blocks|key|354556|text|为此，我倾向于使用JSON对象：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|354557|在服务器端，JSON对您的数据进行编码:在JavaScript端，我编写了一个函数，该函数将JSON对象作为参数并解压缩。|354558|在解压对象时，可以将数组的内容打印到<DIV>标记中，或者打印到页面上的任何位置(jQuery在这方面做得很好)。|offset|length|style|CODE|354559|entityMap^0|0|0|I|5|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@$F|O|G|P|H|I]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

I tend to use a JSON object for this: 

<ul>
<li>On the server side, JSON encode your data: <code>json_encode($data);</code></li>
<li>On the JavaScript side, I write a function that takes a JSON object as a parameter and unpack it.</li>
</ul>

When you unpack the object, you can print the array's contents into a <code>&lt;DIV&gt;</code> tag, or where ever you would like on the page (jQuery does a pretty sweet job of this).

blocks|key|3349950|text|为了回答你的问题(和我的回复，我在评论回复上没有空间了)，下面是我使用的代码的一个非常简化的子集：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3349951|jQuery中的Javascript+AJAX处理程序：|3349952|$.ajax({

To follow up to your question (and my reply, I ran out of space on the comment reply), here is a very simplified subset of the code I use:

Javascript AJAX handler in jQuery:

<pre><code>$.ajax({
 type: "POST",
 url: "BACKEND.php",
 timeout: 8000,
 data: "var1=" + myVar,
 dataType: "json",
 error: function(){
 $("#DIVID").html("&lt;div class='error'&gt;Error!&lt;/div&gt;");
 }, 
 success: function(jsonObj){
 $("#DIVID").html(jsonObj.mydata);
 }
 });


PHP Array:
$data['mydata'] = $myData;
</code></pre>

blocks|key|3137085|text|如果你在做内联数据，我一直喜欢这样做|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3137086|<script+type="text/javascript">
window.sitescriptdata+=+{};+
window.sitescriptdata.foo+=+(+<?php+echo+json_encode(+$structure+);+?>+);
</script>|code-block|syntax|javascript|3137087|对于基本的东西，省去了做AJAX回调的麻烦。此外，如果您想将数据粘合到DOM节点，那么“元对象”方式是我真正喜欢的方式。|3137088|<div+id="foobar">
+<div><object+class="metaobject">
++++++++<param+name="data"+value="<?php+echo+htmlentities(json_encode($data),+ENT_QUOTES+);?>"+/>
+</object></div>
</div>+|3137089|这看起来可能不是很好，但它是直接将数据与DOM节点关联的有效方法，而不需要知道到该节点的确切唯一路径。如果您有许多需要附加到特定屏幕元素的数据集，这将非常方便。|3137090|我通常使用jQuery的http://noteslog.com/metaobjects/插件，但它太简单了，我偶尔会自己写(有一段时间我找不到这个插件，但它的工作原理很新)|offset|length|3137091|完成后，将会有|3137092|$("div#foobar+>div“).get().data。($yourarrayhere)|3137093|对你的代码是可见的。|3137094|entityMap|0|LINK|mutability|MUTABLE|url|http://noteslog.com/metaobjects/^0|0|0|0|0|0|C|W|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|14|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|15|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|16|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|17|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|18|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|19|8|@]|9|@$O|1A|P|1B|1|1C]]|A|$]]|$1|Q|3|R|5|6|7|1D|8|@]|9|@]|A|$]]|$1|S|3|T|5|6|7|1E|8|@]|9|@]|A|$]]|$1|U|3|V|5|6|7|1F|8|@]|9|@]|A|$]]|$1|W|3|-4|5|6|7|1G|8|@]|9|@]|A|$]]]|X|$Y|$5|Z|10|11|A|$12|13]]]]

If you're doing inline data, I've always been fond of doing 

<pre><code>&lt;script type="text/javascript"&gt;
window.sitescriptdata = {}; 
window.sitescriptdata.foo = ( &lt;?php echo json_encode( $structure ); ?&gt; );
&lt;/script&gt;
</code></pre>

For basic stuff, saves you doing an AJAX callback. Also, if you want to glue data to a DOM node, the "metaobject" way is something I really love. 

<pre><code>&lt;div id="foobar"&gt;
 &lt;div&gt;&lt;object class="metaobject"&gt;
 &lt;param name="data" value="&lt;?php echo htmlentities(json_encode($data), ENT_QUOTES );?&gt;" /&gt;
 &lt;/object&gt;&lt;/div&gt;
&lt;/div&gt; 
</code></pre>

Now this may not look great, but its an effective way of associating data directly with a DOM node without needing to know the exact unique path to that node. Very handy if you have many many datasets that need to be attached to specific screen elements. 

I usually use <a href="http://noteslog.com/metaobjects/" rel="noreferrer">http://noteslog.com/metaobjects/</a> plugin for jQuery, but its so simple I have on occasion written it myself ( there was a time I couldn't find the plugin, but new how it worked )

When done, there will be 

$("div#foobar > div").get().data.($yourarrayhere) 

Visible to your code.

blocks|key|357273|text|我也是个新手，也许这种方法不是最安全的，但是你可以把你的javascript数组转换成字符串，然后通过URL传递给php去获取。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|357274|所以：|357275|for(var+i=0;i+<+jsarray.length;i%2B%2B)+
{
var+x+=+jsarray[i];
urlstring+%2B=+"myvalue[]="%2Bx%2B"&";
}

document.location.href+=+"mypage.php?"%2Burlstring;|code-block|syntax|javascript|357276|然后php将是：|357277|$phparray+=+$_GET['myvalue'];|357278|希望这能有所帮助|357279|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|U|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

im still fairly new too say maybe this method isnt the most secure, but you can always turn your javascript array into a string and then pass it through the URL for the php to GET.

so:

<pre><code>for(var i=0;i &lt; jsarray.length;i++) 
{
var x = jsarray[i];
urlstring += "myvalue[]="+x+"&amp;";
}

document.location.href = "mypage.php?"+urlstring;
</code></pre>

and then the php would be:

<pre><code>$phparray = $_GET['myvalue'];
</code></pre>

hope that helps

blocks|key|3137143|text|在像here这样的AJAX示例中，您可以通过以下方式解决此问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3137144|.php文件(ajax返回函数)|3137145|$myArray+=+array("object_id"=>1,+"object_title"=>"Testobject");
return+json_encode($myArray);|code-block|syntax|javascript|3137146|.js文件(javascript函数)|3137147|...
if(g_httpRequest.readyState+==+4)
{
var+jsonRes+=+JSON.parse(g_httpRequest.responseText);
alert(jsonRes.object_title)
}
...|3137148|entityMap|0|LINK|mutability|MUTABLE|url|http://netisoft.net/basic_tutorial_ajax.html^0|2|4|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@$A|X|B|Y|1|Z]]|C|$]]|$1|D|3|E|5|6|7|10|8|@]|9|@]|C|$]]|$1|F|3|G|5|H|7|11|8|@]|9|@]|C|$I|J]]|$1|K|3|L|5|6|7|12|8|@]|9|@]|C|$]]|$1|M|3|N|5|H|7|13|8|@]|9|@]|C|$I|J]]|$1|O|3|-4|5|6|7|14|8|@]|9|@]|C|$]]]|P|$Q|$5|R|S|T|C|$U|V]]]]

In an AJAX example like <a href="http://netisoft.net/basic_tutorial_ajax.html" rel="nofollow">here</a> you can solve this problem on this way:

.php file (ajax return function)

<pre><code>$myArray = array("object_id"=&gt;1, "object_title"=&gt;"Testobject");
return json_encode($myArray);
</code></pre>

.js file (javascript function)

<pre><code>...
if(g_httpRequest.readyState == 4)
{
var jsonRes = JSON.parse(g_httpRequest.responseText);
alert(jsonRes.object_title)
}
...
</code></pre>

So I have an array of records retreived from a database. The array is in the format;

<pre><code>$rows[0]['id']=1;
$rows[0]['title']='Abc';
$rows[0]['time_left']=200;


$rows[1]['id']=2;
$rows[1]['title']='XYZ';
$rows[1]['time_left']=300;
//And so on upto 10-20 rows
</code></pre>

What's the best way of transferring this array over to my javascript code? I'd like the javascript to be able to loop through all of the records, and using the 'id' attribute, update the div with that id with some information. 

My javascript code is in an external .js file, but i'm able to execute php code in the HTML code of my page. So I could do something like this:

In my_file.js:

<pre><code>var rows=New Array();
</code></pre>

In HTML code:

<pre><code>&lt;html&gt;
&lt;head&gt;
&lt;script type="text/javascript" src="js/my_file.js"&gt;&lt;/script&gt;

&lt;script type="text/javascript"&gt;
&lt;? foreach ($rows as $row):?&gt;
&lt;? extract($row);?&gt;
rows[&lt;?=$id;?&gt;]['title']="&lt;?=$title;?&gt;";
//And so on
&lt;? endforeach;?&gt;
&lt;/script&gt;
</code></pre>
