As you see the outline is collapsed in the following sample: var input = document.getElementById('input'); var output = document.getElementById('output'); input.addEventListener('input', function() { output.value = input.value; }); output { display: block; font: 20px Arial; outline: 1px solid green; } <input id="input"> <output id="output"></output> DEMO How can I prevent it? Do I need to give the output a fixed height? If so, what value should I give to the height if I want it to be just as high as the text height — not an arbitrary number? Is there a

Scenario Every semester my students need to take at least one test. The following form gives the right average grade of a student: <!DOCTYPE html> <html lang="en"> <head> <title>Average Grade</title> </head> <body> <form> Math: <input type="number" id="test1"> <input type="number" id="test2"> <input type="number" id="test3"> <output id="average"></output> <br> <input type="button" value="Calculate" id="calcBtn"> </form> <script> document.g

Steps to reproduce the issue: In your browser Settings select Continue where you/I left off under On startup. Navigate to the demo. Check the checkbox. Edit the text. Close your browser and reopen it. Or duplicate/clone the tab. Now as you see the checkbox is checked, but the textarea isn't colored. I tried it in the latest version of Chrome and Opera in Windows 10. I'm not sure about Safari, but it probably behaves the same way. Questions: Why does it happen? What's a cross-browser solution?

Consider this: <input type="file" id="filePicker"> <script> document.getElementById('filePicker').onchange = function() { alert('Hi!'); }; </script> Even if you choose the same file and the filePicker value doesn't change, you'll see the alert box in Firefox. Any solutions?

Yes, that seems to be the problem. Then I need to put my question this way: How to reload the parent frame that's located on a different frame?

Sample parent code: <!DOCTYPE html><html><head><meta charset="UTF-8"><title>Parent</title></head><body><iframe src="https://dl.dropboxusercontent.com/u/4017788/Labs/child.html" width="200" height="100"></iframe></body></html> See it in action: https://googledrive.com/host/0B5jOXzxlxbMhYVF3b0lubjlDWm8/parent.html Sample child code: <!DOCTYPE html><html><head><meta charset="UTF-8"><title>Child</title></head><body><button onclick="myFunction();">Try it!</button>

Thanks for the answer, but: I don't know how to do it using cURL. Would you mind providing a snippet to use as a template? Doesn't it break the layout when the target page has non-absolute URLs and relative links?

When I embed an external HTTP iframe into my HTTPS page, I get a mixed content error message: <iframe src="http://www.example.com"></iframe> To work around this limitation I'd like to echo the external page from my own domain. How should I do that? Thanks!

Sample form: <!DOCTYPE html><html><head><title></title><style type="text/css">* {font:13px arial; color:white;}body {background:black;}label {display:inline-block; width:50px;}input, textarea {margin:0; border:1px solid red; padding:0; background:green;}textarea {width:300px; height:100px;}</style></head><body><form action="#"><div><label for="entry_0">Name</label><input type="text" id="entry_0"></div><div><label for="entry_1">Email</label><input type="text" id="entry_1"></div

I tried id, but it didn't work: var iframe = document.getElementById('target'); function displayResult() { if (textarea.value) { iframe.open(); iframe.write(textarea.value); iframe.close(); } window.setTimeout(displayResult, 10); } I also updated my question for clarification.

I wonder why the following sample code doesn't work properly: <!DOCTYPE html><html> <head> <title></title> <style type="text/css"> textarea, iframe { display:block; width:300px; height:100px; margin:3px; padding:3px; border:1px solid #CCC; } </style> </head> <body> <textarea id="field" onfocus="getFocus();" onblur="loseFocus();">This is some text.</textarea> <iframe name="target"></iframe> <script> var textarea = document.getElementById('field'); var iframe = window.target.do

jQuery validation: display the focused field error message
Rain Lover replied to Rain Lover's topic in JavaScript
Thanks for the answer! Do you know how I can display the focused field error? -
Objective: I'd like to display the focused field error message in a container. What I've done so far: <!DOCTYPE html><html><head><title></title><style type="text/css">label {display:inline-block; width:60px;}</style><script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script><script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js" type="text/javascript"></script><script type="text/javascript">$(document).ready(function(){$("form").validate(

Thanks for the answer, but I still don't understand the difference between the first and second example although I read your explanation a few times.
-
In the second example the parent width is smaller than the child total width and the scrollbars should appear.
