将arraybuffer转换为字符串:超出最大调用堆栈大小 [英] Converting arraybuffer to string : Maximum call stack size exceeded

问题描述

这是我的代码行.

        var xhr = new XMLHttpRequest();
        xhr.open('GET',window.location.href, true);
        xhr.responseType = "arraybuffer";
        xhr.onload = function(event) {
         debugger;
         console.log(" coverting array buffer to string "); 
         alert(String.fromCharCode.apply(null, new Uint8Array(this.response)));
        };
        xhr.send();

该请求是针对pdf网址的，该网址的大小约为3 MB.读取具有相同错误的几个线程，告诉您必须有一些递归调用，但是我在这里看不到任何递归调用.有帮助吗?

That request is making to a pdf url which is around 3 MB in size. Read few thread with same error, telling that there must be some recursive call but I do not see any recursive call here. Any help ?

推荐答案

该错误是由于函数参数数量的限制而引起的.参见"RangeError:超出最大调用堆栈大小"为什么?

The error is caused by a limitation in the number of function arguments. See "RangeError: Maximum call stack size exceeded" Why?

使用e代替String.fromCharCode.apply(). G. TextEncoder.请参见 Uint8Array以JavaScript字符串化

Instead of String.fromCharCode.apply(), use e. g. a TextEncoder. See Uint8Array to string in Javascript
