ReactJs 在 optgroup 中显示数据
ReactJs display data in optgroup
this.props.datacat.map(singleData=>{
return Object.keys(singleData).map((key,i) =>{
if(key==='name'){
return <OptGroup label = {singleData[key]}>
}else{
return <Option key= {key} >{singleData[key]}</Option>
}
return </OptGroup>
})
})
(this.props.datacat)
的数据
[
{
"4967": "Others.",
"4968": "Sports & Beachwear > Others.",
"4969": "Lingerie & Nightwear > Others.",
"4971": "Pants & Shorts > Others.",
"name": "Women Clothes"
},
{
"4798": "Supplements > Others.",
"4802": "Men's Grooming > Others.",
"4952": "Others.",
"4953": "Medical Supplies > Others.",
"4954": "Personal Pleasure > Others.",
"4955": "Personal Care > Others.",
"4956": "Pedicure & Manicure > Others.",
"6647": "Lips > Lip Tint"
"name": "Health & Beauty"
}
]
上面的代码试图显示数据,如果键是 name 然后创建 optgroup 标签,否则它将显示所有期权价值中的数据。之后,选项值 id 即 <Option key= {key} >{singleData[key]}</Option>
应该在选项值内,要显示的文本就是该值。任何人都知道如何做到这一点:( ?
为 this.props.datacat
的每个条目创建一个 OptGroup
,然后用该条目的所有选项填充它,但键为 name
的选项除外:
this.props.datacat.map((singleData) => (
<OptGroup label={singleData["name"]}>
{Object.keys(singleData)
.filter(key => key !== "name")
.map(key => (
<Option key={key}>{singleData[key]}</Option>
))}
</OptGroup>
));
this.props.datacat.map(singleData=>{
return Object.keys(singleData).map((key,i) =>{
if(key==='name'){
return <OptGroup label = {singleData[key]}>
}else{
return <Option key= {key} >{singleData[key]}</Option>
}
return </OptGroup>
})
})
