Use ANT and YUI to compress js

Because many projects use JavaScript, JavaScript is compressed to improve system efficiency.

To successfully compress multiple JavaScript files, you must go through the following two steps.

1. Merge multiple JavaScript codes into one js.

2. Compress and the following JavaScript code.

Ant configurations used mainly include:

<Property name = "root" value = "WebRoot"> </property>
<Property name = "js" value = "$ {root}/js"> </property>
<Property name = "map_function_js" value = "$ {js}/mapfunc"> </property>
<Property name = "lib" value = "lib"/>
<Property name = "build" value = "build"> </property>
<Property name = "war" value = "war"> </property>
<Property name = "war.info" value = "$ {war}/WEB-INF"> </property>
<Property name = "war. lib" value = "$ {war.info}/lib"> </property>
<Property name = "war. classes" value = "$ {war.info}/classes"> </property>
<Property name = "project. name" value = "zjmap"> </property>
<Property name = "charset" value = "UTF-8"/>
<Property name = "src" value = "src"/>
<Target name = "create build directory">
<Mkdir dir = "$ {build}"/>
</Target>
