Question

I’ve a pop up window which i’m opening using below script. On every click, i want to open new pop up.
I understand, having unique name for the window will solve the problem (In this case “SampleWindow”).
What’s the best way to maintain the uniqueness of the window ? Is there any other way to manage javascript popup ?

window.open(url, 'SampleWindow', 'WIDTH=300,HEIGHT=250');

Answer 1

Passing a value of _blank to the name parameter will load the passed URL into a new window. Like this:

window.open(url, '_blank', 'width=300,height=250');

Other options for name parameter (optional) include:

• _blank – URL is loaded into a new window. This is default
• _parent – URL is loaded into the parent frame
• _self – URL replaces the current page
• _top – URL replaces any framesets that may be loaded
• name – The name of the window

Do note that if you’ll be passing this JavaScript to an anchor tag A that IE browsers expect a return value, otherwise it’ll referrence the A tag itself. Your code for that would look like:

<a href="javascript:var w=window.open(url, '_blank', 'width=300,height=250');">test</a>

or better (to avoid showing users your code in the status bar):

  <a href="javascript:void(0);" onclick="window.open(url, '_blank', 'width=300,height=250');">test</a>
