kendo ui autocomplete - json file datasource - template - 404 Not Found error - /undefined URL

Below code has been thankfully provided by machun for toggling between RTL and LTR directions in Kendo UI widgets.

The code consists of:

HTML: kendo autocomplete form plus a button to activate support for RTL and LTR language.

Script:

  • k-rtl class container
  • datasource (json file)
  • kendo autocomplete widget initializing + template to show image beside data and to open data links in the same tab
  • k-rtl class

The problem is that links don't open correctly. It shows a 404 Not Found error plus a /undefined at the end of the URL.

Solution

  • I advice to debug your function first then simply check the variable and make sure it contain the right thing. You overlooked a simple thing that your jquery dom selector isn't quite right resulting var href contain "undefined".

    Change

     var href = e.item.find("span").data("href");

    To

    var href = e.item.find("span[data-href]").attr("data-href");
