删除JSP变量之间的间距 [英] Remove Spacing between JSP variables
问题描述
这个jsp调用之间的间隔有问题
have a problem with the spacing between this jsp calls
<tr>
<%=Constants.getTextInput("", Texts.RNG_IDENT_MSG, "", "", 19)%>
<%=Constants.getTextInput("", Texts.RNG_IDENT_MSG_UNTIL, "", "", 19)%>
</tr>
在屏幕中间有一个空格，我想删除它。
有人可以帮我吗？
In the screen there's a space between them, that i want to remove. Can someone help me?
我试过css和其他格式，但仍然没有。
P.S. i tried css and other formats but still nothing.
PS2：这是一个HTML页面，getTextInput它是一个函数来创建一个盒子。 b $ b
P.S.2: This is in a HTML page and getTextInput it's a function to "create" a box
推荐答案
您可以使用指令 trimDirectiveWhitespaces
$ b
You can use the directive trimDirectiveWhitespaces
<%@ page trimDirectiveWhitespaces="true"%>
这应该会消除动作，脚本和指令之间的空白。
This should remove white spaces between actions, scriptlets and directives.
下面是我在Glassfish 4.0上获得的一个例子： $ b
Here an example of what i get on Glassfish 4.0:
with<％@ page trimDirectiveWhitespaces = jsp中的true％>
with <%@ page trimDirectiveWhitespaces="true"%> in the jsp
<%@ page trimDirectiveWhitespaces="true"%>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<table>
<tr>
<%="1111111111"%>
<%="2222222222"%>
<c:out value="c:out"></c:out>
<c:out value="LOOP"></c:out>
<c:forEach begin="1" end="5" step="1" var="y">
${'qqqqq'} ${'RRR'}
<c:out value="c:out"></c:out>
<% out.println("InTheLoop"); %>
</c:forEach>
</tr>
</table>
</body>
</html>
浏览器中收到的源代码：
Source code received in browser:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<table>
<tr>
11111111112222222222c:outLOOPqqqqqRRRc:outInTheLoop
qqqqqRRRc:outInTheLoop
qqqqqRRRc:outInTheLoop
qqqqqRRRc:outInTheLoop
qqqqqRRRc:outInTheLoop
</tr>
</table>
</body>
</html>
与上面相同的JSP代码，但加上<％ @ page trimDirectiveWhitespaces =false％>
或 without trimDirectiveWhitespaces 在所有
中生成浏览器中收到的以下代码：
The same JSP code as above but with <%@ page trimDirectiveWhitespaces="false"%>
Or without trimDirectiveWhitespaces at all
produce the folowing code received in browser:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<table>
<tr>
1111111111
2222222222
c:out
LOOP
qqqqq RRR
c:out
InTheLoop
qqqqq RRR
c:out
InTheLoop
qqqqq RRR
c:out
InTheLoop
qqqqq RRR
c:out
InTheLoop
qqqqq RRR
c:out
InTheLoop
</tr>
</table>
</body>
</html>
所以trimDirectiveWhitespace =true：
- 您可以删除动作，脚本，表达式，指令之间的空格。 但是，您不能删除其他html标记之间的空格
- you can remove whitespaces between actions, scriptlets, expressions, directives.
- But you can NOT remove whitespaces between other html tags
