在JavaScript中一段时间​​后如何触发按钮的点击事件

Question

I tried to trigger click event of button after 3 mins using below javascript code

setTimeout(function(){$(‘._my_save_button’).trigger(‘click’)},180000);

Above code throws error when we run in chrome console

Uncaught SyntaxError: Invalid or unexpected token

Answer 1

We need to fix the quotes around your identifier.

    setTimeout(function() {
        $('._my_save_button').trigger('click');
    }, 3000);

Answer 2

I think you are only missing the right css selector.

should be "#_my_save_button" in case of id="_my_save_button" or "._my_save_button" in case of class="_my_save_button" :

setTimeout(function(){$("#_my_save_button").trigger("click")},180000);
