getBody 仍然会抛出 "can't call getBody out of null" 错误，即使它在 Apps 脚本中不为 null

Question

getBody 在 Apps 脚本中仍然 returns null，尽管我已经四处寻找错误并进行了大部分调试。另一位用户（向我指出了大部分错误）说这段代码中的 getBody 不为空。这是我的代码还是 Apps 脚本的错误？

function myFunction() {

var searchResult = DocumentApp.getActiveDocument().getBody().findText("very",searchResult)
Logger.log(searchResult)



while (searchResult !== null) {

searchResult.getElement().asText().setAttributes(searchResult.getStartOffset(),searchResult.getEndOffsetInclusive(),"#FF000")

searchResult = DocumentApp.getActiveDocument().getBody().findText("very",searchResult)

}



function highlightProblem() {

var words = ["very","so","totally","really"] 

words.forEach(findText) 

  }


 function onOpen(){
DocumentApp.getUi().createMenu('everythingisnotfine.avi').addItem('Higlight Words That Make You Sound Like a Dandy', 'higlightProblem').addToUi()
}}

Answer 1

您的主要问题是您甚至在定义 searchResult 之前就在使用它。

var searchResult = DocumentApp.getActiveDocument().getBody().findText("very",searchResult)

因为您还没有定义 searchResult，所以您不能通过 findText() 和 searchResult 作为起点。一旦定义了第一个 searchResult 变量，就可以在 while 循环中使用它来查找匹配项

while (searchResult !== null) {
 searchResult = DocumentApp.getActiveDocument().getBody().findText(very,searchResult)
 }

其次，您在 myFunction() 的上下文中定义函数 onOpen() 和 highlightProblem()，就像这样

function myFunction(){  // <--- Start of my function

 function highlightProblem(){
 }
 function onOpen(){
 }
}                      //<-- End of my function

您需要单独定义每个函数，如下所示。

您的最终代码：

function findText(searchString) {
 Logger.log(searchString)
 var doc = DocumentApp.getActiveDocument()
 //var doc = DocumentApp.openByUrl("Copy and paste URL of your doc here")
 var searchResult = doc.getBody().findText(searchString)
 Logger.log(searchResult)
 var style = {};
  style[DocumentApp.Attribute.BACKGROUND_COLOR] = '#FFFF00';
 while (searchResult !== null) {
 searchResult.getElement().asText().setAttributes(searchResult.getStartOffset(),searchResult.getEndOffsetInclusive(),style)
 searchResult = DocumentApp.getActiveDocument().getBody().findText(searchString,searchResult)
 }
}

function highlightProblem() {
 var words = ["very","so","totally","really"] 
 words.forEach(findText)   
}



 function onOpen(){       
DocumentApp.getUi().createMenu('everythingisnotfine.avi').addItem('Higlight Words That Make You Sound Like a Dandy', 'highlightProblem').addToUi()
    }

运行代码的步骤
1) 按原样复制并粘贴到脚本编辑器中。然后运行函数 onOpen() 将自定义菜单添加到您的文档
2) 您可以从脚本编辑器或自定义菜单中运行高亮功能
3) 如果你仍然无法运行它取消注释（删除 //）这一行并复制并粘贴 URL 如前所述 //var doc = DocumentApp.openByUrl("Copy and paste URL of your doc here")

getBody 仍然会抛出 "can't call getBody out of null" 错误，即使它在 Apps 脚本中不为 null

getBody still chucks out a "can't call getBody out of null" error even though it isn't null in Apps Script
