Description
In one of my extensions I use internal method htmx.swap(). I also use head support extension as well. head-support extension has below code where it tap into htmx:afterSwap. It try to access the evt.detail.xhr and it's null in my case because I used htmx.swap() inside my extension.. I think we should execute head-support only if it has a valid xhr responce. a simple null check would do?
htmx.defineExtension("head-support", {
init: function(apiRef) {
// store a reference to the internal API.
api = apiRef;
htmx.on('htmx:afterSwap', function(evt){
var serverResponse = evt.detail.xhr.response;
if (api.triggerEvent(document.body, "htmx:beforeHeadMerge", evt.detail)) {
mergeHead(serverResponse, evt.detail.boosted ? "merge" : "append");
}
})
htmx.on('htmx:historyRestore', function(evt){
if (api.triggerEvent(document.body, "htmx:beforeHeadMerge", evt.detail)) {
if (evt.detail.cacheMiss) {
mergeHead(evt.detail.serverResponse, "merge");
} else {
mergeHead(evt.detail.item.head, "merge");
}
}
})
htmx.on('htmx:historyItemCreated', function(evt){
var historyItem = evt.detail.item;
historyItem.head = document.head.outerHTML;
})
}
});
