I have an iFrame in HTML code, and I created a script tag that I set on a submit button. I want the iFrame to be visible when I click on the submit button, but that is not working. Here is my HTML code:

</form>
<br>
<div id="outerdiv" >
<iframe src={{results}} id="innerIframe" style="visibility: hidden;" scrolling="yes"></iframe>
</div>
</body>
</html>
{{results}} is the URL that is passed by the user in python Flask. So in the form the user types in a word, which then joins it to a URL and performs a search. The search works perfectly, but when the page is loaded on startup, it shows Not Found, the requested URL has not been found... and I understand why that happens as the URL hasn't been loaded yet. So I want to make the iFrame invisible, and once the submit button is pressed, the frame can be visible.
I have tried with jQuery as well, but it did not work.
All help and advice will be highly appreciated.
First pass "event" when you call the onClick function in your HTML code like this *onclick="showIFrame(event)
Then in your function, you accept the "event" as a parameter like this *function showIFrame(event) {
A click button most times trigers your page to refresh, so you have to stop that by preventing the default action. Add "event.preventDefault()" to your function like this *event.preventDefault()

Hello, I am trying to add a onclick or click event that will allow someone to input a city and retrieve said city's weather information. I had added a event listener to the api function however it does not seem to work. Please help?
You've got a few problems with your html and your js.
First with your js. In your file, all the code is in 'the main' and is being executed as soon as the file loads. You dont want that, you want to create a function so you can use it to link it with the 'onclick' event. You that simply by wrapping your code in a function like this:
function myfunction() {
$.getJSON("https://api.openweathermap.org/data/2.5/forecast?q="+City+"&appid=dc171ae0b3b507207c6605cbab0a5f98",
function(data){
console.log(data);
var icon ="https://openweathermap.org/img/w/" + data.list[0].weather[0].icon +".png";
var temp=Math.floor(data.list[0].main.temp);
var weather=data.list[0].weather[0].main;
var city=data.city.name;
var date= data.list[0].dt_txt;
var humidity=data.list[0].main.humidity;
var wind=data.list[0].wind.speed;
$(".icon").attr("src",icon);
$(".weather").append(weather);
$(".temp").append(temp);
$(".city").append(city);
$(".date").append(date);
$(".humidity").append(humidity);
$(".wind").append(wind);
});
}
After that, I see you've got a variable called City inside your request which has no value. Your code has to know what is that and be able to retrieve its value. For that we call the 'document' object which contains the input and take its value. Like this:
var City = document.getElementById('input').value;
console.log(City) // Print it for good meassure
With that inside your function, every time you click the button, the value is going to be updated and do the request.
Now, in your html you need to change your button's type property. If its of type submit, the form is submited and the page reloaded (The whole form is unnecesary really but I'll leave it in as to not change your code too much). In this case you want your button to be of type 'button' so it only acts as a button when pressed. Like this:
...
<form class="searchInput" style="margin:auto;max-width:300px" >
<input id="input" class="input1" type="text" placeholder="Search..." name="search">
<button onclick="myfunction()" id="button" class="button1" type="button"><i class="fa fa-search"></i></button>
</form>
...
With all that your code should work, retrieve your json and display the information you want on screen.
I hope all of this helps!
I'm trying to create a selectable list that when you click on an item, it displays an input field that you can use to edit the description but until the item is clicked on, the input field is hidden.
However, when I select an item and then click on the input field, it unselects the item and the input field is hidden again.
I've recreated the issue here with just one list item. How can I allow for the user to click in the input field without triggering the jQuery function?
Also, the user will be able to click multiple items in the list so I've updated the jsbin with a second item.
If you don't want to change the html arrangement of the input , you can prevent the event propagation on click of the input element to its parent which in turn will avoid any class toggle.
The only addition you need is this.
$('.fund input').click(function(e) {
e.stopPropagation();
});
Here is the working sample
$('.fund').click(function() {
$(this).toggleClass('selected');
});
$('.fund input').click(function(e) {
e.stopPropagation();
});
* {
font-family: 'Lato', sans-serif;
}
.fund {
background-color: #fff;
width: 500px;
border: 1px solid #444;
height: 50px;
padding: 0 10px;
border-radius: 3px;
}
.fund:hover {
background-color: #efefef;
cursor: pointer;
}
.fund .description,
.fund .alt-description {
width: 50%;
float: left;
}
.fund .description {
line-height: 50px;
font-size: 12px;
letter-spacing: 1px;
text-transform: uppercase;
font-weight: 700;
color: #555;
}
.fund .alt-description {
visibility: hidden;
line-height: 50px;
font-size: 14px;
}
.fund .alt-description input {
height: 30px;
font-size: 12px;
}
.fund.selected {
border: 1px solid #00cc00;
}
.fund.selected .description {
color: #00cc00;
}
.fund.selected .alt-description {
visibility: visible;
}
<!DOCTYPE html>
<html>
<head>
<meta name="description" content="[be able to click in input but don't toggle div]">
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<link href='https://fonts.googleapis.com/css?family=Lato:400,300,700' rel='stylesheet' type='text/css'>

<title>JS Bin</title>
</head>
<body>
<div class='fund'>
<div class='description'>
Fund Name
</div>
<div class='alt-description'>
Description:
<input type='text' value='Fund Name'>
</div>
</div>
</body>
</html>
This will do the trick:
$('.fund').click(function() {
$('.fund').removeClass('selected');
$(this).addClass('selected');
});
The issue is that you have alt-description within fund, so anytime you click on "fund" it will toggle the show hide of your alt-description input. Move the alt-description out of the fund class. Otherwise make the trigger description instead of fund.
<div class='fund'>
<div class='description1'>
Fund Name
</div>
</div>
<div class='alt-description1'>
Description: <input type='text' value='Fund Name'>
</div>
Here I change the javascript a little.
$('.fund').click(function() {
if(!$(this).hasClass('selected')){
$(this).toggleClass('selected');
}
});
So when ever the div with the .fund class has a class selected don't toggle the class.
I am trying to make all my JavaScript external including the onclick for the submit button, I have a commented out window.onload function that I can't get to work. When I remove the onclick="checkInput();" from the submit input and uncomment the window.onload event in the script , my form doesn't work.
Can someone explain what I am doing wrong besides being new to JavaScript.I have included a working snippet, just not external, thanks for any guidance.

You have to wait for the DOM to finish loading before you can query it to find DOM elements and atach events.
The simplest fix would be placing your <script> at the end of body.
Another fix is to attach handlers in window onload event ( that's how it works in code snippet below)
In code snippet provided in question the the way window.onload was attached was unclear. Also at the end of script expression Palindrome(str); raised error as var str is undefined, so i've fixed it.
See working snippet below:
document.getElementById('submit').onclick = function(evt) {
checkInput();
}
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
window.onload = function(){
document.getElementById('submit').onclick = function(evt) {
checkInput();
};};
function checkInput() {
alert('Check input fired');
}//end check input
</script>
</head>
<body>
<div id="main">

I am trying event.preventDefault() or return false.
None of them working when I have ? at the end of my url.
My url is http://127.0.0.1:789/
but, whenever I hit enter of click on button. It will refresh the page and url becomes
http://127.0.0.1:789/?
and no matter what I do it will continue to refresh the page. I check all the questions.

I tried everything nothing works unless i manually put # at the end of url.
You should place your script in the document ready function (it is currently executed before the DOM is finished loading.)
$(function() {
$("form").on('submit', function(event){
event.preventDefault();
return false;
});
});
The question mark is because the form sends a GET request to the current page.
But it doesn't work. You can see I'm trying to change the class of the div containing season.png onmousedown and revert it onmouseup.
What am I missing?
Thanks.

It's working just fine. There is nothing wrong with the code that you posted, so if you can't see it there has to be something wrong with your css.
I used this to test the code:
<html>
<head>
<title>Test</title>
<style>
.winter { border: 1px solid blue; }
.spring { background: yellow; }
.summer { background: green; }
</style>
</head>
<body>
<div class="winter spring" onmousedown="this.className='winter summer'" onmouseup="this.className='winter spring'">
<img src="Resources/season.png" />
</div>
</body>
</html>
It works for me so I guess you need to run some checks on your code. Make sure your css is included.
Post the complete code you are using so we can look for errors.
This is the code I used:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>onmouseevents on div</title>
<style type="text/css">
body
{
background-color: #FFF;
color: #000;
}
.page
{
margin: 10px auto;
width: 640px;
}
.winter
{
background-color: cyan;
}
.spring
{
color: magenta;
}
.summer
{
color: yellow;
}
</style>
</head>
<body>
<div class="page">
<div class="winter spring" onmousedown="this.className='winter summer'" onmouseup="this.className='winter spring'">
Cats!
</div>
</div>
</body>
</html>
As an alternative - I have used the hover pseudoselector for this.
Here's a personal example:
.sidebar ul.sidebuttons li a
{
font: bold italic x-large/1.1 trebuchet ms,verdana,sans-serif;
display: block; /* effect should be in a new box not inline */
text-decoration: none; /* turn off link underlining */
color: yellow;
background: black url(sidebar_off.png) no-repeat center;
padding: 10px 10px 10px 5px;
margin: 0px 0px 20px 0px;
border: white outset;
border-width: 2px 2px 2px 0px;
text-align: right;
text-transform: lowercase;
}
.sidebar ul.sidebuttons li a:hover
{
background: yellow url(sidebar_on.png) no-repeat center;
color: black;
border: black inset;
text-decoration: none;
border-width: 2px 2px 2px 0px;
}
The HTML looks like:
<div class="sidebar">
<ul class="sidebuttons">
<li>Go Somewhere</li>
If you're having trouble, try Firefox Web Developer add-on or something similar to check the style information on that part of the page. It might not be triggering what you think it should be triggering.
<style>
.summer{ background-color:red;}
.spring{ background-color:blue;}
.aa{ font-size:18px;}
.bb{ font-size:36px;}
</style>
<div class="aa spring" onmousedown="this.className='summer aa'" onmouseup="this.className='spring bb'">
aaaaaaaaa
</div>
I test this code, it works well.
I think, not javascript problem. Try to check css, or other things.
Maybe put js code and css code on the img is what you need.
It's very easy with jQuery:
$(".winter").mouseup(function() {
$(this).addClass("spring");
$(this).removeClass("summer");
},function(){
$(this).addClass("summer");
$(this).removeClass("spring");
});
The Javascript file I was using was a very inflexible library. I solved the problem a different way.
