在本机反应中输入一些输入值后禁用文本输入

disable text input after entering some input value in react native

这是我正在使用的文本输入,我希望在输入 value.I 后禁用输入字段尝试使用可编辑的道具,但没有帮助。 我是 React Native 的新手,请帮忙举个例子。

<View style={editProfileStyle.textinputView}>
  <TextInput
    style={editProfileStyle.textInput}
    placeholder="Enter your Specialization"
    value={this.state.subQualification}
    onChangeText={subQualification => this.setState({ subQualification: subQualification })} 
  />
</View>

根据问题,因为该字段在具有某些值时应该被禁用:

<View style={editProfileStyle.textinputView}>
              <TextInput
                editable={this.state.subQualification.length === 0}
                style={editProfileStyle.textInput}
                placeholder="Enter your Specialization"
                value={this.state.subQualification}
                onChangeText={subQualification => this.setState({ subQualification: subQualification })} 
              />
</View>

editable 道具中使用支票

editable={this.state.subQualification.length === 0} 将在字段中没有任何内容时使字段可编辑

尝试添加状态并像这样修改您的 textInput 道具:

    state ={
    textDisable: true
  }
  render() {
    return (
      <View style={editProfileStyle.textinputView}>

      <TextInput
                style={editProfileStyle.textInput}
                placeholder="Enter your Specialization"
                value={this.state.subQualification}
                onChangeText={subQualification => this.setState({ subQualification: subQualification })}
                editable={this.state.textDisable}
                onEndEditing={() => this.setState({textDisable: false})} 
              />
      </View>
    );
  }
}

onsubmit 后输入应该被禁用。
