从Google云端硬盘电子表格单元获取数据

Question

I am attempting to display some data in a HTML document coming from a Google Drive Spreadsheet cell by using the following javascript code:

var URL = "https://docs.google.com/spreadsheet/pub?key=0AhQNAOBkQ63ldFl6N0tDeTFDYWVXeF8yQ0kwdWtoZnc&gid=0&single=true&gid=0&output=txt&range=";
$.ajax(URL + "D2").done(function(result){ document.getElementById("demo").innerHTML=result; });

This works fine when I have an HTML tag with a "demo" id, but I need the value as a variable so I can display it anywhere in the page and not in a specific HTML element.

You'll need to specify async:false because otherwise the variable probably won't end up getting set until after you've tried to use it. Also, for some scope reasons it's easiest to reference a variable in the context of the window (ie window.variable ).

var URL = "https://docs.google.com/spreadsheet/pub?key=0AhQNAOBkQ63ldFl6N0tDeTFDYWVXeF8yQ0kwdWtoZnc&gid=0&single=true&gid=0&output=txt&range=";

window.variable = "test";

$.ajax({url:URL + "D2",async:false}).done(function(result){ window.variable = result; });

document.getElementById("demo").innerHTML = window.variable;
