i need following function to be execute in Firefox.., but it is working fine in chrome. the problem was when i do 'Inspect Element With Firebug' it is working fine. the method 'EditEncounterBillStatus' is also hitting correctly. but when i don't use 'Inspect Element With Firebug' the method EditEncounterBillStatus is not hitting.. i tried a lot to sort out this. but still i can't can any one help me to find solution thanks in advance.
else if (element.trim() == "Approved") {
var TestPin = prompt("Please Enter your PIN");
if (TestPin != null) {
if (isNaN(TestPin)) {
alert("Please Enter a Valid Pin");
return;
}
else if (TestPin == pin) {
var postVisitData = { VisitId: vid};
$.post("/Emr/WaitingRoom/EditEncounterBillStatus", { VisitId: vid }, function (data) {
});
window.location = "/Emr/Patients/Show?PID=" + pid;
}
else {
alert("Your Entered PIN Is Incorrect");
}
}
else {
return;
}
}
I would recommend doing it like this
else if (TestPin == pin) {
$.post("/Emr/WaitingRoom/EditEncounterBillStatus", { VisitId: vid }, function (data) {
window.location = "/Emr/Patients/Show?PID=" + pid;
});
return; // in case of side effects in unseen code
}
i.e. wait until the $.post has finished before changing the window.location
As the rest of your code is unseen there could be side effects of performing this in this way - hence the return where it is - but even then, not knowing the full call stack there could still be side effects - you have been warned
You should change location upon the success of the post call, so put that in your callback function body:
$.post("/Emr/WaitingRoom/EditEncounterBillStatus", { VisitId: vid },
function (data) {
window.location = "/Emr/Patients/Show?PID=" + pid;
});
This way you are sure you only change location when the post action was executed. Otherwise you risk that you change location before the post happens. In debug mode, and certainly when you step through the code, there is enough time for the post to finish in time, and so your original code then works.

I have the following code. There is a button in the UI that when clicked executes the if statement. I pass in a URL from a database and compare it to the current URL the user is on. If they match I want to run the code below, else I want to open the correct tab then run the code below.
With this code below I mean everything below starting from $('#sceanrioDropdownList').change(function () {...}. The code then checks a drop down and gets the selected Id from which an AJAX call is made to my web API that uses that Id in a stored procedure to return the results. The returned data is then iterated over and stored in variables which I am using to append to specific inputs, buttons and drop downs.
This is what I have so far and I think I have developed this correctly. The issue that I am currently having is that the UI wants everything from ... to be run if the if statement is true. I have tried CTRL+C and CTRL+V to copy the code into the if statement. I have also tried putting it in a new function and referencing that function n the if statement. Both do not work and I was using console.log to inspect the returned data.
It does however when I attempt to call it from inside i statement it doesn't return any data or error. It just doesn't seem to fire.
Is there a way in which I can achieve the functionality I desire? Do you have any suggestions as to if I have done something wrong. Thanks in advance.
$('#automate').click(automateButton);
function automateButton() {
if (webpageUrl == activeTabUrl) {
// do nothing
} else {
// Window opens
window.open(webpageUrl);
}
}
$('#scenarioDropdownList').change(function() {
var scenarioId = $('#scenarioDropdownList option:selected').prop('id');
getData(scenarioId);
});
function getData(scenarioId) {
$.ajax({
type: "GET",
url: 'http://localhost:54442/api/scenariodatas/GetScenarioData',
data: {
scenarioId: scenarioId
},
dataType: 'JSON',
success: scenarioData,
error: function() {
console.log("There has been an error retrieving the data");
}
});
}
function scenarioData(response) {
$.each(response, function(key, val) {
var fieldType = val.fieldType;
var fieldName = val.fieldName;
var fieldValue = val.fieldValue;
var field = $(fieldName);
if (field != undefined) {
switch (fieldType) {
case "Input":
$(field).val(fieldValue);
break;
case "Button":
$(field).click();
break;
case "Select":
$(field).val(fieldValue);
break;
}
}
})
}
onChange don´t work well with buttons because onChange detect a change in the value of your component, because of this, it´s highly recommended to use onClick when you use a button.
$('#scenarioDropdownList').click(function() {
var scenarioId = $('#scenarioDropdownList option:selected').prop('id');
getData(scenarioId);
});
I recommend you to put alerts when you are trying to test this sort of JS
EJM:
$('#scenarioDropdownList').change(function() {
alert('button active');
var scenarioId = $('#scenarioDropdownList option:selected').prop('id');
getData(scenarioId);
});
this alert allow you to know if the code is firing or not
I am detecting the end of a webrtc stream in JavaScript like this...
stream.getVideoTracks()[0].onended = () => {
alert('Feed Has Ended');
};
This is working correctly, but if the user refreshes or reloads the page then the alert is also shown.
I understand that this is technically correct, but how can I get it to not display the alert under those conditions?
Why don't you use a global boolean to check if video is playing or not? When you will reload or refresh the page, isVideoRunning will become false and alert won't show.
Like
this.isVideoRunning = false;
On addtrack,
this.rtcPeerCon_.ontrack = function (event) {
if (!this.rtcPeerCon_) {
return;
}
if( !this.remoteVideo_ ) {
return;
}
this.remoteVideo_.srcObject = event.streams[0];
this.isVideoRunning = true;
}
then in your onStream ended callback you can check
if (this.isVideoRunning) {
alert('whatever');
this.isVideoRunning = false;
}

Here's the problem. I'm making a callback to the server that receives an MVC partial page. It's been working great, it calls the success function and all that. However, I'm calling a function after which iterates through specific elements:
$(".tool-fields.in div.collapse, .common-fields div.collapse").each(...)
Inside this, I'm checking for a specific attribute (custom one using data-) which is also working great; however; the iterator never finishes. No error messages are given, the program doesn't hold up. It just quits.
Here's the function with the iterator
function HideShow() {
$(".tool-fields.in div.collapse, .common-fields div.collapse").each(function () {
if (IsDataYesNoHide(this)) {
$(this).collapse("show");
}
else
$(this).collapse("hide");
});
alert("test");
}
Here's the function called in that, "IsDataYesNoHide":
function IsDataYesNoHide(element) {
var $element = $(element);
var datayesnohide = $element.attr("data-yes-no-hide");
if (datayesnohide !== undefined) {
var array = datayesnohide.split(";");
var returnAnswer = true;
for (var i in array) {
var answer = array[i].split("=")[1];
returnAnswer = returnAnswer && (answer.toLowerCase() === "true");
}
return returnAnswer;
}
else {
return false;
}
}
This is the way the attribute appears
data-yes-no-hide="pKanban_Val=true;pTwoBoxSystem_Val=true;"
EDIT: Per request, here is the jquery $.post
$.post(path + conPath + '/GrabDetails', $.param({ data: dataArr }, true), function (data) {
ToggleLoader(false); //Page load finished so the spinner should stop
if (data !== "") { //if we got anything back of if there wasn't a ghost record
$container.find(".container").first().append(data); //add the content
var $changes = $("#Changes"); //grab the changes
var $details = $("#details"); //grab the current
SplitPage($container, $details, $changes); //Just CSS changes
MoveApproveReject($changes); //Moves buttons to the left of the screen
MarkAsDifferent($changes, $details) //Adds the data- attribute and colors differences
}
else {
$(".Details .modal-content").removeClass("extra-wide"); //Normal page
$(".Details input[type=radio]").each(function () {
CheckOptionalFields(this);
});
}
HideShow(); //Hide or show fields by business logic
});
For a while, I thought the jquery collapse was breaking, but putting the simple alert('test') showed me what was happening. It just was never finishing.
Are there specific lengths of time a callback function can be called from a jquery postback? I'm loading everything in modal views which would indicate "oh maybe jquery is included twice", but I've already had that problem for other things and have made sure that it only ever includes once. As in the include is only once in the entire app and the layout is only applied to the main page.
I'm open to any possibilities.
Thanks!

Found the problem. I had a variable that was sometimes being set as undefined cause it to silently crash. I have no idea why there was no error message.
I have a series of buttons that execute different functions when clicked. The function checks whether the user is logged in, and if so proceeds, if not it displays an overlay with ability to log in/create account.
What I want to do is re-execute the button click after log-in, without the user having to reclick it.
I have it working at the moment, but I'm pretty sure that what I'm doing isn't best practice, so looking for advice on how I can improve...
Here's what I'm doing: setting a global variable "pending_request" that stores the function to be re-run and in the success part of the log-in ajax request calling "eval(pending_request)"
Example of one of the buttons:
jQuery('#maybe_button').click(function() {
pending_request = "jQuery('#maybe_button').click()"
var loggedin = get_login_status();
if (loggedin == true) {
rec_status("maybe");
}
});
.
success: function(data) {
if(data === "User not found"){
alert("Email or Password incorrect, please try again");
}else{
document.getElementById('loginscreen').style.display = 'none';
document.getElementById('locationover').style.display = 'none';
eval(pending_request);
pending_request = "";
}
}
Register a function to handle the click and then invoke that func directly without eval().
jQuery('#maybe_button').on('click', myFunction)
This executes myFunction when the button is clicked. Now you can "re-run" the function code every time you need it with myFunction().
And btw since you are using jQuery you can do $('#loginscreen').hide() where $ is an alias for jQuery that's auto defined.
EDIT
Please, take a look at the following code:
var pressedButton = null;
$('button1').on('click', function() {
if (!isLoggedIn()) {
pressedButton = $(this);
return;
}
// ...
});
And, in your success handler:
success: function() {
// ...
if (pressedButton) pressedButton.trigger('click');
// ...
}
I'm using the bit.ly url shortening service to shorten certain url's being sent to a "share on twitter" function. I'd like to load the bit.ly url only when a user actually presses the share button (due to bit.ly's max 5 parallel reqs limitation). Bit.ly's REST API returns a JSON callback with the shortened url, which makes the whole scenario async.
I've tried the following to stop the click event, and wait for the JSON call to return a value before launching the click.
I have the following simplified code in jQuery(document).ready():
Updated code (oversimplified)!
jQuery("#idofaelement").click(function(event) {
event.preventDefault(); //stop the click action
var link = jQuery(this);
bitlyJSON(function(shortUrl) {
link.attr("href", function() {
//process shortUrl
//return finalized url;
}).unbind().click();
});
});
And the following code to handle the bitly shortening (works just fine):
function bitlyJSON(func) {
//
// build apiUrl here
//
jQuery.getJSON(apiUrl, function(data) {
jQuery.each(data, function(i, entry) {
if (i == "errorCode") {
if (entry != "0") {
func(longUrl);}
} else if (i == "results") {
func(entry[longUrl].shortUrl);}
});
});
} (jQuery)
The href gets its value changed, but the final .click() event never gets fired. This works fine when defining a static value for the href, but not when using the async JSON method.
As you outlined yourself:
event.preventDefault(); //stop the click action
That means, BROWSER IS NOT GOING TO THAT URL, if you wish to actually go forward to the long-url location, simply do something like:
document.location.href = longurl;
iirc, jquery doesn't trigger "click" on A elements. I'd try old good "location.href=whatever" in the callback.
bitlyJSON(function(shortUrl) {
link.attr("href", function() {
//process shortUrl
//return finalized url;
});
location.href = link.attr("href");
});
I think what you actually want is to return false; from the click event, to prevent the actual following of the href, right?
Like:
jQuery("#idofaelement").click(function(event) {
//event.preventDefault(); //stop the click action
var link = jQuery(this);
bitlyJSON(function(shortUrl) {
link.attr("href", function() {
//process shortUrl
//return finalized url;
}).unbind().click();
});
return false;
});
#Tzury Bar Yochay pointed me in the right direction by suggesting I use location.href to update the url. Also #Victor helped with his answer.
I got things kinda working combining the answers, but had issues with the history in firefox. Seems that updating window.location indeed redirected the user, but also removed the "source page" from the history. This did not happen in chrome, safari, ie8, ie8-compatibility or ie7.
Based on this response to another question I was able to create a workaround giving the following working code + made a few changes:
jQuery("#idofaelement").one("click", function(event) {
bitlyJSON(function(shortUrl) {
jQuery("#idofaelement").attr("href", function() {
//process shortUrl
//return finalized url;
});
setTimeout(function() {
window.location = jQuery("#idofaelement").attr("href");
}, 0);
});
return false;
});
Thanks for all the help!
