在jQuery中单击多个元素？

Question

I have:

<div id="d1">
   <div id="d2"></div>
   <div id="d3"></div>
   <div id="d4"></div>
</div>

What I want is in which ever of the above element is clicked call this function:

function clickedele(){
    alert("Ele clicked");
}

I tried these But none worked:

var mhele_1 = $('#d1');
var mhele_2 = $('#d2');
var mhele_3 = $('#d3');
var menu_ico =$('#d4');
$([menu_ico.get(0),mhele_1.get(0), mhele_2.get(0),mhele_3.get(0)]).on('click', function(){
    alert("Ele clicked");
});

or

$('#menu_ico,#d1, #d2,#d3').on()

or

$('#menu_ico').add('#d1').add('#d2').add('#d3').on()

But none worked

Answer 1

Your selector #menu_ico does not point to the element the element ids are d1 , d2 and d3 so combine the id selectors and bind click event handler.

$('#d2,#d3,#d4').on('click', function(){
    alert("Ele clicked");
});

 $('#d2,#d3,#d4').on('click', function() { alert("Ele clicked"); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="d1"> <div id="d2">a</div> <div id="d3">b</div> <div id="d4">c</div> </div>

UPDATE 1: If the elements are dynamically added then use event delegation .

// assumes `#d1` is not dynamically added,
// if yes then use any of it's ancestor present
$('#d1').on('click', '#d2,#d3,#d4', function(){
    alert("Ele clicked");
});

 $('#d1').on('click', '#d2,#d3,#d4', function(){ alert("Ele clicked"); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="d1"> <div id="d2">a</div> <div id="d3">b</div> <div id="d4">c</div> </div>

FYI : Use your code within document ready handler to run after elements are loaded or add code at the end of the page.

UPDATE 2: The better approach would be using a common class for all elements and bind the handler to that.

 $('.d').on('click', function() { alert("Ele clicked"); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="d1"> <div id="d2" class="d">a</div> <div id="d3" class="d">b</div> <div id="d4" class="d">c</div> </div> 

Answer 2

 function clickedele() { console.log('clicked'); } $('div[id^="d"]').on('click',clickedele); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="d1"> <div id="d2"></div> <div id="d3"></div> <div id="d4"></div> </div> 

use $('div[id^="d"]') to select all div with id starting with d you can use any other pattern also like $('#d1 > div[id^="d"]') to select all div with id starting with d inside d1 div.

Answer 3

 $('.common').click(clickedele) function clickedele() { alert("click from " + $(this).text()) alert("Ele clicked"); } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="d1"> <div id="d2" class="common">1</div> <div id="d3" class="common">2</div> <div id="d4" class="common">3</div> </div> 

1. Add class common to all.
2. Use class to click

 $('#d1 div').click(clickedele) function clickedele() { alert("click from " + $(this).text()) alert("Ele clicked"); } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="d1"> <div id="d2" class="common">1</div> <div id="d3" class="common">2</div> <div id="d4" class="common">3</div> </div> 

1. Use the parent as selector then add space and div meaning child of parent select like $('#d1 div')

Answer 4

HTML :

<div id="d1">
   <div id="d2" onclick="isClicked(this)">d2</div>
   <div id="d3" onclick="isClicked(this)">d3</div>
   <div id="d4" onclick="isClicked(this)">34</div>
</div>

javascript :

function isClicked(obj){
   alert(obj.id);
}

Answer 5

Event Delegation should be the way to go.

 $('#d1').on('click', clickFunc) function clickFunc(e) { alert($(e.target).text()) } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="d1"> <div id="d2">1</div> <div id="d3">2</div> <div id="d4">3</div> </div> 

Answer 6

You can give child divs a common class. Lets suppose the class name is childDiv. Then you can handle the click event of the divs.

$(".childDiv").on("click",function(){
    alert("Ele clicked");
})

Answer 7

Its better to use a loop for that:

$('#d1 > div').each(function(){
 $(this).click(function(){
    alert("Ele clicked");
 });
});
