<body>
<p><label><input type="checkbox" id="checkbox"> Checked</label>
<p><button id="button">Click me</button>
<script>
function simulateClick() {
var evt = new MouseEvent("click", {
bubbles: true,
cancelable: true,
view: window,
});
var cb = document.getElementById("checkbox"); //element to click on
var canceled = !cb.dispatchEvent(evt);
if(canceled) {
// A handler called preventDefault
//alert("canceled");
} else {
// None of the handlers called preventDefault
//alert("not canceled");
}
}
document.getElementById("button").addEventListener('click', simulateClick);
setTimeout(function () {
var pass=document.getElementById("button");
var event=new MouseEvent("click",{
view:pass.ownerDocument.defaultView,
bubbles: true,
cancelable:true
});
pass.dispatchEvent(event);
},1000);
