HTML Input URL autocomplete用法及代码示例

HTML DOM中的DOM输入URL自动完成属性用于设置或返回输入URL字段的自动完成属性的值。自动完成属性用于指定自动完成属性具有“on”值还是“off”值。当autocomplete属性设置为on时，浏览器将根据用户之前输入的内容自动完成值。

用法:

它返回输入URL自动完成属性。
```
urlObject.autocomplete
```
它用于设置输入URL自动完成属性。
```
urlObject.autocomplete = "on|off"
```

属性值：它包含下面列出的两个值：

on:它是默认值。它会自动完成值。
off:它定义了用户应填写URL输入字段的值。它不会自动完成值。

返回值：它返回一个表示自动完成状态的字符串值。

示例1：本示例说明了如何返回属性。
