Question

当我在bootstrap 4中使用自定义输入文件时，请勿更改我的输入并且不要显示browse按钮。

<label class="custom-file">
    <input type="file" id="Image" class="custom-file-input">
    <span class="custom-file-control"></span>
</label>

.custom文件

position: relative;
display: inline-block;
max-width: 100%;
height: 2.5rem;
cursor: pointer;

.custom文件输入

min-width: 14rem;
max-width: 100%;
margin: 0;
filter: alpha(opacity=0);
opacity: 0;

.custom文件控制

position: absolute;
top: 0;
left: 0;
right: 0;
z-index: 5;
height: 2.5rem;
padding: .5rem 1rem;
line-height: 1.5;
color: #555;
user-select: none;
background-color: #fff;
border: 1px solid #ddd;
border-radius: .25rem;

Answer 1

The documentation states that you should set the language of the document. For example, setting just:

<html lang="en">

was enough to get it working, unless like in @masud_moni answer, you have specified another language then use that instead of "en".

Answer 2

据我检查过 - 你需要在假元素之前插入：之前和之后 - 然后它就可以了。

.custom-file-control:before{
  content: "Browse";
}
.custom-file-control:after{
  content: "Add files..";
}

Answer 3

尝试使用以下代码。希望它能解决你的问题。它仅在Bootstrap页面的代码示例下给出。

$custom-file-text: (
    placeholder: (
    en: "Choose file...",
    es: "Seleccionar archivo..."
    ),
    button-label: (
        en: "Browse",
        es: "Navegar"
    )
);

Answer 4

关于按钮，您可以在.css文件中指定语言，它将显示：

.custom-file-control:lang(fr)::before{
    content:"PARCOURIR";
}
.custom-file-control:lang(en)::before{
    content:"BROWSE";
}

Answer 5

要在非英语网页中显示自定义文件控件的占位符及其按钮标题，您必须添加到CSS .custom-file-control:before和.custom-file-control:empty::after就像在这个片段中一样。

此时，open issue选择后在自定义控件中获取文件名...您可以应用此处显示的onchange事件解决方法。

/* Valid for any language */
.custom-file-control:before {
	content: "Search";
}
.custom-file-control:empty::after {
	content: "Choose a file...";
}

/* Specific for spanish language */
.custom-file-control:lang(es)::before {
	content : "Buscar";
}
.custom-file-control:lang(es):empty::after {
	content : "Seleccionar un fichero...";
}

Answer 6

我遇到了同样的问题，来到这里寻求解决方案，没有找到它，所以我继续挖掘它：正确的做法是拥有一个div类的自定义文件及其中的输入和标签，而不是标签内的输入。

<div class="custom-file">
    <input type="file" id="Image" class="custom-file-input">    
    <label class="custom-file" for="Image">Select file to upload</label>
</div>

bootstrap 4中的自定义输入文件不显示按钮
