jsp页面字符串截取，点击弹出弹出层
1、jsp页面
<!--弹出层js-->
<script type="text/javascript" src="mainpage/js/jquery_dialog.js"></script>
<link rel="stylesheet" type="text/css" href="mainpage/css/jquery_dialog.css" />
<!--base64编码解码-->
<script type="text/javascript" src="${path}/js/Base64-80.js"></script>
<!--截取字符串-->
<script type="text/javascript" src="${path}/js/dealstring.js"></script>
<td title="<s:property value='#vl.virusFileName'/>">
<script type="text/javascript">document.write(dealLn("${vl.virusFileName}",24))</script>
</td>2、dealstring.js
/**
* 字符串带有换行符且长度大于25时 进行处理
* @param text
* @return
*/
function dealLn(text,length){
var strlen = 0;
var s = "";
var str = text;
if(null !=text && text.length>0){
for ( var i = 0; i < text.length; i++) {
//一个汉字2个字符
if (text.charCodeAt(i) > 128) {
strlen += 2;
} else {
strlen++;
}
s += text.charAt(i);
if (strlen >= length) {
text = s + "...";
break;
}
}
}
if(null != str && '' != str && "" != str){
str = encode64(str);
}
//encodeURI(encodeURI(str))
text = "<a style='text-decoration:none;color: black;' onclick=\"JqueryDialog.Open1('详情', '/common/logshow.jsp?message="+str+"',370, 120)\" >"+text+"</a>";
return text;
}3、Base64-80.js，base64编码
见附件
4、logshow.jsp，弹出层的jsp页面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'showLog.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<script language="javascript" type="text/javascript">
$(function(){
//decode64(decodeURI(decodeURI('')));
var ds = '<%=request.getParameter("message")%>';
if(ds!='null' && ds!=null && ''!=ds){
ds = ds.split(" ").join("+");
ds = decode64(ds);
$("#detls").val(ds);
$("#detls").css("display","block");
}else{
$("#detls").css("display","none");
}
});
</script>
</head>
<body>
<textarea id="detls" rows='8' cols='17'
style='width: 350px; height: 100px;display: none;margin-left: 10px;'></textarea>
</body>
