Question

I want to push a button programatically in javascript, just once, by pasting javascript into the address bar.

Are there any code samples that can teach me how to do this?

Answer 1

Executing JavaScript from the address bar is known as a bookmarklet. Typically you put your JavaScript between the statements javascript: and void 0. Yours would look like this:

javascript: document.getElementById("someButtonId").click(); void 0;

This will only work for an actual button. Ie, one of:

<button>Click Me</button>
<input type="button" value="Click Me" />
<input type="submit" value="Click Me" />
<input type="image" src="button.png" value="Click Me" />
