1、xml格式的数据  数据模型

<?xml version="1.0" encoding="UTF-8" ?>

<root>

<item>

<strNowEngineer>dypro001</strNowEngineer>

<completeNum>3</completeNum>

<InTreatmentNum>0</InTreatmentNum>

</item>

<item>

<strNowEngineer>dypro002</strNowEngineer>

<completeNum>4</completeNum>

<InTreatmentNum>1</InTreatmentNum>

</item>

<item>

<strNowEngineer>dypro003</strNowEngineer>

<completeNum>5</completeNum>

<InTreatmentNum>2</InTreatmentNum>

</item>

<item>

<strNowEngineer>dypro004</strNowEngineer>

<completeNum>6</completeNum>

<InTreatmentNum>0</InTreatmentNum>

</item>

</root>

 

方法代码：

 

2、json格式数据  数据模型

{"item":[{"strNowEngineer":"dypro001","completeNum":"42","InTreatmentNum":"0"},

{"strNowEngineer":"dypro002","completeNum":"4","InTreatmentNum":"1"},

{"strNowEngineer":"dypro003","completeNum":"5","InTreatmentNum":"2"},

{"strNowEngineer":"dypro004","completeNum":"6","InTreatmentNum":"0"}]}

方法代码：

    
                     
     
        
      1        
      
    
     

 

3、json格式数据  数据模型

{

"root": {

"item": [

{

"strNowEngineer": "dypro001",

"completeNum": "3",

"InTreatmentNum": "0"

},

{

"strNowEngineer": "dypro002",

"completeNum": "4",

"InTreatmentNum": "1"

},

{

"strNowEngineer": "dypro003",

"completeNum": "5",

"InTreatmentNum": "2"

},

{

"strNowEngineer": "dypro004",

"completeNum": "6",

"InTreatmentNum": "0"

}

]

}

}

 

    
                     
     
        
      1        
      
    
     

和上一个差别：数据格式 多了一层节点，。代码中

var json=eval(data.root.item);

var strNowEngineer=json.root.item[i].strNowEngineer;做了修改

1.当url指向本地数据文件中，google浏览器不支持，火狐 ie支持。

2.eval()使用方法：当直接解析一个json数据格式的字符串时  使用var json=eval('('+result+')');

当解析由json数据格式具体字符串时使用  var json=eval(data.item);两者是不同的
