如果页面具有多个表单，则使用jquery / ajax进行表单提交而不刷新

只需自定义函数并添加参数

formid

processForm("id of the form");

function processForm(formId) {     //your validation pre    $.ajax( { type: 'POST', url: form_process.php, data: $("#"+formId).serialize(),  success: function(data) {     $('#message').html(data); }        } );    }<form action="" id="form1" method="post" onsubmit="processForm('form1');return false;"><input type='text' name='user_name' id='user_name' value='' /><input type='submit' name='submit' value='submit'/></form><form action="" id="form2" method="post" onsubmit="processForm('form2');return false;"><input type='text' name='user_name' id='user_name' value='' /><input type='submit' name='submit' value='submit'/></form><form action="" id="form3" method="post" onsubmit="processForm('form3');return false;"><input type='text' name='user_name' id='user_name' value='' /><input type='submit' name='submit' value='submit'/></form><div id='message'></div>
