谷歌应用程序脚本中的Google Picker方法“setSelectableMimeTypes不是函数”错误

Question

我正尝试在Google应用程序脚本中使用google picker API，以允许用户选择要上载文档的文件夹。我使用下面的代码

HTML文件

function change_destination() 
{ 
gapi.load('picker', {'callback': function(){pickerApiLoaded = true;}}); 
google.script.run.withSuccessHandler(createPicker).getOAuthToken(); 
} 
function createPicker(token) 
{ 
    var docsView = new google.picker.DocsView().setSelectFolderEnabled(true).setParent('root'); 
    var callback = function(data) 
    { 
    if (data.action == google.picker.Action.PICKED) 
    { 
    var doc = data.docs[0]; 
    console.log("You picked " + doc.id); 
    } 
    }; 
    var picker = new google.picker.PickerBuilder().setSize("650","470").setOAuthToken(token).addView(docsView).setOrigin('https://docs.google.com').setCallback(callback).build(); 
    picker.setSelectableMimeTypes('application/vnd.google-apps.folder'); 
    picker.setVisible(true); 
} 


<script type="text/javascript" src="https://apis.google.com/js/api.js"></script> 

CODE.gs

function getOAuthToken() 
{ 
    return ScriptApp.getOAuthToken(); 
} 

正在以下错误 “setSelectableMimeTypes是不是一个函数”

Answer 1

你在构建选择器之前需要设置setSelectableMimeTypes。

var picker = new google.picker.PickerBuilder() 
     .setSize("650","470") 
     .setSelectableMimeTypes('application/vnd.google-apps.folder') //not sure about this Mime type 
     .setOAuthToken(token) 
     .addView(docsView) 
     .setOrigin(google.script.host.origin) 
     .setCallback(callback) 
     .build() 
    picker.setVisible(true); 

仅显示选取器视图中的文件夹。

var docsView = new google.picker.DocsView(google.picker.ViewId.FOLDERS).setParent('root'); 
    var picker = new google.picker.PickerBuilder() 
     .setSize("650","470") 
     .setOAuthToken(token) 
     .addView(docsView) 
     .setOrigin(google.script.host.origin) 
     .setCallback(callback) 
     .build() 
    picker.setVisible(true);
