<p>With HTML5 <code>max</code> and <code>min</code>, you can only restrict the values to enter numerals. But you need to use JavaScript or jQuery to do this kind of change. One idea I have is using <code>data-</code> attributes and save the old value:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>$(function () {
  $("input").keydown(function () {
    // Save old value.
    if (!$(this).val() || (parseInt($(this).val()) &lt;= 11 &amp;&amp; parseInt($(this).val()) &gt;= 0))
    $(this).data("old", $(this).val());
  });
  $("input").keyup(function () {
    // Check correct, else revert back to old value.
    if (!$(this).val() || (parseInt($(this).val()) &lt;= 11 &amp;&amp; parseInt($(this).val()) &gt;= 0))
      ;
    else
      $(this).val($(this).data("old"));
  });
});</code></pre>

blocks|key|4463513|text|也许你可以使用"range“类型，而不是"+number”类型，因为它使用了一个滑动条，如果你想配置它来显示当前的数字，只要使用JavaScript就可以了|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4463514|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

<p>Maybe Instead of using the "number" type you could use the "range" type which would restrict the user from entering in numbers because it uses a slide bar and if you wanted to configure it to show the current number just use JavaScript</p>

<p>Again, no solution truly solved my question. But combined the knowledge, it somehow worked</p>
<p>What I wanted is a true max/min validator (supporting int/float) for my input control without fancy html5 help</p>
<p>Accepted answer of @Praveen Kumar Purushothaman worked but its hardcoded min/max in the checking condition</p>
<p>@Vincent can help me dynamically validate the input field by max/min attributes but it is not generic and only validating the integer input.</p>
<p>To combine both answer
Below code works for me</p>
<pre><code>function enforceMinMax(el){
  if(el.value != &quot;&quot;){
    if(parseFloat(el.value) &lt; parseFloat(el.min)){
      el.value = el.min;
    }
    if(parseFloat(el.value) &gt; parseFloat(el.max)){
      el.value = el.max;
    }
  }
}

$(function () {
    $(&quot;input&quot;).keydown(function () {
        enforceMinMax(this);
    });
    $(&quot;input&quot;).keyup(function () {

<p>if you still looking for the answer you can use input type="number".<br>
min max work if it set in that order:<br>
1-name<br>
2-maxlength<br>
3-size<br>
4-min<br>
5-max<br>
just copy it</p>

<pre><code>&lt;input  name="X" maxlength="3" size="2" min="1" max="100" type="number" /&gt;
</code></pre>

<p>when you enter the numbers/letters manually (using the keyboard), and submit a little message will appear in case of letters "please enter a number" in case of a number out of tha range "please select a value that is no more/less than .." </p>


<p>I have <code>type=number</code> input field and I have set <code>min</code> and <code>max</code> values for it:</p>

<pre><code>&lt;input type="number" min="0" max="23" value="14"&gt;
</code></pre>

<p>When I change the time in the rendered UI using the little arrows on the right-hand side of the input field, everything works properly - I cannot go either above 23 or below 0. However, when I enter the numbers manually (using the keyboard), then neither of the restrictions has effect.</p>

<p>Is there a way to prevent anybody from entering whatever number they want?</p>

我有type=number输入字段，并为其设置了min和max值：<input type="number" min="0" max="23" value="14">当我使用输入栏右侧的小箭头更改渲染UI中的时间时，一切都正常工作-我既不能高于23也不能低于0。但是，当我手动(使用键盘)输入数字时，这两个限制都不起作用。有没有办法防止任何人输入他们想要的数字？
