如何将click事件绑定到文档，以便仅在未单击任何对象时才触发

Question

I would like an event to fire whenever something other than a DOM element is clicked, and a separate event when an image is clicked.

Right now I have:

$( document ).click( function() { /*do whatev*/ } );

and in another place:

$( "img" ).click( function( e ) { 
  e.stopPropagation();
  /*do whatev*/
} );

it does not work. both events are fired. any other ideas?

Answer 1

Simple and concise:

jQuery(document).click(function(event) {
  if (jQuery(event.target).is('img'))
  {
    alert('img');
  }
  else
  {
    // Reject event
    return false;
  }
});

If the user clicks on an img element 'img' is alerted, otherwise the click event is stopped.

Answer 2

something like this:

$('*').click(function(ev) {
    ev.stopPropagation();
    if ($(this).is('img')) alert('img');
    else if($(this).is('div')) alert('div');
    else alert('something else');
});

This should work, but just img isn't enough. It could be triggering from the img container. I think you'd need a selector like $('p,div,img,a,input,textarea,span,ul,ol,dl,li,dd,dt,table,tr,td') and any other tag you can think of to pull it off. This might have performance issues.

Answer 4

If you want an event to fire when the html and/or body is clicked or an img is clicked something like this should work: Live Example

$(document).click(function(e) {
  if($(e.target).is('html')){
    alert('this is the html element');
  }else if($(e.target).is('body')){
    alert('this is the body element');
  }
});
$("img").click(function(e) {
    e.stopPropagation();
    alert('img')
});​
