I have a html script where there is a multiple select I want to be "disabled" when I check a checkbox field.
Example:
<p><input type="checkbox" id="chk_select" name="check" value="ok" "/> deselect</p>
<p>
<select multiple="multiple" name="candidato[]" id="soci" required>
<option value="">-</option>
<option value="Name 1">Name 1</option>
<option value="Name 2">Name 2</option>
</select>
</p>
Is it possible to disable the multiple select with jquery?
Thank You! Giuseppe
Try this one.
function checkstate() {
document.getElementById('soci').disabled = document.getElementById('chk_select').checked;
}<p><input type="checkbox" id="chk_select" name="check" value="ok" onclick="checkstate()"> deselect</p>
<p>
<select multiple="multiple" name="candidato[]" id="soci" required>
<option value="">-</option>
<option value="Name 1">Name 1</option>
<option value="Name 2">Name 2</option>
</select>
</p>You can find how to check if the checkbox is checked here: Check if checkbox is checked with jQuery
Than you can find how to disable select here: jQuery - disable selected options
Try to toggle a class on the select if the checkbox is checked.
Also, you can find the working example here: disable select if checkbox is checked
This will do the trick
$('input[type="checkbox"]').change(function(){
if($(this).is(':checked')){
$('select').attr('disabled','disabled')
}else{
$('select').removeAttr('disabled','disabled')
}
})<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p><input type="checkbox" id="chk_select" name="check" value="ok" "/> deselect</p>
<p>
<select multiple="multiple" name="candidato[]" id="soci" required >
<option value="">-</option>
<option value="Name 1">Name 1</option>
<option value="Name 2">Name 2</option>
</select>
</p>Hope this helpful...
view
<p>
<input type="checkbox" id="chk_select" name="check" value="ok" onclick="myFunction()"/>
deselect
</p>
script
<script>
function myFunction() {
var checkBox = document.getElementById("myCheck");
if (checkBox.checked == true){
document.getElementById('soci').disabled = true;
} else {
document.getElementById('soci').disabled = false;
}
}
</script>
The following is a jQuery based solution, but it can just as easily be done with vanilla JS on modern browsers:
$('#chk_select').change(function(){
$('#soci').attr('disabled',this.checked);
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label><input type="checkbox" id="chk_select" name="check" value="ok"/> deselect</label>
<p> <select multiple="multiple" name="candidato[]" id="soci" required>
<option value="">-</option>
<option value="Name 1">Name 1</option>
<option value="Name 2">Name 2</option>
</select> </p>Vanilla JS solution for all browsers apart from Internet Explorer:
function qs(s){return document.querySelector(s);}
qs('#chk_select').addEventListener('change',function(){
qs('#soci').disabled=this.checked;});<label><input type="checkbox" id="chk_select" name="check" value="ok"/> deselect</label>
<p> <select multiple="multiple" name="candidato[]" id="soci" required>
<option value="">-</option>
<option value="Name 1">Name 1</option>
<option value="Name 2">Name 2</option>
</select> </p>
