查找文本(多次)和突出显示

Question

我想在Google文档中找到一个单词的所有实例并突出显示它们(或评论 - 任何事情都如此突出).我创建了以下函数,但它只找到了单词的第一个外观(在本例中为"the").任何关于如何找到该单词的所有实例的想法将不胜感激!

function findWordsAndHighlight() {
var doc = DocumentApp.openById(Id);
var text = doc.editAsText();
//find word "the"
var result = text.findText("the");
//change background color to yellow
result.getElement().asText().setBackgroundColor(result.getStartOffset(),                result.getEndOffsetInclusive(), "#FFFF00");
};

Answer 1

我知道这是一个老人,但这是我在Google Script中为文本添加效果的方法.下面的示例专门用于为文档中特定字符串的所有匹配项添加突出显示.

function highlightText(findMe) {
    var body = DocumentApp.getActiveDocument().getBody();
    var foundElement = body.findText(findMe);

    while (foundElement != null) {
        // Get the text object from the element
        var foundText = foundElement.getElement().asText();

        // Where in the Element is the found text?
        var start = foundElement.getStartOffset();
        var end = foundElement.getEndOffsetInclusive();

        // Change the background color to yellow
        foundText.setBackgroundColor(start, end, "#FCFC00");

        // Find the next match
        foundElement = body.findText(findMe, foundElement);
    }
}

Answer 2

嗯，简单的 javascript 就足够了，

var search = searchtext;
var index = -1;

while(true)
 {
   index = text.indexOf(search,index+1);

   if(index == -1)
     break;
   else
     /** do the required operation **/
 }

希望这可以帮助！
