I have unordered list of links. Using JQuery, when clicked, the link's contents (a div with image and text) are loaded into the section specified. This all works beautifully. But I'm wondering how to also get the onclick function to move the view to the div's location on the page similarly to how anchor tag works. Here is the site where you can see the div being populated, but not moving down to view it. https://www.thecompassconcerts.com/artists.php
My JQuery knowledge is not awesome (I'm being generous).
I followed Osama's suggestion to add event listener and I got almost correct results. Upon first click...contents are loaded but do not move. But on every successive click, it functions perfectly: Contents loaded and move to div (like an anchor link) works! BUT...not on Safari or Mobile Safari.
Here is my jQuery. I assume if first click is not working that I must add listener before the first click?? Can the event listeners be added on page load BEFORE the function to prevent default click, etc.?
<script>
// BEGIN FUNCTION TO CAPTURE AND INSERT CONTENT
$(document).ready(function () {
// PREVENT DEFAULT LINK ACTION
$('.bio').click(function (e) {
e.preventDefault();
// ADD LISTENER TO EACH ITEM BY CLASS
var list = document.getElementsByClassName("bio");
for (let i = 0; i < list.length; i++) {
list[i].onclick = moveToDiv;
}
// FUNCTION TO MOVE TO LOCATION
function moveToDiv() {
document.location = "#performbio";
}
// STORE the page contents
var link = $(this).attr("href");
// load the contents into #performbio div
$('#performbio').load(link);
});
});
</script>
Here is the HTML with links in unordered list
<!-- CONTRIBUTING ARTISTS LIST AND BIOS -->
<section id="artists">
<h2>Contributing Artists</h2>
<ul class="cols">
<li><a class="bio" href="performers/first-last.html">First Last</a></li>
<li><a class="bio" href="performers/first-last.html">First Last</a></li>
<li><a class="bio" href="performers/first-last.html">First Last</a></li>
</ul>
</section>
Here is HTML of Section where code is being inserted by function
<!-- Performer Bios Dynamically updated -->
<section id="performbio">
</section>
Here is div contents that are being inserted
<div class="artistbio">
<p class="artistname">First Last</p>
<img class="artistimg" src="performers/img/name.jpg">
<p>lots of text here</p>
</div>
If I understand it right, you want to scroll to the section where the details appear on clicking any item in the list but through js and not HTML. In that case, you would add an onclick listener on to the list elements like so:
listElement.onclick = moveToDiv;
The function:
function moveToDiv() {
document.location = "#performbio";
}
A simple way to add a listener to all of the elements:
var list = document.getElementsByClassName("bio");
for (let i = 0; i < list.length; i++) {
list[i].onclick = moveToDiv;
}
For the edited post, you need to move the function definition out of the document.ready function. you would change the script to:
// FUNCTION TO MOVE TO LOCATION
function moveToDiv() {
document.location = "#performbio";
}
$(document).ready(function () {
// PREVENT DEFAULT LINK ACTION
$('.bio').click(function (e) {
e.preventDefault();
// ADD LISTENER TO EACH ITEM BY CLASS
var list = document.getElementsByClassName("bio");
for (let i = 0; i < list.length; i++) {
list[i].onclick = moveToDiv;
}
// STORE the page contents
var link = $(this).attr("href");
// load the contents into #performbio div
$('#performbio').load(link);
});
});
Another Solution: Using scrollIntoView
First, get all the elements into a variable using querySelectorAll
var elements = document.querySelectorAll(".bio");
Then create a function, for the scrolling part:
function scroll(element) {
element.scrollIntoView();
}
Then just add the onclick listener:
for (let i = 0; i < elements.length; i++) {
elements[i].addEventListener('click', function() {
scroll(elements[i]);
});
}
I found it very frustrating to try to accomplish these two tasks so instead of a jQuery solution I opted for a CSS solution.
I populated my DIV with all the php includes, gave them unique id's for the anchors to work and then used CSS to hide them by default until clicked and it works like a charm....shows only what I need to show and goes there like an anchor is supposed to.
I must thank Ghost for all of your help and efforts to try and solve this via jQuery. You were very kind and generous.
Here is the code I used:
My collection of links.
<li><a class="bio" href="#artist-name1">Name 1</a></li>
<li><a class="bio" href="#artist-name2">Name 2</a></li>
which anchors to these divs
<div class="bio-container" id="artist-name1">
<?php include('performers/name-lastname.html'); ?>
</div>
<div class="bio-container" id="artist-name2">
<?php include('performers/name-lastname.html'); ?>
</div>
Then I use this CSS to hide those divs until the anchors are clicked.
I'm using [id*="artist-"] to target only links with such text...very easy. Not ideal for a massive list...but mine is not so large so it will do for this situation.
[id*="artist-"] {display: none;}
[id*="artist-"]:target {display: block;}
I'm working on a one single page navigation system; Is there is a way to change the <title> of a page when a div is :target (#divname in url)?
EDIT: Yeah, sorry, a Jquery/javascript solution works as well.
If the url contains #somePage, use #somePage as a selector and retrieve it's data-title value.
Then set <title></title> as that value. location.hash produces #somePage
$('a').click(function(event){
event.preventDefault();
if(location.hash) {
var newPageTitle = $(location.hash).data('title');
$('title').text(newPageTitle);
}
});
Add a data attribute to your div and set it's value to what the page title should be when that link is clicked.
Some Page
<div id="somePage" data-title="This Is The Page Title"></div>
It can be done in following way:
Assume that you have this html element:
<a onclick="onClick1()" href="#test">
link
</a>
and you have this scripts:
<script>
function onClick1(){
setTimeout(onClick,100);
}
function onClick(){
alert(1);
if(document.URL.indexOf("#test")>=0){
document.title = "Your title";
}
}
</script>
then you'll get on click what you need.
Here is example.
I am unable to get the click event for this HTML:
<ul id="frd_overlay_list">
<li><div class="divLink"><div id="1"><img src="path"><div class="frdName">Name</div></div></div></li>
<li><div class="divLink"><div id="2"><img src="path"><div class="frdName">Name</div></div></div></li>
</ul>
and JQuery script:
$('li').click(function(){
console.log('Not working');
});
I am able to get click event for the ul element i.e.
$('ul#frd_overlay_list').click(function(){
console.log('This works');
});
I have tried this, but this also doesnt work:
$('ul#frd_overlay_list li').click(function(){
console.log('Doesn't work either');
});
Please give me pointers what am I doing wrong?
All your example works except for the last one:
You need to escape the ' or use double quotes for the string
$('ul#frd_overlay_list li').click(function(){
console.log("Doesn't work either");
});
Since you want to apply the click events for dynamically added elements, you could use on function of jQuery.
on would bind event handlers for dynamically added elements
bind would only bind event handlers for currently existing elements.
Usage of on:
$("ul#frd_overlay_list li").on("click", function(){
console.log("Doesn't work either");
});
Fiddle
When I use the HTML <base> tag to define a base URL for all relative links on a page, anchor links also refer directly to the base URL. Is there a way to set the base URL that would still allow anchor links to refer to the currently open page?
For example, if I have a page at http://example.com/foo/:
Current behaviour:
<base href="http://example.com/" />
bar <!-- Links to "http://example.com/bar/" -->
baz <!-- Links to "http://example.com/#baz" -->
Desired behaviour:
<base href="http://example.com/" />
bar <!-- Links to "http://example.com/bar/" -->
baz <!-- Links to "http://example.com/foo/#baz" -->
I found a solution on this site: using-base-href-with-anchors that doesn't require jQuery, and here is a working snippet:
<base href="https://example.com/">
/test
Anchor
Or without inline JavaScript, something like this:
document.addEventListener('DOMContentLoaded', function(){
var es = document.getElementsByTagName('a')
for(var i=0; i<es.length; i++){
es[i].addEventListener('click', function(e) {
e.preventDefault()
document.location.hash = e.target.getAttribute('href')
})
}
})
Building upon James Tomasino's answer, this one is slightly more efficient, solves a bug with double hashes in the URL and a syntax error.
$(document).ready(function() {
var pathname = window.location.href.split('#')[0];
$('a[href^="#"]').each(function() {
var $this = $(this),
link = $this.attr('href');
$this.attr('href', pathname + link);
});
});
A little bit of jQuery could probably help you with that. Although base href is working as desired, if you want your links beginning with an anchor (#) to be totally relative, you could hijack all links, check the href property for those starting with #, and rebuild them using the current URL.
$(document).ready(function () {
var pathname = window.location.href;
$('a').each(function () {
var link = $(this).attr('href');
if (link.substr(0,1) == "#") {
$(this).attr('href', pathname + link);
}
});
}
Here's an even shorter, jQuery based version I use in a production environment, and it works well for me.
$().ready(function() {
$("a[href^='\#']").each(function() {
this.href = location.href.split("#")[0] + '#' + this.href.substr(this.href.indexOf('#')+1);
});
});
You could also provide an absolute URL:
<base href="https://example.com/">
test
Rather than this
test
I'm afraid there is no way to solve this without any server-side or browser-side script. You can try the following plain JavaScript (without jQuery) implementation:
document.addEventListener("click", function(event) {
var element = event.target;
if (element.tagName.toLowerCase() == "a" &&
element.getAttribute("href").indexOf("#") === 0) {
element.href = location.href + element.getAttribute("href");
}
});
<base href="https://example.com/">
/test
#test
It also works (unlike the other answers) for dynamically generated (i.e. created with JavaScript) a elements.
If you use PHP, you can use following function to generate anchor links:
function generateAnchorLink($anchor) {
$currentURL = "//{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";
$escaped = htmlspecialchars($currentURL, ENT_QUOTES, 'UTF-8');
return $escaped . '#' . $anchor;
}
Use it in the code like that:
baz
To prevent multiple #s in a URL:
document.addEventListener("click", function(event) {
var element = event.target;
if (element.tagName.toLowerCase() == "a" &&
element.getAttribute("href").indexOf("#") === 0) {
my_href = location.href + element.getAttribute("href");
my_href = my_href.replace(/#+/g, '#');
element.href = my_href;
}
});
My approach is to search for all links to an anchor, and prefix them with the document URL.
This only requires JavaScript on the initial page load and preserves browser features like opening links in a new tab. It also and doesn't depend on jQuery, etc.
document.addEventListener('DOMContentLoaded', function() {
// Get the current URL, removing any fragment
var documentUrl = document.location.href.replace(/#.*$/, '')
// Iterate through all links
var linkEls = document.getElementsByTagName('A')
for (var linkIndex = 0; linkIndex < linkEls.length; linkIndex++) {
var linkEl = linkEls[linkIndex]
// Ignore links that don't begin with #
if (!linkEl.getAttribute('href').match(/^#/)) {
continue;
}
// Convert to an absolute URL
linkEl.setAttribute('href', documentUrl + linkEl.getAttribute('href'))
}
})
You can use some JavaScript code inside the tag that links.
<span onclick="javascript:var mytarget=((document.location.href.indexOf('#')==-1)? document.location.href + '#destination_anchor' : document.location.href);document.location.href=mytarget;return false;" style="display:inline-block;border:1px solid;border-radius:0.3rem"
>Text of link</span>
How does it work when the user clicks?
First it checks if the anchor (#) is already present in the URL. The condition is tested before the "?" sign. This is to avoid the anchor being added twice in the URL if the user clicks again the same link, since the redirection then wouldn't work.
If there is sharp sign (#) in the existing URL, the anchor is appended to it and the result is saved in the mytarget variable. Else, keep the page URL unchanged.
Lastly, go to the (modified or unchanged) URL stored by the mytarget variable.
Instead of <span>, you can also use <div> or even <a> tags.
I would suggest avoiding <a> in order to avoid any unwanted redirection if JavaScript is disabled or not working, and emulate the look of your <a> tag with some CSS styling.
If, despite this, you want to use the <a> tag, don't forget adding return false; at the end of the JavaScript code and set the href attribute like this <a onclick="here the JavaScript code;return false;" href="javascript:return false;">...</a>.
From the example given in the question. To achieve the desired behavior, I do not see the need of using a "base" tag at all.
The page is at http://example.com/foo/
The below code will give the desired behaviour:
bar <!-- Links to "http://example.com/bar/" -->
baz <!-- Links to "http://example.com/foo/#baz" -->
The trick is to use "/" at the beginning of string href="/bar/".
If you're using Angular 2 or later (and just targeting the web), you can do this:
File component.ts
document = document; // Make document available in template
File component.html
<a [href]="document.location.pathname + '#' + anchorName">Click Here</a>
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.
