前端JS Ajax 调用Java Axis的 web服务

/* 此方法为Ajax 调用Java Axis的web服务,调用举例如下:
callAxisWsPost("远程方法名", new Array("参数名1","参数名2"...), new Array(参数值1,参数值2...),
                         "wsdl地址",
                         "命名空间", function (result) {
                             //Ajax完成后的回调处理,result为服务端返回结果
                         }, function () {
                             //Ajax加载时的处理,如弹出loading遮罩层,提交按钮禁用等
                         });
*/
