Using Ctrl-F in most browsers will allow you to search for text, but only in only the text areas. I would like to search for text in what should be accessible areas that are not necessarily text rendered areas such as <map ...><area title="searchable text" /></map> and <img alt="searchable text" />. Is there a browser or addon that will do what I'm asking for? This stuff is here for accessibility, but it doesn't seem to be really all that accessible (except by mouse hover, which again isn't all that accessible).
NOTE
An answer that is required, does not use something that is decoupled from the view. I.e. searching through the source code isn't an option as this is largely difficult to read (esp on complex pages) and doesn't show where the information is located on the rendered page.
Is there a browser or addon that will do what I'm asking for?
Oh yes. Lynx browser does it.
But I guess it's not a solution ;-)
If your question is so, there is no way to override what CTRL+F is doing in your browser.
You can design a custom plugin inside your website, or an addon for your browser. This would be quite easy... but will require other shortcut.
If your main problem is to locate tags based on their alt or title attributes content, this is quite easy in javascript:
var search='enter image';
var nodes=document.querySelectorAll("[alt*='"+search+"'],[title*='"+search+"']");
You can then highlight the matching nodes using jquery or what you want.
for (i in nodes) {
nodes[i].className+=' resultHighlighted';
}
and scroll to the first result:
nodes[0].scrollIntoView();
If you intend to create a browser plugin, you can create your custom a bookmarklet or a custom plugin, and associate a shortcut to this bookmark (see https://github.com/iSunilSV/Chrome-Bookmark-Shortcut)
A simple bookmarklet to find the first match by title or alt attribute and scroll to it will be something like that:
javascript:text=prompt("search inside alt or title attribute");
document.querySelector("[alt*='"+text+"'],[title*='"+text+"']").scrollIntoView();
In your browser, use the "View Source" or "Source Code" function, and then within that window that pops up, use the Ctrl-F for Find.
You can also use the "Inspect Element" directly on an element to split the screen into two windows- one for code and one that's rendered.
For more information, here's a sample article for Chrome:
https://support.google.com/adsense/answer/181951?hl=en
Would something like the Web Developer browser plugin work? It's available for Chrome, FF and Opera. There are a few features that toggle the display of various attributes such as title, alt and even ARIA roles. This injects the attribute text inline with the element.
In my opinion, it's not a bug; they were just not designed for this use.
As I'm sure you are aware, the alt attribute replaces the image when it's not available. So how could you scroll to something that is not always displayed? Whereas you seem to be after a permanent description; a figcaption would be more appropriate for this.
As for the title attribute, it was intended to merely clarify the purpose of a link. There should not be any new information to the user in the title; therefore I think it would be redundant to have two lots of the same information highlighted in one place.
The purpose of searching is to find text on screen, seeing as neither title or alt are always displayed I think the user would be more confused by the fact that nothing is highlighted, and that they are just taken to an image or random link/area. If the image has a figcaption that becomes highlighted, then it would make sense to them. Besides, how are they going to search for the title if they don't know what to search for? Title and alt do not come up in text displayed by search engines; the user will never know about it unless they've been to your site before, in which case they'll know where to look.
Also you state the following:
This stuff is here for accessibility, but it doesn't seem to be really all that accessible
Which, understandably, seems true to you as you probably do not need it. However alt and title are read out to those who use screen readers so isn't entirely useless.
Idea 1
I assume you have Windows and Firefox installed
I have my Firefox installed with 2 add-ons.
Install a add-on called Tile Tabs, it make it possible for example left side is web view and the same page on right side with source code.
Install add-on called Web page to source code & viceversa that make it possible to toggle between view and source code by pressing on CTRL+SHIFT+S
Since what you required is not a default thing in all nowadays browses as far as I know.
Screen shot of the solution:
Idea 2
Install FireBug, you can view/edit/debug source codes and view HTML live and what you highlight on the code will be also highlighted on the view.
Screen shot:
Note: Btw idea 1 is not only good for view / source code but it is also good to compare two views or read article to the right and answer question to the left.
You can use the search funktion in Chrome's developer tools "Elements" Tab (Press F12 -> Tab "Elements" -> Press CTRL + F) and use XPath on your searches. Example:
//*[#title="Google"]
Matches will be shown with a yellow background in the code and when you hover it, its position will be hightlited in the view.
Dev Tools "Element" Search with XPath
It is coupled with the view, allows you to see the element's position and it's also an out-of-the-box solution in Chrome (tested in Chromium 45 for Ubuntu).
Hope it helps!
Regards
EDIT
Forgot - If you want to use wildcards on your searches, you can also do it like this:
//*[contains(#title, 'Google')]
EDIT 2
For the posterity! Further research shows that your goal might be possible to achieve using the Firefox-Addon Greasemonkey, which allows you to customize the way a web page displays or behaves, by using small bits of JavaScript.
I performed several tests with this addon and could achieve a nice effect with simple images (display the ALT attribute as a DIV overlapping the image), but with area sections the thing gets a lot more complicated, as area regions can be squares, circles, and polygons with infinite coordinates plus retrieving the exact positioning of the area itself can be a bit tricky but maybe gives you or someone else a start point.
Based on the ALT Tooltips Script (http://greasemonkey-user-scripts.arantius.com/alt-tooltips-for-firefox), I created the following script and defined it in Greasemonkey:
// ==UserScript==
// #name Alt Tooltips 2
// #namespace http://www.biterion.com
// #description Alt Tooltips 2
// #include *
// #grant all
// ==/UserScript==
function getPosition(element) {
var xPosition = 0;
var yPosition = 0;
while(element) {
xPosition += (element.offsetLeft - element.scrollLeft + element.clientLeft);
yPosition += (element.offsetTop - element.scrollTop + element.clientTop);
element = element.offsetParent;
}
return { x: xPosition, y: yPosition };
}
function getAreaPosition(element) {
var position = element.coords.split(',');
xPosition = position[0];
yPosition = position[1];
return { x: xPosition, y: yPosition}
}
var res = document.evaluate("//img",document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
var i, el;
for (i=0; el=res.snapshotItem(i); i++) {
if(el.alt) {
alternate = el.alt
} else {
alternate = "No alt text";
}
position = getPosition(el);
var newDIV = document.createElement ('div');
newDIV.innerHTML = "<div style='position:absolute;background:yellow;color:black;top:" + position["y"] + ";left:" + position["x"] + "' id=" + i + ">" + alternate + "</div>";
document.body.appendChild(newDIV);
}
var res2 = document.evaluate("//area",document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
var i2, el2;
for (i2=0; el2=res2.snapshotItem(i2); i2++) {
if(el2.alt) {
alternate2 = el2.alt
} else {
alternate2 = "No alt text";
}
position2 = getAreaPosition(el2);
var newDIV2 = document.createElement('div');
newDIV2.innerHTML = "<div style='position:absolute;background:yellow;color:black;top:" + position2["y"] + ";left:" + position2["x"] + "' id=" + i2 + ">" + alternate2 + "</div>";
document.body.appendChild(newDIV2);
}
As you can see, the script firstly detects all "img" and "area" elements, extracts its positioning and creates a new DIV element containing the "alt" attribute, which is then positioned on the upper left corner of the image.
As stated, the problem with areas is, that the positioning should be relative to the parent image and not absolute like in the script, plus the coordinates should be extracted accordingly to the type of area shape (currently only extracting the two first coordinates of each area, which will work for squares but will surely fail for other shapes).
Hope this will help someone :-D

This question already has answers here:
Change last letter color
(8 answers)
Closed 9 years ago.
I am trying to apply some css to the current viewed menu item on a WordPress site. I can apply css to the whole item, but want to apply something to specifically just the last character.
Does anyone have any thoughts on how to go about this?
Thanks.
The is no cross browser solution to achieve it using pure CSS.
You can either using PHP or javascript to get the last character and style it or you can wrap that last character in another element like <span> and style it using css as normally.
EDIT: Here is the javascript approach:
<p class="test">This is a test</p>
var targets = document.getElementsByClassName('test');
for(i=0; i<targets.length; i++) {
var html = targets[i].innerHTML;
targets[i].innerHTML = html.substr(0, html.length-1)
+ "<span class='lastChar'>"
+ targets[i].innerHTML.substr(-1)
+ "</span>";
}
Fiddle Demo
As Felix said, there is no cross browser solution to achieve it using pure CSS. I would reccommend writing simple js code to split menu item and add span with class to last letter.
$('document').ready(function() {
var item = $('.current-menu-item').children().html();
$('.current-menu-item').children().html(item.substr(0, item.length - 1) + '<span class="last">' + item.substr(-1) + '</span>');
});
I was wondering how to ignore the div tag in this bit of code until a certain screen size is reached (767px) but still display everything inside.
<div class="parent">
<h4 class"title">Title</h4>
<ul>
<li>Cities</li>
</ul>
</div>
I'm unsure what you mean by ignore but still display everything inside, so this may not be exactly what you're looking for. However, I would detect screen size and change using JQuery events, and adjust the display accordingly. For example:
function ShowHideParent() {
if($(window).width() >= 768 && $(window).height >= 480)
$('.parent').show();
else
$('.parent').hide();
}
$(document).ready( function () {
ShowHideParent();
});
$(window).resize( function () {
ShowHideParent();
});
If you elaborate more on exactly what you want and why, we might be able to find a better solution. I have a feeling that you might be using this as a workaround for small displays such as the ones on mobile devices. If that is the case, then you may be interested in checking out a web front-end framework such as Foundation. These frameworks have taken care of a lot of the hassle of accommodating a variety of screen sizes, and can help display your content cleanly without having to resort to hacky workarounds.
You'll need to use Javascript.
Why do you not remove only the class of the element? Like this:
var parentClass = 'parent';
if ($(window).width() >= 767) {
var p = $('.parent');
p.removeClass('parent');
} else {
p.addClass('parent');
}
<div class="parent">
<h4 class "title">Title</h4>
<ul>
<li>Cities</li>
</ul>
</div>
I have been searching for an uncomplicated solution to how an image (png) can be zoomed in and out without affecting the rest of the website, but found none.
Have any of you used such a tool or know a way to do this using jQuery or javascript? I am very new to jQuery, so don't know what events I should look at. This functionality should work on both android tablets and iPad.
Looked at JQuery Mobile Pinch Zoom Image Only and the links provided but apparently those are for the ones using PhoneGap.
Thanks for any help.
I did not find a solution either so I implemented it myself (using vanilla JS and canvas but portable to css3) : https://github.com/rombdn/img-touch-canvas
Example : http://www.rombdn.com/img-touch-canvas/demo (better with a touch device but works on desktop with +/- and mouse drag)
<html>
<body>
<div style="width: your_image_width; height: your_image_height">
<canvas id="mycanvas" style="width: 100%; height: 100%"></canvas>
</div>
<script src="img-touch-canvas.js"></script>
<script>
var gesturableImg = new ImgTouchCanvas({
canvas: document.getElementById('mycanvas'),
path: "your image url"
});
</script>
</body>
</html>
I would place the image in a "viewport" layer that is used to maintain the flow of your page. The "viewport" element would have it's overflow CSS property set to hidden to achieve this goal.
You can then use JavaScript to detect multiple touches and then scale the image as necessary. I have yet to use this frameworks but it seems very cool and could help make this easier on you: https://github.com/HotStudio/touchy
You can also detect multiple touches without a framework by watching the event.touches array inside an event handler for touchmove. For each touch occurring simultaneously there will be another index in the event.touches array.
Using Touchy seems pretty easy (untested):
var handleTouchyPinch = function (e, $target, data) {
$target.css({'webkitTransform':'scale(' + data.scale + ',' + data.scale + ')'});
};
$('#my_div').bind('touchy-pinch', handleTouchyPinch);
I'm creating a blog (via tumblr) and I'd like my page titles to automatically scale to fill the available space horizontally, and perhaps to push the content down a little at the same time.
(by scale, I mean the changing the font size, and perhaps word spacing)
The page titles will all be four words long, so there will probably be between 16 and 40 characters.
I know very little about html, and I'd be extremely grateful to anyone who could help me out. Cheers!
Notice : It's not a pure html/css solution .. I don't think it possible to do it with only html and css so It uses javascript intensively. Also I'm using jquery to do it but it could be easily reproduced with any of the javascript libraries out there. (I'm using a javascript library mainly for two reasons : 1st is the cross-browser compatibility that those libraries brings, as well as the well-tought shortcuts/utility functions and the 2nd reason is the high quantity of plugins that those libraries have to handle most of the situations or to bring free eye-candy to websites)
Hi I didn't find any 'out-of-the-box' solution for this, but it's something I always liked in iphone development and that I missed back in web dev so I decided to give it a try
Here is my solution, it's not perfect but it kinda works :p . I tough it would be not too difficult but I took me some time, anyway I think I might use it some day ... or some knowledge I acquired in the process ...
It has inspirations from this question where they depict a solution based on a loop where they increase/decrease the text size until it fits. But I was not satisfied with a loop for each text to resize and I was sure it could be calculated directly instead of trial-error'ed !
It has also inspirations from here for the window resize handling.
Now stop the chatting, here is the code :
<script type="text/javascript">
var timer_is_on=0;
jQuery.event.add(window, "load", loadFrame);
jQuery.event.add(window, "resize", resizeFrame);
function loadFrame() {
$(".sc_container").each(function(){
var $sc = $(this).children(".sc")
$sc[0].orig_width=$sc.width();
//console.log("saving width : "+$sc[0].orig_width+" for "+$sc[0])
});
resizeFrame()
}
function resizeFrame()
{
$(".sc_container").each(function(){
var $sc = $(this).children(".sc")
var wc = $(this).width();
var scale = 0
if (wc > $sc[0].orig_width) {
scale = wc / $sc[0].orig_width;
} else {
scale = - $sc[0].orig_width / wc;
}
//console.log("applying scale : "+scale+" for "+$sc[0])
$sc.css("font-size",scale+"em")
});
}
</script>
</head>
<body>
<div id="container">
<div class="sc_container">
<div class='sc'>SOME SUPER TITLE !</div>
</div>
<div class="sc_container">
<div class='sc'>ANOTHER ONE !</div>
</div>
<div class="sc_container">
<div class='sc'>AND A THIRD LOOOOOOOOOOOOOONG ONE :) !</div>
</div>
<div> And some normal content</div>
</div>
And here is a test page
It's not really robust .. it doesn't work well when the window is less than 400 px wide, and I only tested it on safari,firefox,chrome on mac.
A little tricky part is that I wanted it to work with multiple texts and so the $(".sc_container").each loop that runs on all the objects with css class ".sc_container".
A last trick is that I use the power of the css 'em' unit : for example '3em' mean 3 times the original text size, so here I can use this to scale from the original text size to the desired text size .. that's why I save the original text width on the DOM objects themselves : $sc[0].orig_width=$sc.width(); and reused it for computations later on resize, otherwise it was messed up after multiple resizes.
What do you guys think about it ?
