How to set search input box on header frame in html - html

I have 03 frame (Header, Left_Menu and Content). In header frame I set a search input box. If anyone click on search input box then a blue color div show under the search input box but above content frame. But When I click search input box then blue color div box don’t show above content frame.
I want to create search input box as following example:
But my search input box result show as following example:
Please, anyone can help to solve this problem.

Nowadays <frame> is not recommended. You want to overflow your header onto the content.
This is only feasible, if you don't use frames. You should use for example a simple <div> HTML tag instead of the frames.
After that, you should add some CSS property, which results the desired effect. For example:
#header{
position: relative;
z-index: 2;
heigth: 100px;
}
You should add the z-index property.

Position SVG lines over HTML elements, while still allowing interaction with the HTMl elements [duplicate]

I have a div that has background:transparent, along with border. Underneath this div, I have more elements.
Currently, I'm able to click the underlying elements when I click outside of the overlay div. However, I'm unable to click the underlying elements when clicking directly on the overlay div.
I want to be able to click through this div so that I can click on the underlying elements.
Yes, you CAN do this.
Using pointer-events: none along with CSS conditional statements for IE11 (does not work in IE10 or below), you can get a cross browser compatible solution for this problem.
Using AlphaImageLoader, you can even put transparent .PNG/.GIFs in the overlay div and have clicks flow through to elements underneath.
CSS:
pointer-events: none;
background: url('your_transparent.png');
IE11 conditional:
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='your_transparent.png', sizingMethod='scale');
background: none !important;
Here is a basic example page with all the code.
Yes, you CAN force overlapping layers to pass through (ignore) click events.
PLUS you CAN have specific children excluded from this behavior...
You can do this, using pointer-events
pointer-events influences the reaction to click-, tap-, scroll- und hover events.
In a layer that should ignore / pass-through mentioned events you set
pointer-events: none;
Children of that unresponsive layer that need to react mouse / tap events again need:
pointer-events: auto;
That second part is very helpful if you work with multiple overlapping div layers (probably some parents being transparent), where you need to be able to click on child elements and only that child elements.
Example usage:
.parent {
pointer-events:none;
}
.child {
pointer-events:auto;
}
<div class="parent">
I'm unresponsive
I'm clickable again, wohoo !
</div>
Allowing the user to click through a div to the underlying element depends on the browser. All modern browsers, including Firefox, Chrome, Safari, and Opera, understand pointer-events:none.
For IE, it depends on the background. If the background is transparent, clickthrough works without you needing to do anything. On the other hand, for something like background:white; opacity:0; filter:Alpha(opacity=0);, IE needs manual event forwarding.
See a JSFiddle test and CanIUse pointer events.
I'm adding this answer because I didn’t see it here in full. I was able to do this using elementFromPoint. So basically:
attach a click to the div you want to be clicked through
hide it
determine what element the pointer is on
fire the click on the element there.
var range-selector= $("")
.css("position", "absolute").addClass("range-selector")
.appendTo("")
.click(function(e) {
_range-selector.hide();
$(document.elementFromPoint(e.clientX,e.clientY)).trigger("click");
});
In my case the overlaying div is absolutely positioned—I am not sure if this makes a difference. This works on IE8/9, Safari Chrome and Firefox at least.
Hide overlaying the element
Determine cursor coordinates
Get element on those coordinates
Trigger click on element
Show overlaying element again
$('#elementontop').click(e => {
$('#elementontop').hide();
$(document.elementFromPoint(e.clientX, e.clientY)).trigger("click");
$('#elementontop').show();
});
I needed to do this and decided to take this route:
$('.overlay').click(function(e){
var left = $(window).scrollLeft();
var top = $(window).scrollTop();
//hide the overlay for now so the document can find the underlying elements
$(this).css('display','none');
//use the current scroll position to deduct from the click position
$(document.elementFromPoint(e.pageX-left, e.pageY-top)).click();
//show the overlay again
$(this).css('display','block');
});
I currently work with canvas speech balloons. But because the balloon with the pointer is wrapped in a div, some links under it aren't click able anymore. I cant use extjs in this case.
See basic example for my speech balloon tutorial requires HTML5
So I decided to collect all link coordinates from inside the balloons in an array.
var clickarray=[];
function getcoo(thatdiv){
thatdiv.find(".link").each(function(){
var offset=$(this).offset();
clickarray.unshift([(offset.left),
(offset.top),
(offset.left+$(this).width()),
(offset.top+$(this).height()),
($(this).attr('name')),
1]);
});
}
I call this function on each (new) balloon. It grabs the coordinates of the left/top and right/down corners of a link.class - additionally the name attribute for what to do if someone clicks in that coordinates and I loved to set a 1 which means that it wasn't clicked jet. And unshift this array to the clickarray. You could use push too.
To work with that array:
$("body").click(function(event){
event.preventDefault();//if it is a a-tag
var x=event.pageX;
var y=event.pageY;
var job="";
for(var i in clickarray){
if(x>=clickarray[i][0] && x<=clickarray[i][2] && y>=clickarray[i][1] && y<=clickarray[i][3] && clickarray[i][5]==1){
job=clickarray[i][4];
clickarray[i][5]=0;//set to allready clicked
break;
}
}
if(job.length>0){
// --do some thing with the job --
}
});
This function proofs the coordinates of a body click event or whether it was already clicked and returns the name attribute. I think it is not necessary to go deeper, but you see it is not that complicate.
Hope in was enlish...
Another idea to try (situationally) would be to:
Put the content you want in a div;
Put the non-clicking overlay over the entire page with a z-index higher,
make another cropped copy of the original div
overlay and abs position the copy div in the same place as the original content you want to be clickable with an even higher z-index?
Any thoughts?
I think the event.stopPropagation(); should be mentioned here as well. Add this to the Click function of your button.
Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
Just wrap a tag around all the HTML extract, for example
<a href="/categories/1">
<img alt="test1" class="img-responsive" src="/assets/photo.jpg" />
<div class="caption bg-orange">
<h2>
test1
</h2>
</div>
</a>
in my example my caption class has hover effects, that with pointer-events:none; you just will lose
wrapping the content will keep your hover effects and you can click in all the picture, div included, regards!
An easier way would be to inline the transparent background image using Data URIs as follows:
.click-through {
pointer-events: none;
background: url(data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7);
}
I think that you can consider changing your markup. If I am not wrong, you'd like to put an invisible layer above the document and your invisible markup may be preceding your document image (is this correct?).
Instead, I propose that you put the invisible right after the document image but changing the position to absolute.
Notice that you need a parent element to have position: relative and then you will be able to use this idea. Otherwise your absolute layer will be placed just in the top left corner.
An absolute position element is positioned relative to the first parent
element that has a position other than static.
If no such element is found, the containing block is html
Hope this helps. See here for more information about CSS positioning.
You can place an AP overlay like...
#overlay {
position: absolute;
top: -79px;
left: -60px;
height: 80px;
width: 380px;
z-index: 2;
background: url(fake.gif);
}
<div id="overlay"></div>
just put it over where you dont want ie cliked. Works in all.
This is not a precise answer for the question but may help in finding a workaround for it.
I had an image I was hiding on page load and displaying when waiting on an AJAX call then hiding again however...
I found the only way to display my image when loading the page then make it disappear and be able to click things where the image was located before hiding it was to put the image into a DIV, make the size of the DIV 10x10 pixels or small enough to prevent it causing an issue then hiding the containing div. This allowed the image to overflow the div while visible and when the div was hidden, only the divs area was affected by inability to click objects beneath and not the whole size of the image the DIV contained and was displaying.
I tried all the methods to hide the image including CSS display=none/block, opacity=0, hiding the image with hidden=true. All of them resulted in my image being hidden but the area where it was displayed to act like there was a cover over the stuff underneath so clicks and so on wouldn't act on the underlying objects. Once the image was inside a tiny DIV and I hid the tiny DIV, the entire area occupied by the image was clear and only the tiny area under the DIV I hid was affected but as I made it small enough (10x10 pixels), the issue was fixed (sort of).
I found this to be a dirty workaround for what should be a simple issue but I was not able to find any way to hide the object in its native format without a container. My object was in the form of etc. If anyone has a better way, please let me know.
I couldn't always use pointer-events: none in my scenario, because I wanted both the overlay and the underlying element(s) to be clickable / selectable.
The DOM structure looked like this:
<div id="outerElement">
<div id="canvas-wrapper">
<canvas id="overlay"></canvas>
</div>
<!-- Omitted: element(s) behind canvas that should still be selectable -->
</div>
(The outerElement, canvas-wrapper and canvas elements have the same size.)
To make the elements behind the canvas act normally (e.g. selectable, editable), I used the following code:
canvasWrapper.style.pointerEvents = 'none';
outerElement.addEventListener('mousedown', event => {
const clickedOnElementInCanvas = yourCheck // TODO: check if the event *would* click a canvas element.
if (!clickedOnElementInCanvas) {
// if necessary, add logic to deselect your canvas elements ...
wrapper.style.pointerEvents = 'none';
return true;
}
// Check if we emitted the event ourselves (avoid endless loop)
if (event.isTrusted) {
// Manually forward element to the canvas
const mouseEvent = new MouseEvent(event.type, event);
canvas.dispatchEvent(mouseEvent);
mouseEvent.stopPropagation();
}
return true;
});
Some canvas objects also came with input fields, so I had to allow keyboard events, too.
To do this, I had to update the pointerEvents property based on whether a canvas input field was currently focused or not:
onCanvasModified(canvas, () => {
const inputFieldInCanvasActive = // TODO: Check if an input field of the canvas is active.
wrapper.style.pointerEvents = inputFieldInCanvasActive ? 'auto' : 'none';
});
it doesn't work that way. the work around is to manually check the coordinates of the mouse click against the area occupied by each element.
area occupied by an element can found found by 1. getting the location of the element with respect to the top left of the page, and 2. the width and the height. a library like jQuery makes this pretty simple, although it can be done in plain js. adding an event handler for mousemove on the document object will provide continuous updates of the mouse position from the top and left of the page. deciding if the mouse is over any given object consists of checking if the mouse position is between the left, right, top and bottom edges of an element.
Nope, you can't click ‘through’ an element. You can get the co-ordinates of the click and try to work out what element was underneath the clicked element, but this is really tedious for browsers that don't have document.elementFromPoint. Then you still have to emulate the default action of clicking, which isn't necessarily trivial depending on what elements you have under there.
Since you've got a fully-transparent window area, you'll probably be better off implementing it as separate border elements around the outside, leaving the centre area free of obstruction so you can really just click straight through.

Is it possible to keep this text inside the div that has position absolute set?

I'm creating a web map. I have a div at the top of the map that when clicked maximizes and shows a custom attribute window. The attribute window displays data based on other actions in the map. The attribute window currently has 4 buttons at the top that will change the contents of the window depending on which button is selected.
The actions on the map will send a request to my Python flask web service which returns data formatted in <ul><li></li><ul> that I want to display in the attribute window.
The problem I currently have is that the text goes outside the the window - probably because I have the div set to position: absolute. But is there any way around this?
Here is a working CodePen (click the div at the top):
https://codepen.io/anon/pen/oeJGdm
Thank you for any advice.
Keeping your structure i would suggest few changes, I'm including only the changes in this answer.
First give room for .nav in #atributeWindow.
#attributeWindow {
padding-top: 30px; /*to accomodate nav bar*/
...
}
Move nav to top padding area of #attributeWindow.
.nav{
top: 0;/* to place at top;*/
...
}
Contents will be placed below .nav since padded in #attributeWindow. So remove this padding.
.attributeContent{
/*padding-top:30px; remove this padding.*/
...
}
Finally remove the display:inline
#test1{
/*display: inline;*/
...
}

Add CSS dynamically when hover on button

Here are my website link. I have translate this button on pages. When I hover on translate this button, the language section is shown 50 pixels below.
How can I add css dynamically that add top position to language section. Right now I am using below css
.ttb-panel { top: 235px !important; }
This only works when one div with class .ccm-custom-style-adstop (Advertise after page title ) is not there.
I have given both page link.
What CSS rule will work?
$("# TRANSLATE BUTTON ID").mouseover(function(){
$("# TRANSLATE DIV ID").addClass("ttb-panel");
});

File upload button and odd text cursor behavior in IE

I've built an upload button that's formatted to look like your typical html button, instead of the browser standard file upload form. The approach was to style an anchor element and overlay a transparent file input element on top.
This approach works fine in all browsers but IE. In IE, when the user clicks the upload button a text cursor appears as if the user had clicked on a text input box. The user can trigger the file upload dialog by double clicking the button. But this isn't the behavior we want or that anyone expects.
I'm at a loss as to why this is happening. I've set up a jsfiddle demonstrating the issue here:
http://jsfiddle.net/davelee/yfSmc/3/
Meet this bug on IE11, fix it with font-size: 0;
I have just worked on this exact issue. With IE, yes, there is a small area on the left of the button that acts as a text input (for the file name to be entered manually). The solution that I figured out was to increase the font-size of the input field. Strange, I know, but by increasing the font-size, you increase the "Browse..." button portion of their input field, and therefore increase the clickable area and push out the text portion of their upload button. Since the button is transparent anyway, nobody is the wiser :)
Setting the width and height of the file input element fixes the issue in both ie8 and ie9.
http://jsfiddle.net/davelee/yfSmc/4/
Take a outer div to that input file apply over flow hidden and width to it, then to the input file apply some css like: font-size, margin-left in negative.
<div class="outerWrap">
<input type="file" id="fileUpload"/>
</div>
and the css will be:
.outerWrap {
width: 200px;
height: 50px;
overflow: hidden;
}
#fileUpload {
width: 210px;
height: 50px;
margin-left: -10px;
font-size: 70px;
}
adjust the width and margin-left according to your requirement.
for reference got this link: http://jsfiddle.net/TrdJ8/
and try it out on IE-9
try adding css
z-index
to your absolute elements.
lowest element
z-index:1
highest
z-index:2;
and set a z-index on the container element.

A simple tab implementation with <ul><li> but how to set tab background-image?

I implemented a simple tab navigation by using <ul><li><a> , the problem is that there are several "layers" on each tab still needed. what I mean is, In my current implementation I have:
-tab text which is <a>text</a>
-on each tab I have a tab icon image, which I put on <li> as background-image of <li>,
But I still need:
-tab seperator image (A vertical bar image) which I intend to put on <a>,and position it on the left side background-position: left , it is working but this implementation is not in my code which I showed below on jsfiddle site because I did not find a suitable image on internet
-tab background image which occupy the whole tab, I have no idea where I should put this image?
Please check & run my implementation here on jsfiddle, in the css code, I used background-color instead of background-image just to express what I want to achieve, but I need to use background-image as the tab background.
What I tried:
I tried to put the tab background image on <li> but it will hide the
icon image which has already on <li>,
I tried to put the tab background image on <a> but it will also hide the tab seperator image when mouse hover
How to get rid of this layer probelm on tab implementation then? (Please do not suggest me to use less image, since it is one requirement of this app to use those images.)
(By the way, all images I mentioned have mouse "hover" counterpart)
If you don't want to change the HTML, you can use pseudo-elements:
Fiddle: http://jsfiddle.net/Pq7LC/39/
li:before{
content: "";
background: pink;
width: 20px;
height: 61px;
display: block;
position:absolute;
}
li:first-child:before{ /* Don't add image border before first li */
content:none;
}
You can do it with css, no need of images.

Hope it helped you :)
