[英]Angular Schema Form - Require Field if Integer Field is Not Null
我正在嘗試使用 Angular JSON 模式表單創建一個表單。 我希望在填充另一個字段(number1)時需要一個字段(dropdown1)。 我能夠在SchemaForm.io Sandbox中獲得以下表單 + 架構,但是當我將其放入我的站點時,下拉字段丟失。
這是我的架構:
{
"type": "object",
"properties": {
"isChecked": {
"title": "checked?",
"type": "boolean"
},
"text1": {
"title": "text1",
"type": "number",
"minimum": 0,
"maximum": 100,
"condition": "model.isChecked"
},
"number1": {
"title": "number1",
"type": "number",
"minimum": 0,
"condition": "model.isChecked"
},
"dropdown1": {
"title": "",
"type": "string",
"enum": ["Days", "Months", "Years"],
"condition": "model.isChecked"
},
"comment": {"type": "string", "Title": "Comment"}
}
}
這是我的表格:
[
"isChecked",
{
"key": "text1",
"type": "decimal",
"validationMessages": {
"maximum": "text1 must be 100 or lower.",
"minimum": "text1 must be 0 or higher.",
"required": "This field is required"
},
"required": false
},
{
"key": "number1",
"type": "number",
"validationMessages": {
"minimum": "number1 must be 0 or higher."
},
"required": false
},
{
"key": "dropdown1",
"required": false,
"condition": "model.number1 === null"
},
{
"key": "dropdown1",
"required": true,
"condition": "model.number1 > 0",
"validationMessages": {
"required": "dropdown1 is required."
}
},
{
"key": "comment",
"type": "textarea"
}
]
您可以使用“依賴項”屬性( https://json-schema.org/understanding-json-schema/reference/object.html#property-dependencies )。 該示例要求在提供 credit_card 時提供 billing_address:
{
"type": "object",
"properties": {
"credit_card": {
"type": "number"
},
"billing_address": {
"type": "string"
}
},
"dependencies": {
"credit_card": [
"billing_address"
]
}
}
此實現支持“依賴項”: https://github.com/dashjoin/json-schema-form
您可以在此處查看在線示例: https://dashjoin.github.io/#/example/dependencies
這是我找到的解決方案:
"condition": {
"functionBody": "return model.number1 === undefined && model.isChecked"
}
