使用jquery的多級JSON數據

Question

任何人都可以告訴我如何訪問來自下面的json的「item2」的數據？

JSON

item1: [ 
    { "location": [ 
     {"latitude": value, "longitude": value, "fileName": value } 
    ], 
    "links": [ 
     {"latitude": value, "longitude": value, "fileName": value }, 
     {"latitude": value, "longitude": value, "fileName": value }, 
     {"latitude": value, "longitude": value, "fileName": value } 
    ] 
    } 
], 
item2: [ //repeat of above ] 

Answer 1

這將幫助您從JSON迭代item2

<script language="javascript" > 

document.writeln("<h2>JSON array object</h2>"); 

var books = { "Java" : [ 
     { "Name" : "Java is Simple", "price" : 500 }, 
     { "Name" : "The Complete Reference", "price" : 600 } 
    ],      
    "Spring" : [ 
     { "Name" : "Spring is mvc", "price" : 300 }, 
     { "Name" : "Basics Spring", "price" : 200 } 
    ]  
}  

var i = 0 
document.writeln("<table border='2'><tr>"); 
for(i=0;i<books.Java.length;i++) 
{ 
    document.writeln("<td>"); 
    document.writeln("<table border='1' width=100 >"); 
    document.writeln("<tr><td><b>Name</b></td><td width=50>" 
    + books.Java[i].Name+"</td></tr>"); 
    document.writeln("<tr><td><b>Price</b></td><td width=50>" 
    + books.Java[i].price +"</td></tr>"); 
    document.writeln("</table>"); 
    document.writeln("</td>"); 
} 

for(i=0;i<books.Spring.length;i++) 
{ 
    document.writeln("<td>"); 
    document.writeln("<table border='1' width=100 >"); 
    document.writeln("<tr><td><b>Name</b></td><td width=50>" 
    + books.Spring[i].Name+"</td></tr>"); 
    document.writeln("<tr><td><b>Price</b></td><td width=50>" 
    + books.Spring[i].price+"</td></tr>"); 
    document.writeln("</table>"); 
    document.writeln("</td>"); 
} 
document.writeln("</tr></table>"); 
</script>
