<script>
document.write(3.25 + 1000);
document.write('<br>' + 5 - 1000);
var1 = "Buna";
var2 = "Ziua";
document.write("<br>Concatenare siruri:" + var1 + var2 + '<br>');
a = true;
document.write(a);
var = fructe['mere', 'pere', 'caise'];
document.write('<br>' + fructe[1]);
</script>
</body>
</html>
You should fix this line:
var = fructe['mere', 'pere', 'caise'];
To
var fructe = ['mere', 'pere', 'caise'];

Just need help getting the vanilla javascript version of $('#yourname').val(); part of var name=$('#yourname').val();
There are numerous selectors of JavaScript in order to do this.
You can find some here, here, and here.

<input type="hidden" id="someID" value="625413">
<script>
var a = document.getElementById("someID").value;
var b = $("#someID").val();
var c = document.querySelector("#someID").value;
alert(a + " / " + b + " / " + c);
</script>
</body>
</html>
var a = document.getElementById("someID").value; is the 'classic' example of Vanilla JavaScript.
I need help with JS and html. I need to store <input type = "date" id = "date"> in JS var. If you try to store the date in simple var and try to print it instead of your chosen date you get printed "undefined" :
$("#printDate").click(function(){
var dateVar = ($("#date").val());
$("#results").append("<p>" + dateVar + "</p>")
});
If you try to store the date in the dateVar using new Date() you get printed "Invalid date":
$("#printDate").click(function(){
var dateVar = new Date($("#date").val());
$("#results").append("<p>" + dateVar + "</p>")
});
Thank you for any kind of help!

The only problem with your code is you are targetting wrong id i.e $("#date") instead of $("#dateInput")
<div id="results"></div>
<input type="date" id="dateInput">
<button id="printDate">PrintDate</button>
<script>
$("#printDate").click(function(){
var dateVar = new Date($("#dateInput").val());
$("#results").append("<p>" + dateVar + "</p>")
});
</script>
You have a typing error.
I am attempting to use Google Feed API to display three current event listings for our homepage. This is to circumvent some of the issues we are having with a third part calendar application.
However, with the feed limit set to 3, the only listings that will show up for me are from Jan. 18. Is there a way to make the code show only current or future events?
Thanks in advance for any help.

JSFiddle code not working in my own page

Closed 8 years ago.
my code is working in jsfiddle but not working in the browser i dont know what i missed here could you please check it and tell me the solution. i google it but i am not getting correct solution please help me
this is jsfiddle link http://jsfiddle.net/pLTrJ/9/

updateTheDiv(9,0);
function updateTheDiv(inRange, inMin) {
random = (Math.random()*inRange+inMin)|0;
theDiv.innerHTML = random;
var nextCall = (Math.random()*1000)|0;

jsfiddle has wrapped it automatically in the onload event. You haven't done this in your HTML page, so when it runs in the browser you're trying to get hold of the div before it's been rendered, so theDiv is null.
The below should work:
<!doctype html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"> </script>
</head>
<script type="text/javascript">
window.onload = function () {
var random = 0;
var theDiv = document.getElementById("showVal");
updateTheDiv(9, 0);
function updateTheDiv(inRange, inMin) {
random = (Math.random() * inRange + inMin) | 0;
theDiv.innerHTML = random;
var nextCall = (Math.random() * 1000) | 0;
setTimeout(function () {
updateTheDiv(inRange, inMin);
}, nextCall);
}
}
</script>
<body>
<div id="showVal">
</div>
</body>
</html>
Try this in your Browser ;)

(I just put the script to the bottom. So the script loads after your element is set.)
my question is I need to create a string from the result of event.content. Event.content returns me an entry including html tags. I can use it like container.innerHTML = event.content. I need the event.content as a string. I tried to do something like this:
var a = '' + event.content;
But it doesn't work. Here the result of event.content:
<img src="http://image.weather.com/web/common/wxicons/31/30.gif?12122006" alt="" />Partly Cloudy, and 84 ° F. For more details?
I can't convert this into string in javascript. Is it possible? I also tried String(event.content). Ok I put my whole code.

Your regex is invalid. It does not match the string from entry.content. The reason for this is °. Change your code to this:
var regex = /<img.*?src="(.*?)".*?>.*?([0-9]+)/;
var results = regex.exec(entry.content);
var html = '<img src= ' + results[1] + ' alt="" /> ' + results[2] + ' °';
DEMO
Probably you forgot to escape either the sigle quotes or double quotes with a backlash? This is a valid string -
var string="<img src=\"http://image.weather.com/web/common/wxicons/31/30.gif?12122006\" alt=\"\" />Partly Cloudy, and 84 ° F. For more details?";
