【H5】新增表单事件

1. onInout 获取input内的value发生变化时触发

   <input id="test_input">
   <script>
    document.getElementById('test_input').οninput=function () {
                   console.log(this.value);
               }
   </script>

   

2. oninvalid 提交异常时报错

   <form action="">
           <input id="test_input" pattern="^(\+86)?1\d{10}$">
           <button type="submit">sub</button>
   </form>
   <script>
           document.getElementById('test_input').oninvalid=function () {
                console.log(this.value);
           }
   </script>

   

也可以通过setCustomValidity来设置默认的提示

<form action="">
        <input id="test_input" pattern="^(\+86)?1\d{10}$">
        <button type="submit">sub</button>
</form>
<script>
        document.getElementById('test_input').oninvalid=function () {
            this.setCustomValidity("请输入正确的电话号码")
        }
</script>
