Example introduction to the difference between jquery's trigger and triggerHandler_jquery

Both trigger and triggerHandler simulate the occurrence of events. Use specific cases to describe the differences

Copy the code The code is as follows:

<script> <br>$( document ).ready(function() { <br> $("input[type='checkbox']").bind("click",function(){ <br>$("#test").val("www.baidu.com"); <br>} ); <br>}); <br><br>function bntClick(){ <br>$("input[type='checkbox']").trigger("click"); <br>} <br> </script>

When you click the checkbox, check the checkbox and assign input[type='text'] to www.baidu.com

When input[type='button'] is clicked, the same thing as clicking checkbox will happen

When trigger is replaced with triggerHandler, when input[type='button'] is clicked, only Assigning a value to input[type='text'] without checking the checkbox

triggerHandler prevents the default behavior of the element bound to the event
