had same problem today, Your topic helped me so here goes solution ;)

<pre><code> alert(result.d[0].EmployeeTitle);

Be careful, <code>d</code> is the list.

<pre><code>for (var i = 0; i &lt; result.d.length; i++) { 
 alert(result.d[i].employeename);
}
</code></pre>

blocks|key|1572179|text|很接近了！试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1572180|for+(var+prop+in+result)+{

}|code-block|syntax|javascript|1572181|更新：|1572182|如果您的结果确实是一个对象的数组，那么您可能必须这样做：|1572183|for+(var+prop+in+result[0])+{

++++}
}|1572184|或者，如果您想遍历数组中的每个结果(如果还有更多结果)，请尝试：|1572185|for+(var+i+=+0;+i+<+results.length;+i%2B%2B)+{

It's close! Try this:

<pre><code>for (var prop in result) {
 if (result.hasOwnProperty(prop)) {
 alert(result[prop]);
 }
}
</code></pre>

Update:

If your result is truly is an array of one object, then you might have to do this:

<pre><code>for (var prop in result[0]) {
 if (result[0].hasOwnProperty(prop)) {
 alert(result[0][prop]);
 }
}
</code></pre>

Or if you want to loop through each result in the array if there are more, try:

<pre><code>for (var i = 0; i &lt; results.length; i++) {
 for (var prop in result[i]) {
 if (result[i].hasOwnProperty(prop)) {
 alert(result[i][prop]);
 }
 }
}
</code></pre>

This will work! 

<pre><code>$(document).ready(function ()
 {
 $.ajax(
 {
 type: 'POST',
 url: "/Home/MethodName",
 success: function (data) {
 //data is the string that the method returns in a json format, but in string
 var jsonData = JSON.parse(data); //This converts the string to json

 for (var i = 0; i &lt; jsonData.length; i++) //The json object has lenght
 {
 var object = jsonData[i]; //You are in the current object
 $('#olListId').append('&lt;li class="someclass&gt;' + object.Atributte + '&lt;/li&gt;'); //now you access the property.

 }

 /* JSON EXAMPLE
 [{ "Atributte": "value" }, 
 { "Atributte": "value" }, 
 { "Atributte": "value" }]
 */
 }
 });
 });
</code></pre>

The main thing about this is using the property exactly the same as the attribute of the JSON key-value pair.

blocks|key|1357147|text|我有一个电话：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1357148|$('#select_box_id').change(function()+{

I have the following call:

<pre><code>$('#select_box_id').change(function() {
 var action = $('#my_form').attr('action');
 $.get(action,{},function(response){
 $.each(response.result,function(i) {

 alert("key is: " + i + ", val is: " + response.result[i]);

 });

The structure coming back from the server look like:

<pre><code>{"result":{"1":"waterskiing","2":"canoeing","18":"windsurfing"}}
</code></pre>

I am returning a List&lt;> from a webservice as a List of JSON objects. I am trying to use a for loop to iterate through the list and grab the values out of the properties. This is a sample of the returning JSON:

<pre><code>{"d":[{"__type":"FluentWeb.DTO.EmployeeOrder",
 "EmployeeName":"Janet Leverling",
 "EmployeeTitle":"Sales Representative",
 "RequiredDate":"\/Date(839224800000)\/",
 "OrderedProducts":null}]}
</code></pre>

So I am trying to extract the contents using something like this:

<pre><code>function PrintResults(result) {

for (var i = 0; i &lt; result.length; i++) { 
 alert(result.employeename);
}
</code></pre>

How should this be done?

Loop through JSON object List

服务器

JSON

我从JSON服务返回一个List<>作为JSON对象的列表。我尝试使用for循环来遍历列表，并从属性中获取值。这是一个返回JSON的示例：{"d":[{"__type":"FluentWeb.DTO.EmployeeOrder", "EmployeeName":"Janet Leverling", "EmployeeTitle":"Sales Representative", "RequiredD
