JavaScript - Array.length Not Returning Correct Number Of Results
Hello, another noob question for you: I have a function that requires the ability to count the number of entries in an array.
I'm using the following to call my function inside an input tag: Code: onblur="javascript:check(this.name, this.value, 1, 10);" which for example is calling check('field1', 'foobar', 1, 10) Here is the javascript: Code: function check(name, value, min, max){
var errors=new Array();
if(value.length < min || value.length > max){ //checking against min/max length of value
errors[name] = "Text field must not be blank.";
errors["blabla"] = "array value 2"; //added for testing purposes
alert(name+" : "+value); //returns "field1 : foobar"
}
alert(errors.length); // returns "0"
}
And when errors.length is alerted, it outputs 0. I can only figure that there is an issue when using custom named keys in an array, since this works when I use only integers, however, I have the need to use a custom key index as shown. Any ideas? Similar TutorialsAll, I have the following code: console.log("My num is: " + num); console.log("My lat is: " + lat); console.log("My lat length is: " + lat.length); console.log("My long is: " + long); When I get the output, I get the following: My num is: {"1":1,"2":2} My lat is: {"1":"40.59479899","2":"41.4599860"} My lat length is: 36 My long is: {"1":"-75.5549650","2":"-87.596430"} I'm confused on why the length is saying 36 when it's obviously two and the other output shows that??? My array is like so... shp[0][0] = 5; shp[0][1] = "A5"; shp[0][2] = "A2"; shp[0][3] = "A1"; shp[0][4] = "A4"; shp[0][5] = "A3"; shp[1][0] = 4; shp[1][1] = "C3"; shp[1][2] = "C4"; shp[1][3] = "C1"; shp[1][4] = "C2"; shp[2][0] = 3; shp[2][1] = "E1"; shp[2][2] = "E3"; shp[2][3] = "E2"; shp[3][0] = 3; shp[3][1] = "G3"; shp[3][2] = "G2"; shp[3][3] = "G1"; shp[4][0] = 2; shp[4][1] = "I2"; shp[4][2] = "I1"; the results I am after is... shp[0][0] = 5; shp[0][1] = "A1"; shp[0][2] = "A2"; shp[0][3] = "A3"; shp[0][4] = "A4"; shp[0][5] = "A5"; shp[1][0] = 4; shp[1][1] = "C1"; shp[1][2] = "C2"; shp[1][3] = "C3"; shp[1][4] = "C4"; shp[2][0] = 3; shp[2][1] = "E1"; shp[2][2] = "E2"; shp[2][3] = "E3"; shp[3][0] = 3; shp[3][1] = "G1"; shp[3][2] = "G2"; shp[3][3] = "G3"; shp[4][0] = 2; shp[4][1] = "I1"; shp[4][2] = "I2"; so it sorts all from the second part of the array to the end in alpha-numerical order. I tried the following but i get errors about Cannot call method 'unshift' of undefined. // var shp; var shpbk; var shpbktemp; // shpbk = shp.slice(); shpbktemp[0] = shpbk[0][0]; shpbk[0] = shpbk[0].shift; shpbk[0] = shpbk[0].sort; shpbk[0] = shpbk[0].unshift(shpbktemp[0]); shpbktemp[1] = shpbk[1][0]; shpbk[1] = shpbk[1].shift; shpbk[1] = shpbk[1].sort; shpbk[1] = shpbk[1].unshift(shpbktemp[1]); shpbktemp[2] = shpbk[2][0]; shpbk[2] = shpbk[2].shift; shpbk[2] = shpbk[2].sort; shpbk[2] = shpbk[2].unshift(shpbktemp[2]); shpbktemp[3] = shpbk[3][0]; shpbk[3] = shpbk[3].shift; shpbk[3] = shpbk[3].sort; shpbk[3] = shpbk[3].unshift(shpbktemp[3]); shpbktemp[4] = shpbk[4][0]; shpbk[4] = shpbk[4].shift; shpbk[4] = shpbk[4].sort; shpbk[4] = shpbk[4].unshift(shpbktemp[4]); I find it odd that this function is returning the day as 1, when it is clearly the 28th. when I run the code the answer I get looks like this: 1-Feb-2011 9:27 Code: function getDateTime(when) {
var theDate = new Date();
var day = theDate.getDay();
var month = theDate.getMonth();
var year = theDate.getFullYear();
var myTimeArr = theDate.toTimeString().split(":");
var monthNumber = new Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec")
when.value = day + "-" + monthNumber[month] + "-" + year + " " + myTimeArr[0] + ":" + myTimeArr[1];
any advice? I have a string of text, and starting from a particular spot (known to be a number), I want to find the length of that number. Here's what I have: Code: ...
var start = [...predetermined...]
var end = 0;
while (!isNaN(sourceCode.charAt(start + end))){
endCurrent++;
}
var myNum = sourceCode.substr(start, end) * 1;
So let's say var sourceCode = "alkdjabjasdsdf-53 dnalsdb..."; , startCurrent will already be at the "5" and I want to be able to extract the "53". What I have works, but it seems cumbersome... Any advice? I am trying to create a Table of Contents from a html document that has h1, h2, and h3 tags. In my js code i retrieve the h3 tags for a given h2 tag and store it into a variable called numSubs then in my for loop i set the condition j < numSubs.length but the problem is that it keeps saying that numSubs.length is 0 so the for loop never gets implemented. Can you tell me why numSubs.length keeps getting set to 0 when it should be 1 or two? Code: var subs = "sub" + (i + 1);
var numSubs = document.getElementsByName(subs);
alert(numSubs.length);
for(j=0; j < numSubs.length; j++)
{
alert();
toc.innerHTML += "<li>" + numSubs.item(j).innerHTML + "</li>";
}
this is the body of the html Code: <h1>Boolean Algebra</h1>
<h2>Fundamental Boolean functions</h2>
<h3 name = "sub1">Boolean Wrapper Class</h3>
<h3 name = "sub1">Boolean Computations</h3>
<h2>Computational Completeness</h2>
<h3 name = "sub2">Calculating Machanics</h3>
<h2>Identities of Boolean algebra</h2>
<h3 name = "sub3">NAND and NOR</h3>
<h2>NAND and NOR</h2>
I am having some trouble with this form and I was hoping someone could help me with it. It is not returning any errors, it is simply not returning the results of the form fields. The clear form works, the redirect works, the layout is fine, just no results. I am just beginning to learn Javascripts and I know this is a pretty basic script, but could someone be so kind to show me what it is I am doing wrong and teach me the right way to do this? I know it has to be something very simple but I keep going over it and i can not see what I am doing wrong. Rather than just post a snipit of the code I included the whole form so I do not forget to include any information. Thanks guys, I really appreciate it! Code: <form name="evaluation"

Hi, I'm a JS beginner and I find looping through arrays with for/in is very easy. Yet I find lots of code examples where array length is used instead of for/in and I'm thinking to myself, why do it this (somewhat) hard(er) way? Maybe I'm missing something... Thanks for your help. How do you take a long number such as Math.PI and break it out into an array? For example: [3] [.] [1] [4] [1] [5] [9] I suppose that because of the decimal you would have to convert it into a string first? It would be ideal if I could keep the number as a number without converting it to a string, but I'm not sure if that's possible. Every thread I've found online so far seems to indicate that you need a delimiter between the string you want to split up - that you can't just put every character of a string into an array... but there must be a way. I'm new to Javascript and to these forums. All suggestions welcome. Thanks. I have this simple php array. The array will dynamically pull results from the db in the future. PHP Code: <?php $dataArray = array ( 'id1' => array ( 'icon' => '<img src="images/piicon.png">', 'app' => 'GGP', 'timestamp' => date('m/d/y'), 'location' => 'Bellevue', 'comments' => 'It works!', ), 'id2' => array ( 'icon' => '<img src="images/piicon.png">', 'app' => 'Meijer', 'timestamp' => date('m/d/y'), 'location' => 'San diego', 'comments' => 'It works!', ), 'id3' => array ( 'icon' => '<img src="images/piicon.png">', 'app' => 'Point Inside', 'timestamp' => date('m/d/y'), 'location' => 'Boston', 'comments' => 'I guess its working? Maybe not exactly what we want yet though?!', ) ); echo json_encode($dataArray); ?> Currently if I have 100 results in my array, 100 results will be added to the table, 75 = 75 rows etc. What I am trying to plan out is a logical way to display one result from the array at a time. I am not looking for a chunk of jquery as an answer, better yet would be a plan/idea a programmer would you use to solve this. PHP Code: $(document).ready(function() { setInterval(function() { // get data $.ajax({ url: '/ajax/data.php', type: "GET", cache: false, error: function(data) { $("div#error").html('error: '+data); }, success: function(data) { var jsonObj = jQuery.parseJSON(data); jQuery.each(jsonObj, function(index, value) { var newRow = $("<tr><td>"+value.icon+"</td><td>"+value.app+"</td><td>"+value.timestamp+"</td><td>"+value.location+"</td><td>"+value.comments+"</td></tr>"); $("#mainTable tbody").prepend(newRow); }); } }); }, 5000); }); thanks The code below looks elementary, but it gives absurd results. Can you tell how I should have written it? I am slowly beginning to understand why it fails. But I do not understand why the JavaScript tutorials I've studied never warned against this trap. Any ship needs a list of crew members. The total number of persons onboard must be known too, for the case the ship sinks. We place these two properties in a prototype, so that we won't have to repeat them for each kind of ship. A passenger list is needed only if the ship is a passenger ship, so we decide not to place the passenger list in a prototype. Code:
function Ship() {
this.crew = [];
this.persons = 0;
}
function PassengerShip(name) {
this.name = name;
this.passengers = [];
}
PassengerShip.prototype = new Ship;
Passengers and crew arrive one by one shortly before departure. The first thing they do onboard is to check in: Code: Ship.prototype.checkin = function(list, person) {
this[list].push(person);
++this.persons;
}
(Instead of the push function, we could as well have used a statement such as Code: this[list][ this[list].length ] = person; I have tried. Same wrong result.) Let us launch two passenger ships and check some persons in. Code: var msFloat = new PassengerShip("M/S Float");
msFloat.checkin("crew", "Captain");
msFloat.checkin("crew", "Cook");
msFloat.checkin("passengers", "Alice");
msFloat.checkin("passengers", "Bob");
var msFlawed = new PassengerShip("M/S Flawed");
msFlawed.checkin("crew", "Capt'n");
msFlawed.checkin("crew", "Sailor");
msFlawed.checkin("passengers", "Charlie");
The shipping company wants a report when everybody has checked in. But I'm not sure they will like it: Code: Ship.prototype.report = function() {
function makeList(ship, list) {
if (!ship[list]) return (ship.name + " has no list of " + list + ".\n");
if (!ship[list].length) return (ship.name + " has no " + list + ".\n");
return (list + ": " + ship[list].join(", ") + "\n");
}
alert("\nPre-Departure Report For '" + this.name + "'\n\n" +
makeList(this, "passengers") + makeList(this, "crew") +
"\nNumber of persons onboard: " + this.persons + "\n\n");
}
msFloat.report(); // OK: Alice, Bob as passengers; Captain, Cook as crew
msFlawed.report(); // WRONG CREW: Captain, Cook, Capt'n, Sailor
The number of persons (passengers + crew) is reported correctly for both ships, and so is the passenger list. But the "M/S Flawed" reports four crew members. Two of those never checked in on that ship. How can such a thing happen? What kind of blunder did I make? An "edit+execute" version of the code is available at bjarne.altervista.org/sailor.html together with a little testoutput, some considerations based on that testoutput, and a workaround (which is not the same as a solution - it looks ridiculous). It seems as if arrays placed in prototypes do not always work as expected. Can that be true? The testoutput suggests that JavaScript sometimes forgets to create a much-needed own property in the this object, and instead changes the prototype. But that sounds incredible, doesn't it? I am not too familiar with the deeper theory of JavaScript, and I hope to get a response. Here is the code concatenated and embedded: Code: <?xml version="1.0" encoding="utf-8"?>

I have spent much time struggling with this kind of error, which is reproducible in 5 different browsers. This is the first time I have been able to reproduce it in a form that can be presented to others. Is there a well-established programming practice that can prevent it? What do experienced JavaScript programmers do? Regards Bjarne Pagh Byrnak Right now I am trying to grab all the links on a html page a store them in an array so that they can be accessed by a loop that makes sure that each one works. Right now I am not getting very far with it. If someone could help me I would be greatly appreciative.
Hi everyone, i am developing a facebook application and here i am, struggling with this piece of code. I have this php query result he $id = $facebook->api(array('method' => 'fql.query', 'query' => "SELECT uid FROM user WHERE uid IN( SELECT uid FROM page_fan WHERE page_id='411133928921438' AND uid IN ( SELECT uid2 FROM friend WHERE uid1 = me() ))")); And i need to save it as an array like: var user_ids = [x,y,z] etc etc...

I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?
When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689 .toFixed ( 2 ) ==> "15.24" So does it convert the number into string? Hello. I wonder is there any javascript to calculate IP length For example I have Start ADDR: VLAN_ADDR which is: 10.52.28.0 Stop ADDR: VLAN_LAST which is 10.52.29.254 As I know:result is 512 or another example: Start ADDR: VLAN_ADDR which is: 10.52.64.11 Stop ADDR: VLAN_LAST which is 10.52.64.15 As I know:result is 5 How to count it in javascript code ? Results are "numbers" Best regards Leos. For some reason i'm getting the error of "length is null". Which is from this . Code: 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: Code: 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 |
