The example in this article describes how to simply simulate the trigger button click function using JS. Share it with everyone for your reference, the details are as follows: 

<html>
  <head>
    <title>usually function</title>
  </head>
  <script>
function load(){
  //下面两种方法效果是一样的
  document.getElementById("target").onclick();
  document.getElementById("target").click();
}
function test(){
  alert("test");
}
</script>
  <body onload="load()">
    <button id="target" onclick="test()">test</button>
  </body>
<html>

Remarks:

btnObj.click() actually uses a program to click the button and triggers the button's onclick() event
btnObj.onclick() simply calls the method pointed to by onclick of btnObj. It just calls the method and does not trigger the event

I hope this article will be helpful to everyone in JavaScript programming.
