I'm trying to open the Enrichr website (https://amp.pharm.mssm.edu/Enrichr/) and auto-fill a list of genes into the large box for genes. Here the variable "data" represents those genes. I have a button in my html code that executes the following function:
function myFunction()
{
var data = "hello";
var OpenWindow =window.open("https://amp.pharm.mssm.edu/Enrichr/");
OpenWindow.onload = function(){
OpenWindow.document.getElementById("text-area").value = data;
}}
This code doesn't seem to work. It opens the webpage but does not fill anything out. I don't think the onload function is working properly.
I think the problem is that you want to change OpenWindow.document.getElementById("text-area").value before page load completly. Maybe try it like this:
function myFunction() {
var data = "hello";
var OpenWindow =window.open("https://amp.pharm.mssm.edu/Enrichr/");
OpenWindow.onload = function () {
OpenWindow.document.getElementById("text-area").value = data;
}
}

I have a page that will open a popup and after something is done on that popup and user close it I want to get data from table / tds. Here is my calling function:
function clicked() {
windowOpener("SiteMap.html");
popupWin.onbeforeunload = function () {
var a = $("#drawTable", popupWin.document);
var tds = $(a).find("td");
tds.each(function () {
var p = $(this).data('point');
if (JSON.stringify(p.values) !== JSON.stringify(point.values)) { //here comes error, to this line
console.log(p.values);
}
})
};
}
.data('point') is created and populated already on that popup page, but still I am getting that $(this).data('point') is undefined. So, is it possible that in that point data is already destroyed? What is your recommendation how to deal with this?
thanks
This is probably such a noob question, but I can't get it to work.
I want to open external window link by clicking on anchor tag, but I keep getting error that myFunction() is not defined.
Open link
js
$(document).ready(function() {
$('#searchEng').click(function() {
const engine = document.getElementById('engine');
var en_ = engine.val();
if (en_ == "firefox")
{
function myFunction() {
var url = "https://www.mozilla.org/en-US/firefox/new/";
window.open(url,'_blank');
};
}
});
));
Why is it undefined?
I have .js included because other stuff works.
you can remove function inside click function
$(document).ready(function(){
$('#searchEng').click(function() {
const engine = document.getElementById('engine');
var en_ = engine.val();
if (en_ == "firefox")
{
var url = "https://www.mozilla.org/en-US/firefox/new/";
window.open(url,'_blank');
}
});

You declared myFunction inside another function, which makes it a local variable of that function. Local variables aren't available outside the function where they were defined.
I have a user script that does some stuff after clicking a button. By clicking the same button again (like a toggle button), I want it to 'revert' back to default. By default I mean the on page load content. Check my code:
var myTbl = document.getElementsByClassName("myTable")[0];
var myCells = myTbl.getElementsByTagName("td");
myCells[2].innerHTML = "<span id='myButton' class='button'>Do something / Revert</span>";
document.getElementById("myButton").addEventListener("click", doSomething, false);
function doSomething() {
// do some stuff with myTbl
document.getElementById("myButton").removeEventListener("click", doSomething, false);
document.getElementById("myButton").addEventListener("click", revertToDefault, false);
}
function revertToDefault() {
// location.reaload();
}
I could do it with location.reaload();, but that's not what I want. I would prefer to save the default on load content in a variable like I did with the variable myTbl var myTbl = document.getElementsByClassName("myTable")[0]; and preserve that default content and then simply save that default content in the variable myTbl myTbl = defaultTbl; when executing the revertToDefault() function. What's the correct code to do that? Is there a better way of doing that, perhaps without the need of saving everything in a variable?
A possible working solution:
var myTbl = document.getElementsByClassName("myTable")[0];
var defaultTbl = myTbl.innerHTML; // this way defaultTbl remains intact while manipulating myTbl object
function revertToDefault() {
myTbl.innerHTML = defaultTbl;
}
I'm trying to update contents of a chat located in div (div1) but only when the contents of div1 change (a message was submitted into db and picked up in div1).
I tried the solution from here but my get fails to compare the data.
This solution works perfectly but without content comparison:
window.onload = startInterval;
function startInterval()
{
setInterval("startTime();",2000);
}
function startTime()
{
jQuery('#div1').load('index.php #div1 > *');
}
This is the modification based on this, which fails:
window.onload = startInterval;
function startInterval()
{
setInterval("startTime();",2000);
}
function startTime()
{
var $main = $('#div1');
$.get('chat.php #div1', function (data)
{
if ($main.html() !== data) $main.html(data);
});
}
I tried various modifications of this code but to no avail...
I can't reload the entire page and I don't want to do this if not necessary since it makes the chat harder to read if you have to scroll trough the messages.
How can this be fixed?
UPDATE
Based on #T.J's suggestions I modified the code which now works perfectly:
window.onload = startInterval;
function startInterval()
{
setInterval(startTime,3000);
scrolDown();
}
function startTime()
{
var $main = $('#div1');
$.get('#div1', function (data)
{
elements = $(data);
thisHTML = elements.find("#div1").html();
if ($main.html() !== thisHTML) {
$main.html(thisHTML);
scrolDown();
}
});
}
The other problem was that get required library:
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.pack.js"></script>
which apparently was not required by the load which I used previously.
You want to use get, but you want the fragment feature of load, so you'll have to do that work yourself. Then remember what you got last time, and only update if it's not the same:
var lastHTML;
function startTime()
{
var $main = $('#div1');
$.get('chat.php', function (data) // <== Or index.php, the question has both
{
var elements, html;
// Turn the HTML into elements
elements = $(data);
// Get the HTML of *only* the contents of #div1
html = elements.find("#div1").html();
// If that has changed, use it
if (lastHTML !== thisHTML) {
lastHTML = thisHTML;
$main.html(thisHTML);
}
});
}
Note that that's a fairly basic implementation of the fragment feature (it doesn't, for instance, strip out scripts the way load does). You may want to look at how load does its fragment stuff and replicate that (the joy of open source).
I posted a very much similar question yesterday but no one answerd so far. Now I have changed the functionality and stuck with the following problem. In this scenario, I have a RadWindow that i am opening from code behind file (.aspx page) on a button click. On this rad window I have a hidden field where I am setting value and now OnClientBeforeClose event I want to get the value from hidden field and assign it to a text box on my .ASPX page which is the parent page of this Rad Window. Could please anyone give me any idea how to do that. I have looked inot many examples on Telerik and StackOverflow but nothing working for me. Thanks in advance.
Rad Window Diclaration in my .Aspx.cs page
RadWindow window = new RadWindow();
window.Title = "Comments Pick List";
window.ID = "CommentsListPopUpRadWindow";
window.NavigateUrl = "CommentsList.aspx";
window.OnClientBeforeClose = "CommentsListPopUpRadWindowBeforeClose";
window.Skin = "Metro";
window.Behaviors = WindowBehaviors.Close;
window.KeepInScreenBounds = true;
window.VisibleStatusbar = false;
window.Modal = true;
window.Width = 750;
window.MinHeight = 510;
window.VisibleOnPageLoad = true;
window.EnableViewState = false;
RadWindowManager1.Windows.Add(window);
JavaScript function on RadWindow .ASPX page where I am setting value to the hidden field
function displayItem(id) {
var selectedText = document.getElementById(id);
document.getElementById('hiddenSelectedTextField').value = selectedText.innerText;
}
JavaScript OnClientBeforeClose function on my .ASPX parent page (to close the RadWindow) where I am trying to get value from the hidden field and set in the TextBox of parent page
function CommentsListPopUpRadWindowBeforeClose(oWnd, args) {
}
You can easily pass arguments to the RadWindow's Close function, from the child page:
function GetRadWindow() {
if (window.radWindow) {
return window.radWindow;
}
if (window.frameElement && window.frameElement.radWindow) {
return window.frameElement.radWindow;
}
return null;
}
function ChildClose() {
GetRadWindow().Close(document.getElementById('hiddenSelectedTextField').value);
}
and then retrieve the argument in the parent page by specifiying its OnClose function:
Add, in the aspx.cs file:
window.OnClientClose = "CommentsListPopUpRadWindow_OnClose";
and in the aspx parent page:
function CommentsListPopUpRadWindow_OnClose(radWindow, args) {
var arg = args.get_argument();
}
