JavaScript - Using New With Variable Length Arguments?
I want to use the new keyword to instantiate an object. The catch is I want to pass in variable length arguments.
Given: Code: function Foo () {
this.args = Array.prototype.join.call (arguments);
}
var args = ["arg0", "arg1", "arg2"];
The following don't work (though I understand why): Code: new Foo.apply (null, args); new (Foo.apply (null, args)); (new Foo).apply (null, args); Any ideas on how to do what I want without modifying Foo's source code? Similar TutorialsMy 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]); Hi all, I am trying to pass some dynamic values for use with javascript or more specifically AJAX... I had a set up looking something like the following; Code: <input type="button" onclick="ajaxFunction()" value="Add Favourite"/> <input type="text" name="school_id" id="school_id" value="<?php echo $school_id; ?>" /> <input type="text" name="teacher_id" id="teacher_id" value="<?php echo $teacher_id; ?>" /> Code: <script language ="javascript" type="text/javascript">
<!--
//Browser Support Code
function ajaxFunction(){
var ajaxRequest; // The variable that makes Ajax possible!
try{
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
}catch (e){
// Internet Explorer Browsers
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
}catch (e) {
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
}catch (e){
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
// Create a function that will receive data
// sent from the server and will update
// div section in the same page.
ajaxRequest.onreadystatechange = function(){
if(ajaxRequest.readyState == 4){
var ajaxDisplay = document.getElementById('ajaxDiv');
ajaxDisplay.value = ajaxRequest.responseText;
}
}
// Now get the value from user and pass it to
// server script.
var school_id = document.getElementById('school_id').value;
var teacher_id = document.getElementById('teacher_id').value;
var queryString = "?sid=" + school_id;
queryString += "&tid=" + teacher_id;
alert(queryString);
ajaxRequest.open("GET", "ajax_insert_favourite.php" + queryString, true);
ajaxRequest.send(null);
}
//-->
</script>
however because it is possible for there to be more than one button, i.e. many teachers can be returned the javascript would also output 1 and 1. I need someway of making this unique to the id's... I think that passing arguments/params might be the solution but I'm having a hard time implementing it; I've tried the following; Code: <input type="button" onclick="ajaxFunction('school_id','teacher_id')" value="Add Favourite"/>
Code: <!--
//Browser Support Code
function ajaxFunction(school_id,teacher_id){
But once I do this, it no longer even make the call. Can anyone advise here, I'm a relative newbie to javascript/AJAX etc. Many thanks, Greens85 Should be simple, but I'm having a complete brain fart. I need to call a function, with a parameter that triggers something relative to that parameter. Pseudo Example Code: function respawn(n) {
case 1
//respawn monster1 code
case 2
//respawn monster 2 code
case 3
//respawn monster 3 code
}
if(killed monster1) {respawn(1)} //respawn(monster1) is what I want to do
if(killed monster2) {respawn(2)}//respawn(monster2) is what I want to do
if(killed monster3) {respawn(3)}//respawn(monster3) is what I want to do
I can... Code: function respawn1(){
//respawn monster1 code
}
function respawn2() {
//respawn monster2 code
}
function respawn3() {
//respawn monster3 code
}
if(killed monster1) {respawn1()}
if(killed monster2) {respawn2()}
if(killed monster3) {respawn2()}
but if I have 10+ monsters I just figured a case structure would be good, or passing the monster to respawn to a single respawn() function......but all the switch examples I could find were based on dateTime which gave case 1-7 based on what day it was, and didn't show how you set your own cases like monster1, monster2, monster3.... I know this is a basic concept...I've read about functions he http://www.quirksmode.org/js/function.html and at w3schools of course but can't figure out how to apply it to my situation Thanks Hope you can help. I'm currently building a website and trying to integrate a javascript image 'tranisition' effect into mm_swapimage and failing. My knowledge of Javascipt is limited but without knowing the 'arguments' for mm_swapimage, it's impossible (looks similar to vb, but can't find an answer anywhere) I want the effect to work on a 'timed' event rather than 'OnMouseOver' so have added script to change that (which is probably the issue!) I can get both to work idependantly but not together. I've simplified the page and pasted the code below, as it stands the 'effect' works, but it only uses the primary image, not the other image in the array. I'm using DW CS4 and the transition extension is called FlevOOware.

I am a newbie and am writing a function. I want the function to refer to an arrays elements to get the biggest, but I dont know how to do this. Here is the code: Code: function unique(first,second,third)
{
var answer;
if (first > second)
{
answer = first - second;
}
if (second > third)
{
answer = second - third;
}
if (third > first)
{
answer = third - first;
}
return answer;
}
//function call
unique (digitArray(0,1,2));
what I am trying to do, is get the array elements to be called and give me an answer. Will I need to add the array to the function? It is further down the code after the function at the moment. Or will I need to add the array elements to the function? Hope it is clear Let's say I'm defining an object and I want the constructor to take one input and ten save it. I'd like to do something like this: function apple(color) { this.color = arguments.color; } But of course that doesn't work because arguments isn't a scope. My question is, is there a scope I can use. What I've been doing instead is this: function apple(new_color) {this.color = new_color;} But that just seems less than perfectly pretty. i've got a project to be done using javascript and html....i don't know how to pass the arguments from <input type="text"> to the javascript function i'm using in my program. i just want the javascript script to calculate the input given by the user and return the answer. here is the program: Code: <html>

pls it would be of great help. Thanx. Hi all, I have a newbie question. I have just started working with javascript and would appreciate some guidance. I have a webpage and there are products for sale on it(this is not live it is merely being used as practice project). Beside each product is a description a price and an 'add to cart' button. My cart is simply a div with an id of 'cart' and it has a text box within it. I need the product name to be displayed within the div (this, I have working), I also need to display the product price in the text box once the button(add to cart ) for that particular product has been pressed. Also when the button for another product is pressed, I want the cost/value for that product to be added to the other value and displayed in the text box in the cart div... I apologise for rambling on but this is the best way of me explaining my needs.... Here's where i am right now.. The HTML snippet Code: <div id ="cart">
<p><img src="images/shopping-cart.png" alt ="cart"/>Your Cart</p>
<div id="sum"><!--(this is the div where the total goes)-->
<input type="text" id="total" value="0" /><p>€ Your Total <input type="reset" value = "reset" /></p>
</div>
</div>
<h2 id ="black">Blackcurrent<br /></h2>
<p>€ 12.00 <input type = "submit" value ="add to cart" onClick = "shoppingCart('Blackcurrent',12)" /></p>
And the javascript: Code: alert ("working");
function shoppingCart (itemName,itemValue)
{
/* var thePrice = Number(itemValue);
return thePrice;*/
document.getElementById ("cart").innerHTML += itemName + "<br/>";
document.getElementById('total').value = Number(document.getElementById('total').value) + itemValue;
}
I hope i have posted correctly and am aware that i have only posted a segment of the HTML.. Please let me know if you need any more code or info.. Thanks a lot in advance for any help... Code: <html>

I have a project that uses and Ajax call but it appears that the call back function cannot take arguments, nor return values. However, I have wrapped another function inside the call back function that takes xmlhttp.responseText as the argument and returns values that are supposed to be placed in a global array. If I do, for instance: callback function code.... globalArray = someFunction(xmlhttp.responseText) alert(globalArray), I get the expected values. but a function is called later to query the contents of the global array the global array is empty (No other code or functions exist in this project to alter the global array) Primary dev client is FireFox 3x on Mac OSX Is this a bug, or is there some other aspect of javascript that I need to know about? I am using ajax here because javascript does not have an array shuffling function and php does. So I send an array to the server, have it shuffled by the server and returned to the requesting page. 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 Overview: Order entry project. I am using an iFrame to pull external forms that I can not change. Once our employee enters in the information and submits I would like to redirect the existing window to a new page. I've tried many variations of: Code: <script type='text/javascript'>
function iHistory() {
var hist=history.length;
if (hist>1)
{
parent.window.location = "orderentry.php";
}
}
</script>
Since I have no control of the external form I have been using OnLoad() in the iFrame tag to call iHistory(). The script works great unless the browser history is >1 If possible, I would like to also setup like a 5 or 10 second delay so the employee can see the framed confirmation page before redirect. So the function needs to check current history.length, when that changes delay 5-10 seconds and redirect parent window to orderentry.php function checkValidFormInput() { if (document.getElementsByName('customerName').value != '') { document.getElementById('customerNameImg').innerHTML = '<img alt="Valid" src="images/greenTick.png">'; } else { document.getElementById('customerNameImg').innerHTML = '<img alt="Invalid" src="images/redX.png">'; } if (document.getElementsByName('customerEmail').length > 0) { document.getElementById('customerEmailImg').innerHTML = '<img alt="Valid" src="images/greenTick.png">'; } else { document.getElementById('customerEmailImg').innerHTML = '<img alt="Invalid" src="images/redX.png">'; } } Ok I have a textarea field that is validated by Js, this textarea can and will contain the newline character Code: \n so I validate in JS Code: 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 Code: 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. Any ideas? Any suggestions as to how I can make php and javascript treat a newline as the same amount of characters? Thanks in advance. I'm trying to figure out how to add a length paramater to this function. Not quite sure how to do it. here's what I tried: Code:
var phone = document.getElementById('phone');
if(isNumericdashes(phone, "Please enter a valid phone number")){
return true;
}
function isNumericdashes(elem, helperMsg){
var numericExpression = /^[0-9\(\)-]+$/;
if(elem.value.match(numericExpression) &&(elem.length > 9)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}

I write code using ext js,openlayers and GeoExt for measuring length and area ,it is working inside inside of india in the world map but this measure tool is not working outside of india in the world map. My code for Measure length: To Load map: var projWGS84 = new OpenLayers.Projection("EPSG:4326"); var projSphericalMercator = new OpenLayers.Projection("EPSG:900913"); var bounds = new OpenLayers.Bounds(68.137, 6.783, 97.336, 37.086); bounds.transform(projWGS84, projSphericalMercator); map.maxExtent = bounds; var gphy = new OpenLayers.Layer.Google("Google Street", { 'sphericalMercator':true //maxExtent: new OpenLayers.Bounds(-20037508, -20037508,20037508, 20037508) } ); var osmLayer = new OpenLayers.Layer.OSM(); // Add the background images via WMS // Add the background images via WMS //map.addLayer(bglayer); // map.addControl(new OpenLayers.Control.MousePosition()); map.addLayers([gphy, osmLayer]); Measure Length: Measure = new Ext.SplitButton({ text:"Measure", iconCls:"icon-measure-length", toggleGroup:"navigate", group: "navigate", enableToggle:true, allowDepress:false, handler: function(button, event) { // allowDepress should deal with this first condition if(!button.pressed) { button.toggle(); } else { button.menu.items.itemAt(activeIndex).setChecked(t rue); } }, listeners: { toggle: function(button, pressed) { // toggleGroup should handle this if(!pressed) { button.menu.items.each(function(i) { i.setChecked(false); }); } }, render: function(button) { // toggleGroup should handle this Ext.ButtonToggleMgr.register(button); } }, menu: new Ext.menu.Menu({ items: [ new Ext.menu.CheckItem( new GeoExt.Action({ text: "Length", toggleGroup:"navigate", iconCls:"icon-measure-length", group: "navigate", enableToggle:true, allowDepress:false, map: map, control: new OpenLayers.Control.Measure(OpenLayers.Handler.Path , { eventListeners: { measu function(evt) { Ext.MessageBox.show({ title: 'Line length :', buttons: Ext.MessageBox.OK, width:200, msg:"Line Length: " + evt.measure.toFixed(2) + " " + evt.units }); } } }) }) ) } }) }) ) ] }) }) Hi, I have added an validation script for Pizza menu. Validation working fine in all browsers except IE. When I working in IE8 it throws an error "length is null or not an object error in IE8". Please help me. See Java script code below: <script> function UnCheckRadios(radioButtonGroupName) { var formName = "frmOrder"; var form = document.forms[formName]; alert(form); var noOfRadioButtons=form[radioButtonGroupName].length; for(var x=0;x<noOfRadioButtons;x++) { chk=form[radioButtonGroupName] .checked=false; } } </script> PHP code: <input type="radio" id="<?=$subitem['subgroup_id'];?>_comboleft" name="<?=$subitem['subgroup_id'];?>_comboleft" value="<?=$subitem['id'];?>:Left Side" onclick="UnCheckRadios('<?=$subitem["subgroup_id"];?>_combowhole');"> All, 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??? How can I call a function in javascript like: Code: var x = string.Length ??? and not like: Code: var x = Length(string); (just for arguments sake) (Also please don't suggest JQuery, I'm doing this to learn!) Thanks! |
