Get The Length Of String Function Not Working

Aug 16, 2010

i used the String.length(string) function in javascript to get the length of string but nothing happened. It doesn't give me a value when i tried to view the result using an alert function. Actually, this kind of problem does not only exist with the length function, it's also the same with the trim(). I have not tried using other functions but perhaps it won't also work. What could be the possible reason for this?

String.Length Function Returns Undefined?

Mar 27, 2011

When I run the following code, the .Length function returns "undefined."

Using the typeof function, I know that JS is treating the variable as a string.

String Length?

Aug 10, 2006

The following function takes three different fields (which combined make up a phone number) and tests it to make sure that all the characters entered are integers. If this is true, it sets form.Phone.value = entirephonenumber. I would like to incorporate an additional test which, after determining that all characters in the string are integers, checks to make sure that the string length is 10. If it is less than 10 or more, I want the entire function to return false and display an error message (the same one is fine..) Code:

Mar 16, 2009

i have a xml file where i do the following query:

entry_03_title=doc.documentElement.getElementsByTagName("entry")[2].getElementsByTagName("title")[0].firstChild.data;

now having the variable "entry_03_title" i would like that javascript do this:

if(entry_03_title.length>30) entry_03_title.length=6

IE Reporting Wrong String Length

Aug 22, 2007

This is quite mysterious. I have several list items like this:

HTML Code:
<li>Private</li>
I am looping through them all trying to get the text inside each list item for a comparison with a string from elsewhere.

Javascript Code:
var coresubmenu = document.getElementById('core').getElementsByTagName('li');for (var i = 0; i < coresubmenu.length; i++) { coresubmenu[i].onclick = function() { if (this.firstChild.nodeValue == 'Private') { // fail } alert(this.firstChild.nodeValue.length); // alerts 8 }}

IE alerts one more than the actual length in all cases. Google hasn't brought anything up for me on this one - any ideas?

JQuery :: Live Output On Database String Length

May 28, 2011

How would I go about outputting something when a database value is being changed?

e.g. If im typing in a text field, which is saving what ive typed every time i keyup into a database field, it then shows on another page on another user computer as "User is typing something in field X"?

If no typing is happened, i.e. the database field value is not changing, nothing is echoed out.

It would also be cool to have something show "User is deleting text from field X" when the field value is getting shorter.

In pseudo code, something like if the value of database string is bigger than 100ms ago, echo out "user is typing something in", and conversly, if string is getting shorter echo out "user is deleting stuff".

Display Form ID Function - Length Is Null

Jul 25, 2010

For some reason i'm getting the error of "length is null". Which is from this.
function display_form(id) {
//Create some variables
var html = "";
var container = "form_container";
var menu = load_menu(id, false);

//Get id
for ( var i = 0; i < menu.length; i++ ) {
alert(i);
}

http = getHTTPObject();
http.onreadystatechange = function() {
if ( http.readyState == 4 && http.status == 200 ) {
document.getElementById(container).innerHTML = http.responseText;
} else {
document.getElemenyById(container).innerHTML = "Loading...";
}}
http.open( "GET", "includes/forms.php?form=" + id );
http.send();
//Watch input fields
//login_listener();
}/*

Here is the function:
function load_menu(menu, return_d) {
//Availible menus
var data = [];
data [ 'login' ] = [ 'Login', 'Register', 'Recovery' ];
data [ 'settings' ] = [ 'Profile', 'Account', 'something' ];

if (return_d == false) {
return data[ menu ];
} else {
//Menu container ID's
var cons = Array('menuitem1','menuitem2','menuitem3');

for ( var i = 0; i < cons.length; i++ ) {
document.getElementById(cons[i]).innerHTML += data[ menu ] [ i ];
}}}

Extra info:
id = login
menu = login

Call A Variable From Pieced Together String?

Jun 23, 2011

I'm sure it's just a syntax problem. You can ignore most of this function because most of it works. The part I'm asking about is the "coordinates" variable 4th line from the bottom. The "office3" variable is a dynamically populated office number. I have the office numbers all defined as variables somewhere else but since I can't just name the variables as numbers I had to put a $ in front of them. Basically I'm trying to call the office number variable, $1656 for example. So "coordinates" is meant to be equal to "$+the chosen office number".[code]...

Function To Call A Function In All Child Frames

Oct 16, 2006

I have a document that can contain any number of iframes which have
further copies of the same document (and so on). In practice, we
shouldn't ever have frames within frames, but I'd like to make the
implementation a general case.

Various of the functions in the parent document need to call themselves
in the child documents with the same parameters as they've just been
passed.

Now, I can stick a loop in each function that goes throught the
window.frames array and calls the function for each frame, but for I'd
like to write a function to do this.

It's at this point that my brain explodes. If I limit it to a single
parameter we can do:
