JavaScript opens new window blocked issue

New window open page, a very common effect, as for the code, the general first reaction is so written:

window.open (URL);

but the mainstream browser will intercept this effect (there may be too many pop-up ads in these years, if the browser does not intercept, users can not stand) in order to prevent the window from being intercepted, it is generally the use of a tag to open a new page, using the target= "_blank" attribute of the A tag, generally use the following two methods according to the situation:1. Triggered by the Click Event New window opens:----Of course you can use a tag directly on the page, this is just for the rest of the groundwork!

<href= "http://www.baidu.com/"  target= "_blank"  ></a>

You can change the button that triggered the click to:

<href= "javascript:void (0)"  target= "_blank"  ID = "Openwindow" ></ a >  

Click the event to write:

1 $ ("#openWindow"). Click (function(e) {  2     $ ( This ). attr ("href", "http://www.baidu.com/");   3 });  

in the order of event firing, the href of the A tag is modified when clicked, then the default event is triggered, then the default event of the A tag is fired, and a new page is opened. Note: If you need to open a new window, you cannot use return False,e.preventdefault () in the Click event, or the statement that interrupts the default event.  2, other situation: if there is no a tag to open the page, then we create a new a tag out, and then simulate this a-tag click eventjquery notation:

1 function Openwindow (URL) {  2      var link = $ ("<a></a>"). attr ("href", url). attr (" Target "," _blank ");   3      $ ("Body"). Append (link);   4      Link[0].click ();   5      link.remove ();   6  }

native JavaScript notation:

1 function Openwindow (URL) {  2     var link = document.createelement (' a ');   3     Link.target = "_blank";   4     link.href = url;   5     document.body.appendChild (link);   6     Link.click ();   7     document.body.removechild (link);   8 }
