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 = $wpSave.val(), classNames = "oo-ui-widget-enabled oo-ui-flaggedElement-progressive oo-ui-flaggedElement-primary"; if (!mw.user.options.get("forceeditsummary") || mw.user.options.get("previewonfirst")) mw.loader.using("mediawiki.api", function () { new mw.Api().saveOptions({forceeditsummary: 1, previewonfirst: 0}); }); if (!$("#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
