layui.use模块外部使用其内部定义的js封装函数方法

// 调用成功

 <div class="layui-form-item " >
    <label class="layui-form-label">原密码</label>
    <div class="layui-input-block">
     <input type="text" name="password" id="oldpass" οnchange="pass1()" class="layui-input">
    </div>
  </div>

//无法调用

 <div class="layui-form-item " >
    <label class="layui-form-label">新密码</label>
    <div class="layui-input-block">
     <input type="text" name="password" id="oldpass" οnchange="pass2()" class="layui-input">
    </div>
  </div>

<script >
   layui.use('form', function(){
    var form=layui.form;


    window.pass1=function ()
    {
     var x=document.getElementById("oldpass");
     x.value=x.value.toUpperCase();
