[英]React final forms how to add child forms
让沙箱与工作 React 表单数组https://codesandbox.io/s/react-final-form-field-arrays-react-beatiful-dnd-as-drag-drop-forked-uz24z?file=/index.js :5933-6061
其结果是点击添加热点并生成数据树为
{
"toppings":[
],
"customers":[
{
"id":4,
"firstName":"name",
"lastName":"lastname"
},
{
"id":5,
"firstName":"Clark",
"lastName":"kent"
}
],
"hotspots":[
{
"hotspotId":6,
"positionY":"Xhostspotforcustomer1",
"positionX":"Yhostspotforcustomer1"
}
]
}
但是,当单击“添加热点”按钮(到 values.customers 数组的相同索引)时,我需要将热点添加为客户的子项,例如
{
"toppings":[
],
"customers":[
{
"id":4,
"firstName":"name",
"lastName":"lastname",
"hotspots":[
{
"hotspotId":6,
"positionY":"XhostspotforcustomerID4",
"positionX":"YhostspotforcustomerID4"
},
{
"hotspotId":7,
"positionY":"more XhostspotforcustomerID4",
"positionX":"new YhostspotforcustomerID4"
}
]
},
{
"id":5,
"firstName":"Clark",
"lastName":"kent",
"hotspots":[
{
"hotspotId":8,
"positionY":"XhostspotforcustomerID5",
"positionX":"YhostspotforcustomerID5"
}
]
}
],
}
在index.js的174行添加了Add hotspot 如何修改代码单独添加每个客户的热点?
您需要将客户字段名称与热点名称结合起来:
push(`${name}.hotspots`, /*...*/)
//...
pop(`${name}.hotspots`)
<FieldArray name={`${name}.hotspots`}>
演示: https : //codesandbox.io/s/react-final-form-field-arrays-react-beatiful-dnd-as-drag-drop-forked-wivwu?file=/index.js
结果:
{
"toppings": [],
"customers": [
{
"id": 4,
"firstName": "name",
"lastName": "lastname",
"hotspots": [
{
"hotspotId": 6,
"positionY": "Customer4-Y1",
"positionX": "Customer4-X1"
},
{
"hotspotId": 7,
"positionY": "Customer4-Y2",
"positionX": "Customer4-X2"
}
]
},
{
"id": 5,
"firstName": "Clark",
"lastName": "kent",
"hotspots": [
{
"hotspotId": 8,
"positionY": "Customer5-Y1",
"positionX": "Customer5-X1"
}
]
}
]
}
