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:
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?
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".
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:
I'm attempting to run some checks on an input value. Initial HTML:[code]After the page loads a javascript calendar function called JDPicker runs and changes it to:[code] my issue only occurs on this HTML that is hard coded into the page. I have several other inputs (same element structure with the divs, etc) added later with javascript using createElement functions and my javascript works fine on those:[code]My problem is only in IE (testing with v 8). When I try to get the child elements value it gives me this error: "value null or is not an object". I tried using .nodeValue after that and it worked, but then started giving me errors regarding the .length function "length null or is not an object".
I want to know the length in pixels of a document embedded in a iframe. The way I go seems to work under IE but not under Firefox (about other browsers I'll see later). Code:
I have added two numbers from two table cells together using parseInt & innerHTML. I have this stored in a variable. I want to get the length of this number. I need to convert it to a string variable using toString and then access its length method. Whats the best way of doing this? I tried using toString then length but I am only getting "object window"!
I have a textarea field that is validated by Js, this textarea can and will contain the newline character so I validate in JS if(textareaname.value.length < 200)this hten goes through to my php where i also check before I place in to the Database using MYSQL,if( strlen($_POST['textareaname']) < 200 )but my php is giving me a different string length from my javascript.It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.how I can make php and javascript treat a newline as the same amount of characters?
this is a simple script, that uses ajax that sends to the server the total amount of time (in seconds) that the visitor was reading or whatever.
var startime=(new Date()).getTime();window.onunload=function(){ var x=(window.ActiveXObject)?new ActiveXObject('Microsoft.XMLHTTP'):new XMLHttpRequest(); x.open("GET","count.php?t="+(((new Date()).getTime()-startime)/1000),true);x.send(null)}
I have the following JS load up via file in the headers of my HTML[code]...
No matter how many times I run the function, it returns 0 for the first two alerts. The first time I run it, it should output "1", then "3". The next time should be "2", "3". Am I instantiating/populating the JS arrays incorrectly? Been working on this for 2 hours, shouldn't be taking this long
I want to add the + but stop when i reaches the checked length minus 1.
Code javascript: var checkedlength=0; for(i=0;i<document.getElementsByName('checkresult').length;++i){ if (document.getElementsByName('checkresult')[i].checked){
[Code]....
I realize that document.getElementsByName('checkresult').length in if(i<document.getElementsByName('checkresult').length-1) is not the same as the checked.
