如何使用 javascript 将引导开关从 ON state 更改为 OFF state

Question

how to change a bootstrap switch from OFF state to ON state using javascript.

the switch html code is below,

<input type="checkbox" class="alert-status" name="ab1" id="ab1" data-size="normal" data-on-text="OFF" data-off-text="ON" checked data-bootstrap-switch data-off-color="success" data-on-color="danger">

script code,

$('.alert-status').bootstrapSwitch('state', false);

i tried some steps way but did not get it

Answer 1

Well, it's just 'a checkbox', so have you tried (to turn it ON): $('#ab1').prop('checked', true); Use false to turn it off.

Edit: Yes this works. Go to the Bootstrap docs:https://getbootstrap.com/docs/5.1/forms/checks-radios/#switches And write in the console of your browser: document.getElementById('flexSwitchCheckDefault').checked = true; And notice the "Default switch checkbox input" is turned on.

Answer 2

You need to get the checkbox by id and then set the checked property to true or false:

document.getElementById('ab1').checked = true; - for ON state

document.getElementById('ab1').checked = false; - for OFF state

For the sake of good practice let's just wrap them into functions:

function setToOn(){
  document.getElementById('ab1').checked = true;
}

function setToOff(){
  document.getElementById('ab1').checked = false;
}

 $('.switch').bootstrapSwitch('state'); $('.switch').on('switchChange.bootstrapSwitch', function() { var check = $('.bootstrap-switch-on'); switch (check.length) { case 0: console.log('OFF', check.length) break; case 1: console.log('ON', check.length) break; default: // code block } });
