如果同一类的任何文本输入中的值发生变化，如何调用函数？

Question

How to call function if another function changes the value of any text field with class netvalue.

<input name="1" type="text" class="netvalue" readonly>
<input name="2" type="text" class="netvalue" readonly>
<input name="3" type="text" class="netvalue" readonly>

<script>
$(".netvalue").oninput(function(){
       confirm('changed');   
});     
<script>

Answer 1

You can trigger an input-change.

 $(".netvalue").change(function(){ console.log('changed') }); $("#button").click(function(){ $("input[name='1']").val("some text"); $(".netvalue").trigger('change'); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button id="button">Insert text</button> <input name="1" type="text" class="netvalue" > <input name="2" type="text" class="netvalue" > <input name="3" type="text" class="netvalue" > 

Answer 2

you have to trigger the change function inside the function that is changing the value of the input.

see below

 var input = $(".netvalue"), but = $("button") $(but).on("click",function() { $(input).val("1").trigger("change") }) $(input).on("change",function() { alert("changed") }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input name="1" type="text" class="netvalue" readonly> <input name="2" type="text" class="netvalue" readonly> <input name="3" type="text" class="netvalue" readonly> <button> clickME </button>
