我想要一个类似 this 的搜索图标在文本框的开头呈现，我无法使以下内容正常工作。请帮忙。
html:
<body class="claro" data-maq-flow-layout="true" data-maq-comptype="desktop" data-maq-ws="collapse" style="margin-top:0" id="myapp" data-maq-appstates="{}">
<div id="top_bar">
<div style="width: 900px; height:50px; margin-left: auto; margin-right: auto;">
<a href="/" class="logo logo_a">
<div class="logo">
</div>
</a>
<div class="midArea_div">
<div class="searchBox_div">
<input type="text" data-dojo-type="dijit.form.TextBox" class="searchBox"></input>
</div>
</div>
</div>
</div>
<div id="top_bar_divider"></div>
<div data-dojo-type="dijit.layout.BorderContainer" persist="false" gutters="true" style="min-width: 1em; min-height: 1px; z-index: 0; width: 600px; height: 687px; margin-left: auto; margin-right: auto;" design="headline">
<div data-dojo-type="dijit.layout.ContentPane" extractContent="false" preventCache="false" preload="false" refreshOnShow="false" region="center" splitter="false" maxSize="Infinity">
</div>
</div>
</body>
js:
require([
"dijit/dijit",
"dojo/parser",
"maqetta/space",
"maqetta/AppStates",
"dijit/layout/BorderContainer",
"dijit/layout/ContentPane",
"dijit/form/TextBox"
]);
CSS:
html,body {
height: 100%;
width: 100%;
}
.logo_a{
background:url("icon1.png");
}
.logo{
width:60px;
height:50px;
display:inline-block;
vertical-align:middle;
}
.logo_a:active{
background-position:0 1px;
}
#top_bar{
padding:0px;

width:100%;
}
.searchBox{
height: 30px;
width: 400px;
padding-left:30px;
font-size:20px;
}
.searchBox_div{
display:inline-block;
verticle-align:middle;
background: #FFF url("http://app.maqetta.org/maqetta/user/CoQ/ws/workspace/project1/search_icon.png") no-repeat scroll 5px 6px;
}
.midArea_div{
margin-left: 100px;
verticle-align:middle;
display:inline-block;
}
.searchIcon{
}
最佳答案
您当前的方法不起作用，因为文本框位于其背景之上，因此不可见。您可以在 .searchBox_div 上使用伪元素来执行此操作(在 <= IE8 中不起作用)。
.searchBox_div {
position:relative;
}
.searchBox_div:before {
content:"";
display:block;
position:absolute;
background: url(http://app.maqetta.org/maqetta/user/CoQ/ws/workspace/project1/search_icon.png) no-repeat center center;
width:24px;
height:24px;
left:4px;
top:50%;
margin-top:-12px;
z-index:1;
}
或者，您可以将这些样式应用于 .searchBox_div 中的另一个 div，以增加标记为代价来解决 IE8 问题。
HTML
<div class="midArea_div">
<div class="searchBox_div">
<input type="text" data-dojo-type="dijit.form.TextBox" class="searchBox"></input>
<div class="overlay"></div>
</div>
</div>
CSS
.searchBox_div {
position:relative;
}
.overlay {
position:absolute;
background: url(http://app.maqetta.org/maqetta/user/CoQ/ws/workspace/project1/search_icon.png) no-repeat center center;
width:24px;
height:24px;
left:4px;
top:50%;
margin-top:-12px;
z-index:1;
}
