启用禁用按钮并使用Javascript单击它

Question

I have a disabled button I want to click with Javascript. The following function works in Chrome but not in Firefox.
The problem with Firefox: Firefox javascript is too slow.
The button is still disabled if the code wants to click it. How to click the button when it is enabled?

function enable_and_click() {
    document.getElementById('button1').disabled=false;
    document.getElementById('button1').click();
}

Answer 1

Try the following:

document.getElementById('button1').removeAttribute('disabled');
document.getElementById('button1').click();

Update

Using jQuery, a cross browser solution would be:

var element = $('#button1');
element.removeAttr('disabled');
element.click();
