I have to be able to open several new tabs by the click of a button

Hi. I have an internal Content Management System program that I am working on.
I need to be able to open multiple tabs by a click of a button.

Right now i have this:

function editAll() {
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=608', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=607', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=612', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=606', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=605', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=604', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=603', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=602', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=601', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=600', '_blank', 'toolbar=0,location=0,menubar=0');
window.open('https://mycmssite.xyz/page_templates.aspx?page_ID=599', '_blank', 'toolbar=0,location=0,menubar=0');
}

But that will only open the first URL (https://mycmssite.xyz/page_templates.aspx?page_ID=608)
And it opens it in a new window rather than a new tab. What should I do to open all of these at once in each new tab?
