Force preview
Language(s):	JavaScript
Compatible with:	MediaWiki 1.23+⁺ (Vector)

Force preview is JavaScript that prevents specified individuals or groups from saving a wiki page before they preview it at least once.

In order to use this code, insert it into your wiki's MediaWiki:Common.js page.

Note that this method is not foolproof. If a user disables JavaScript in their browser, they will not have preview forced on them. If you want to ensure that this policy is enforced, then you should look at Extension:ForcePreview .

// Force Preview and Edit-Summary - Start
if(mw.config.get("wgAction")==="edit")
$.when(mw.loader.using("user.options"),$.ready).then(function(){
var$wpSave=$("#wpSave"),
$wpPreview=$("#wpPreview"),
saveVal=$wpSave.val(),
classNames="oo-ui-widget-enabled oo-ui-flaggedElement-progressive oo-ui-flaggedElement-primary";
if(!mw.user.options.get("forceeditsummary")||mw.user.options.get("previewonfirst"))
mw.loader.using("mediawiki.api",function(){
newmw.Api().saveOptions({forceeditsummary:1,previewonfirst:0});
});
if(!$("#wikiPreview,#wikiDiff").is(":visible")&&$wpSave.length&&$wpPreview.length){
$wpSave.prop("disabled",true)
.val("Save page (use preview first)")
.parent().removeClass(classNames).addClass("oo-ui-widget-disabled");
$wpPreview.one("click",function(e){// re-enable
$wpSave.prop("disabled",false)
.val(saveVal)
.parent().removeClass("oo-ui-widget-disabled").addClass(classNames);
}).parent().addClass(classNames);
}
});
// Force Preview and Edit-Summary - End
