javascript - validation on textbox depending on selectbox selected value change event in jquery -

-

jquery में selectbox चयनित मान परिवर्तन की घटना के आधार पर पाठ बॉक्स पर सत्यापन।

लेकिन अगर मैं 'एनआईडी' का चयन करता हूं तो पहले 'पीएसटी' की लम्बाई में बदल जाता हूं, जब मैं 'पीएसटी' का चयन करता हूं और फिर 'एनआईडी' लम्बाई के भाग में काम करता हूं। / P> 

  $ (document) .ready (function () {$ ('# seIdproof')। परिवर्तन (फ़ंक्शन () {var PFID = $ ('# seIdproof')। Val (); $ ('#seCustomerId')। वाल (''); अगर (पीएफआईडी == 'पीएसटी') {$ ('# seCustomerId') कुंजीप (फ़ंक्शन (ई) {var len3 = $ (this) .val () लंबाई; यदि (len3 & gt; 6) {चेतावनी ("यह आईडी प्रमाण संख्या मान्य नहीं है, कृपया मान्य संख्या दर्ज करें"); $ (यह) .val ('');}})}} अगर (पीएफआईडी == 'एनआईडी') {$ ('# seCustomerId') कुंजीप (कार्य (ई) { Var len1 = $ (this) .val ()। लंबाई; यदि (len1 & gt; 11) {चेतावनी ("यह आईडी प्रमाण संख्या मान्य नहीं है, कृपया मान्य संख्या दर्ज करें।"); $ (This) .val ( ''); }}); }}); });

क्या कोई सुझाव दे सकता है।

धन्यवाद

उपयोग की कोशिश करें .keyup (फ़ंक्शन (ई) {और इस कोड को जोड़ें e.preventDefault ()

रिटर्न कोड की लाइनों को हटाएं और केवल $ डाल (this) .val ('');

I am trying to use the ASP.NET signal for the first time - here's what I did: created a new web Has been added to the project and the following signal R packages: I have created the following category: [Hub-name ("chat")] Public class ChatHub: Hub {Public Zero Halo () {Clients.All.hello ( ); }} and the following startup configuration: public partial class startup {public zero configuration (IAppBuilder app) {configure (app); App.MapSignalR (); }} However, whenever I navigate localhost: (port) / api / signalr / chat I get the following error: Protocol error: Unknown transport.

Camel ProducerTemplate possible memory leak -

To some degree, this is a bit of a shot in the dark, but we have a process that is dramatically slow One day's course we have found that all the things running on the fuses begin to draw, but when we are running a specific process, JPPropellers are going on, I have found that the increase in magnetic usage increases over time. . Org.apache.camel.ProductTemplate.Send So my main question is, is the way in which the manufacturer product is being used here which is wrong / can this be a problem? exchange foo = new DefaultExchange (getCamelContext (), ExchangePattern.InOnly); Foo.getIn () setBody (obj). Root R = Exchange .getContext (). GetRoute ("do_something_fun"); Creator Template Template = exchange.getContext () CreateProducerTemplate (); Template.send (r.getEndpoint (), foo); Generally, you should not create a productive template on each request as described here: / P> However, because I do not have a complete picture of your application, so you can cr...

javascript - Adhering to a max length setting with jshint -

-
I get several recommendations to compile a maximum of 80 characters when writing javascript, e.g. Google, NPM, Node. JS, Crockford In some cases, though, I do not think how best to do this. MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase', function (mistake, database) {if (err)} {throw error;} db = database;}); This will throw a jshint warning because it exceeds 80 characters. Now, do you choose to ignore the warning in this example, or instead choose an option for a solution like MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase' , Function (err, database) {if (err) {throw error;} db = database;}); If you can reuse the url variable So, great option if this is a shot, as is often such a call, I would probably do something like this ... / * jslint sloppy: true, white: true, browser: True, maxlen: 80 * / / * global mongo client * / var dbarhh, db; DbErrHand = function (mistake, database) {if (err) {throw error; } ...
