jQuery的$。员额函数的结果数据员额、函数、结果、数据

当我做一个AJAX调用(见下文code),什么是数据。我如何设置和获取数据的

  // $。员额()
 $(#邮报)。点击(函数(){
     $(#结果)HTML(ajax_load);
     $。员额(
         使用loadURL,
         {语:PHP,版本:5},
         功能(数据){
             $(#结果)HTML(数据);
         },
         JSON
     );
 });
 

解决方案

该数据是您输入的序列化值。例如:

 <形式GT;
    <输入类型=文本名称='myText1'值='你好'/>
    <输入类型=文本名称='myText2'值=世界/>
< /形式GT;

您现在可以运行这样的:

  VAR的myData = $('表')序列化()。
警报(myData的);
 

和你的消息框会说:

  myText1 =你好&放大器; myText2 =世界
 

的myData 的是要传递到.post的$函数的数据值。

既然你是新来的jQuery,我想也许建议您尝试使用 $就函数。有它有更多的选择,但我一直认为这是更简单,更容易理解比$。员额。下面是我使用它:

  $。阿贾克斯({
    类型:POST,//定义AJAX调用的类型(POST,GET等)
    网址:我-AJAX-的script.php,//要调用的脚本的名称
    数据:myData的,//你的数据要发送到脚本
    成功:函数(MSG){
        $(#结果)HTML(MSG); //你产生行动
    }
});
 

顺便说一句,不要忘了,为了使用jQuery的序列化功能,所有的投入需要有名称的属性设置,否则序列化功能会忽略它们。

When I make an ajax call (see code below), what is "data". How do I set and get data

//  $.post()  
 $("#post").click(function(){  
     $("#result").html(ajax_load);  
     $.post(  
         loadUrl,  
         {language: "php", version: 5},  
         function(data){  
             $("#result").html(data);  
         },  
         "json"  
     );  
 });

解决方案

The data is a serialized values of your inputs. Example:

<form>
    <input type='text' name='myText1' value='hello'/>
    <input type='text' name='myText2' value='world'/>
</form>

You could now run this:

var myData = $('form').serialize();
alert(myData);

And your messagebox would say:

myText1=hello&myText2=world

myData is the data value that you want to pass into the $.post function.

Since you are new to jQuery, I'd perhaps recommend you try using the $.ajax function instead. There are a lot more options for it, but I always thought it was more straightforward and easier to understand than $.post. Here is how I'd use it:

$.ajax({
    type: "POST",    //define the type of ajax call (POST, GET, etc)
    url: "my-ajax-script.php",   //The name of the script you are calling
    data: myData,    //Your data you are sending to the script
    success: function(msg){
        $("#result").html(msg);   //Your resulting action
    }
});

Btw, don't forget, in order to use the jQuery serialize function, all the inputs need to have the name attribute set, or else the serialize function will ignore them.
