【JavaScript】获取项目路径地址

在jsp页面顶上面定义

<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"+ request.getServerName() + ":" + request.getServerPort()+ path + "/";
%>

然后JavaScript里面获取

<script type="text/javascript">
        var baseUrl="<%=basePath%>";
</script>

获取的url例如：

request.getScheme() = "http"

request.getServerName() = "localhost"

request.getServerPort() = "8080"

request.getContextPath() = "wms-web-enterprise"

baseUrl = "http://localhost:8080/wms-web-enterprise/"
