javascript - window.open is not opening a new window when used with parameters -

on clicking of hyperlink , calling below function

window.open("<%=forhyperlink%>",'name','height=600,width=800'); 

the issue , above line , 1 time hyper link click working (that if hyper link clicked , no window being opened up)

but if remove parameters window.open , use

window.open("<%=forhyperlink%>"); 

then on click of every hyperlink new window being opened.

please adivce .

change name of each window per link window opened on initial click won't re-used.

i'm guessing clicking on other links opens links on initial/currently opened pop-up , causes confusion doesn't open new windows.

// first window open window.open("first.html",'name','height=600,width=800');  // opens in same window first.html opened because  // targets same window called `name` window.open("second.html",'name','height=600,width=800');  // works because default open new 1 everytime executed window.open("new.html");  // opens window unique name  window.open("<%=forhyperlink%>",'name_' + math.random(),'height=600,width=800');
