如何從數據庫中提取的json數據獲取特定值？

您好，我有問題顯示從數據庫中提取的JSON數據的特定值，我只想顯示產品名稱上的輸入文本如何做到這一點？我嘗試過，但它說沒有價值。如何從數據庫中提取的json數據獲取特定值？

這裏是我的JSON代碼： -

{"brcode":[{"id":"1","name":"Rolex Watch","description":"Rolex wrist watches","uom":"1000","brand":"1051","tax_id":"1","purchase_price":"5000","sale_price":"6000","barcode":"ROLEX5000","created_date":"2017-05-29 13:31:24","created_by":"1","updated_date":"2017-05-29 13:31:24","updated_by":"1","status":null},{"id":"3","name":"motorola X play","description":"Moto X play mobile phone","uom":"50","brand":"7845","tax_id":"1","purchase_price":"20000","sale_price":"25000","barcode":"MOTOXPLAY500","created_date":"2017-05-29 14:18:43","created_by":"0","updated_date":"2017-05-29 14:18:43","updated_by":"0","status":null},{"id":"4","name":" LG Smart LED TV","description":"Smart LED TV from LG","uom":"5","brand":"5420","tax_id":"1","purchase_price":"80000","sale_price":"100000","barcode":"LGSMART5012","created_date":"2017-05-29 15:39:35","created_by":"0","updated_date":"2017-05-29 15:39:35","updated_by":"0","status":null},{"id":"5","name":"Computer Intel","description":"Intel smart computer","uom":"1","brand":"1","tax_id":"1","purchase_price":"40000","sale_price":"50000","barcode":"INTELPC2123","created_date":"2017-05-29 17:59:31","created_by":"0","updated_date":"2017-05-29 17:59:31","updated_by":"0","status":null},{"id":"6","name":"DDR4 Ram","description":"Ram for computer","uom":"6","brand":"1","tax_id":"1","purchase_price":"4000","sale_price":"5000","barcode":"RAMDDR4","created_date":"2017-05-29 18:15:17","created_by":"0","updated_date":"2017-05-29 18:15:17","updated_by":"0","status":null}]}

這裏是我的功能： -

function get_barcodes() { 


    $.ajax({ 
     url: 'http://localhost/retail/main/ajax_barcodes/', 
     type: 'POST', 
     datatype: 'json', 
     data: { 'barcode': $('#brcode option:selected').val() }, 
     success: function (data) { 
      // var brcodes = JSON.parse(data); 
      //console.log(brcodes);   
      //var brCodes = JSON.parse(data); 
      //var json = JSON.parse(data); 
      //console.log(brCodes.brcode); 
      //$("#product_items_opts").val(barcodes.brcode.name); 
      // console.log(json); 

      console.log(data); 

     } 
    }); 

    // $('#prdct_barcode[' + product_barcode_counter + ']').each(function(){ 
    //  $('#prdct_barcode[' + product_barcode_counter + ']').change(function(){ 



    //  }); 
    // }); 


}

請忽略我寫只是爲了檢查值的評論部分。請告訴我如何從JSON數據顯示產品名稱？

是否想獲取所有產品名稱並將其顯示在某個地方？ – JSONGagnon

是的，我也想顯示選擇菜單的選項中的所有條形碼，我想追加所有的條形碼選項。 –

試試這個

var jsonData = JSON.parse(data); 
for(var i=0; i<jsonData.brcode.length; i++) { 
    var product = jsonData.brcode[i]; 
    console.log(product.name); 
}

Heyy非常感謝Nikita它的作品:) .. !! –

下面是一個基本的通過JSON循環來獲得產品的名稱和條形碼。這應該可以幫助你實現你想要做的事情。將這些代碼放在您的控制檯登錄數據的成功功能中。

var jsonData = JSON.parse(data); 
for(var i = 0; i < jsonData.brcode.length; i++){ 
    console.log(jsonData.brcode[i].name); 
    console.log(jsonData.brcode[i].barcode); 
}

這不會在控制檯中顯示任何內容 –

嘗試先使用JSON.parse解析數據。 – JSONGagnon
