node.js executing server side function from client side

由 谁都会走 提交于 2019-12-08 07:28:51
问题 I have the server.js file on server side and the index.html on client side. I need to call a function from the server side through maybe a button or something on the index.html and get a feedbak on the index.html that the function was executed. In the future I would also like to pass over a variable to the server side from client side. I'm rather new to node.js. Hopefully someone can help me on this. 回答1: Node.js is no different than any other server side technology: it's not client side. If

Image cropping/resizing before sending to a server

由 霸气de小男生 提交于 2019-12-08 04:43:30
问题 I am searching for a solution that will allow a user to upload an image, crop the image, and then send the updated image to the server. Basically, I would like to handle all the editing client side and only send the new, smaller, thumbnail to the server. How can I do this? I have seen this is possible with Flash, but I am looking for alternative solutions. 回答1: Are you restricted to certain browsers? Using HTML5, here is a proof of concept from Anand Venkataraman.

Client Side Encryption - Any recommendations / best practices - Point me in the right direction?

问题 We have a requirement to encrypt data client side to ensure a 'secure' channel exists between our client's browser and a vendor. Basic premise is: Vendor generates a public / private keypair: VendorPub and VendorPriv Our clients enter sensitive data. On submit the javascript on the form encrypts the sensitive portions of the data, what gets submitted to our server is VendorPub(SensitiveData). We submit that package to our vendor as VendorPub(SensitiveData), only they can make use of that data

How to localise static website text from translations stored in a database?

由 时光总嘲笑我的痴心妄想 提交于 2019-12-08 02:54:17

Sign SOAP request on client-side with Spring

由 [亡魂溺海] 提交于 2019-12-08 01:42:57
问题 I have read the Spring doc regarding Securing your Web services with Spring-WS but it looks for me as if the article is just regarding server side and not client side. Indeed, it is working fine for server side with Wss4jSecurityInterceptor but I need to sign a request to an external Web service. So, first question. Am I right and chapter 7 of Spring Web Services documentation just apply to server side? Second. It is possible, to add security, like signed headers, to SOAP requests on client

问题 I have 2 chekboxes on a page. There are wrapped in a table cell each within their own row. Doing a document.getElementById('chk1_FEAS~1005') returns the element but document.getElementById('chk5_STG2~1005') is null. For what reasons could this be happening?

Can the server use a file from a client without uploading it to the server? ASP.NET

由 只愿长相守 提交于 2019-12-07 14:24:36
问题 I was wondering, at the moment, the client uploads a file to a directory on the server where the server can then use the file (csv file) to update a SQL database. Is that the only way the server can use that file? For it to first be uploaded to the server? Or can you use that file without uploading it to a directory of the server?
