用js取出数组对象[{"bounds":{"bottom":272,"left":82,"right":160,"top":228},"confidence":0.9984832,"inferenceTime":82.0,"preprocessTime":11.0,"text":"天气","words":"天气"},{"bounds":{"bottom":277,"left":336,"right":417,"top":225},"confidence":0.8993952,"inferenceTime":82.0,"preprocessTime":11.0,"text":"相册","words":"相册"}]的值

可以使用以下代码来取出该数组对象的值:
var arr = [{"bounds":{"bottom":272,"left":82,"right":160,"top":228},"confidence":0.9984832,"inferenceTime":82.0,"preprocessTime":11.0,"text":"天气","words":"天气"},{"bounds":{"bottom":277,"left":336,"right":417,"top":225},"confidence":0.8993952,"inferenceTime":82.0,"preprocessTime":11.0,"text":"相册","words":"相册"}];
console.log(arr[0].bounds); // 输出 {"bottom":272,"left":82,"right":160,"top":228}
console.log(arr[0].confidence); // 输出 0.9984832
console.log(arr[0].text); // 输出 "天气"
console.log(arr[1].bounds); // 输出 {"bottom":277,"left":336,"right":417,"top":225}
console.log(arr[1].confidence); // 输出 0.8993952
console.log(arr[1].text); // 输出 "相册"

用js写一个函数,[{"bounds":{"bottom":272,"left":82,"right":160,"top":228},"confidence":0.9984832,"inferenceTime":82.0,"preprocessTime":11.0,"text":"天气","words":"天气"},{"bounds":{"bottom":277,"left":336,"right":417,"top":225},"confidence":0.8993952,"inferenceTime":82.0,"preprocessTime":11.0,"text":"相册","words":"相册"}] 例如传入text的值,返回对应的bounds里的值
可以使用以下函数来实现:
```javascript
function findBounds(text, data) {
const result = data.find(obj => obj.text === text);
return result ? result.bounds : null;
}
```
该函数接受两个参数:text 和 data。text 是要查找的文本,data 是一个包含对象的数组,每个对象都有一个 bounds 属性和一个 text 属性。函数将搜索 data 数组,找到第一个文本值等于 text 的对象,并返回该对象的 bounds。如果找不到匹配的对象,则返回 null。
例如,传入下面的参数:
```javascript
const data = [{"bounds":{"bottom":272,"left":82,"right":160,"top":228},"confidence":0.9984832,"inferenceTime":82.0,"preprocessTime":11.0,"text":"天气","words":"天气"},{"bounds":{"bottom":277,"left":336,"right":417,"top":225},"confidence":0.8993952,"inferenceTime":82.0,"preprocessTime":11.0,"text":"相册","words":"相册"}];
const text = "天气";
const result = findBounds(text, data);
console.log(result); // 输出: {"bottom":272,"left":82,"right":160,"top":228}
```
该函数将返回一个对象,该对象包含 bounds 的值。
注意:这里的代码仅供参考,实际开发中可能需要添加错误处理等功能。
IndexError: index 160 is out of bounds for axis 0 with size 160
IndexError: index 160 is out of bounds for axis 0 with size 160 是一个Python报错信息,它表示在使用索引160访问一个长度为160的一维数组时发生了错误。这个错误意味着索引超出了数组的范围。
在这种情况下,我们可以推断出可能是索引值定义错误,或者数组的长度定义错误。我们需要检查一下索引是否超过了数组的长度。在这个特定的错误信息中,索引160超过了数组的长度160,因此会导致IndexError报错。
要解决这个问题,我们需要检查索引值的范围是否在数组的有效范围内。如果索引超过了数组的长度,我们需要修改索引值,确保它在有效范围内。另外,也需要确保数组的长度定义正确,与实际的数据元素个数相匹配。
