如何修复没有’Access-Control-Allow-Origin’标题出现’错误
我正在编写一个程序，当我尝试提交数据时，我得到了这个错误，“请求资源上没有’Access-Control-Allow-Origin’标题。因此不允许原点’null’访问。” 这是我在js中的代码：
var $form = $('form#Send'), url = 'https://script.google.com/macros/s/AKfycbxX8ZIziIntqczwArCxE536FAW3urjRYr477sg7ddZ5voMLYw/exec' $('#submitit').on('click', function(e) { e.preventDefault(); var jqxhr = $.ajax({ url: url, method: "GET", dataType: "json", data: $form.serializeObject() }); 这是我的Google脚本代码：
// original from: http://mashe.hawksey.info/2014/07/google-sheets-as-a-database-insert-with-apps-script-using-postget-methods-with-ajax-example/ // original gist: https://gist.github.com/willpatera/ee41ae374d3c9839c2d6 function doGet(e){ return handleResponse(e); } // Enter sheet name where data is to be written below var SHEET_NAME = "GAME_THING"; var SCRIPT_PROP = PropertiesService.getScriptProperties(); // new property service function handleResponse(e) { // shortly after my original solution Google announced the LockService[1] // this prevents concurrent access overwritting data // [1] http://googleappsdeveloper.blogspot.co.uk/2011/10/concurrency-and-google-apps-script.html // we want a public lock, one that locks for all invocations var lock = LockService.getPublicLock(); lock.waitLock(30000); // wait 30 seconds before conceding defeat. try { // next set where we write the data - you could write to multiple/alternate destinations var doc = SpreadsheetApp.openById(SCRIPT_PROP.getProperty("key")); var sheet = doc.getSheetByName(SHEET_NAME); // we'll assume header is in row 1 but you can override with header_row in GET/POST data var headRow = e.parameter.header_row || 1; var headers = sheet.getRange(1, 1, 1, sheet.getLastColumn()).getValues()[0]; var nextRow = sheet.getLastRow()+1; // get next row var row = []; // loop through the header columns for (i in headers){ if (headers[i] == "Timestamp"){ // special case if you include a 'Timestamp' column row.push(new Date()); } else { // else use header name to get data row.push(e.parameter[headers[i]]); } } // more efficient to set values as [][] array than individually sheet.getRange(nextRow, 1, 1, row.length).setValues([row]); // return json success results return ContentService .createTextOutput(JSON.stringify({"result":"success", "row": nextRow})) .setMimeType(ContentService.MimeType.JSON); } catch(e){ // if error return this return ContentService .createTextOutput(JSON.stringify({"result":"error", "error": e})) .setMimeType(ContentService.MimeType.JSON); } finally { //release lock lock.releaseLock(); } } function setup() { var doc = SpreadsheetApp.getActiveSpreadsheet(); SCRIPT_PROP.setProperty("key", doc.getId()); }
这段代码应该从html表单发送数据到google工作表文档，我按照文章的教程 。
试试这个。 或尝试在其他浏览器中运行它
