jquery，遍歷json數組

Question

我從webservice獲取以下JSON字符串。

[{"TITLE":"asdasdasd","DESCRIPTION":"asdasd","PORTFOLIOID":1}, 
{"TITLE":"sss","DESCRIPTION":"sss","PORTFOLIOID":2}, 
{"TITLE":"sdfsdf","DESCRIPTION":"sdfsfsdf","PORTFOLIOID":3}] 

我可以在jQuery中循環這個數組並輸出單個的鍵/值對嗎？

Answer 1

絕對。假設你告訴jQuery來評估該響應，JSON與AJAX方法，你只需做到這一點：

<script> 
$(data).each(function(idx, obj) //this loops the array 
{ 
    $(obj).each(function(key, value) //this loops the attributes of the object 
    { 
     console.log(key + ": " + value); 
    } 
} 
</script> 

Answer 2

var a = [{"TITLE":"asdasdasd","DESCRIPTION":"asdasd","PORTFOLIOID":1}, ....] 

$(a).each(function(index) 
{ 
    //this is the object in the array, index is the index of the object in the array 
    alert(this.TITLE + ' ' this.DESCRIPTION) 
});
