Double click function in jQuery is not working

问题

I have two span elements in a page. when I call a jquery double click function on both then the function is called only on first element. I am using the following code:

<span id="shiftTime_1">1</span>
<span id="shiftTime_2">1</span>

and jquery function is:

 $("[id^='shiftTime_']").dblclick(function() {
 alert("hello");
 });

when I double click on the element Id of shiftTime_1. then the function works fine. But when I double click on element Id of shiftTime_2 then this function does not respond.

Please help. Thanks

回答1:

try use inside $(document).ready()

$(document).ready(function(){

 $("[id^='shiftTime_']").dblclick(function() {
 alert("hello");
 });

});

Use .on if you plan to add elements dynamically (e.g. by using $( "body" ).append( "<span id='shiftTime_2'>1</span>" ); )

$( "body" ).on( "dblclick", "span", function() {
    alert( "This works also with dynamically added elements" );
} );

When I try the code, it works just fine:

Check if there is something different from your code.
