Download the current release or clone the repo and upload dist/whatsapp-button.js
somewhere on your webserver.
Use this code right before the </body>
, replace http://your-domain.tld/path/whatsapp-button.js
with the url to the just uploaded file.
<script type="text/javascript"> if(typeof wabtn4fg==="undefined") {wabtn4fg=1;h=document.head||document.getElementsByTagName("head")[0],s=document.createElement("script");s.type="text/javascript";s.src="http://your-domain.tld/path/whatsapp-button.js";h.appendChild(s)}</script>
Place this code somewhere on your website to display the button:
<a href="whatsapp://send" data-text="Take a look at this awesome website:" data-href="" class="wa_btn wa_btn_s" style="display:none">Share</a>
If you want to customize the size, style, url or the sharing text, feel free to visit whatsapp-sharing.com for a code generator.
Run theWaShBtn.crBtn();
after you loaded your content.
You can simply use JavaScript event handlers like onClick
in the code of step 3.
Nope, that's not possible (at the moment).
It's not possible to check if WhatsApp is installed on the device. This is a good thing, imagine a webpage can access the list of installed applications.
