The hashchange event fires when a window's hash changes (see location.hash).
Syntax
window.onhashchange = funcRef;
or
<body onhashchange="funcRef();">
or
window.addEventListener("hashchange", funcRef, false);
Parameters
funcRef- A reference to a function.
Example
if ("onhashchange" in window) {
alert("The browser supports the hashchange event!");
}
function locationHashChanged() {
if (location.hash === "#somecoolfeature") {
somecoolfeature();
}
}
window.onhashchange = locationHashChanged;
The hashchange event
The dispatched hashchange event has the following fields:
| Field | Type | Description |
newURL |
DOMString |
The new URL to which the window is navigating. |
oldURL |
DOMString |
The previous URL from which the window was navigated. |
Workaround for event.newURL and event.oldURL
//let this snippet run before your hashchange event binding code
if(!window.HashChangeEvent)(function(){
var lastURL=document.URL;
window.addEventListener("hashchange",function(event){
Object.defineProperty(event,"oldURL",{enumerable:true,configurable:true,value:lastURL});
Object.defineProperty(event,"newURL",{enumerable:true,configurable:true,value:document.URL});
lastURL=document.URL;
});
}());
