【前端】【探究】HTML input类型为file时如何实现自定义文本以更好的美化

Solution

We can use a button to select file and use a text box to show selected file’s name , instead of file type input.

This does not mean that we discard input of file type , just hide it and use other elements to control it , it’s still the one that actually works.(这并不意味着我们抛弃了文件类型的 “input”,只是隐藏了它并使用其他元素来控制它,它仍然是真正起作用的)

Example

1.Use Button to select file

Use display:none to hiden file type input


When we click on the button with the id selectFile, Javascript will get the element of file type input, and then execute its click event(点击事件).

2.Use a box to show selected file’s name

You can use a text type inputp tags、 div tags and so on.

Now,I’ll use a text type input as case to write a demo

Prefor a text type input and set it read only, the code is as follows:


Now, we have to thinking about how to get the selected file’name.

Obviously, we need to read the name of the uploaded file from the input of the file type, the code is as follows:


tips : you can use outline:none to make the element outline hiden.

The complete code
