Every time I use Ajax to load a blog post on the webpage, I adjust the <title> to "My Blog - BLOGPOST_TITLE".
It is worth mentioning that "My Blog - " also shows up in the application layout.
My dilemma is, how do I inform my Javascript about the "My Blog - " string without repeating it in my code?
Prior to sending the Ajax request to the server, it is necessary to save the value of document.title ("My Blog") in a variable. Upon receiving the response, update the document.title by adding ' - ' followed by the BLOGPOST_TITLE.
Therefore, the HTML would show:
... < title>My Blog< /title> ...
And in the JavaScript code:
var CURRENT_TITLE = document.title;
function fetchBlogPost() {
Ajax.Request(url, {
onSuccess: function(response) {
var postTitle = extractTitle(response.responseText);
document.title = CURRENT_TITLE + " - " + postTitle;
}
})
}
If you're looking for a quick solution (not the cleanest, but effective), consider following this approach:
let blogTitlePrefix = 'My Amazing Blog - '
Then simply adjust the title by combining the prefix with the title of the blog post like so:
document.title = blogTitlePrefix + postTitle
