有没有一种快速的方法来创建一个输入文本元素，在右边有一个图标，以清除输入元素本身(如谷歌搜索框)?
我环顾四周，但我只发现如何把一个图标作为输入元素的背景。有jQuery插件或其他什么?
我想在输入文本元素内的图标，类似于:

使用简单的绝对定位——这并不难。
jQuery:
$('span').click(function(){ $('input', $(this).parent()).val(''); }) <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div style="position:relative; width:min-content;"> <input> <span style="position:absolute;right:10px">x</span> </div> <div style="position:relative; width:min-content;"> <input> <span style="position:absolute;right:10px">x</span> </div> <div style="position:relative; width:min-content;"> <input> <span style="position:absolute;right:10px">x</span> </div>
香草JS:
var spans = document.getElementsByTagName("span"); function clickListener(e) { e.target.parentElement.getElementsByTagName("input")[0].value = ""; } for (let i = 0; i < spans.length; i++) { spans[i].addEventListener("click", clickListener); } <div style="position:relative; width:min-content;"> <input> <span style="position:absolute;right:10px">x</span> </div> <div style="position:relative; width:min-content;"> <input> <span style="position:absolute;right:10px">x</span> </div> <div style="position:relative; width:min-content;"> <input> <span style="position:absolute;right:10px">x</span> </div>
像这样的事情?? Jsfiddle演示
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css">
.searchinput{
display:inline-block;vertical-align: bottom;
width:30%;padding: 5px;padding-right:27px;border:1px solid #ccc;
outline: none;
}
.clearspace{width: 20px;display: inline-block;margin-left:-25px;
}
.clear {
width: 20px;
transition: max-width 0.3s;overflow: hidden;float: right;
display: block;max-width: 0px;
}
.show {
cursor: pointer;width: 20px;max-width:20px;
}
form{white-space: nowrap;}
</style>
</head>
<body>
<form>
<input type="text" class="searchinput">
</form>
<script src="jquery-1.11.3.min.js" type="text/javascript"></script> <script>
$(document).ready(function() {
$("input.searchinput").after('<span class="clearspace"><i class="clear" title="clear">✗</i></span>');
$("input.searchinput").on('keyup input',function(){
if ($(this).val()) {$(".clear").addClass("show");} else {$(".clear").removeClass("show");}
});
$('.clear').click(function(){
$('input.searchinput').val('').focus();
$(".clear").removeClass("show");
});
});
</script>
</body>
</html>
你可以使用一个带有图像样式的重置按钮…
<form action="" method="get">
<input type="text" name="search" required="required" placeholder="type here" />
<input type="reset" value="" alt="clear" />
</form>
<style>
input[type="text"]
{
height: 38px;
font-size: 15pt;
}
input[type="text"]:invalid + input[type="reset"]{
display: none;
}
input[type="reset"]
{
background-image: url( http://png-5.findicons.com/files/icons/1150/tango/32/edit_clear.png );
background-position: center center;
background-repeat: no-repeat;
height: 38px;
width: 38px;
border: none;
background-color: transparent;
cursor: pointer;
position: relative;
top: -9px;
left: -44px;
}
</style>
在这里查看它的实际操作:http://jsbin.com/uloli3/63
我已经在CSS中创建了一个可清除的文本框。它不需要javascript代码使其工作

您可以使用这些命令(没有引导)。
Array.from(document.querySelectorAll('.search-field')).forEach(field => { field.querySelector('span').addEventListener('click', e => { field.querySelector('input').value = ''; }); }); :root { --theme-color: teal; } .wrapper { width: 80%; margin: 0 auto; } div { position: relative; } input { background:none; outline:none; display: inline-block; width: 100%; margin: 8px 0; padding: 13px 15px; padding-right: 42.5px; border: 1px solid var(--theme-color); border-radius: 5px; box-sizing: border-box; } span { position: absolute; top: 0; right: 0; margin: 8px 0; padding: 13px 15px; color: var(--theme-color); font-weight: bold; cursor: pointer; } span:after { content: '\2716'; } <div class="wrapper"> <div class="search-field"> <input placeholder="Search..." /> <span></span> </div> </div>
