如何删除自动完成上的清除按钮并仅显示文本

Question

我是反应虚拟化和自动完成的新手。我目前已经建立了一个列表，当复选框被选中时，它会显示多个文本。这是我的代码： https://codesandbox.io/s/material-demo-forked-1qzd3?file=/demo.tsx

我想在从列表中选择任何内容时只显示一个文本，并删除附加的清除按钮和灰色背景。

Answer 1

有一个专门的道具来禁用图标。 在自动完成组件上尝试道具

"disableClearable"

它在文档中：

<Autocomplete
    {...defaultProps}
    id="disable-clearable"
    disableClearable
    renderInput={(params) => <TextField {...params} label="disableClearable" 
    margin="normal" />}
/>

Answer 2

从 MUIv5 开始，Autocomplete 不再在实验室中，它做的事情有点不同，并为您提供更多显示定制。清除图标和向下箭头都在传递给 renderInput 函数的 InputProps.endAdornment 中。所以你可以在传播到 TextField 之前删除它

 <Autocomplete
  options={options}
  renderInput={params => {
    const InputProps = { ...params.InputProps };
    InputProps.endAdornment = null;
    return (
      <TextField    
        {...params}
        InputProps={InputProps}
      />
    );
  }}
  openOnFocus  
  />
  

注意 InputProps 在 {...params} 传播后的情况。

如果你这样做，你需要添加“openOnFocus”道具，因为向下箭头不会在那里点击打开自动完成。

MUI 还向 .MuiInput-root 类添加了一些 paddingRight，以便为 clearIcon 和 downArrow 腾出一些空间，因此如果空间紧张，您可能需要删除它们，我最终在 TextField 类上使用了 !important css 规则，但我们仍在使用旧的 JSS 方式。不确定正确的情感造型方式是什么。

试试这个：

import React, { useState } from "react";
import Checkbox from "@material-ui/core/Checkbox";
import TextField from "@material-ui/core/TextField";
import Autocomplete from "@material-ui/lab/Autocomplete";
import CheckBoxOutlineBlankIcon from "@material-ui/icons/CheckBoxOutlineBlank";
import { ListItemText } from "@material-ui/core";
import CheckBoxIcon from "@material-ui/icons/CheckBox";
import MenuItem from "@material-ui/core/MenuItem";
import { List } from "react-virtualized";
import faker from "faker";

const icon = <CheckBoxOutlineBlankIcon fontSize="small" />;
const checkedIcon = <CheckBoxIcon fontSize="small" />;

const ListboxComponent = React.forwardRef(function ListboxComponent(
  props,
  ref
) {
  const { children, role, ...other } = props;
  const itemCount = Array.isArray(children) ? children.length : 0;
  const itemSize = 36;

  return (
    <div ref={ref}>
      <div {...other}>
        <List
          height={250}
          width={300}
          rowHeight={itemSize}
          overscanCount={5}
          rowCount={itemCount}
          rowRenderer={(props) => {
            return React.cloneElement(children[props.index], {
              style: props.style
            });
          }}
          role={role}
        />
      </div>
    </div>
  );
});

const myDAta = Array.from(new Array(10000)).map(() => {
  return { name: faker.name.findName() };
});

myDAta.unshift({ name: "ALL" });

export default function CheckboxesTags() {
  const [selectedFilm, setSelectedFilm] = useState([]);
  const onCloseHandle = () => {
    console.log("Closed");
  };
  return (
    <Autocomplete
      id="checkboxes-tags-demo"
      ListboxComponent={ListboxComponent}
      options={myDAta}
      onChange={(e, film) => {
        console.log(e.target);
        setSelectedFilm(film);
      }}
      onClose={onCloseHandle}
      getOptionLabel={(option) => option.name}
      // fullWidth
      renderOption={(option) => <>{option.name}</>}
      closeIcon=""

      style={{ width: 300, maxHeight: "1px" }}
      renderInput={(params) => (
        <TextField
          {...params}
          variant="outlined"
          label="Checkboxes"
          placeholder="Favorites"
        />
      )}
    />
  );
}

Answer 4

返回所有参数，没有

endAdornment

在

TextField

renderInput={(params) => <TextField {...params} 
InputProps={{ ...params.InputProps, endAdornment : null }}
onPaste={handlePaste} variant='outlined'/>}

Answer 5

使用 typescript 和设置

disableClearable={true}

控制 MuiAutocomplete 会导致类型检查错误（错误：值应为 T 或未定义）。

当我的受控值类型定义为 T | 时，这发生在我身上无效

在这种情况下

disableClearable={value !== null}

解决了问题

Answer 6

我在 Material UI V5 中解决了这个问题并使用

freeSolo

.

你必须添加

disableClearable={true}

到

Autocomplete

然后你应该删除

type:text

从

Textfield

.

你应该有这样的东西。

<Autocomplete
  disableClearable={true}
  freeSolo
  renderInput={(params) => (
    <TextField
      {...params}
      placeholder={placeholder}
    />
  )}
  name="input"
/>```
