AJAX提交POST

Question

没有数据

我似乎不具有当窗体通过jQuery的

我的问题的一个片段（代码减少到简化）提交发送的任何数据：

头：

 <script> 

function dSubmit(formName, formAction, fieldsToCheck, divToHide){ 


     // No Errors process form 


var url = formAction; // the script where you handle the form input. 

$.ajax({ 
     type: "POST", 
     url: url, 
     data: $("#" + formName).serialize(), // serializes the form's elements. 
     success: function(data) 
     {alert(data)} 
    }); 

return false; // avoid to execute the actual submit of the form. 


} 
</script> 

体：

<a onclick="dSubmit('treatmentDetails','treatments/processTreatments.php','','')"><img style="width:35px;" src="i/update-icon.png"/></a> 


<form name="treatmentdetails" id="treatmentdetails" 

action="processTreatments.php" method="POST"> 

    <input type="text" name="treatmentName" value="<?php echo $treatment;?>"/> 
<input type="text" name="treatmentId" value="<?php echo $treatmentId;?>"/><br> 

    </form> 

PHP（治疗/ processTreatments.php）：

$table = $dbPrefix."treatmentsOptions"; 

$treatmentId = $_POST['treatmentId']; 
$treatmentName = $_POST['treatmentName']; 
$query = mysql_query("UPDATE $table SET name='$treatmentName' WHERE id='$treatmentId'"); 

echo "variables = id: $treatmentId name: $treatmentName"; // according to jquery submit neither variable appear 

Answer 1

您排错treatmentDetails，修复为treatmentdetails。

$("#treatmentDetails").serialize()是返回空字符串。

您正确的代码是：

<a onclick="dSubmit('treatmentdetails','treatments/processTreatments.php','','')"><img style="width:35px;" src="i/update-icon.png"/></a>
