Amending Textarea Content Onfocus/onblur?

Nov 6, 2009

I've just found out that a piece of code is not working as expected in certain browsers - but the way in which it goes wrong is not consistent, so maybe it's something wrong with my code.Oddly enough, it works exactly as I was expecting when viewed in IE.Here's the code...

OnFocus/onBlur

Jul 23, 2005

For those who have been using Outlook Express, you must be pretty used to
the fact that whenever you focus on the preview section, the header for the
preview turns from grey to blue, while the text turns from black to white.

Using OnFocus / OnBlur Event On Input Box

Dec 4, 2010

I want to have a function on an event
<span id= "nameheader"> </span>
<form method ="post" action="send.php">
<input
id = "nameinput"
class = "input"
value = "name"
onfocus = "focus();"
onblur = "blur();"
/>

That is when you focus on the input box the value ' name' gets put above the box and when you focus on something else it goes back to the box.
this is my function
focus(){
document.getElementById('nameheader').innerHTML = 'name';
document.getElementById('nameinput').value = '';
}
And I would obviously do the opposite for onblur event.

AJAX :: Auto-complete And Onblur/onfocus?

Jan 22, 2009

I have a text input field - a search box. As characters are entered, I use AJAX to retrieve a list of matches from my products table and display them in a simple unordered list below the search box.This works great, until the user clicks one of the matches.Because I have set the onblur event of the search box to hide the autocomplete box, when the search box loses focus as a result of one of the links in the autocomplete box being clicked, the autocomplete box is hidden and the link is not activated.How can I get the links to work, and also have the autocomplete options disappear when the search box loses focus?

Onfocus And Onblur Events Don't Work Correctly?

Sep 9, 2009

I have a page with a textbox that I want to have a message written inside it that will dissapear when the user clicks in the text box and writes something and it will show up again if the user clicks somewhere else but hasn't written anything inside the textbox. So I am using the onfocus event in order to write "Enter your email here" and the onfocus event in order to show the "Enter your email here" message inside the textbox if the user clicks somewhere else in the webpage but has left the textbox blank. If however the user has written, for exampl "jim@yahoo.com", I want this to remain in the textbox.What am I doing wrong?

Amending Right Click Menu To Download Audio From JPlayer?

Mar 24, 2011

I am using a javascript audio player on a webpage that has an option to download the track by right clicking on a link called 'mp3' at the end of each track in the playlist. When the user right clicks on the track name however all that can be downloaded is an html file.

I am trying to find a way of changing this so that right clicking on the track and choosing the 'save link as' option will download the mp3. I have been led to believe that I can use a script such as this one:

[URL]

to generate a custom content menu for downloading tracks, or somehow downloading the mp3, but I am at a loss at to how to do this.

Here's a screenshot of a track in the playlist:

[URL]

And here is the source:

Code:

{name:"foster manganyi na tintsumi ta tilo - zion (ndzi teke riendzo no. 1) <span style="color:#BDBDA1; font-size:12px;">[from nick]</span>",mp3:"./songs//nick/zion.mp3"}

Getting Content Of A Textarea With AJAX

Jan 22, 2009

I'm trying to achieve something that I originally thought would be very simple, but I can't get it working....and even googling hasn't helped this time! All I want to do is update the innerHTML of a div with the content of a textarea object when a button is clicked. I'm trying to avoid having to post the form using AJAX because the button also replaces the innerHTML of a different div with the value of a text input box. Here is the code I've tried, but it doesn't work:

Code:

function previewContent(intContentId) {
var titleText = document.getElementById('edit_title_' + intContentId);
var titleDiv = document.getElementById('content_title_' + intContentId);

[Code]....

In this example, the titleText var represents the text input box, and the contentText var is the textarea. The titleDiv gets correctly updated with the current value of the input box, but the contentDiv doesn't seem to consider any changes I make within the textarea - it just loads the original content. This seems very strange to me. Is there an easy way to retrieve the value of the textarea?

JQuery :: Populating Div With Textarea Content?

Apr 4, 2011

I am trying to populate a preview div with the content of a textarea. I have 2 textareas on the page. One with ID compose and another with ID profile_signature. Each has its own preview button named respectivly #profile_sig_preview and #msg_preview. however no matter which button is clicked the div is always populated with the content of the first textarea ie profile_signature. I tired setting up 2 divs so the content could be seperated but that did the same thing.

$j('#preview_msg_btn').click(function(){
$j('#preview').html($j('textarea#compose').val());
alert($j('textarea#compose').val());

[Code]....

as you can see iam alerting out both textareas html content and the alert shows the content fine. Just not the div.

Display Textarea Content Elsewhere On The Same Page?

Nov 23, 2010

I have a simple how to question and I'm fairly sure the answer is equally simple, however I'm new to web developing and searching the web didn't help me any further either. Maybe the question hasn't been raised because the answer is too obvious?

Anyway: I want to have one classic textarea/textbox with a submit button, such that when some one enters text in this area and hits the submit button, this same text is displayed elsewhere on the page (this may be displayed in a second textarea as long as I can hide its area borders so it looks as if the text gets displayed on the page itself). Preferably, the input text in the first area should be pretty standard, but the displayed content should be larger and in a different font.

Calling Parent Onblur Event After Child Onblur Event?

Jul 2, 2009

I am having one td and inside td using one control(it may be any control like textbox,combobox) and am using onblur events for td and aswell as the control inside td. when am moving focus from this td to another td the parent onblur event is firing first and then child control(like textbox, combobox) onblur event is firing. The problem is am validating that entire td (what ever the value user updates) in one method. so in this scenario that validate method is calling when i move the focus onto child control. After entering the value in the child control that child control onblur event is firing and am unable to fire the parent control(td) onblur event.

JQuery :: Textarea/Textbox Html Content Encoding To Satisfy .Net 4.0 Validation Test

Sep 19, 2011

I have web form (not MVC) that has bunch of textarea and textboxes where user can input HTML markup. For example, a textarea is provided so users can put YouTube embed iframe html tag where it will be shown on their profile. The problem is that asp.net 4.0 http request validation doesn't like things like ">" or "<", etc. I can put pagevalidation="false" on the page and/or revert back to .net 2.0 validation but why would I want to do that since I have geniuses like you guys that can show me how to do what I want with jquery without jeopardizing security.

So what I want to do is form a handler so when the form is submitted, the content of the textboxes and textarea on the page be encoded (i.e. > to > etc.) before the submission to the asp.net 4.0 so we can keep the httprequest validation stuff happy. I have added a class "mustEncode" to each of the textarea and textboxes.

Trying To Work With Onfocus

Jul 23, 2005

Here is the layout of my form from left to right, from top to down.

- buttonA, buttonB, buttonC
- textbox, textbox, textbox
- buttonXXX

After the user types in the textboxes and press enter (with the cursor still
in one of the textboxes), buttonXXX should be pressed by default.(the user
is too lazy to take the cursor over to buttonXXX and click).

The problem is the top/left most button (button A) gets pressed which annoys
them to death. So I tried to do this.

In the bottonA's onfocus event handle-
document.forms[0].elements['buttonXXX'].focus() .

Result: ButtonXXX receives focus alright, but the code for buttonA still
executes!

Onfocus For A <select>

Jul 20, 2005

I'm fairly new to this and my code is as follows...

<script language="JavaScript>
var oldValue

function focusElement(theElement) {
oldValue = theElement.value;
return;
}
</script>

Then in the HTML, I have

<select size="1" id="ConfCommentSELECT" name="ConfCommentSELECT"
onfocus="return focusPrecedence(this);">
<option value="0"> - </option>
<option value="1">1</option>
<option value="2">2</option>
</select>

The <select> is with a <form><tr><td>, but I don't see how that would make a
difference. I started using the onchange="return blah-blah-blah(this);" and
that worked so I copied that to the onfocus. What I want to do is to
remember the value of the contents of the <select> before the user changes
it, and compare it to the new value.

Onfocus Event For Hyperlinks

Oct 8, 2005

I'm developing a website where a visistor does not have to use the mouse.
All he has to do is use the Tab-key or key-combinations to jump to specific
hyperlinks (containing accesskeys). Next, he presses the Enter key to follow the hyperlink.

My question is: is it possible to change color of the hyperlink when a
hyperlink get the focus. I do not only want to see the dotted line, I want the hyperlink to lighten up.
