Question

I currently making a filebrowser. If the user clicks on a link to a file a little window open and asks for options (like download and view). I ve done this using the onclick attribute. If I click on the link the javascript is executed, but after this the url specified in href opens. What I m trying to do is: If you click the link javascript get executed and forwards you eventually. But if the link gets rightclicked the "copy link location" should still be available. I m thinking of solving this by blocking the forwarding scriptside. So if the link gets rightclicked no javascript is executed and you can copy the link location. But if you left click the link the javascript is executed and the link is not opened. Is that possible with javascript, or is there any other way of achieving this behavior?

Answer 1

In order to prevent the link executing, one way is to let the "onclick" method return false.

例如:

<a href="http://..." onclick="return clickfunc()">...</a>

如果clickfunc( Returncode>>false,则点击该链接不会直接到“http://. >。

虽然你可能更喜欢处理。

<a href="http://..." id="somebutton">...</a>
<script>
document.getElementById( somebutton ).onclick = function() { 
      ... 
      else { return false; }
};
</script>

Answer 2

你必须防止你点击职能出现违约情况:

function stopDefAction(evt) {  
  evt.preventDefault();  
}

Answer 3

是的,你需要,以预先防范该活动的默认行动。你可以通过将<代码>false填入你的立体。

Answer 4

您可以用“javascript:ave(0)”文本取代“href属性”,例如:

<a href="http://..." id="somebutton">...</a>
<script>
document.getElementById( somebutton ).href="javascript:void(0)"
</script>
