html
<div id="some-div">
<a href="#"><img class='round_border type_border' src='http://www.jewsnews.co.il/wp-content/uploads/2013/08/Donald_Duck.gif'/>

position:relative
}
#some-element {
width:100px;
height:100px;
border: 1px solid orange;
display: none;
font-size: 10px;
bottom: 0px;
left: 0px;
right: 0px;
text-align: center;
text-transform: uppercase;
position: absolute;
top:0;
left:0;
background:rgba(255,79,50,.5);
color:Black !important;
margin-top:2px;
border:1px solid gray;
-webkit-border-radius: 500px;
-moz-border-radius: 500px;
border-radius: 500px;
}
#some-div:hover #some-element {
display: block;
position: relative;
cursor: pointer;
color:#FFFFFF;
}
a{
position: relative;
}
.type_border {
width: 100px;

<script>
var string = "<span>this is span</span>new line";
var anchors = $('<div/>').append(string).find('span').text();
console.log(anchors);

div 看起来像
<div>
<span>this is span</span>
new line
</div>
输出：-
this is span

<div id="grid">
<script id="rowTemplate" type="text/x-kendo-tmpl">
<tr>

<td> #= FirstName # </td>
<td> #= LastName # </td>
</tr>
</script>
<script id="detailTemplate" type="text/x-kendo-tmpl">
<p>detail stuff</p>
</script>
</div>
数据源 :
dataSource: {
data: [
{
id:"",
FirstName: "Joe",
LastName: "Smith"
},
{
id:"1",
FirstName: "Jane",
LastName: "Smith"
}]
},
