I have some JS that works as follows:
If the Word Count button is pressed, go to the Word Count function, if the status of the requested page is 200, then let the url be proxyURL, which is defined correctly in index.html and this as it stands works.
I have then added an else if statement to say if a 404 is returned, then go to the function “WordCountProxyBackup” function, which works the same way as the original, but instead of using “proxyURL”, it uses proxybackupURL, which is defined in index.html
I have intentionally broken by original proxyURL to try and test this, and a 404 is returned, but the button is not finding it’s way to the backup function to then find it’s way to the backup link, can someone help with this? The code is below.
function Wordcount()
{
$(".operation").attr('disabled', true);
this.disabled = true;
let xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var j = JSON.parse(this.response);
document.getElementById('output').value = j.answer;
}else if (this.readyState == 4 && this.status == 404) {
document.getElementById('output').value = "Error Bad Pathway - Rerouting";
WordcountProxyBackup();
}
};
let url = proxyURL + "/?text=" + encodeURI(document.getElementById('content').value) + "&route=" + "wordcount";
xhttp.open("GET",url);
xhttp.send();
$(".operation").attr('disabled', false);
}
function WordcountProxyBackup()
{
$(".operation").attr('disabled', true);
this.disabled = true;
let xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var j = JSON.parse(this.response);
document.getElementById('output').value = j.answer;
}else if (this.readyState == 4 && this.status == 500) {
document.getElementById('output').value = "Error Bad Pathway - Rerouting";
WordcountProxyBackup2();
}
};
let url = proxybackupURL + "/?text=" + encodeURI(document.getElementById('content').value) + "&route=" + "wordcount";
xhttp.open("GET",url);
xhttp.send();
$(".operation").attr('disabled', false);
}
