On Page Load jQuery Calls Action a second time and White Page

in jQuery Mobile • 5 years ago

We us several libraries including jQuery, UI and Mobile in a C# MVC environment. For some reason when I load my action with jQuery included my page will load fine, then reload calling my controller action a second time, but only shows a white page. When I do not include jQuery or jQuery Mobile it works just fine, but of course no styles or functionality on the page.

I've checked everywhere and do not see jQuery being included more than once and have no idea why it's reloading.

Included Scripts:

jquery-2.2.4.js
jquery-ui-custom.js
jquery.unobtrusive-ajax.js
jquery.mobile-1.4.5.js
CustomMultiSelect.js
jquery.maskedinput.js

Network tab:

A picture of the network tab in your browser's inspector tells us nothing useful.

Probably the best thing in this case would be to post a link to the page, if that is possible.

You've chosen a very strange and difficult to work with combination of libraries. I have never seen anybody successfully combine jQuery UI and jQuery Mobile in the same document.

And you've added unobtrusive-ajax to boot!

Off the topic of the specific problem, but I'd suggest picking one way of doing things.

But it sounds like you forget to prevent the default action of some button or whatnot. (We have to guess, as you didn't tell us much.)

This is just what my company does.

You were right though. I had a tablist on my page and each list item had an anchor in it. I removed those and it worked.

It's OK if they have anchors.

Of course, it's good to remove them if they serve no purpose. Often, though, anchors are included in order to be read by by Javascript code. But you'd still like to prevent the default action.

That's what event.preventDefault() is for.
