I have a javascript which parse the server data and stores it in a variable. I can use that variable only in one function but not in multiple functions, please find the javascript code below.
function serverData(command, param) {
console.log('command is ' + command + ' param is ' + param);
if (!command) {
console.log('Command not recieved, No call to Server');
return;
}
var url = 'ProgramSetting.cgi?command=' + command;
if (param) {
url += '&' + param;
}
var xhttp = new XMLHttpRequest();
xhttp.open('GET', url, true);
xhttp.setRequestHeader('Content-Type', 'application/json');
xhttp.send();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var data = JSON.parse(this.responseText);
responseHandler(command, data);
}
};
}
function responseHandler(command, jsonData) {
if (!jsonData) {
console.log('Json from server not defined!!!');
return;
}
switch (command) {
case 'set':
if (jsonData.result == 'success') {
document.getElementById('info').innerHTML = 'INFO: Committed successfully!';
} else {
if (jsonData.options && jsonData.options.length > 0) {
var failedOptions = '';
for (var i = 0; i < jsonData.options.length; i++) {
failedOptions += ' ' + jsonData.options[i];
}
document.getElementById('info').innerHTML =
'ERROR: Failed to commit following option(s)-' + failedOptions;
} else {
console.log('Failed to Commit');
document.getElementById('info').innerHTML = 'ERROR: Failed to Commit';
}
initialPageLoad();
document.getElementById('info').style.color = 'red';
}
break;
case 'get':
console.log('jsonData.POLICY is ' + jsonData.POLICY);
if (jsonData.POLICY == 'gehc') {
document.getElementById('list1').checked = true;
gehc();
} else if (jsonData.POLICY == 'strict') {
document.getElementById('list2').checked = true;
strictgehc();
} else if (jsonData.POLICY == 'custom') {
document.getElementById('list3').checked = true;
custom(jsonData);
}
break;
default:
console.log("we don't support this");
}
}
function custom(jsonData) {
console.log('Custom called');
console.log('jsonData.MINLEN_RANGE is ' + jsonData.MINLEN_RANGE);
document.getElementById('Minlen_text').value = jsonData.MINLEN_RANGE;
document.getElementById('Minlen_text').disabled = false;
console.log('jsonData.EXPIRY is ' + jsonData.EXPIRY);
document.getElementById('Expiry_text').value = jsonData.EXPIRY;
document.getElementById('Expiry_text').disabled = false;
document.getElementById('reset').disabled = false;
}
function initialPageLoad() {
console.log('Retrieving data from Server calling get');
serverData('get');
}
In the above script I am able to use jsonData in responseHandler() function but cannot use in``custom()` function.

i am new to laravel 8 and ajax and also i am working in a group.
I have a blade view to view the data of a user and since from this view I would like to make it possible to modify some data without a form tag I have made a js script to send the new data to be modified to a method of a controller but this data does not never arrive at the controller as I notice that the mysql db and the profilo view is not updated, however some "debug" printouts report a success.
Where am I wrong? Thanks in advance.
This is the controller

A FormData object is sent with content-type multipart/form-data not application/x-www-form-urlencoded. In your code remove the line where you set the content-type header, the correct content-type header will be set automatically.
in my chat extension for phpBB, i use ajax for the js with a little jquery mixed in. i'm setting it up for users to select if they want the newest messages at the top or the bottom in accordance to their setting in their user control panel. the php side of it is done and works well but the js is still adding the new message at the top, ignoring the sort order in the php.
in the php. note that the sort order is set with this line
ORDER BY c.message_id ' . ($this->user->data['user_ajax_chat_messages_down'] ? 'DESC' : 'ASC');
i can't post the php in this post as the body is limited to 30000 characters. so i will post it if needed.
here is the js that does all the work

what needs to be changed to accomplish what i'm trying to do? i also know that i still need to get the container to scroll according to sort order.
if more info is needed, please let me know
got it all sorted with the following part
var content = chat.innerHTML;
chat.innerHTML = isDown ? (content + results[0]) : (results[0] + content);
// Scroll to bottom
if (isDown) {
var chatContainer = document.querySelector('.shout-body');
chatContainer.scrollTop = chatContainer.scrollHeight;
}```
I have created an app where I am recording an audio in wav format and then replaying that audio and then posting it to api for further processing.
But after posting data to api it says "not a wave file -- no riff header".
I tried this link also as reference.
Here is my javascript code of app:
var mediaVar = null;
var recordFileName = "recording.wav";
var mediaVarSrc = "cdvfile://localhost/sdcard/recording.wav";
var status = null;
var target = "";
document.getElementById("start-btn").addEventListener("click", function () {
createMedia(function () {
status = "recording";
mediaVar.startRecord();
}, onStatusChange);
$("#recordingText").show();
});
document.getElementById("stop-btn").addEventListener("click", function () {
stop();
});
function createMedia(onMediaCreated, mediaStatusCallback) {
if (mediaVar != null) {
onMediaCreated();
return;
}
if (typeof mediaStatusCallback == 'undefined') {
mediaStatusCallback = null;
}
window.resolveLocalFileSystemURL(cordova.file.externalRootDirectory, function (fileSystem) {
fileSystem.getFile(recordFileName, {
create: true,
exclusive: false
}, function (fileEntry) {
fileUrl = fileEntry.toURL();
mediaVar = new Media(fileUrl,
function () {}, onError, mediaStatusCallback);
onMediaCreated();
}, onError);
}, onError);
}
function stop() {
alert("Stop");
$("#recordingText").hide();
if (mediaVar == null) {
return;
}
if (status == 'recording') {
mediaVar.stopRecord();
mediaVar.release();
status = 'stopped';
play();
} else {
alert("Nothing stopped");
}
}
function play() {
if (mediaVar) {
status = "playing";
//playAudioFile(recordFileName);
window.resolveLocalFileSystemURL(cordova.file.externalRootDirectory + recordFileName, function (tempFile) {
alert(JSON.stringify(tempFile));
tempFile.file(function (tempWav) {
alert(JSON.stringify(tempWav));
var options = new FileUploadOptions();
options.chunkedMode = false;
options.fileKey = "file";
options.fileName = recordFileName;
options.mimeType = "audio/wav";
var ft = new FileTransfer();
ft.upload(tempFile.nativeURL, encodeURI(target), function () {
alert("Win");
}, function () {
alert("false");
}, options, true);
});
}, function (e) {
console.log("Could not resolveLocalFileSystemURL: " + e.message);
});
}
}
var myMedia = null;
function playAudioFile(src) {
myMedia = new Media(src,
function () { },
function (error) { },
function (status) { }
);
myMedia.play();
}
function stopplay(calledfrom) {
mediaVar.stop();
}
function recordAudio() {
if (myMedia == null) {
myMedia = new Media(srcurl,
function () {
console.log("recordAudio():Audio Success");
},
function (err) {
console.log("recordAudio():Audio Error: " + err.code);
});
}
myMedia.startRecord();
}
For recording I have used Media plugin. I am not able to figure out why this is happening.

I have a Function named "ViewItem" that calls 2 more functions: "success" and "failed". When "success" is called it goes and check if a value exists and return true if the value exists or false if the value doesnt exist. Lastly I have a 4th function called "PresaveAction" what this function does is check if a value is "yes" or "no", if "no" it returns true and allows me to save and what I want to achieve is if the value is "yes" call the "success" function from before and depending if "success" returns true or false allow me to save. So how do I pass to the PreSaveAction function what "success" return?
function ViewItem()
{
var context = new SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('demoTrainingRoom2');
var query = SP.CamlQuery.createAllItemsQuery();
allItems = list.getItems(query);
context.load(allItems, 'Include(Title, EventDate, time2)');
context.executeQueryAsync(Function.createDelegate(this, this.success), Function.createDelegate(this, this.failed));
}
function success() {
var currentTitle = SPUtility.GetSPFieldByInternalName('EventDate').GetValue();
for(var i = 0; i < this.allItems.get_count(); i++){
var item = this.allItems.get_item(i);
console.log(item.get_item('time2') + ' - ' + currentTitle );
if (currentTitle == item.get_item('time2')){
alert('There is an event with the same Start Date on DemoTrainingRoom2' + ' ' + item.get_item('time2') + ' - ' + currentTitle );
return true; // or item
}
}
return false;
}
function failed(sender, args) {
alert("failed. Message:" + args.get_message());
}
function PreSaveAction() {
var time = SPUtility.GetSPFieldByInternalName('EventDate').GetValue();
alert(time + " Current Start Time");
if(SPUtility.GetSPField('demoField').GetValue() == "no")
{
alert('No need for validation');
return true; // save file
}
else
{
alert('Need to validate date');
//here is where i need to call the result from success
return false; // don't save file

This is how i did it

}
$(saveButton).attr("onclick", "PreSaveAction2()"); //change });
});
//override the default PreSaveAction
//custom PreSaveAction

alert("iniciando validacion");

I need to send request to server in sync mode, so i set async=false, but i receive always NETWORK_ERR: XMLHttpRequest Exception 101. Here is my code, there i someone that know how can i improve it to fix this issue?
var request = new XMLHttpRequest();
request.open("GET", 'ip-address ', false);
request.onreadystatechange = function () {
if (request.readyState == 4) {
if (request.status == 200 || request.status == 0) {
var data = JSON.parse(request.responseText);
var object = "";
var string = "";
var find = false;
window.localStorage.setItem(data.id, JSON.stringify(data));
$.each(data.img, function (i, item) {
if (data.img[i].principal) {
string = data.img[i].path;
}
});
if (string == "") string = data.img[0].path;
var splitt = string.substring(2);
window.localStorage.setItem("img" + data.id, splitt);
if ($("#img" + (l + 1)).attr("src") === 'ip-address' + splitt) {
find = true;
} else {
object='<img id="img'+(l+1)+'" src="ip-address'+splitt+'" name="'+data.id+'"></img>'; if (!trovata) {
if (flag) {
$("#" + (l + 1)).empty();
$("#" + (l + 1)).html(object);
if (l == 0) {
$("#" + (l + 1)).flip({
direction: 'tb'
});
} else {
switch (l % 2) {
case (1):
$("#" + (l + 1)).flip({
direction: 'lr'
});
break;
case (0):
$("# " + (l + 1)).flip({
direction: 'rl'
});
break;
}
}
}
}
}
}
}
request.send();
