Is there away to write a one function in JQUERY whenever there is input in the fields?-CodePudding

I have the below HTML code, I want to call a function using the ID of the field whenever there is input in the input fields regardless of the input field number.

<input type="text" pattern="[0-9]*" name="code" maxlength="1" autofocus="autofocus" id="input1" />
<input type="text" pattern="[0-9]*" name="code" maxlength="1" id="input2" />
<input type="text" pattern="[0-9]*" name="code" maxlength="1" id="input3" />
<input type="text" pattern="[0-9]*" name="code" maxlength="1" id="input4" />

Instead of the below, I want to call one function for all.

$("#input1").on('input', function () {
    console.log("this is input1");
});

$("#input2").on('input', function () {
    console.log("this is input2");
});

$("#input3").on('input', function () {
    console.log("this is input3");
});
$("#input4").on('input', function () {
    console.log("this is input4");
});

You can use this selector to target all your inputs $('input[id^=input]').

input[id^=input] means that it will work with all inputs where the id of the input starts with input

$("input[id^=input]").on('input', function() {
  console.log("this is "   this.id);
});

$("input[id^=input]").on('input', function() {
  console.log("this is "   this.id);
});

<input type="text" pattern="[0-9]*" name="code" maxlength="1" id="input3"  />

Many methods. One of them is to select all the inputs and triggers the input method

$("input").on("input", function (e) {
  console.log("this is input", e.target.id);
});

<input type="text" pattern="[0-9]*" name="code" maxlength="1" autofocus="autofocus" id="input1" />
<input type="text" pattern="[0-9]*" name="code" maxlength="1" id="input2" />
<input type="text" pattern="[0-9]*" name="code" maxlength="1" id="input3" />
<input type="text" pattern="[0-9]*" name="code" maxlength="1" id="input4" />

The jQuery $() query selector function accepts multiple comma-separated selectors.

$("#input1,#input2,#input3,#input4").on('input', function () {
    console.log("this is input from input 1, 2, 3 and 4");
});
