javascript - How to hook one event for block with many elements -


i have markup:

<fieldset class="checkbxr full small" onclick="alert('test')">     <label for="" class="fat_label">category</label>     <input type="checkbox" name="true_checkb" id="">     <span class="dmy_checkb"></span> </fieldset>

this dummy checkbox solution. ok, need hook 1 onclick event whole fieldset. if below have 3 alerts, of elements inisde, event fires 3 times. how set fieldset , make 1 event call? thx help.

this fiddle js , css: http://jsfiddle.net/vet6y/

you need cancel event bubbling depending on clicked.... here script (in pure javascript - easier in jquery - can check if there class on event source example , cancel then). script checks if tag clicked fieldset, if not cancels bubble, if pops alert.

fiddle http://jsfiddle.net/yk3tu/2/

code:

html:

<fieldset class="checkbxr full small" onclick="javascript:dosomething()">     <label for="" class="fat_label">category</label>     <input type="checkbox" name="true_checkb" id="">     <span class="dmy_checkb"></span> </fieldset>

javascript:

function dosomething(e) {     var targ;     if (!e) var e = window.event;     if (e.target) targ = e.target;     else if (e.srcelement) targ = e.srcelement;     if (targ.nodetype == 3) // defeat safari bug         targ = targ.parentnode;     console.log(targ)     if (targ.tagname!="fieldset") {      cancelbubble(e)        } else {      domything()        } } function cancelbubble(e) {  var evt = e ? e:window.event;  if (evt.stoppropagation)    evt.stoppropagation();  if (evt.cancelbubble!=null) evt.cancelbubble = true; } function domything(){     alert("this test")  }
