javascript - ViewerJS str.replace 如何使其工作

Question

我正在查看 ViewerJS，看起来很合适，我发现的唯一问题是标题显示为 %20 而不是空格。我知道为什么，但我不知道如何解决它。

所以看起来这段代码首先起作用了。我如何在这里修复它以使其显示没有 %20。

function getPDFFileNameFromURL(url) {
var reURI = /^(?:([^:]+:)?\/\/[^\/]+)?([^?#]*)(\?[^#]*)?(#.*)?$/;
//            SCHEME      HOST         1.PATH  2.QUERY   3.REF
// Pattern to get last matching NAME.pdf
var reFilename = /[^\/?#=]+\.pdf\b(?!.*\.pdf\b)/i;
var splitURI = reURI.exec(url);
var suggestedFilename = reFilename.exec(splitURI[1]) ||
                       reFilename.exec(splitURI[2]) ||
                       reFilename.exec(splitURI[3]);
if (suggestedFilename) {
suggestedFilename = suggestedFilename[0];
if (suggestedFilename.indexOf('%') !== -1) {
  // URL-encoded %2Fpath%2Fto%2Ffile.pdf should be file.pdf
  try {
    suggestedFilename =
      reFilename.exec(decodeURIComponent(suggestedFilename))[0];
  } catch(e) { // Possible (extremely rare) errors:
    // URIError "Malformed URI", e.g. for "%AA.pdf"
    // TypeError "null has no properties", e.g. for "%2F.pdf"
  }
}
}
return suggestedFilename || 'document.pdf';
}

var x = 'Some%20string%20with%20spaces';
x = x.replace(/%20/g, ' ');
console.log(x);
