Select JSON 未格式化代碼和漂亮打印格式化 JSON 到 DIV

Question

我有一個 function 接受選擇文本，該文本是未格式化的 JSON 代碼，我試圖使用字符串化方法將 JSON 代碼格式化為（pretty 視圖）。 這是代碼：

 function prettyPrintJSON(selectionInfo) {
  const unformattedJSON = selectionInfo.selectionText
  const formattedJSON = JSON.stringify(unformattedJSON, null, '\t')
}

這是未格式化的 JSON 代碼：

{"colors":[{"color":"black","category":"hue","type":"primary","code":{"rgba":[255,255,255,1],"hex":"#000"}},{"color":"white","category":"value","code":{"rgba":[0,0,0,1],"hex":"#FFF"}},{"color":"red","category":"hue","type":"primary","code":{"rgba":[255,0,0,1],"hex":"#FF0"}},{"color":"blue","category":"hue","type":"primary","code":{"rgba":[0,0,255,1],"hex":"#00F"}},{"color":"yellow","category":"hue","type":"primary","code":{"rgba":[255,255,0,1],"hex":"#FF0"}},{"color":"green","category":"hue","type":"secondary","code":{"rgba":[0,255,0,1],"hex":"#0F0"}}]} 

這就是它在表格中的樣子：

如您所見，它沒有格式化。 此外，我在谷歌瀏覽器擴展上使用它並使用 vue.js 作為框架來構建一個表到 output 同一個表中不同類型的數據。 有什么我想念的想法嗎？ 謝謝

把那個\t變成一個數字來表示你想要多少個縮進空格

 let json = {"colors":[{"color":"black","category":"hue","type":"primary","code":{"rgba":[255,255,255,1],"hex":"#000"}},{"color":"white","category":"value","code":{"rgba":[0,0,0,1],"hex":"#FFF"}},{"color":"red","category":"hue","type":"primary","code":{"rgba":[255,0,0,1],"hex":"#FF0"}},{"color":"blue","category":"hue","type":"primary","code":{"rgba":[0,0,255,1],"hex":"#00F"}},{"color":"yellow","category":"hue","type":"primary","code":{"rgba":[255,255,0,1],"hex":"#FF0"}},{"color":"green","category":"hue","type":"secondary","code":{"rgba":[0,255,0,1],"hex":"#0F0"}}]}; console.log(JSON.stringify(json, null, 2)); // spacing level = 2);
