Add style attribute using javascript on load

I'm trying to add a inline-style using JavaScript as soon as the site is loaded (can't use CSS directly due to reasons). I want all text within a table to be horizontally centered,

This is my JavaScript code so far:

window.onload = center_content();
function center_content (){
    var all_td = document.getElementsByTagName('table');
    all_td[0].style.textAlign = "center !important";
}

Edit: Code corrected so far

jsfiddle: http://jsfiddle.net/GinSan/h46mz6na/4/ (remember that I can't directly use CSS in this case)

Any help is much appreciated. No jQuery solutions please.

Hyphen-separated properties of style object should be used in camelCase when it comes to JavaScript.

Try using so:

document.getElementsByTagName('table')[0].style.textAlign = "center";

You could also use .style["text-align"] to achieve the same result.

However if you want to set the priority (i.e. !important keyword), not only the value, you could use .setProperty() method as follows:

EXAMPLE HERE

document.getElementsByTagName('table')[0].style.setProperty("text-align", "center", "important");

And one more thing, by using () at window.onload = center_content(); you're executing center_content() immediately and assigning the returned value which is undefined to window.onload.

You could either do it like window.onload = center_content; or use an anonymous function:

window.onload = function () { /* ... */ };

You cannot use - in a variable name or property. Instead use style.textAlign
