How to convert password into md5 in jquery?
提问by Khushang Bhavnagarwala.
Actually i am creating changepassword page. and this is my function of checking old password is match with the existing password or not. And that password is stored in MD5 in database so i want to first convert that password in MD5 and after that i can check that password. Here is the code.
实际上我正在创建更改密码页面。这是我检查旧密码是否与现有密码匹配的功能。并且该密码存储在数据库中的 MD5 中，因此我想先在 MD5 中转换该密码，然后我可以检查该密码。这是代码。
function fnIsValidOldPassword()
{
var oldPassword = "";
var objUser = new Object();
objUser.UserID = <?php echo $_SESSION['UserId'] ?>;
$.ajax({
type: "POST",
url: "db.php?GetUser",
data: {data:objUser},
async:false,
dataType:"json",
success: function(response)
{
if(response.IsError)
alert(response.ErrorMessage);
else
oldPassword = response.Records[0].Password;
},
error:function(message)
{
alert("Error: " + message);
}
});
if($.md5($("#txtOldPassword").val())) != oldPassword)
^^ //here it shows error. that md5 is not a function.
{
$("#errorPassword")[0].innerHTML = "Wrong Old Password.";
$("#txtOldPassword").removeClass("successTextBox").addClass("errorTextBox");
return false;
}
$("#txtOldPassword").removeClass("errorTextBox").addClass("successTextBox");
$("#errorPassword")[0].innerHTML = "";
return true;
}
md5 is not a function in jquery then how to convert the password in md5.
md5 不是 jquery 中的函数，那么如何在 md5 中转换密码。

jQuery doesnt have a method to provide the md5 of a string. So you need to use some external script. There is a plugin called jQuery MD5. and it gives you number of methods to achieve md5. Few of those are
jQuery 没有提供字符串的 md5 的方法。所以你需要使用一些外部脚本。有一个名为 jQuery MD5 的插件。它为您提供了多种实现 md5 的方法。其中很少有人是
Create (hex-encoded) MD5 hash of a given string value:
创建给定字符串值的（十六进制编码）MD5 哈希：
var md5 = $.md5('value');
Create (hex-encoded) HMAC-MD5 hash of a given string value and key:
创建给定字符串值和键的（十六进制编码）HMAC-MD5 哈希：
var md5 = $.md5('value', 'key');
Create raw MD5 hash of a given string value:
创建给定字符串值的原始 MD5 哈希：
var md5 = $.md5('value', null, true);
Create raw HMAC-MD5 hash of a given string value and key:
创建给定字符串值和键的原始 HMAC-MD5 哈希：
var md5 = $.md5('value', 'key', true);
This might do what you want... Check the snippet here. jQuery MD5
这可能会做你想做的......检查这里的片段。jQuery MD5

and use like
并使用像
if(CryptoJS.MD5($("#txtOldPassword").val())) != oldPassword) {
}
//Following lines shows md5 value
//var hash = CryptoJS.MD5("Message");
//alert(hash);

Get the field value through the id and send with ajax
通过id获取字段值并用ajax发送
var field = $("#field").val();
$.ajax({
type: "POST",
url: "db.php",
data: {variable_name:field},
async:false,
dataType:"json",
success: function(response) {
alert(response);
}
});
At db.php file get the variable name
在 db.php 文件中获取变量名
$variable_name = $_GET['variable_name'];
mysql_query("SELECT password FROM table_name WHERE password='".md5($variable_name)."'");
