I'm trying to modify the HTML markup of a page in order to add some button using JavaScript.
Below you can find a snippet (quite long, I apologize, but I really need you to get the structure of the page) of the page I am trying to modify.
My JavaScript code is inserted by a browser extension (I can successfully add the JavaScript to the page and make it run) and the only operation it should do is to add a button into the right position.
The HTML page contains a <FORM>
with a table in it.
After some rows and cells there is a cell which contains 3 input buttons:
<input type=submit name=submit value=Set Ships>
<input type=button name=sel value=Select all onclick=alert('Not Allowed.');>
<input type=button name=desel value=Deselect all onclick=alert('Not Alloowed.');>
I would like my JavaScript code to place a fourth button just after the desel
button.
This is the code I use to add the button:
function add() {
var element = document.createElement(input);
element.setAttribute(type, button);
element.setAttribute(value, invert);
element.setAttribute(name, button3);
element.setAttribute(onclick, foo());
document.flotta.appendChild(element);
}
This code obviously places the button straight at the end of my document, just after the form (named flotta
).
I realized I cannot use the function getElementById
because the <td>
tag just before the buttons does not have an id
associated.
Thus I ask if anyone can point me to a solution to add the fourth button into the right place.
