I have an input text box and a search submit button, and when user clicks the Search submit button, I want to redirect user to url http://testsearch/results.aspx?k=<
You can even use the submit button this way:
Semantically submit button is used to submit forms not redirect pages. You should use normal button type for this. However as i showed you can use the submit button too but that is not semantic i think.
The below line prevents the form from being submitted.
return false;
That is what you are missing in your code :)
Thanks
