cesium invalid array lengh
The "Invalid array length" error typically occurs in Cesium when you are trying to create an array with an invalid length. This error can occur in various situations, such as when creating a typed array or when using Cesium's APIs that expect arrays.
To resolve this issue, you should ensure that you are providing a valid length for the array. Here are a few common scenarios where this error can occur and their potential solutions:
1. Typed Arrays: If you are creating a typed array, such as `Float32Array` or `Uint16Array`, make sure that you are passing a valid length parameter. For example:
```javascript
var array = new Float32Array(10); // Valid: creates a Float32Array with a length of 10
var invalidArray = new Float32Array(-5); // Invalid: negative length
```
Ensure that the length parameter is a positive integer.
2. Array Sizes: When using Cesium's APIs that expect arrays, such as `Cesium.Matrix4.fromArray()`, make sure that the array you provide has the correct length. For example:
```javascript
var array = [1, 2, 3, 4, 5, 6];
var matrix = Cesium.Matrix4.fromArray(array); // Valid: array has the correct length of 16
var invalidArray = [1, 2, 3];
var invalidMatrix = Cesium.Matrix4.fromArray(invalidArray); // Invalid: array length is less than 16
```
Ensure that the array has the correct length as expected by the API.
3. Data Sources: If you are working with Cesium data sources, such as `Cesium.GeoJsonDataSource`, ensure that the data you provide is in the correct format and does not have any invalid lengths.
By analyzing the specific scenario where you encounter the "Invalid array length" error and ensuring that you provide valid array lengths, you should be able to resolve the issue.
Cesium提示Invalid array length是为什么
造成Invalid array length 的原因可能是因为您的数组长度超出了JavaScript数组长度限制,JavaScript的数组长度最大为2^32-1(即4294967295)。如果您的数组长度超出了这个限制,就会出现Invalid array length的提示。建议您尝试拆分数组或使用其他数据结构来实现您的需求。
