Input input box sets numerical limit

Preface

• Some requirements require limiting the input content, such as amount, and the input content must be of numeric type.

Method to realize

• Because the amount has a decimal point, you need to be able to enter the decimal point in addition to the numbers.

<el-input
  v-model="number"
  onkeyup="value=value.replace(/[^\d.]/g,'')"
/>

• If you only need to enter numbers

<el-input v-model="number" onkeyup="value=value.replace(/[^\d]/g,'')" />
