//Your program can't find the function so do this.
//You can assign the button onclick as an id.
//then attach an eventListener on run time like this:
<button id="btn">Click me!</button>
var btn = document.getElementById("btn");
btn.addEventListener("click", function() {
//Do something here
}, false);<script src="https://code.jquery.com/jquery-1.9.1.js"></script>
<script src="path-para-seu-script"></script>You should put the references to the jquery scripts first.
<script src="jquery-3.5.1.js"></script>
<script type="text/javascript" src="script.js"></script><script src='jquery.js'></script>
if (typeof $ == 'undefined') {
var $ = jQuery;
}
(function($){
$(document).ready(function(){
// write code here
});
// or also you can write jquery code like this
jQuery(document).ready(function(){
// write code here
});
})(jQuery);
// This is hard error to solve
// There are some cases
// 1. Your javascript code blocks have scope problem.
// 2. You may have syntax error like forget "," before Ajax request:
$.ajax({
url: requestUrl,
headers: { "token": token } // no comma error here
...
)}
// 3. In html tag `onClick` should change to id or class:
$(document).ready(function() {
$("Some id/class name").click(function(){
// your function can execute
});
});
