jquery的this的使用

jquery的this的使用

this可以重写'父类'的方法

var EditView = function(){

调用重写的createCusView方法

var EditView = function(){
this.uploadUrl = getUploadUrl();
 function getUploadUrl() {
        var serviceUrl = $Core.SERVICEPATH();
        var preffix = serviceUrl.substring(0,serviceUrl.lastIndexOf("cnten"));
        var uploadUrl = preffix + "zuul/plugs/attachment/fileUpload";
        return uploadUrl;
    }
}

var _self = new EditView();
$(function () {
_self.uploadUrl
});
