When someone hover my site title, the background changes forever, I want the title to disappear forever too.
<h1 onmouseover="changeBodyBackground()">{Title}</h1>
function changeBodyBackground() {
document.body.style.background = "url(http://i.imgur.com/EyWVWO7.gif)";
document.body.style.backgroundSize = "Cover";
}
The code is the background html and javascript, I want to remove the title (h1).
Assign and ID
<h1 id="title" onmouseover="changeBodyBackground()">{Title}</h1>
At the end of the JavaScript function
document.getElementById('title').style.display = 'none';

I am a beginner in html. I have an image that has to be displayed on the overlay,when a button is pressed. Th problem is the image doesnot appear on the overlay for the first time. It appers only from the second time and then it works properly. If I refresh my page and do it again the image does not appear. The removing part has no error. So i did not include that part of the code.
var overlay = $(".ui-widget-overlay");
baseBackground = overlay.css("background");
baseOpacity = overlay.css("opacity");
overlay.css("background", "#000").css("opacity", "1");
function ShowOverlay() {
$("<div id='overlay'> <img src='Images/ajax.gif'/> </div>").appendTo('body');
$('#overlay').show();
Is it possible to add the image below _overlay.css("background", "#000").css("opacity", "1"); _ ?
On the following site:
Link to site with issues
I have three buttons at the bottom of each thumbnail (hover to see them). The three buttons open up a prettyphoto box that uses the title attribute under the image (hidden as white currently next to the gallery nav buttons).
I need the HMTL title attribute to remain within the HTML. I just do not need the ugly tooltip when you hover over the buttons.
Does anyone know how to remove hover title tooltip on links?
I think you are after a workaround like this:
First put a class suppress on every link you want its tool-tip to be removed on hover:
<a class="suppress" title="">link text</a>
Then you may have this snippet in your code:
var links = document.getElementsByTagName('a');
for (var i = 0; i < links.length; i++) {
if (links[i].className == 'suppress') {
links[i]._title = links[i].title;
links[i].onmouseover = function() {
this.title = '';
}
links[i].onmouseout = function() {
this.title = this._title;
}
}
}
So I have this:
clicking here
<a name="link">goes here</a>
Simple, but the problem is that my site has a fixed position header that stays at the top of the page, so when a user clicks on the link, the place I want them to go to is hidden by the header. So I guess where I really want them to end up a certain amount of pixels above what I actually want them to see. I've tried putting the destination link above where I want them to end up, but it's a block of text so it changes with different screen sizes and therefore isn't consistent.
I'm wondering if there is any way to solve this problem, perhaps something with css.
Thanks in advance.
I realise this is over a year old, but for the benefit of anyone else who comes across it:
A slightly simpler solution is to put padding at the top of the section you are targeting with the link.
HTML:
<section id="section_name">
...Your stuff here...
</section>
CSS:
#section_name {
padding-top: 40px;
}
You could use a jQuery method so that when a link with a # is clicked, it finds the position of the element it's meant to go to and then moves to a position X number of pixels above the target.
Something like this:
$(function(){
var positionOffset = 50;
$('a[href=*"#"]').click(function(){
var targetHash = this.hash;
if(targetHash.length > 0 && targetHash == window.location.hash){
var elementPosition;
if($(targetHash).length){
elementPosition = $(targetHash).offset();
} else {
var targetAnchor = targetHash.replace("#", "");
elementPosition = $('a[name="' + targetAnchor + '"]').position();
}
$(window).scrollTop(elementPosition.top - positionOffset);
return false;
} else {
return true;
}
});
});
i have simple application which should work on keyboard events like onfocus and onblur instead of onmouseover and onmouseout.
here is my code snippet to zoomin/zoomout:
<script>
var nW,nH,oH,oW;
function zoom(iWideSmall,iHighSmall,iWideLarge,iHighLarge,whichImage)
{
oW=whichImage.style.width;oH=whichImage.style.height;
if((oW==iWideLarge)||(oH==iHighLarge))
{
nW=iWideSmall;nH=iHighSmall;
}
else
{
nW=iWideLarge;nH=iHighLarge;
}
whichImage.style.width=nW;whichImage.style.height=nH;
}
</script>
calling this function in this way:
<td align=center valign=middle >
<figure>
<button style="background-color:black; height:160px;width:160px ; border:none"><img src="F:\rashmi\icons_tv\Help_Normal.png" onfocus="zoom('57px','120px','96px','136px',this);"
onblur="zoom('57px','120px','57px','120px',this);" > </button>
<figcaption><font size="5" color="white" style="font-weight:bold"><center>help</center></font></figcaption>
</figure>
</td>
but problem is when i select image using tab key i cant see any zoomin/zoomout effect. if i replace onfocus/onblur with onmouseover/onmouseout respectively it works well.
please some one help me where i am going wrong.
regards
rashmi
You will not get focus on an img element by tabbing but on the button element instead. Move your onblur/onfocus events to the button element. This will change your button's size each time you focus/lose focus on it, but it will not change your image size. What you have to do then is to modify your code so the change is mapped on the button's contained image dimensions as well. Something that I can think of right now is
<script type="text/javascript">
var nW,nH,oH,oW;
function zoom(iWideSmall,iHighSmall,iWideLarge,iHighLarge,whichElement)
{
theImage = whichElement.firstChild;
theImage.style.width=nW;theImage.style.height=nH;
oW=whichElement.style.width;oH=whichElement.style.height;
if((oW==iWideLarge)||(oH==iHighLarge))
{
nW=iWideSmall;nH=iHighSmall;
}
else
{
nW=iWideLarge;nH=iHighLarge;
}
whichElement.style.width=nW;whichElement.style.height=nH;
theImage.style.width=nW;theImage.style.height=hH;
}
</script>
Here, the first child of the button element, which happens to be the image, takes the same height and width with the button, whenever that changes.
In my site, I would like to implement a textbox where people can input a set of strings separated by a separator character.
For example the tags textbox at the bottom of this page: tags(strings) delimited by space(separator).
To make it more clear to the user, it would make a lot of sence to give each string a different background color or other visual hint.
I don't think this is possible with a regular input[text] control.
Do you deem it possible to create something like that with javascript? Has somebody done this before me already? Do you have any other suggestions?
Basic Steps
Put a textbox in a div and style it too hide it.
Make the div look like a text box.
In the onClick handler of the div, set the input focus to the hidden text box.
Handle the onKeyUp event of the hidden text box to capture text, format as necessary and alter the innerHtml of the div.
Tis quite straightforward. I'll leave you to write your formatter but basically you'd just splitString on separator as per the Semi-Working-Example.
Simple Outline
<html>
<head>
<script language="javascript" type="text/javascript">
function focusHiddenInput()
{
var txt = document.getElementById("txtHidden");
txt.focus();
}
function formatInputAndDumpToDiv()
{
alert('Up to you how to format');
}
</script>
</head>
<body>
<div onclick="focusHiddenInput();">
Some label here followed by a divved textbox:
<input id="txtHidden" style="width:0px;" onKeyPress="formatInputAndDumpToDiv()" type="text">
</div>
</body>
</html>
Semi-Working Example
You still need to extend the click handlers to account for tag deletion/editing/backspacing/etc via keyboard.... or you could just use a click event to pop up another context menu div. But with tags and spacer ids identified in the code below that should be pretty easy:
<html>
<head>
<script language="javascript" type="text/javascript">
var myTags=null;
function init()
{
document.getElementById("txtHidden").onkeyup= runFormatter;
}
function focusHiddenInput()
{
document.getElementById("txtHidden").focus();
}
function runFormatter()
{
var txt = document.getElementById("txtHidden");
var txtdiv = document.getElementById("txtBoxDiv");
txtdiv.innerHTML = "";
formatText(txt.value, txtdiv);
}
function formatText(tagText, divTextBox)
{
var tagString="";
var newTag;
var newSpace;
myTags = tagText.split(' ');
for(i=0;i<myTags.length;i++) {
newTag = document.createElement("span");
newTag.setAttribute("id", "tagId_" + i);
newTag.setAttribute("title", myTags[i]);
newTag.setAttribute("innerText", myTags[i]);
if ((i % 2)==0) {
newTag.style.backgroundColor='#eee999';
}
else
{
newTag.style.backgroundColor='#ccceee';
}
divTextBox.appendChild(newTag);
newTag.onclick = function(){tagClickedHandler(this);}
newSpace = document.createElement("span");
newSpace.setAttribute("id", "spId_" + i);
newSpace.setAttribute("innerText", " ");
divTextBox.appendChild(newSpace);
newSpace.onclick = function(){spaceClickedHandler(this);}
}
}
function tagClickedHandler(tag)
{
alert('You clicked a tag:' + tag.title);
}
function spaceClickedHandler(spacer)
{
alert('You clicked a spacer');
}
window.onload=init;
</script>
</head>
<body>
<div id="txtBoxDivContainer">
Enter tags below (Click and Type):<div id="txtBoxDiv" style="border: solid 1px #cccccc; height:20px;width:400px;" onclick="focusHiddenInput();"></div>
<input id="txtHidden" style="width:0px;" type="text">
</div>
</body>
</html>
Cursor
You could CSS the cursor using blink (check support) or otherwise just advance and hide as necessary an animated gif.
This is quite interesting. The short answer to your question is no. Not with the basic input element.
The real answer is: Maybe with some trickery with javascript.
Apparently Facebook does something close to this. When you write a new message to multiple persons in Facebook, you can type their names this sort of way. Each recognized new name is added a bit like an tag here and has an small cross next to it for removing it.
What they seem to do, is fake the input area size by drawing an input-looking box and removing all styling from the actual input with css. Then they have plenty of logic done with javascript so that if you have added an friend as a tag and start backspacing, it will remove the whole friends name at once. etc.
So, yes, it's doable, but takes plenty of effort and adds accessibility problems.
You can look how they do that at scripts like TinyMCE, which add such features to textareas. In textareas you can use HTML to colorize text.
You can use multiple textboxes
textbox1 <space> textbox2 <space> textbox3 ....
and so on... You can then apply the background-color style to each textbox.
