将表单字段与String变量进行比较

Question

String password = (String)session.getAttribute("password");
<input type = "password" placeholder = "Type your current password"  id = "pass"  />

现在，我想将表单字段中的值与变量＆＃34; password＆＃34;进行比较。如何使用JavaScript进行此操作？

Answer 1

这样做

html文件

<input type = "password" placeholder = "Type your current password"  id = "pass"  />

的script.js

var password="<%session.getAttribute("password");%>";
var pass=document.getElementById('pass').value; 
return pass.equals(password);
