1、先上效果图
2、调用方式
<link href="/Styles/tagsinput.css" rel="external nofollow" rel="stylesheet" type="text/css" /> <script src="http://www.jb51.netScripts/jquery-1.4.1.min.js" type="text/javascript"></script> <script src="http://www.jb51.netScripts/jquery.tagsinput.js" type="text/javascript"></script> <script type="text/javascript"> $(function () { $("#txtTags").TagsInput({ usedTags: "css|js|jquery|html|C#|.net|web", hotTags: "hotTag1|hotTag2|hotTag3|hotTag4", tagNum: 10, maxWords: 10 }); }); </script>
html页面调用
<input type="text" value="逗号|分号|空格|Tab|回车键" name="txtTags" id="txtTags" />
3、tagsinput.css样式
.clearfix:after { clear: both; content: " "; display: block; height: 0; } .tags-wrapper { width: 500px; position:relative; } #addTagWrap { background: none repeat scroll 0 0 #FFFFFF; border: 1px solid #D9D9D9; padding: 0 5px; } #addTagWrap .inner-tag-wrapper,.layer-tag-name { background: none repeat scroll 0 0 #40A8CD; border-radius: 3px; color: #FFFFFF; float: left; height: 26px; line-height: 26px; margin: 4px 6px 0 0; padding: 0 5px 0 10px; white-space: nowrap; } #addTagWrap .inner-tag-close { color: #A0D4E6; font-family: "宋体" ,sans-serif; margin-left: 4px; text-decoration: none; } #tagInput { background: none repeat scroll 0 0 #FFFFFF; border: medium none; margin: 0; height: 24px; line-height: 24px; overflow: hidden; padding: 5px; width: 215px; } #tagInput:focus{ outline:none } .layer-tags-wrapper { border: 1px solid #DADADA; border-top:0; overflow: auto; position:absolute; left:0; right:0; display:none; background: none repeat scroll 0 0 #FFFFFF; } .layer-tags-wrapper .layer-tags-box { padding: 0 5px; } .layer-tags-wrapper .layer-tags-left { float: left; text-align: center; padding-right: 5px; margin-top: 4px; height: 26px; line-height: 26px; } .layer-tags-wrapper .layer-tags-right { overflow: auto; } .layer-tags-wrapper .layer-tag-name { padding-right: 10px; text-decoration: none; } .layer-tags-foot { height: 30px; line-height: 30px; color: #999999; padding-left:5px; } .layer-tags-foot-top { margin-top:5px; border-top:1px dotted #C9C9C9; } .message-box { background: none repeat scroll 0 0 rgba(0, 0, 0, 0.35); color: #FFFFFF; width: 300px; min-height: 50px; line-height: 50px; top: 50%; left: 50%; margin-top: -50px; /*注意这里必须是DIV高度的一半*/ margin-left: -150px; /*这里是DIV宽度的一半*/ position: fixed !important; /*FF IE7*/ position: absolute; /*IE6*/ z-index: 999; text-align: center; border-radius: 5px; }
