问题:

Is there a way to click on a link on my page using JavaScript?

回答1:

document.getElementById(\'yourLinkID\').click();


回答2:

This function works in at least Firefox, and Internet Explorer. It runs any event handlers attached to the link and loads the linked page if the event handlers don\'t cancel the default action.

function clickLink(link) {
    var cancelled = false;

    if (document.createEvent) {
        var event = document.createEvent(\"MouseEvents\");
        event.initMouseEvent(\"click\", true, true, window,
            0, 0, 0, 0, 0,
            false, false, false, false,
            0, null);
        cancelled = !link.dispatchEvent(event);
    }
    else if (link.fireEvent) {
        cancelled = !link.fireEvent(\"onclick\");
    }

    if (!cancelled) {
        window.location = link.href;
    }
}

If you only want to change the current page address, you can do that by simply doing this in Javascript :

location.href = \"http://www.example.com/test\";


回答4:

Simply like that : 

<a id=\"myLink\" onclick=\"alert(\'link click\');\">LINK 1</a>
<a id=\"myLink2\" onclick=\"document.getElementById(\'myLink\').click()\">Click link 1</a>

or at page load : 

<body onload=\"document.getElementById(\'myLink\').click()\">
...
<a id=\"myLink\" onclick=\"alert(\'link click\');\">LINK 1</a>
...
</body>


回答5:

The jQuery way to click a link is

$(\'#LinkID\').click();

For mailTo link, you have to write the following code

$(\'#LinkID\')[0].click();


回答6:

You could just redirect them to another page. Actually making it literally click a link and travel to it seems unnessacary, but I don\'t know the whole story.



回答7:

Instead of clicking, can you forward to the URL that the click would go to using Javascript?

Maybe you could put something in the body onLoad to go where you want.



回答8:

For me, I managed to make it work that way. I deployed the automatic click in 5000 milliseconds and then closed the loop after 1000 milliseconds. Then there was only 1 automatic click.

<script> var myVar = setInterval(function ({document.getElementById(\"test\").click();}, 500); setInterval(function () {clearInterval(myVar)}, 1000); </script>


回答9:

Many of the above methods have been deprecated. It is now recommended to use the constructor found here

function clickAnchorTag() {
    var event = document.createEvent(\'MouseEvent\');
    event = new CustomEvent(\'click\');
    var a = document.getElementById(\'nameOfID\');
    a.dispatchEvent(event);
}

This will cause the anchor tag to be clicked, but it wont show if pop-up blockers are active so the user will need to allow pop-ups.



回答10:

You can\'t make the user\'s mouse do anything. But you have full control over what happens when an event triggers.

What you can do is do a click on body load. W3Schools has an example here.

Client Side JS function to automatically click a link when...

Here is an example where you check the value of a hidden form input, which holds an error passed down from the server.. your client side JS then checks the value of it and populates an error in another location that you specify..in this case a pop-up login modal.

var signUperror = document.getElementById(\'handleError\')

if (signUperror) {
  if(signUperror.innerHTML != \"\"){
  var clicker = function(){
    document.getElementById(\'signup\').click()
  }
  clicker()
  }
}
