私はこのようなXMLスタイリングとJSONのOBJをフェッチ動的に作成textinputsが反応-ネイティブ

Question

をから値を取得する方法：

"template": { 
"xmlui": { 
    "vbox": { 
    "hbox": { 
     "label": { 
     "@value": "", 
     "@attributes": { 
      "value": "SOME VALUE" 
     } 
     }, 
     "textField": { 
     "@value": "", 
     "@attributes": { 
      "width": "325", 
      "name": "PLAT", 
      "value": "IP", 
      "maxLength": "80", 
      "enabled": "true", 
      "interactive": "false", 
      "required": "true" 
     } 
     } 
    }, 
    "tbox": { 
     "vbox": [ 
     { 
      "label": { 
      "@value": "", 
      "@attributes": { 
       "value": "SOME MORE VALUE" 
      } 
      }, 
      "dropDownList": { 
      "item": [ 
       { 
       "@value": "", 
       "@attributes": { 
        "value": "NO", 
        "text": "NO" 
       } 
       }, 
       { 
       "@value": "", 
       "@attributes": { 
        "value": "YES", 
        "text": "YES" 
       } 
       } 
      ], 
      "@attributes": { 
       "width": "200", 
       "name": "ISP_PROIZV", 
       "value": "NO", 
       "maxLength": "8", 
       "enabled": "true", 
       "interactive": "false", 
       "required": "true" 
      } 
      } 
     }, 
... 

と私はどのようにその画面上の項目

handleMyData(keyIn, data){ 
//console.log(keyIn, typeof data, data.hasOwnProperty('@attributes'), tableItems.length); 

let fields = ['hbox', 'tbox', 'vbox']; 
if (typeof data == 'object' && data.hasOwnProperty('@attributes') && fields.indexOf(keyIn) == -1) { 
    if (keyIn == 'label') { 
    tableItems.push(
     <Text>{data['@attributes'].value}</Text> 
    ); 
    } else if (keyIn == 'textField') { 
    //this.setState({text: data['@attributes'].value}); 
    tableItems.push(
     <TextInput value={this.state.text} 
       placeholder={data['@attributes'].tip} 
       disabled={data['@attributes'].enabled == 'false'} 
       onChangeText={(text) => this.setState({text})} 
       ref= {(el) => { this.text = el; }} 
     /> 
    ); 
    } else if (keyIn == 'date') { 
    if (Platform.OS == 'ios') { 
     tableItems.push(
     <DatePickerIOS 
      date={moment(this.state.date)} 
      onDateChange={this.handleOnDateChange} 
     /> 
    ); 
    } else { 
     tableItems.push(
     <DatePicker 
      onComplete={this.handleOnDateChange} 
      enabled={data['@attributes'].enabled == 'true'} 
      value={data['@attributes'].value} 
     /> 
    ); 
    } 
} else if (keyIn == 'dropDownList') { 
    this.pickerRender(data, data['@attributes'].value); 
} 
    for (let key in data) { 
    let value = data[key]; 
    //console.log(key, value instanceof Array); 
    if (value instanceof Array) { 
    for (let i = 0; i < value.length; i++) { 
     this.handleMyData(key, value[i]); 
    } 
    } else if (typeof value === 'object' && value !== null) { 
    this.handleMyData(key, value); 
    } 
} 
}, 

pickerRender(data){ 
let pickerItems = []; 
if (data.item instanceof Array) { 
    for (let i = 0; i < data.item.length; i++) { 
    let next = data.item[i]; 
    pickerItems.push(
     <Picker.Item 
     key={'key' + i} 
     label={next['@attributes'].text} 
     value={next['@attributes'].value} 
     />); 
    } 
} else { 
    pickerItems = this.pickerPush(data); 
} 
tableItems.push(
    <Picker 
    onValueChange={(value) => this.handleOnPickerChange(value)} 
    selectedValue={this.state.pickerSelect} 
    mode="dialog" 
    >{pickerItems} 
    </Picker>); 
}, 

表示しよう私はこの要素から値を取得し、1オブジェクトに入れますか？ refキーを追加しようとしましたが、間違いをしている可能性があります。

Answer 1

pushInOpt(name, text){ 
let obj = { 
    name: name, 
    value: text 
}; 
let flag=false; 
if (options.length == 0){ 
    options.push(obj); 
}else { 
    for (let i = 0; i < options.length; i++) { 
    if (options[i].name == name) { 
     options[i].value = text; 
     flag=true; 
    } 
    } 
    if (flag==false){ 
    options.push(obj); 
    } 
} 
}, 

、onEndEditingだけのパラメータでプッシュ機能を追加して、自分でそれを決めonValueChangeなど

に
