Is there a way to prevent users from entering values outside the specified max and min attributes? The constraints work when using the arrows in the input field, but not when typing directly into it.
Note: I am considering utilizing angularjs for this functionality
<input type="number" max="3" value="2" min="0" /> Perhaps instead of simply blocking intentional user input, consider providing alternative solutions to avoid confusion and frustration (such as adding feedback mechanisms like sounds or visual cues). It may be helpful to style wrong inputs using the :invalid pseudo selector.
input:invalid { background: #f00; } <input type="number" max="3" value="2" min="0" />Angular seemed like a bit much to me
Here is the HTML code snippet:
<input type="number" max="3" value="2" min="0" id="myNumInput"/>
And here is the jQuery code snippet:
$('#myNumInput').keyup(function(e) {
var $this = $(this)
var MAX_VALUE = Number($this.prop('max'))
var MIN_VALUE = Number($this.prop('min'))
var val = $this.val()
if (val.trim() === '' ||
isNaN(val) ||
Number(val) > MAX_VALUE ||
Number(val) < MIN_VALUE) {
// if the value is invalid, set it to MIN, it depends on your decision, feel free to modify the code here
$this.val(MIN_VALUE)
}
else {
// convert a string to a number format
$this.val(Number(val))
}
})
