问题描述
如题,在Bootstrap
中,如何为一个文本框添加图标呢?比如有实现一个用户名的文本框,如下图:
方案一
参考官方的示例代码(无需写其他的CSS样式):
<form class="form-inline" role="form">
<div class="form-group has-success has-feedback">
<label class="control-label" for="inputSuccess4"></label>
<input type="text" class="form-control" id="inputSuccess4">
<span class="glyphicon glyphicon-user form-control-feedback"></span>
</div>
</form>
方案二
不使用 Bootstrap
实现,
HTML:
<div class="inner-addon left-addon">
<i class="glyphicon glyphicon-user"></i>
<input type="text" class="form-control" />
</div>
CSS:
/* enable absolute positioning */
.inner-addon {
position: relative;
}
/* style icon */
.inner-addon .glyphicon {
position: absolute;
padding: 10px;
pointer-events: none;
}
/* align icon */
.left-addon .glyphicon { left: 0px;}
.right-addon .glyphicon { right: 0px;}
/* add padding */
.left-addon input { padding-left: 30px; }
.right-addon input { padding-right: 30px; }

使用 Bootstrap
:
<div class="form-group has-feedback">
<label class="control-label">Username</label>
<input type="text" class="form-control" placeholder="Username" />
<i class="glyphicon glyphicon-user form-control-feedback"></i>
</div>
方案三
HTML:
<div class="col-md-4">
<input class="form-control" type="search" />
<span class="glyphicon glyphicon-search"></span>
</div>
CSS:
.form-control {
padding-right: 30px;
}
.form-control + .glyphicon {
position: absolute;
right: 0;
padding: 8px 27px;
}
方案四
<div class="form-group">
<label class="control-label">Start:</label>
<div class="input-group">
<input type="text" class="form-control" aria-describedby="start-date">
<span class="input-group-addon" id="start-date"><span class="glyphicon glyphicon-calendar"></span></span>
</div>
</div>
方案六
CSS:
input {
border:solid 1px #ddd;
}
input.search {
padding-left:20px;
background-repeat: no-repeat;
background-position-y: 1px;
background-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABQAAAASCAYAAABb0P4QAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsMAAA7DAcdvqGQAAADbSURBVDhP5ZI9C4MwEIb7//+BEDgICA6C4OQgBJy6dRIEB6EgCNkEJ4e3iT2oHzH9wHbpAwfyJvfkJDnhYH4kHDVKlSAigSAQoCiBKjVGXvaxFXZnxBQYkSlBICII+22K4jM63rbHSthCSdsskVX9Y6KxR5XJSSpVy6GbpbBKp6aw0BzM0ShCe1iKihMXC6EuQtMQwukzPFu3fFd4+C+/cimUNxy6WQkNnmdzL3NYPfDmLVuhZf2wZYz80qDkKX1St3CXAfVMqq4cz3hTaGEpmctxDPmB0M/fCYEbAwZYyVKYcroAAAAASUVORK5CYII=);
