I'll try to explain:
I have numerous div classes, but for the sake of simplicity, let's say I only have 3.
Someone is viewing DIV 1, and I want to give them the option of only printing DIV 1, omitting 2 and 3.
However, on the same page, I would like to give them the option to ONLY PRINT DIV 2. Or only print DIV 3.
I think I get how you can omit certain things from getting printed. But how can you select a section here or there on the same page to be printed with a print link.
Thanks,
Tracy
You can use jQuery to show/hide divs. Read the jQuery tutorial:
http://docs.jquery.com/Tutorials
The code will look this way:
<script>
function showDiv(n) {
$('.divs').hide();
$('#div_'+n).show();
}
$(document).ready(function() { showDiv(1); });
</script>
<a href='javascript:showDiv(n)'>show div n</a>
<div class='divs' id='div_n'>I'm div n</div>
There are many related posts on printing div content, this particular question was still open though it was asked in '10.. Following JavaScript function can be used for printing content of a selected Div tag. Hope this helps. Declaimer: I used some of the existing answers, fixed/enhanced code/error(s) to work with (and tested on) IE-8.
function printDiv(divName) {
var divToPrint = document.getElementById(divName);
var newWin = window.open('', 'PrintWindow', 'width=400, height=400, top=100, left=100', '');
newWin.document.open();
newWin.document.write('<html><body onload="window.print()">' + divToPrint.innerHTML + '</body></html>');
newWin.document.close();
setTimeout(function () { newWin.close(); }, 10);
}
Call printDiv from anywhere in page or from within selected Div. Here is test link:
Print Customer Data
Print Order Data
Assign respective IDs to Div that is to be printed:
<div id="divCustomerData">Div Contents goes here... </div>
The only catch right now is it loses css styles. I'll update response when i get a chance to fix it. Thanks.

I would give each div an id, and then using the above plugin (i wrote) specify according to div id.

There's an img element being created somehow on this page that I can't figure out how to target. It's generated by a script I don't have access to so I can't just delete it.
There are no ID or class attributed to it so I can't apply CSS (that I know of). The source link also changes for other article pages so I can't reference the URL either.
Is there anyway I can target or just hide it? It's creating extra white space at the bottom of the page.

There are two ways depending upon the possibilities on your website.
1: I suppose there will be no img tag directly inside the body tag if you code properly and put it inside a div or any other tag. So, for this solution is:
body > img {display: none;}
2: If first is not the case and the image will always come after the script tag. Then this also is the solution:
body > script + img {display: none;}
BTW, both are working in your situation.
Right click on the page and view source. You can see the element present int the page source. Delete it in the source code in line 551.
If the image src attribute is guaranteed to be consistent over time, then you can target it by that attribute, and remove it.
document
.querySelector('img[src="/support/solutions/articles/27000068245-payment-methods/hit"]')
.remove()
Here is a JS solution to target the last class in the page before all those JS src CDNs... As it seems the IMG tag is after a bunch of JS tags with the very last element in your page being the layout class, so we create a helper function that gets the siblings of the target element, then we loop over the array returned by the function and set an index, then check the tag.tagName === 'IMG' and check our iterated index => i is higher than the set index, if we get a match, remove that element from the DOM.
const removeImg = document.querySelector('.layout')
const body = document.body
function getAllSiblings(element, parent) {
const children = [...parent.children];
return children.filter(child => child !== element);
}
function removeImageAfterElement(el) {
let index = 0;
getAllSiblings(removeImg, body).forEach((tag, i) => {
tag.classList.contains(el) ? index = i : null
tag.tagName === "IMG" && i > index ? tag.remove() : null
})
}
removeImageAfterElement(removeImg)
<body>
<div class="another-class"></div>
<div class="layout layout--anonymous">

I have a lot of divs, they are the same but the data are differen(I use variable(array of objs) and for loop) but these details aren't important
<div class="item_wrapper">
<div class="item_wrapper_info">
<div class="left-line"></div>
<div class="subject">1</div> <== click here
</div>
<div class="additional_info"> <== display this block
some text
</div>
</div>
I want to achieve this:
If I click .item_wrapper_info div then I want to show .additional_info div
It should be probably done using this keyword.
If I click . item_wrapper_info block I want to find a div with the class name of . additional_info and make display = flex but I don't know how to trigger exactly its . additional_info div.
Probably I can click on .item_wrapper_info > . subject and then show its next neighbour
SOLUTION:
$(document).ready(() => {
$(".item_wrapper").click(function(){
var index = $(".item_wrapper").index(this); get index of a certain clicked .item_wrapper element on my page
$('.additional_info').eq(index).toggle(); using .eq toggle that certain element
});
})
It works for me
I haven't tested this code. Feel free to test it in a runnable snippet.
$(document).ready(() => {
$(".item_wrapper").click(function () {
var index = $(".item_wrapper").index(this)
$('.additional_info').eq(index).css("display","flex");
});
});
I have a button in my page
<button onclick="document.getElementById('donation').style.visibility='visible'">Support</button>
That I want to have linked to making a hidden div (donation) visible. I'm not sure if the getElementById works with divs, but I couldn't find out either, because when I changed the Id to h1, with a simple color change for style, it didn't work either.
Is there a problem with my button or syntax?
You can still work this with an inline onclick.
Andrei is correct about the id needing to be an individual.
<button onclick="document.getElementById('donation').style.visibility='visible'">Support</button>
<div style="background-color: gray; width: 50px; height: 50px; visibility: hidden;" id="donation"></div>
Technically though, it's better to keep your css and javascript in the head tag or outside of the html.
In order for document.getElementById('donation') to return a DOM element this condition would need to be true
there should be one html element and only one with id="donation" in your page. For example: <div id="donation"></div>
It's possible that your function works flawlessly (you can easily tell if it is by looking at your browser console after you pushed the button) but your element would still remain not visible. For example, if its display property is set to none. There are many possible reasons why an element might not be rendered by the browser. The fastest way to pinpoint the reason would be for you to create a minimal, complete and verifiable example (using the <> button) where we could experience the issue.
For me, I think separating the codes will keep things clearer and readable.
<button id="donation_btn">Support</button>
The javascript
function enableDonation( button, donationElement ) {
// check if the button is defined
if ( button != undefined
&& button != null ) {
button.addEventListener( "click", function () {
donationElement.style.display = "block";
});
}
// execute the code on document load
window.addEventListener( "load", function () {
enableDonation(
document.getElementById( "donation_btn" ),
document.getElementById( "donation" )
);
});
I'm noot good in english, so the title may seem a bit odd.
I want to use css function attr() like this:
I mean i have a container <div> and an inner <div> that i want to have width depending on data-width attribute. For example this would be great, but this doesnt work:
<div class="container">
<div data-width="70%">
</div
</div>
.container {
width: 600px;
height: 200px;
}
.container div {
width: attr(data-width);
height: 100%;
}
Is there any noJS way to use attributes like that?
UPDATE: Guys convinced me that the JS is the only way to do this :)
That's not a big problem (but that's bad. CSS, why youre so illogical? Is the difference between content:attr(data-width) and width: attr(data-width) so big ?).
One of the guys had an idea to go through the all elements with jQuery.
That's ok, but it is very... local? Don't know how to say it in english.
Anyway, i remaked his code a little bit and here it is:
allowed = ['width','color','float'];
$(document).ready(function () {
$('div').each(function (i, el) {
var data = $(el).data(),style = '';
if (!$.isEmptyObject(data)) {
$.each(data, function (attr, value) {
if (allowed.indexOf(attr) != - 1) {
style += attr + ': ' + value + '; ';
}
})
if (style.length != 0) {
$(el).attr('style', style);
}
}
})
})
Idea is simple:
1. We suppose that style we want to add to an element is the only one. I mean there are no scripts that will try to add some other styles,
2. We create an array of allowed attribute names, we need to avoid using wrong names at the style attribute, for example style="answerid: 30671428;",
3. We go through each element, save its data attributes in an object, check if object is empty, and if not - check every attribute if it is allowed, create a string that contains all styles that we need, and - finally - add our style string to the element as the content of style attribute.
That's all, thanks everybody
I would not advise to use CSS alone since it will not allow you to do what you're looking for... instead use a scripting language (in my case jQuery) to accomplish this functionality for you like so: jsFiddle
jQuery
jQuery(document).ready(function(){
var dataElem; // to store each data attribute we come accross
jQuery('div').each(function(){ //loop through each div (can be changed to a class preferably)
dataElem = jQuery(this); //get the current div
if(dataElem.data('width')){ //make sure it exists before anything further
dataElem.width(dataElem.data('width')); //set the element's width to the data attribute's value
dataElem.css("background-color", "yellow");
}
});
});
HTML
<p>The links with a data-width attribute gets a yellow background:</p>
<div>
w3schools.com
</div>
<div class="me" data-width="50"> <!-- change value to see the difference -->
disney.com
</div>
<div>
wikipedia.org
</div>
Notes on the above:
each, data, width.
Instead of doing data-width, use a class attribute. An html tag can have mutliple classes separated by spaces, so if you wanted to be very precise, you could set up as many classes as you need. For instance:
<div class="w70 h100">
</div>
Then in your css:
.w70{
width: 70%;
}
.h100{
height: 100%;
}
And so on.
Is there any noJS way to use attributes like that?
No, you cannot use CSS to set the width of the element to it's data-width attribute. CSS does not allow for this as attr() is only currently available for the CSS content property which is only available on css pseudo elements (::before and ::after).
How can you achieve this with as little javascript as possible?
This is extremely easy to do using the native host provided DOM API.
Select the elements using Document.querySelectorAll().
Iterate the elements and apply the styles using Element.style which can be retrieved from the data-width attribute using Element.dataset
(Demo)
var items = document.querySelectorAll('#container div'), item, i;
for(i = 0; (item = items[i]); i++) item.style.width = item.dataset.width;
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.
