对字段和FileUpload进行表单验证

Question

我希望在包含文本输入和fileupload文件附件的表单上执行验证/必填字段。

脚本接受输入并允许用户附加文件。提交后，它会将输入字段添加到电子表格并将文件上传到我的驱动器。我想要做的是强制文本输入和下拉列表来回答并需要文件附件。

我找到了示例"Example validation"的链接，但是我在尝试将其添加到代码中的click处理程序时遇到了问题。任何人都可以帮助指出正确的方向吗？

// Script-as-app template.
var submissionSSKey = 'Insert SS Key';

编辑 - 在第二个文件上传和添加中添加将无法启用

我已经回去编辑脚本并修改了一下基本上执行与以前相同的功能，但是这个需要上传两个文件。我遵循相同的代码，但在测试后，提交按钮将永远不会启用..这是更新的代码：

编辑 - 添加CliHandler4 我更新了代码以反映第4个cliHandler，但我仍然无法激活提交按钮。不知道为什么它失败了......我已经好几次看过了，我似乎无法弄清楚出了什么问题。这是代码

编辑作为答案：用户界面中缺少一个小部件（mortgageIns）

Answer 1

一种简单的方法是使用另一个带验证器的客户端处理程序。我建议将它放在fileUpload上，如下所示:(在同一个地方的代码中替换）

  var cliHandler2 = app.createClientHandler().validateLength(loanAmountTextbox, 1, 20)
  .validateLength(borrowerTextbox, 1, 20).validateLength(lienPos, 1, 20).forTargets(submitButton).setEnabled(true);// you can add more conditions here (widget name, minimum length, max length)

  var upLoad = app.createFileUpload().setName('thefile').addChangeHandler(cliHandler2);

，这个启用提交按钮！你可以test it here

---

修改

这是检查客户端处理程序上所有小部件的更复杂的选项....我重现整个相关部分并更新在线示例 - EDIT3 ： DateBox验证没有'工作，这是一个我们必须经历的问题！同时我在同一个处理程序上添加了一个新的消息处理

编辑4：（最后一个！）

我终于找到了每个小部件类型的工作解决方案，日期必须包含一个'2'（我认为这将是几年的真实;-)我显示整个doGet函数，因为我在这里做了一些其他更改在那里...当fileUpload小部件填入最后位置（不知道为什么）时效果最好，并且在某些情况下需要重新修改textBow以获得验证，但在大多数情况下它应该正常工作。
