调整javascript功能以在新标签页中打开链接

Question

Is there a way of adapting the following javascript to either open the link below in a new browser tab or window?

document.getElementsByClassName("yellow")[0].click();

Link on page looks like this: <a class="yellow">Buy</a>

The javascript needs to be entered in a plugin. I can't alter the code on the page itself.

Answer 1

Maybe something like this?

JS:

url = document.getElementById("yellow").getAttribute("href");
var win = window.open(url, '_blank');
win.focus();

Answer 2

If you want to load a plug in script to achieve this, you'll want to include something like this:

var el = document.getElementsByClassName("yellow")[0];

el.onclick = function () {
    newTab(this.href);
};

function newTab(url) {
    var win = window.open(url, '_blank');
    win.focus();
}

This will add onclick listener to the element in question, and use it's href property to open that url in a new tab/window (depending on browser settings).

Pop-up blocker add-ons will probably disallow this though...
