Question

任何人都可以告诉我下面列出的JSON语法有什么问题。根据JsonLint，错误是/在单词{ "lists": { "csv": "function(head, req) { var row, first = true; // output HTTP headers start({ headers: { 'Content-Type': 'text/csv' }, }); // iterate through the result set while (row = getRow()) { // get the doc (include_docs=true) var doc = row.doc; // if this is the first row if (first) { // output column headers send(Object.keys(doc).join(',') + 'n'); first = false; } // build up a line of output var line = ''; // iterate through each row for (var i in doc) { // comma separator if (line.length > 0) { line += ','; } // output the value, ensuring values that themselves // contain commas are enclosed in double quotes var val = doc[i]; if (typeof val == 'string' && val.indexOf(',') > -1) { line += '" ' + val.replace(/"/g, ' "" ') + ' "'; } else { line += val; } } line += 'n'; // send the line send(line); } } " } }前面开始。我无法在语法中看到错误，但必须在那里。如果有人能告诉我我的错误背后的原则，请。
