wasm 的函数现在支持传引用类型(externref)。 (func (export "callJSFunction") (param externref) ... ) 你可以传任何 js 变量作为 externref 类型传入 wasm 函数,但该变量在 wasm 不能被读写和执行,但可以把作为返回值,或是它作为参数传给 import 进来的 js 函数。 wasm 只能对 externref 做中转,传入...
但可以修改线性内存// 然后再指定线性内存的区间让 js 去截取需要的 ArrayBuffer// 最后 ArrayBuffer 转 字符串functionconsoleLogString(offset,length){constbytes=newUint8Array(memory.buffer,offset,length);conststring=newTextDecoder('utf-8').decode(bytes);console....

Basiclly WASM is hard to debug, we still need Javascript to help, the way to do debugging is we pass Javascript Console.log function into WASM though "imports". Defined a C code: #include <math.h>voidconsoleLog (floatnum);floatgetSqrt (floatnum) { ...

Using WASM Fiddle, we show how to write a simple number logger function that calls a consoleLog function defined in JavaScript. We then download and run the same function in a local project. WASM Fiddle:https://wasdk.github.io/WasmFiddle/?cvrmt ...
