代碼如下

　　　　　　　　　　exportRaw(‘text.txt‘,‘123123123‘)

                function fakeClick(obj) {
                  var ev = document.createEvent("MouseEvents");
                  ev.initMouseEvent("click", true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
                  obj.dispatchEvent(ev);
                }

                
 
function exportRaw(name, data) {
                  var urlObject = window.URL || window.webkitURL || window;
                  var export_blob = new Blob([data]);
                  var save_link = document.createElementNS("http://www.w3.org/1999/xhtml", "a")
                  save_link.href = urlObject.createObjectURL(export_blob);
                  save_link.download 
 
= name;
                  fakeClick(save_link);
                } 

js 把字符串保存為txt文件，並下載到本地
