I have this terminal but I can't seem to resize it (it's always the width of the page) and I can't write anything.
What's the problem here?
#terminal2 {
width: 50px;;
}
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/xterm/2.9.2/xterm.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/xterm/2.9.2/xterm.js"></script>
<div id="terminal2"></div>
<script>
var term = new Terminal();
term.open(document.getElementById('#terminal2'));
term.write('Hello from \033[1;3;31mxterm.js\033[0m $ ')
</script>
This works for me.

I want the border to increase, every time I press a button.
When the button is pressed, its 'value' is increased by 1. I want the value of the pixel-height of the border of the container to increase as well.
var i = 0;
var heightOfBorder = document.getElementById('test').style;
function buttonClick() {
document.getElementById('incrementValue').value = i++
heightOfBorder = "height: 500px";;
}
// document.getElementById("test").style.height = document.getElementById('incrementValue').value;
#test {
margin-top: 200px;
border: solid black;
width: 200px;
}

What am I doing wrong? I am learning to code. Also, side question, does anyone know of a good mentorship program?
Greetings!
You can get current height of the box using offsetHeight and on click add the input value to the box's style.height and remember to add the unit at the end - in your case 'px'.
Here is an example:
var i = 0;
var myEl = document.querySelector('#test');
var initialHeight = myEl.offsetHeight;
function buttonClick() {
document.getElementById('incrementValue').value = i++;
myEl.style.height = initialHeight + i + 'px';
}
<script>
var i = 0;
var heightOfBorder = document.getElementById('test').style;
function buttonClick() {
document.getElementById('incrementValue').value = i++;
let currHgt = heightOfBorder.getPropertyValue('height');
currHgt = +currHgt.slice(0, currHgt.length - 2);
heightOfBorder.setProperty('height', currHgt + i + 'px');
}
</script>
If you want to change height by i value.
just change var
heightOfBorder = document.getElementById('test').style;
to
var heightOfBorder = document.getElementById('test');
and
eightOfBorder = "height: 500px";
to
eightOfBorder.style = "height: 500px";
var i = 0;
var heightOfBorder = document.getElementById('test');
function buttonClick() {
document.getElementById('incrementValue').value = i++
heightOfBorder.style = "height: 500px";
}
// document.getElementById("test").style.height = document.getElementById('incrementValue').value;
#test {
margin-top: 200px;
border: solid black;
width: 200px;
}

I am trying to make a basic to do application.
Here is what I have done so far;
When the user clicks a button a prompt appears asking the user to enter a task.
The task will then be stored in an array
I have displayed the array in the console. However, I am having trouble displaying the array on the web page:
var toDoItems = [];
var parsed = "";
document.getElementById("addItem").onclick = function() {
var userInput = prompt("Enter your Todo: ")
toDoItems.push = userInput;
console.log(toDoItems);
}
<!DOCTYPE html>

<link href='https://fonts.googleapis.com/css?family=Lato:100,300,400,300italic' rel="stylesheet" type="text/css">
<link rel="stylesheet" type="text/css" href="css/style.css">

<title>To Do List</title>

<body>
<h1>My Tasks</h1>
<button id="addItem">Add item</button>
<div id="item-list">
</div>
<script src="js/script.js"></script>
</body>
</html>
The first thing is you need to use Array.push() and not Array.push = someVal. Then you can loop over to the values and create a list of elements in the HTML:
var toDoItems = [];
var parsed = "";
document.getElementById("addItem").onclick = function() {
var nHTML = '';
var userInput = prompt("Enter your Todo: ")
toDoItems.push(userInput);
toDoItems.forEach(function(item) {
nHTML += '<li>' + item + '</li>';
});
document.getElementById("item-list").innerHTML = '<ul>' + nHTML + '</ul>'
}
<head>

<title>To Do List</title>
</head>
<body>
<h1>My Tasks</h1>
<button id="addItem">Add item</button>
<div id="item-list">
</div>
<script src="js/script.js"></script>
</body>
You can use map() to map over the toDoItems and convert each items to html code and then use join() to combine the array into one string of HTML code.
Like this:
const HTML = toDoItems.map( item => `<li>${item}</li> ` ).join('');
document.getElementById("item-list").innerHTML = '<ul>' + HTML + '</ul>'
Edit: Fixed typo (should be join, not joint)
Loop over toDoItems, create a <p> tag and append it to #item-list:
toDoItems.forEach((item) => {
let p = document.createElement('p');
p.innerText = item;
document.querySelector('#item-list').appendChild(p);
});
You can use innerHTML for this
document.getElementById("item-list").innerHTML += "<p>" +userInput+"</p>";
demo : plunker
Check below I think this may help you
I removed style from your code for my convenience
<html>
<head>
<link href='https://fonts.googleapis.com/css?family=Lato:100,300,400,300italic' rel="stylesheet" type="text/css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<title>To Do List</title>
<script>
function myFunction(){
var toDoItems = [];
var parsed ="";
var userInput = prompt("Enter your Todo: ")
toDoItems.push = userInput;
document.getElementById("item-list").innerHTML=userInput;
console.log(toDoItems);
}
</script>
</head>
<body>
<h1>My Tasks</h1>
<button id="addItem" onclick="myFunction()">Add item</button>
<div id="item-list">
</div>
</body>
</html>
The Code above has an drawback: It erases the old value of userInput when you enter a new value in prompt().
I propose:
document.getElementById("item-list").innerHTML +=userInput+"";

before i reinvent the wheel, i wanted to know if anyone already has written a js/jquery library that allows user to select multiple div elements by left clicking and holding the hot keys (just like in windows)
Currently i have only this much

found an library that does exactly what i need to http://evulse.github.io/finderSelect/
Here the whole text inside the div get's red color. but I need only the "bar" word color to be changed
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title> new document </title>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#foo:contains('bar')").css('color','red');
});
</script>
</head>
<body>
<div id="foo">
this is a new bar
</div>
</body>
</html>
Could be done like that:
http://jsfiddle.net/PELkt/
var search = 'bar';
$(document).ready(function () {
$("div:contains('"+search+"')").each(function () {
var regex = new RegExp(search,'gi');
$(this).html($(this).text().replace(regex, "<span class='red'>"+search+"</span>"));
});
});
$("div:contains('bar')").each(function () {
$(this).html($(this).html().replace("bar", "<span class='red'>bar</span>"));
});
this will work surely
Please see Demo Here
You can use this way :
$(document).ready(function(){
// $("#foo:contains('bar')").css('color','red');
var text = 'bar' ;
var context = $("#foo").html();
$("#foo").html(context.replace(text,'<span style="color:red;">'+text+'</span>'));
});
Try this... prototype library:
<html>
<head>
<style type="text/css">
#content span {
background-color: yellow;
}
</style>
<script type="text/javascript" src="prototype.js"></script>
<script type="text/javascript">
Event.observe(window,'load',function(){
var htm = $('content').innerHTML;
$('content').innerHTML = htm.sub('bar','<font color=red>bar</font>');
});
</script>
</head>
<body>
<div id="content">
this is a new bar
</div>
</body>
You can do like this.
$(document).ready(function(){
var matchingTest = 'demo';
$("#container:contains("+matchingTest+")").each(function () {
$(this).html($(this).html().replace(matchingTest, "<span class='red'>"+matchingTest+"</span>"));
});
});
.red{
background:#eada93;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div id="container">
Hello this is a demo contents.
</div>
Solution with code snippet..
var text_change = 'bar';
$(document).ready(function () {
$("div:contains('"+text_change+"')").each(function () {
var regex = new RegExp(text_change,'gi');
$(this).html($(this).text().replace(regex, "<span class='red'>"+text_change+"</span>"));
});
});
.red {
color:#008000;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="text">this is a new bar and bar.</div>
Am using the below script to change the color of the script but showing 'font color="red">Hello world /font> like this.Is any possible way to change the alert text color..
<html>
<head>
<title>JavaScript String fontcolor() Method</title>
</head>
<body>
<script type="text/javascript">
var str = new String("Hello world");
alert(str.fontcolor( "red" ));
</script>
</body>
</html>
No. alert() accepts a string and renders it using a native widget. There is no provision to style it.
The closest you could get would be to modify the HTML document via the DOM to display the message instead of using an alert().
You can use JQuery to resolve your Problem

}});
});

<div id="dialog-message" title="My Dialog Alternative">
