我想验证 javascript 中的电话号码

Question

I want to validate a phone number it should contain minimum of 7 digits.

const inputText = form.phone.value.trim();
  const pattern = /^\d{7}$/;
  if (!inputText.match(pattern)) {
    alert('Phone must be minimum of 7 digits.', 'error');
    return;
  }

The above code is what i tried. But it returns error if it exceeds more than 7 digits. it validates exactly 7 digits. And could anyone explains how these patterns are written.

Answer 1

[\d]{7,}

This should do it. The {7,} means you need at least 7 characters.
