创建一个简单的input标签实现网页上的输入框效果。
添加输入框的步骤如下:
<input>标签用于搜集用户信息。根据不同的 type 属性值,输入字段拥有很多种形式。输入字段可以是文本字段、复选框、掩码后的文本控件、单选按钮、按钮等等。
工具:编辑器、浏览器
1、创建一个简单的input标签实现网页上的输入框效果,代码如下:
1 First name: <input type="text" name="fname" />2 Last name: <input type="text" name="lname" />3 <input type="submit" value="Submit" />
2、以上代码中type=text是文本的输入框,type=submit是一个提交按钮,运行的效果如下图:
添加多个输入框的方法如下:
<input id="input_template" name="name" maxlength="7" type="text" style="width: 120px">
<!-- 这里是一个模版,追加的时候用来克隆的。 -->
$('#addBtn').bind('click', function() {
var input_ = $("#input_template").clone()
$("#input_container").append(input_)
})
<!-- 需要注意的是,在追加的时候,或者追加之后,把追加元素imput的name和id重置一下。 -->
演示图如下:
用到的是js和正则表达式代码如下:

<input type="button" value="全额" style="width:48px height:42px background:#FFF border:1px solid #D5d5d5border-radius: 3px color:#98999B" />这个是那个全额按钮的代码
哪个input 框有很多中切法,例如让前面的input文本框有左,上,下边框,把右边的元字截个图片拼一起
