I am working on a form widget on Elementor on WordPress, when the user submits the submit button of the form, it will show a pop-up which is created by elementor. The pop-up actually is a DIV tag including my HTML code which I wrote in an HTML widget into the pop-up, as below, and this DIV will be added by some Elementor function to the body tag of the page dynamically when user presses submit button.
<div id="calenderchooser01" style="min-height:100px;"></div>
<script>
function calenderchooser(){
var calenderhtml="";
var numofunits = document.getElementById("form-field-field_numberunits");
if(numofunits.value>=15){
calenderhtml = "<div class='calendly-inline-widget' style='min-width:320px;width:100%;height:650px;'>over 15</div>";
}else if(numofunits.value<15){
calenderhtml = "<div class='calendly-inline-widget' style='min-width:320px;width:100%;height:650px;'>less than 15</div>";
}
document.getElementById("calenderchooser01").innerHTML = calenderhtml;
console.log(calenderhtml);
}
document.getElementById("thisisanidcustom").addEventListener("click",
calenderchooser
);
</script>
thisisanidcustom is the id of submit button form. Also, I tested it with assigning showing of this pop-up to a normal button.
In both cases when I press the button it shows error on the Chrome console:
Uncaught TypeError: Cannot set property 'innerHTML' of null
at HTMLAnchorElement.calenderchooser (9a48896437a750ba11b18d8323f96ea7.js:59)
it references this line :
document.getElementById("calenderchooser01").innerHTML = calenderhtml;
and I think it says that the div#calenderchooser01 does not exist.
I think maybe the function call occurs before adding the DIV to the body tag. but I have not access to Elementor default functions to edit them and say after popup occurs call the calenderchooser(). so in this situation how can I call the function calenderchooser() right after popups shows up. I also thought of something like an event listener on DIV existing change state if available but found nothing.
this worked for me using window.setTimeout() method:
<div id="over15" class='calendly-inline-widget' style='min-width:320px;width:100%;height:650px;display:none'>over 15</div>
<div id="less15" class='calendly-inline-widget' style='min-width:320px;width:100%;height:650px;display:none'>less than 15</div>
<script>
function functionCall(){
setTimeout(calenderchooser, 100);
}
function calenderchooser(){
var numofunits = document.getElementById("form-field-field_numberunits");
if(numofunits.value>=15){
document.getElementById("over15").style.display = "block";
console.log("over15");
}else if(numofunits.value<15){
document.getElementById("less15").style.display = "block";
console.log("less15");
}
}
document.getElementById("thisisanidcustom").addEventListener("click", functionCall
);
</script>
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 trying to display a text field on clicking a link on the same page.

These does not seems to work.
How can i do it?
Thanks in advance

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>
I have a div that I am floating as a dialog over my page. When I use try and use the , the file selector does not get shown. Any help would be appreciated.
The function to create the floating div looks like
function openFloat($html)
{
$floatDiv = $('<div id="mainFloater" class="floater" ></div>');
$center = $('<div id="floaterCenter" class="floater" align="center"></div>');
$fieldset = $('<fieldset id="floaterFieldset" align="left" id="floaterFieldset"></fieldset>');
$fieldset.append($html);
$floatDiv.append($center);
$center.append($fieldset);
$('body').append($floatDiv);
}
openFloat($('<input type="file" name="file">'))
If I use the script at onload it does work.
<script type="text/javascript">
function openFloat($html)
{
$floatDiv = $('<div id="mainFloater" class="floater" ></div>');
$center = $('<div id="floaterCenter" class="floater" align="center"></div>');
$fieldset = $('<fieldset id="floaterFieldset" align="left" id="floaterFieldset"></fieldset>');
$fieldset.append($html);
$floatDiv.append($center);
$center.append($fieldset);
$('body').append($floatDiv);
}
$(document).ready(function(){
openFloat($('<input type="file" name="file">'));
});
</script>
I found the problem. I had some click handlers. A click on the mainFloater would hide everything. A click on the floaterFieldset would cancel the click (so it would not hide). However the cancel click also canceled the clicks for all buttons.
