This is a way to determine what version of Umbraco is being used & conditionally change Angular views or logic based on that.
//Get the current umbraco version we are using when logged into the backoffice
var umbracoVersion = Umbraco.Sys.ServerVariables.application.version;
var compareOptions = {
zeroExtend: true
};
//Check what version of Umbraco we have is greater than 7.4 or not
//So we can load old or new editor UI
var versionCompare = utilityService.compareVersions(umbracoVersion, "7.4", compareOptions);
//If value is 0 then versions are an exact match
//If 1 then we are greater than 7.4.x
//If it's -1 then we are less than 7.4.x
if(versionCompare < 0) {
//I am less than 7.4 - load the legacy editor
vm.editUrl = 'edit-legacy';
}
public static bool UseLegacyEditors()
{
return UmbracoVersion.Current < new Version(7, 4);
}
var someRoutePath = Core.Configuration.UseLegacyEditors()
? "/myApp/treeAlias/edit-legacy/" + someObj.Id
: "/myApp/treeAlias/edit/" + someObj.Id;
/**
* Compares two software version numbers (e.g. "1.7.1" or "1.2b").
*
*
* @param {string} v1 The first version to be compared.
* @param {string} v2 The second version to be compared.
* @param {object} [options] Optional flags that affect comparison behavior:
* <ul>
* <li>
* <tt>lexicographical: true</tt> compares each part of the version strings lexicographically instead of
* naturally; this allows suffixes such as "b" or "dev" but will cause "1.10" to be considered smaller than
* "1.2".
* </li>
* <li>
* <tt>zeroExtend: true</tt> changes the result if one version string has less parts than the other. In
* this case the shorter string will be padded with "zero" parts instead of being considered smaller.
* </li>
* </ul>
* @returns {number|NaN}
* <ul>
* <li>0 if the versions are equal</li>
* <li>a negative integer iff v1 < v2</li>
* <li>a positive integer iff v1 > v2</li>
* <li>NaN if either version string is in the wrong format</li>
* </ul>
