HTML表单如何创建？form标签的action和method属性是什么？

要创建一个html表单，必须使用

标签并设置action和method属性，1. action属性指定数据提交的url，2. method属性定义提交方式为get或post，3. 表单内可包含input、textarea、select、button等元素，4. get将数据附加在url中，适合非敏感小数据，5. post将数据放在请求体中，适合敏感或大量数据，6. 服务器端需用php、python等语言处理提交的数据，7. 其他常用元素包括radio、checkbox、file、date、datalist、fieldset、label等，完整表单应结合这些元素实现功能完整且可访问性强的用户输入界面。

创建一个HTML表单，核心在于使用

标签包裹住所有表单元素。

标签的

action

属性指定了表单数据提交到的服务器端URL，而

method

属性则定义了提交数据的方式，通常是

GET

或

POST

。

标签是表单的容器，

action

属性指定了处理表单数据的服务器端脚本的 URL，

method

属性定义了提交表单数据的方式。

要创建一个HTML表单，你需要使用

标签，并在其中包含各种表单元素，如输入框

、文本区域

</pre>
<div class="contentsignin"></div>
</div>
<p>、下拉列表</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;"></pre>
<div class="contentsignin"></div>
</div>
<p>、按钮</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;"><button></pre>
<div class="contentsignin"></div>
</div>
<p>等。</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;"></pre>
<div class="contentsignin"></div>
</div>
<p>标签有两个关键属性：</p>
<p><strong></p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">action</pre>
<div class="contentsignin"></div>
</div>
<p></strong>:  指定了当<span class="wpcom_tag_link"><a href="https://www.chuangxiangniao.com/p/tag/biaodantijiao" title="表单提交" target="_blank">表单提交</a></span>时，数据将被发送到的服务器端URL。例如，</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">action="/submit-form"</pre>
<div class="contentsignin"></div>
</div>
<p>表示数据将被发送到服务器上的</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">/submit-form</pre>
<div class="contentsignin"></div>
</div>
<p>路径。</p>
<p><strong></p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">method</pre>
<div class="contentsignin"></div>
</div>
<p></strong>:  定义了提交表单数据时使用的HTTP方法。常用的方法有</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">GET</pre>
<div class="contentsignin"></div>
</div>
<p>和</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">POST</pre>
<div class="contentsignin"></div>
</div>
<p>。</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">GET</pre>
<div class="contentsignin"></div>
</div>
<p>:  将表单数据附加到URL的查询字符串中。  例如：</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">?name=John&email=john@example.com</pre>
<div class="contentsignin"></div>
</div>
<p>。 适用于数据量小且不敏感的情况。</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">POST</pre>
<div class="contentsignin"></div>
</div>
<p>:  将表单数据包含在HTTP请求的主体中。  适用于数据量大或包含敏感信息的情况。</p>
<p>一个简单的HTML表单示例：</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class='brush:html;toolbar:false;'></pre>
<div class="contentsignin"></div>
</div>
<p>这个例子创建了一个包含姓名和<span class="wpcom_tag_link"><a href="https://www.chuangxiangniao.com/p/tag/youxiang" title="邮箱" target="_blank">邮箱</a></span>输入框的表单。 当用户点击“提交”按钮时，表单数据将通过POST方法发送到服务器上的</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">/submit-form</pre>
<div class="contentsignin"></div>
</div>
<p>路径。</p>
<h3>如何处理表单提交后的数据？</h3>
<p>服务器端需要编写相应的脚本（例如，使用PHP、Python、Node.js等）来接收和处理表单提交的数据。  脚本需要能够读取</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">action</pre>
<div class="contentsignin"></div>
</div>
<p>属性指定的URL接收到的数据，并进行相应的处理，例如存储到数据库、发送邮件等。  具体如何处理取决于你的应用需求。</p>
<h3>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">GET</pre>
<div class="contentsignin"></div>
</div>
<p>和</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">POST</pre>
<div class="contentsignin"></div>
</div>
<p>方法有什么<span class="wpcom_tag_link"><a href="https://www.chuangxiangniao.com/p/tag/qubie" title="区别" target="_blank">区别</a></span>？应该选择哪个？</h3><div class="code" style="position:relative;padding:0px;margin:0px"><pre class="brush:php;toolbar:false;">GET</pre><div class="contentsignin"></div></div><p>和</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">POST</pre>
<div class="contentsignin"></div>
</div>
<p>是HTTP协议中用于提交数据的两种主要方法，它们之间存在一些关键区别：</p>
<p><strong>数据可见性：</strong>  </p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">GET</pre>
<div class="contentsignin"></div>
</div>
<p>方法将数据附加到URL中，因此数据在URL中是可见的。  </p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">POST</pre>
<div class="contentsignin"></div>
</div>
<p>方法将数据包含在HTTP请求的主体中，因此数据对用户是不可见的。<strong>数据长度限制：</strong>  </p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">GET</pre>
<div class="contentsignin"></div>
</div>
<p>方法对URL的长度有限制，通常为2048个字符。  </p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">POST</pre>
<div class="contentsignin"></div>
</div>
<p>方法没有数据长度限制。<strong>安全性：</strong>  </p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">GET</pre>
<div class="contentsignin"></div>
</div>
<p>方法不适合提交<span class="wpcom_tag_link"><a href="https://www.chuangxiangniao.com/p/tag/minganshuju" title="敏感数据" target="_blank">敏感数据</a></span>，因为数据在URL中可见，容易被截获。  </p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">POST</pre>
<div class="contentsignin"></div>
</div>
<p>方法更适合提交敏感数据，因为数据在HTTP请求的主体中，相对更安全。<strong>用途：</strong>  </p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">GET</pre>
<div class="contentsignin"></div>
</div>
<p>方法通常用于获取数据，例如搜索、分页等。  </p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">POST</pre>
<div class="contentsignin"></div>
</div>
<p>方法通常用于提交数据，例如创建、更新、删除等。</p>
<p>选择哪种方法取决于你的应用场景。  一般来说，如果需要提交敏感数据或数据量较大，应该选择</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">POST</pre>
<div class="contentsignin"></div>
</div>
<p>方法。  如果只是获取数据，可以选择</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">GET</pre>
<div class="contentsignin"></div>
</div>
<p>方法。  但需要注意的是，</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">GET</pre>
<div class="contentsignin"></div>
</div>
<p>方法不应该用于执行会修改服务器状态的操作，例如删除数据。</p>
<h3>除了</p>
<div class="code" style="position:relative;padding:0px;margin:0px">
<pre class="brush:php;toolbar:false;">input</pre>
<div class="contentsignin"></div>
</div>
