登录代码在Internet Explorer中无效，但在Chrome和Firefox中无效(Sign-in code not working in Internet Explorer but yes in Chrome and Firefox)

我希望这不是一个冗长乏味的问题...我正在研究别人写的代码。 问题只是它在Chrome和Firefox上运行良好，但在Internet Explorer上运行不正常。 当点击提交页面时，只需重新加载并重新开始即可。 我不知道为什么？ 有人可以帮忙吗？

这是HTML：它本质上是两个要求电话号码和密码的字段......

<form name="form1" id="form1" onSubmit="get_client_data(); return false;" method="post" > <input type="hidden" name="random_1" id="random_1" value="<?=$session['random_1']?>" /> <h2>ENTER THE NUMBER YOU’D LIKE TO REFILL</h2> <input placeholder="ENTER YOUR PHONE NUMBER:" name="phone_number" id="phone_number" type="text" class="form_input" onBlur="convert_phone(this.value,'phone_number');" /> <h2>ENTER YOUR PIN</h2> <input placeholder="ENTER YOUR PIN CODE:" name="pin_id" id="pin_id" type="text" class="form_input" onBlur="check_validity(this.value, 'pin_id');" /><br> <input name="" type="submit" value="GO" class="right button go" id="step_1" /> </form>

onSubmit发送到以下javascript函数:(这使用ajax来确定数字和引脚是否匹配，如果它们匹配 - 它将启用HTML的其他部分（此处未给出））

function get_client_data(){ var pin_id = $('#pin_id').val(); var phone_number = $('#phone_number').val(); var random_1 = $('#random_1').val(); $.ajax({ type: "POST", url: "front_end_functions.php", data: "phone_number="+phone_number+"&plan="+plan+"&pin_id="+pin_id+"&random_1="+random_1+"&function=get_client_data", dataType: 'json', success: function(msg){ if(msg == 'error') { alert('error'); return false; } else if(msg == 'error2') { alert('error'); return false; } else { $('#div_1').addClass('deselect'); $('#div_2').removeClass('deselect'); $('#phone_number').attr('disabled','disabled'); $('#pin_id').attr('disabled','disabled'); $('#step_1').attr('disabled','disabled'); $('#phone').removeAttr('disabled'); $('#carrier').removeAttr('disabled'); $('#plan').removeAttr('disabled'); $('#step_2').removeAttr('disabled'); $('#phone').val(msg[1]); $('#carrier').val(msg[2]); $('#plan').val(msg[3]); } } }); }

Ajax发送的函数看起来像这样（你可以看到我正在使用PDO - 这会导致问题吗？）：

if($_REQUEST['function'] == 'get_client_data') { $random_1 = $_REQUEST['random_1']; $ip = getenv('HTTP_CLIENT_IP')?: getenv('HTTP_X_FORWARDED_FOR')?: getenv('HTTP_X_FORWARDED')?: getenv('HTTP_FORWARDED_FOR')?: getenv('HTTP_FORWARDED')?: getenv('REMOTE_ADDR'); $query = $db->prepare("SELECT * FROM sessions WHERE id = ?"); $query->execute(array($ip)); $session = $query->fetch(); if($session['random_1'] == $random_1) { $phone_number = $_REQUEST['phone_number']; $pin_id = $_REQUEST['pin_id']; $sql = "SELECT c.cid, cp.phone, cr.carrier_name, p.plan_name ,cp.carrier as cr_id,cp.plan as p_id FROM clients c, client_phones cp , carriers cr, plans p WHERE cp.phone = ? AND cp.client_id = ? AND cp.deleted = 0 AND c.cid = cp.client_id AND c.status = 'a' AND cr.carrier_id = cp.carrier AND p.plan_id = cp.plan"; $query = $db->prepare($sql); $query->execute(array($phone_number, $pin_id)); $result = $query->fetch(); if(!empty($result)){ $_SESSION['client'] = $result; echo json_encode($result); }else{ echo json_encode('error'); } }else{ echo json_encode('error2'); } }

谢谢！

I hope this isn't too much of a tedious question... I am working on this code that someone else wrote. The problem simply is that it works fine on Chrome and Firefox but not on Internet Explorer. What happens is when clicking on the submit the page simply reloads and starts afresh. I have no clue why? Can anyone help?

Here is the HTML: It is essentially two fields that ask for phone number and pin code...

<form name="form1" id="form1" onSubmit="get_client_data(); return false;" method="post" > <input type="hidden" name="random_1" id="random_1" value="<?=$session['random_1']?>" /> <h2>ENTER THE NUMBER YOU’D LIKE TO REFILL</h2> <input placeholder="ENTER YOUR PHONE NUMBER:" name="phone_number" id="phone_number" type="text" class="form_input" onBlur="convert_phone(this.value,'phone_number');" /> <h2>ENTER YOUR PIN</h2> <input placeholder="ENTER YOUR PIN CODE:" name="pin_id" id="pin_id" type="text" class="form_input" onBlur="check_validity(this.value, 'pin_id');" /><br> <input name="" type="submit" value="GO" class="right button go" id="step_1" /> </form>

The onSubmit sends to the following javascript function: (this uses ajax to determine if the number and pin match and if they do - it will enable other parts of the HTML (not given here))

function get_client_data(){ var pin_id = $('#pin_id').val(); var phone_number = $('#phone_number').val(); var random_1 = $('#random_1').val(); $.ajax({ type: "POST", url: "front_end_functions.php", data: "phone_number="+phone_number+"&plan="+plan+"&pin_id="+pin_id+"&random_1="+random_1+"&function=get_client_data", dataType: 'json', success: function(msg){ if(msg == 'error') { alert('error'); return false; } else if(msg == 'error2') { alert('error'); return false; } else { $('#div_1').addClass('deselect'); $('#div_2').removeClass('deselect'); $('#phone_number').attr('disabled','disabled'); $('#pin_id').attr('disabled','disabled'); $('#step_1').attr('disabled','disabled'); $('#phone').removeAttr('disabled'); $('#carrier').removeAttr('disabled'); $('#plan').removeAttr('disabled'); $('#step_2').removeAttr('disabled'); $('#phone').val(msg[1]); $('#carrier').val(msg[2]); $('#plan').val(msg[3]); } } }); }

The function that Ajax sends to looks like this (as you can see I am using PDO - does that cause problems?):

if($_REQUEST['function'] == 'get_client_data') { $random_1 = $_REQUEST['random_1']; $ip = getenv('HTTP_CLIENT_IP')?: getenv('HTTP_X_FORWARDED_FOR')?: getenv('HTTP_X_FORWARDED')?: getenv('HTTP_FORWARDED_FOR')?: getenv('HTTP_FORWARDED')?: getenv('REMOTE_ADDR'); $query = $db->prepare("SELECT * FROM sessions WHERE id = ?"); $query->execute(array($ip)); $session = $query->fetch(); if($session['random_1'] == $random_1) { $phone_number = $_REQUEST['phone_number']; $pin_id = $_REQUEST['pin_id']; $sql = "SELECT c.cid, cp.phone, cr.carrier_name, p.plan_name ,cp.carrier as cr_id,cp.plan as p_id FROM clients c, client_phones cp , carriers cr, plans p WHERE cp.phone = ? AND cp.client_id = ? AND cp.deleted = 0 AND c.cid = cp.client_id AND c.status = 'a' AND cr.carrier_id = cp.carrier AND p.plan_id = cp.plan"; $query = $db->prepare($sql); $query->execute(array($phone_number, $pin_id)); $result = $query->fetch(); if(!empty($result)){ $_SESSION['client'] = $result; echo json_encode($result); }else{ echo json_encode('error'); } }else{ echo json_encode('error2'); } }

Thanks!

最满意答案

是的 - 完成了它，在IE上使用调试器（抱歉没有这么做），它说ajax代码的数据部分中的'plan'是未定义的。 这就造成了错误。 有趣的是Chrome和Firefox没有这个问题......

Yep - worked it out, Using the debugger on IE (sorry for not doing that earlier) it says that 'plan' in the data part of the ajax code is undefined. So that caused the error. Interesting that Chrome and Firefox don't have that problem...
