如何使Javascript程序模拟鼠标单击？

Question

I want to make a JavaScript program simulate a mouse click wherever the mouse is on a timed interval. I know of the

if(mouseIsPressed) 

and the

if(mouseDown) 

commands, but are there any commands that make my mouse automatically click, some kind of forceMouseDown command maybe?

Answer 1

If you just want to click a button, as I see from the comment, than just click the specific button with HTMLElement.click() in an interval.

Like this:

 var myButton = document.getElementById('my-button'); // Just for example var clickCount = 0; var clickStatus = document.getElementById('clicks'); setInterval(function(){ myButton.click(); clickStatus.innerText = ++clickCount; }, 2000) 

 <button id="my-button">My Button</button> <p>Clicks: <span id="clicks">0</span></p> 

Answer 2

Can use elementFromPoint() to identify top most element at current mouse position.

Combine that with a mousemove listener to track mouse position in page

var mousePos ={x:0,y:0}


setInterval(function(){  
  document.elementFromPoint(mousePos.x, mousePos.y).click()
}, 2000)

document.addEventListener('mousemove', function(e){
  mousePos.x = e.clientX;
  mousePos.y = e.clientY;  
});
