【问题标题】:add validation inside an Ionic creator page在 Ionic 创建者页面中添加验证
【发布时间】:2017-06-27 13:40:01
【问题描述】:

我已经获得了一个具有这种层次结构的 Ionic 创建者项目:

-index.html
-templates (directory)
    --signup.html
    --signin.html
-lib (directory)
-css (directory)
-js (directory)

所以...如何向 signup.html 页面添加简单的验证?这是所有 signup.html 代码,我该如何修改它?我希望所有字段都是必填项。

<ion-view title="Registrazione" id="page2" style="background-color: rgb(181, 210, 253);">

    <ion-content padding="true" scroll="false" class="has-header">

        <form id="registrazione-form3" name="formSignup" class="list" method="POST" action="SignupServlet" novalidate>
            <ion-list id="registrazione-list1">
                <label class="item item-input" id="registrazione-input5">
                    <span class="input-label">Nome:</span>
                    <input placeholder="" type="text" name="nome" >
                </label>
                <label class="item item-input" id="registrazione-input6">

                Yeah this is just a demo showing how views can be shown without tabs, then you can navigate
                to views within tabs. Additionally, only one set of tabs needs to be written for all of the different views that should go inside the tabs. (Compared to written the same tab links in the footer of every view that's in a tab.)
              </p>
              <p>
                There's no username/password, just click
                the Sign-In button back a the sign-in view.

              <p>

    【讨论】:

    • 好的,但是我在哪里插入这段代码的每一段?能详细点吗?
    • 您需要在 app.js 中添加的第一个代码和平。第二个是 css 文件,您可以创建您的 custom.css 并将该文件的路径包含到 index、html 文件和最后一个一个是 html 页面,您可以将其用作您的 signup.html 并删除您不需要的额外代码..我希望这可能对您有所帮助..!!
