Trying to add a second condition to a js function
original condition
if (content.length==elmnt.maxLength)
new condition
if (content.length==elmnt.maxLength && current form field value > 1400)
how do I code "current form field value > 1400" properly in javascript?
Full original code:
<SCRIPT TYPE="text/javascript">
function jumpField(elmnt,content)
{
if (content.length==elmnt.maxLength)
{
next=elmnt.tabIndex
if (next<document.forms[0].elements.length)
{
document.forms[0].elements[next].focus()
}
}
}
</SCRIPT>
Thanks!

Not sure if I fully understand what you are trying to achieve.
Are you looking for parseInt() to convert a string value? Like:
parseInt(document.forms[0].elements[next].value) > 1400

I have an object in Angular looking like this:
$scope.addEmployeeDepartments={ 5066549580791808=true, 6192449487634432=true, 7192449487634432=false}
How do I generate a comma-separated string like this
var ids="5066549580791808, 6192449487634432"
containing all the keys which are true ?
Btw, I am using underscore.js in other parts of my solution, so I don't know if that makes it easier.
thanks
Thomas

You can do this with reduce in one pass:
var collect_trues_in = function(a, v, k) {
if(v)
a.push(k);
return a;
};
var csv = _($scope.addEmployeeDepartments).reduce(collect_trues_in, [ ]).join(', ');

Can anyone explain what is meaning of this Regular Expression?
/^(https?):\/\/(www\.)?[a-zA-Z0-9\-\.]+\.[a-zA-Z0-9]{2,3}[a-zA-Z0-9\-\#\.\/\?]*$/

Finally I have founded my solution:
function validateURL(url)
{
var re = /^(https?):\/\/(www\.)?[a-z0-9\-\.]+\.[[a-z0-9\-\.\/]{2,}]*$/;
if (!re.test(url))
{
return false;
}
else
{
return true;
}
}
this function return true if your url contain these:
part 1. https or http
part 2. www or not (means optional).
Below image exploring in more depth.
I am wrong?

I've tried the following and works fine for me.
var url = "https://www.xyz.xe";
function validateURL(url)
{
var urlregex = new RegExp("^(http|https)\://([a-zA-Z0-9\.\-]+(\:[a-zA-Z0-9\.&%\$\-]+)*#)*((25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])|([a-zA-Z0-9\-]+\.)*[a-zA-Z0-9\-]+\.(com|edu|gov|int|mil|net|org|biz|arpa|info|name|pro|aero|coop|museum|[a-zA-Z]{2}))(\:[0-9]+)*(/($|[a-zA-Z0-9\.\,\?\'\\\+&%\$#\=~_\-]+))*$");
return urlregex.test(url);
}
validateURL(url);
Returs false when url="https://www.xyz.x" and true when url="https://www.xyz.xe"

I am new to jQuery. I have a text field and I want to validate this field so that it only takes character and alphanumeric values, however if you put in a numeric value it will show a message. How should I implement this?

$('#textfieldid').on('change', function(event) {
var text = $('#textfieldid').text();
//some validation code here
});
By the way, JQuery is a javascript library, not Java (which you have tagged).

Using regex, validations can be done.
var password = document.getElementB;
var letter = /[a-zA-Z]/;
var number = /[0-9]/;
if(number.test(password) && letter.test(password)){
//success
}else{
//error
}
Here password is the value which is returned from the field

Is there a way to use the following code:
$(document).ready(function () {
$('sd').hover(function() {
$(this).addClass('a');
}, function() {
$(this).removeClass('a');
});
});
without including the jquery file in my code? For example, is there a way to do exactly the same thing with pure javascript?

Sure, modified from this answer: Change an element's class with JavaScript
window.onload = function() {
var elements = document.getElementsByTagName('sd');
for (var i in elements) {
if (!elements.hasOwnProperty(i)) continue;
elements[i].addEventListener( 'mouseover', function() {
this.className += 'a';
}
elements[i].addEventListener( 'mouseout', function() {
this.className = this.className.replace( /(?:^|\s)a(?!\S)/g , '' );
}
}
}
