use event delegation here since your span is probably added dynamically by CKEditor here:
$(document).ready(function () {
$(document).on('mouseover','.noedit', function() {
alert('hello');
});
});
What is the this question really about? Your question reads: "get css class of html text in CKEditor". But I guess you want the class="noedit" element not editable. Maybe block it with a popup saying: "No editing allowed?"
The best way to add non editiable content is with widgets. This post explains what widgets are. If you follow the tutorial, you will be able to create a template for a simple box with two editable fields. You want NOT editable? It's in tutorial part one:
Please note that only elements defined in CKEDITOR.dtd.$editable can
be converted into editable widget elements.
By not specifying editable your widget will not be editable.
I do not know exactly what you try to achieve. But it seems that <span class="noedit">no edit text</span> should be a widget. You can still insert your widget with var editorHtml but you could also use a button.
I hope my answer is useful! Enjoy.
Sorry if the question was misleading, I couldn't find a better way to describe my problem. Anyway, here goes:
Suppose I had a button start that initially displays a string for me. Said string (let's call it stringA) is output through jQuery like this:
$(".start").click(function() {
$(".startButton").hide('slow', function() {
$("#table1").html(stringA);
});
});
Alright. Cool. That worked without a hitch. Now inside stringA I have multiple
<span class="optButton">this is a button</span> buttons. I have another onClick handler for my optButton button, and it goes like this:
$(".optButton").click(function() {
alert("Testing");
$("#table1").html(stringB);
});
Needless to say, clicking on optButton is supposed to replace the contents of #table1 with stringB. However, when I tried it, it doesn't work. I tried adding alert() to test and see if jQuery managed to select optButton, but it seems that it didn't because I get no popup from the alert() function.
My theory is that since optButton was not part of the original HTML and is within a string stringA, jQuery is unable to select optButton as a result. If this is true, is there a workaround to this issue? If it is not, what is the actual cause of the problem here?
You need to use event delegation since your span element has been dynamically added to the DOM:
$('#table1').on('click', '.optButton', function() {
alert("Testing");
$("#table1").html(stringB);
});
This technique will helps you to attach click handler to these newly created span elements.
I would like to know if there is a jquery function that would let me create a clear icon floating next to input text inside a search box like this:
I could not find any example anywhere, I doubt that this is possible but a confirmation would be appreciated.
$('#input').keyup(function(){
$('<span id="width">').append( $(this).val() ).appendTo('body');
var width = $('#width').width() + 2;
$('#width').remove();
// variable "width" is now the margin required to be given from left to be next to the input's context
console.log(width);
});
This script creates a temporary <span> tag next to your <input> tag, with the same content as your <input> tag, therefor having the <span> tag the same width as your content.
See it in action here: http://jsfiddle.net/Wa7Lf/
The only thing you are going to have to do on your own is hovering it above the input field and adding your own icon, but that shouldn't be that hard.
I know it isn't perfect, but it should help you forward.
I think that is not really what you want but should go in the right direction.
http://demos.kendoui.com/web/multiselect/index.html
An "jQuery function" is not there I think. Eventually if you search, you will find an jQuery plugin for this. I don´t know. Take a look at jQuery UI or bootstrap or some other framework out there. Or take a look at the source from the kendo ui multiselect and build you own ;-)
May not worth adding another library just for this UI element. The other option besides the proposed jQuery UI/bootstrap/kendoui would be to add in an image with display: inline; and a small bit of margin to the left of the 'x' image.
In theory you could also do the whole element in css, but that's likely not worthwhile in your case.
I'm trying to enable a button when the text in the jWYSIWYG textarea is changed. As far as i know, the jWYSIWYG when invoked, removes the textarea and places an iframe in its place, so $("#my-textarea-id") selector wont return any object. These are the attempts i made, all of them failed:
ATTEMPT 1:
as shown here this code should work, but it does not :(
$("#my-textarea-id").wysiwyg({
event:{
keyup: function(e){
$("#my-button").attr("disabled",false);
}
}
});
ATTEMPT 2:
in following attempts i'm initalizating the jWYSIWYG textareas from a diferent script that applies the .wysiwyg(...) function to all .RTF elements in the page (my textarea has this class).
The new frame that jWYSIWYG places has [old_textarea_id]-wysiwyg-iframe as ID, so i tried this:
$("#my-textarea-id-wysiwyg-iframe").keyup(function(){
$("#my-button").attr('disabled',false);
});
but failed again.
ATTEMPT 3:
The iframe part containing the text of the textarea has the .wysiwyg class. My last attempt was this:
$(".wysiwyg").keyup(function(){
$("#my-button").attr('disabled',false);
});
I have no idea how to handle the events over the jWYSIWYG elements so i ask for your help. Thank you!
this solved my problem
Adding event handler to an iframe using JQuery
jWYSIWYG replaces the textarea for an iframe. The below question's answer tells the appropiate way to bind events to the iframes and this way one can handle events of the RTF online editor.
i think the question can be useful for people so i'll not delete it for now.
