How do we redirect the user from one page to another using jQuery?

jQuery is not necessary, and window.location.replace(…) will best simulate an HTTP redirect.

These client-side technologies don’t involve any server processing. Instead, the complete application is downloaded to the client browser, which executes it locally. The greatest problem with client-side technologies is that they aren’t supported equally by all browsers and operating systems. One of the reasons that web development is so … Click here to continue…..

Although you can use a generic bind function to capture any event using an event name specified as a string, jQuery also provides dedicated methods for common events, such as click, blur, and submit. As demonstrated earlier, you tell jQuery what to do when the event occurs by passing in a function. The function can be anonymous, as in the example you saw in the section “The jQuery Function” earlier in the chapter, or you can also pass a named function as an … Click here to continue…..
