Input 输入框

通过鼠标或键盘输入字符

Input 为受控组件,它总会显示 Vue 绑定值

通常情况下,应当处理 input 事件,并更新组件的绑定值(或使用v-model)。否则,输入框内显示的值将不会改变。

不支持 v-model 修饰符。

基础用法

Input 输入框 - 图1

  1. <el-input v-model="input" placeholder="请输入内容"></el-input>
  2. <script>
  3. import { defineComponent, ref } from 'vue'
  4. export default defineComponent ({
  5. setup() {
  6. return {
  7. input: ref('')
  8. }
  9. }
  10. })
  11. </script>

禁用状态

Input 输入框 - 图2

通过 disabled 属性指定是否禁用 input 组件

  1. <el-input
  2. placeholder="请输入内容"
  3. v-model="input"
  4. :disabled="true">
  5. </el-input>
  6. <script>
  7. import { defineComponent, ref } from 'vue'
  8. export default defineComponent ({
  9. setup() {
  10. return {
  11. input: ref('')
  12. }
  13. }
  14. })
  15. </script>

可清空

Input 输入框 - 图3

使用clearable属性即可得到一个可清空的输入框

  1. <el-input
  2. placeholder="请输入内容"
  3. v-model="input"
  4. clearable>
  5. </el-input>
  6. <script>
  7. import { defineComponent, ref } from 'vue'
  8. export default defineComponent ({
  9. setup() {
  10. return {
  11. input: ref('')
  12. }
  13. }
  14. })
  15. </script>

密码框

Input 输入框 - 图4

使用show-password属性即可得到一个可切换显示隐藏的密码框

  1. <el-input placeholder="请输入密码" v-model="input" show-password></el-input>
  2. <script>
  3. import { defineComponent, ref } from 'vue'
  4. export default defineComponent ({
  5. setup() {
  6. return {
  7. input: ref('')
  8. }
  9. }
  10. })
  11. </script>

带 icon 的输入框

带有图标标记输入类型

Input 输入框 - 图5

可以通过 prefix-iconsuffix-icon 属性在 input 组件首部和尾部增加显示图标,也可以通过 slot 来放置图标。

  1. <div class="demo-input-suffix">
  2. 属性方式:
  3. <el-input
  4. placeholder="请选择日期"
  5. suffix-icon="el-icon-date"
  6. v-model="input1">
  7. </el-input>
  8. <el-input
  9. placeholder="请输入内容"
  10. prefix-icon="el-icon-search"
  11. v-model="input2">
  12. </el-input>
  13. </div>
  14. <div class="demo-input-suffix">
  15. slot 方式:
  16. <el-input
  17. placeholder="请选择日期"
  18. v-model="input3">
  19. <template #suffix>
  20. <i class="el-input__icon el-icon-date"></i>
  21. </template>
  22. </el-input>
  23. <el-input
  24. placeholder="请输入内容"
  25. v-model="input4">
  26. <template #prefix>
  27. <i class="el-input__icon el-icon-search"></i>
  28. </template>
  29. </el-input>
  30. </div>
  31. <style>
  32. .demo-input-label {
  33. display: inline-block;
  34. width: 130px;
  35. }
  36. </style>
  37. <script>
  38. import { defineComponent, ref } from 'vue'
  39. export default defineComponent ({
  40. setup() {
  41. return {
  42. input1: ref(''),
  43. input2: ref(''),
  44. input3: ref(''),
  45. input4: ref('')
  46. }
  47. }
  48. })
  49. </script>

文本域

用于输入多行文本信息,通过将 type 属性的值指定为 textarea。

Input 输入框 - 图6

文本域高度可通过 rows 属性控制

  1. <el-input
  2. type="textarea"
  3. :rows="2"
  4. placeholder="请输入内容"
  5. v-model="textarea">
  6. </el-input>
  7. <script>
  8. import { defineComponent, ref } from 'vue'
  9. export default defineComponent ({
  10. setup() {
  11. return {
  12. textarea: ref('')
  13. }
  14. }
  15. })
  16. </script>

可自适应文本高度的文本域

通过设置 autosize 属性可以使得文本域的高度能够根据文本内容自动进行调整,并且 autosize 还可以设定为一个对象,指定最小行数和最大行数。

Input 输入框 - 图7

  1. <el-input
  2. type="textarea"
  3. autosize
  4. placeholder="请输入内容"
  5. v-model="textarea1">
  6. </el-input>
  7. <div style="margin: 20px 0;"></div>
  8. <el-input
  9. type="textarea"
  10. :autosize="{ minRows: 2, maxRows: 4}"
  11. placeholder="请输入内容"
  12. v-model="textarea2">
  13. </el-input>
  14. <script>
  15. import { defineComponent, ref } from 'vue'
  16. export default defineComponent ({
  17. setup() {
  18. return {
  19. textarea1: ref(''),
  20. textarea2: ref('')
  21. }
  22. }
  23. })
  24. </script>

复合型输入框

可前置或后置元素,一般为标签或按钮

Input 输入框 - 图8

可通过 slot 来指定在 input 中前置或者后置内容。

  1. <div>
  2. <el-input placeholder="请输入内容" v-model="input1">
  3. <template #prepend>Http://</template>
  4. </el-input>
  5. </div>
  6. <div style="margin-top: 15px">
  7. <el-input placeholder="请输入内容" v-model="input2">
  8. <template #append>.com</template>
  9. </el-input>
  10. </div>
  11. <div style="margin-top: 15px">
  12. <el-input
  13. placeholder="请输入内容"
  14. v-model="input3"
  15. class="input-with-select"
  16. >
  17. <template #prepend>
  18. <el-select v-model="select" placeholder="请选择">
  19. <el-option label="餐厅名" value="1"></el-option>
  20. <el-option label="订单号" value="2"></el-option>
  21. <el-option label="用户电话" value="3"></el-option>
  22. </el-select>
  23. </template>
  24. <template #append>
  25. <el-button icon="el-icon-search"></el-button>
  26. </template>
  27. </el-input>
  28. </div>
  29. <style>
  30. .el-select .el-input {
  31. width: 130px;
  32. }
  33. .input-with-select .el-input-group__prepend {
  34. background-color: #fff;
  35. }
  36. </style>
  37. <script>
  38. import { defineComponent, ref } from 'vue'
  39. export default defineComponent ({
  40. setup() {
  41. return {
  42. input1: ref(''),
  43. input2: ref(''),
  44. input3: ref(''),
  45. select: ref('')
  46. }
  47. }
  48. })
  49. </script>

尺寸

Input 输入框 - 图9

可通过 size 属性指定输入框的尺寸,除了默认的大小外,还提供了 large、small 和 mini 三种尺寸。

  1. <div class="demo-input-size">
  2. <el-input
  3. placeholder="请输入内容"
  4. suffix-icon="el-icon-date"
  5. v-model="input1">
  6. </el-input>
  7. <el-input
  8. size="medium"
  9. placeholder="请输入内容"
  10. suffix-icon="el-icon-date"
  11. v-model="input2">
  12. </el-input>
  13. <el-input
  14. size="small"
  15. placeholder="请输入内容"
  16. suffix-icon="el-icon-date"
  17. v-model="input3">
  18. </el-input>
  19. <el-input
  20. size="mini"
  21. placeholder="请输入内容"
  22. suffix-icon="el-icon-date"
  23. v-model="input4">
  24. </el-input>
  25. </div>
  26. <script>
  27. import { defineComponent, ref } from 'vue'
  28. export default defineComponent ({
  29. setup() {
  30. return {
  31. input1: ref(''),
  32. input2: ref(''),
  33. input3: ref(''),
  34. input4: ref('')
  35. }
  36. }
  37. })
  38. </script>

带输入建议

根据输入内容提供对应的输入建议

Input 输入框 - 图10

autocomplete 是一个可带输入建议的输入框组件,fetch-suggestions 是一个返回输入建议的方法属性,如 querySearch(queryString, cb),在该方法中你可以在你的输入建议数据准备好时通过 cb(data) 返回到 autocomplete 组件中。

  1. <el-row class="demo-autocomplete">
  2. <el-col :span="12">
  3. <div class="sub-title">激活即列出输入建议</div>
  4. <el-autocomplete

输入长度限制

Input 输入框 - 图13

maxlengthminlength 是原生属性,用来限制输入框的字符长度,其中字符长度是用 Javascript 的字符串长度统计的。对于类型为 texttextarea 的输入框,在使用 maxlength 属性限制最大输入长度的同时,可通过设置 show-word-limit 属性来展示字数统计。

  1. <el-input
  2. type="text"
  3. placeholder="请输入内容"
  4. v-model="text"
  5. maxlength="10"
  6. show-word-limit
  7. >
  8. </el-input>
  9. <div style="margin: 20px 0;"></div>
  10. <el-input
  11. type="textarea"
  12. placeholder="请输入内容"
  13. v-model="textarea"
  14. maxlength="30"
  15. show-word-limit
  16. >
  17. </el-input>
  18. <script>
  19. import { defineComponent, ref } from 'vue'
  20. export default defineComponent ({
  21. setup() {
  22. return {
  23. text: ref(''),
  24. textarea: ref('')
  25. }
  26. }
  27. })
  28. </script>
