Eine andere Möglichkeit, die Anzeige nach dem Hash zu handhaben (wenn Sie also pushState nicht verwenden!), Besteht darin, Ihren CustomLocation zu erstellen und ihn bei der ReactRouter-Erstellung zu laden.
Wenn Sie beispielsweise eine Hashbang-URL (also mit #!) Haben möchten, um den Google-Spezifikationen für das Crawlen zu entsprechen, können Sie eine HashbangLocation.js-Datei erstellen, die hauptsächlich die ursprüngliche HashLocation kopiert, z.
'use strict';
var LocationActions = require('../../node_modules/react-router/lib/actions/LocationActions');
var History = require('../../node_modules/react-router/lib/History');
var _listeners = [];
var _isListening = false;
var _actionType;
function notifyChange(type) {
if (type === LocationActions.PUSH) History.length += 1;
var change = {
path: HashbangLocation.getCurrentPath(),
type: type
};
_listeners.forEach(function (listener) {
listener.call(HashbangLocation, change);
});
}
function slashToHashbang(path) {
return "!" + path.replace(/^\//, '');
}
function ensureSlash() {
var path = HashbangLocation.getCurrentPath();
if (path.charAt(0) === '/') {
return true;
}HashbangLocation.replace('/' + path);
return false;
}
function onHashChange() {
if (ensureSlash()) {
// If we don't have an _actionType then all we know is the hash
// changed. It was probably caused by the user clicking the Back
// button, but may have also been the Forward button or manual
// manipulation. So just guess 'pop'.
var curActionType = _actionType;
_actionType = null;
notifyChange(curActionType || LocationActions.POP);
}
}
/**
* A Location that uses `window.location.hash`.
*/
var HashbangLocation = {
addChangeListener: function addChangeListener(listener) {
_listeners.push(listener);
// Do this BEFORE listening for hashchange.
ensureSlash();
if (!_isListening) {
if (window.addEventListener) {
window.addEventListener('hashchange', onHashChange, false);
} else {
window.attachEvent('onhashchange', onHashChange);
}
_isListening = true;
}
},
removeChangeListener: function removeChangeListener(listener) {
_listeners = _listeners.filter(function (l) {
return l !== listener;
});
if (_listeners.length === 0) {
if (window.removeEventListener) {
window.removeEventListener('hashchange', onHashChange, false);
} else {
window.removeEvent('onhashchange', onHashChange);
}
_isListening = false;
}
},
push: function push(path) {
_actionType = LocationActions.PUSH;
window.location.hash = slashToHashbang(path);
},
replace: function replace(path) {
_actionType = LocationActions.REPLACE;
window.location.replace(window.location.pathname + window.location.search + '#' + slashToHashbang(path));
},
pop: function pop() {
_actionType = LocationActions.POP;
History.back();
},
getCurrentPath: function getCurrentPath() {
return decodeURI(
// We can't use window.location.hash here because it's not
// consistent across browsers - Firefox will pre-decode it!
"/" + (window.location.href.split('#!')[1] || ''));
},
toString: function toString() {
return '<HashbangLocation>';
}
};
module.exports = HashbangLocation;
Beachten Sie die Funktion slashToHashbang .
Dann musst du es tun
ReactRouter.create({location: HashbangLocation})
Und das ist es :-)
