I need to get photos using GIPHY API, I have the following function:
function callApi(input) {
var url1 = `https://api.giphy.com/v1/gifs/random?api_key=0zCoIz5c8dbanGyiAHnA0pSUe3bcA9sf&tag=${input.value.toLowerCase()}&limit=1`;
var url2 = "https://api.giphy.com/v1/gifs/random?api_key=0zCoIz5c8dbanGyiAHnA0pSUe3bcA9sf&tag=dog&limit=1";
var xhr = $.get(url2);
xhr.done(function(jsonObj) {
alert("Success!");
document.getElementById("genImage").src = jsonObj.data.images.original.url;
}).fail(function() {
alert("erro");
}).always(function() {
alert("...");
})
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script type="text/javascript" src="main.js"></script>
<meta charset="utf-8">
<title>Test</title>
</head>
<body>
<form id="query-form">
<label for="query">KEYWORD</label>
<input name="query" type="text">
<input type="submit" id="button" value="GENERATE" onclick="callApi(query)">
</form>
<img id="genImage" src="">
</body>
</html>
So, the problem is that $.get() function doesn't respond at all, even always() callback function does not get executed.
When I try this particular URL in the Postman application, I get the response (json object) and I can access the data.images.origianl.url property it is there.
When I try the following line of code in the console :$.get("https://api.giphy.com/v1/gifs/random?api_key=0zCoIz5c8dbanGyiAHnA0pSUe3bcA9sf&tag=dog&limit=1"); I get the response with the status code 200, so it should work in the main.js file, but in my case it doesn't.
I have two variables url1 and url2 this is because, in my first tries I did not get anything with the url1, but getting the success with the url2. After some time I didn't get anything using two of them.
What is the problem? How can it be that I can get responses from Postman and from the console using the same URLs, but do not get them with actual code?
Thank you for your patience!
This is a common problem, understanding the difference between type button and type submit.
Submit will submit the form. Whereas button will just process the event handlers assigned.
Change
<input type="submit"
to
<input type="button"
function callApi(input) {
var url1 = `https://api.giphy.com/v1/gifs/random?api_key=0zCoIz5c8dbanGyiAHnA0pSUe3bcA9sf&tag=${input.value.toLowerCase()}&limit=1`;
var url2 = "https://api.giphy.com/v1/gifs/random?api_key=0zCoIz5c8dbanGyiAHnA0pSUe3bcA9sf&tag=dog&limit=1";
var xhr = $.get(url2);
xhr.done(function(jsonObj) {
alert("Success!");
document.getElementById("genImage").src = jsonObj.data.images.original.url;
}).fail(function() {
alert("erro");
}).always(function() {
alert("...");
})
}

I am currently writing a function that writes a bit of code for me based on an input. I am currently working on creating the input and the code that pastes the input, but whenever it writes, it shows up as undefined. This is the code.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Javascript YAML Generator</title>
</head>
<body>
<form class="yamlform" action="index.html" method="post">
<input type="text" name="appname" value="Name">
<button type="submit" onclick="writeAppName()">Submit</button>
</form>
<script type="text/javascript">
var appname = document.getElementsByName("appname").value
function writeAppName() {
document.write(appname)
}
</script>
</body>
</html>
NOTE: This is not my final version of the code, at the moment I just want a system for writing an input value that I can duplicate. Final version will be using document.getElementbyID.
document.getElementsByName returns colection. Use document.getElementsByName("appname")[0].value.

You need to refer to the first element with name "appname", because it could be a collection. Also I but the assignment for appanme variable inside of the function, this will make it so appname isn't being assigned to "Name" right away and is instead assigned to whatever is in the text box when you click the botton

The problem is with your document.getElementsByName
It is possible that multiple elements would have same name.
While using document.getElementsByName, there might be multiple elements instead of a single element present in DOM with similar name, so document.getElementsByName returns an array (a list of elements) and not a single element
To use different elements of the Array, use
document.getElementsByName("appname")[0] // For first element with name
document.getElementsByName("appname")[1] // For second element with name
// and so on
So in your code, you would use
var appname = document.getElementsByName("appname")[0].value;
I have a code-
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
function testFunction(){
var stringCode = '#abc[0][0]';
console.log(stringCode);
result = $(stringCode).val();
console.log(result);
}
</script>
</head>
<body>
<input type="hidden" id="abc[0][0]" value="5" readonly="true/">
<input type="button" onClick="testFunction()"/>
</body>
</html>
My Main problem is-
When i click the button and look to browser console so i get undefined
as result of console.log(result). How to fix it so the code can show 5
as the result not undefined ?
Thank you.
You can do it like below (In jquery which is used in your code):-
function testFunction(){
result = $('input[id ="abc[0][0]"]').val();
console.log(result);
}
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>
<body>
<input type="hidden" id="abc[0][0]" value="5" readonly="true/">
<input type="button" onClick="testFunction()" value = "ClickMe!"/>
</body>
</html>
Note:-
This is called [attribute=value] selector
Check all available different selectors
If things are simple then try simple way
function testFunction(){
var f = document.getElementById("abc[0][0]");
result = f.value;
console.log(result);
}
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<input type="hidden" id="abc[0][0]" value="5" readonly="true/">
<input type="button" onClick="testFunction()" value = "ClickMe!"/>
</body>
</html>
I wanted to modify something in my code and don't really know how to make this work... my code is kinda huge so I am going to explain what I want with an exemple :
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="stylesheets/application.css">
</head>
<body>
<label>Enter value : </label><input type="text" maxlength="512" id="reg_expr"/>
<div id="button">OK</div>
<div id="nfa"></div>
<script src="script1.js"></script>
<script src="script2.js"></script>
<script src="script3.js"></script>
</body>
</html>
So this is my HTML code, so what I want to do is NOT execute these 3 scripts until the user enters a value in the text input and clicks on OK. That value will be used in the js files, so i have to get the value after I click OK.
Can someone explain how this has to work ?
EDIT : problem was with jQuery that was not executing on Electron, solution : http://ourcodeworld.com/articles/read/202/how-to-include-and-use-jquery-in-electron-framework
For starters I would suggest changing; <div id="button">OK</div> to <button id="button">OK</button>.
I would then suggest to put each of those scripts into functions instead, then you can use the 'onClick' event from the button attribute as follows;
<button id="button" onClick="s1Func();s2Func();s3Func();">OK</button>
A better way would be to have one function call 'init' or something appropriate that then calls the 3 scripts/functions and have your buttons onClick even call that one initialization function.
JSFiddle Example:
https://jsfiddle.net/JokerDan/h7htk9Lp/
I would recommend you to load the scripts dynamically after you click on the button. This can be done via jQuery: https://api.jquery.com/jquery.getscript/
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="stylesheets/application.css">
<title>NFA2DFA</title>
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
</head>
<body>
<label>Enter value : </label><input type="text" maxlength="512" id="reg_expr"/>
<div id="button" onclick="loadScripts();">OK</div>
<div id="nfa"></div>
<script>
function loadScripts() {
// Is the input empty?
var value = $("#reg_expr").val();
if (value.length != 0) {
// Loads and executes the scripts
console.log(value); // Displays the value of the input field
$.getScript("script1.js");
$.getScript("script2.js");
$.getScript("script3.js");
}
}
</script>
</body>
</html>
You can use a button tag instead of input tag. I suggest you to use onClick event like this:
<button type="button" onclick="yourFunction()">Click me</button>
When the users click the button yourFunction() is call.
The result is this:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="stylesheets/application.css">
<script src="script1.js"></script>
<script src="script2.js"></script>
<script src="script3.js"></script>
</head>
<body>
<label>Enter value : </label><input type="text" maxlength="512" id="reg_expr"/>
<button type="button" onclick="yourFunction()">Click me</button>
</body>
</html>
I have the following code that works:
<html>
<head>
<script>
function loaded(){
oFormElement = document.forms['test form'].elements["txtStatus"];
oFormElement.value = "just loaded";
}
</script>
</head>
<body onload="loaded()">
<p>my first socket.io test</p>
<form id = "test form">
<input type="text" id ="txtStatus" value="">
</form>
</body>
</html>
now, if I include the reference to socket.io, it stops working
<html>
<head>
<script src="socket.io/socket.io.js">
<script>
function loaded(){
is this because socket.io handles from elements in it's own way, or is because the browser cannot find socket.io ? Is there any way to debug this/fix this ?
You need to close the first <script> tag...
<html>
<head>
<script src="socket.io/socket.io.js"></script>
<script>
function loaded(){
// ...
I am using getJSON to send a request to server and fetch response. When I send an string of text like 'firstname=x' to the server, it works fine, but when I use '$('#input').val()' as input data to the server, it returns nothing as response.
Here is the jquery code
<!DOCTYPE html>
<html>
<head>
<title>Request in getJSON</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="jquery-1.8.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#button').click(function(){
var req=$('#query').val();
var data='firstname=req';
$.getJSON('http://..../server.php?callback=?', data,function(res){
alert('Your name is '+res.fullname);
});//getJSON
}); //onclick
});//on document ready
</script>
</head>
<body>
<h1> Enter Name </h1>
<input type='text' id='query' />
<input type="button" id="button" value="submit" />
<div id="results"></div>
</body>
</html>
Hope you can help me
Thank you
Try with this one:
$(document).ready(function(){
$('#button').click(function(e){
e.preventDefault();
var data={firstname : $('#query').val()}; //<--------try like this
$.getJSON('http://..../server.php?callback=?', data,function(res){
alert('Your name is '+res.fullname);
});//getJSON
}); //onclick
});//on document ready
