Array對象重組

Question

我有Javascript對象是這樣的：

var value=[ RowDataPacket {options: 'card_img_url',options_value: 'https://ttest.com/logo.png' },RowDataPacket {options: 'card_img_url', options_value: 'https://ttest.com/logo2.png' },RowDataPacket {options: 'card_description', options_value: 'card 1 desc ' },RowDataPacket { options: 'card_description',options_value: 'card 2 desc' },RowDataPacket { 
options: 'card_footer',options_value: 'card 1 footer' },RowDataPacket { 
options: 'card_footer', options_value: 'card 2 footer' }]; 

var shaym = [];    
for(var i=0; i<value.length; i++){ 
var itemoptions = value[i].options; 
var itemoptionsval = value[i].options_value;    
var temp = {}; 
temp[itemoptions] = itemoptionsval; 
shaym.push(temp); 

}

console.log(shaym); 

它顯示 -

[{ card_img_url: 'https://ttest.com/logo.png' },{ card_img_url: 'https://ttest.com/logo2.png' },{ card_description: 'card 1 desc ' },{ card_description: 'card 2 desc' },{ card_footer: 'card 1 footer' },{ card_footer: 'card 2 footer' } ] 

形成上述代碼我想這種類型的對象： [ {card_img_url：'https://ttest.com/logo.png'，card_description：'card 1 desc'，card_footer：'card 1 footer'}，{c ard_img_url：'https://ttest.com/logo2.png'，card_description：'card 2 desc'，card_footer：'card 2 footer'}]

我該如何做到這一點？

您可以檢查對象的鍵是否與上一個對象的鍵相同。如果相同則採用結果數組的下一個索引，否則爲零。然後將該對象分配給結果集。

var data = [{ card_img_url: 'https://ttest.com/logo.png' }, { card_img_url: 'https://ttest.com/logo2.png' }, { card_description: 'card 1 desc ' }, { card_description: 'card 2 desc' }, { card_footer: 'card 1 footer' }, { card_footer: 'card 2 footer' }], 
 
    result = data.reduce(function (last, i) { 
 
     return function (r, a) { 
 
      var k = Object.keys(a)[0]; 
 
      i = k === last ? i + 1 : 0; 
 
      r[i] = r[i] || {}; 
 
      r[i][k] = a[k]; 
 
      last = k; 
 
      return r; 
 
     }; 
 
    }(), []); 
 

 
console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
