I want to get redirect by click on button, I use:
<inputtype="submit" onclick="location.href='first';" value="goSomewhere1"/>
<inputtype="submit" onclick="location.href='second';" value="goSomewhere2"/>
and it workf if is clicked on page http://ADDRESS but if is clicked when url is like http://ADDRESS/something it redirects to http://ADDRESS/something/first
How is it possible to get redirect just before ADDRESS but not put this value (ADDRESS) because it could change? (for this example it should get http://ADRESS/first insted of http://ADDRESS/something/first)
You want /first not first.
Without a slash, it's a relative link. With the slash, it's absolute to the base URL.
<input type="submit" onclick="location.href='/first'" value="goSomewhere1"/>
<input type="submit" onclick="location.href='/second'" value="goSomewhere2"/>
I have a form link on multiple pages. All I need when I click on a form link for page A it should display as www.form.com?referrer=Page A on URL and when I submit the form, I have created a hidden field referrer, when I received it on my email on the referrer field it should show "page A".
I have this HTML code which was working fine however, I do not want to do it manually on every page, as soon as a user clicks on the form link or received the form it should automatically updated:
<a target="_blank" title="Click Here" href="https://myform.com/forms/land_discount?referrer= Beach Club">
Here is the JavaScript for my Form:
Discount Form
See if this is what you are trying to do:
// I'm going to use jQuery, it's easier for me
$(document).ready(function(){
// I used a class so it doesn't do it to every <a> tag
$('a.use_refer').click(function(e){
// Stop the button from submitting normally
e.preventDefault();
// Create a new url
// You may or may not want to use encodeURIComponent() on the path value
var newUrl = $(this).attr('href')+'?referrer='+document.location.pathname;
// Go to the new page
window.location = newUrl;
});
});
</script>
Click Here
Assuming you Page A is the last directory of the path. And wrap this for when the DOM is ready.
Note the changes to the HTML with the addition of the id= tag.
On "Page A"
HTML:
<script type="text/javascript" src="https://myform.com/forms/js.php/test"></script>
<noscript>
Game Form
</noscript>
Javascript:
var url = document.getElementById('formRef').getAttribute("href");
document.getElementById('formRef')
.setAttribute('href', encodeURI(url + '?referrer=' + window.location.href.slice(window.location.href.lastIndexOf('/') + 1)));
On "Landing Page"
HTML:
<a id="landingPage" target="_blank" title="Click Here" href="https://myform.com/forms/land_discount">
Javascript:
var href = document.getElementById('landingPage').getAttribute('href');
if(window.location.href.indexOf('referrer=') > -1){
document.getElementById('landingPage').setAttribute('href', encodeURI(href + window.location.href.slice(window.location.href.indexOf('?referrer='))));
}
I have a link that a user can share on fb and G+.
The user can modify that link and he did it with an ajax call so the page is not refreshing.
My gplus button code :
<link rel="canonical" href="{{ url }}" />
<g:plus action="share" style="height: 28px;" ></g:plus>
when the user changes the url I update the href attribute too :
$.post(url,{
someParams:"someValues"
},function(data){
.
.
.
// updating the href attribute with the new modified url
$('link[rel="canonical"]').attr("href",data.url);
}
The problem is that the G+ button still load the old url.
But only by refreshing I get the new one.
My question is how can i change the G+ url without refreshing the page ?
Is this what you want (obviously changing that prompt for your ajax callback logic)?

HTML
<!-- Place this tag where you want the +1 button to render. -->
<div id="gplus"></div>
<button>change it!</button>
JS
$(function() {
var container = $('#gplus');
var render = function(url) {
container.html('<g:plusone href="' + url + '"></g:plusone>');
gapi.plusone.go('gplus');
};
$('button').click(function(event){
var url = prompt('Give me an URL');
render(url);
});
render(location.href);
});
Be aware that I'm loading the plusone.js in the external resources of that jsfiddle.
BTW, why did you use the Symfony2 tag?
This is crazy but I don't know how to do this, and because of how common the words are, it's hard to find what I need on search engines. I'm thinking this should be an easy one to answer.
I want a simple file download, that would do the same as this:
Download!
But I want to use an HTML button, e.g. either of these:
<input type="button" value="Download!">
<button>Download!</button>
Likewise, is it possible to trigger a simple download via JavaScript?
$("#fileRequest").click(function(){ /* code to download? */ });
I'm definitely not looking for a way to create an anchor that looks like a button, use any back-end scripts, or mess with server headers or mime types.
You can trigger a download with the HTML5 download attribute.
Download
Where:
path_to_file is a path that resolves to an URL on the same origin. That means the page and the file must share the same domain, subdomain, protocol (HTTP vs. HTTPS), and port (if specified). Exceptions are blob: and data: (which always work), and file: (which never works).
proposed_file_name is the filename to save to. If it is blank, the browser defaults to the file's name.
Documentation: MDN, HTML Standard on downloading, HTML Standard on download, CanIUse
For the button you can do
<form method="get" action="file.doc">
<button type="submit">Download!</button>
</form>
HTML:
<button type="submit" onclick="window.open('file.doc')">Download!</button>
A simple JS solution:
function download(url) {
const a = document.createElement('a')
a.href = url
a.download = url.split('/').pop()
document.body.appendChild(a)
a.click()
document.body.removeChild(a)
}
With jQuery:
$("#fileRequest").click(function() {
// hope the server sets Content-Disposition: attachment!
window.location = 'file.doc';
});
You can do it with "trick" with invisible iframe. When you set "src" to it, browser reacts as if you would click a link with the same "href". As opposite to solution with form, it enables you to embed additional logic, for example activating download after timeout, when some conditions are met etc.
It is also very silient, there's no blinking new window/tab like when using window.open.
HTML:
<iframe id="invisible" style="display:none;"></iframe>
Javascript:
function download() {
var iframe = document.getElementById('invisible');
iframe.src = "file.doc";
}
Bootstrap Version
<a class="btn btn-danger" role="button" href="path_to_file"
download="proposed_file_name">
Download
</a>
Documented in Bootstrap 4 docs, and works in Bootstrap 3 as well.
I think this is the solution you were looking for
<button type="submit" onclick="window.location.href='file.doc'">Download!</button>
I hade a case where my Javascript generated a CSV file. Since there is no remote URL to download it I use the following implementation.
downloadCSV: function(data){
var MIME_TYPE = "text/csv";
var blob = new Blob([data], {type: MIME_TYPE});
window.location.href = window.URL.createObjectURL(blob);
}
You can hide the download link and make the button click it.
<button onclick="document.getElementById('link').click()">Download!</button>
<a id="link" href="file.doc" download hidden></a>
What about:
<input type="button" value="Download Now!" onclick="window.location = 'file.doc';">
In my testing the following works for all file types and browsers as long as you use a relative link:
<button>Download 2</button>
/assets/hello.txt is just a relative path on my site. Change it to your own relative path.
my_file.txt is the name you want the file to be called when it is downloaded.
Explanation
I noticed there were comments under a lot of the answers that said the browser would just try to open the file itself rather than downloading it depending on the file type. I discovered this to be true.
I made two buttons to test it out using two different methods:
<button onclick="window.location.href='/assets/hello.txt';">Download 1</button>
<button>Download 2</button>
Notes:
Button 1 opened the text file in a new browser tab. However, Button 1 would download the file for file types that it couldn't open itself (for example, .apk files).
Button 2 downloaded the text file. However, Button 2 only downloaded the file if the path was relative. When I changed the path to an absolute path, then the browser opened it in a new tab.
I tested this on Firefox, Safari, and Chrome.
Hello I just include the word 'download' and works well.
<a href="file.pdf" download>Download</a>
So in javascript you can use the follow:
function onStartedDownload(id) {
console.log(`Started downloading: ${id}`);
}
function onFailed(error) {
console.log(`Download failed: ${error}`);
}
var downloadUrl = "https://example.org/image.png";
var downloading = browser.downloads.download({
url : downloadUrl,
filename : 'my-image-again.png',
conflictAction : 'uniquify'
});
downloading.then(onStartedDownload, onFailed);
If your looking for a vanilla JavaScript (no jQuery) solution and without using the HTML5 attribute you could try this.
const download = document.getElementById("fileRequest");
download.addEventListener('click', request);
function request() {
window.location = 'document.docx';
}
.dwnld-cta {
border-radius: 15px 15px;
width: 100px;
line-height: 22px
}
<h1>Download File</h1>
<button id="fileRequest" class="dwnld-cta">Download</button>
<button>Download!</button>
This will download the file as .doc file extension is not supported to be opened in browser.
One of the simplest way for button and the text-decoration will help to alter or to remove the text decoration of the link.
Anywhere between your <body> and </body> tags, put in a button using the below code:
<button>
<a href="file.doc" download>Click to Download!</a>
</button>
This is sure to work!
all you need to do is add Download after the file name which you have entered:
Before:
Download!
After
<a href="file.doc" Download >Download!</a>
Make sure the download is written with a capital letter otherwise it's not gonna work.
This is what finally worked for me since the file to be downloaded was determined when the page is loaded.
JS to update the form's action attribute:
function setFormAction() {
document.getElementById("myDownloadButtonForm").action = //some code to get the filename;
}
Calling JS to update the form's action attribute:
<body onLoad="setFormAction();">
Form tag with the submit button:
<form method="get" id="myDownloadButtonForm" action="">
Click to open document:
<button type="submit">Open Document</button>
</form>
The following did NOT work:
<form method="get" id="myDownloadButtonForm" action="javascript:someFunctionToReturnFileName();">
If you can't use form, another approach with downloadjs fit nice. Downloadjs use blob and html 5 file API under the hood:
<div onClick=(()=>{downloadjs(url, filename)})/>
*it's jsx/react syntax, but can be used in pure html
Not really an answer to the original question but it may help others which face similar situations as myself.
If the file you want to download is not hosted on the same origin but you want to be able to download it, you can do that with the Content-Disposition header. Make sure the server includes the header when responding to requests of the file.
Setting a value like
Content-Disposition: attachment will ensure that the file will be downloaded instead of viewed in the browser.
A simple Download pointing to your file should download it in this case.
If you want
Download
for the ability to download files that would be rendered by the browser otherwise, But still want a neat javascript function to use in a button; you can have an invisible link in html and click it in javascript.
function download_file() {
document.getElementById("my_download").click()
}
<a id="my_download" href="path_to_file" download="file_name" style="display:none;"></a>
<button onClick="download_file()">Download!!!</button>
Another way of doing in case you have a complex URL such as file.doc?foo=bar&jon=doe is to add hidden field inside the form
<form method="get" action="file.doc">
<input type="hidden" name="foo" value="bar" />
<input type="hidden" name="john" value="doe" />
<button type="submit">Download Now</button>
</form>
inspired on #Cfreak answer which is not complete
The solution I have come up with is that you can use download attribute in anchor tag but it will only work if your html file is on the server. but you may have a question like while designing a simple html page how can we check that for that you can use VS code live server or bracket live server and you will see your download attribute will work but if you will try to open it simply by just double clicking html page it open the file instead of downloading it.
conclusion: attribute download in anchor tag only works if your html file is no server.
For me ading button instead of anchor text works really well.
<button>Download!</button>
It might not be ok by most rules, but it looks pretty good.
If you use the <a> tag, do not forget to use the entire url which leads to the file -- i.e.:
Download
