如何将arrayIndex作为参数传递给onClick中的函数？例如：
{
key:"someKey"
type:"array",
items:[
{
"key":"someKey[].itemNo"
},
{
"type":"button",
"onClick":"someFunction(someKey[arrayIndex].itemNo)"
}
]
}
arrayIndex有效。但是在函数中，undefined是我得到的。我能够在someFunction中访问整个模型或表单的数据（即我可以访问someKey），但我需要访问数组中的特定项（即someKey [index]）。

请参阅performAction按钮。我需要将按钮上下文中的电子邮件传递给函数。
形式：
[
{
"key": "comments",
"add": "New",
"style": {
"add": "btn-success"
},
"items": [
"comments[].name",
"comments[].email",
{
"key": "comments[].spam",
"type": "checkbox",
"title": "Yes I want spam.",
"condition": "model.comments[arrayIndex].email"
},
{
"key": "comments[].comment",
"type": "textarea"
},
{
"type":"button",
"onClick":"performAction(comments[arrayIndex].email)",
"title":"Perform Action"
}
]
},
{
"type": "submit",
"style": "btn-info",
"title": "OK"
}
]
架构：
{
"type": "object",
"title": "Comment",
"required": [
"comments"
],
"properties": {
"comments": {
"type": "array",
"maxItems": 2,
"items": {
"type": "object",
"properties": {
"name": {
"title": "Name",
"type": "string"
},
"email": {
"title": "Email",
"type": "string",
"pattern": "^\\S+@\\S+$",
"description": "Email will be used for evil."
},
"spam": {
"title": "Spam",
"type": "boolean",
"default": true
},
"comment": {
"title": "Comment",
"type": "string",
"maxLength": 20,
"validationMessage": "Don't be greedy!"
}
},
"required": [
"name",
"comment"
]
}
}
}
}
