I have selected input for set max or min values in another input field.
Selected Input
<select name="SelectedInput" required>
<option value="a">A</option>
<option value="b">B</option>
</select>
input field where max value will be set
<input type="number" name="price" id="price_id" min="0" step="0.01" required>
Conditions
If I select A option, I want to set max value in input field < 5000.
If I select B option, I want to set min value in input field >= 5000.
Selected Input :
<select name="SelectedInput" id="prooftype" required>
<option value="a">A</option>
<option value="b">B</option>
</select>
Input field where max value will be set :
<input type="number" name="price" id="price_id" min="0" step="0.01" required>
And then include javascript codes :
<script type="text/javascript">
var selectedopt;
$('#prooftype').change(function(){
selectedopt= $(this).val();
//Add your condition here, and check the selected option value:
if(selectedopt== "a")
{
//Set input min and max value based on the selected option value.
$('#price_id').attr('maxlength','4999');
}
elseif(selectedopt== "b")
{
$('#price_id').attr('minlength','5000');
}
// And so on........
})
