Feature request: refresh selection when option hidden #40
Description
When i remove options from a select list, and the selection is on one of this hidden options, the selection should be refreshed, so it is on a visible option.
Example:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="./dependsOn.min.js"></script>
</head>
<body>
<div class="field field-numbers">
<label>Number</label>
<select name="numbers">
<option>One</option>
<option>Two</option>
<option>Three</option>
</select>
</div>
<div class="field field-chars">
<label>Char</label>
<select name="chars">
<option>A</option>
<option class="depend-B">B</option>
<option>C</option>
<option>D</option>
</select>
</div>
<script>
$(function() {
function checkSelectsOptionsVisibilty(selector)
{
if ($(selector + ' option:selected').is(':disabled')) {
$(selector + ' option').each(function () {
if ($(this).css('display') != 'none') {
$(this).prop("selected", true);
return false;
}
});
}
}
$('.depend-B').dependsOn({
'.field-numbers select': {
values: ['One','Two']
}
}, {
onDisable: function() { checkSelectsOptionsVisibilty('.field-chars select');}
});
});
</script>
</body>
</html>
Select char "B", then number "three". The selection "jumps" now to char "A", because "B" is now hidden.
It would save a lot of code lines on longer forms, if the functionality of checkSelectsOptionsVisibilty() would be somehow be included in dependsOn.
