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
in other words if the title is bigger than 30 chars long make it 6 chars, but this doesn't work.
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:

if (form.SSN.length != "9") {
alert("SSN must be nine digits long");
form.SSN.focus()
return false; }
It always displays the alert even if it does equal 9 digits long. I'm new to javascript so if this is a really simple error just go with it....
How can I call a function in javascript like code...

Does it exist a method to count string characters?
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?
View 1 Replies View RelatedThis 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?
When I run the following code, the .Length function returns "undefined."
var strTest = 'test';
alert(strTest.Length);
Using the typeof function, I know that JS is treating the variable as a string.
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".
I have a free script I have downloaded and I can't figure out how to edit it so that I can change the color of the text to whatever I want it to be and also so that the length of the scrolling text (I am not sure if scrolling is the right term) can be changed. For some reason the text does not go all the way to the end of the page on the right it stops quite a way before.Here is the code:

So I am receiving a string with a name and I want to turn that name into a variable name.

I'm curious if there is a possibility of being able to search the whole document for a specific string using replace("that", "this") for example to find any reference to "this" and replace it with "that" and then show the modified content.

I have an input box with a 'did you mean' box that pops up under it, and it pulls it's results from another php page, however when a term with a space in it, such as "I am" vs. "Im" is entered, it stops working. This is the code I'm using to pull the results. So I made a added a simple string replace to change each space into '+';
search = $('#search').val().replace(' ','+');
search.keyup(function() {
results.load('results.php?q=' + search);
});
But for some reason it is only changing the first space into a '+'; so for example: "Hello how are you" = "Hello+how are you". But I need it to change to "Hello+how+are+you";

i need some creative input. i'm trying to enable the user to input a
length of time, from one day to about 10 years. ideas i've had have
been:
- 3 pull down boxes, for days, months, years
- an entry box for a value and a pull down box for units (days, weeks,
months, years)
- a scroll bar to slide along to a corresponding time
I'm not sure i should even use javascript, maybe an applet instead. I'd
really appreciated some new ideas or brainstorming.
I have a problem with getting the amount of childs in a XML structure,
the strucure is somewhat like the following:
<?xml version="1.0" encoding="iso-8859-1"?>
<cms>
<num>21</num>
<xmlnames>
<field>id</field>
<field>name</field>
<field>availablefrom</field>
<field>availableuntill</field>
<field>owner</field>
</xmlnames>
</cms>
If I use the following to get te amount of childs for xmlnames I get an
amount of 11:
xmlObj.responseXML.getElementsByTagName('xmlnames' )[0].childNodes.length
Is this wrong or maybe there is a better / other way of counting the
child amount?
I am running a bit of JS to highlight text inputs onFocus in IE. It
seems to be working on all of the forms on the site except one. The
debug code in the script displays the number of input elements in an
alert. On the page where it does not work, the alert is "[object]".
Here is the script:
function initHighlight() {
if (!document.getElementsByTagName){ return; }
var allfields = document.getElementsByTagName("input");
alert (allfields.length); // debug
for (var i=0; i<allfields.length; i++){
var field = allfields[i];
var attr = field.getAttribute("type");
if (attr == "text" || attr == "password") {
field.onfocus = function () {
this.className = 'highlightActiveField'
}
field.onblur = function () {this.className =
'highlightInactiveField'}
}
}
}
function addLoadEvent(func)
{
var oldonload = window.onload;
if (typeof window.onload != 'function'){ window.onload = func; }
else { window.onload = function() { oldonload(); func(); } }
}
var isIE = navigator.appName.indexOf("Microsoft") != -1;
if (isIE) { addLoadEvent(initHighlight); }
Unfortunately, I cannot reveal the URL of the page (contractural
restrictions).
Under what conditions would IE believe that the length of input fields
is an object, not a number? I have run the page through two
different validators and there are no errors.
I have a standard ul list where I need to keep count of the li's within (users can add/remove). This is my function when they remove a list item (.remove is inside the li), it removes the li fine but I always get zero for the rows.

I want to add some length validaitons to this form so that the state is enterted two characters long, the zip is entered five charaters long and the phone number will be entered eight characters long. Code:
