You should read up on the onclick html attribute and the window open   documentation  Below is what you want    x000D   x000D   lt a href     onclick  window open  http   www google com    myWin    scrollbars yes width 400 height 650    return false   gt 1 lt  a gt  x000D   x000D   x000D    JSFiddle  http   jsfiddle net TBcVN

Try onclick function separately it can give you access to execute your function which can be used to open up a new window  for this purpose you first need to create a javascript function there you can define it and in your anchor tag you just need to call your function   Example   function newwin                    myWindow window open  lead data php leadid 1   myWin   width 400 height 650       See how to call it from your anchor tag   lt a onclick  newwin    gt Anchor lt  a gt      Update  Visit this jsbin  http   jsbin com icUTUjI 1 edit  May be this will help you a lot to understand your problem

Fun  There are a few things to tease out here     leadID seems to be a php string  Make sure it gets printed in the right place  Also be aware of all the risks involved in passing your own strings around  like cross-site scripting and SQL injection vulnerabilities  There   s really no excuse for having Internet-facing production code not running on a solid framework  Strings in Javascript  like in PHP and usually HTML  need to be enclosed in   or   characters  Since you   re already inside both   and    you   ll want to escape whichever you choose     to escape the PHP quotes  or  amp apos  to escape the HTML quotes   lt a   gt  elements are commonly used for    hyper   links  and almost always with a href attribute to indicate their destination  like this   lt a href  http   www google com  gt Google homepage lt  a gt   You   re trying to double up on watching when the user clicks  Why  Because a standard click both activates the link  causing the browser to navigate to whatever URL  even that executes Javascript   and    triggers    the onclick event  Tip  Add a return false  to a Javascript event to suppress default behavior  Within Javascript  onclick doesn   t mean anything on its own  That   s because onclick is a property  and not a variable  There has to be a reference to some object  so it knows whose onclick we   re talking about  One such object is window  You could write  lt a href  javascript window onclick   location reload   gt Activate me to reload when anything is clicked lt  a gt   Within HTML  onclick can mean something on its own  as long as its part of an HTML tag   lt a href     onclick  location reload    return false   gt   I bet you had this in mind  Big difference between those two kinds of   assignments  The Javascript   expects something that hasn   t been run yet  You can wrap things in a function block to signal code that should be run later  if you want to specify some arguments now  like I didn   t above with reload    lt a href  javascript window onclick   function      window open            gt       Did you know you don   t even need to use Javascript to signal the browser to open a link in a new window  There   s a special target attribute for that   lt a href  http   www google com  target   blank  gt Google homepage lt  a gt     Hope those are useful
