I'm trying create a textbox and a draggable button.
At the moment when I click on the button a certain text is added to the begging of the textbox (JavaScript and HTML).
I want to add an option to drag the button into the textbox which will cause the same text from when I click on the button to be added into the textbox.
If it possible I also would like to choose where to add this text. I.e if I drag the button and drag in middle of a sentence in the textbox, it will add the text to the middle of the sentence where I dropped the text and not at the start of the textbox.
Thanks from advance.
Edit:
Here is part of the code i already did, sorry it a little messy (for what i'm doing i need all to put all in string).
var emoticon1 = "<input title='curious' onclick='add_tag("+'"curious"'+");' type='image' id='cur' src='/content/modules/dev/emoticons/curious.png' style='height:48px;width:48px;' />";
var emoticon2 = "<input title='confused' onclick='add_tag("+'"confused"'+");' type='image' id='con' src='/content/modules/dev/emoticons/confused.png' style='height:48px;width:48px;' />";
var emoticon3 = "<input title='helpful' onclick='add_tag("+'"helpful"'+");' type='image' id='help' src='/content/modules/dev/emoticons/helpful.png' style='height:48px;width:48px;' />";
var emoticon4 = "<input title='intersted' onclick='add_tag("+'"intersted"'+");' type='image' id='inte' src='/content/modules/dev/emoticons/interested.png' style='height:48px;width:48px;' />";
var tmp = "var txt=document.getElementById('commentTB').value;txt='#' + type + ' ' + txt ;document.getElementById('commentTB').value=txt;";
var fun = "<script> function add_tag(type) {"+tmp+"} </script>";
var emoticonsList = fun + emoticon1 + emoticon2 + emoticon3 + emoticon4;
The result at the moment:
how the current code looks
At the moment (I work in ubuntu if it matters), if run it in chrome, it let me drag the buttons (the pictures) and put them in the text, but it put the "src" in the textbox instead of the text i want. On the other hand, in firefox the buttons can't be dragged, even if add draggable="true".
You can do it with Drag & Drop-API.
document.addEventListener('dragstart', function (event) {
event.dataTransfer.setData('Text', event.target.innerHTML);
});
#buttons p {
appearance:button;
-moz-appearance:button;
-webkit-appearance:button;
display: inline-block;
padding: 2px 5px;
}
<div id="buttons">
<p draggable="true" id="1">This</p>
<p draggable="true" id="2">is</p>
<p draggable="true" id="3">a</p>
<p draggable="true" id="4">simple</p>
<p draggable="true" id="5">Drag'n'Drop-Test</p>
</div>
<textarea></textarea>
Tested in Chrome & Firefox.
Not sure what you've done so far so it's difficult to help but it sounds like jQuery UI could be useful here

I got a problem in updating the value within <textarea> tags. The procedure is like this, there is an initial value inside textarea, then the user changes it. If I want to use a js script (implemented by a button) to modify the value further, it does not work at all. However, if we do nothing on the textarea, the button works perfectly. So weird to me. Could anyone shed any light on this? The code is posted below.
$(document).ready(function() {
$("#mybutton").click(function() {
var mystring = "The previous textarea value is <br><em>" + $("#myarea").val() + "</em>";
$("#myarea").html("Star wars"); // this line doesn't work after editting the textarea but works if you do not edit anything, why?
$("#placeholder").html(mystring);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<body>
<div>Input whatever you want</div>
<textarea id="myarea" style="width: 300px; height: 70px">Initial text</textarea>
<div>
<button id="mybutton">Click after editing</button>
<br> The button is supposed to change the text to <em>Star wars</em>.
</div>
<div id="placeholder"></div>
</body>
$(document).ready(function() {
$("#mybutton").click(function() {
var mystring = "The previous textarea value is <br><em>" + $("#myarea").val() + "</em>";
$("#myarea").val("Star wars"); //The changes have to be made on this line
$("#placeholder").html(mystring);
});
});
Inorder to change the value of textarea use val() , instead of html().
Well, as I was searching on the internet for some basic codes to examine - I found this one. A simple code which is supposed to copy the selected text. As i am a complete newbie in JS, I check the meaning of the methods that I didn't understand - and rewrited the code, as i make a few adjustments.
And still the code is not working and If someone can explain - this part ""copyit(this.form.select1)"" - Even though I kind of understand "this" - i am not able to understand what is doind here
function copyit(theField) {
var selectedText = document.getSelection();
if (selectedText.type == 'Text') {
var newRange = selectedText.createRange();
theField.focus();
theField.value = newRange.text;
} else {
alert('select a text in the page and then press this button');
}
}
</script>
<form name="it">
<div align="center">
<input onclick="copyit(this.form.select1)" type="button" value="Press to copy the highlighted text" name="btnCopy">
<p>
<textarea name="select1" rows="4" cols="45"></textarea>
</div>
</form>
This is the original code - and it is not working either
<SCRIPT LANGUAGE="JavaScript">
function copyit(theField) {
var selectedText = document.selection;
if (selectedText.type == 'Text') {
var newRange = selectedText.createRange();
theField.focus();
theField.value = newRange.text;
} else {
alert('select a text in the page and then press this button');
}
}
</script>
And in the body of your web page, add the following where you want the text to appear:
<form name="it">
<div align="center">
<input onclick="copyit(this.form.select1)" type="button" value="Press to copy the highlighted text" name="btnCopy">
<p>
<textarea name="select1" rows="4" cols="45"></textarea>
</div>
</form>
onclick="copyit(this.form.select1)"
executes the copyit() function and passes a variable which is later named theField. The variable that is passed is this.form.select1 which is a textarea with ID select1 which is located in the same form as the input you're clicking hence the this.form.
As to why your code isn't working - you should include here the original code before your adjustments. You probably deleted/changed something you shouldn't have.
I'm not sure what you're asking. Are you asking to, when someone clicks on any button/div, it copies a text you want for his clipboard? If no, ignore my comment, if yes, i'll explain:
First place, where should an user click?
<a class="btn" CopydivFunction(#text)">CLICK ME TO Hello.</a>
Now, add the function with JS.
function copyToClipboard(element) {
var $temp = $("<input>");
$("body").append($temp);
$temp.val($(element).text()).select();
document.execCommand("copy");
$temp.remove();
}
Now, place the text you want somebody to copy (hide it):
<h1 id="text" class="hidden">some text. This part won't be seen because of the hidden class, and this is the text that will be copied to your clipboard.</h1>
Place display:none on css:
#text{
display:none;
}
I think you have to add that, so nobody sees it.
And that should be it, click the <a> and you get the text in the h1#text
<div class="editable" contenteditable="true"></div>
<textarea name="markdown" class="markdown" /></textarea>//display none
new MediumEditor('.editable', {
extensions: {
markdown: new MeMarkdown(function (md) {
document.querySelector(".markdown").textContent = md;
}),
img: new imgButton()
}
$('.editable').append("<img src='abc' />");
I have a div use medium-editor & medium-editor markdown
when user type inside of .editable, textarea will sync.
I also have a button click, it will append an image into .editable
my problem is markdown only update when .editable keypress
so if I append text, textarea wont sync, unless I press any key inside of .editable again
anyone know how to tell markdown to update after append image
try this
function updateTextArea(index,editable){
var textarea = editable.parentNode.querySelector('textarea[medium-editor-textarea-id="' + editable.getAttribute('medium-editor-textarea-id') + '"]');
if (textarea) {
textarea.value = editable.innerHTML.trim();
}
}
$('.editable').append("<img src='abc' />");
$('.editable').each(updateTextArea);
The updateTextArea function will update a text area corresponds to editable area.
Here is the code I tried
var editor = new MediumEditor('.editable', {
buttonLabels: 'fontawesome'
});
function updateTextArea(index,editable){
var textarea = editable.parentNode.querySelector('textarea[medium-editor-textarea-id="' + editable.getAttribute('medium-editor-textarea-id') + '"]');
if (textarea) {
textarea.value = editable.innerHTML.trim();
}
}
$("#addImage").click(function(){
$('.editable').append("<img src='abc' />");
$('.editable').each(updateTextArea);
});
$('.editable').change(updateTextArea);

<input type="button" id="addImage" value="Add Image">
<input type="button" value="Alert textarea content" onclick="alert(document.getElementById('markdown').value)">
</div>
If you use the setContent() method of the editor (documentation here), this will allow you to add content and the editor will detect the change and fire all the proper events. This should include notifying the markdown extension that the content has changed and that should update the markdown.
So, instead of this:
$('.editable').append('<img src="abc" />');
Try this:
editor.setContent(editor.getContent() + '<img src="abc" />');
This also leverages the getContent() method (documentation here).
NOTE: These examples assume you're only using a single editor element for MediumEditor. If you are passing multiple elements into a single instance of MediumEditor, you may need to specify a value for the index parameter to both setContent() and getContent()
Im trying to make some buttons append text to a textarea with jquery, and I have it working, but only if I dont type anything into the textarea itself.
Code:
<textarea name="comments" id="comments" rows="20" style="margin-left: 0px; margin-right: 0px; width: 968px;"></textarea>
<div>
<button>+petname</button>
<button>+lastvisit</button>
<button>+nextvisit</button>
</div>
<script>
$( "button" ).click(function() {
var text = $( this ).text();
$('#comments').append(text);
});
</script>
This code is working, but the minute I type something else into that text area, the buttons no longer work??? WHY!!?? I just cant figure it out.
Much thanks.
Jason
Instead of doing append set val using its function argument syntax, do this way:
$('#comments').val(function(_, val){
return val + text;
});
Demo
change
$('#comments').append(text);
to
$('#comments').val( $('#comments').val() + " " + text );
how to format the data caption
I am planning to display three different names for a single image
after i click the cube light box opens and the caption comes with div tag
but i wanted to display it one by one on the light box
its working fine without light box
$data = '';
$('[data-caption]').each(function(){
$data += '<div>' + $(this).data('caption') + '</div>';
});
$('body').append('<div id="more-info">' + $data + '</div>');
http://jsfiddle.net/ZrpLT/52/
<body>
<div class="row">
<div class="span10">
<div class="melonhtml5_gallery">
<div data-caption="<div>Paul Scholes</div> <div>Wayne Rooney</div> <div>Sir Alex Ferguson</div>" data-image="http://www.defie.co/designerImages/thumbnails/inventory.png"></div>
</div>
</div>
</body>
http://jsfiddle.net/ZrpLT/63/
This requires updating the Gallery class to use .html instead of .text when the caption is appended specifically in the onClick function on the line:
var m = $("<div>").addClass("caption").html(g ? g : ""),
As long as you are able to do that, you can get this to work for you.
