Converting arraybuffer to string : Maximum call stack size exceeded

问题

This is my line of code.

        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();

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 ?

回答1:

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

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