In previous tips I introduced a basic HTML Drag and Drop API example along with some things you can do with the dataTransfer() object. This tip will focus on the different events you can listen for during a drag operation.

There are 7 drag events that are supported across all modern browsers. They are:

dragstart - A dragging operation begins (on dragged item)
drag - A drag operation is in process (on dragged item)
dragenter - A dragged item enters a valid drop target (on drop target)
dragover - A valid drop target is dragged over (on drop target)
dragleave - A dragged item leaves a valid drop target (on drop target)
drop - A dragged item is dropped on a valid drop target (on drop target)
dragend - A drag operation ends (on dragged item)

The notes in parentheses next to each bullet point indicate where the event listener would be placed when listening for the event.

As usual, this is always more interesting with an interactive example, so here's a CodePen demo that illustrates all 7 drag events by printing each one on the page as the event occurs. Some events, of course, occur simultaneously. Also, in order to see the dragleave event, you have to 'leave' the drop target before entering it again to complete the drop.

The demo displays each message once but it should be noted that the drag and dragover events fire continuously while the item is dragged or while the drop target is being dragged over. The rest of the events occur one time each then won't occur again until another drag operation is initiated, ended, or another drop target is accessed, etc.

It should also be noted that MDN's article that lists the different events also lists a dragexit event that has some browser support. But it's recommended to use the dragleave event (which is apparently the equivalent) instead.

Now on to this week's tools!

If you're a big Seinfeld fan like I am, you'll love this: Seinfeld Adventure. Right now it's just a pitch for a game. I seriously doubt Jerry and his producers will approve this, but it's pretty cool to see what it would be like to play "a game about nothing".

Report: ‘Tremendous Progress’ Ahead for Religious Freedom Worldwide

By feeds.christianitytoday.com
Published On :: Tue, 28 Apr 2020 15:35:00 GMT

USCIRF chair Tony Perkins gives CT a behind-the-scenes look at today’s annual report on “systematic, ongoing, and egregious” violations.

A new report aims to “unflinchingly criticize the records of US allies and adversaries alike” on religious freedom.

And there’s a lot to report, with more headlines each month confirming the Pew Research Center’s 10-year analysis that government restrictions and social hostilities involving religion have reached record levels worldwide.

Today’s 21st annual report by the US Commission on International Religious Freedom (USCIRF) identifies significant problems in 29 countries—but sees “an upward trajectory overall.”

“Our awareness is going to grow greater, and the problem will appear more pronounced,” USCIRF chair Tony Perkins told CT. “But as we continue to work on it, I think we will see tremendous progress in the next few years if we stay the present course.”

Created as an independent, bipartisan federal commission by the 1998 International Religious Freedom Act, USCIRF casts a wider net than the US State Department, which annually designates Countries of Particular Concern (CPC) for such nations’ violations of religious freedom, or places them on a Special Watch List (SWL) if less severe.

Last December, Secretary of State Mike Pompeo announced CPC status for Burma, China, Eritrea, Iran, North Korea, Pakistan, Saudi Arabia, Tajikistan, and Turkmenistan.

USCIRF now recommends adding India, Nigeria, Russia, Syria, and Vietnam.

And where the State Department put only Cuba, Nicaragua, Sudan, and Uzbekistan on the watch list, USCIRF recommends also including Afghanistan, Algeria, Azerbaijan, Bahrain, Central African Republic, Egypt, Indonesia, Iraq, Kazakhstan, Malaysia, and Turkey.

USCIRF’s mandate is to provide oversight and advice to the State Department. ...

Why We Opened a Christian University in Iraq Amid ISIS’ Genocide

By feeds.christianitytoday.com
Published On :: Thu, 07 May 2020 01:21:00 GMT

CT interviews Stephen Rasche on Erbil’s Catholic presence, the need for Christian unity, and why Christians will “no longer be shy” with the gospel.

For 25 years, Stephen Rasche was a “bare knuckles” international lawyer. But in 2010, he offered his services to the Chaldean Catholic Church of Erbil in Iraqi Kurdistan and has increasingly dedicated his life to the preservation of this ancient community.

Under the leadership of Archbishop Bashar Matti Warda, in 2015 Rasche helped found the Catholic University of Erbil, where he serves as vice chancellor. Also the director of its Institute for Ancient and Threatened Christianity, Rasche lived this title as ISIS ravaged Iraq’s Christian homelands in the Nineveh Plains and many believers fled to Erbil.

After testifying on their behalf before the United Nations and the US Congress, Rasche allows them to represent themselves in his recent book, The Disappearing People: The Tragic Fate of Christians in the Middle East. The book has won a diverse range of endorsements, from leaders such as Matthew Hassan Kukah, bishop of the Catholic Diocese of Sokoto, Nigeria; Yahya Cholil Staquf, general secretary of Nahdlatul Ulama, the largest Muslim organization in the world; and Thomas Farr, president of the Religious Freedom Institute.

The US State Department’s Office of International Religious Freedom reports that less than 250,000 Christians are living in Iraq, most in Kurdistan or on the Nineveh Plains. Two-thirds belong to the Chaldean Catholic Church.

CT interviewed Rasche about the logic of establishing a university during a genocide, how its Catholic identity functions in a Muslim society, and his enduring optimism for Christianity in Iraq.

What led you personally to invest your life in this endeavor?

In 2010, Bishop Warda had just been made archbishop, and I went to pay him a visit of respect, asking if there ...
