function              window   load function                 navbar a   unbind  click                navbar a   click function                    DO SOMETHING             return false                         jQuery     I find this way easier to implement  And it has the advantage that you js  Is not inside your html but in a different file  I think that without the unbind  Both events are still active  Not sure  But in a way you only need this one event

So the above solutions make the link not work  but don t make it visible  AFAICT  that the link is no longer valid  I ve got a situation where I ve got a series of pages and want to disable  and make it obvious that it s disabled  the link that points to the current page   So   window onload   function         var topics   document getElementsByClassName  topics        for  var i   topics length-1  i  gt  -1  i--             for  var j   topics i  childNodes length-1  j  gt  -1  j--                 if  topics i  childNodes j  nodeType    1                    if  topics i  childNodes j  firstChild attributes 0  nodeValue    this n root3                        topics i  childNodes j  innerHTML   topics i  childNodes j  firstChild innerHTML                                                      This walks through the list of links  finds the one that points to the current page  the n root3 might be a local thing  but I imagine document must have something similar   and replaces the link with the link text contents   HTH

you can deactivate all links in a page with this style class   a       pointer-events none      now of course the trick is deactivate the links only when you need to  this is how to do it   use an empty A class  like this   a      then when you want to deactivate the links  do this       GetStyleClass  a   pointerEvents    none       function GetStyleClass className               for  var i 0  i lt  document styleSheets length  i                var styleSheet   document styleSheets i             var rules   styleSheet cssRules    styleSheet rules            for  var j 0  j lt rules length  j                   var rule   rules j                if  rule selectorText     className                    return rule style                                              return 0         NOTE  CSS rule names are transformed to lower case in some browsers  and this code is case sensitive  so better use lower case class names for this  to reactivate links   GetStyleClass  a   pointerEvents        check this page http   caniuse com pointer-events for information about browser compatibility  i think this is the best way to do it  but sadly IE  like always  will not allow it    i m posting this anyway  because i think this contains information that can be useful  and because some projects use a know browser  like when you are using web views on mobile devices   if you just want to deactivate ONE link  i only realize THAT was the question   i would use a function that manualy sets the url of the current page  or not  based on that condition   like the solution you accepted   this question was a LOT easier than i thought

Install this plugin for jquery and use it   http   plugins jquery com project jqueryenabledisable  It allows you to disable enable pretty much any field in the page   If you want to open a page on some condition write a java script function and call it from href  If the condition satisfied you open page otherwise just do nothing   code looks like this    lt a href  javascript  openPage     gt Click here lt  a gt   and function  function openPage     if some conditon  opener document location    http   www google com         You can also put the link in a div and set the display property of the Style attribute to none  this will hide the div  For eg     lt div id  divid  style  display none  gt   lt a href  Hiding Link    gt   lt  div gt    This will hide the link  Use a button or an image to make this div visible now by calling this function in onclick as    lt a href  Visible Link  onclick  showDiv    gt   and write the js code as   function showDiv    document getElememtById  divid   style display  block       You can also put an id tag to the html  tag  so it would be    lt a id  myATag  href  whatever  gt  lt  a gt    And get this id on your javascript by using  document getElementById  myATag   value         One of this must work for sure haha

The easiest way to disable a link is simply not to show it   Run this function whenever you want to test if your condition is met to hide the Previous button  replace if  true  with your condition    var testHideNav   function         var aTags   document getElementsByTagName  a            atl   aTags length          i       for  i   0  i  lt  atl  i              if  aTags i  innerText     Previous                 if  true       your condition to disable previous                 aTags i  style visibility    hidden                 else                   aTags i  style visibility    visible                           else if  aTags i  innerText     Next                 if  false       your condition to disable next                 aTags i  style visibility    hidden                 else                   aTags i  style visibility    visible                                      Then run testHideNav   whenever you need to make the check if your condition has changed

I had a similar need  but my motivation was to prevent the link from being double-clicked   I accomplished it using jQuery     document  ready function             myLink   on  click   doSubmit        var doSubmit   function             myLink   off  click           do things here      The HTML looks like this    lt a href  javascript  void 0    id  myLink  gt click here lt  a gt

0  you better remember that Some browsers  quot jump quot  if you have a link and  quot   quot  href  So the best way would be a custom JavaScript 1  If you after the custom JavaScript  here it is   lt a href  quot   quot  onclick  quot DoSomething    return false  quot  gt Link lt  a gt    The  quot return false quot  prevents the link from actually being followed   2  You may consider avoid using following  lt a href  quot javascript void 0   quot  onclick  quot DoSomething    quot  gt Link lt  a gt   or    lt a href  quot javascript   quot  onclick  quot DoSomething    quot  gt Link lt  a gt   Because the javascript pseudo-protocol can put the page into a waiting state in some browsers  which can have unexpected consequences  IE6 is known for it  But If you don t care about IE6  and you are testing everything - it may be a good solution  3  If you already have jQuery and bootstrap in your project  you can look into using them like so      one-click   on  quot click quot   function  e          this   addClass  disabled         where  disabled class coming form bootstrap  Qupte form bootstrap site  here   Link functionality caveat The  disabled class uses pointer-events  none to try to disable the link functionality of s  but that CSS property is not yet standardized  In addition  even in browsers that do support pointer-events  none  keyboard navigation remains unaffected  meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links  So to be safe  add a tabindex  quot -1 quot  attribute on these links  to prevent them from receiving keyboard focus  and use custom JavaScript to disable their functionality   and the custom JavaScript was shown in section 1
