参数说明

参数|类型|默认值|是否必填|描述 --- | --- | --- | --- | --- | regExp | RegExp | null | 否 | 用于 String.prototype.replace(regexp, replacement) replacement | String | '' | 否 | 用于 String.prototype.replace(regexp, replacement) val | String/Number | | 是 | v-model 的值

示例

Vue script

setting: {
  regExp: /^[0\D]*|\D*/g, // 匹配不属于正整数的字符
  replacement: '',
  val: '223'
}

Vue template

<pattern-input class="your-class-name"
               :regExp="setting.regExp"
               :replacement="setting.replacement"
               @input="handleInput"
               @change="handleChange"
               v-model.number="setting.val"></pattern-input>

这是一个只能输入正整数的配置，记得使用 v-molde.number，如果你想要得到 Number 类型（maxlength 最大安全值是 15）

想法

I'm not sure is it necessary to emit all the input events. Now I only emit input and change events.

And I think the RegExp settings is not good enough, it's a bit awkward. Maybe I should match what I want instead of replacing what I don't want.

When I want to limit number range, it not convenient. In this condition, maybe create a number-input will be a good solution.
