Input in element.eleme.io

Input

Input data using mouse or keyboard.

Input is a controlled component, it always shows Vue binding value.
Under normal circumstances, input event should be handled. Its handler should update component's binding value (or use v-model). Otherwise, input box's value will not change.
Do not support v-model modifiers.

¶ Basic usage

<el-input placeholder="Please input" v-model="input"></el-input>

<script>
export default {
  data() {
    return {
      input: ''
    }
  }
}
</script>

Hide

¶ Disabled

Disable the Input with the disabled attribute.

<el-input
  placeholder="Please input"
  v-model="input"
  :disabled="true">
</el-input>

<script>
export default {
  data() {
    return {
      input: ''
    }
  }
}
</script>

¶ Clearable

Make the Input clearable with the clearable attribute.

<el-input
  placeholder="Please input"
  v-model="input"
  clearable>
</el-input>

<script>
export default {
  data() {
    return {
      input: ''
    }
  }
}
</script>

¶ Password box

Make a toggleable password Input with the show-password attribute.

<el-input placeholder="Please input password" v-model="input" show-password></el-input>

<script>
  export default {
    data() {
      return {
        input: ''
      }
    }
  }
</script>

¶ Input with icon

Add an icon to indicate input type.

Using attributes

Using slots

To add icons in Input, you can simply use prefix-icon and suffix-icon attributes. Also, the prefix and suffix named slots works as well.

<div class="demo-input-suffix">
  <span class="demo-input-label">Using attributes</span>
  <el-input
    placeholder="Pick a date"
    suffix-icon="el-icon-date"
    v-model="input1">
  </el-input>
  <el-input
    placeholder="Type something"
    prefix-icon="el-icon-search"
    v-model="input2">
  </el-input>
</div>
<div class="demo-input-suffix">
  <span class="demo-input-label">Using slots</span>
  <el-input
    placeholder="Pick a date"
    v-model="input3">
    <i slot="suffix" class="el-input__icon el-icon-date"></i>
  </el-input>
  <el-input
    placeholder="Type something"
    v-model="input4">
    <i slot="prefix" class="el-input__icon el-icon-search"></i>
  </el-input>
</div>

<style>
  .demo-input-label {
    display: inline-block;
    width: 130px;
  }
</style>

<script>
export default {
  data() {
    return {
      input1: '',
      input2: '',
      input3: '',
      input4: ''
    }
  }
}
</script>

¶ Textarea

Resizable for entering multiple lines of text information. Add attribute type="textarea" to change input into native textarea.

Control the height by setting the rows prop.

<el-input
  type="textarea"
  :rows="2"
  placeholder="Please input"
  v-model="textarea">
</el-input>

<script>
export default {
  data() {
    return {
      textarea: ''
    }
  }
}
</script>

¶ Autosize Textarea

Setting the autosize prop for a textarea type of Input makes the height to automatically adjust based on the content. An options object can be provided to autosize to specify the minimum and maximum number of lines the textarea can automatically adjust.

<el-input
  type="textarea"
  autosize
  placeholder="Please input"
  v-model="textarea1">
</el-input>
<div style="margin: 20px 0;"></div>
<el-input
  type="textarea"
  :autosize="{ minRows: 2, maxRows: 4}"
  placeholder="Please input"
  v-model="textarea2">
</el-input>

<script>
export default {
  data() {
    return {
      textarea1: '',
      textarea2: ''
    }
  }
}
</script>

¶ Mixed input

Prepend or append an element, generally a label or a button.

Http://

.com

Use slot to distribute elements that prepend or append to Input.

<div>
  <el-input placeholder="Please input" v-model="input1">
    <template slot="prepend">Http://</template>
  </el-input>
</div>
<div style="margin-top: 15px;">
  <el-input placeholder="Please input" v-model="input2">
    <template slot="append">.com</template>
  </el-input>
</div>
<div style="margin-top: 15px;">
  <el-input placeholder="Please input" v-model="input3" class="input-with-select">
    <el-select v-model="select" slot="prepend" placeholder="Select">
      <el-option label="Restaurant" value="1"></el-option>
      <el-option label="Order No." value="2"></el-option>
      <el-option label="Tel" value="3"></el-option>
    </el-select>
    <el-button slot="append" icon="el-icon-search"></el-button>
  </el-input>
</div>

<style>
  .el-select .el-input {
    width: 110px;
  }
  .input-with-select .el-input-group__prepend {
    background-color: #fff;
  }
</style>
<script>
export default {
  data() {
    return {
      input1: '',
      input2: '',
      input3: '',
      select: ''
    }
  }
}
</script>

¶ Sizes

Add size attribute to change the size of Input. In addition to the default size, there are three other options: large, small and mini.

<div class="demo-input-size">
  <el-input
    placeholder="Please Input"
    v-model="input1">
  </el-input>
  <el-input
    size="medium"
    placeholder="Please Input"
    v-model="input2">
  </el-input>
  <el-input
    size="small"
    placeholder="Please Input"
    v-model="input3">
  </el-input>
  <el-input
    size="mini"
    placeholder="Please Input"
    v-model="input4">
  </el-input>
</div>

<script>
export default {
  data() {
    return {
      input1: '',
      input2: '',
      input3: '',
      input4: ''
    }
  }
}
</script>

¶ Autocomplete

You can get some recommended tips based on the current input.

list suggestions when activated

list suggestions on input

Autocomplete component provides input suggestions. The fetch-suggestions attribute is a method that returns suggested input. In this example, querySearch(queryString, cb) returns suggestions to Autocomplete via cb(data) when suggestions are ready.

<el-row class="demo-autocomplete">
  <el-col :span="12">
    <div class="sub-title">list suggestions when activated</div>
    <el-autocomplete
      class="inline-input"
      v-model="state1"
      :fetch-suggestions="querySearch"
      placeholder="Please Input"
      @select="handleSelect"
    ></el-autocomplete>
  </el-col>
  <el-col :span="12">
    <div class="sub-title">list suggestions on input</div>
    <el-autocomplete
      class="inline-input"
      v-model="state2"
      :fetch-suggestions="querySearch"
      placeholder="Please Input"
      :trigger-on-focus="false"
      @select="handleSelect"
    ></el-autocomplete>
  </el-col>
</el-row>
<script>
  export default {
    data() {
      return {
        links: [],
        state1: '',
        state2: ''
      };
    },
    methods: {
      querySearch(queryString, cb) {
        var links = this.links;
        var results = queryString ? links.filter(this.createFilter(queryString)) : links;
        // call callback function to return suggestions
        cb(results);
      },
      createFilter(queryString) {
        return (link) => {
          return (link.value.toLowerCase().indexOf(queryString.toLowerCase()) === 0);
        };
      },
      loadAll() {
        return [
          { "value": "vue", "link": "https://github.com/vuejs/vue" },
          { "value": "element", "link": "https://github.com/ElemeFE/element" },
          { "value": "cooking", "link": "https://github.com/ElemeFE/cooking" },
          { "value": "mint-ui", "link": "https://github.com/ElemeFE/mint-ui" },
          { "value": "vuex", "link": "https://github.com/vuejs/vuex" },

         ];
      },
      handleSelect(item) {
        console.log(item);
      }
    },
    mounted() {
      this.links = this.loadAll();
    }
  }
</script>

¶ Custom template

Customize how suggestions are displayed.

Use scoped slot to customize suggestion items. In the scope, you can access the suggestion object via the item key.

<el-autocomplete
  popper-class="my-autocomplete"
  v-model="state"
  :fetch-suggestions="querySearch"
  placeholder="Please input"
  @select="handleSelect">
  <i
    class="el-icon-edit el-input__icon"
    slot="suffix"
    @click="handleIconClick">
  </i>
  <template slot-scope="{ item }">
    <div class="value">{{ item.value }}</div>
    <span class="link">{{ item.link }}</span>
  </template>
</el-autocomplete>

<style>
  .my-autocomplete {
    li {
      line-height: normal;
      padding: 7px;

      .value {
        text-overflow: ellipsis;
        overflow: hidden;
      }
      .link {
        font-size: 12px;
        color: #b4b4b4;
      }
    }
  }
</style>

<script>
  export default {
    data() {
      return {
        links: [],
        state: ''
      };
    },
    methods: {
      querySearch(queryString, cb) {
        var links = this.links;
        var results = queryString ? links.filter(this.createFilter(queryString)) : links;
        // call callback function to return suggestion objects
        cb(results);
      },
      createFilter(queryString) {
        return (link) => {
          return (link.value.toLowerCase().indexOf(queryString.toLowerCase()) === 0);
        };
      },
      loadAll() {
        return [
          { "value": "vue", "link": "https://github.com/vuejs/vue" },

          { "value": "babel", "link": "https://github.com/babel/babel" }
         ];
      },
      handleSelect(item) {
        console.log(item);
      },
      handleIconClick(ev) {
        console.log(ev);
      }
    },
    mounted() {
      this.links = this.loadAll();
    }
  }
</script>

¶ Remote search

Search data from server-side.

<el-autocomplete

        state: '',
        timeout:  null
      };
    },
    methods: {
      loadAll() {
        return [
          { "value": "vue", "link": "https://github.com/vuejs/vue" },
          { "value": "element", "link": "https://github.com/ElemeFE/element" },
          { "value": "cooking", "link": "https://github.com/ElemeFE/cooking" },

          { "value": "babel", "link": "https://github.com/babel/babel" }
         ];
      },
      querySearchAsync(queryString, cb) {
        var links = this.links;
        var results = queryString ? links.filter(this.createFilter(queryString)) : links;

        clearTimeout(this.timeout);
        this.timeout = setTimeout(() => {
          cb(results);
        }, 3000 * Math.random());
      },
      createFilter(queryString) {
        return (link) => {
          return (link.value.toLowerCase().indexOf(queryString.toLowerCase()) === 0);
        };
      },
      handleSelect(item) {
        console.log(item);
      }
    },
    mounted() {

    }
  };
</script>

¶ Limit length

0/10

0/30

maxlength and minlength are attributes of native input, they declare a limit on the number of characters a user can input. The "number of characters" is measured using JavaScript string length.Setting the maxlength prop for a text or textarea type of Input can limit the length of input value, allows you to show word count by setting show-word-limit to true at the same time.

<el-input
  type="text"
  placeholder="Please input"
  v-model="text"
  maxlength="10"
  show-word-limit
>
</el-input>
<div style="margin: 20px 0;"></div>
<el-input
  type="textarea"
  placeholder="Please input"
  v-model="textarea"
  maxlength="30"
  show-word-limit
>
</el-input>

<script>
export default {
  data() {
    return {
      text: '',
      textarea: ''
    }
  }
}
</script>
